架构说明：

使用nginx+tomcat实现动态/静态（资源请求）分离和负载均衡。

参考文档：

https://www.runoob.com/docker/docker-tutorial.html

配置docker镜像仓库：/etc/docker/daemon.json

{
        "registry-mirrors": ["https://registry.docker-cn.com", "http://hub-mirror.c.163.com", "https://pee6w651.mirror.aliyuncs.com"]
    }

下载nginx和tomcat的镜像：

docker pull nginx
    docker pull tomcat

创建nginx和tomcat本地目录，稍后将挂载到docker容器上：

mkdir -p ~/nginx/www ~/nginx/conf/ ~/nginx/logs
    mkdir -p ~/tomcat/webapps/ROOT ~/tomcat/conf ~/tomcat/logs

在tomcat/webapps/ROOT中创建index.html：

<!DOCTYPE html>
    <html>
    <head>
        <meta charset="UTF-8">
        <title>docker deployment</title>
    </head>
    <body>
        <h1>hello, world</h1>
        <img src="/static/image/lichmama.png">
    </body>
    </html>

启动tomcat：

docker run -d --name tomcat1 -v ~/tomcat/webapps:/usr/local/tomcat/webapps tomcat
    docker run -d --name tomcat2 -v ~/tomcat/webapps:/usr/local/tomcat/webapps tomcat

获取tomcat容器IP，获取到的IP将配置到nginx的配置文件中：

docker inspect tomcat1|grep "IPAddress"
    docker inspect tomcat2|grep "IPAddress"

在nginx/conf增加配置文件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 172.17.0.2:8080;
            server 172.17.0.4:8080;
        }
    
        server {
            listen 80;
            server_name localhost;
    
            location / {
                proxy_pass http://tomcat;
                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;
            }
    
            location /static/ {
                alias /usr/share/nginx/html/;
            }
        }
    
        include /etc/nginx/conf.d/*.conf;
    }

启动nginx：

docker run -d -p 80:80 --name nginx -v ~/nginx/www:/usr/share/nginx/html -v ~/nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v ~/nginx/logs:/var/log/nginx nginx

使用docker ps查看docker进程：

访问http://server\_ip/index.html：

![644402-20190816204151669-313297097.png][]

OK，部署成功。
