Linux - 关于yum源 file & ftp & http 的三种配置方式
一、环境准备
1、两台Centos服务器:node1、node2
2、配置ip:node1(192.168.2.111)、node2(192.168.2.112)
3、关闭防火墙
systemctl stop firewalld
systemctl disable firewalld
4、禁用SELinux:setenforce 0 && sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
[root@node1 home]# cat /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
二、配置yum源(file版)
1、将操作系统的iso映像文件上传到服务器的/mnt/iso目录下(目录不存在的话,手动创建)
[root@ctos79 ~]# mkdir -p /mnt/iso
2、挂载iso到/dev/cdrum目录(centos7.9该目录下的cdrom是个软连接)
[root@ctos79 ~]# mkdir -p /dev/cdrum
[root@ctos79 ~]# mount -o loop /mnt/iso/CentOS-7-x86_64-DVD-2009.iso /dev/cdrum/
3、创建本地的yum仓库目录 /vat/ftp/pub/os79,将iso文件的内容(/dev/cdrom
目录下的内容)拷贝到yum仓库目录
[root@ctos79 ~]# mkdir -p /var/ftp/pub/os79
[root@ctos79 ~]# cp -a /dev/cdrum/* /var/ftp/pub/os79/
3、配置yum的.repo配置文件(在/etc/yum.repos.d
目录下进行配置)
[root@ctos79 ~]# cat > /etc/yum.repos.d/os79.repo << EOF
> [os79]
> name=Local yum package
> baseurl=file:///var/ftp/pub/os79
> gpgcheck=0
> proxy=_none_
> EOF
4、清理(索引和下载包)缓存,将软件包信息提前在本地索引缓存,用来提高搜索安装软件的速度
[root@ctos79 ~]# yum clean all && yum makecache fast
已加载插件:fastestmirror
正在清理软件源: os79
已加载插件:fastestmirror
Determining fastest mirrors
os79 | 3.6 kB 00:00:00
(1/2): os79/group_gz | 153 kB 00:00:00
(2/2): os79/primary_db | 3.3 MB 00:00:00
元数据缓存已建立
5、显示已配置的软件仓库列表及各个软件仓库的软件包数量
[root@ctos79 ~]# yum repolist
已加载插件:fastestmirror
Loading mirror speeds from cached hostfile
源标识 源名称 状态
os79 Local yum package 4,070
repolist: 4,070
6、以下是实际操作截图
三、配置yum源(ftp版)
1、下载安装vsftpd服务
[root@node1 home]# yum -y install vsftpd
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile

Installed:
vsftpd.x86_64 0:2.2.2-11.el6_4.1
Complete!
2、修改vsftpd配置文件,添加 anon_root=/var/ftp
(注意:实测不需要配置anon_root目录)
[root@node1 home]# cd /etc/vsftpd
[root@node1 vsftpd]# ll
总用量 20
-rw------- 1 root root 125 3月 1 2013 ftpusers
-rw------- 1 root root 361 3月 1 2013 user_list
-rw------- 1 root root 4599 3月 1 2013 vsftpd.conf
-rwxr--r-- 1 root root 338 3月 1 2013 vsftpd_conf_migrate.sh
[root@node1 vsftpd]# vim vsftpd.conf
[root@node1 vsftpd]# tail vsftpd.conf
#
# This directive enables listening on IPv6 sockets. To listen on IPv4 and IPv6
# sockets, you must run two copies of vsftpd with two configuration files.
# Make sure, that one of the listen options is commented !!
#listen_ipv6=YES
pam_service_name=vsftpd
userlist_enable=YES
tcp_wrappers=YES
anon_root=/var/ftp
[root@node1 vsftpd]#
3、修改配置文件之后重启vsftpd服务
# centos6.x
[root@node1 vsftpd]# service vsftpd restart && chkconfig vsftpd on
[root@node1 vsftpd]# chkconfig --list vsftpd
vsftpd 0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭
[root@node1 vsftpd]#
# centos7.x
[root@node1 vsftpd]# systemctl restart vsftpd && systemctl enable vsftpd
4、配置node2的yum配置文件(在/etc/yum.repos.d
目录下)
[root@node2 yum.repos.d]# cat os65.repo
[os65]
name=Local yum package
baseurl=ftp://192.168.56.111/pub/os65
gpgcheck=0
proxy=_none_
enabled=1
5、清理(索引和下载包)缓存,将软件包信息提前在本地索引缓存,用来提高搜索安装软件的速度
yum clean all && yum makecache fast
6、显示已配置的软件仓库列表及各个软件仓库的软件包数量
[root@node2 yum.repos.d]# yum repolist
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
repo id repo name status
os65 Local yum package 6,367
repolist: 6,367
[root@node2 yum.repos.d]#
四、配置yum源(http版)
1、通过wget
获取到大厂的镜像源repo文件,先安装wget
[root@localhost ~]# yum -y install wget
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: mirrors.163.com
* extras: mirrors.163.com
* updates: mirrors.njupt.edu.cn

[root@localhost ~]#
2、获取阿里的repo文件:https://mirrors.aliyun.com/repo/ (可能有加密处理,不能直接wget到Centos-7.repo,访问该网址之后,右键复制了我想要的那个repo的链接)
[root@localhost yum.repos.d]# wget -O CentOS-Base.repo https://mirrors.aliyum.com/repo/Centos-7.repo
