안녕하세요.



꿈꾸는여행자입니다.


 
OpenShift 환경에서 자주 사용되는 Git Tool, Gitlab CE 환경 구성을 공유 하고자 합니다.

 

해당 내역은 기존 Gitlab 사전 구성  준비 이후, Gitlab 설치 관련된 사항입니다.


상세 내역은 아래와 같습니다.


감사합니다.

* Then install the Gitlab community edition with the following command.
sudo dnf install gitlab-ce -y
2.2.3. Configure GitLab on RHEL 9|CentOS 9
* Set up your DNS to the URL at which you want to access your GitLab instance.
sudo hostnamectl set-hostname gitlab.technixleo.com
* To change the GitLab URL access, edit the configuration file.
   * Change the external URL to your domain name.
   * You can set a password for the initial administrator user account (root).
sudo cp /etc/gitlab/gitlab.rb /etc/gitlab/gitlab.rb.orig
sudo vi /etc/gitlab/gitlab.rb
	external_url 'https://gitlab.technixleo.com'
external_url 'https://cicd.ocpcst.ldsproject.com'
external_url 'http://cicd.ocpcst.ldsproject.com'
gitlab_rails['initial_root_password'] = 'ldssmart1160!!'
* Reconfigure the instance to save changes.
sudo gitlab-ctl reconfigure
2.2.4. Secure GitLab with SSL
* SSL 적용 실패 
* We can secure GitLab with a Self-signed certificate or a Let’s Encrypt certificate.
2.2.4.1. Self-signed Certificate
* Create the following directory to generate a self-signed certificate and set appropriate permissions.
sudo mkdir -p /etc/gitlab/ssl
sudo chmod 755 /etc/gitlab/ssl
* Generate the self-signed certificate and store it in the directory with the following command.
sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 \
    -keyout /etc/gitlab/ssl/cicd.ocpcst.ldsproject.com.key \
    -out /etc/gitlab/ssl/cicd.ocpcst.ldsproject.com.crt
	[root@cicd ~]# sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048     -keyout /etc/gitlab/ssl/cicd.ocpcst.ldsproject.com.key     -out /etc/gitlab/ssl/cicd.ocpcst.ldsproject.com.crt
…
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [XX]:KR
State or Province Name (full name) []:Seoul
Locality Name (eg, city) [Default City]:GangNam
Organization Name (eg, company) [Default Company Ltd]:Exam
Organizational Unit Name (eg, section) []:Exam
Common Name (eg, your name or your server's hostname) []:cicd.ocpcst.ldsproject.com
Email Address []:ktm@linuxdata.co.kr
[root@cicd ~]#
* Edit the configuration file to provide the SSL certificate paths.
sudo vi /etc/gitlab/gitlab.rb
nginx['enable'] = true
nginx['client_max_body_size'] = '250m'
nginx['redirect_http_to_https'] = true
nginx['ssl_certificate'] = "/etc/gitlab/ssl/cicd.ocpcst.ldsproject.com.crt"
nginx['ssl_certificate_key'] = "/etc/gitlab/ssl/cicd.ocpcst.ldsproject.com.key"
nginx['ssl_protocols'] = "TLSv1.1 TLSv1.2 TLSv1.3"
* Reconfigure your instance to apply the changes.
sudo gitlab-ctl reconfigure
2.2.4.2. Let’s Encrypt certificate
* Edit the GitLab configuration file with the following settings.
sudo vi /etc/gitlab/gitlab.rb
	letsencrypt['enable'] = true
letsencrypt['contact_emails'] = ['ktm@linuxdata.co.kr'] # This should be an array of email addresses to add as contacts
letsencrypt['auto_renew'] = true
* Then reconfigure the instance to apply changes
sudo gitlab-ctl reconfigure
2.2.5. Start Service 
* Restart
