Add Logfile to Memcache/Memcached Daemon on Linux
If you need to add a log file for
memcache to help debug an issue, you can either use the following syntax:
memcached -d -m 3072 -l localhost -p 11211 -u nobody -v 2>>/tmp/memcached.log
or if you’re on RHEL/CentOS, you can edit the file
/etc/sysconfig/memcached like so:
PORT="11211" USER="memcached" MAXCONN="3048" CACHESIZE="256" OPTIONS="-vv >> /var/log/memcached 2>&1"
Save the file, restart memcache and you’ll have a log file. This was taken from this StackOverflow question.
