查看redis是否启动使用的是 ps aux | grep redis-server 命令
ps aux | grep redis-server可以在根目录下使用，也可以在其他目录下使用
[red@RedFace sbin]$ cd /
[red@RedFace /]$ ps aux | grep redis-server
red 6218 0.0 0.0 4420 760 pts/1 S+ 04:50 0:00 grep redis-server
[red@RedFace /]$
[red@RedFace /]$ cd -
/usr/local/nginx/sbin
[red@RedFace sbin]$ ps aux | grep redis-server
red 6223 0.0 0.0 4420 760 pts/1 S+ 04:51 0:00 grep redis-server
[red@RedFace sbin]$ 运行redis
ps aux | grep redis-server[root@localhost bin]# ls
dump.rdb redis-benchmark redis-check-aof redis-check-rdb redis-cli redis.conf redis-sentinel redis-server
[root@localhost bin]# ps aux | grep redis-server
