CentOS yum时出现“Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=5&arch=i386&repo=addons error ”错误：[root@server mysql-5.0.56]# yum install gcc
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=5&arch=i386&repo=addons error was
[Errno 4] IOError: <urlopen error (-3, '/xe5/x9f/x9f/xe5/x90/x8d/xe8/xa7/xa3/xe6/x9e/x90/xe6/x9a/x82/xe6/x97/xb6/xe5/xa4/xb1/xe8/xb4/xa5')>
Error: Cannot find a valid baseurl for repo: addons
发现原来是没有配置resolv.conf，于是到/etc目录下配置resolv.conf加入nameserver IP：
[root@server mysql-5.0.56]# vi /etc/resolv.conf
nameserver 218.85.157.99
search localdomain
保存resolv.conf，再次运行上面命令就可以。
[root@server mysql-5.0.56]# yum install gcc
