Complete!


# 启动docker并设置开机自启
[root@cloud ~]# systemctl enable docker --now
# 查看状态
[root@cloud ~]# systemctl status docker

拉取镜像并启动，配置http访问

# 网络拉取gitlab镜像
[root@cloud ~]# docker pull gitlab/gitlab-ee:latest
# 这里其实可以不用执行docker pull，执行docker run的时候如果没有对应的image则会自动执行pull来获取image


# 直接配置并启动
[root@cloud ~]# docker run --detach \
> --hostname gitlab \
> --publish 8443:443 \
> --publish 8080:80 \
> --publish 2222:22 \
> --name gitlab \
> --restart always \
> --volume /opt/gitlab/config:/etc/gitlab \
> --volume /opt/gitlab/logs:/var/log/gitlab \
> --volume /opt/gitlab/data:/var/opt/gitlab \
> --shm-size 256m \
> gitlab/gitlab-ee:latest


# 完成后查看运行状态
[root@cloud ~]# docker ps

# 查看gitlab初始化过程
[root@cloud ~]# docker logs -f gitlab


# 进入容器gitlab后台
[root@cloud ~]# docker exec -it gitlab /bin/bash

访问页面

# 账号：root
# 查看初始页面登录密码
[root@cloud ~]# grep 'Password:' /opt/gitlab/config/initial_root_password
Password: J7ndtscfQII0/LaG3tzfkmKgwui58pvRLlkOQj6ojm0=

• 访问页面： http://172.20.10.4:8080

• 基本配置：设置本地中文及更改密码

http配置到此结束，下面为https访问相关配置！

配置证书

# 创建ssl证书目录
[root@cloud ~]# mkdir /opt/gitlab/config/ssl/
# 设置权限
[root@cloud ~]# chmod 755 /opt/gitlab/config/ssl/
# 切换到ssl目录下
[root@cloud ~]# cd /opt/gitlab/config/ssl/
# 创建证书
[root@cloud ssl]# openssl req -x509 -newkey rsa:1024 -keyout gitlab.key -out gitlab.crt -nodes -days 36500

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.

修改配置文件并启用https支持

# 切换目录，备份gitlab.rb
[root@cloud ssl]# cd ..
[root@cloud config]# cp gitlab.rb gitlab.rb.bak
# 修改配置文件，添加下列内容
[root@cloud config]# vim gitlab.rb
33 external_url "https://172.20.10.4:8443"
1400 nginx['redirect_http_to_https'] = true
1414 nginx['ssl_certificate'] = "/etc/gitlab/ssl/gitlab.crt"
1415 nginx['ssl_certificate_key'] = "/etc/gitlab/ssl/gitlab.key"
# 配置页面git及https连接
[root@cloud config]# vim /opt/gitlab/data/gitlab-rails/etc/gitlab.yml
    host: 172.20.10.4
    port: 8443
    https: true




# 保存退出，进入docker容器内，重新加载配置文件
[root@cloud ~]# docker exec -it gitlab /bin/bash
root@gitlab:~# gitlab-ctl reconfigure

访问页面

• 刷新访问页面http://172.20.10.4:8080
  • 返回 https://gitlab.example.cn/ 表示https配置成功
• 访问新页面即可：https://172.20.10.4:8443，使用默认密码或前面更过的登录即可

git客户端问题

• 问题描述：使用git采用https进行的clone，结果出现错误 SSL certificate problem: self signed certificate

• 原因：SSL认证失败

• 解决办法：关闭SSL的认证

• git客户端执行如下命令：

  git config --global http.sslVerify false

相关配置文件

/opt/gitlab/data/gitlab-rails/etc/gitlab.yml
/opt/gitlab/config/gitlab.rb


docker exec -it gitlab /bin/bash
/var/opt/gitlab/gitlab-rails/etc/gitlab.yml
/etc/gitlab/gitlab.rb

重置root密码

• 登录到 Gitlab 服务器，执行如下命令：

  gitlab-rails console production

• 如果此时有报错：

  Traceback (most recent call last):

  Usage: "rails console [options]"

• 则可能是 Gitlab 版本不一样，然后参数方式不一样，需要用如下方式：

  gitlab-rails console -e production

• 接着查询一下用户：

  user = User.where(username:"root").first
  => #<User id:1 @root>

• 然后修改密码：（至少8位）

  user.password = "Admin@123"
  => "Admin@123"

• 然后保存：

  user.save!
  Enqueued ActionMailer::DeliveryJob (Job ID: 1f015e02-34bc-4b26-8e37-3101937b7ce1) to Sidekiq(mailers) with arguments: "DeviseMailer", "password_change", "deliver_now", #<GlobalID:0x00007fa6b83b1378 @uri=#<URI::GID gid://gitlab/User/1>>
  => true

• 保存之后，可以使用如上密码Admin@123进行登陆，登陆之后，记得更改密码！
