搭建gitlab代码托管仓库（解决centos7无法使用默认数据源问题）

公司的gitlab由于停电，又崩了，每次停电都会崩掉。所以就想到自己学一下搭建gitlab代码中心，后面在搞一个jenkins自动发版学习一下，慢慢搞吧。

在弄的时候，发现Centos7居然在2024年6月31日停止维护了。这就离谱了，他的yum默认数据源也归档了。只能用阿里云等第三方的镜像数据源：

大佬教程地址：CentOS 7 yum无法使用解决方法Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch= - 愚生浅末 - 博客园 (cnblogs.com)

一、配置阿里云第三方yum数据源：

1、首先找到yum的配置文件：

cd /etc/yum.repos.d

找到CentOS-Base.repo文件

直接粘贴吧，懒得改：

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.
#
