官方上面说并不推荐在CentOS上面安装GitLab，无奈公司的服务器都是CentOS的系统。不过，好在经历了三天才算把GitLab搭建起来，查了N多参考教程，发现一个问题，并不是每个教程都是通用的、总会遇到某些未知的错误是其他作者没有碰到的，毕竟每台服务器的环境是不一样的，问题百出，很是让人很是头痛。
下面总结了自己在CentOS搭建GitLab的教程以及某些错误的解决办法，算是对自己的总结吧！或许那天就用到了......
——安装前准备工作
1）添加epel源
[root@Git ~]# mkdir /tmp/soft/
[root@Git ~]# cd /tmp/soft/
[root@Git soft]# wget Fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
[root@Git soft]# rpm -ivh epel-release-6-8.noarch.rpm
warning: epel-release-6-8.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID 0608b895: NOKEY
Preparing... ########################################### [100%]
1:epel-release ########################################### [100%]
2）配置epel源
[epel]
name=Extra Packages for Enterprise Linux 6 - $basearch
#download.fedoraproject.org域名已经失效
#去掉#号将download.fedoraproject.org变更为dl.fedoraproject.org
baseurl=http://dl.fedoraproject.org/pub/epel/6/$basearch
#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch
failovermethod=priority
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
3）执行yum makecache 更新
[root@Git soft]# yum makecache
