CentOS 8 v @OracleLinux 8 v IBMredhat 8 network install #devops #sysadmin

CentOS 7/8 network install

it just works ! and autodetects yum repo installation source



OracleLinux 7/8 network install

you need to manually setup the yum repo installation source


IBMredhat 7/8 network install


A) you need a ibm red hat subscription (or ‘free’ developer subscription)

B) even if you have a subscription you need to create your own yum repo server

so you have to install everything from your subscription DVD instead

in #centos 6.x #percona 5.x #phpmyadmin 4.x reads config file from a new directory #dba #devops #sysadmin

in #centos 6.x #percona 5.x #phpmyadmin 4.x reads its config file from a completely different directory – it is no longer in the phpmyadmin code directory

ACTUAL centos 6 percona 5 phpmyadmin 4 config files are as follows

  • phpMyAdmin httpd – /etc/httpd/conf.d/phpMyAdmin.conf
  • phpMyAdmin conf – /etc/phpMyAdmin/config.inc.php
  • phpMyAdmin code – /usr/share/phpMyAdmin/
