Hi all:
logrotate is broken on my stock 4.1 install. After hunting and hunting I found there is a bug filed with Redhat on the issue. logrotate fails becasue my /tmp partition is mounted noexec. I understand it is that way for security reasons. The box in question is on a dedicated hosting site and that's the way it was handed off to me, built.
Some said setting TMPDIR=/var/tmp;export TMPDIR would fix it. My /var/tmp is not on a noexec partition so I'm good there. Setting TMPDIR however does not fix it. I've tried adding the variable in /etc/cron.daily/logrotate, I tried it after a prerotate inside the actual syslog logrotate file, netiher worked. I finally had to remount /tmp and remove the noexec. I have the stock 4.1 logrotate, I understand some later versions *may* address the TMPDIR but I hate to start straying off the stock/stable path since the main reason I am running Centos4.1 is to have a stable server platform that is maintained via yum update alone.
Has anyone fixed this on 4.1? Or have a workaround besides setting /tmp to exec or changing logrotate versions?
Thanks, Soctt
This is untested but in /etc/cron.daily/logrotate change /usr/sbin/logrotate /etc/logrotate.conf to TMPDIR=/var/tmp /usr/sbin/logrotate /etc/logrotate.conf
Should be all that is needed.
This line of code uses the TMPDIR value is in the runScript function logrotate.c: snprintf(buf, sizeof(buf), "%s/logrotate.XXXXXX", getenv("TMPDIR") ?: "/tmp");
