Install GitLab CE on CentOS 7

Install GitLab on CentOS really simple and you can find a lot of similar articles. But I wrote this article during installing and my comments may be helpful for you.


  • CentOS 7.x. I used for this article 7.6
  • Server with minimum 2Gb of RAM. I will use a local server for local usage
  • 5 minutes of your time

If you are lazy as me – just check out ready script on GitHub. But please check the end of this article about performance.

Let’s Install GitLab on CentOS

In each my project I used CentOS. I don’t know why – maybe I love it or don’t want to be in the mainstream of Ubuntu howtos. You may check my other articles for CentOS about install PostgreSQL and the golanding project.

First – it should be first, think about firewall and install it:

yum install -y firewalld firewall-config
systemctl start firewalld

and add http and https services to your default zone:

firewall-cmd --permanent --add-service=http
firewall-cmd --permanent --add-service=https
systemctl reload firewalld

Fuh. Now I’m quite. Now we can start to install Gitlab. Start from dependencies:

yum install -y curl policycoreutils-python openssh-server
Also, we have to install postfix which will send emails from own server:
yum install -y postfix
systemctl start postfix
systemctl enable postfix
Add GitLab package YUM repo to own system:
curl | bash
And we almost ready start installing of Gitlab. But you should set env EXTERNAL_URL to your domain and run install after it.
yum install -y gitlab-ce

That’s all folks! After it, you should open your GitLab in the browser and set up the root password and so on.


I: A machine with 1xCPU and 2Gb of RAM will be enough for GitLab.


GitLab CentOS

That’s right – 2Gb of RAM not enough even for 1 user. You will be get “502 error” very often. You need a machine with 8Gb of RAM instead.

Conclusion and improvements

In my case – I don’t need an SSL certificate for my GitLab because it works only in a local network.

For serving GitLab on Cloud – please set up SSL for your server. For example good howto – How to Install and Configure GitLab CE on CentOS 7. Come on, 2k19 – it has to be secure.
