1.当设置密码后，上面的关闭命令无效：带密码输入：    redis-cli -a [password]     回车后输入：shutdown save

shutdown还有一个参数，代表关闭redis服务前是否生产持久化文件

shutdown save

[root@localhost redis]# ps aux | grep redis
root      3384  0.0  0.7 152412  7812 ?        Ssl  21:16   0:00 ./bin/redis-server 192.168.146.128:6379
root      3389  0.0  0.0 103248   832 pts/0    S+   21:16   0:00 grep redis
[root@localhost redis]# ./bin/redis-cli -a 123456
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.
127.0.0.1:6379> shutdown save
not connected> exit
[root@localhost redis]# ps aux | grep redis
root      3389  0.0  0.0 103248   832 pts/0    S+   21:16   0:00 grep redis
[root@localhost redis]#

　　

2.kill -9 pid 进程

[root@localhost redis]# ps aux | grep redis
root      3384  0.0  0.7 152412  7812 ?        Ssl  21:16   0:00 ./bin/redis-server 192.168.146.128:6379
root      3389  0.0  0.0 103248   832 pts/0    S+   21:16   0:00 grep redis
[root@localhost redis]# kill -9 3384
[root@localhost redis]# ps aux | grep redis
root      3401  0.0  0.0 103248   832 pts/0    S+   21:17   0:00 grep redis
[root@localhost redis]#
