 安装顺序是 Nginx > php> mysql>redis

查看： 
[root@iZgahlk1l73998Z /]# rpm -qa |grep mysql
mysql-libs-5.1.73-8.el6_8.i686
卸载mysql 
[root@iZgahlk1l73998Z /]# rpm -e mysql-libs-5.1.73-8.el6_8.i686 --nodeps
[root@iZgahlk1l73998Z /]# rpm -qa |grep php

1、安装编译工具和库文件

[root@iZgahlk1l73998Z /]# yum -y install make zlib zlib-devel gcc-c++ libtool  openssl openssl-devel

 2、安装PCRE

PCRE 作用是让 Nginx 支持 Rewrite 功能

下载 PCRE 安装包，下载地址： http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

[root@iZgahlk1l73998Z src]# wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz
[root@iZgahlk1l73998Z src]# tar zxvf pcre-8.35.tar.gz

 3、进入pcre 编译安装 默认安装 没有指定位置：

[root@iZgahlk1l73998Z pcre-8.35]# ./configure
[root@iZgahlk1l73998Z pcre-8.35]#  make & make install

 4、查看PCRE 版本

[root@iZgahlk1l73998Z pcre-8.35]#  pcre-config --version
8.35

 安装Nginx：

1、下载 Nginx，下载地址：http://nginx.org/download/nginx-1.6.2.tar.gz

[root@iZgahlk1l73998Z src]# wget http://nginx.org/download/nginx-1.6.2.tar.gz
[root@iZgahlk1l73998Z src]# tar zxvf nginx-1.6.2.tar.gz

 2、安装

[root@iZgahlk1l73998Z nginx-1.6.2]# ./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.35
[root@iZgahlk1l73998Z nginx-1.6.2]# make
[root@iZgahlk1l73998Z nginx]# /usr/local/webserver/nginx/sbin/nginx -v

3、配置Nginx.conf

创建运行Nginx 用户和用户组

groupadd nginx
useradd nginx -g nginx -s /sbin/nologin -M

或者在编译安装的时候指定，先创建
--with-user=nginx 
--with-group=nginx
在编译Nginx.config的时候 记得使用
user nginx nginx;

#user  nobody;
user nginx nginx;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

 #   log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
  #                    '$status $body_bytes_sent "$http_referer" '
   #                   '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

   server_names_hash_bucket_size 128;
   client_header_buffer_size 32k;
   large_client_header_buffers 4 32k;
   client_max_body_size 8m;
sendfile on;
   tcp_nopush on;
   keepalive_timeout 60;
   tcp_nodelay on;
   fastcgi_connect_timeout 300;
   fastcgi_send_timeout 300;
   fastcgi_read_timeout 300;

   fastcgi_temp_file_write_size 128k;
   gzip on;
   gzip_min_length 1k;
   gzip_buffers 4 16k;
   gzip_http_version 1.0;
   gzip_comp_level 2;
   gzip_types text/plain application/x-javascript text/css application/xml;
   gzip_vary on;
   #charset koi8-r;


 server
  {
    listen 80;#监听端口
    server_name localhost;#域名
    index index.html index.htm index.php;
    root /usr/local/webserver/nginx/html;#站点目录
      location ~ .*.(php|php5)?$
    {
     # fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_pass 127.0.0.1:9000;
      fastcgi_index index.php;
      include fastcgi.conf;
      }
    location ~ .*.(gif|jpg|jpeg|png|bmp|swf|ico)$
     {
        expires 30d;
      # access_log off;
      }
     location ~ .*.(js|css)?$
     {
      expires 15d;
     # access_log off;
      }
      access_log off;
      }


   }

 4、测试下

[root@iZgahlk1l73998Z conf]# /usr/local/webserver/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/webserver/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/webserver/nginx/conf/nginx.conf test is successful

 5、启动

[root@iZgahlk1l73998Z conf]# /usr/local/webserver/nginx/sbin/nginx
[root@iZgahlk1l73998Z conf]# ps -ef |grep nginx
root     21160     1  0 14:47 ?        00:00:00 nginx: master process /usr/local/webserver/nginx/sbin/nginx
nginx    21161 21160  0 14:47 ?        00:00:00 nginx: worker process                
root     21163  1546  0 14:48 pts/0    00:00:00 grep nginx

/usr/local/webserver/nginx/sbin/nginx -s reload            # 重新载入配置文件
/usr/local/webserver/nginx/sbin/nginx -s reopen            # 重启 Nginx
/usr/local/webserver/nginx/sbin/nginx -s stop              # 停止 Nginx
