=head1 SYNOPSIS |
=head1 SYNOPSIS |
|
|
This script modifies /etc/yum.conf and /etc/my.cnf. |
This script modifies local MySQL configuration file(s), which will be: |
|
/home/www/.my.cnf and, depending on distro/version also one of: |
|
/etc/my.cnf, /etc/mysql/my.cnf, /etc/mysql/mysql.conf.d/mysqld.cnf, |
|
or /etc/mysql/mariadb.conf.d/50-server.cnf, and also the file used to |
|
store information about the LON-CAPA package repositories located at |
|
install.loncapa.org. which provide rpm or deb packages created for the |
|
Linux distro/version being used. The file to modify will be one of: |
|
/etc/yum.conf (for CentOS/Scientific Linux/RHEL >=5 and <8), |
|
/etc/apt/sources.list (for Debian < 10 and Ubuntu < 22), or |
|
/etc/apt/sources.list.d/loncapa.list (for Debian >= 10 and Ubuntu > 20), |
|
/etc/sysconfig/rhn/sources (for RHEL4), or /etc/yum.repos.d/loncapa.repo |
|
(for Fedora >= 21; Oracle Linux; AlmaLinux; RockyLinux; CentOS/RHEL >= 8). |
|
|
|
The script also modifies /home/www/.inputrc on Linux distros which have |
|
readline 8.1 or newer, i.e., CentOS/Scientific Linux/RHEL >= 9, |
|
Ubuntu >= 22, Debian >= 12, and Fedora >= 34. |

=head1 DESCRIPTION |
|
|
This script modifies /etc/yum.conf and /etc/my.cnf to ensure certain parameters |
This script will modify /etc/my.cnf, /etc/mysql/my.cnf, |
are set properly. The LON-CAPA yum repositories are added to /etc/yum.conf. |
/etc/mysql/mysql.conf.d/mysqld.cnf, or |
The /etc/my.cnf file is modified to set the wait_timeout to 1 year. Backup |
/etc/mysql/mariadb.conf.d/50-server.cnf, |
copies of each file are made in /etc. |
and /etc/yum.conf, /etc/yum.repos.d/loncapa.repo, |
|
/etc/apt/sources.list, /etc/apt/sources.list.d/loncapa.list or |
|
/etc/sysconfig/rhn/sources and /home/www/.inputrc to ensure |
|
certain parameters are set properly. |
|
|
|
The LON-CAPA yum repositories are added to /etc/yum.conf, |
|
/etc/yum.repos.d/loncapa.repo, or /etc/sysconfig/rhn/sources |
|
and the LON-CAPA apt repositories are added to |
|
/etc/apt/sources.list or /etc/apt/sources.list.d/loncapa.list. |
|
|
|
The /etc/my.cnf, /etc/mysql/my.cnf /etc/mysql/mysql.conf.d/mysqld.cnf |
|
or /etc/mysql/mariadb.conf.d/50-server.cnf file is modified to set the |
|
wait_timeout to 1 year. Backup copies of each file are made in |
|
/etc, /etc/apt, and /etc/sysconfig/rhn, as appropriate. |
