127.0.0.1:6379>如果是用apt-get或者yum install安装的redis，可以直接通过下面的命令停止/启动/重启redis/etc/init.d/redis-server stop
/etc/init.d/redis-server start
/etc/init.d/redis-server restart注意：使用/etc/init.d/redis-server start 方法启动redis,那么在那个目录下启动redis,那么redis的备份文件就在那个目录下。
如在/user/bin/redis/目录下输入命令/etc/init.d/redis-server start ，那么redis备份文件就在/user/bin/redis/dump.rdb
如果是通过源码安装的redis，则可以通过redis的客户端程序redis-cli的shutdown命令来重启redisredis-cli -h 127.0.0.1 -p 6379 shutdown
如果上述方式都没有成功停止redis，则可以使用终极武器 kill -9
