2>.安装nginx和php

3>.修改nginx的配置文件，添加一个匹配php文件的localtion

[root@node104.yinzhengjie.org.cn ~]# vim /etc/nginx/nginx.conf
[root@node104.yinzhengjie.org.cn ~]# 
[root@node104.yinzhengjie.org.cn ~]# egrep -v "^ *#|^$" /etc/nginx/nginx.conf
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
include /usr/share/nginx/modules/*.conf;
events {
    worker_connections 1024;
}
http {
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';
    access_log  /var/log/nginx/access.log  main;
    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 2048;
    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;
    include /etc/nginx/conf.d/*.conf;
    server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        server_name  _;
        root         /usr/share/nginx/html;
        include /etc/nginx/default.d/*.conf;
        location / {
        }
        location ~ \.php$ {
            root           html;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
        }
        error_page 404 /404.html;
            location = /40x.html {
        }
        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }
}
[root@node104.yinzhengjie.org.cn ~]# 
[root@node104.yinzhengjie.org.cn ~]# nginx -t　　　　　　　　　　　　　　#检查nginx的配置文件是否正确
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok

    option abortonclose
    maxconn 100000
    mode http
    timeout connect 300000ms
    timeout client  300000ms
    timeout server  300000ms
    errorloc 503 http://node107.yinzhengjie.org.cn/monitor/503.html

listen status_page
    bind 172.30.1.102:8888
    stats enable
    stats uri /haproxy-status
    stats auth    admin:yinzhengjie
    stats realm "Welcome to the haproxy load balancer status page of YinZhengjie"
    stats hide-version
    stats admin if TRUE
    stats refresh 5s

frontend WEB_PORT_80
    bind 172.30.1.102:80
    mode http
    #定义ACL匹配所有以".php"结尾的文件的php程序
    acl php_server path_end -i .php
    #将php的请求交给nginx服务器去处理.
    use_backend nginx_php if php_server
    #定义ACL匹配所有访问路径
    acl static_path path_beg -i /static /images /javascript
    #将图片的请求交给httpd服务器去处理.
    use_backend apache_httpd if static_path
    default_backend backup_web

backend nginx_php
    server web04 172.30.1.104:80  check inter 3000 fall 3 rise 5

backend apache_httpd
    server web03 172.30.1.103:80  check inter 3000 fall 3 rise 5

backend backup_web
    server web03 172.30.1.108:80  check inter 3000 fall 3 rise 5
