This script modifies /etc/my.cnf and one of: /etc/yum.conf |
This script modifies local MySQL configuration file(s), which will be: |
(for CentOS/Scientific Linux/RHEL >=5 and <8), /etc/apt/sources.list |
/home/www/.my.cnf and, depending on distro/version also one of: |
(for Debian/Ubuntu), /etc/sysconfig/rhn/sources (for RHEL4), |
/etc/my.cnf, /etc/mysql/my.cnf, /etc/mysql/mysql.conf.d/mysqld.cnf, |
and /etc/yum.repos.d/loncapa.repo (Fedora >= 21; Oracle Linux; |
or /etc/mysql/mariadb.conf.d/50-server.cnf, and also the file used to |
CentOS/RHEL >= 8). |
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. |
