1、安装依赖：
sudo yum install curl policycoreutils openssh-server openssh-clients
sudo systemctl enable sshd
sudo systemctl start sshd
sudo yum install postfix
sudo systemctl enable postfix
sudo systemctl start postfix
sudo firewall-cmd --permanent --add-service=http
sudo systemctl reload firewalld
2、添加gitlab源：
curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash
3、安装gitlab-ce
sudo yum install gitlab-ce
如果您不喜欢通过管道脚本安装存储库，您可以在这里找到整个脚本并手动选择并下载包并使用：
curl -LJO https://packages.gitlab.com/gitlab/gitlab-ce/packages/el/7/gitlab-ce-XXX.rpm/download
rpm -i gitlab-ce-XXX.rpm
4、配置gitlab：
sudo gitlab-ctl reconfigure
至此gitlab安装成功，默认用户名为root。
5、停止gitlab自带的nginx
打开文件$sudo vi /etc/gitlab/gitlab.rb。
将nginx['enable'] = ture改为nginx['enable'] = false
重启gitlab：sudo gitlab-ctl reconfigure。
6、修改gitlab域名：
打开/etc/gitlab/gitlab.rb文件，将external_url参数修改为自己的域名。
7、添加外部nginx的gitlab配置文件：
vim /etc/nginx/conf.d/gitlab.conf
添加以下内容：
upstream gitlab {
# 7.x 版本在此位置
# server unix:/var/opt/gitlab/gitlab-rails/tmp/sockets/gitlab.socket;
# 8.0 位置
server unix://var/opt/gitlab/gitlab-rails/sockets/gitlab.socket;
}
server {
listen *:80;
server_name gitlab.xuwanqiu.com; # 请修改为你的域名
server_tokens off; # don't show the version number, a security best practice
root /opt/gitlab/embedded/service/gitlab-rails/public;
# Increase this if you want to upload large attachments
# Or if you want to accept large git objects over http
client_max_body_size 250m;
# individual nginx logs for this gitlab vhost
access_log /var/log/gitlab/nginx/gitlab_access.log;
error_log /var/log/gitlab/nginx/gitlab_error.log;
location / {
# serve static files from defined root folder;.
# @gitlab is a named location for the upstream fallback, see below
try_files $uri $uri/index.html $uri.html @gitlab;
}
# if a file, which is not found in the root folder is requested,
# then the proxy pass the request to the upsteam (gitlab unicorn)
location @gitlab {
# If you use https make sure you disable gzip compression
# to be safe against BREACH attack
proxy_read_timeout 300; # Some requests take more than 30 seconds.
proxy_connect_timeout 300; # Some requests take more than 30 seconds.
proxy_redirect off;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Frame-Options SAMEORIGIN;
proxy_pass http://gitlab;
}

# WARNING: If you are using relative urls do remove the block below

}
error_page 502 /502.html;
}
