linux之便捷安装yum

闲来无事倒腾一下买了半年什么什么东西都没搞的腾讯云，首先一个空空的服务器自己安装那些个玩意是真的累呀，于是准备使用yum，这是一篇简易安装yum的简易教程

1.首先下载yum的压缩包（下面的包不一定是最新的最新的包去http://yum.baseurl.org/download/自己找哦）

下载

wget http://yum.baseurl.org/download/3.2/yum-3.2.28.tar.gz

解压
tar xvf yum-3.2.28.tar.gz（这样解压后的文件会在root中）

2.运行安装

首先在etc中创建yum而配置文件一yum.conf

touch /etc/yum.conf

进入yum的解压目录我的就在root里面（如果不知道文件被解压到哪里了用find -name去找） 

cd /root/yum-3.2.28

运行下面的语句

./yummain.py install yum

3.其他问题（报错）：

报错1： [root@akinlau yum-3.4.3]# ./yummain.py  Traceback (most recent call last): File “./yummain.py”, line 28, in <module> from yum import Errors File “/root/nagios/yum-3.4.3/yum/__init__.py”, line 52, in <module> import config File “/root/nagios/yum-3.4.3/yum/config.py”, line 30, in <module> from parser import ConfigPreProcessor, varReplace File “/root/nagios/yum-3.4.3/yum/parser.py”, line 4, in <module> import urlgrabber ImportError: No module named urlgrabber

报错2： [root@akinlau yum-3.4.3]# ./yummain.py  Traceback (most recent call last): File “./yummain.py”, line 28, in <module> from yum import Errors File “/root/nagios/yum-3.4.3/yum/__init__.py”, line 55, in <module> import rpmsack File “/root/nagios/yum-3.4.3/yum/rpmsack.py”, line 38, in <module> import yum.depsolve File “/root/nagios/yum-3.4.3/yum/depsolve.py”, line 30, in <module> from transactioninfo import TransactionMember File “/root/nagios/yum-3.4.3/yum/transactioninfo.py”, line 32, in <module> from sqlitesack import YumAvailablePackageSqlite File “/root/nagios/yum-3.4.3/yum/sqlitesack.py”, line 26, in <module> import yumRepo File “/root/nagios/yum-3.4.3/yum/yumRepo.py”, line 33, in <module> import sqlitecachec ImportError: No module named sqlitecachec

如果报错如上在：http://rpm.pbone.net/ 中找到自己的系统版本，下载python-urlgrabber，python-pycurl，yum-metadata-parser这3个包

例如：

　首先找到python-pycurl对应包

　运行wget http://rpmfind.net/linux/centos/7.5.1804/os/x86_64/Packages/python-pycurl-7.19.0-19.el7.x86_64.rpm

   在etc中运行 rpm -ivh python-pycurl-7.19.0-19.el7.x86_64.rpm

   其他两个包重复如上步骤

最后yum安装完成~
