Reids报错解决：Job for redis-server.service failed

早上在启动redis的时候报错如下：

1

3
-> # service redis-server start
Job for redis-server.service failed because the control process exited with error code.
See "systemctl status redis-server.service" and "journalctl -xe" for details.

里面有关键的一句： redis-server[29517]: 29517:C 10 May 14:48:08.460 # Fatal error, can't open config file '/etc/redis/redi 这句话让我想起了我修改了redis.conf，现在redis.conf是root用户，而redis用户是没有权限读取的。

解决方法：

1
2
chmod 644 /etc/redis/redis.conf
service redis-server start
