Linux 系统为 CentOS Linux release 7.4.1708
手贱、手贱、手贱 删了python 导致yum不可用。百度一大圈,重装yum和python后,老是报各种各样的错。历经磨难,终于自己总结了一套,亲测可用,分享一下。
- 首先卸载现有python
-
rpm -qa|grep python|xargs rpm -ev --allmatches --nodeps #卸载python
-
whereis python |xargs rm -frv ##删除所有残余文件
-
whereis python ##验证删除,返回无结果
-
- 删除现有的yum
-
rpm -qa|grep yum|xargs rpm -ev --allmatches --nodeps #删除yum
-
whereis yum |xargs rm -frv #删除残留文件
-
whereis yum #验证删除完成
-
-
找到下载文件源
首先在这里找到服务器对应的版本,如 7.4.1708 进入这里目录 找到对应版本的rpm,替换下面的文件。 -
下载并安装,注意顺序,先安装python 然后 yum。不然安装后还会报错,重新来一遍。
