redis error：Waiting for Redis to shutdown ...（无法关闭redis）

Posted 2021-05-17 TaKe___Easy

• 问题：
  无法关闭redis服务，提示一直等待关闭

[root@localhost init.d]# /etc/init.d/redis_6379 stop
Stopping ...
Could not connect to Redis at 127.0.0.1:6379: Connection refused

Waiting for Redis to shutdown ...

• 原因：
  redis启用安全认证，requirepass该配置后，对应也要修改启动和关闭的脚本，在脚本关闭处指定IP和密码参数：-h 192.168.131.10 -a password
• 修改:
  修改/etc/init.d/redis_6379文件的第43行。指定主机IP和密码参数

[root@localhost ~]# cd /etc/init.d/
[root@localhost init.d]# ls
functions  netconsole  network  README  redis_6379
[root@localhost init.d]# vim redis_6379 
 43             $CLIEXEC -h 192.168.131.10 -p $REDISPORT -a hadoop shutdown

[root@localhost init.d]# /etc/init.d/redis_6379 stop

• 或者直接将密码设置为空
