CentOS yum 段错误 (core dumped)解决方法
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。
[root@lee ~]# yum -y update

段错误 (core dumped)
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。
# 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:
%s
If you cannot solve this problem yourself, please go to
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
直接看这个Python2.6是不是有问题
[root@lee ~]# /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？
[root@lee ~]# 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。
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
# rm -f /etc/yum.repos.d/soluslabs.repo
然后再clean下
# yum clean all
好滴，我们再回到熟悉的yum update
[root@lee ~]# yum -y update

搞定，收工！
另一个解决方法：
使用yum命令安装东西或者yum update时都提示以下错误：
[root@lee ~]# yum update
Loaded plugins: fastestmirror, refresh-packagekit
Loading mirror speeds from cached hostfile
* base: mirrors.tuna.tsinghua.edu.cn
* extras: mirrors.tuna.tsinghua.edu.cn

段错误 (core dumped)
解决方法：
[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
我的系统是CentOS 64位，如果是32位的在赋值libz.so时这么复制
[root@lee ~] cp /usr/lib/libz.so /usr/local/lib/
然后重新yum update就可以了
