CentOS安装配置yum

准备

版本：CentOS 7

安装配置过程

卸载系统自带yum

查看是否存在yum

[root@localhost apps]# rpm -qa | grep yum
yum-plugin-fastestmirror-1.1.31-45.el7.noarch
yum-metadata-parser-1.1.4-10.el7.x86_64
yum-3.4.3-158.el7.centos.noarch

卸载yum

[root@localhost apps]# rpm -e --nodeps yum-plugin-fastestmirror-1.1.31-45.el7.noarch
[root@localhost apps]# rpm -e --nodeps yum-metadata-parser-1.1.4-10.el7.x86_64
[root@localhost apps]# rpm -e --nodeps yum-3.4.3-158.el7.centos.noarch

安装依赖包

下载下面两个依赖包并上传（http://mirrors.163.com/centos/7/os/x86_64/Packages/）

• python-2.7.5-68.el7.x86_64.rpm
• python-iniparse-0.4-9.el7.noarch.rpm

安装

[root@localhost apps]# rpm -ivh python-2.7.5-68.el7.x86_64.rpm python-iniparse-0.4-9.el7.noarch.rpm

yum安装

运行以下命令生成缓存

[root@localhost apps]# yum clean all
[root@localhost apps]# yum makecache

http://mirrors.aliyuncs.com/centos/7/os/x86_64/repodata/repomd.xml: [Errno 14] curl#6 - “Could not resolve host: mirrors.aliyuncs.com; 未知的错误”

CentOS 7默认没有开启网络连接，可以设置相关配置(/etc/sysconfig/network-scripts/ifcfg-ens33)

ONBOOT=yes #启用网络连接
BOOTPROTO=none
IPADDR=172.16.105.129
NETMASK=255.255.255.0
GATEWAY=172.16.105.2
DNS1=8.8.8.8
DNS2=8.8.4.4

重启服务并ping测试

[root@localhost apps]# service network restart
[root@localhost apps]# ping www.baidu.com
