固定IP

vi /etc/sysconfig/network-scripts/ifcfg-ens33

BOOTPROTO=static

IPADDR=192.168.95.128
NETMASK=255.255.255.0
GATEWAY=192.168.95.2

#DNS文件配置
vi /etc/resolv.conf 
nameserver 8.8.8.8
nameserver 8.8.4.4

然后重启网络：service network restart

目录结构

nginx.conf

文件要提前创建要不然启动的时候会认为是目录

worker_processes  1;

events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    client_header_buffer_size 2k;
#    反向代理
    upstream tomcatServer1 {
#   负载均衡
         server tomcat1:8080;
         server tomcat2:8080;
    }
    server {
        listen       80;
        #   域名映射
        server_name  service1.funtl.com;
        location / {
            proxy_pass http://tomcatServer1;
            index  index.html index.htm;
        }
    }
    #   静态资源
    server {
        listen       80;
        server_name  service2.funtl.com;
        location / {
            root   /usr/share/nginx/html/html81;
            index  index.html index.htm;
        }
