    四层代理

    再添加准备一台Nginx服务器做web应用层：（Nginx130）192.168.44.130

    添加一台nginx负载均衡服务器(Nginx140)：192.168.44.140

    Nginx+Tomcat负载均衡、动静分离

    名称ip地址
    Nginx 服务器192.168.44.120

    web192.168.44.130
    Nginx负载均衡192.168.44.140:8080

    Nginx130安装nginx

[root@localhost ~]# yum install -y epel-release
[root@localhost ~]# yum install -y nginx
[root@localhost ~]# cd /etc/nginx/
[root@localhost nginx]# vim nginx.conf

打开nginx120的主配置文件复制内容到130的配置文件如下
在#36 include /etc/nginx/conf.d/*.conf;下插入
