Redis fails to start after reboot (“Can't open the log file: Permission denied”)












0















I've ran into a problem with my Redis 4.09 installation on Ubuntu 18.04.
Each time I reboot the machine the /var/log/redis/redis-server.log ends up being owned by www-data:www-data:



# namei -l /var/log/redis/redis-server.log
f: /var/log/redis/redis-server.log
drwxr-xr-x root root /
drwxr-xr-x root root var
drwxrwxr-x root syslog log
drwxr-x--- redis redis redis
-rw-r----- www-data www-data redis-server.log


# stat /var/log/redis/redis-server.log

File: /var/log/redis/redis-server.log
Size: 0 Blocks: 0 IO Block: 4096 regular empty file
Device: fc04h/64516d Inode: 131151 Links: 1
Access: (0640/-rw-r-----) Uid: ( 33/www-data) Gid: ( 33/www-data)
Access: 2019-01-01 06:25:03.050853905 +0100
Modify: 2019-01-01 06:25:03.050853905 +0100
Change: 2019-01-01 06:25:03.050853905 +0100
Birth: -


This results in the redis.service refusing to start. The same thing happens when I invoke redis-server directly:



# sudo -u redis redis-server /etc/redis/redis.conf 

*** FATAL CONFIG FILE ERROR ***
Reading the configuration file, at line 171
>>> 'logfile /var/log/redis/redis-server.log'
Can't open the log file: Permission denied

          Eh. Solved it. Slightly embarrassing.

          I botched an usermod and the redis-user ended up in the www-data group as the primary group:



          # groups redis
          redis : www-data


          The fix was usermod -g redis redis.
