• I’m a new WPMU admin for a project that was handed off to me. We just moved from RHEL 7 / PHP 7 to RHEl 8 / PHP 8. We synced all of the files over and exported and imported the mysql db. There are some bugs but the bigger issue is the explosion of files being written taking up gigs and gigs of space. Primarily seems to be conflits between WP and SELinux. Below is an sample and volume:

    ~150k lines – the SElinux rw errors like ” node=xx.xx.com type=PATH msg=audit(1692121044.987:3540322): item=0 name=”/var/www/html/wp-includes/blocks/home-link.php” inode=35617045 dev=fd:06 mode=0100770 ouid=48 ogid=48 rdev=00:00 obj=unconfined_u:object_r:httpd_sys_content_t:s0 nametype=NORMAL cap_fp=0 cap_fi=0 cap_fe=0 cap_fver=0 cap_frootid=0OUID=”apache” OGID=”apache” ”

    ~150k lines – the SElinux rw errors like “node=xx.xx.com type=SYSCALL msg=audit(1692121044.987:3540322): arch=c000003e syscall=21 success=no exit=-13 a0=7f908a120478 a1=2 a2=0 a3=b2 items=1 ppid=3739573 pid=4136147 auid=4294967295 uid=48 gid=48 euid=48 suid=48 fsuid=48 egid=48 sgid=48 fsgid=48 tty=(none) ses=4294967295 comm=”php-fpm” exe=”/usr/sbin/php-fpm” subj=system_u:system_r:httpd_t:s0 key=(null)ARCH=x86_64 SYSCALL=access AUID=”unset” UID=”apache” GID=”apache” EUID=”apache” SUID=”apache” FSUID=”apache” EGID=”apache” SGID=”apache” FSGID=”apache” ”

    75k lines – messages like “node=xx.xx.com type=CWD msg=audit(1692121044.987:3540320): cwd=”/var/www/html” ”

    As a new admin that’s struggling with how to troubleshoot this, any guidance would be much appreciated!

  • Ask on an SELinux forum. I don’t know if those messages indicate a major error or are just warnings that could be ignored by changing the debug level.
