Docker中nginx+tomcat实现负载均衡

拉取tomcat镜像

docker pull tomcat

运行两个tomcat容器

docker run -d -p 8088:8080 --name tomcat8088 tomcat
    docker run -d -p 8089:8080 --name tomcat8089 tomcat

修改下index.jsp把两个tomcat区别开来

docker ps
    docker exec -it 01c626690608 /bin/bash
    cd webapps/ROOT/
    echo "<h1>Apache Tomcat 8088</h1>" >index.jsp
    cat index.jsp
    exit
    docker restart 01c626690608

echo "test" >index.jsp  替换index.jsp的内容

echo "test" >>index.jsp 在文件末尾追加内容

获取nginx镜像

docker pull nginx

创建目录

mkdir -p /data/nginx/{conf,conf.d,html,logs}

创建配置文件nginx.conf

vim /data/nginx/conf/nginx.conf

                    server 192.168.1.4:8089 weight=5;
        }
    
    }

创建nginx容器

docker run --name mynginx -d -p 80:80  -v /data/nginx/conf/nginx.conf:/etc/nginx/nginx.conf  -v /data/nginx/logs:/var/log/nginx -d docker.io/nginx
