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 psdocker exec -it 01c626690608 /bin/bash
cd webapps/ROOT/
echo "<h1>Apache Tomcat 8088</h1>" >index.jspcat index.jspexitdocker 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
另外一个也是一样的
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
