wget http://blog.s135.com/soft/linux/nginx_php/imagick/imagick-2.3.0.tgz

三.安装PHP 5.2.14(FastCGI模式)

1.编译安装 PHP 5.2.14所需的支持库

tar zxvf libiconv-1.13.1.tar.gz

cd libiconv-1.13.1/

./configure --prefix=/usr/local

make

make install

cd ../

tar zxvf libmcrypt-2.5.8.tar.gz

cd libmcrypt-2.5.8/

./configure

make

make install

/sbin/ldconfig

cd libltdl/

./configure --enable-ltdl-install

make

make install

cd ../../

tar zxvf mhash-0.9.9.9.tar.gz

cd mhash-0.9.9.9/

./configure

make

make install

cd ../

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

ln -s /usr/local/bin/libmcrypt-config /usr/bin/libmcrypt-config

tar zxvf mcrypt-2.6.8.tar.gz

cd mcrypt-2.6.8/

/sbin/ldconfig

./configure

make

make install

cd ../

2.编译安装MySQL 5.5.3-m3

(1)

/usr/sbin/groupadd mysql

/usr/sbin/useradd -g mysql mysql

tar zxvf mysql-5.5.3-m3.tar.gz

cd mysql-5.5.3-m3/

./configure --prefix=/usr/local/webserver/mysql/ --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile --with-plugins=partition,innobase,myisammrg

make && make install

chmod +w /usr/local/webserver/mysql

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

cd ../

(2) 创建MySQL数据库存放目录

mkdir  -p /media/raid10/mysql/3306/data/

mkdir  -p /media/raid10/mysql/3306/binlog/

mkdir  -p /media/raid10/mysql/3306/relaylog/

chown  -R mysql:mysql  /media/raid10/mysql/

注意:因为要存放数据库文件,所以我把 这些文件,存放在 RAID10的设备上

实现 软RAID10,可以查看之前的文章共三篇

http://blog.csdn.net/longxibendi/archive/2011/04/20/6336912.aspx

http://blog.csdn.net/longxibendi/archive/2011/04/20/6336921.aspx

http://blog.csdn.net/longxibendi/archive/2011/04/20/6336947.aspx

(3).以mysql用户帐号的身份建立数据表

/usr/local/webserver/mysql/bin/mysql_install_db --basedir=/usr/local/webserver/mysql --datadir=/media/raid10/mysql/3306/data --user=mysql

(4).创建my.cnf配置文件

vi /media/raid10/mysql/3306/my.cnf

[client]

character-set-server = utf8

port    = 3306

socket  = /tmp/mysql.sock

[mysqld]

character-set-server = utf8

replicate-ignore-db = mysql

replicate-ignore-db = test

replicate-ignore-db = information_schema

user    = mysql

port    = 3306

socket  = /tmp/mysql.sock

basedir = /usr/local/webserver/mysql

datadir = /media/raid10/mysql/3306/data

log-error = /media/raid10/mysql/3306/mysql_error.log

pid-file = /media/raid10/mysql/3306/mysql.pid

open_files_limit    = 10240

back_log = 600

max_connections = 5000

max_connect_errors = 6000

table_cache = 614

external-locking = FALSE

max_allowed_packet = 16M

sort_buffer_size = 1M

join_buffer_size = 1M

thread_cache_size = 300

#thread_concurrency = 8

query_cache_size = 20M

query_cache_limit = 2M

query_cache_min_res_unit = 2k

default-storage-engine = MyISAM

thread_stack = 192K

transaction_isolation = READ-COMMITTED

tmp_table_size = 20M

max_heap_table_size = 20M

long_query_time = 3

log-slave-updates

log-bin = /media/raid10/mysql/3306/binlog/binlog

binlog_cache_size = 4M

binlog_format = MIXED

max_binlog_cache_size = 8M

max_binlog_size = 20M

relay-log-index = /media/raid10/mysql/3306/relaylog/relaylog

relay-log-info-file = /media/raid10/mysql/3306/relaylog/relaylog

relay-log = /media/raid10/mysql/3306/relaylog/relaylog

expire_logs_days = 30

key_buffer_size = 10M

read_buffer_size = 1M

read_rnd_buffer_size = 6M

bulk_insert_buffer_size = 4M

myisam_sort_buffer_size = 8M

myisam_max_sort_file_size = 20M

myisam_repair_threads = 1

myisam_recover

interactive_timeout = 120

wait_timeout = 120

skip-name-resolve

#master-connect-retry = 10

slave-skip-errors = 1032,1062,126,1114,1146,1048,1396

#master-host     =   192.168.1.2

#master-user     =   username

#master-password =   password

#master-port     =  3306

server-id = 1

innodb_additional_mem_pool_size = 16M

innodb_buffer_pool_size = 20M

innodb_data_file_path = ibdata1:56M:autoextend

innodb_file_io_threads = 4

innodb_log_file_size = 20M

innodb_log_files_in_group = 3

innodb_max_dirty_pages_pct = 90

innodb_lock_wait_timeout = 120

innodb_file_per_table = 0

#log-slow-queries = /media/raid10/mysql/3306/slow.log

#long_query_time = 10

[mysqldump]

quick

max_allowed_packet = 32M

注意:由于用的虚拟机,只分配了512M内存,所以,相应的参数配置的很小。根据自己需求配置

(5).创建一个shell脚本,管理MySQL

vi  /media/raid10/mysql/3306/mysql

输入以下内容(这里的用户名是admin 密码是 12345678 ,接下来会创建这个用户并授权)

#!/bin/sh

mysql_port=3306

mysql_username="admin"

mysql_password="12345678"

function_start_mysql()

{

printf "Starting MySQL.../n"

/bin/sh /usr/local/webserver/mysql/bin/mysqld_safe --defaults-file=/media/raid10/mysql/${mysql_port}/my.cnf 2>&1 > /dev/null &

}

function_stop_mysql()

{

printf "Stoping MySQL.../n"

/usr/local/webserver/mysql/bin/mysqladmin -u ${mysql_username} -p${mysql_password} -S /tmp/mysql.sock shutdown

}

function_restart_mysql()

{

printf "Restarting MySQL.../n"

function_stop_mysql

sleep 5

function_start_mysql

}

function_kill_mysql()

{

kill -9 $(ps -ef | grep 'bin/mysqld_safe' | grep ${mysql_port} | awk '{printf $2}')

kill -9 $(ps -ef | grep 'libexec/mysqld' | grep ${mysql_port} | awk '{printf $2}')

}

if [ "$1" = "start" ]; then

function_start_mysql

elif [ "$1" = "stop" ]; then

function_stop_mysql

elif [ "$1" = "restart" ]; then

function_restart_mysql

elif [ "$1" = "kill" ]; then

function_kill_mysql

else

printf "Usage: /media/raid10/mysql/${mysql_port}/mysql {start|stop|restart|kill}/n"

fi

(6).赋予shell脚本 mysql 执行权限

chmod +x /media/raid10/mysql/3306/mysql

(7).启动MySQL

/media/raid10/mysql/3306/mysql start

(8).通过以下命令登录管理MySQL服务器(提示输入密码直接回车,这是用root登录的)

/usr/local/webserver/mysql/bin/mysql -u root -p -S /tmp/mysql.sock

(9).输入以下SQL语句,用于创建一个具有root权限的用户 ,用户名是 上面提到的 admin 密码  是 12345678    

GRANT ALL PRIVILEGES ON *.* TO 'admin'@'localhost' IDENTIFIED BY '12345678';

GRANT ALL PRIVILEGES ON *.* TO 'admin'@'127.0.0.1' IDENTIFIED BY '12345678';

因为接下来要安装wordpress,所以最好再加一条

GRANT ALL PRIVILEGES ON *.* TO 'admin'@'172.29.141.112' IDENTIFIED BY '12345678';

注意:

这里的 172.29.141.112 是允许 连接 MySQL服务器的客户端IP地址 ;

*.* 表示 所有 库和所有表   比如  blog.wordpress  表示 blog库的wordpress表

最后再加上

flush privileges ;

(10).停止 MySQL  (可选)

/media/raid10/mysql/3306/mysql stop

或者用 root 停止

3.编译安装PHP(FastCGI模式)

tar zxvf php-5.2.14.tar.gz

gzip -cd php-5.2.14-fpm-0.5.14.diff.gz | patch -d php-5.2.14 -p1

cd php-5.2.14/

./configure --prefix=/usr/local/webserver/php --with-config-file-path=/usr/local/webserver/php/etc --with-mysql=/usr/local/webserver/mysql --with-mysqli=/usr/local/webserver/mysql/bin/mysql_config --with-iconv-dir=/usr/local --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-discard-path --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-fastcgi --enable-fpm --enable-force-cgi-redirect --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-ldap --with-ldap-sasl --with-xmlrpc --enable-zip --enable-soap

make ZEND_EXTRA_LIBS='-liconv'

make install

cp php.ini-dist /usr/local/webserver/php/etc/php.ini

cd ../

4.编译安装PHP5扩展模块

tar zxvf memcache-2.2.5.tgz

cd memcache-2.2.5/

/usr/local/webserver/php/bin/phpize

./configure --with-php-config=/usr/local/webserver/php/bin/php-config

make

make install

cd ../

tar jxvf eaccelerator-0.9.6.1.tar.bz2

cd eaccelerator-0.9.6.1/

/usr/local/webserver/php/bin/phpize

./configure --enable-eaccelerator=shared --with-php-config=/usr/local/webserver/php/bin/php-config

make

make install

cd ../

tar zxvf PDO_MYSQL-1.0.2.tgz

cd PDO_MYSQL-1.0.2/

/usr/local/webserver/php/bin/phpize

./configure --with-php-config=/usr/local/webserver/php/bin/php-config --with-pdo-mysql=/usr/local/webserver/mysql

make

make install

cd ../

tar zxvf ImageMagick.tar.gz

cd ImageMagick-6.5.1-2/

./configure

make

make install

cd ../

tar zxvf imagick-2.3.0.tgz

cd imagick-2.3.0/

/usr/local/webserver/php/bin/phpize

./configure --with-php-config=/usr/local/webserver/php/bin/php-config

make

make install

cd ../

5.修改php.ini文件

手工修改:查找/usr/local/webserver/php/etc/php.ini中的extension_dir = "./"

  修改为extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"

  并在此行后增加以下几行,然后保存:

  extension = "memcache.so"

  extension = "pdo_mysql.so"

  extension = "imagick.so"

再查找output_buffering = Off

  修改为output_buffering = On

再查找; cgi.fix_pathinfo=0

  修改为cgi.fix_pathinfo=0,防止Nginx文件类型错误解析漏洞。

自动修改:若嫌手工修改麻烦,可执行以下shell命令,自动完成对php.ini文件的修改:

sed -i 's#extension_dir = "./"#extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"/nextension = "memcache.so"/nextension = "pdo_mysql.so"/nextension = "imagick.so"/n#' /usr/local/webserver/php/etc/php.ini

sed -i 's#output_buffering = Off#output_buffering = On#' /usr/local/webserver/php/etc/php.ini

sed -i "s#; always_populate_raw_post_data = On#always_populate_raw_post_data = On#g" /usr/local/webserver/php/etc/php.ini

sed -i "s#; cgi.fix_pathinfo=0#cgi.fix_pathinfo=0#g" /usr/local/webserver/php/etc/php.ini

6.配置eAccelerator加速PHP:

mkdir -p /usr/local/webserver/eaccelerator_cache

vi /usr/local/webserver/php/etc/php.ini

按shift+g键跳到配置文件的最末尾,加上以下配置信息:

[eaccelerator]

zend_extension="/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"

eaccelerator.shm_size="64"

eaccelerator.cache_dir="/usr/local/webserver/eaccelerator_cache"

eaccelerator.enable="1"

eaccelerator.optimizer="1"

eaccelerator.check_mtime="1"

eaccelerator.debug="0"

eaccelerator.filter=""

eaccelerator.shm_max="0"

eaccelerator.shm_ttl="3600"

eaccelerator.shm_prune_period="3600"

eaccelerator.shm_only="0"

eaccelerator.compress="1"

eaccelerator.compress_level="9"

7.创建www用户和组,以及供blog虚拟主机使用的目录:

/usr/sbin/groupadd www

/usr/sbin/useradd -g www www

mkdir  -p  /media/raid10/htdocs/blog

chmod  +w  /media/raid10/htdocs/blog

chown  -R  www:www /media/raid10/htdocs/blog

mkdir  -p  /media/raid10/htdocs/www

chmod  +w  /media/raid10/htdocs/www

chown  -R  www:www /media/raid10/htdocs/www

8.创建php-fpm配置文件(php-fpm是为PHP打的一个FastCGI管理补丁,可以平滑变更php.ini配置而无需重启php-cgi):

  在/usr/local/webserver/php/etc/目录中创建php-fpm.conf文件:

rm -f /usr/local/webserver/php/etc/php-fpm.conf

vi /usr/local/webserver/php/etc/php-fpm.conf

输入以下内容(如果您安装 Nginx + PHP 用于程序调试,请将以下的<value name="display_errors">0</value>改为<value name="display_errors">1</value>,以便显示PHP错误信息,否则,Nginx 会报状态为500的空白错误页):

9.启动php-cgi进程,监听127.0.0.1的9000端口,进程数为128(如果服务器内存小于3GB,可以只开启64个进程),用户为www:

ulimit -SHn 65535

/usr/local/webserver/php/sbin/php-fpm start

注意:/usr/local/webserver/php/sbin/php-fpm还有其他参数,包括:start|stop|quit|restart|reload|logrotate,修改php.ini后不重启php-cgi,重新加载配置文件使用reload。

四.安装Nginx 0.8.46

1.安装Nginx所需的pcre库:

tar zxvf pcre-8.10.tar.gz

cd pcre-8.10/

./configure

make && make install

cd ../

2.安装Nginx

tar zxvf nginx-0.8.46.tar.gz

cd nginx-0.8.46/

./configure --user=www --group=www --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module

make && make install

cd ../

3.创建Nginx日志目录

}

(2).在/usr/local/webserver/nginx/conf/目录中创建fcgi.conf文件:

vi /usr/local/webserver/nginx/conf/fcgi.conf

输入以下内容:

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;

fastcgi_param  SERVER_SOFTWARE    nginx;

fastcgi_param  SERVER_NAME        $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect

fastcgi_param  REDIRECT_STATUS    200;

5.启动Nginx

ulimit -SHn 65535

/usr/local/webserver/nginx/sbin/nginx

五.配置开机自动启动Nginx + PHP

vi /etc/rc.local

在末尾增加以下内容:

ulimit -SHn 65535

/usr/local/webserver/php/sbin/php-fpm start

/usr/local/webserver/nginx/sbin/nginx

六.优化Linux内核参数

具体参考http://blog.csdn.net/longxibendi/archive/2011/04/23/6343686.aspx

vi  /etc/sysctl.conf

# http://blog.csdn.net/longxibendi/archive/2011/04/23/6343686.aspx

net.ipv4.tcp_max_syn_backlog = 65536

net.core.netdev_max_backlog =  32768

net.core.somaxconn = 32768

net.core.wmem_default = 8388608

net.core.rmem_default = 8388608

net.core.rmem_max = 16777216

net.core.wmem_max = 16777216

net.ipv4.tcp_timestamps = 0

net.ipv4.tcp_synack_retries = 2

net.ipv4.tcp_syn_retries = 2

net.ipv4.tcp_tw_recycle = 1

#net.ipv4.tcp_tw_len = 1

net.ipv4.tcp_tw_reuse = 1

net.ipv4.tcp_mem = 94500000 915000000 927000000

net.ipv4.tcp_max_orphans = 3276800

#net.ipv4.tcp_fin_timeout = 30

#net.ipv4.tcp_keepalive_time = 120

net.ipv4.ip_local_port_range = 1024  65535

#http://blog.csdn.net/longxibendi/archive/2011/04/23/6343686.aspx 

使配置立即生效:

/sbin/sysctl -p

七.在不停止Nginx服务的情况下平滑变更Nginx配置

  1.修改/usr/local/webserver/nginx/conf/nginx.conf配置文件后,请执行以下命令检查配置文件是否正确:

/usr/local/webserver/nginx/sbin/nginx -t

如果屏幕显示以下两行信息,说明配置文件正确:

  the configuration file /usr/local/webserver/nginx/conf/nginx.conf syntax is ok

  the configuration file /usr/local/webserver/nginx/conf/nginx.conf was tested successfully

  2.平滑重启:

  (1)对于Nginx 0.8.x版本,现在平滑重启Nginx配置非常简单,执行以下命令即可:

/usr/local/webserver/nginx/sbin/nginx -s reload

(2)对于Nginx 0.8.x之前的版本,平滑重启稍微麻烦一些,按照以下步骤进行即可。输入以下命令查看Nginx主进程号:

ps -ef | grep "nginx: master process" | grep -v "grep" | awk -F ' ' '{print $2}'

屏幕显示的即为Nginx主进程号,例如:

  6302

  这时,执行以下命令即可使修改过的Nginx配置文件生效:

kill -HUP 6302

或者无需这么麻烦,找到Nginx的Pid文件:

kill -HUP `cat /usr/local/webserver/nginx/nginx.pid`

或者

ps -ef | grep nginx | grep -v grep | xargs kill {}/;

或者

kill  1  `cat /usr/local/webserver/nginx/nginx.pid`

八.编写每天定时切割Nginx日志的脚本

  1、创建脚本/usr/local/webserver/nginx/sbin/cut_nginx_log.sh

vi /usr/local/webserver/nginx/sbin/cut_nginx_log.sh

输入以下内容:

引用

#!/bin/bash

# This script run at 00:00

# The Nginx logs path

logs_path="/usr/local/webserver/nginx/logs/"

mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/

mv ${logs_path}access.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/access_$(date -d "yesterday" +"%Y%m%d").log

kill -USR1 `cat /usr/local/webserver/nginx/nginx.pid`

2、设置crontab,每天凌晨00:00切割nginx访问日志

crontab -e

输入以下内容:

引用

00 00 * * * /bin/bash  /usr/local/webserver/nginx/sbin/cut_nginx_log.sh

九.安装 wordpress

(1)下载 

cd /home/root/data1

wget http://cn.wordpress.org/wordpress-3.1.1-zh_CN.tar.gz

(2)解压 、赋权

tar zxvf wordpress-3.1.1-zh_CN.tar.gz  -C  /media/raid10/htdocs/blog/

chmod 777 -R /media/raid10/htdocs/blog/

(3)创建数据库

/usr/local/webserver/mysql/bin/mysql -u admin -p -S /tmp/mysql.sock

(注意密码是 12345678)

MySQL>create database blog;

MySQL>flush privileges;

(4)修改 wp-config-sample.php

mv /media/raid10/htdocs/blog/wordpress/wp-config-sample.php   /media/raid10/htdocs/blog/wordpress/wp-config.php

vi /media/raid10/htdocs/blog/wordpress/wp-config.php  修改数据库名,用户,密码,数据库IP

比如我的修改后的文件部分内容是

// ** MySQL 设置 - 具体信息来自您正在使用的主机 ** //

/** WordPress 数据库的名称 */

define('DB_NAME', 'blog');

/** MySQL 数据库用户名 */

define('DB_USER', 'admin');

/** MySQL 数据库密码 */

define('DB_PASSWORD', '12345678');

/** MySQL 主机 */

define('DB_HOST', '172.29.141.112');

注意:这里的DB_HOST对应的IP是,安装数据库的系统IP

(5)安装,运行 install.php

http://172.29.141.112/wordpress/install.php

或者  http://172.29.141.112/wordpress/wp-admin/install.php

根据前面设置的用户名和密码安装即可

然后就可以访问 http://172.29.141.112/wordpress/  了,

注意 :  如果想让非本机用户访问 需要打开防火墙 http服务 。默认只允许 SSH服务
