Comprehensive case: establishing a YUM server

Provide the basic software package Base [CD]

Update package is available

Provide other software packages such as nginx, zabbix, docker, hadoop, openstack

Configure the firewall

[root@yum-server] # firewall-cmd-- permanent-- add-service=ftp

[root@yum-server] # firewall-cmd-- reload

Close SELinux

[root@yum-server ~] # setenforce 0

[root@yum-server ~] # vim / etc/sysconfig/selinux

SELINUX=disabled

FTP

[root@yum-server ~] # yum- y install vsftpd

[root@yum-server ~] # systemctl start vsftpd

[root@yum-server ~] # systemctl enable vsftpd

Achieve goal 1: provide the basic software Base

Mount the centos image

[root@yum-server ~] # mkdir / var/ftp/ {centos6u8,centos7u3}

[root@yum-server ~] # mount / home/centos7u3.iso / var/ftp/centos7u3

[root@yum-server ~] # echo "mount / home/centos7u3.iso / var/ftp/centos7u3" > > / etc/rc.d/rc.local

[root@yum-server ~] # chmod + x / etc/rc.d/rc.local

Yum client test

[root@yum-client ~] # rm-rf / etc/yum.repos.d/CentOS-Base.repo

[root@yum-client ~] # vi / etc/yum.repos.d/centos7u3.repo / / add Yum source

[centos7u3]

Name=centos7u3

Baseurl= ftp://192.168.122.202/centos7u3

Gpgcheck=0

Enabled=1

[root@yum-client ~] # yum makecache

[root@yum-client ~] # yum repolist

[root@yum-client ~] # yum- y install wget lftp bash-com* vim-enhanced

Achieve goal 2: provide update

Start yum caching

[root@yum-server ~] # vim / etc/yum.conf

[main]

Cachedir=/var/cache/yum/$basearch/$releasever

Keepcache=1

[root@yum-server ~] # yum clean all

[root@yum-server ~] # yum- y update

[root@yum-server ~] # mkdir / var/ftp/update

[root@yum-server ~] # find / var/cache/yum/x86_64/7/-iname "* .rpm"-exec cp-rf {} / var/ftp/update\

[root@yum-server ~] # yum- y install createrepo

[root@yum-server ~] # createrepo / var/ftp/update

Yum client test

[root@yum-client ~] # rm-rf / etc/yum.repos.d/CentOS-Base.repo

[root@yum-client ~] # vi / etc/yum.repos.d/update.repo

[update]

Name=centos update

Baseurl= ftp://192.168.122.202/update

Gpgcheck=0

Enabled=1

[root@yum-client ~] # yum repolist

Loaded plugins: fastestmirror

Repo id repo name status

Update centos update 75

Repolist: 75

[root@yum-client ~] # yum- y update

Achieve goal 3: provide other software packages such as nginx, zabbix

-- downloadonly

Configure nginx and zabbix feeds

[root@yum-server ~] # vim / etc/yum.repos.d/nginx.repo

[nginx]

Name=nginx repo

Baseurl= http://nginx.org/packages/centos/7/$basearch/

Gpgcheck=0

Enabled=1

Downloadonly

[root@yum-server ~] # yum clean all

[root@yum-server] # yum install nginx-- downloadonly

[root@yum-server ~] # mkdir / var/ftp/ {nginx,zabbix}

[root@yum-server ~] # find / var/cache/yum/x86_64/7/-iname "* .rpm"-exec cp-rf {} / var/ftp/nginx

Create a reopdata:

[root@yum-server ~] # createrepo / var/ftp/nginx / / if you add a new software package, re-create

Yum client test

[root@yum-client ~] # vi / etc/yum.repos.d/nginx.repo

[nginx]

Name=nginx

Baseurl= ftp://192.168.122.202/nginx

Gpgcheck=0

Enabled=1

[root@yum-client ~] # yum repolist

Repo id repo name status

Nginx nginx 1

Update centos update 75

[root@yum-client ~] # yum- y install nginx

The client uses the Yum source:

Add base,update,nginx,zabbix yum Feed

Manual

Shell

Saltstack, Asible, Puppet

Local source: for example, using the installation CD [understanding]

Mount the installation CD (temporary):

[root@tianyun ~] # mount / dev/cdrom / media

Or

[root@tianyun] # mount-o loop centos7u3.iso / media

Add yum Feed

[root@tianyun ~] # vim / etc/yum.repos.d/centos7u3.repo

[centos7u3]

Name=centos7u3

Baseurl= file:///media

Gpgcheck=0

Enabled=1
