linux下yum錯誤：[Errno 14] problem making ssl connection Trying other mirror.

今天是要yum命令安裝EPEL倉庫后

yum install epel-release

突然發現yum安裝其他的軟件出錯。

錯誤：
[Errno 14] problem making ssl connection Trying other mirror.
Trying other mirror
Error: Cannot retrieve repository metadata (repomd.xml) for repository: xxxx. Please verify its path and try again

於是去網上查了查，發現許多解決方法。似乎是ssl證書的原因，最終選擇

[root@redhat2 ~]# cd /etc/yum.repos.d/
[root@redhat2 yum.repos.d]# ls
CentOS6-Base-163.repo  epel.repo（修改他）  epel-testing.repo
[root@redhat2 yum.repos.d]# pwd
/etc/yum.repos.d
[root@redhat2 yum.repos.d]# 

vim /etc/yum.repos.d/epel.repo

[epel]
name=Extra Packages for Enterprise Linux 6 - $basearch
baseurl=http://download.fedoraproject.org/pub/epel/6/$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

將baseurl注釋去掉，為mirrorlist加上注釋。然后將enabeld=1變為0，禁用ssl證書驗證。

找到了兩種方法（都使用了）：

yum install ca-certificates
yum update curl

然后再將enable設置為1即可
