Detailed explanation of one-click installation of gitlab in centos

GitLab is an open source, web-interface Git code hosting tool that can help us better manage code in team collaboration development. If you are a developer, you are likely to encounter the following situations:

• A colleague modified your code without notifying you;
• Multiple people co-wrote the same code. A code base;
• There is no backup code, resulting in code loss.

In order to solve these problems, we can use GitLab to manage code. Let's introduce the one-click installation method of CentOS GitLab.

gitlab_rails['smtp_port'] = 465
gitlab_rails['smtp_user_name'] = "your_email@your_domain.com"
gitlab_rails['smtp_password'] = "your_password"
gitlab_rails['smtp_authentication'] = "login"
gitlab_rails['smtp_enable_starttls_auto'] = true
gitlab_rails['smtp_tls'] = true
gitlab_rails['smtp_openssl_verify_mode'] = 'none'

5. Start GitLab

Reload the configuration file:

sudo gitlab-ctl reconfigure

Start GitLab:

sudo gitlab-ctl start

At this point, we have completed the one-click installation of CentOS GitLab, which can be accessed using a browser Our GitLab service is available. Enter the server address and port in the browser address bar, for example:

http://192.168.1.100

GitLab default user name is "root" and password is "5iveL!fe".
