部署 Gitlab 及 gitlab-runner

目前gitlab官方给出的安装方式有很多种,普遍采用Omnibus包、Docker安装。官方说的😂我们强烈建议使用 Omnibus 包安装 GitLab ,因为它安装起来更快、更容易升级版本,而且包含了其他安装方式所没有的可靠性功能。

1.Omnibus包安装,也就是rpm包、deb包安装😂

CentOS7

# 安装依赖
sudo yum install -y curl policycoreutils-python openssh-server

# 添加官方的软件包源
# curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ee/script.rpm.sh | sudo bash

# 国内用户添加清华大学镜像站的源,下载速度会快些。

# 生成对应版本补丁文件
git diff v${gitlab_version} v${gitlab_version}-zh > ../${gitlab_version}-zh.diff

gitlab-ctl stop

# 打补丁的时候会提示一些补丁文件不存在,一定要跳过这些文件,不然后面reconfig的时候会报错的。
patch -d /opt/gitlab/embedded/service/gitlab-rails -p1 < ${gitlab_version}-zh.diff

# 重启gitlab
gitlab-ctl reconfigure
gitlab-ctl restart

reconfigure 失败

3.进行一些配置,gitlab的配置文件在/etc/gitlab/gitlab.rb

gitlab_rails['smtp_address'] = "smtp.office365.com"
gitlab_rails['smtp_port'] = 587
gitlab_rails['smtp_user_name'] = "[email protected]"

gitlab_rails['smtp_enable_starttls_auto'] = true
gitlab_rails['smtp_tls'] = true

安装 gitlab-runner

CentOS/RHEL

新建 /etc/yum.repos.d/gitlab-runner.repo,内容为

1
2
3
4
5
6

[gitlab-runner]
name=gitlab-runner
baseurl=https://mirrors.tuna.tsinghua.edu.cn/gitlab-runner/yum/el7
repo_gpgcheck=0
gpgcheck=0
enabled=1
gpgkey=https://packages.gitlab.com/gpg.key

再执行

sudo yum makecache
sudo yum install gitlab-runner -y
# 安装指定版本 其中 12.3.5 即为指定的版本号
yum install gitlab-runner-12.3.5-1.x86_64 -y

Debian/Ubuntu

首先信任 GitLab 的 GPG 公钥:

1
curl https://packages.gitlab.com/gpg.key 2> /dev/null | sudo apt-key add - &>/dev/null

再选择你的 Debian/Ubuntu 版本,文本框中内容写进 /etc/apt/sources.list.d/gitlab-runner.list

Debian

根据自己的发行版代号修改一下 stretch

1
deb http://mirrors.tuna.tsinghua.edu.cn/gitlab-runner/debian stretch main

Ubuntu

根据自己的发行版代号修改一下 bionic

1
deb https://mirrors.tuna.tsinghua.edu.cn/gitlab-runner/ubuntu bionic main

配置好 deb 源之后再执行

1
2
sudo apt uodate
apt install gitlab-runner -y

注册 gitlab-runner

使用 root 用户从 web 端登录到 gitlab 管理中心。在 概览 –> Runner 。在右上角会有以下,稍后会用到。

  • 在 Runner 设置时指定以下 URL
  • 在安装过程中使用以下注册令牌:

image-20200310202057916

安装好 gitlab-runner 之后如果直接向 gitlab 注册则会失败,提示 ERROR: Registering runner... failed runner=qRGh2M86 status=500 Internal Server Error

修改 gitlab 默认网络设置

使用 root 用户从 web 端登录到 gitlab 管理中心 http://${ip}/admin 。管理中心 –> 设置 –> 网络 –> 外发请求 –> 允许来自钩子和服务的对本地网络的请求。以下选项全部允许,才能通过外部请求的方式注册 gitlab-runner。

  • Allow requests to the local network from web hooks and services
  • Allow requests to the local network from system hooks

为了安全起见,也可以在 Whitelist to allow requests to the local network from hooks and services 下方的那个框框里添加上白名单,允许授权的 IP 。修改好之后不要忘记点击底部那个绿色按钮 保存修改

500 错误

如果点击 保存修改 之后就跳转到 Gitlab 500 错误的页面,这种情况比较僵硬😂。尝试在管理中心修改其他设置保存时,也会出现 500 的情况。在安装 gitlab 的机器上查看一下日志。运行 gitlab-ctl tail 查看实时的日志。此时等到日志输出减慢的时候我们多按几下回车,然后就立即去点击保存修改 按钮,这样就能捕捉到此刻的错误日志。

搜索了一下,发现网上说是由于迁移导入项目后,没有导入原来的加密信息/etc/gitlab/gitlab-secrets.json, 但是原来的加密信息文件我已经找不到了,后面发现可以直接重置就行了

参考 自搭gitlab报500错误

命令行输入gitlab-rails console,然后输入

ApplicationSetting.current.reset_runners_registration_token!即可,这样在保存修改的时候就不会再报 500 的问题了。应该是我重新安装 Gitlab 之后的加密信息不对所致🤔。

以上已经安装好并修改默认的网络设置允许 runner 所在的 IP 向 gitlab 发起外部请求。运行 gitlab-runner register 根据相应的提示输入 URLtoken 即可。最后根据机器的类型选择好 runner 的类型,这个也是跑 CI 任务时的环境,到时候可以在项目的设置中选择启动相应的 runner 。
