yum 出现错误的解决
昨天刚刚安装好CentOS 6.4,本来打算在CentOS安装nagios，可是就在安装准备的环境的时候，用yum命令居然报错，错误代码如下：
[root@Centos yum.repos.d]# yum install -y php httpd gcc glibc glibc-common gd gd-devel php-devel php-mysql mysql mysql-server php-snmp php-pdo perl-DBD-MYSQL php-pear
Loaded plugins: fastestmirror, refresh-packagekit

尝试了以下几种方法
方法一：
将 /etc/yum.conf 文件中的 plugins 设为 0 。
发现失败了，于是尝试了方法二：
yum clean all
发现问题还是没有解决，于是尝试了方法三：
cd /var/lib/rpm/
rm -i __db.*
yum clean all
yum history new
问题是解决
