Gitlab

环境：

OS: CentOS7

安装 gitlab

常规安装 gitlab

进入官方下载地址：https://about.gitlab.com/install/ ，如下图，选择合适的版本。

以 CentOS7 为例：

安装和配置必要依赖

在系统防火墙中启用 HTTP 和 SSH

sudo yum install -y curl policycoreutils-python openssh-server
sudo systemctl enable sshd
sudo systemctl start sshd
sudo firewall-cmd --permanent --add-service=http
sudo systemctl reload firewalld

安装 Postfix ，使得 Gitlab 可以发送通知邮件

sudo yum install postfix
sudo systemctl enable postfix
sudo systemctl start postfix

添加 Gitlab yum 仓库并安装包

添加 Gitlab yum 仓库

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

通过 yum 安装 gitlab-ce

sudo EXTERNAL_URL="http://gitlab.example.com" yum install -y gitlab-ce

安装完成后，即可通过默认的 root 账户进行登录。更多细节可以参考：documentation for detailed instructions on installing and configuration

Docker 安装 gitlab

拉取镜像

docker pull docker.io/gitlab/gitlab-ce

启动

docker run --detach \
     --hostname 127.0.0.1 \
     --publish 8443:443 --publish 80:80 --publish 2222:22 \
     --name gitlab \
     --restart always \
     --volume /home/gitlab/config:/etc/gitlab \
     --volume /home/gitlab/logs:/var/log/gitlab \
     --volume /home/gitlab/data:/var/opt/gitlab \
     docker.io/gitlab/gitlab-ce:latest

安装 gitlab-ci-multi-runner

参考：https://docs.gitlab.com/runner/install/

常规安装 gitlab-ci-multi-runner

下载

sudo wget -O /usr/local/bin/gitlab-runner https://gitlab-runner-downloads.s3.amazonaws.com/latest/binaries/gitlab-runner-linux-amd64

配置执行权限

sudo chmod +x /usr/local/bin/gitlab-runner

如果想使用 Docker，安装 Docker（可选的）

curl -sSL https://get.docker.com/ | sh

创建 CI 用户

sudo useradd --comment 'GitLab Runner' --create-home gitlab-runner --shell /bin/bash

安装并启动服务

sudo gitlab-runner install --user=gitlab-runner --working-directory=/home/gitlab-runner
sudo gitlab-runner start

注册 Runner

（1）执行命令：

sudo gitlab-runner register

（2）输入 Gitlab URL 和 令牌

URL 和令牌信息在 Gitlab 的 Runner 管理页面获取：

Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com )
https://gitlab.com

Please enter the gitlab-ci token for this runner
xxx

（3）输入 Runner 的描述

 Please enter the gitlab-ci description for this runner
 [hostame] my-runner

（4）输入 Runner 相关的标签

 Please enter the gitlab-ci tags for this runner (comma separated):
 my-tag,another-tag

（5）输入 Runner 执行器

 Please enter the executor: ssh, docker+machine, docker-ssh+machine, kubernetes, docker, parallels, virtualbox, docker-ssh, shell:
 docker

如果想选择 Docker 作为执行器，你需要指定默认镜像（ .gitlab-ci.yml 中没有此配置）

 Please enter the Docker image (eg. ruby:2.1):
 alpine:latest

Docker 安装 gitlab-ci-multi-runner

拉取镜像

docker pull docker.io/gitlab/gitlab-runner

启动

docker run -d --name gitlab-runner --restart always \
   -v /srv/gitlab-runner/config:/etc/gitlab-runner \
   -v /var/run/docker.sock:/var/run/docker.sock \
   gitlab/gitlab-runner:latest

自签名证书

首先，创建认证目录

sudo mkdir -p /etc/gitlab/ssl
sudo chmod 700 /etc/gitlab/ssl

创建证书

创建 Private Key

sudo openssl genrsa -des3 -out /etc/gitlab/ssl/gitlab.domain.com.key 2048

会提示输入密码，请记住

生成 Certificate Request

sudo openssl req -new -key /etc/gitlab/ssl/gitlab.domain.com.key -out /etc/gitlab/ssl/gitlab.domain.com.csr

根据提示，输入信息

Country Name (2 letter code) [XX]:CN
State or Province Name (full name) []:JS
Locality Name (eg, city) [Default City]:NJ
Organization Name (eg, company) [Default Company Ltd]:xxxxx
Organizational Unit Name (eg, section) []:
Common Name (eg, your name or your server's hostname) []:gitlab.xxxx.io
Email Address []:

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:

移除 Private Key 中的密码短语

sudo cp -v /etc/gitlab/ssl/gitlab.domain.com.{key,original}
sudo openssl rsa -in /etc/gitlab/ssl/gitlab.domain.com.original -out /etc/gitlab/ssl/gitlab.domain.com.key
sudo rm -v /etc/gitlab/ssl/gitlab.domain.com.original

创建证书

sudo openssl x509 -req -days 1460 -in /etc/gitlab/ssl/gitlab.domain.com.csr -signkey /etc/gitlab/ssl/gitlab.domain.com.key -out /etc/gitlab/ssl/gitlab.domain.com.crt

移除证书请求文件

sudo rm -v /etc/gitlab/ssl/gitlab.domain.com.csr

设置文件权限

sudo chmod 600 /etc/gitlab/ssl/gitlab.domain.com.*

gitlab 配置

sudo vim /etc/gitlab/gitlab.rb
external_url 'https://gitlab.domain.com'

gitlab 网站 https：

nginx['redirect_http_to_https'] = true

gitlab ci 网站 https：

ci_nginx['redirect_http_to_https'] = true

复制证书到 gitlab 目录：

sudo cp /etc/gitlab/ssl/gitlab.domain.com.crt /etc/gitlab/trusted-certs/

gitlab 重新配置+更新：

sudo gitlab-ctl reconfigure
sudo gitlab-ctl restart
