今天deepvps在一个 CentOS VPS 上升级系统时遇到一个问题，yum 报错： 复制代码代码如下: # yum update Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile Traceback (most recent call last): File “/usr/bin/yum”, line 29, in ? yummain.user_main(sys.argv[1:], exit_code=True) File “/usr/share/yum-cli/yummain.py”, line 229, in user_main errcode = main(args) File “/usr/share/yum-cli/yummain.py”, line 104, in main result, resultmsgs = base.doCommands() File “/usr/share/yum-cli/cli.py”, line 339, in doCommands self._getTs(needTsRemove) File “/usr/lib/python2.4/site-packages/yum/depsolve.py”, line 101, in _getTs self._getTsInfo(remove_only) File “/usr/lib/python2.4/site-packages/yum/depsolve.py”, line 112, in _getTsInfo pkgSack = self.pkgSack File “/usr/lib/python2.4/site-packages/yum/__init__.py”, line 591, in pkgSack = property(fget=lambda self: self._getSacks(), File “/usr/lib/python2.4/site-packages/yum/__init__.py”, line 434, in _getSacks self.repos.populateSack(which=repos) File “/usr/lib/python2.4/site-packages/yum/repos.py”, line 223, in populateSack self.doSetup() File “/usr/lib/python2.4/site-packages/yum/repos.py”, line 71, in doSetup self.ayum.plugins.run(‘postreposetup’) File “/usr/lib/python2.4/site-packages/yum/plugins.py”, line 176, in run func(conduitcls(self, self.base, conf, **kwargs)) File “/usr/lib/yum-plugins/fastestmirror.py”, line 181, in postreposetup_hook all_urls = FastestMirror(all_urls).get_mirrorlist() File “/usr/lib/yum-plugins/fastestmirror.py”, line 333, in get_mirrorlist self._poll_mirrors() File “/usr/lib/yum-plugins/fastestmirror.py”, line 376, in _poll_mirrors pollThread.start() File “/usr/lib/python2.4/threading.py”, line 416, in start _start_new_thread(self.__bootstrap, ()) thread.error: can’t start new thread yum 在启动 fastestmirror 插件时出错，是 yum 的一个 bug（http://yum.baseurl.org/ticket/70）。如果停掉 mysqld，yum 一切工作正常。临时解决办法是 yum update 时禁止启动 fastestmirror 插件。 复制代码代码如下: yum –disableplugin=fastestmirror update
