1、实验环境
虚拟机环境:
- VMware 12 版本虚拟机
网络环境:
- 内网 IP 段:172.16.1.0
- 外网 iP 段(模拟):10.0.0.0
实验基础:(能够上网,有原本yum源)
- m01:外网 IP 10.0.0.61;内网 IP :172.16.1.61
- web01:外网 IP 10.0.0.7;内网 IP :172.16.1.7
Linux版本:
- CentOS Linux release 7.6.1810
- 3.10.0-957.10.1.el7.x86_64
提示:本无需外网,因个人原因而添加,真实环境只需内网即可,有本地yum仓库的可认为是服务端,其他主机作为同样也能像本案例中的web01一样作为客户端
2、实验步骤
2.1、m01:制作本地yum(服务端)
**1)将CentOS 7 的镜像装入CD/DVD中
2)将/mnt目录作为挂载点,挂载(也可挂载其他目录中)然后查看里面的文件
--------------------------------------------------------------
==>命令如下<==
--------------------------------------------------------------
mount /dev/cdrom /mnt/
df -h|grep 'mnt'
cd /mnt/
ll
--------------------------------------------------------------
==>演示如下<==
--------------------------------------------------------------
[root@m01 ~]# mount /dev/cdrom /mnt/
mount: /dev/sr0 写保护,将以只读方式挂载
[root@m01 ~]# df -h|grep 'mnt'
/dev/sr0 4.3G 4.3G 0 100% /mnt
[root@m01 ~]# cd /mnt/
[root@m01 /mnt]#
[root@m01 /mnt]# ll
总用量 686
-rw-rw-r-- 1 root root 14 11月 26 00:01 CentOS_BuildTag
drwxr-xr-x 3 root root 2048 11月 26 00:20 EFI

3)创建安装包存放的目录
--------------------------------------------------------------
==>命令如下<==
--------------------------------------------------------------
mkdir -p /var/ftp/pub/Packages
--------------------------------------------------------------
==>演示如下<==
--------------------------------------------------------------
[root@m01 /mnt]# mkdir -p /var/ftp/pub/Packages
4)复制ISO中的所有文件(时间比较久,需要等待一段时间)完成后查看确认
--------------------------------------------------------------
==>命令如下<==
--------------------------------------------------------------
cp -a /mnt/* /var/ftp/pub
cd /var/ftp/pub/
ls -rtlh
--------------------------------------------------------------
==>演示如下<==
--------------------------------------------------------------
[root@m01 /mnt]# cp -a /mnt/* /var/ftp/pub
[root@m01 /mnt]# cd /var/ftp/pub/
[root@m01 /var/ftp/pub]# ls -rtlh
总用量 320K
-rw-rw-r-- 1 root root 1.7K 12月 10 2015 RPM-GPG-KEY-CentOS-Testing-7
-rw-rw-r-- 1 root root 1.7K 12月 10 2015 RPM-GPG-KEY-CentOS-7
-rw-rw-r-- 1 root root 18K 12月 10 2015 GPL
###省略###
5)安装vsftp服务,启动和设置开机启动
--------------------------------------------------------------
==>命令如下<==
--------------------------------------------------------------
yum install -y vsftpd
systemctl start vsftpd
systemctl enable vsftpd
--------------------------------------------------------------
==>演示如下<==
--------------------------------------------------------------
[root@m01 /var/ftp/pub]# yum install -y vsftpd
###省略###
已安装:
vsftpd.x86_64 0:3.0.2-25.el7
完毕!
[root@m01 /var/ftp/pub]# systemctl start vsftpd
[root@m01 /var/ftp/pub]# systemctl enable vsftpd
Created symlink from /etc/systemd/system/multi-user.target.wants/vsftpd.service to /usr/lib/systemd/system/vsftpd.service.
6)安装createrepo软件包
--------------------------------------------------------------
==>命令如下<==
--------------------------------------------------------------
cd /var/ftp/pub/Packages
yum install -y createrepo
--------------------------------------------------------------
==>演示如下<==
--------------------------------------------------------------
[root@m01 /var/ftp/pub]# cd /var/ftp/pub/Packages
[root@m01 /var/ftp/pub/Packages]# yum install -y createrepo
###省略###
已安装:
createrepo.noarch 0:0.9.9-28.el7
作为依赖被安装:
deltarpm.x86_64 0:3.6-3.el7 python-deltarpm.x86_64 0:3.6-3.el7
完毕!
7)上传并拷贝安装的软件所需要的相关文件到Packges包下(例如oracle安装所需依赖包、docker安装所需依赖包等,这里不需要,可直接跳过)
8)创建Yum仓库(执行过程可能需要很长时间的等待)
--------------------------------------------------------------
==>命令如下<==
--------------------------------------------------------------
cd /var/ftp/pub
createrepo .
#(注意后面的点)
--------------------------------------------------------------
==>演示如下<==
--------------------------------------------------------------
[root@m01 /var/ftp/pub/Packages]# cd /var/ftp/pub
[root@m01 /var/ftp/pub]# createrepo .
Spawning worker 0 with 4021 pkgs
Workers Finished
Saving Primary metadata
Saving file lists metadata
Saving other metadata
Generating sqlite DBs
Sqlite DBs complete
9)清除原有配置缓存,然后缓存yum源(需要一段时间)
--------------------------------------------------------------
==>命令如下<==
--------------------------------------------------------------
yum clean all
yum makecache
--------------------------------------------------------------
==>演示如下<==
--------------------------------------------------------------
[root@m01 /var/ftp/pub]# yum clean all
已加载插件:fastestmirror
正在清理软件源: base epel extras updates

(17/18): updates/7/x86_64/filelists_db | 3.0 MB 00:00:23
元数据缓存已建立
2.2、web01:修改配置文件(客户端)
1)更改Yum配置文件,将不需要的yum配置文件放入备份文件夹中
--------------------------------------------------------------
==>命令如下<==
--------------------------------------------------------------
cd /etc/yum.repos.d/
mkdir bak
ls
mv *repo* bak/
ls
--------------------------------------------------------------
==>演示如下<==
--------------------------------------------------------------
[root@web01 ~]# cd /etc/yum.repos.d/
[root@web01 /etc/yum.repos.d]# mkdir bak
[root@web01 /etc/yum.repos.d]# ls
bak CentOS7-Base-163.repo.1 CentOS-CR.repo CentOS-fasttrack.repo CentOS-Sources.repo epel.repo
CentOS7-Base-163.repo CentOS-Base.repo.backup CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo
[root@web01 /etc/yum.repos.d]# mv *repo* bak/
[root@web01 /etc/yum.repos.d]# ls
bak
2)只保留CentOS-Media.repo配置文件
--------------------------------------------------------------
==>命令如下<==
--------------------------------------------------------------
mv bak/*M* .
#(注意后面的点)
ls
--------------------------------------------------------------
==>演示如下<==
--------------------------------------------------------------
[root@web01 /etc/yum.repos.d]# mv bak/*M* .
[root@web01 /etc/yum.repos.d]# ls
bak CentOS-Media.repo
3)修改CentOS-Media.repo配置文件
--------------------------------------------------------------
==>命令如下<==
--------------------------------------------------------------
vim CentOS-Media.repo
#(需要会使用vim编辑器,若不会,使用下面一种方法)
cat >CentOS-Media.repo <<EOF
[c7-media]
name=CentOS-$releasever - Media
baseurl=ftp://172.16.1.61/pub
gpgcheck=0
enabled=1
gpgkey=ftp://172.16.1.61/pub/RPM-GPG-KEY-CentOS-7
EOF
cat CentOS-Media.repo
--------------------------------------------------------------
==>演示如下<==
--------------------------------------------------------------
[root@web01 /etc/yum.repos.d]# cat >CentOS-Media.repo <<EOF
> [c7-media]
> name=CentOS-$releasever - Media

> gpgcheck=0
> enabled=1
> gpgkey=ftp://172.16.1.61/pub/RPM-GPG-KEY-CentOS-7
> EOF
[root@web01 /etc/yum.repos.d]# cat CentOS-Media.repo
[c7-media]
name=CentOS- - Media
baseurl=ftp://172.16.1.61/pub
gpgcheck=0
enabled=1
gpgkey=ftp://172.16.1.61/pub/RPM-GPG-KEY-CentOS-7
4)测试Yum仓库
--------------------------------------------------------------
==>命令如下<==
--------------------------------------------------------------
yum search docker
--------------------------------------------------------------
==>演示如下<==
--------------------------------------------------------------
[root@web01 /etc/yum.repos.d]# yum search docker
已加载插件:fastestmirror
Loading mirror speeds from cached hostfile
================================================================== 匹配:docker ===================================================================
