1. 安装docker

apt install apt-transport-https ca-certificates curl gnupg-agent software-properties-common

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | apt-key add -

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

参考文章：

1. 如何在 Ubuntu 20.04 上安装和使用 Docker-阿里云开发者社区 (aliyun.com)

2. 安装gitlab-ce

apt-get install postfix -y

cd /tmp
curl -LO https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.deb.sh

apt update
apt install gitlab-ce

# 或者从清华源上下载下来，使用 dpkg -i <deb> 手动安装

安装完成后，修改配置文件：

vim /etc/gitlab/gitlab.rb
# 修改external_url 为幺使用的服务器地址
external_url 'https://x.x.x.x:8100'

# 修改数据存放目录
git_data_dirs({
  "default" => {
    "path" => "/mnt/nfs-01/git-data"
   }
})

设置存储仓库数据的备用目录
注意的是：自GitLab 8.10开始,可以通过在/etc/gitlab/gitlab.rb文件中添加下面的几行配置， 来增加多个 git 数据存储目录。

git_data_dirs({
  "default" => { "path" => "/var/opt/gitlab/git-data" },  //默认存储目录
  "alternative" => { "path" => " /home/gitlab-data" }     //备用存储目录
})


# 修改postgressql的端口

# 停止gitlab服务 
sudo gitlab-ctl stop

# 启动gitlab服务 
sudo gitlab-ctl reconfigure

# 重启所有gitlab组件 
sudo gitlab-ctl restart

# 启动所有gitlab组件 
sudo gitlab-ctl start

# 启用开机自启动
sudo systemctl enable gitlab-runsvdir.service

初始化数据

gitlab-rake gitlab:setup

3. gitlab配置邮箱

参考文章：Gitlab服务器邮箱配置，实现自动为用户发送邮件_gitlab邮箱发送邮件_SageCat郭帅强的博客-CSDN博客

# gitlab_rails['smtp_enable'] = true
# gitlab_rails['smtp_address'] = "smtp.server"
# gitlab_rails['smtp_port'] = 465
# gitlab_rails['smtp_user_name'] = "smtp user"
# gitlab_rails['smtp_password'] = "smtp password"
# gitlab_rails['smtp_domain'] = "example.com"
# gitlab_rails['smtp_authentication'] = "login"
# gitlab_rails['smtp_enable_starttls_auto'] = true
# gitlab_rails['smtp_tls'] = false
# gitlab_rails['smtp_pool'] = false

使用命令测试邮件：

Notify.test_email('xxx@xxx.com','email title','email content desc').deliver_now

4. pip更换源

pip config set global.index-url https://mirrors.aliyun.com/pypi/simple/

5. 500错误处理

查看日志/var/log/gitlab/gitlab-rails/production.log

6. 邮件配置遇到的错误

主要有这么几种错误：

# gitlab-rails console

通常来说，都是tls的问题，需要修改配置：

gitlab_rails['smtp_tls'] = false
gitlab_rails['smtp_enable_starttls_auto'] = false

这两个全改为flase即可发送成功。

7. 使用docker部署极狐版本

export GITLAB_HOME=/data1/gitlab

sudo docker run --detach \
  --hostname gitlab.example.com \
  --publish 8443:443 --publish 8100:80 --publish 8022:22 \
  --name gitlab \
  --restart always \
  --volume $GITLAB_HOME/config:/etc/gitlab \
  --volume $GITLAB_HOME/logs:/var/log/gitlab \
  --volume $GITLAB_HOME/data:/var/opt/gitlab \
  --shm-size 8192m \
  registry.gitlab.cn/omnibus/gitlab-jh:latest
