CentOS 7.x上GitLab搭建详细教程(2)

该配置根据官网提供的配置修改而来： https://gitlab.com/gitlab-org/gitlab-recipes/blob/master/web-server/nginx/gitlab-omnibus-nginx.conf。

重启nginx:

$sudo service nginx restart

4.登陆浏览器，这时可以看到安装成功了，如下图所示：

首次登陆会要求重置管理员密码，管理员的默认用户名为root。

https的支持

1.使用Let's encrypt申请免费的SSL证书，该项目提供了一个叫certbot/certbot-auto的工具获取证书，执行下面命令获取工具：

$wget https://dl.eff.org/certbot-auto $chmod +x certbot-auto

执行下面命令生成生成gitlab.papamk.com的证书，其中--agree-tos表示同意协议，--email 95496875@qq.com为自己的email。

$./certbot-auto --agree-tos --email 95496875@qq.com certonly --webroot -w /opt/gitlab/embedded/service/gitlab-rails/public/ -d gitlab.papamk.com

执行成功后，可通过以下命令查看下证书位置，nginx需要引用这些文件。（一般位于/etc/letsencrypt/live/gitlab.papamk.com/目录）

$./certbot-auto certificates

2.修改/etc/gitlab/gitlab.rb，对外的URL改为https:

external_url 'https://gitlab.papamk.com'

执行重新配置命令以便让新配置生效:

$gitlab-ctl reconfigure

3.修改前面的nginx的gitlab.conf的配置，全部替换成下面的内容（所有需要注意的地方都加了中文注释）：

upstream gitlab-workhorse { server 172.18.147.173:8181; #根据实际情况修改 } ## Redirects all HTTP traffic to the HTTPS host server { ## Either remove "default_server" from the listen line below, ## or delete the /etc/nginx/sites-enabled/default file.

重启nginx:

$sudo service nginx restart

4.定期更新ssl证书
Let's encrypt提供的证书，有效期为90天，到期后执行如下命令即可继续使用：

$./certbot-auto renew

将该命令加入到crontab，每小时刷新一次，就不用担心过期了。先将该命令移到系统目录下：

$sudo mv certbot-auto /usr/bin/certbot-auto

然后执行crontab -e，添加一行：

0 */1 * * * /usr/bin/certbot-auto renew 发送邮件的支持
