Gitlab installation
Update linux machine with yum update.
yum -y update
Once update is completed install postfix for notifications.
yum install postfix
service postfix start
chkconfig postfix on
Add the GitLab package repository and install the package
curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ee/script.rpm.sh | bash
Install gitlab package. Here specify the External URL you want gitlab to be accessed.
EXTERNAL_URL="http://192.168.100.25" yum -y install gitlab-ee
If you need to change EXTERNAL_URL or IP address of the host where gitlab is installed following are the steps.
1. Modify external_url parameter in file /etc/gitlab/gitlab.rb
2. gitlab-ctl reconfigure
Start gitlab with command below
gitlab-ctl start
Configure gitlab on 8888 port so that apache can be started on port 80.
Open /etc/gitlab/gitlab.rb and modify
nginx['listen_port'] = nil to nginx['listen_port'] = 8888
external_url 'http://192.168.100.25' to external_url 'http://192.168.100.25:8888'
Once modification completes execute reconfigure command
gitlab-ctl reconfigure
Restart gitlab to get the new setting in effect.
gitlab-ctl restart
Login to gitlab external url with following address
http://192.168.100.25:8888
Once you open page for the first time you need to set the root user password. Type root user password and click on Submit.
Now register new user. Click on Create project to add new gitlab project.
Set Project name. Click on Create Project.
Clone git repository locally.
git clone http://192.168.100.25:8888/dmaharjan/dilli_com_np.git
Add index page on local repository.
cd dilli_com_np
echo "This is index page" >> index.html
Add file, commit and push to git remote repository.
git add .
git commit -m "Adding index.html"
git push
Install apache. In our case apache server is web hosting for the client.
yum -y install httpd
Change directory to /var/www/html and clone git repo.
git clone http://dmaharjan@192.168.100.25:8888/dmaharjan/dilli_com_np.git
The page is accessible with the URL below:
http://192.168.100.25/dilli_com_np/index.html
Change directory to remote repository in our case /var/opt/gitlab/git-data/repositories/dmaharjan/dilli_com_np.git . Here dmaharjan is repos user and dilli_com_np is repository directory.
cd /var/opt/gitlab/git-data/repositories/dmaharjan/dilli_com_np.git
Create directory custom_hooks
Create hook file named post-receive with the content below
#!/bin/bash
cd /var/www/html/dilli_com_np
sudo /usr/bin/git stash
sudo /usr/bin/git pull
Change ownership of hook file and make it executable.
chown -R git:git post-receive
chmod 755 post-receive
Change sudo configuration and add following
git ALL=NOPASSWD: /usr/bin/git stash, /usr/bin/git pull
Change ownership of /var/www/html/dilli_com_np
chown -R apache:apache /var/www/html/dilli_com_np
Login as user git and verify sudo is working for user git. Make sure Password is not required for sudo and git pull
Now change the content of the local repo, add the file, commit it and push it. The hook should be executed and change should be reflected immediately on the web directory.
Change directory to local repository and add content to the file.
echo "Adding new line 1" >> index.html
git add .
git commit -m "Testing hook"
git push
View change on the web directory.
Troubleshooting:
Error: sudo: sorry, you must have a tty to run sudo while performing git push.
Search for Add Following lines "Defaults requiretty" and add Defaults:git !requiretty below the line.
You will get successfully push and hook file executed.
