Nginx是一个高性能的HTTP和反向代理服务器，也是一个 IMAP/POP3/SMTP 服务器，因它的稳定性、丰富的功能集、示例配置文件和低系统资源的消耗而闻名。2011年6月1日，nginx 1.0.4发布。Nginx是一款轻量级的Web 服务器/反向代理服务器及电子邮件(IMAP/POP3)代理服务器，并在一个BSD-like 协议下发行。由俄罗斯的程序设计师Igor Sysoev所开发，供俄国大型的入口网站及搜索引擎Rambler（俄文：Рамблер）使用。其特点是占有内存少，并发能力强，事实上nginx的并发能力确实在同类型的网页服务器中表现较好，中国大陆使用nginx网站用户有：百度、新浪、网易、腾讯等。

Nginx

step1. Install Nginx

yum install -y pcre-devel zlib-devel gcc openssl-devel
useradd -M -s /sbin/nologin nginx
tar zxvf nginx-XXX -C /usr/local/
./configure -prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module --with-http_ssl_module --with-http_sub_module --with-md5=/usr/lib --with-sha1=/usr/lib --with-http_gzip_static_module
ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin
nginx -v #check nginx version

step2. Use nginx running script to change nginx service status.

##################################  Script nginx:

#############################SCRIPT END

cp nginx /etc/init.d
chmod +x /etc/init.d/nginx

step3. Edit nginx configure file
vim /usr/local/nginx/conf/nginx.conf

cd cmake
./configure && make && make install
tar zxvf mysql-XXX.tar.gz -C /usr/local
mv /usr/local/mysql-XXX /usr/local/mysql

cp mysql/support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
chkconfig --add mysqld
chkconfig mysqld on
/usr/local/mysql/scripts/mysql_install_db --user=mysql --defaults-file=/etc/my.cnf --basedir=/usr/local/mysql/ --> DB file store to /usr/local/mysql/data
useradd -M -s /sbin/nologin/ mysql
ln -s /usr/local/mysql/bin/*  /usr/local/bin
service mysqld restart
mysql_secure_installation  #optimization and set the password for mysql service
echo "//usr/local/mysql/lib" >> /etc/ld.so.conf
ldconfig

PHP

step1. Install PHP plugin

Install libmcrypt,mhash,mcrypt
tar jxvf php-XXX.tar.bz2
mv php-XXX.tar.bz2 php
cd php
./configure --prefix=/usr/local/php --with-gd --with-mcrypt --with-zlib --with-mysql=/usr/local/mysql --with-config-file-path=/usr/local/php/etc --enable-mbstring --enable-fpm && make && make install

step2. Initialization PHP

cp php/php.ini.development /usr/local/php/etc/php.ini
cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf

vim php-fpm.conf

pid=run/php-fpm.pid #close php-fpm service by find the pid number
user=nginx

        ;;
  *)
          echo "Usage: $SCRIPTNAME {start|stop|restart|reload}" >&2

exit 0
##################################SCRIPT END

chown +x /etc/init.d/php-fpm
chkconfig --add php-fpm
chkconfig --list php-fpm
chkconfig php-fpm on

step4. Add php plugin to nginx service
vim /usr/local/nginx/conf/nginx.conf

Enable extra "location ~\.php$" section ,use php proxy
    location ~\.php$ {
         proxy_pass http://NginxServerIP:80
     }

Edit original “localtion \” section to “location ~.php$” , do not use proxy

service {
     location ~\.php$ {
     root    html
     include        fastcgi.conf
     }
     Index    index.php
 }

        service nginx restart
        service php-fpm restart
        service nginx restart
