How to deploy local http yum repository

Installing some RPM packages without WAN network can be painful. Why not deploy a local http yum repository to manage your rpm packages.

Assume we have two host just like this

CentOS 7 Server - 1.2.3.4
CentOS 7 Client - 1.2.3.5

Server

# sync rpm packages
$ cp -ap /media/CentOS/* /data/mylocal

# create local repository info
$ yum -y install createrepo --disablerepo='*' --enablerepo='c7-media'
$ createrepo /data/mylocal

Create local yum repository configuration and Test it

# test the repository
$ yum search vsftp --disablerepo='*' --enablerepo=mylocal

$ yum -y install nginx

$ vim /etc/nginx/conf.d/mylocal.conf
server {
    listen 8090;
    server_name your_server_name;
    root /data/mylocal;
    location / {
    	autoindex on;  # Make Sure this line exist !
    }
}

$ sudo nginx -t 
$ systemctl reload nginx
$ systemctl enable nginx

Consider the only repository is mylocal , you can delete other *.repo saved in /etc/yum.repos.d , which make mylocal as the default repository.

Allow the port you defined in nginx virtual host through iptables.

# port 8090 defined in nginx 
$ iptable -I INPUT -m state --state NEW -p tcp --dport 8090 -j ACCEPT 

Remember to umount the DVD iso .

$ umount /media/CentOS

Add a new repository configuration saved in /etc/yum.repos.d/mylocal .

[mylocal]
name=mylocal
baseurl=http://192.168.50.11:8090    
enabled=1
gpgcheck=0

Set mylocal as default repository and update yum cache.

$ mv CentOS-*.repo /tmp

$ yum clean all && yum makecache

Try to install a rpm package whether the repository run correctly or not.

$ yum install w3m -y

Update Repository

You need to update repository manually, when you want to add some new packages.

Assume you want to add package vsftpd . The package dependence could be solved by yum command.

$ find /var/cache/yum/x86_64/7 -name "*.rpm" -exec cp {} /tmp/vsftpd \;
$ cd /tmp/vsftpd && tar -jcf vsftpd_rpms.tar.bz2 *.rpm

Upload the vsftpd_rpms.tar.bz2 to server , which means the 192.168.50.11, then create repository once again.

$ tar -xf /usr/local/src/vsftpd_rpms.tar.bz2 -C /data/mylocal/Packages
$ createrepo /data/mylocal

BOOM ! Well Done ! You do a great job.
