Linux中应用程序的安装于管理
一 . rpm安装
1.挂载
光驱里面存放了很多rpm的软件包
光驱在系统中使用时，需要挂载
mount /dev/cdrom /mnt/
cd /mnt
[root@stw mnt]# ls
CentOS_BuildTag GPL LiveOS RPM-GPG-KEY-CentOS-7
EFI images Packages RPM-GPG-KEY-CentOS-Testing-7

[root@stw mnt]# cd Packages
[root@stw Packages]# ls

......
Packages包中存放了很多rpm的软件包
2.rpm包管理命令
显示系统中以RPM方式安装的所有软件列表
rpm -qa
查看某个软件包是否安装
rpm -q vsftpd
或者
rpm -qa | grep vsftpd
查看指定软件包的详细信息

rpm
-i 安装 （内核的更新和安装用-i）
-v 显示详细过程
-h 以“#”显示进度
-e 卸载
-U 更新，如果该软件包未安装的话，则直接安装最新版本
-F 更新，如果未安装旧版本软件包，则放弃安装或更新
–force 强制
–nodeps 去除依赖性关系
卸载（rpm -e 软件包名称）
[root@stw ~]# rpm -e vsftpd
[root@stw ~]# rpm -q vsftpd
package vsftpd is not installed
二 . yum安装
1.yum仓库
yum仓库必须在/etc/yum.repos.d/目录下
cd /etc/yum.repos.d/
rm -rf *
vim server.repo
[a]
name=aa
baseurl=file:///mnt/ （本地安装）
baseurl=http:// （网络安装）
enabled=1
gpgcheck=0（校验完整性，1：开启，0：关闭）
一般网络安装才需要校验
gpgcheck=1（校验完整性，1：开启，0：关闭）
gpgkey =http://加上密钥具体位置
[root@stw ~]# cd /etc/yum.repos.d/
[root@stw yum.repos.d]# ls
CentOS-Base.repo
[root@stw yum.repos.d]# rm -rf *
[root@stw yum.repos.d]# vim server.repo //server可以自己命名
2.yum命令
安装软件包（yum -y install 软件包名）
[root@stw yum.repos.d]# yum -y install httpd
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
a | 3.6 kB 00:00
Package matching httpd-2.4.6-88.el7.centos.x86_64 already installed. Checking for update.
Nothing to do
卸载软件包（yum -y remove 软件包名）
[root@stw yum.repos.d]# yum -y remove httpd
Loaded plugins: fastestmirror, langpacks

安装软件包组（yum -y groupinstall "软件包组 " ）
[root@stw yum.repos.d]# yum -y groupinstall "Development Tools"
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
Maybe run: yum groups mark install (see man yum)
No packages in any requested group available to install or update
卸载软件包组（yum -y group remove “软件包组”）
[root@stw yum.repos.d]# yum -y groupremove "Development Tools"
列出所有已安装的和可用的软件包（yum list）
列出所有已安装的和可用的软件包组（yum group list）
更新软件包（yum update 软件包）
查看yum仓库是否配置成功（yum repolist）
[root@stw yum.repos.d]# yum repolist

Loading mirror speeds from cached hostfile
repo id repo name status
a aa 4,021
repolist: 4,021
三 . dns安装
dnf的使用方法基本上和yum一致（使用前要用yum网络安装dnf）
dnf -y install
dnf -y remove
dnf -y update
[root@stw yum.repos.d]# curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo% Total % Received % Xferd Average Speed Time Time Time CurrentDload Upload Total Spent Left Speed

[root@stw yum.repos.d]# rpm -q dnf
package dnf is not installed
