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 Loaded plugins: fastestmirror, refresh-packagekit Determining fastest mirrors * base: mirror.esocc.com * extras: mirror.esocc.com * soluslabs: mirror.us1.soluslabs.net * updates: mirror.esocc.com base | 3.7 kB 00:00 base/primary_db | 4.4 MB 00:14 extras | 3.4 kB 00:00 extras/primary_db | 18 kB 00:00 soluslabs | 951 B 00:00 soluslabs/primary | 11 kB 00:00 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 Please install a package which provides this module, or 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: http://yum.baseurl.org/wiki/Faq """ % (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 Loaded plugins: fastestmirror, refresh-packagekit Determining fastest mirrors * base: mirrors.tuna.tsinghua.edu.cn * extras: mirrors.tuna.tsinghua.edu.cn * updates: mirrors.tuna.tsinghua.edu.cn base | 3.7 kB 00:00 base/primary_db | 4.4 MB 00:20 extras | 3.4 kB 00:00 extras/primary_db | 18 kB 00:00 updates | 3.4 kB 00:00 updates/primary_db | 3.9 MB 00:13 Setting up Update Process Resolving Dependencies --> Running transaction check ---> Package bash.x86_64 0:4.1.2-14.el6 will be updated ---> Package bash.x86_64 0:4.1.2-15.el6_4 will be an update ---> Package bind-libs.x86_64 32:9.8.2-0.17.rc1.el6_4.4 will be updated 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 * soluslabs: mirror.eu1.soluslabs.net * updates: 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 (责任编辑：IT) |
