今天在yum install 或者yum update的时候都提示段错误(core dumped)，然后终止运行了。

到谷歌上找各种大虾的文章还是无济于事，只好认真查看错误！首先我确定了不是因为Python版本的原因，因为之前安装了一个Python2.7.4。
| 1 | # vim /usr/bin/yum |
查看第一行
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 | #!/usr/bin/python2.6 importsys try: importyum except ImportError: print >> sys.stderr,"""\ There was a problem importing one of the Python modules required to run yum.

第一行是
| 1 | #!/usr/bin/python2.6 |
直接看这个Python2.6是不是有问题
| 1 2 | [root ~]# /usr/bin/python2.6 -V Python 2.6.6 |
正确识别版本号，没问题。在yum clean all 以后都无济于事的时候，我突然想到会不会/etc/yum.repos.d/目录下多了东西？
| 1 2 | [root ~]# ls /etc/yum.repos.d/ CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo soluslabs.repo |
发现里边有一个soluslabs.repo跟我yum命令报错的地方都是一个资源库，看来问题就在这了。
| 1 2 3 | soluslabs | 951 B 00:00 soluslabs/primary | 11 kB 00:00 段错误 (core dumped) |
段错误的上一行是soluslabs，于是我直接rm它
| 1 | # rm -f /etc/yum.repos.d/soluslabs.repo |
然后再clean下
| 1 | # yum clean all |
好滴，我们再回到熟悉的yum update

搞定，收工！
