How to Check Archived Log Files

Redis also archives older log files. See a list of the archived logs with: 

 ls /var/log/redis 

Output

redis-server.log  redis-server.log.1.gz

You can gunzip an older file:

sudo gunzip /var/log/redis/redis-server.log.1.gz

Now to see its last 10 lines:

sudo tail /var/log/redis/redis-server.log.1

Using find to Search for Logs

If logs are not found in any of these locations then you can find it by more general search using find in the /var/logs directory:

find /var/log/* -name *redis*

Or you can search your entire system. It will turn up a few permission warnings, which is normal.It will also turn up every file with redis in the name, which includes installation files:

find / -path /sys -prune -o -path /proc -prune -o -name *redis*

Setting the Log Location in redis.conf

Log files of Redis is specified in Redis's configuration file, redis.conf, often located at /etc/redis/redis.conf.

Open that file for editing:

sudo nano /etc/redis/redis.conf 

Locate the logfile line:

/etc/redis/redis.conf

logfile /var/log/redis/redis-server.log
