Description Martin Frodl 2015-05-13 16:26:04 UTC

PLEASE NOTE: this bug is not identical to bug 963146. Bug 963146 describes troubles related to graceful start of a stopped server, whereas this one points out similar yet different issue with graceful restart of a running server. While the former bug has been fixed (tested on httpd-2.2.15-45.el6.x86_64), this one persists.

+++ This bug was initially created as a clone of Bug #1221275 +++

Description of problem:

Similar to RHEL-6 bug 963146. When the HTTPD_LANG variable is changed in /etc/sysconfig/httpd and Apache restarted gracefully, the value is not updated.

Reproducer:
Create file /var/www/html/info.php containing the following code:
---
<?php
    print "LANG=" . getenv('LANG') . "\n";
?>
---
# service httpd start
# curl http://localhost/info.php
LANG=C
# echo 'HTTPD_LANG=ja_JP.utf-8' > /etc/sysconfig/httpd
# service httpd graceful
# curl http://localhost/info.php
LANG=C
# service httpd restart
# curl http://localhost/info.php
LANG=ja_JP.utf-8

Version-Release number of selected component (if applicable):

Comment 2 Jan Kaluža 2015-11-02 08:53:58 UTC

During the graceful restart, it is not possible to change the value of LANG variable. That would mean changing the value of environment variable of running process, which is not possible.

The previous old RHEL-6 bug 963146 is about graceful restart when httpd is *not* running. In that case, graceful restart started the httpd and the LANG variable has been ignored for that newly started httpd instance. But this should work as expected in RHEL7.
