Detailed explanation of how to build GitLab on Linux server

Linux GitLab server construction

GitLab is an open source Git management platform. It provides code warehouse management, version control, code review and other functions, so it is one of the first choices for most teams for collaborative development. Here, I will introduce how to set up GitLab on a Linux server.

1. Install the necessary software

First, we need to install the necessary software. In the Ubuntu system, we can use the following command to install:

sudo apt-get install curl openssh-server ca-certificates postfix

Among them, Postfix is ​​the software used to send emails, and we need to configure it.

2. Configuring Postfix

In this step, we need to configure Postfix to send emails. GitLab requires sending emails as a method of verification and notification, so this is a must. We can edit the /etc/postfix/main.cf file to make the following modifications:

myhostname = your.server.com # 修改为你自己的服务器域名
mydestination = your.server.com, localhost.localdomain, localhost
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0/104] [::1/128]
relayhost = 
# 在这里配置your.server.com的MX记录

# 下面两条是开启SSL的配置
smtp_tls_CAfile = /etc/postfix/cacert.pem
smtp_tls_security_level = may

# 开启SMTP认证
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noanonymous
smtp_sasl_tls_security_options = noanonymous
smtp_tls_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem
smtp_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key
smtp_use_tls = yes

The above modifications are based on the Postfix of the Ubuntu system, and the configurations of different versions may be different. Next, we need to create the /etc/postfix/sasl_passwd file and edit it:

[smtp.gmail.com]:587 username@gmail.com:password

where [smtp.gmail.com]:587 is the address and port of the Gmail server, if you are using another For the email service provider, you need to query the service provider for the SMTP address and port. Username@gmail.com and password are your Gmail account and password and need to be replaced with your own.

After completing the above modifications, we need to start Postfix with the following command:

sudo service postfix restart

3. Install GitLab

Now it is time to install GitLab. We need to visit the official website of GitLab and download the latest GitLab installation file, as shown below:

curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.deb.sh | sudo bash

After the download is completed, we need to install GitLab:

sudo apt-get install gitlab-ce

After the installation is completed, we enter / etc/gitlab directory, and edit the gitlab.rb file:

sudo vim /etc/gitlab/gitlab.rb

In the file, we need to make some basic configurations, as shown below:

external_url 'http://your.server.com' # 这里也需要修改为你自己的服务器域名
#
# 下面是SMTP的配置
#
gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.gmail.com"
gitlab_rails['smtp_port'] = 587
gitlab_rails['smtp_user_name'] = "username@gmail.com" # 你的Gmail账户
gitlab_rails['smtp_password'] = "password" # Gmail的SMTP密码
gitlab_rails['smtp_domain'] = "smtp.gmail.com"
gitlab_rails['smtp_authentication'] = "login"
gitlab_rails['smtp_enable_starttls_auto'] = true
gitlab_rails['smtp_tls'] = false

After the modification is completed, we need to execute The following command:

sudo gitlab-ctl reconfigure

After the execution is completed, we can access GitLab:

http://your.server.com/

Now, we have successfully set up GitLab on the server and can start using it for collaborative development .
