一、安装软件包的三种方法
二、rpm包介绍
三、rpm工具用法
四、yum工具用法
五、yum搭建本地仓库
一、安装软件包的三种方法
- 三种方法：rpm工具（redhat packges manager）、yum工具（Python开发的工具，支持自动安装依赖包）、源码包（源代码，需要编译成可执行的文件后再安装，三种方法中难度系数最大）
- rpm工具安装类似于Windows下.exe文件，安装路径和文件名基本都是固定的
- yum是另一种rpm工具
二、rpm包介绍
- rpm工具使用
1、设置光驱挂载
2、rpm包格式，包名、版本号、发布版本号、平台
3、rpm -ivh rpm包文件 安装
4、rpm -Uvh rpm包文件 升级
5、rpm -e 包名 卸载
6、rpm -qa 查询安装的包
7、rpm -q包名 查询指定包是否安装
8、rpm -qi 包名 查询指定包信息
9、rpm -ql包名 列出包安装的文件
10、rpm -qf 文件绝对路径 查看一个文件是由哪个包安装的
挂载光驱
[root@01 ~]# df -h
文件系统 容量 已用 可用 已用% 挂载点
/dev/sda3 26G 1.2G 25G 5% /
devtmpfs 903M 0 903M 0% /dev
tmpfs 912M 0 912M 0% /dev/shm
tmpfs 912M 8.6M 904M 1% /run
tmpfs 912M 0 912M 0% /sys/fs/cgroup
/dev/sda1 197M 113M 85M 58% /boot
tmpfs 183M 0 183M 0% /run/user/1001
[root@01 ~]# mount /dev/cdrom /mnt/
mount: /dev/sr0 写保护，将以只读方式挂载
[root@01 ~]# cd /mnt/
[root@01 mnt]# ls
CentOS_BuildTag EULA images LiveOS repodata RPM-GPG-KEY-CentOS-Testing-7
EFI GPL isolinux Packages RPM-GPG-KEY-CentOS-7 TRANS.TBL
[root@01 mnt]# cd Packages/
[root@01 Packages]#
- rpm包都存放在Packages/目录下
- 第一部分字符串是包名
- 第二部分-后面是版本号（主版本号，次版本号，小版本或者修正版本）
- 第三部分是发布版本号（el7）
- 第四部分是平台位数（32位和64位，centos7不区分32位和64位）64位向下兼容32位
- 第五部分是后缀名
操作
[root@01 Packages]# ls | tail
yum-plugin-tmprepo-1.1.31-42.el7.noarch.rpm
yum-plugin-verify-1.1.31-42.el7.noarch.rpm
yum-plugin-versionlock-1.1.31-42.el7.noarch.rpm
yum-utils-1.1.31-42.el7.noarch.rpm
zenity-3.22.0-1.el7.x86_64.rpm
zip-3.0-11.el7.x86_64.rpm
zlib-1.2.7-17.el7.x86_64.rpm
zlib-devel-1.2.7-17.el7.x86_64.rpm
zsh-5.0.2-28.el7.x86_64.rpm
zziplib-0.13.62-5.el7.x86_64.rpm
[root@01 Packages]#
三、rpm工具用法
- 安装rpm包：rpm -ivh
- 升级rpm包：rpm -Uvh
- 卸载rpm包：rpm -e zsh（卸载包是会有提示依赖包）
- 查询已经安装的rpm包：rpm -qa
- 参数-q查询指定包是否已经安装过
操作
[root@01 Packages]# pwd
/mnt/Packages
[root@01 Packages]# rpm -ivh zsh-5.0.2-28.el7.x86_64.rpm
准备中... ################################# [100%]
正在升级/安装...
1:zsh-5.0.2-28.el7 ################################# [100%]
[root@01 Packages]#
root@01 Packages]# rpm -e zsh
[root@01 Packages]# rpm -qi zsh-5.0.2-28.el7.x86_64.rpm
未安装软件包 zsh-5.0.2-28.el7.x86_64.rpm
[root@01 Packages]# rpm -qi cryptsetup-libs-1.7.4-3.el7.x86_64.rpm
未安装软件包 cryptsetup-libs-1.7.4-3.el7.x86_64.rpm
[root@01 Packages]# rpm -q cryptsetup-libs-1.7.4-3.el7.x86_64.rpm
未安装软件包 cryptsetup-libs-1.7.4-3.el7.x86_64.rpm
[root@01 Packages]# rpm -qf cryptsetup-libs-1.7.4-3.el7.x86_64.rpm
文件 /mnt/Packages/cryptsetup-libs-1.7.4-3.el7.x86_64.rpm 不属于任何软件包
四、yum工具
- yum list 列出可用的rpm包
- ls /etc/yum.repos.d
- yum search vim 搜索包
- yum install [-y]
- yum grouplist
- yum groupinstall [-y]
- yum remove [-y]
- yum update [-y]
- yum provides "/*/vim"
- rpm安装时如果包有依赖则提示错误，yum则可以自动解决依赖关系
- yum list 第一列是包名，第二列是版本号，第三列是仓库名
- base配置文件在/etc/yum.repos.d/CentOS-Base.repo下
- yum search vim 搜索vim相关的包
- yum install -y 包名，参数-y安装时不再询问是否安装
- yum grouplist列出组
- yum groupinstall -y 包名，安装组件
- yum remove 卸载包
- yum update 不加任何包名则默认升级所有（包括系统）
- yum provides "/*/vim"搜索出所有关于vim命令的包
操作
[root@01 Packages]# rpm -ivh texlive-2012-38.20130427_r30134.el7.x86_64.rpm

五、yum搭建本地仓库
- 挂载镜像到/mnt目录
- cp -r /etc/yum.repos.d /etc/yum.repos.d.bak
- rm -f /etc/yum.repos.d/*
- vim /etc/yum.repos.d/dvd.repo 内容如下
- yum clean all 清空yum
- yum list |less 查看本地yum仓库
- 搭建本地yum仓库便于安装，如果使用rpm安装则提示依赖包
- 使yum保留已经下载的rpm包
- 目的：升级或者重新安装使用
- 操作：修改/etc/yum.conf文件
- yum局域网软件源搭建

# This is the default, if you make this bigger yum won't see if the metadata
# is newer on the remote and so you'll "gain" the bandwidth of not having to
# download the new metadata and "pay" for it by yum not having correct
# information.
# It is esp. important, to have correct metadata, for distributions like
# Fedora which don't keep old packages around. If you don't like this checking
# interupting your command line usage, it's much better to have something
# manually check the metadata once an hour (yum-updatesd will do this).
