（1）删除Linux系统默认安装的web服务器软件包，如:httpd、mysql、php等，卸载可以用以下命令
[root@test.com~]#rpm -e httpd
[root@test.com~]#rpm -e php
[root@test.com~]#rpm -e mysql
（2）使用yum更新系统组件
[root@test.com~]#yum -y install yum-fastestmirror
[root@test.com~]#yum -y update
[root@test.com~]#yum -y install patch make gcc gcc-c++ gcc-g77 flex bison file
[root@test.com~]#yum -y install libtool libtool-libs autoconf kernel-devel
[root@test.com~]#yum -y install libjpeg libjpeg-devel libpng libpng-devel libpng10 libpng10-devel gd gd-devel
[root@test.com~]#yum -y install freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel
[root@test.com~]#yum -y install glib2 glib2-devel bzip2 bzip2-devel libevent libevent-devel
[root@test.com~]#yum -y install ncurses ncurses-devel curl curl-devel e2fsprogs
[root@test.com~]#yum -y install openssl openssl-devel vim-minimal nano sendmail
[root@test.com~]#yum -y install fonts-chinese gettext gettext-devel
[root@test.com~]#yum -y install ncurses-devel
[root@test.com~]#yum -y install gmp-devel pspell-devel
[root@test.com~]#yum -y install unzip
（3）准备安装需要使用的软件包，使用wget下载

>2.php-5.2.10-fpm-0.5.13
>3.sohusin-patch-5.2.10-0.9.7.patch.gz

nginx限制ip并发数，也是说限制同一个ip同时连接服务器的数量
1.添加limit_zone
这个变量只能在http使用
vi /usr/local/nginx/conf/nginx.conf
limit_zone one $remote_addr 10m;
2.添加limit_conn
这个变量可以在http, server, location使用
我只限制一个站点，所以添加到server里面
vi /usr/local/nginx/conf/host/gaojinbo.com.conf
limit_conn one 10;
3.重启nginx
killall -HUP nginx
nginx 限速模块
参考：
关于limit_zone：http://wiki.nginx.org/NginxHttpLimitZoneModule
关于limit_rate和limit_conn：http://wiki.nginx.org/NginxHttpCoreModule
nginx可以通过HTTPLimitZoneModule和HTTPCoreModule两个组件来对目录进行限速。
http {
limit_zone one $binary_remote_addr 10m;
server {
location /download/ {
limit_conn one 1;
limit_rate 300k;
}
}
}
limit_zone，是针对每个IP定义一个存储session状态的容器。这个示例中定义了一个10m的容器，按照32bytes/session，可以处理320000个session。
limit_conn one 1;
限制每个IP只能发起一个并发连接。
limit_rate 300k;
对每个连接限速300k. 注意，这里是对连接限速，而不是对IP限速。如果一个IP允许两个并发连接，那么这个IP就是限速limit_rate×2。
