系统运维

简介

在生产环境中，很多企业会经常使用nginx + tomcat 架构，nginx作为负载均衡器，反向代理，tomcat作为节点服务器。在docker容器中也可以使用这种架构。
对这种架构感兴趣的可以参考博客：https://blog.51cto.com/13760351/2161850

操作环境

备注：实验中已关闭防火墙，打好企业使用的war包

部署过程：
一、安装nginx镜像

可参考博客 https://blog.51cto.com/13760351/2469063

二、部署war包项目

部署及排坑过程可参考博客 https://blog.51cto.com/13760351/2469305

三、修改nginx配置文件

vim /etc/nginx/nginx.conf

user  nginx;
worker_processes  1;
error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       /etc/nginx/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 $upstream_addr\';

    access_log  /var/log/nginx/access.log  main;
    sendfile        on;
    #tcp_nopush     on;
    keepalive_timeout  65;
    #gzip  on;
    upstream tomcat {
        server 47.99.150.153:8088 weight=1;  #添加权重
        server 47.99.150.155:8088 weight=1;
    }

    server {
        listen 80;
        server_name localhost;

                location / {
            root  /usr/share/nginx/html;
            index  index.html index.htm;
            }

        location /admin {
            proxy_pass http://tomcat;  #添加
            proxy_redirect off;
            index index.html index.htm;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Real-Port $remote_port;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
    }

    include /etc/nginx/conf.d/*.conf;
}
