git
搭建过程
安装
gitlab的安装是很简单的,先下载安装包：
wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-10.2.5-ce.0.el7.x86_64.rpm安装：
rpm -Uvh gitlab-ce-10.2.5-ce.0.el7.x86_64.rpm配置
gitlab内置了nginx的服务，所以默认会占用80和443端口。一般来说，我们做WEB开发，服务器上早就安装了nginx或者apache，把80和443端口给占了，所以需要做些修改防止冲突。
简单的修改端口是不可行的，比如80改成85,当查看gitlab项目时，下图中的项目地址会变成http://git.papamk.com:85/papamk/groupbill这样，看着就不舒服。启用https则在使用过程中则会出现其他的问题。这里不一一论述，直接说明正确的配置方法。
具体步骤：
1.首先确保你的服务器已经有运行nginx，并且该nginx监听宿主机的80和443端口。（如果你原来使用的apache，请通过nginx反向代理到apache，这样apache原来的服务仍然可用）。
2.编辑/etc/gitlab/gitlab.rb:
# 编辑对外的域名（gitlab.papamk.com请添加A记录指向本服务器的公网IP）：
external_url 'http://gitlab.papamk.com/'
# 禁用`gitlab`内置的`nginx`:
nginx['enable'] = false
# 修改成与nginx运行时的用户一致
web_server['external_users'] = ['www']修改监听方式和监听地址(如果nginx与gitlab都在宿主机上，不用改也行；如果nginx在docker中，则需要修改)
gitlab_workhorse['listen_network'] = "tcp"
# 下面的172.18.147.173为本机IP，根据实际情况修改，不能为localhost或者127.0.0.1，否则docker访问不到
gitlab_workhorse['listen_addr'] = "172.18.147.173:8181" 最后执行下面命令让配置生效：
$gitlab-ctl reconfigure3.配置nginx
增加gitlab.conf的配置（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
}
## Normal HTTP host
server {
listen 80;
listen [::]:80 default_server;
server_name gitlab.papamk.com; ## 修改成自己的域名；
server_tokens off; ## Don't show the nginx version number, a security best practice
root /opt/gitlab/embedded/service/gitlab-rails/public;
## See app/controllers/application_controller.rb for headers set
## Individual nginx logs for this GitLab vhost
access_log /home/wwwlogs/gitlab_access.log; # 根据实际情况修改
error_log /home/wwwlogs/gitlab_error.log; # 根据实际情况修改
location / {
client_max_body_size 0;
gzip off;

}
}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 restart4.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 certificates2.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:
$gitlab-ctl reconfigure3.修改前面的nginx的gitlab.conf的配置，全部替换成下面的内容（所有需要注意的地方都加了中文注释）：
upstream gitlab-workhorse {
server 172.18.147.173:8181; #根据实际情况修改
}
## Redirects all HTTP traffic to the HTTPS host
server {
## Either remove "default_server" from the listen line below,
## or delete the /etc/nginx/sites-enabled/default file. This will cause gitlab
## to be served if you visit any address that your server responds to, eg.
## the ip address of the server (http://x.x.x.x/)
listen 0.0.0.0:80;
listen [::]:80 ipv6only=on default_server;
server_name gitlab.papamk.com; ## 改成自己的域名
server_tokens off; ## Don't show the nginx version number, a security best practice
return 301 https://$http_host$request_uri;
access_log /home/wwwlogs/gitlab_access.log; # 根据实际情况修改
error_log /home/wwwlogs/gitlab_error.log; # 根据实际情况修改
}
## HTTPS host
server {
listen 0.0.0.0:443 ssl;
listen [::]:443 ipv6only=on ssl default_server;
server_name gitlab.papamk.com; ## 改成自己的域名

}
}重启nginx:
$sudo service nginx restart4.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
