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_thread_concurrency = 8

innodb_flush_log_at_trx_commit = 2

innodb_log_buffer_size = 16M

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"

(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）：

<?xml version="1.0" ?>

All relative paths in this config are relative to php's install prefix

Pid file

<value name="pid_file">/usr/local/webserver/php/logs/php-fpm.pid</value>

Error log file

<value name="error_log">/usr/local/webserver/php/logs/php-fpm.log</value>

Log level

<value name="log_level">notice</value>

... in a less than this interval of time, a graceful restart will be initiated.

Useful to work around accidental curruptions in accelerator's shared memory.

Time limit on waiting child's reaction on signals from master

Set to 'no' to debug fpm

</section>

Name of pool. Used in logs and stats.

<value name="name">default</value>

Valid values are 'static' and 'apache-like'

<value name="style">static</value>

Sets the limit on the number of simultaneous requests that will be served.

Equivalent to Apache MaxClients directive.

Equivalent to PHP_FCGI_CHILDREN environment in original php.fcgi

Used with any pm_style.

Settings group for 'apache-like' pm style

Sets the number of server processes created on startup.

Used only when 'apache-like' pm_style is selected

Sets the desired minimum number of idle server processes.

Used only when 'apache-like' pm_style is selected

Sets the desired maximum number of idle server processes.

Used only when 'apache-like' pm_style is selected

</value>

The timeout (in seconds) for serving a single request after which the worker process will be terminated

Should be used when 'max_execution_time' ini option does not stop script execution for some reason

'0s' means 'off'

The timeout (in seconds) for serving of single request after which a php backtrace will be dumped to slow.log file

'0s' means 'off'

The log file for slow requests

Set open file desc rlimit

Set max core size rlimit

Chroot to this directory at the start, absolute path

Chdir to this directory at the start, absolute path

Redirect workers' stdout and stderr into main error log.

If not set, they will be redirected to /dev/null, according to FastCGI specs

Useful to work around memory leaks in 3rd party libraries.

For endless request processing please specify 0

Equivalent to PHP_FCGI_MAX_REQUESTS

Comma separated list of ipv4 addresses of FastCGI clients that allowed to connect.

Equivalent to FCGI_WEB_SERVER_ADDRS environment in original php.fcgi (5.2.2+)

Makes sense only with AF_INET listening socket.

</value>

</section>

</workers>

</configuration>

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/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
