To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root,and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled. 5617:M 18 Sep 12:57:10.438 * DB loaded from disk: 0.000 seconds 5617:M 18 Sep 12:57:10.438 * The server is Now ready to accept connections on port 6379

3 启动客户端

redis-cli

127.0.0.1:6379> ping
PONG

4 检查 Redis 服务器系统进程

ps -aux|grep redis

ubuntu    5617  0.0  0.7  38856  7884 pts/0    Sl+  12:57   0:01 redis-server *:6379
ubuntu    5707  0.0  0.0  12944   976 pts/1    S+   13:22   0:00 grep redis

5 通过端口检查 Redis 服务器状态

netstat -nlt|grep 6379

tcp        0      0 0.0.0.0:6379            0.0.0.0:*               LISTEN     
tcp6       0      0 :::6379                 :::*                    LISTEN

6 通过启动命令检查 Redis 服务器状态

sudo /etc/init.d/redis-server status

redis-server is running
