4. 容器管理练习

4.1 启动一个nginx和tomcat容器

[root@vms41 ~]# docker run -dit --name=web -p 80:80 --restart=always nginx
a49a7d8df0318e984d9d21bf0a638cadef452bb54707a31b333d8fdd549f1f3a
[root@vms41 ~]# docker ps -a
CONTAINER ID   IMAGE     COMMAND                  CREATED          STATUS         PORTS                               NAMES
a49a7d8df031   nginx     "/docker-entrypoint.…"   10 seconds ago   Up 8 seconds   0.0.0.0:80->80/tcp, :::80->80/tcp   web
[root@vms41 ~]# docker run -dit --name=web -p 80:8080 --restart=always hub.c.163.com/library/tomcat:latest

4.2 docker常用管理命令

docker exec 容器名 命令 ---在容器中临时执行命令
docker stop 容器名 ---停止容器
docker start 容器名 --启动容器
docker restart 容器名 --重启容器
docker logs 容器名 --查看容器日志
docker top 容器名 --查看容器进程运行情况
docker inspect 容器名 --查看容器的详细属性

[root@vms41 ~]# docker run -dit --name=db --restart=always -e MYSQL_ROOT_PASSWORD=haha001 -p 3307:3306 hub.c.163.com/library/mysql:latest
