配置GitLab笔记

1. 安装必要的依赖服务

安装postfix邮件服务器
sudo yum install postfix -y
sudo service postfix start
sudo chkconfig postfix on
sudo lokkit -s http -s ssh        //如果没有lokkit，可以自己用 yum install lokkit 安装。事实上 lokkit 也只是设定 iptables 把 http 和 ssh 打开，如果原本就有开了也不用执行或手动自己设置 iptables 也可以。

2. 安装gitlab

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

国内安装的话可以使用清华的源
新建 /etc/yum.repos.d/gitlab-ce.repo，内容为
[gitlab-ce]
name=Gitlab CE Repository
baseurl=https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el$releasever/
gpgcheck=0
enabled=1

再执行
sudo yum makecache
sudo yum install gitlab-ce -y

3. Configure and start GitLab

sudo gitlab-ctl reconfigure

4. 启用https

生成自签名证书
sudo mkdir /etc/gitlab/ssl/
cd ssl
sudo openssl req -newkey rsa:2048 -x509 -nodes -days 3560 -out gitlab.crt -keyout gitlab.key
修改配置，开启https
vi /etc/gitlab/gitlab.rb
修改 external_url 
external_url "https://git.abc.com"   //有域名用域名，没有域名用ip
nginx['redirect_http_to_https'] = true
nginx['ssl_certificate'] = "/etc/gitlab/ssl/gitlab.crt"
nginx['ssl_certificate_key'] = "/etc/gitlab/ssl/gitlab.key"
sudo gitlab-ctl reconfigure重建配置
使用gitlab-ctl restart来重启所有服务, 即可使用HTTPS访问GitLab了

5. 如果要把ip改成域名，需要改一下几个地方

vi /etc/gitlab/gitlab.rb
external_url "https://git.abc.com"   //有域名用域名
server {
  listen *:80;
  server_name git.abc.com;
  server_tokens off; ## Don't show the nginx version number, a security best practice
  return 301 https://www.abc.com:443$request_uri;    //改成域名
  access_log  /var/log/gitlab/nginx/gitlab_access.log gitlab_access;
  error_log   /var/log/gitlab/nginx/gitlab_error.log;
}

vi /var/opt/gitlab/gitlab-rails/etc/gitlab.yml
host:git.abc.com
sudo gitlab-ctl restart

6. 把已有仓库导入到gitlab

sudo cp -r /data/repo/test.git /var/opt/gitlab/git-data/repositories/test-group/test.git
sudo chown -R git:git /var/opt/gitlab/git-data/repositories/test-group/
sudo gitlab-rake gitlab:import:repos

7. 测试通知邮件是否能正常发送

echo "Test mail from postfix" | mail -s "Test Postfix" [email protected]
-bash: mail: command not found
yum -y install mailx

8. 克隆项目

首先，生成ssh key
ssh-keygen -t rsa -C "[email protected]" -b 4096
执行克隆
git clone [email protected]:test-group/test.git
Cloning into 'test'...
warning: You appear to have cloned an empty repository.

git clone https://git.abc.com/test-group/test.git
Cloning into 'test'...
mac: fatal: unable to access 'https://git.abc.com/test-group/test.git/': SSL certificate problem: Invalid certificate chain
解决办法：
git -c http.sslVerify=false clone  https://git.abc.com/test-group/test.git
windows:
fatal: unable to access 'https://username:[email protected]/test-grou          p/editors.git/': SSL certificate problem: self signed certificate
解决办法：
SourceTree->设置->选项->git->禁用ssl验证
Git Bash->执行git config http.sslVerify false，禁用SSL验证
