Centos 7.9 yum安装nginx 提示"无可用的包"解决方法

环境:Centos 7.9 X86_64

原因:应该是yum软件版本导致的错误,需要更新yum版本

 

#卸载yum并重新安装

rpm -aq|grep yum|xargs rpm -e --nodeps

 

#下载rpm包(如果官网的包更新版本了,则浏览器打开,下载对应升级后的包就行)

wget http://mirrors.aliyun.com/centos/7/os/x86_64/Packages/yum-3.4.3-168.el7.centos.noarch.rpm
wget http://mirrors.aliyun.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
wget http://mirrors.aliyun.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch.rpm
wget http://mirrors.aliyun.com/centos/7/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpm

 

#安装rpm包

rpm -ivh python-iniparse-0.4-9.el7.noarch.rpm
rpm -ivh yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
rpm -ivh yum-3.4.3-168.el7.centos.noarch.rpm --force --nodeps yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch.rpm

 

 #测试

yum list nginx --showduplicates
