redis - 更改目录后无法启动redis服务器

Question

我用

安装了redis

sudo apt-get -y install redis-server 

默认数据目录是/var/lib/redis/，但是当我换到另一个目录/some path/redisDB 文件:sudo gedit/etc/redis/redis.conf 时，我无法再次启动redis 服务器。我得到一个错误

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.

你引用的路径不存在或者启动redis的用户没有写入权限。
