一、yum命令的基本安装功能
[rootlocalhost ~]# man yum
command is one of: * install package1 [package2] [...] install 包名
yum -y: 安装时自动回答为yes * reinstall package1 [package2] [...] 重新安装 *** 补充rmp命令rpm -ql 包名 查询包安装生成的文件清单 rpm -qf /path/to/file_name: 查询某文件是由哪个软件包生成的
* provides | whatprovides feature1 [feature2] [...]
使用yum来查询软件包生成哪些文件以及文件是由哪个软件包生成的。 * update [package1] [package2] [...] 升级版本可加多个包
* update-to [package1] [package2] [...] 指定升级到哪个版本 * downgrade package1 [package2] [...] 降级 * check-update 安装前检查有哪些可以升级的软件包 * upgrade [package1] [package2] [...]
* upgrade-to [package1] [package2] [...] 这两个命令已经被update取代了 * remove | erase package1 [package2] [...] 清除软件包使用yum来清除包会同时清除它被依赖的包 * search string1 [string2] [...] 只记得部分字符可以进行模糊查询 * groupinstall group1 [group2] [...] 组安装 1 针对RHEL 6 Development tools Server Platform Development Desktop Platform Development 2 针对RHEL 5 Development tools development libraries 安装了这些这些组之后就可以编译rpm包了即将源码制作成二进制格式包 * groupupdate group1 [group2] [...] 升级组 * groupremove group1 [group2] [...] 移除组 * localinstall yum除了可以自动安装外也可以将软件包下载到本地然后手动安装 1RHEL 6
统一使用yum install 来安装即可 2RHEL 5 需要使用yum localinstall 来安装同样手动升级可以使用yum localupdateRHEL6处于兼容性需求也支持这样的用法。 yum安装软件包最大的优势在于可以自动解决依赖关系 -- nogpgcheck
对比rpm包yum即使使用了localinstall也会检查软件包的来源合法性如果密钥无法匹配则下载到本地的软件包也无法使用yum安装故可以使用长选项 --nogpgcheck来避免检查 * history : 查看此前的安装卸载等操作历史 二、yum命令安装实例演示
