Hi,
I installed redis-server v5.0.7 on Ubuntu 20.04 with apt install redis-server. I am recieving always an error: systemd[1]: redis-server.service: Can’t open PID file /run/redis/redis-server.pid (yet?) after start: Operation not permitted
I changed the pidfile option in /etc/redis/redis.conf from /run/redis/redis-server.pid to /var/run/redis/redis-server.pid and restarted the server with sudo systemctl restart redis-server but it still gives same error.
And redis-server.service file under /etc/systemd/system look as following:
...
[Service]
Type=forking
ExecStart=/usr/bin/redis-server /etc/redis/redis.conf
PIDFile=/var/run/redis/redis-server.pid
TimeoutStopSec=0
Restart=always
User=redis
Group=redis
RuntimeDirectory=redis
RuntimeDirectoryMode=2755
....
It still gives error that it can not read file /run/redis/redis-server.pid. There is no other option with /run/.. elsewhere.
Where does it come from? How can I solve the problem?
