Git With Automatic Upload and Synchronization to a Production Server

Prerequisites
#

Git installed on your local machine and the production server.
SSH access to the production server.
A Git repository on your local machine.

Step
#

Initialize a Git Repository

First, make sure you have a Git repository set up on your local machine. If you don’t have one, you can initialize it using:

cd /path/to/your/project
git init

Set Up the Remote Repository

You’ll need a bare repository on your production server to which you will push your code.

# On your production server
mkdir -p /var/repo/your_project.git
cd /var/repo/your_project.git
git init --bare

Add the Remote Repository

On your local machine, add the production server repository as a remote:

git remote add production user@production_server:/var/repo/your_project.git

Replace user with your username on the production server and production_server with the server’s address.

Push Code to the Production Server

Push your local repository to the production server:

git push production master

Post-Receive Hook for Deployment

Create a post-receive hook on the production server to automatically deploy the code when pushed.

# On your production server
cd /var/repo/your_project.git/hooks
nano post-receive

Add the following script to post-receive:

#!/bin/bash
GIT_WORK_TREE=/var/www/your_project git checkout -f

Make the hook executable:

chmod +x post-receive

Automate Sync with Git Hooks (Optional)

To automate the push to the production server every time you commit or push to your local repository, you can use Git hooks on your local machine.

Post-Commit Hook

This hook will push changes to the production server every time you commit.

# On your local machine
cd /path/to/your/project/.git/hooks
nano post-commit

Add the following script:

#!/bin/bash
git push production master

Make the hook executable:

chmod +x post-commit

Post-Push Hook

This hook will push changes to the production server every time you push to your remote repository.

# On your local machine
cd /path/to/your/project/.git/hooks
nano post-push

Add the following script:

#!/bin/bash
git push production master

Make the hook executable:

chmod +x post-push

Test the Setup

Make a commit and push it to see if everything works as expected.

git add .
git commit -m "Test commit"
git push

Check your production server to ensure the changes are deployed.

Notes
#

Make sure your production server is secure and only accessible by authorized users.
Consider setting up a more advanced deployment tool (like Capistrano, Ansible, or Docker) for larger projects or more complex deployment needs.
Always have backups and a rollback strategy in place in case something goes wrong during deployment.

This setup ensures that your code is automatically uploaded and synchronized with your production server whenever you commit or push changes to your local repository.

Configure Git on Server
#

Add user to handle the repositories:

# sudo adduser git

# sudo su — git

Initiate a new empty repository using following command:

# git init — bare ~/hostnextra.git

Enable post-update hook by copying the sample file as follows:

# cd hostnextra.git/hooks/
# cp post-update.sample post-update

That’s it for server side.

Configure Git on Client
#

Submit inflammation about yourself so that commit messages will be generated with correct information attached:

# git config — global user.name “git”
# git config — global user.email “git@hub.hostnextra.com”

Create a directory where you can keep all your projects

# mkdir ~/dev
# cd ~/dev

Now, create a clone the hostnextra.git repository that we have created earlier in the server

# git clone git@hub.hostnextra.com:~/hostnextra.git hostnextra.git
Cloning into ‘hostnextra.git’…

It will ask to enter git user password:

git@hub.hostnextra.com’s password:

warning: You appear to have cloned an empty repository.

Go to respository

# cd hostnextra.git

You can see the repository is empty, so lets create some files

# echo “my test file” > file1.txt

Add these file to our git repository

# git add .

Commit the changes

# git commit -am “My First Commit”
[master (root-commit) b337197] My First Commit
1 file changed, 1 insertion(+)
create mode 100644 file1.txt

Push these changes to the remote git repository at hub.hostnextra.com

# git push origin master

you will be asked for password, enter git user password

git@hub.hostnextra.com’s password:

To hub.hostnextra.com:~/hostnextra.git
* [new branch] master -> master

Verify the changes, access the git server and run following command to check the logs

# git log

Output will be similar like:

commit b3371975bd44fb4aca344e365fa635180967f7fe (HEAD -> master)
Author: git <git@hub.hostnextra.com>
