#### 前言 ####

这期呢主要说一说Linux中包软件管理相关命令，这一期的命令虽然只有两个。但 软件包的安装和卸载都是我们平常最常用的，需要熟练掌握。

rpm和yum 是CentOS 主要的包软件管理。

两个命令各有用处，①yum需要互联网，yum会去网上的yum源获取所需的软件包

② rpm 操作相对复杂，需要我们做得更多

4、 实践操作

我们下载一个rpm包telnet-server-0.17-66.el7.x86\_64.rpm作为后续实践操作文件

[root@xiezhr test]# wget https://mirrors.aliyun.com/centos/7.9.2009/updates/x86_64/Packages/telnet-server-0.17-66.el7.x86_64.rpm

① 查看rpm包信息

[root@xiezhr test]# rpm -qpi telnet-server-0.17-66.el7.x86_64.rpm
    Name        : telnet-server
    Epoch       : 1
    Version     : 0.17

    Summary     : The server program for the Telnet remote login protocol
    Description :
    Telnet is a popular protocol for logging into remote systems over the
    Internet. The package includes a daemon that supports Telnet remote
    logins into the host machine. The daemon is disabled by default.
    You may enable the daemon by editing /etc/xinetd.d/telnet

② 查看rpm包内容

[root@xiezhr test]# rpm -qpl telnet-server-0.17-66.el7.x86_64.rpm
    /usr/lib/systemd/system/telnet.socket
    /usr/lib/systemd/system/telnet@.service
    /usr/sbin/in.telnetd
    /usr/share/man/man5/issue.net.5.gz
    /usr/share/man/man8/in.telnetd.8.gz
    /usr/share/man/man8/telnetd.8.gz

③ 查看rpm包的依赖环境

[root@xiezhr test]# rpm -qpR telnet-server-0.17-66.el7.x86_64.rpm 
    /bin/sh
    /bin/sh
    /bin/sh

    libc.so.6(GLIBC_2.8)(64bit)
    libutil.so.1()(64bit)
    libutil.so.1(GLIBC_2.2.5)(64bit)
    rpmlib(CompressedFileNames) <= 3.0.4-1

    rtld(GNU_HASH)
    systemd
    systemd
    systemd
    systemd
    rpmlib(PayloadIsXz) <= 5.2-1

④ 安装rpm 包(**参数h 以“\#”显示进度条**)

[root@xiezhr test]# rpm -ivh telnet-server-0.17-66.el7.x86_64.rpm
    Preparing...                          ################################# [100%]
    Updating / installing...
       1:telnet-server-1:0.17-66.el7      ################################# [100%]

⑤ 查询是否安装指定的rpm包

[root@xiezhr test]# rpm -qa telnet-server
    telnet-server-0.17-66.el7.x86_64

⑥ 卸载rpm 包

# 卸载刚才安装的telnet-server 
    [root@xiezhr test]# rpm -e telnet-server 
    # 再次查看rpm包，已经没有了，说明卸载成功了
    [root@xiezhr test]# rpm -qa telnet-server

    Loaded plugins: fastestmirror, langpacks
    Loading mirror speeds from cached hostfile
    epel                         | 4.7 kB  00:00:00     
    extras                       | 2.9 kB  00:00:00     
    nodesource                   | 2.5 kB  00:00:00     
    os                           | 3.6 kB  00:00:00     
    updates                      | 2.9 kB  00:00:00     
    (1/4): epel/7/x86_64/group_gz          |  97 kB  00:00:00     
    (2/4): epel/7/x86_64/updateinfo        | 1.1 MB  00:00:00     
    (3/4): epel/7/x86_64/primary_db        | 7.0 MB  00:00:01     
    (4/4): updates/7/x86_64/primary_db  
    ...

② 查看yum源中是否是否有此软件

[root@xiezhr ~]# yum list telnet-server
    Loaded plugins: fastestmirror, langpacks
    Loading mirror speeds from cached hostfile
    Available Packages
    telnet-server.x86_64                   1:0.17-66.el7                    updates

③ 清空yum 缓存

[root@xiezhr ~]# yum    clean all
    Loaded plugins: fastestmirror, langpacks
    Cleaning repos: epel extras nodesource os updates

这期内容就到这，下期根据思维导图就到Linux用户相关命令的使用了。
