CenOS 6.5系统下安装配置Nginx 1.2.4 + PHP 5.4.8 + MySQL 5.5.2-中存储网

2014-07-13 16:13:02 来源：中存储网

1. 修改 SSH 连接显示字符集（可以忽略这一步，偶尔出现乱码影响也不大的）

# vi /etc/profile

添加：

LANG=zh_CN.GB2312

export LANG

使环境变量生效保存后断开 SSH 重新连接

# source /etc/profile

注意：

如果有添加这一步，在设置 mysql 密码时会出现个 sql 编码问题，需要注释掉这里的设置断开ssh后重连就可以了

2. 设置时区

# cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

同步时间

# /usr/bin/rdate -s rdate.darkorb.net

写入 BIOS 避免失效

# hwclock -w

建议加入定时同步

# crontab -e

# 0 0 * * * /usr/bin/rdate -s rdate.darkorb.net

3. 配置服务器 yum 国内更新源地址

# cd /etc/yum.repos.d

# mv CentOS-Base.repo CentOS-Base.repo.bak

# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo

# yum makecache

4. 更新软件和安装依赖包

# sudo -s

# LANG=C

# yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers ntpd nmap patch cmake bison cgi* *-gd-* libtool-* gettext *libxml-devel libcurl-devel libevent libevent-devel net-snmp-devel lsof unzip

如果出现错误如：Error: Package: glibc-headers-2.12-1.80.el6_3.4.x86_64 (updates)

查看 http://www.zhouz.me/post/2012-10-25/40040279305

5. 设置路径

# vi /etc/ld.so.conf

添加：

/usr/lib/

/usr/local/lib/

/usr/lib64/

/usr/local/lib64/

6. 最好重启一次

# reboot

7. 开始安装 nginx

新建保存下载软件的目录

# mkdir -p /mydata/soft

# mkdir -p /var/www/html

# cd /mydata/soft/

下载：

# wget http://nginx.org/download/nginx-1.2.4.tar.gz

# wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.31.tar.gz

# wget https://gperftools.googlecode.com/files/gperftools-2.0.tar.gz

# wget http://download.savannah.gnu.org/releases/libunwind/libunwind-1.1.tar.gz

7.1 利用 TCMalloc 优化 nginx 性能

针对 64 位操作系统必须安装 libunwind 库

# tar zxvf libunwind-1.1.tar.gz

# cd libunwind-1.1/

# CFLAGS=-fPIC ./configure

# make CFLAGS=-fPIC

# make CFLAGS=-fPIC install

# cd ../

安装 google-perftools 优化

# tar zxvf gperftools-2.0.tar.gz

# cd gperftools-2.0/

# ./configure

# make && make install

# echo "/usr/local/lib" > /etc/ld.so.conf.d/usr_local_lib.conf

# /sbin/ldconfig

# cd ..

7.2 安装 pcre 使 nginx 支持 URL 重写

# tar zxvf pcre-8.31.tar.gz

# cd pcre-8.31

# ./configure

# make && make install

# cd ../

7.3 编译安装 nginx

# tar zxvf nginx-1.2.4.tar.gz

# cd nginx-1.2.4

# ./configure --prefix=/usr/local/nginx --with-google_perftools_module --user=www --group=www --with-http_stub_status_module --with-openssl=/usr/ --with-pcre=/mydata/soft/pcre-8.31

# make && make install

#cd ../

# mkdir /tmp/tcmalloc

# chmod 0777 /tmp/tcmalloc

7.4 添加用户和组

# /usr/sbin/groupadd www

# /usr/sbin/useradd -g www www

7.5 配置 nginx.conf

# vi /usr/local/nginx/conf/nginx.conf

注意：要在 pid 下一行添加下面的代码才能使优化生效

google_perftools_profiles /tmp/tcmalloc;

示例：替换为以下内容

user www www;

worker_processes 4;

worker_cpu_affinity 0001 0100 1000 0010;

error_log logs/error.log;

pid logs/nginx.pid;

worker_rlimit_nofile 65535;

google_perftools_profiles /tmp/tcmalloc;

events {

worker_connections 65535;

}

http {

#include deny_ips.conf;

include mime.types;

default_type application/octet-stream;

server_tokens off;

log_format main '$remote_addr - $remote_user [$time_local] "$request" '

'$status $body_bytes_sent "$http_referer" '

'"$http_user_agent" "$http_x_forwarded_for"';

#access_log logs/access.log main;

server_names_hash_bucket_size 128;

client_header_buffer_size 32k;

large_client_header_buffers 4 32k;

client_max_body_size 50m;

sendfile on;

tcp_nopush on;

tcp_nodelay on;

keepalive_timeout 60;

fastcgi_connect_timeout 300;

fastcgi_send_timeout 300;

fastcgi_read_timeout 300;

fastcgi_buffer_size 64k;

fastcgi_buffers 4 64k;

fastcgi_busy_buffers_size 128k;

fastcgi_temp_file_write_size 256k;

fastcgi_intercept_errors on;

gzip on;

gzip_min_length 1k;

gzip_buffers 4 16k;

gzip_http_version 1.0;

gzip_comp_level 2;

gzip_types text/plain application/x-javascript text/css application/xml;

gzip_vary on;

include vhost/*.conf;

}

7.6 启动 nginx

# ulimit -SHn 65535

# /usr/local/nginx/sbin/nginx

7.7 验证google-perftools是否已经正常加载命令:

# lsof -n | grep tcmalloc

显示如下：

nginx 2395 nobody 9w REG 8,8 0 1599440 /tmp/tcmalloc.2395

nginx 2396 nobody 11w REG 8,8 0 1599443 /tmp/tcmalloc.2396

nginx 2397 nobody 13w REG 8,8 0 1599441 /tmp/tcmalloc.2397

nginx 2398 nobody 15w REG 8,8 0 1599442 /tmp/tcmalloc.2398

由于在Nginx配置文件中，设置worker_processes的值为4，因此开启了4个Nginx线程，每个线程会有一行记录。每个线程文件后面的数字值就是启动的Nginx的PID值。

至此，利用TCMalloc优化Nginx的操作完成。

7.8 优化 nginx 内核

# vi /etc/sysctl.conf

末尾添加：

net.ipv4.tcp_max_tw_buckets = 6000

net.ipv4.ip_local_port_range = 1024 65000

net.ipv4.tcp_tw_recycle = 1

net.ipv4.tcp_tw_reuse = 1

net.ipv4.tcp_syncookies = 1

net.core.somaxconn = 262144

net.core.netdev_max_backlog = 262144

net.ipv4.tcp_max_orphans = 262144

net.ipv4.tcp_max_syn_backlog = 262144

net.ipv4.tcp_synack_retries = 1

net.ipv4.tcp_syn_retries = 1

net.ipv4.tcp_fin_timeout = 1

net.ipv4.tcp_keepalive_time = 30

刷新配置

# /sbin/sysctl -p

7.9 添加 nginx 的系统服务

之前在安装的时候写过了，详细内容可前往下面地址：

http://www.zhouz.me/post/2012-10-23/40041551802

7.10 添加各站点配置目录

# cd /usr/local/nginx/conf

# mkdir vhost

7.10.1 配置 localhost 站点

# vi vhost/localhost.conf

添加：

server

{

listen 80;

server_name localhost;

index index.html index.php;

root /var/www/html/;

#limit_conn crawler 20;

location ~ .*.(php|php5)?$

{

#fastcgi_pass unix:/tmp/php-cgi.sock;

#upload filesize limit

#client_max_body_size 10m;

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

include fastcgi.conf;

}

8. 安装 mysql

8.1 检测是否之前有安装过 rpm mysql包

查看系统是否有安装过 MySQL

注意大小写，如果mysql 不行就换MySQL

# rpm -qa | grep mysql

显示如：mysql-5.1.61-4.el6.x86_64

将搜索出的包名全部卸载：（nodeps表示强制删除），

例如：

# rpm -e --nodeps mysql-libs-5.1.61-4.el6.x86_64

8.2 下载 MySQL 相关软件包

# cd /mydata/soft

# wget http://www.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.28.tar.gz/from/http://cdn.mysql.com/

8.3 新建 MySQL 用户和组

# /usr/sbin/groupadd mysql

# /usr/sbin/useradd -g mysql mysql

8.4 新建目录并设置权限

# chmod +w /usr/local/mysql

# chown -R mysql:mysql /usr/local/mysql

# mkdir -p /var/mysql/data/

# mkdir -p /var/mysql/log/

# chown -R mysql:mysql /var/mysql/

# mkdir /home/mysql/temp

# chown -R mysql:mysql /home/mysql/temp

8.5 开始安装 MySQL

# tar xvf mysql-5.5.28.tar.gz

# cd mysql-5.5.28/

# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql

-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock

-DDEFAULT_CHARSET=utf8

-DDEFAULT_COLLATION=utf8_general_ci

-DWITH_EXTRA_CHARSETS:STRING=utf8,gbk

-DWITH_MYISAM_STORAGE_ENGINE=1

-DENABLED_LOCAL_INFILE=ON

-DWITH_INNOBASE_STORAGE_ENGINE=1

-DWITH_READLINE=1

-DENABLED_LOCAL_INFILE=1

-DMYSQL_USER=mysql

-DMYSQL_DATADIR=/var/mysql/data

# make && make install

8.6 配置 my.cnf 文件

# cd support-files/

注意：my-large.cnf 适用于1G内存左右的服务器，

可以根据自己配置情况选用 my-large.cnf 或 my-huge.cnf 等不同配置

# cp my-huge.cnf /etc/my.cnf

之前这里 my.cnf 的路径设置有问题（现已修改），导致没有生效，今天关闭 innodb 时才发现。。

是放在 etc 下面才会生效的。。

参考配置：关闭 innodb，binlog 保存 30 天内的

# vi /etc/my.cnf

--datadir=/var/mysql/data

--user=mysql

8.8 将 mysql 加入开机启动

# chmod +x /etc/init.d/mysqld

# vi /etc/init.d/mysqld

查找并修改：

basedir=/usr/local/mysql

datadir=/var/mysql/data

8.9 添加为系统服务

# chkconfig --add mysqld

# chkconfig --level 2345 mysqld on

8.10 启动mysql 设置 root 密码

# service mysqld start

# /usr/local/mysql/bin/mysqladmin -u root password "123456"

错误一：

mysqladmin, mysql ... 命令无法执行：

# export PATH=/usr/local/mysql/bin:$PATH

错误二：

Could NOT find Curses (missing: CURSES_LIBRARY CURSES_INCLUDE_PATH)

# yum install ncurses-devel

8.11 添加并发优化

# vi /usr/local/mysql/bin/mysqld_safe

在 executing mysqld_safe 的下一行，加上：

export LD_PRELOAD=/usr/local/lib/libtcmalloc.so

启动 mysql：

# service mysqld restart

使用lsof命令查看tcmalloc是否起效：

# /usr/sbin/lsof -n | grep tcmalloc

如果发现以下信息，说明tcmalloc已经起效：

mysqld 10847 mysql mem REG 8,5 1203756 20484960 /usr/local/lib/libtcmalloc.so.0.0.0

9.7 安装 PHP 扩展

9.7.1 服务器版 memcached

memcached 把我搞晕了，有两个 memcached，我也不是很清楚具体区别，

按我的理解应该是分为服务器版和 php 扩展版

一开始用服务器版来编译 php 扩展，搞了半天都没弄出来，后来才发现居然有两个，晕死了

安装依赖包：

# tar zxvf libevent-2.0.20-stable.tar.gz

# cd libevent-2.0.20-stable

# ./configure --prefix=/usr/local/libevent

# make && make install

# cd ../

# tar xvzf memcached-1.4.15.tar.gz

# cd memcached-1.4.15

# ./configure --enable-64bit --enable-threads --with-libevent=/usr/local/libevent

# make && make install

# cd ../

检测是否安装成功：

# ls -al /usr/local/bin/memcached

# mkdir -p /var/run/memcached/

启动 memcached：

# /usr/local/bin/memcached -d -m 128 -u root -l 22.11.5.91 -p 11211 -c 256 -P /var/run/memcached/memcached.pid

# ps aux|grep memcached

关闭 memcached：

# kill `cat /var/run/memcached/memcached.pid`

新建启动和关闭脚本并赋执行权限：

# cp memcached-1.4.15/scripts/memcached.sysv /etc/init.d/memcached

# chmod 755 /etc/init.d/memcached

修改配置：

# vi /etc/init.d/memcached

修改：

PORT=11212

USER=root

OPTIONS=""

查找：

daemon memcached -d -p ....

修改为：

daemon /usr/local/bin/memcached -d -p ....

添加下面两行：

chown $USER /usr/local/bin/memcached

/usr/local/bin/memcached -d -p $PORT -u $USER -m $CACHESIZE -c $MAXCONN -P /var/run/memcache/memcached.pid $OPTIONS

添加到系统服务：

# chkconfig --add memcached

# chkconfig --level 2345 memcached on

# chkconfig --list memcached

测试启动检测关闭：

# service memcached start

# ps aux|grep memcached

# service memcached stop

开启防火墙外网访问（单机可忽略该设置）：
