yum、rpm

yum

本地yum源配置

1.保证光盘链接

2.挂载

[root@localhost test]# mount /dev/sr0 /media
mount: /dev/sr0 is write-protected, mounting read-only
mount: /dev/sr0 is already mounted or /media busy
/dev/sr0 is already mounted on /media

3 备份Cen*

[root@localhost yum.repos.d]# mv Cen* bak
[root@localhost yum.repos.d]# ls
bak

4 创建后缀以.repo结尾的文件，并编辑

[root@localhost yum.repos.d]# vi yum.repo

5 yum clean all

6 yum makecache

网络yum源配置

1 将本地yum源关闭或移入bak中，将CentOS-Base.repo移至yum.repos.d目录下

2.挂载

[root@localhost test]# mount /dev/sr0 /media
mount: /dev/sr0 is write-protected, mounting read-only
mount: /dev/sr0 is already mounted or /media busy
/dev/sr0 is already mounted on /media

3.进入vi /etc/resolv.conf 配置DNS：nameserver=114.114.114.114（域名解析）

4.route -n查看默认路由，若没有默认路由，route add default gw 网关（若没有route，下载 yum install net-tools -y）

5 ping，看网络是否连通

6 yum list：列出yum源里面的所有包，@标识的是已经安装的，没有@的表示没有安装。

[root@localhost yum.repos.d]# yum list |grep vim

7 yum clean all

8 yum makecache

rpm

-i：安装

-e：卸载

–nodeps：不检查依赖

[root@localhost Packages]# rpm -ivh zip-3.0-11.el7.x86_64.rpm
[root@localhost Packages]# rpm -e libestr --nodeps（文件名）

-U：升级||安装

-F：升级

[root@localhost Packages]# rpm -U libestr-0.1.9-2.el7.x86_64.rpm

-qa：查询所有已经安装的包

-qf：查询当前文件属于哪个包

-qi：查看详细描述

-ql：软件安装的详细信息

-qR：查看依赖

[root@localhost Packages]# rpm -qa
[root@localhost bin]# rpm -qf perl
perl-5.16.3-293.el7.x86_64
[root@localhost Packages]# rpm -qi zip
[root@localhost Packages]# rpm -ql zip
[root@localhost Packages]# rpm -qR zip
