如何解决bash: yum: command not found错误

新装的CentOS 7 安装LNMP提示什么“no module  named yum”，然后开始弄YUM，折腾了一大圈，然后把YUM删除了……晕死

解决: -bash: yum: command not found错误

在http://mirrors.163.com/centos/7/os/x86_64/Packages/下载以下RPM安装包

wget http://mirrors.163.com/centos/7/os/x86_64/Packages/python-iniparse-0.4-9.el7.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-3.4.3-150.el7.centos.noarch.rpm
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-40.el7.noarch.rpm

安装一定加上rpm -ivh –force –nodeps 不然会报错

rpm -ivh –force –nodeps python-iniparse-0.4-9.el7.noarch.rpm
rpm -ivh –force –nodeps yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
rpm -ivh –force –nodeps yum-3.4.3-150.el7.centos.noarch.rpm
rpm -ivh –force –nodeps yum-plugin-fastestmirror-1.1.31-40.el7.noarch.rpm
