在安装gitlab时需要保证虚拟机有4G的内存

 问题分析

这个报错是因为未配置yum源，所以需要安装EPEL源：

[root@bogon ~]# yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

Many EPEL packages require the CodeReady Builder (CRB) repository.
It is recommended that you run /usr/bin/crb enable to enable the CRB repository.
