yum安裝軟體報錯解決辦法

今天本想在centos 的vps上裝一個vpn軟體，試了一下yum，可是報錯了

[root@myvps logs]# yum update

如果停掉 mysqld，yum 一切工作正常。你可以嘗試先停掉mysql，不想停的話試試這個辦法

yum –disableplugin=fastestmirror update
yum –disableplugin=fastestmirror -y install pam-devel

查資料發現這是 yum 的一個 bug（http://yum.baseurl.org/ticket/70），yum 在啟動 fastestmirror 外掛程式時出錯，可以臨時禁止啟動 fastestmirror 外掛程式來緩解我們安裝軟體又不想停掉mysql。
