Description James Hartsock 2017-04-17 20:06:09 UTC

Description of problem:

When installing httpd via yum and apache group already exists on the system with GID other than 48 (for example when it is defined in IDM), installation is not able to create apache user because '-g 48' is used on RHEL 7.

This worked in RHEL 6 because '-g apache' was utilized.  Now that BZ 1299889 has split the group & user creation into individual commands, believe useradd should be modified to use '-g apache' in RHEL 7 (as it is already in RHEL 6).


Version-Release number of selected component (if applicable):
httpd-2.4.6-45.el7

How reproducible:
Very

Steps to Reproduce:
1. Make apache group resolvable, but do NOT use GID=48.  Generally this would be resolved from IDM, but here just using local user to replicate issue.
   # groupadd -g 4800 apache

2. Install httpd
   # yum install httpd


Actual results
NOTE: useradd -g 48 (like RHEL 7 httpd preinstall)
# getent passwd apache
# getent group apache
apache:x:4800:

# /usr/sbin/useradd -c "Apache" -u 48 -g 48 -s /sbin/nologin -r -d /usr/share/httpd apache
useradd: group '48' does not exist




Expected results:
NOTE: useradd -g apache (like RHEL 6 httpd preinstall)

# getent passwd apache
# getent group apache
apache:x:4800:

# getent passwd apache >/dev/null || useradd -r -u 48 -g apache -s /sbin/nologin -d /var/www -c "Apache" apache

# echo $?
0
