在php5.4之前可以启用安全模式和目录权限防范跨站的问题,另外也可以通过配置PHP.ini进行防范,参考:LNMP下防跨站、跨目录安全设置,仅支持PHP 5.3.3以上版本
php5.4之后没有了安全模式,这里提供一个解决方案,动手能力较好的朋友可以动手试试。提供了比较完善的安全环境,设置了shell chroot、隔离php执行身份、目录权限等。默认为每个用户设置了open_basedir,因为做了chroot,所以没有禁用php的函数。
特点:
1、高效的http请求处理能力,系统负载低
2、安全的SSH环境,php执行权限分离,各用户间互不影响
架构的简单说明
1、由Nginx处理http请求,nginx运行属主身份为www:www,执行php代理到后端php-fpm,php-fpm负责管理各用户间的php进程,用户运行php的组权限为nobody
2、默认为每个用户提供了SSH,方便用户直接进行管理。限定各SSH用户只能访问家目录的文件,访问系统级命令和访问其他非属主身份的路径显示为无权限。
3、关于用户目录权限的说明,建立的用户属主身份为user:nobody,家目录自身权限:drwxr-x--x,其创建的目录权限设置为drwx---r-x,文件权限设定为-rw----r--。(user为当前用户)
4、通过设定系统umask及ftp服务umask,确保用户家目录下创建的文件权限为-rw----r--,目录权限为drwx---r-x
基本信息:
用户家目录为/home/chroot/home/$user,软链接至/home/$user
nginx 路径:/usr/local/nginx
php 路径:/usr/local/php5.4
php-fpm全局配置:/usr/local/php5.4/etc/php-fpm.conf
php-fpm pools配置:/usr/local/php5.4/etc/fpm.d/php-fpm-$user.conf
mysql 路径:/usr/local/mysql
mysql Data路径:/usr/local/mysql/data
pureftpd 路径:/usr/local/pureftpd
Modify路径:/usr/local/sbin/Modify #创建用户、域名、数据库直接运行脚本Modify
以Centos 6.3 64bit为例,按照下述过程编译
如果是安装在小内存的VPS上,建议增加swap空间,以免后面编译php时出现内存不足的问题
dd if=/dev/zero of=/var/swapfile bs=1024 count=512000
/sbin/mkswap /var/swapfile
/sbin/swapon /var/swapfile
echo "/var/swapfile swap swap defaults 0 0" >> /etc/fstab
先安装必备的开发库,这里我一股脑把后面所需的软件包都安装了,最后再进行无依赖包的清理工作。
yum -y install gcc gcc-c++ file bison patch unzip mlocate flex wget diffutils automake autoconf kernel-devel lsof gd cpp readline-devel openssl openssl-devel vim-minimal nano sendmail libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel libtidy libtidy-devel zlib zlib-devel glibc glibc-devel libc-client libc-client-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel libidn libidn-devel openldap openldap-devel openldap-clients openldap-servers net-snmp net-snmp-devel nss_ldap gettext gettext-devel expat-devel libcap libcap-devel libtool libtool-ltdl-devel pam-devel pcre-devel ncurses-devel subversion bind-utils rsync libxslt groff pkgconfig
一、编译autoconf、libiconv、libmcrypt、mhash、mcrypt等
cd /usr/local/src
wget -c http://ftp.gnu.org/gnu/autoconf/autoconf-2.69.tar.gz
wget -c http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
wget -c http://dl.icodex.org/lnamp-1.0/src/libmcrypt-2.5.8.tar.bz2/mirror
wget -c http://dl.icodex.org/lnamp-1.0/src/mhash-0.9.9.9.tar.bz2/mirror
wget -c http://dl.icodex.org/lnamp-1.0/src/mcrypt-2.6.8.tar.gz/mirror
cd /usr/local/src
tar -zxvf autoconf-2.69.tar.gz
cd autoconf-2.69/
./configure
make && make install
cd /usr/local/src
tar -zxvf libiconv-1.14.tar.gz
cd libiconv-1.14/
./configure
make && make install
cd /usr/local/src
tar -jxvf libmcrypt-2.5.8.tar.bz2
cd libmcrypt-2.5.8/
./configure
make && make install
/sbin/ldconfig
cd libltdl/
./configure --enable-ltdl-install
make && make install
cd /usr/local/src
tar -jxvf mhash-0.9.9.9.tar.bz2
cd mhash-0.9.9.9/
./configure
make && make install
ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la
ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so
ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4
ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8
ln -s /usr/local/lib/libmhash.a /usr/lib/libmhash.a
ln -s /usr/local/lib/libmhash.la /usr/lib/libmhash.la
ln -s /usr/local/lib/libmhash.so /usr/lib/libmhash.so
ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2
ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib/libmhash.so.2.0.1
cd /usr/local/src
tar -zxvf mcrypt-2.6.8.tar.gz
cd mcrypt-2.6.8/
/sbin/ldconfig
./configure
make && make install
if [ `getconf WORD_BIT` = '32' ] && [ `getconf LONG_BIT` = '64' ] ; then
ln -s /usr/local/lib/libiconv.so.2.5.0 /lib64/libiconv.so.2
fi
二、安装数据库。这里启用了Google 开发的“google-perftools”中的TCMalloc,以增加数据库在高并发下的性能,降低系统负载。同时TCMalloc也同样适用于nginx,因此我们先安装TCMalloc库。以下是安装步骤
1、64位操作系统请先安装libunwind库,32位操作系统不要安装。libunwind库为基于64位CPU和操作系统的程序提供了基本的堆栈辗转开解功能,其中包括用于输出堆栈跟踪的API、用于以编程方式辗转开解堆栈的API以及支持C++异常处理机制的API。
cd /usr/local/src/
wget http://mirror.yongbok.net/nongnu/libunwind/libunwind-1.0.1.tar.gz
cd /usr/local/src/
tar -zxvf libunwind-1.0.1.tar.gz
cd libunwind-1.0.1/
CFLAGS=-fPIC ./configure
make CFLAGS=-fPIC
make CFLAGS=-fPIC install
2、安装google-perftools:
cd /usr/local/src/
wget http://gperftools.googlecode.com/files/gperftools-2.0.tar.gz
tar -zxvf gperftools-2.0.tar.gz
cd gperftools-2.0
./configure --enable-frame-pointers
make && make install
3、修改增加动态链接库
echo "/usr/local/lib" > /etc/ld.so.conf.d/usr_local_lib.conf
/sbin/ldconfig
4、修改MariaDB启动脚本(这个步骤我们在后面编译好MariaDB之后再增加)
然后安装最新版开源MariaDB。从MySQL/MariaDB 5.5开始,源码编译构建工具从GUN Autotools换成跨平台的cmake。
1、首先编译安装cmake,当前最新版本为2.8.9
rpm -e cmake
cd /usr/local/src/
wget http://www.cmake.org/files/v2.8/cmake-2.8.9.tar.gz
tar -zxvf cmake-2.8.9.tar.gz
cd cmake-2.8.9;
./bootstrap
make
make install
cd /usr/local/src/
wget http://ftp.gnu.org/gnu/bison/bison-2.7.1.tar.gz
tar -zxvf bison-2.7.1.tar.gz
cd bison-2.7.1
./configure
make
make install
2、编译MariaDB,当前版本号为5.5.31
首先新建MariaDB运行用户(组)
/usr/sbin/groupadd -g 27 -o -r mysql
/usr/sbin/useradd -M -g mysql -o -r -d /usr/local/mysql/data -s /bin/false -c "MariaDB Server" -u 27 mysql
cd /usr/local/src/
wget -O mariadb-5.5.31.tar.gz http://mirror.yongbok.net/mariadb/mariadb-5.5.31/kvm-tarbake-jaunty-x86/mariadb-5.5.31.tar.gz
tar -zxf mariadb-5.5.31.tar.gz
cd mariadb-5.5.31.tar.gz
CFLAGS="-O3" CXX=gcc
CXXFLAGS="-O3 -felide-constructors -fno-exceptions -fno-rtti"
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DMYSQL_TCP_PORT=3306 -DMYSQL_UNIX_ADDR=/tmp/mysql.sock -DWITH_EMBEDDED_SERVER=0 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_PERFSCHEMA_STORAGE_ENGINE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DWITH_FEDERATEDX_STORAGE_ENGINE=1 -DWITH_ARIA_STORAGE_ENGINE=1 -DWITH_XTRADB_STORAGE_ENGINE=1 -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DENABLED_LOCAL_INFILE=1 -DWITH_EXTRA_CHARSETS=all -DWITH_READLINE=1 -DWITH_LIBWRAP=1 -DWITH_SSL=system -DWITH_ZLIB=system
make && make install
这里我把大部分数据库引擎都添加了,并设置默认字符集为utf8_general_ci,更多cmake选项,可以执行cmake . -LH|more进行查看。对于多核处理器,可以在make时增加-j选项,如8个核心:make -j 8
3、创建一些目录
mkdir -p /usr/local/mysql/InnoDB/redoLogs; mkdir -p /usr/local/mysql/InnoDB/undoLogs
chown -R mysql /usr/local/mysql/data
chgrp -R mysql /usr/local/mysql
mkdir /usr/local/mysql/logs /usr/local/mysql/tmp
chown mysql.mysql /usr/local/mysql/tmp
chown mysql.mysql /usr/local/mysql/logs
这里数据库data目录为/usr/local/mysql/data,为了方便习惯,也可以做个软连接到/var/lib/mysql
ln -s /usr/local/mysql/data /var/lib/mysql
chown -R mysql /var/lib/mysql
4、初始化第一个数据库mysql,这里存储了mysql用户表、权限表等
cd /usr/local/mysql
./scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql/data
5、设置修改配置文件my.cnf和init开机启动脚本
/usr/bin/install -m 755 /usr/local/mysql/support-files/my-innodb-heavy-4G.cnf /etc/my.cnf
/usr/bin/install -m 755 /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysqld
chkconfig --add mysqld
sed -i '69 s/max_connections = 100/max_connections = 1000/' /etc/my.cnf
sed -i '181 s/default-storage-engine = MYISAM/default-storage-engine = innodb/' /etc/my.cnf
sed -i '/myisam_recover/askip-name-resolvenskip-external-lockingnskip-host-cache' /etc/my.cnf
小内存机器建议修改innodb缓冲池大小,否则启动mysql后innodb将显示无法使用或无法启动服务
sed -i '368 s/innodb_buffer_pool_size = 2G/innodb_buffer_pool_size = 256M/' /etc/my.cnf
6、修改开机启动脚本,在/etc/rc.d/init.d/mysqld第46行、47行指定路径,直接用sed修改
sed -i '46 s#basedir=#basedir=/usr/local/mysql#' /etc/rc.d/init.d/mysqld
sed -i '47 s#datadir=#datadir=/usr/local/mysql/data#' /etc/rc.d/init.d/mysqld
7、修改MySQL启动脚本mysqld_safe,以支援TCMalloc,编辑文件/usr/local/mysql/bin/mysqld_safe,在# executing mysqld_safe的下一行,增加:#export LD_PRELOAD=/usr/local/lib/libtcmalloc.so 这里直接用sed修改了
sed -i '/# executing mysqld_safe/aexport LD_PRELOAD=/usr/local/lib/libtcmalloc.so' /usr/local/mysql/bin/mysqld_safe
8、收尾工作
echo 'PATH=$PATH:$HOME/bin:/usr/local/bin:/usr/local/mysql/bin' >> ~/.bashrc
source ~/.bash_profile
echo "/usr/local/mysql/lib" > /etc/ld.so.conf.d/mysql.conf
ldconfig
if [ `getconf WORD_BIT` = '32' ] && [ `getconf LONG_BIT` = '64' ] ; then
cd /usr/local/mysql
ln -s lib lib64
chown -R root.mysql lib64
fi
修改mysql root密码,这里使用生成的16位随机数,并将密码保存到/root/.my.cnf,这样管理员通过终端可直接跳过输入密码管理mysql服务(生产环境请不要这样做)。
service mysqld start
mysqlroot_passwd=`cat /dev/urandom | head -1 | md5sum | head -c 16`
echo $mysqlroot_passwd
/usr/local/mysql/bin/mysql -uroot -p
mysql<<EOF
use mysql;
update `mysql`.`user` set `password`=PASSWORD('$mysqlroot_passwd') where `User`='root';
flush privileges;
EOF
cat > /root/.my.cnf<<EOF
[client]
user=root
password=$mysqlroot_passwd
EOF
service mysqld stop
chmod 750 /usr/local/mysql /usr/local/mysql/data
chmod 640 /etc/my.cnf
chmod 600 /root/.my.cnf
三、安装Jailkit,Jailkit可以限制普通用户执行SSH时的家目录,旧版本会有一些问题,但最近这两年相当稳定,因此我在很多服务器都将其作为chroot必备的组件。后面php-fpm进行chroot设置时,也可以直接套用在这个基础上,因此这里先安装Jailkit。
1、安装最新版Jailkit,当前版本为2.16
cd /usr/local/src
wget -c http://olivier.sessink.nl/jailkit/jailkit-2.16.tar.gz
tar -zxf jailkit-2.16.tar.gz
cd jailkit-2.16
./configure
#sed -i '41 s#IBS =#IBS = -pthread#' src/Makefile
make && make install
设置开机启动
/usr/bin/install -m 755 extra/jailkit /etc/init.d/jailkit
chkconfig jailkit on
service jailkit start
2、创建chroot工作目录并设置权限,这里设置为/home/chroot
mkdir /home/chroot
chown root:root /home/chroot
chmod 751 /home/chroot
jk_init -v -j /home/chroot sftp scp jk_lsh extshellplusnet
jk_cp -v /home/chroot /usr/bin/id
jk_cp -v /home/chroot /usr/bin/unzip
jk_cp -v /home/chroot /usr/bin/zip
jk_cp -v /home/chroot /usr/bin/curl
jk_cp -v /home/chroot /etc/pki
jk_cp -v /home/chroot /usr/lib/libssh2.so.1
jk_cp -v /home/chroot /usr/lib/libcurl.so
jk_cp -v /home/chroot /usr/lib/libsoftokn3.so
jk_cp -v /home/chroot /usr/lib/libnssdbm3.so
jk_cp -v /home/chroot /usr/lib/libnss3.so
jk_cp -v /home/chroot /usr/lib/libnssckbi.so
jk_cp -v /home/chroot /usr/lib/libnsspem.so
jk_cp -v /home/chroot /usr/lib/libsmime3.so
jk_cp -v /home/chroot /usr/lib/libssl3.so
jk_cp -v /home/chroot /usr/lib64/libssh2.so.1
jk_cp -v /home/chroot /usr/lib64/libcurl.so
jk_cp -v /home/chroot /usr/lib64/libsoftokn3.so
jk_cp -v /home/chroot /usr/lib64/libnssdbm3.so
jk_cp -v /home/chroot /usr/lib64/libnss3.so
jk_cp -v /home/chroot /usr/lib64/libnssckbi.so
jk_cp -v /home/chroot /usr/lib64/libnsspem.so
jk_cp -v /home/chroot /usr/lib64/libsmime3.so
jk_cp -v /home/chroot /usr/lib64/libssl3.so
jk_cp -v /home/chroot /usr/bin/certutil
jk_cp -v /home/chroot /usr/bin/cmsutil
jk_cp -v /home/chroot /usr/bin/crlutil
jk_cp -v /home/chroot /usr/bin/modutil
jk_cp -v /home/chroot /usr/bin/pk12util
jk_cp -v /home/chroot /usr/bin/signtool
jk_cp -v /home/chroot /usr/bin/signver
jk_cp -v /home/chroot /usr/bin/ssltap
jk_cp -v /home/chroot /usr/lib/nss/unsupported-tools/atob
jk_cp -v /home/chroot /usr/lib/nss/unsupported-tools/btoa
jk_cp -v /home/chroot /usr/lib/nss/unsupported-tools/derdump
jk_cp -v /home/chroot /usr/lib/nss/unsupported-tools/ocspclnt
jk_cp -v /home/chroot /usr/lib/nss/unsupported-tools/pp
jk_cp -v /home/chroot /usr/lib/nss/unsupported-tools/selfserv
jk_cp -v /home/chroot /usr/lib/nss/unsupported-tools/strsclnt
jk_cp -v /home/chroot /usr/lib/nss/unsupported-tools/symkeyutil
jk_cp -v /home/chroot /usr/lib/nss/unsupported-tools/tstclnt
jk_cp -v /home/chroot /usr/lib/nss/unsupported-tools/vfychain
jk_cp -v /home/chroot /usr/lib/nss/unsupported-tools/vfyserv
jk_cp -v /home/chroot /usr/lib64/nss/unsupported-tools/atob
jk_cp -v /home/chroot /usr/lib64/nss/unsupported-tools/btoa
jk_cp -v /home/chroot /usr/lib64/nss/unsupported-tools/derdump
jk_cp -v /home/chroot /usr/lib64/nss/unsupported-tools/ocspclnt
jk_cp -v /home/chroot /usr/lib64/nss/unsupported-tools/pp
jk_cp -v /home/chroot /usr/lib64/nss/unsupported-tools/selfserv
jk_cp -v /home/chroot /usr/lib64/nss/unsupported-tools/strsclnt
jk_cp -v /home/chroot /usr/lib64/nss/unsupported-tools/symkeyutil
jk_cp -v /home/chroot /usr/lib64/nss/unsupported-tools/tstclnt
jk_cp -v /home/chroot /usr/lib64/nss/unsupported-tools/vfychain
jk_cp -v /home/chroot /usr/lib64/nss/unsupported-tools/vfyserv
mkdir -p {/home/chroot/opt,/home/chroot/tmp,/home/chroot/var/www}
chmod -R 755 /home/chroot/opt /home/chroot/var/www
chmod 1777 /home/chroot/tmp
echo "nobody:x:99:" >> /home/chroot/etc/group
echo "www:x:999:" >> /home/chroot/etc/group
echo "www:x:999:999::/home/www:/bin/nologin" >> /home/chroot/etc/passwd
chmod 644 /home/chroot/etc/group
chmod 644 /home/chroot/etc/passwd
3、修改监听chroot下的日志输出,方便debug
CentOS 5.x
service syslog stop
syslogd -a /home/chroot/dev/log
service syslog restart
CentOS 6.x
service rsyslog stop
rsyslogd -a /home/chroot/dev/log
service rsyslog restart
4、安装mini_sendmail,chroot环境下使用
#must install glibc-static under RHEL 6
yum install -y glibc-static
cd /usr/local/src
wget -c http://www.acme.com/software/mini_sendmail/mini_sendmail-1.3.6.tar.gz
tar -zxf mini_sendmail-1.3.6.tar.gz
cd mini_sendmail-1.3.6
wget -c http://dl.icodex.org/mini_sendmail_1.3.6.patch.tar.gz
tar -zxf mini_sendmail_1.3.6.patch.tar.gz
patch -p0 < mini_sendmail_1.3.6.patch
make
/usr/bin/install -m 755 mini_sendmail /home/chroot/usr/sbin/sendmail
四、编译PHP,这里选择了最新版本5.4.15。
1、首先创建用户
/usr/sbin/groupadd -g 999 -o -r www
/usr/sbin/useradd -M -g www -o -r -d /var/www/html -s /bin/false -c "Web Server" -u 999 www
2、开始编译
yum -y install libc-client-devel net-snmp net-snmp-devel libtidy-devel
cd /usr/local/src
wget http://www.php.net/get/php-5.4.15.tar.bz2/from/hk2.php.net/mirror
tar -jxf php-5.4.15.tar.bz2
cd php-5.4.15/
if [ `getconf WORD_BIT` = '32' ] && [ `getconf LONG_BIT` = '64' ] ; then withlib="--with-libdir=lib64" ; else withlib="--with-libdir=lib" ; fi
./configure --prefix=/usr/local/php5.4 --with-config-file-path=/usr/local/php5.4/etc --with-iconv-dir --with-freetype-dir --with-jpeg-dir --with-png-dir --with-libxml-dir --with-pcre-regex --enable-xml --disable-phar --disable-rpath --enable-calendar --enable-bcmath --enable-calendar --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --with-ldap --with-ldap-sasl --enable-exif --enable-soap --enable-fpm --with-fpm-user=www --with-fpm-group=www --enable-soap --with-snmp --enable-wddx --enable-mbstring --with-mcrypt --enable-ftp --with-gd --enable-gd-native-ttf --enable-gd-jis-conv --with-openssl --with-mhash --with-mysql=/usr/local/mysql --with-mysql-sock=/tmp/mysql.sock --with-mysqli=/usr/local/mysql/bin/mysql_config --enable-mysqlnd --with-pdo-mysql=/usr/local/mysql --enable-pdo --with-sqlite3 --with-pdo-sqlite --enable-pcntl --enable-sockets --with-xmlrpc --with-imap --with-imap-ssl --with-kerberos --with-tidy --with-bz2 --enable-zip --with-zlib --with-zlib-dir --without-pear --with-gettext --disable-ipv6 --disable-debug $withlib
make ZEND_EXTRA_LIBS='-liconv'
make install
3、设置开机启动脚本
/usr/bin/install -m 755 sapi/fpm/init.d.php-fpm /etc/rc.d/init.d/php-fpm
sed -i '/### END INIT INFO/aumask 072' /etc/rc.d/init.d/php-fpm # 该项是为了使chroot环境下php进程创建的文件(包括临时文件、上传的文件等)符合基本安全权限进行的设置
/sbin/chkconfig --add php-fpm
/sbin/chkconfig php-fpm on
4、安装pear,新版本编译安装时都没pear了
cd /usr/local/src
wget http://pear.php.net/go-pear.phar
/usr/local/php5.4/bin/php go-pear.phar
5、设置php.ini和常用的两个软链接
/bin/cp php.ini-production /usr/local/php5.4/etc/php.ini
ln -s /usr/local/php5.4/bin/php /usr/bin/php
ln -s /usr/local/php5.4/bin/phpize /usr/bin/phpize
6、创建php-fpm配置文件
mkdir /usr/local/php5.4/etc/fpm.d
cat >/usr/local/php5.4/etc/php-fpm.conf <<EOF
include=etc/fpm.d/*.conf
[global]
pid = run/php-fpm.pid
error_log = log/php-fpm.log
log_level = warning
emergency_restart_threshold = 10
emergency_restart_interval = 1m
process_control_timeout = 5s
process.max = 500
daemonize = yes
rlimit_files = 51200
rlimit_core = 0
events.mechanism = epoll
EOF
设置第一个php-fpm pool,文件名default.conf,没有开启chroot。
cat >/usr/local/php5.4/etc/fpm.d/default.conf <<EOF
[www]
listen = 127.0.0.1:9001
;listen = /usr/local/php5.4/var/run/php-fpm-www.sock
listen.allowed_clients = 127.0.0.1
listen.mode = 0666
listen.owner = www
listen.group = nobody
user = www
group = nobody
;chroot = /home/chroot

pm.min_spare_servers = 1
pm.max_spare_servers = 5
pm.max_requests = 1000
request_terminate_timeout = 30s

五、编译nginx,引入两个模块,因基本缓存需要而增加了ngx_cache_purge,因rewrite的需要而增加pcre库。
1、编译最新版nginx,加入SPDY模块和ngx_pagespeed模块
rpm -Uvh http://dl.iuscommunity.org/pub/ius/stable/Redhat/6/x86_64/ius-release-1.0-11.ius.el6.noarch.rpm
yum install git gcc-c++ make pcre-devel openssl-devel libxslt-devel gd-devel zlib-devel geoip-devel yum-plugin-replace
yum replace openssl --replace-with=openssl10 --enablerepo=ius-testing
cd /usr/local/src
wget -c http://nginx.org/download/nginx-1.4.1.tar.gz
wget -c http://labs.frickle.com/files/ngx_cache_purge-2.1.tar.gz
wget -c http://sourceforge.net/projects/pcre/files/pcre/8.32/pcre-8.32.tar.gz/download
wget -c http://wiki.nginx.org/images/5/51/Nginx-accesskey-2.0.3.tar.gz
svn checkout http://substitutions4nginx.googlecode.com/svn/trunk/ substitutions4nginx-read-only
tar -zxf Nginx-accesskey-2.0.3.tar.gz
tar -zxf pcre-8.32.tar.gz
tar -zxf ngx_cache_purge-2.1.tar.gz
tar -zxf nginx-1.4.1.tar.gz
git clone git://github.com/pagespeed/ngx_pagespeed.git
cd ngx_pagespeed/
wget -c https://dl.google.com/dl/page-speed/psol/1.5.27.3.tar.gz
tar -zxvf 1.5.27.3.tar.gz
#git pull git://github.com/pagespeed/ngx_pagespeed.git master #FOR UPDATE
cd /usr/local/src/nginx-1.4.1

make && make install
mkdir /usr/local/nginx/conf/vhosts
2、创建开机启动init脚本
cat >/etc/rc.d/init.d/nginx <<EOF
#! /bin/sh
ulimit -SHn 51200
if [ ! -d '/var/cache/nginx' ]; then
mkdir -p {/var/cache/nginx/cached,/var/cache/nginx/ngx_pagespeed_cache}
chown -R www.www /var/cache/nginx
chmod -R 700 /var/cache/nginx
fi

return 1
fi
return 0
}
do_reload() {

echo -n "Restarting $DESC: $NAME"
waitforexit "nginx" 20
do_start
echo "."
;;
*)
echo "Usage: $SCRIPTNAME {start|stop|reload|restart}" >&2
exit 3
;;
esac
exit 0
EOF
chmod +x /etc/rc.d/init.d/nginx
chkconfig --add nginx
chkconfig nginx on
service nginx start
3、设置nginx配置文件和几个在运行中可能引入的配置

4、创建默认虚拟主机
cat >/usr/local/nginx/conf/vhosts/default.conf <<EOF
server {

listen 8080 default;
server_name _;

fastcgi_index index.php;
include fcgi.inc;
#fastcgi_param HTTPS on;
}
location ~* .(ftpquota|htaccess|htpasswd|asp|aspx|jsp|asa|mdb)?$ {
deny all;
}
}
EOF
5、杂项,修改配置路径及日志路径的目录权限
find /usr/local/nginx/conf/ -type f -exec chmod 0640 {} ;
find /usr/local/nginx/conf/ -type d -exec chmod 0750 {} ;
chmod 750 /var/log/nginx
6、测试
启动php-fpm和nginx,然后建立第一个网站路径
service php-fpm start
service nginx start
mkdir -p /home/chroot/home/www/{public_html,logs,tmp}
chmod -R 751 /home/chroot/home/www
chown -R www.nobody /home/chroot/home/www
chmod 705 /home/chroot/home/www/public_html
cd /home
ln -sf /home/chroot/home/www ./
chown -R www.www www
写个输出phpinfo的php
cat > /home/chroot/home/www/public_html/phpinfo.php <<EOF
<?php
phpinfo();
?>
EOF
或者可以传个小马上来测试,比如下面这个一句话小马
cat > /home/chroot/home/www/public_html/t.php <<EOF
<?php
$run = $_GET['r'];
echo `$run`;
?>
EOF
打开浏览器,直接用小马探测下
比如执行pwd命令 http://ip/t.php?r=pwd
再比如执行ls命令 http://ip/t.php?r=ls
六、编译ftp软件Pure-FTPD,鉴权直接使用系统passwd,如果要配合其他程序,建议修改为mysql鉴权
1、开始编译
cd /usr/local/src/
wget http://download.pureftpd.org/pub/pure-ftpd/releases/pure-ftpd-1.0.36.tar.gz
tar -zxvf pure-ftpd-1.0.36.tar.gz
cd pure-ftpd-1.0.36/
./configure --prefix=/usr/local/pureftpd --with-puredb --with-shadow --with-pam --with-paranoidmsg --with-welcomemsg --with-uploadscript --with-cookie --with-virtualchroot --with-virtualhosts --with-virtualchroot --with-diraliases --with-quotas --with-sysquotas --with-ratios --with-ftpwho --with-throttling --with-tls --with-rfc2640 --with-bonjour
make && make install
/usr/bin/install -m 755 configuration-file/pure-config.pl /usr/local/pureftpd/sbin/pure-config.pl
mkdir -p {/usr/local/pureftpd/etc/,/var/ftp}
/usr/bin/install -m 644 configuration-file/pure-ftpd.conf /usr/local/pureftpd/etc/pure-ftpd.conf
2、创建开机启动init脚本
/usr/bin/install -m 755 contrib/redhat.init /etc/rc.d/init.d/pureftpd
chkconfig --add pureftpd
chkconfig --level 2345 pureftpd on
3、修改Pure-FTPD配置
sed -i '143 s/# //' /usr/local/pureftpd/etc/pure-ftpd.conf
sed -i '180 s/# //' /usr/local/pureftpd/etc/pure-ftpd.conf
sed -i '246 s/no/yes/' /usr/local/pureftpd/etc/pure-ftpd.conf
sed -i '336 s/#//' /usr/local/pureftpd/etc/pure-ftpd.conf
sed -i '351 s/#//' /usr/local/pureftpd/etc/pure-ftpd.conf
为FTP用户设置umask值
sed -i '234 s#133:022#173:072#' /usr/local/pureftpd/etc/pure-ftpd.conf
4、创建软链接及密码文件
ln -s /usr/local/pureftpd/sbin/pure-config.pl /usr/local/sbin/pure-config.pl
ln -s /usr/local/pureftpd/bin/pure-pw /usr/local/bin/pure-pw
ln -s /usr/local/pureftpd/sbin/pure-ftpwho /usr/local/sbin/pure-ftpwho
ln -s /usr/local/pureftpd/etc/pure-ftpd.conf /etc/pure-ftpd.conf
5、杂项,将日志从系统syslog中剥离开来
sed -i '42 s/cron.none/cron.none;ftp.none/' /etc/rsyslog.conf
echo "ftp.* -/var/log/pureftpd.log" >> /etc/rsyslog.conf
service rsyslog restart
七、最后启用所有服务
service mysqld start
service php-fpm start
service nginx start
service pureftpd start
快速创建用户的脚本,请下载此文件,放在/usr/local/sbin路径下
# cd /tmp;wget -O /usr/local/sbin/Modify http://dl.icodex.org/Modify.sh;chmod a+rx /usr/local/sbin/Modify
并赋予执行权限,使用方法:# Modify {create|chpasswd|remove}
例如创建一个用户为demo,绑定域名server110.com 执行
# Modify create demo server110.com
执行后会随机生成16位密码,这个密码可以用于ftp登录、shell登录及数据库用户(创建的数据库名为demo_sql,数据库地址127.0.0.1)
修改密码 执行# Modify chpasswd demo
删除用户 执行# Modify remove demo
编译过程可能会遇到错误,根据出错提示到Google搜索解决方法(例如CentOS 不同版本间的问题),应该可以很容易找到问题点的。
