提示不能删除一个正在运行的容器。
[root@vm000949 ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
695d5f6afc27 redis "docker-entrypoint.sh" 14 minutes ago Up 8 minutes 127.0.0.1:6379->6379/tcp ecstatic_lamarr果然这个容器正在运行，将该容器stop,并再次删除容器
[root@vm000949 ~]# docker stop 695d5f6afc27
695d5f6afc27（2）docker create
1.首先创建，其语法与run相似
[root@vm000949 ~]# docker create -p 127.0.0.1:6379:6379 -it --name="my-redis-server" -d redis
unknown shorthand flag: 'd' in -d
See 'docker create --help'.我就直接将run修改为create。但是可以想象的是create里面还是没有这个选项，且没有开始运行怎么会有-d
b.再次尝试创建。去掉-d
[root@vm000949 ~]# docker create -p 127.0.0.1:6379:6379 -it --name="my-redis-server" redis
Error response from daemon: Conflict. The name "/my-redis-server" is already in use by container d66037100bddcd230e0c9955bdfb9b0dbae8ce4028a81534e1693ab95737c90a. You have to remove (or rename) that container to be able to reuse that name.好吧，上次run创建的还没有删除
