# Install Gitlab on RHEL 8

For installing Gitlab, we need minimum requirements of 2.5GB space and 4cores CPU.
If you have that, let's jump into the installation part.

```
sudo yum install -y curl policycoreutils-python openssh-server perl
```
# Enable OpenSSH server daemon if not enabled: sudo systemctl status sshd
```
sudo systemctl enable sshd
sudo systemctl start sshd
```

# Check if opening the firewall is needed with: sudo systemctl status firewalld
```
sudo firewall-cmd --permanent --add-service=http
sudo firewall-cmd --permanent --add-service=https
sudo systemctl reload firewalld
```
Install Postfix to send notification emails
```
sudo yum install postfix
sudo systemctl enable postfix
sudo systemctl start postfix
```
Create Gitlab repo in your local server
```
sudo vi /etc/yum.repos.d/gitlab.repo
```

Copy paste the below contents
```

[gitlab_gitlab-ee]
name=gitlab_gitlab-ee
baseurl=https://packages.gitlab.com/gitlab/gitlab-ee/el/8/$basearch
repo_gpgcheck=1
gpgcheck=1
enabled=1
gpgkey=https://packages.gitlab.com/gitlab/gitlab-ee/gpgkey
       https://packages.gitlab.com/gitlab/gitlab-ee/gpgkey/gitlab-gitlab-ee-D645A26AB9FBD22.pub.gpg
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
metadata_expire=300

[gitlab_gitlab-ee-source]
name=gitlab_gitlab-ee-source
baseurl=https://packages.gitlab.com/gitlab/gitlab-ee/el/8/SRPMS
repo_gpgcheck=0
gpgcheck=1
enabled=0
gpgkey=https://packages.gitlab.com/gitlab/gitlab-ee/gpgkey
       https://packages.gitlab.com/gitlab/gitlab-ee/gpgkey/gitlab-gitlab-ee-D645A26AB9FBD22.pub.gpg
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
metadata_expire=300
```

Then run,
```
sudo yum install gitlab_gitlab-ee
```

Once it is done, Gitlab will be installed in your server
To access it using 443 port securely, configure external URL

```
sudo vi /etc/gitlab/gitlab.rb
```

```
external_url "https://yourgitlab.com"
```

Then fire, 
```
sudo gitlab-ctl reconfigure

```
Check in https://yourgitlab.com
