redis练习

使用容器在后台运行redis，然后切到容器内去交互式执行sh，通过容器的redis-cli命令可以练习redis的使用。

~# docker run --rm -d redis:alpine
325c8e99841b595d4b0d481e2f8ef5144c59ef31e9ab03b210304523ab5d2602
~#
~# docker ps
CONTAINER ID   IMAGE          COMMAND                  CREATED         STATUS         PORTS      NAMES
325c8e99841b   redis:alpine   "docker-entrypoint.s…"   3 minutes ago   Up 3 minutes   6379/tcp   clever_lewin
~#
~# docker exec -it 325 sh
/data # redis-cli
127.0.0.1:6379> help
redis-cli 7.0.0
To get help about Redis commands type:
      "help @<group>" to get a list of commands in <group>
      "help <command>" for help on <command>
      "help <tab>" to get a list of possible help topics
      "quit" to exit

To set redis-cli preferences:
      ":set hints" enable online hints
      ":set nohints" disable online hints
Set your preferences in ~/.redisclirc
