Centos 5 的yum源

背景

有使用较老的Centos 5 系统内部安装软件无法正常报错，是由于系统叫老yum源存在问题

处理方法

更换下述yum源，可以将其他repo源文件备份移动到其他目录，添加下述源后重新测试

---

[C5.11-base]

name=CentOS-5.11   

baseurl=http://vault.centos.org/5.11/os/$basearch/gpgcheck=1

#gpgkey= file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5    如果出现下述报错将此行注释

enabled=1

临时解决就是换个不同的镜像，比如：

baseurl= http://archive.kernel.org/centos-vault/5.11/os/$basearch/

如果出现下述报错提示：
