Centos/Redhat লিনাক্স এ yum ইন্সটলার সার্ভার কিভাবে কনফিগার করবেন
Mount Installer ISO
mkdir /mnt/dvd1
mount /dev/sr0 /mnt/dvd1
Check if FTP server is installed
systemctl status vsftpd
systemctl start vsftpd
Install ftp Server. Using rpm as yum is not available yet [default yum needs the internet, kindof]
cd /mnt/dvd1/Packages/
rpm -ivh vsftpd-3.0.2-22.el7.x86_64.rpm
systemctl start vsftpd
systemctl enable vsftpd
Copy rpm installer packages to the FTP server under Packages folder
cp -rv /mnt/dvd1/Packages /var/ftp/pub/
Also, copy the key file for Yum. Key file is to verify the integrity of the packages
cp -rv /mnt/dvd1/RPM-GPG-KEY-CentOS-7 /var/ftp/pub/
mv /var/ftp/pub/RPM-GPG-KEY-CentOS-7 /var/ftp/pub/key
Install Createrepo using rpm -ivh; create repo will help to create package rep database based on the packages on the FTP server
rpm -ivh createrepo-0.9.9-28.el7.noarch.rpm
Create the repp config file on yum server
cd /etc/yum.repos.d/
mkdir old
mv *.repo old/
vim ftp.repo
ftp.repo file content
[ftp]
name=ftp
baseurl=ftp://yumserver/pub/Packages
enabled=1
gpgcheck=1
one line for pointing to the GPG key file - if you want to configure for key based verification
Allow ftp over firewall
firewall-cmd --add-service=ftp --perm
systemctl reload firewalld
systemctl restart firewalld
Again Checking if yum works locally on the server
yum repolist all
yum repolist
yum repolist enabled
yum -y install tree
yum clean
yum clean cache
yum -y install tree
yum repolist enabled
yum repolist
Create Installer Repository Data
cd /var/ftp/pub/Packages/
createrepo .
Configure name for the server
hostnamectl set-hostname yumserver
vim /etc/hosts
192.168.1.100 yumserver
192.168.1.200 yumclient
ip addr
ip addr ens33
use nmtui command or ifconfig to set the IP of the server [when required]
you might want to restart the interface
ifdown ens33; ifup ens33
ping yumserver
ping yumclient
before pinging you might want to see if the ping package is installed and if it is blocked or not
Check if yum server works or not
yum install tree
yum -y install lynx
Configure a Client to use your FTP based yum server
Copy the ftp.repo
scp /etc/yum.repos.d/ftp.repo root@yumclient:/etc/yum.repos.d/
For Windows:
tscp /etc/yum.repos.d/ftp.repo root@yumclient:/etc/yum.repos.d/
Check if the client can access your yum server
yum install tree
yum -y install lynx
