Reposync - A better tool than mrepo. Use this to sync down all channels a RHEL system is subscribed to and turn them into locally exposed yum repositories.
#!/bin/bash
# This tool can be used to sync down Red Hat based packages from RHN using only Red Hat shipped tools
# Brian "Red Beard" Harrington <[email protected]>
# Copyright 2013
#
# To satisfy the pre-reqs for this script install the following two rpms:
# yum-utils
# createrepo_c (in RHEL 8 createrepo and createrepo_c have been combined)
# See https://github.com/rpm-software-management/createrepo_c#differences-in-behavior-between-createrepo_c-and-createrepo

By DB

SELECT table_schema "Data Base Name", sum( data_length + index_length ) / (1024 * 1024) as Size FROM information_schema.TABLES GROUP BY table_schema;

Opening and closing an SSH tunnel in a shell script the smart way

Opening and closing an SSH tunnel in a shell script the smart way

I recently had the following problem:

  • From an unattended shell script (called by Jenkins), run a command-line tool that accesses the MySQL database on another host.
  • That tool doesn't know that the database is on another host, plus the MySQL port on that host is firewalled and not accessible from other machines.

We didn't want to open the MySQL port to the network, but it's possible to SSH from the Jenkins machine to the MySQL machine. So, basically you would do something like

ssh -L 3306:localhost:3306 remotehost
