yum -y update

不工作.... 结果 -bash: /usr/bin/yum: 没有这样的文件或目录

您没有提及在运行上述命令时是否遇到任何错误，但我通过全新安装 CentOS 5.5 并执行“yum erase yum”复制了您的问题。这也删除了包“yum-fastestmirror”和“yum-updatesd”作为依赖项。

然后，我做了以下事情：

# wget http://mirror.symnds.com/distributions/CentOS-vault/5.5/os/x86_64/CentOS/yum-3.2.22-26.el5.centos.noarch.rpm
# wget http://mirror.symnds.com/distributions/CentOS-vault/5.5/os/x86_64/CentOS/yum-fastestmirror-1.1.16-14.el5.centos.1.noarch.rpm
# rpm -Uvh *.rpm

（如果您不想使用我使用的那个，请随意使用您最喜欢的 vault.centos.org 镜像......）

这将“yum”放回去（它需要“yum-fastestmirror”作为依赖项，而“yum-fastestmirror”依赖于“yum”，所以这是我能想到的同时重新安装两者的最快方法)。

之后，“yum”开始工作，我可以使用“yum -y update”（有效地将系统升级到 CentOS 5.10）。
