Description Jamie Nguyen 2012-12-20 10:55:28 UTC
Logrotation of nginx log files in /var/log/nginx/*.log is prevented from executing properly by SELinux policy. Once the log files have been rotated, the nginx web server needs to be told to re-open the log files with SIGUSR1.



/etc/logrotate.d/nginx contains:

  postrotate
      /bin/systemctl kill --signal=SIGUSR1 nginx.service
  endscript



/var/log/audit/audit.log contains:
==========
type=USER_AVC msg=audit(1355990461.465:299): pid=1 uid=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:init_t:s0 msg='avc:  denied  { stop } for auid=0 uid=0 gid=0 path="/usr/lib/systemd/system/nginx.service" cmdline="/bin/systemctl kill --signal=SIGUSR1 nginx.service" scontext=system_u:system_r:logrotate_t:s0-s0:c0.c1023 tcontext=system_u:object_r:systemd_unit_file_t:s0 tclass=service  exe="/usr/lib/systemd/systemd" sauid=0 hostname=? addr=? terminal=?'
