=head1 DESCRIPTION |
|
|
This script modifies /etc/yum.conf and /etc/my.cnf to ensure certain parameters |
This script modifies /etc/my.cnf, /etc/yum.conf, /etc/yum.repos.d/loncapa.repo, |
are set properly. The LON-CAPA yum repositories are added to /etc/yum.conf. |
/etc/apt/sources, or /etc/sysconfig/rhn/sources to ensure certain |
|
parameters are set properly. |
|
|
|
The LON-CAPA yum repositories are added to /etc/yum.conf, |
|
/etc/yum.repos.d/loncapa.repo, /etc/sysconfig/rhn/sources |
|
and the LON-CAPA apt repositories are added to |
|
/etc/apt/sources.list. |
|
|
The /etc/my.cnf file is modified to set the wait_timeout to 1 year. Backup |
The /etc/my.cnf file is modified to set the wait_timeout to 1 year. Backup |
copies of each file are made in /etc. |
copies of each file are made in /etc, /etc/apt, and /etc/sysconfig/rhn, as |
|
appropriate. |
