Gitlab 搭建

breeze -

为什么？

想要自己搭建一个代码仓库无非是以下几点原因：

  1. 公司内部项目
  2. 自己的项目，但不适合在公网
  3. 大部分的 git 仓库虽然有私有服务，但价格都不便宜，甚至不如一台云服务器来的便宜

配置及安装文档 Gitlab

  • 由于 gitlab 会用到 22 端口端口转发的化就走不了 git clone 的默认配置，且占用内存较高，不推荐使用 docker 进行部署；
  • 由于 gitlab 自带 nginx 默认情况下会与属主机的 nginx 冲突，因此推荐只使用 gitlab 自带的 nginx 进行端口转发；

安装 gitlab 后，启动完成后，修改 admin 页面上的设置可能 500 ，其原因是有些密钥需要重置，原因可能是首次启动未启动完全导致（博主的机子性能不够，导致安装后用默认配置启动出现卡死的情况），使用以下代码尝试修复

# 检查密钥
gitlab-rake gitlab:doctor:secrets

# 根据检查结果 可能需要执行以下内容
# 1 进入 dbconsole 更新密钥，可能要执行很久，耐心等待
gitlab-rails dbconsole
