yum 命令

yum provides

In general, you can search for what package provides a command using the yum provides command:

1
sudo yum provides '*bin/nslookup'

事实上,只要知道该包的某个文件的路径即可:

1
yum provides */X11/extensions/Xrandr.h

详情参见Nslookup: command not found error on RHEL/CentOS 7

yum history

使用回滚彻底删除安装的依赖包:

1
2
yum history list <package>
yum history undo <ID>

关于 RPM 文件

事实上,对于 RPM 文件,除了可以直接使用rpm -i命令进行安装,还可以使用yum install命令安装。使用 yum 的好处是能自动处理依赖关系。例如:

1

4
root@wsxq21:~/shadowsocks-libev/rpm/RPMS/x86_64# rpm -i *.rpm
错误:依赖检测失败:
        zsh 被 shadowsocks-libev-zsh-completion-3.3.0-1.21.gite3c6c80.el7.x86_64 需要
root@wsxq21:~/shadowsocks-libev/rpm/RPMS/x86_64#

而使用 yum 则不然:
