FreeBSD Apache 2.4 rewrite/proxy module errors

  • 772

Just set up a FreeBSD jail to run httpd in it and all works good except these two, rewrite/proxy modules.

These are error logs excerpts:

mod_rewrite error:

[rewrite:crit] [pid 43447] (13)Permission denied: AH00666: mod_rewrite: could not init rewrite_mapr_lock_acquire in child

mod_proxy error:

[proxy:crit] [pid 43447] (13)Permission denied: AH02479: could not init proxy_mutex in child

Not sure permissions of what are being denied as html in document root is being served just fine when these modules are disabled.

I tried googling but found nothing but rubbish.

apache-2.2

  1. Sounds like your jail lacks permissions for SysV IPC. Try to set sysvipc_allow=1 in your jail settings or pass it with jail command.

    The issue were permissions.

    I set /etc/pw.conf umask to 007 from default 022 and that resulted in certain executables being unable to be reached from jails.

    Once i changed containing directory permissions to original ones it all started working properly and modules are not logging errors any more.

    Typical example of PEBKAC.
