1.启动nginx

[root@localhost ~]# docker run -it --name=myNginx -v /home/data:/etc/nginx -p 80:80 nginx

或者是查看之前启动的镜像进行直接启动

[root@localhost ~]# docker ps -a
    CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                      PORTS               NAMES

2.启动tomcat

3.nginx配置

这一步很重要：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：

开发80 8081端口并重启防火墙：这个步骤不弄的话访问不到。我表示弄了一周，才找到这个问题。

firewall-cmd --add-port=8081/tcp --permanent
    firewall-cmd --add-port=80/tcp --permanent
    
    systemctl restart firewalld.service

查看开放的端口：

[root@localhost ~]# firewall-cmd --list-all
    public (active)
      target: default
      icmp-block-inversion: no
      interfaces: enp0s3
      sources: 
      services: dhcpv6-client ssh
      ports: 8081/tcp 80/tcp
      protocols: 
      masquerade: no
      forward-ports: 
      source-ports: 
      icmp-blocks: 
      rich rules:

server {
        listen       80;
        server_name  localhost;
        location / {
                     proxy_pass http://192.168.101.13:8081/;   
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   /usr/share/nginx/html;
        }
    
    }

本机修改hosts可以搞个域名映射本机

重启nginx：

1.使用tomcat的地址访问：
