前言:在通过yum命令安装软件时报错“-bash: yum: 未找到命令”或者 “-bash: /usr/bin/yum: 没有那个文件或目录”或者“-bash: yum: command not found”"-bash: /usr/bin/yum: No such file or directory"报错看没有安装yum命令,通常情况下linux系统会默认安装该命令,应该是yum命令被卸载删除导致。
原因:yum命令被卸载删除
注意:会安装很多组件,如果服务器是生成环境,请务必做好备份或快照,以免安装影响业务。
以Centos7.x和Centos8.x为例。
两种方法亲测有效。
执行如下命令查看是否有安装yum,若返回为空,则表示没安装

rpm -qa |grep yum

解决方法1:(适合Centos7.x)Centos8在下面。
1、下载阿里云的yum安装包安装:

wget  https://mirrors.aliyun.com/centos-vault/7.4.1708/os/x86_64/Packages/yum-3.4.3-154.el7.centos.noarch.rpm
wget  https://mirrors.aliyun.com/centos-vault/7.4.1708/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
wget  https://mirrors.aliyun.com/centos-vault/7.4.1708/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-42.el7.noarch.rpm

2、执行如下命令安装即可正常。

rpm -ivh yum*

解决方法2:(适合Centos7.x
若上面方法操作后还有问题,可参考如下使用163源安装试下。
1、登录服务器执行如下命令下载。

wget  http://mirrors.163.com/centos/7/os/x86_64/Packages/python-urlgrabber-3.10-10.el7.noarch.rpm
wget  http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-cron-3.4.3-168.el7.centos.noarch.rpm
wget  http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-168.el7.centos.noarch.rpm
wget  http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
wget  http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch.rpm
rpm -ivh --force --nodeps python-urlgrabber-3.10-10.el7.noarch.rpm
rpm -ivh --force --nodeps yum-cron-3.4.3-168.el7.centos.noarch.rpm
rpm -ivh --force --nodeps yum-3.4.3-168.el7.centos.noarch.rpm
rpm -ivh --force --nodeps yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
rpm -ivh --force --nodeps yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch.rpm

2、安装后执行yum命令,若能显示信息,则说明安装成功。
注意:若安装过程中出现“no module named yum”报错提示,请执行如下命令即可

wget  http://mirrors.163.com/centos/7/os/x86_64/Packages/python-2.7.5-89.el7.x86_64.rpm

rpm -ivh --force *.rpm --nodeps


Centos8.x误删yum命令后安装方法:
1、如果有dnf命令,则执行如下命令即可安装yum

dnf -y install yum

2、如果dnf命令也被误删除的话请参考如下方法
如下命令下载yum和dnf安装包及依赖包安装即可正常(亲测

下载完后执行命令安装:

rpm -ivh *.rpm --nodeps --force

按装后执行命令yum回车及dnf回车后可以看到能识别了。
执行如下命令更新缓存

yum makecache

更新成功则说明正常,也可以尝试安装一个小工具试下,例如

yum -y install iotop
dnf -y install iotop


也可参考 https://www.cnblogs.com/zjhblogs/p/16979199.html 处理。
题外话:(不要操作,这里只是做个说明)
若要卸载yum命令为:“ rpm -aq|grep yum|xargs rpm -e --nodeps
卸载python:

rpm -qa|grep python|xargs rpm -ev --allmatches --nodeps
whereis python |xargs rm -frv
