为现有redis的docker容器设置密码

1.进入redis的docker容器

docker exec -it myredis /bin/bash

2. 修改 /redis.conf 文件

[root@87d0586c0fb5 /]# ls
anaconda-post.log  bin  data  dev  Downloads  dump.rdb  etc  home  lib  lib64  log  media  mnt  opt  proc  redis5  redis.conf  root  run  sbin  srv  sys  tmp  usr  var

vim /redis.conf

3.找到有 requirepass 字段的这一行,将注释去掉并,修改密码

# Require clients to issue AUTH <PASSWORD> before processing any other
# commands.  This might be useful in environments in which you do not trust
# others with access to the host running redis-server.
#
# This should stay commented out for backward compatibility and because most
# people do not need auth (e.g. they run their own servers).
#
# Warning: since Redis is pretty fast an outside user can try up to
# 150k passwords per second against a good box. This means that you should
# use a very strong password otherwise it will be very easy to break.
#
requirepass mypassword

4.退出容器,并且重启redis的docker容器

docker restart myredis
