$ mkdir -p /data/docker/nginx1/conf
$ mkdir /data/docker/nginx1/html
$ mkdir /data/docker/nginx1/logs
$ mkdir -p /data/docker/{tomcat1,tomcat2,tomcat3}/webapps/ROOT
$ mkdir /data/docker/{tomcat1,tomcat2,tomcat3}/logs

配置容器

4.启动tomcat容器并创建新首页

$ docker run -d -p 8081:8080 -v /data/docker/tomcat1/webapps:/usr/local/tomcat/webapps -v /data/docker/tomcat1/logs:/usr/local/tomcat/logs --name tomcat1 tomcat
$ docker run -d -p 8082:8080 -v /data/docker/tomcat2/webapps:/usr/local/tomcat/webapps -v /data/docker/tomcat2/logs:/usr/local/tomcat/logs --name tomcat2 tomcat
$ docker run -d -p 8083:8080 -v /data/docker/tomcat3/webapps:/usr/local/tomcat/webapps -v /data/docker/tomcat3/logs:/usr/local/tomcat/logs --name tomcat3 tomcat

配置新首页

1

$ for i in {1..3};do echo "this is tomcat$i" > /data/docker/tomcat$i/webapps/ROOT/index.jsp;done

5.配置nginx.conf并按配置文件启动
