（即--php）服务器一直是被认为性能高，内存占用少的服务器，下面我们来介绍怎么通过简单的YUM命令安装，当然，你也可以试下。
导入第三方软件库
5 32位：
rpm -Uvh http://nginx.org/packages/centos/5/noarch/RPMS/nginx-release-centos-5-0.el5.ngx.noarch.rpm
rpm -Uvh http://centos.alt.ru/repository/centos/5/i386/centalt-release-5-3.noarch.rpm
centos 5 64位：
rpm -Uvh http://nginx.org/packages/centos/5/noarch/RPMS/nginx-release-centos-5-0.el5.ngx.noarch.rpm
rpm -Uvh http://centos.alt.ru/repository/centos/5/x86_64/centalt-release-5-3.noarch.rpm
安装mysql
1、先卸载系统自带的，然后更新软件库
yum remove httpd
yum update
2、yum安装mysql
yum install mysql mysql-server
3、加入启动项并启动mysql
chkconfig --levels 235 mysqld on
/etc/init.d/mysqld start
4、设置mysql密码及相关设置
mysql_secure_installation
因为第一次启动这命令，所以直接回车下一步，然后输入你的mysql密码，按照提示操作。
安装nginx
1、yum安装
yum --disablerepo=* --enablerepo=base --enablerepo=nginx install nginx
2、添加到启动项并启动nginx
chkconfig --levels 235 nginx on
/etc/init.d/nginx start
安装php
1、安装php及相关模块
yum install php-fpm php-cli php-mysql php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-mssql php-snmp php-soap php-tidy
２、编辑文件php.ini，在文件末尾添加cgi.fix_pathinfo = 1
vi /etc/php.ini
3、启动php-fpm
service php-fpm start
4、php-fpm加入启动项
chkconfig --levels 235 php-fpm on
修改nginx配置文件，添加fastcgi支持
１、修改nginx.conf文件
vi /etc/nginx/nginx.conf配置文件部分代码：[...]
server {
listen 80;
server_name _;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root /usr/share/nginx/html;
index index.php index.html index.htm;
}
error_page 404 /404.html;
location = /404.html {
root /usr/share/nginx/html;
}
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
root /usr/share/nginx/html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/share/nginx/html$fastcgi_script_name;
include fastcgi_params;
}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
location ~ /\.ht {
deny all;
}
}
[...]
33行的/usr/share/nginx/html修改为你的网站根目录。
２、重启nginx php-fpm/etc/init.d/nginx restart
/etc/init.d/php-fpm restart
3、建立info.php文件
vi /usr/share/nginx/html/info.php
添加如下代码：
<?php
phpinfo();
?>
在浏览器打开测试是否正常，如http://www.centos.bz/info.php。
