今天在yum install 或者yum update的時候都提示段錯誤(core dumped)，然后終止運行了。
[root@lee ~]# yum -y update

到谷歌上找各種大蝦的文章還是無濟于事，只好認真查看錯誤！首先我確定了不是因為Python版本的原因，因為之前安裝了一個Python2.7.4。
# vim /usr/bin/yum
查看第一行
#!/usr/bin/python2.6
import sys
try:
import yum
except ImportError:
print >> sys.stderr, """\
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
%s

verify that the module is installed correctly.
It's possible that the above module doesn't match the
current version of Python, which is:

the yum faq at:

""" % (sys.exc_value, sys.version)
sys.exit(1)
sys.path.insert(0, '/usr/share/yum-cli')
try:
import yummain
yummain.user_main(sys.argv[1:], exit_code=True)
except KeyboardInterrupt, e:
print >> sys.stderr, "\n\nExiting on user cancel."
sys.exit(1)
第一行是
#!/usr/bin/python2.6
直接看這個Python2.6是不是有問題
[root@lee ~]# /usr/bin/python2.6 -V
Python 2.6.6
正確識別版本號，沒問題。在yum clean all 以后都無濟于事的時候，我突然想到會不會/etc/yum.repos.d/目錄下多了東西？
[root@lee ~]# ls /etc/yum.repos.d/
CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo soluslabs.repo
發現里邊有一個soluslabs.repo跟我yum命令報錯的地方都是一個資源庫，看來問題就在這了。

段錯誤 (core dumped)
段錯誤的上一行是soluslabs，于是我直接rm它
# rm -f /etc/yum.repos.d/soluslabs.repo
然后再clean下
# yum clean all
好滴，我們再回到熟悉的yum update
[root@lee ~]# yum -y update

搞定，收工！
另一個解決方法：
使用yum命令安裝東西或者yum update時都提示以下錯誤：
[root@lee ~]# yum update
Loaded plugins: fastestmirror, refresh-packagekit

段錯誤 (core dumped)
解決方法：
[root@lee ~]# rpm -q zlib zlib-devel
zlib-1.2.3-29.el6.x86_64
zlib-devel-1.2.3-29.el6.x86_64
[root@lee ~]# cp /usr/lib64/lib
Display all 1910 possibilities? (y or n)
[root@lee ~]# cp /usr/lib64/libz.so /usr/local/lib64/
[root@lee ~]# cd /usr/local/lib64/
[root@lee lib64]# ln -sf libz.so libz.so.1
[root@lee lib64]# yum clean all
我的系統是CentOS 64位，如果是32位的在賦值libz.so時這么復制
[root@lee ~] cp /usr/lib/libz.so /usr/local/lib/
然后重新yum update就可以了
