一、准备所需要的环境包组“Development tools”和“Server Platform Development”

#yum groupinstall "Development tools""Server Platform Development"

二、安装nginx

1、编译安装
# yum -y install pcre-devel
#tar xf nginx-1.4.2.tar.gz -C /usr/local/
#cd /usr/local/nginx-1.4.2
# groupadd -r nginx
# useradd -r -g nginx nginx

# ./configure \
 --prefix=/usr \                 #指定nginx的安装路径
 --sbin-path=/usr/sbin/nginx \    #指定sbin的路径
 --conf-path=/etc/nginx/nginx.conf \#conf的路径
 --error-log-path=/var/log/nginx/error.log \ #错误日志路径
 --http-log-path=/var/log/nginx/access.log \ #指定访问日志路径
 --pid-path=/var/run/nginx/nginx.pid \ #指定pid路径
 --lock-path=/var/lock/nginx.lock \    #指定锁文件路径
 --user=nginx \           #以nginx用户身份
 --group=nginx \          #以nginx组身份
 --with-http_ssl_module \
 --with-http_flv_module \
 --with-http_stub_status_module \
 --with-http_gzip_static_module \
 --http-client-body-temp-path=/var/tmp/nginx/client/ \
 --http-proxy-temp-path=/var/tmp/nginx/proxy/ \
 --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ \
 --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi \
 --http-scgi-temp-path=/var/tmp/nginx/scgi \
 --with-pcre
编译过程中如果提示我们还需要依赖某个包时，我们要安装对应的devel包

 # make && make install

4、为nginx提供SysV init脚本/etc/rc.d/init.d/nginx

#!/bin/sh
# nginx - this script starts and stops the nginx daemon
# chkconfig: - 85 15 
# description: Nginx is an HTTP(S) server, HTTP(S) reverse \
# proxy and IMAP/POP3 proxy server
# processname: nginx
# config: /etc/nginx/nginx.conf
# config: /etc/sysconfig/nginx
# pidfile: /var/run/nginx.pid
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0
nginx="/usr/sbin/nginx"
prog=$(basename $nginx)
NGINX_CONF_FILE="/etc/nginx/nginx.conf"
[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
lockfile=/var/lock/subsys/nginx

make_dirs() {
 # make required directories
 user=`nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=\([^ ]*\).*/\1/g' -`
 options=`$nginx -V 2>&1 | grep 'configure arguments:'`
 for opt in $options; do
 if [ `echo $opt | grep '.*-temp-path'` ]; then
 value=`echo $opt | cut -d "=" -f 2`
 if [ ! -d "$value" ]; then
 # echo "creating" $value
 mkdir -p $value && chown -R $user $value
 fi
 fi
 done
}

start() {
 [ -x $nginx ] || exit 5
 [ -f $NGINX_CONF_FILE ] || exit 6
 make_dirs
 echo -n $"Starting $prog: "
 daemon $nginx -c $NGINX_CONF_FILE
 retval=$?
 echo
 [ $retval -eq 0 ] && touch $lockfile
 return $retval
}

stop() {
 echo -n $"Stopping $prog: "
 killproc $prog -QUIT
 retval=$?
 echo
 [ $retval -eq 0 ] && rm -f $lockfile
 return $retval
}

restart() {
 configtest || return $?
 stop
 sleep 1
 start
}
reload() {
 configtest || return $?
 echo -n $"Reloading $prog: "
 killproc $nginx -HUP
 RETVAL=$?
 echo
}

force_reload() {
 restart
}

configtest() {
 $nginx -t -c $NGINX_CONF_FILE
}

rh_status() {
 status $prog
}

rh_status_q() {
 rh_status >/dev/null 2>&1
}

case "$1" in
 start)
 rh_status_q && exit 0
 $1
 ;;
 stop)
 rh_status_q || exit 0
 $1
 ;;
 restart|configtest)
 $1
 ;;
 reload)
 rh_status_q || exit 7
 $1
 ;;
 force-reload)
 force_reload
 ;;
 status)
 rh_status
 ;;
 condrestart|try-restart)
 rh_status_q || exit 0
 ;;
 *)
 echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
 exit 2
esac

# chmod +x /etc/rc.d/init.d/nginx
 # chkconfig --add nginx
 # chkconfig nginx on
 # service nginx start

三、安装mysql

1：分区格式化挂载

#fdisk /dev/sda      #创建磁盘分区  
#pvcreate /dev/sda{3,5}      #创建物理分区
#vgcreate myvg /dev/sda{3,5}     #创建卷组为myvg
#lvcreate -L 20G -n mydata myvg   #创建逻辑卷mydat
#mke2fs -t ext4 -L MYDATA -b 2048 /dev/myvg/mydata
#mkdir /mydata
cat /etc/fstab
LABEL=MYDATA /mydata  ext4 defaults 0 0

#mount -a
#mkdir /mydata/data

2：解压安装

#useradd -r mysql
#chown -R mysql:mysql /mydata/data
#tar xf mysql-5.5.33-linux2.6-x86_64.tar.gz -C /usr/local
#cd /usr/local/
#ln -sv mysql-5.5.33-linux2.6-x86_64 mysql
#chown -R root:mysql /usr/local/mysql/*
#cd mysql/support-files           #有样例，我们可以根据自己的需要选择
#cp my-large.cnf /etc/my.cnf

3：修改配置文件/etc/my.cnf

找到相关设置进行修改操作

thread_concurrency = 4 #并发核心数，如果物理核心为2，这里就可以填写4

datadir = /mydata/data

innodb_file_per_table = 1 #每表一个表空间

#cp mysql.server /etc/rc.d/init.d/mysqld
 #chmod +x /etc/rc.d/init.d/mysqld
 #cd /usr/local/mysql/
 #scripts/mysql_install_db --user=mysql --datadir=/mydata/data/       #初始化成功
 #chkconfig --add mysqld
 #service mysqld start
 # vim /etc/profile.d/mysql.sh
export PATH=/usr/local/mysql/bin:$PATH
 # . /etc/profile.d/mysql.sh       #执行后就可以连mysql了

4：因为我们的安装不在标准路径下，所以还要导出相关文件

#vim /etc/man.config               #导出帮助文件
MANPATH /usr/local/mysql/man
 #ln -sv /usr/local/mysql/include /usr/local/mysql
 #vim /etc/ld.so.conf.d/mysql.conf
/usr/local/mysql/lib

 #mysql
 #mysql> use mysql
 mysql> select user,host,password from user;     #查看有哪些用户
 mysql> drop user ''@localhost;                 #删除不安全的用户
 mysql> update user set password=PASSWORD('mypass')where user='root';  
 mysql> flush privileges;            #刷新授权表

四、安装php-fpm

1、php-5.4.19.tar.bz2

# tar xf php-5.4.19.tar.bz2
 # cd php-5.4.19
 # ./configure --prefix=/usr/local/php --with-mysql=/usr/local/mysql --with-openssl --enable-fpm --enable-sockets --enable-sysvshm --with-mysqli=/usr/local/mysql/bin/mysql_config --enable-mbstring --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib-dir --with-libxml-dir=/usr --enable-xml --with-mhash --with-mcrypt --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --with-bz2 --with-curl 
 #make && make install

2、为php提供配置文件：

# cp php.ini-production /etc/php.ini
 # cp sapi/fpm/init.d.php-fpm /etc/rc.d/init.d/php-fpm
 # chmod +x /etc/rc.d/init.d/php-fpm
 # chkconfig --add php-fpm
 # chkconfig php-fpm on
 # cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf

编辑php-fpm的配置文件：

# vim /usr/local/php/etc/php-fpm.conf

pm.max_children = 150
pm.start_servers = 8
pm.min_spare_servers = 5
pm.max_spare_servers = 10
pid = /usr/local/php/var/run/php-fpm.pid

接下来就可以启动php-fpm了：

# service php-fpm start

# ps aux | grep php-fpm

服务脚本启动时没有OK字样我么可以编辑服务脚本，在其中加入这么两行

[ -f /etc/rc.d/init.d/functions ] && . /etc/rc.d/init.d/functions # 脚本首行

daemon $php_fpm_BIN --daemonize $php_opts

#service php-fpm restart #重新启动php-fpm

五、整合nginx和php-fpm

1、#vim /etc/nginx/nginx.conf，启用如下选项：

location ~ \.php$ {

root html;

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;

include fastcgi_params;

}

并在所支持的主页面格式中添加php格式的主页，类似如下：

location / {

root html;

index index.php index.html index.htm;

}

2、编辑/etc/nginx/fastcgi_params，将其内容更改为如下内容：

fastcgi_param GATEWAY_INTERFACE CGI/1.1;

fastcgi_param SERVER_SOFTWARE nginx;

fastcgi_param QUERY_STRING $query_string;

fastcgi_param REQUEST_METHOD $request_method;

fastcgi_param CONTENT_TYPE $content_type;

fastcgi_param CONTENT_LENGTH $content_length;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

fastcgi_param SCRIPT_NAME $fastcgi_script_name;

fastcgi_param REQUEST_URI $request_uri;

fastcgi_param DOCUMENT_URI $document_uri;

fastcgi_param DOCUMENT_ROOT $document_root;

fastcgi_param SERVER_PROTOCOL $server_protocol;

fastcgi_param REMOTE_ADDR $remote_addr;

fastcgi_param REMOTE_PORT $remote_port;

fastcgi_param SERVER_ADDR $server_addr;

fastcgi_param SERVER_PORT $server_port;

fastcgi_param SERVER_NAME $server_name;

而后重新载入nginx的配置文件：

# service nginx reload

3、在/usr/html新建index.php的测试页面

<?php

phpinfo();

然后通过浏览器访问此测试页面

六、安装xcache （为php进行加速）

1、xcache-3.0.3.tar.bz2

# tar xfxcache-3.0.3.tar.bz2
 #cd xcache-3.0.3
 # /usr/local/php/bin/phpize
 # ./configure --enable-xcache --with-php-config=/usr/local/php/bin/php-config
 # make && make install

安装结束时，会出现类似如下行：

Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-zts-20100525/

2、整合php和xcache

首先将xcache提供的样例配置导入php.ini

# mkdir /etc/php.d

# cp xcache.ini /etc/php.d

#vim /etc/php.d/xcache.ini

找到extension开头的行，修改为如下行：

注意：如果php.ini文件中有多条extension指令行，要确保此新增的行排在第一位。

3、重新启动php-fpm

# service php-fpm restart

可以通过别的虚拟机对我们配置的服务进行压力测试,就能体会到php加速器的效果了
