Simple automated GIT Deployment using Hooks

Simple automated GIT Deployment using GIT Hooks

Here are the simple steps needed to create a deployment from your local GIT repository to a server based on this in-depth tutorial.

How it works

You are developing in a working-copy on your local machine, lets say on the master branch. Most of the time, people would push code to a remote server like github.com or gitlab.com and pull or export it to a production server. Or you use a service like deepl.io to act upon a Web-Hook that's triggered that service.

Getting latest tag on git repository
# The command finds the most recent tag that is reachable from a commit.
# If the tag points to the commit, then only the tag is shown.
# Otherwise, it suffixes the tag name with the number of additional commits on top of the tagged object
# and the abbreviated object name of the most recent commit.
git describe
# With --abbrev set to 0, the command can be used to find the closest tagname without any suffix:
git describe --abbrev=0

Just a simple Mysql Replication Health Check script I wrote. You can put this in a cron.
#!/bin/bash
### VARIABLES ### \
EMAIL=""
SERVER=$(hostname)
MYSQL_CHECK=$(mysql -e "SHOW VARIABLES LIKE '%version%';" || echo 1)
LAST_ERRNO=$(/usr/bin/mysql -e "SHOW SLAVE STATUS\G" | grep "Last_Errno" | awk '{ print $2 }')
SECONDS_BEHIND_MASTER=$(/usr/bin/mysql -e "SHOW SLAVE STATUS\G"| grep "Seconds_Behind_Master" | awk '{ print $2 }')
IO_IS_RUNNING=$(/usr/bin/mysql -e "SHOW SLAVE STATUS\G" | grep "Slave_IO_Running" | awk '{ print $2 }')
SQL_IS_RUNNING=$(/usr/bin/mysql -e "SHOW SLAVE STATUS\G" | grep "Slave_SQL_Running" | awk '{ print $2 }')
