破解过程

安装依赖

## 确认 ruby 版本最低为 2.5，否则需要升级
sudo apt-add-repository ppa:brightbox/ruby-ng
sudo apt update
sudo apt install ruby2.5 ruby2.5-dev
 
## 安装 gitlab ruby 环境依赖
sudo gem install gitlab
sudo gem install gitlab-license
sudo gem install openssl

签名

创建 license.rb 文件，并写入一下内容

require 'openssl'
require 'gitlab/license'

key_pair = OpenSSL::PKey::RSA.generate(2048)
  
# Write it to a file to use in the license generation application.

# Extract the public key.
public_key = key_pair.public_key
# Write it to a file to ship along with the main application.

## 执行 license.rb 脚本
ruby license.rb
  
## 执行脚本后目录当前会生成三个文件
# GitLabBV.gitlab-license 为 GitLab License 文件
# license_key.pub 为自签名的公钥
# licens_key 为自签名的私钥

更换证书，添加 license

## 替换证书
# 将上一步生成的公钥文件 license_key.pub 替换 GitLab 服务器中的 /opt/gitlab/embedded/service/gitlab-rails/.license_encryption_key.pub 文件
gitlab-ctl restart  # 重启 GitLab
 
## 删除数据库中原 license 记录
su - gitlab-psql
psql -h /var/opt/gitlab/postgresql -d gitlabhq_production
delete from licenses where id = 1;   # 如果有多条记录就都删掉
 
## 添加 license
# 将上一步生成的 GitLabBV.gitlab-license 导入 GitLab 即可

修改 GitLab 等级

## 默认的 EE 版等级肯定不能满足我们，这一波直接拉满
vim /opt/gitlab/embedded/service/gitlab-rails/ee/app/models/license.rb
--------
restricted_attr(:plan).presence || ULTIMATE_PLAN   #修改
--------
gitlab-ctl restart      # 重启 GitLab
