Start redis client

redis-cli 
127.0.0.1:6379>

If redis is installed using apt-get or yum install, you can directly stop/start/restart redis through the following commands

/etc/init.d/redis-server stop
/etc/init.d/redis-server start
/etc/init.d/redis-server restart

Note: Use /etc/ The init.d/redis-server start method starts redis, then start redis in that directory, then the redis backup file is in that directory.

If you enter the command /etc/init.d/redis-server start in the /user/bin/redis/ directory, then the redis backup file is in /user/bin/redis/dump.rdb

If redis is installed through source code, you can restart redis through the shutdown command of the redis client program redis-cli

redis-cli -h 127.0.0.1 -p 6379 shutdown

If none of the above methods successfully stop redis, you can use the ultimate weapon kill -9
