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;

}

# Enable gzip compression as per rails guide: http://guides.rubyonrails.org/asset_pipeline.html#gzip-compression

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

# See config/application.rb under “Relative url support” for the list of

# other files that need to be changed for relative url support

location ~ ^/(assets)/ {

root /opt/gitlab/embedded/service/gitlab-rails/public;

# gzip_static on; # to serve pre-gzipped version

expires max;

add_header Cache-Control public;

}

error_page 502 /502.html;

}
