2. Yum source warehouse installation
To install the source code software package, you need to compile and install. You need to install a compiler that supports C and C++ programming languages, such as gcc, gcc-c++, and make.
If you use rpm to install, you need to install multiple dependency packages first, which will be very cumbersome. Here you can use yum to perform one-click installation
1. Configure local yum source warehouse
mount /dev/cdrom /mnt/ # 把光盘挂载到/mnt目录下
cd /etc/yum.repos.d/
mkdir repos.bak #创建目录
mv *.repo repos.bak #备份文件
vim local.repo
[local] # 仓库类别
name=local # 仓库名称
baseurl=file:///mnt # 指定URL 访问路径为光盘挂载目录
enabled=1 # 开启此yum源，此为默认项，可省略
gpgcheck=0 # 不验证软件包的签名
yum clean all && yum makecache #删除yum缓存并更新
yum clean #可以拆分成两个步骤来进行
yun makecache
2. Yum commonly used operating commands
yum -y install 软件名 # 安装、升级软件包，“-y”选项表示自动确认
yum -y remove 软件名 # 卸载软件包，可自动解决其依赖关系
yum -y update 软件名 #升级软件包
yum list #查询软件包列表
yum list installed #查询系统中已安装的软件包
yum list available #查询仓库中尚未安装的软件包
yum list updates #查询可以升级版本的软件包
yum info 软件名 #查询软件包的描述信息
yum info httpd
yum search [all] 关键词 #根据某个关键词来查找相关的软件包
yum search all httpd
yum whatprovides 命令 #查询命令属于哪个软件包
yum whatprovides netstat
[root@localhost yum.repos.d]# yum list ####查看Yum列表(软件包）
If the software package appears, the installation is successful.
