1GitLab簡介

  GitLab時基於Git開源的程式碼倉庫，它基於Rnby on Rails 開發，介面美觀，使用方便 ，如果想在區域網搭建一個遠端Git遠端倉庫，或許GitLab就是不錯的選擇。團隊成員可以利用內建的簡單聊天程式(Wall)進行交流。它還提供一個程式碼片段收集功能可以輕鬆實現程式碼複用，日後有需要的時候進行查詢。

2 建立vi /etc/yum.repos.d/gitlab-ce.repo 檔案

[[email protected]_0_3_centos gitlab]# vi /etc/yum.repos.d/gitlab-ce.repo 

新增下面內容

[gitlab-ce]

name=gitlab-ce

repo_gpgcheck=0

gpgcheck=0

enabled=1

3安裝 yum install gitlab-ce

[[email protected]_0_3_centos gitlab]# yum install gitlab-ce^C

4 查詢狀態可以用  gitlab-ctl tail 

[[email protected]_0_3_centos gitlab]# gitlab-ctl tail

如果出現下面的錯誤說明：1，系統記憶體小了，2，unicorn的埠被佔用

解決：增加至少2G的記憶體配置 ，修改vi /etc/gitlab/gitlab.rb            新增 或修改 unicorn['port'] = 6020

 [[email protected]_0_3_centos gitlab]# gitlab-ctl tail
NING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.
