Set up the experimental environment

Yum software repository

Yum command

Third-party software repository

In rhel8

Then use createrepo-v.

7. Shared software security library Note: build the software store in a host computer, and all hosts can access the software store through the network.

Node1 ip 192.168.1.18

Node2 ip 192.168.1.17

Set up the network of node1

1. Access methods supported by the software repository

File:// Local File ftp:// text transfer Protocol http:// Hypertext transfer Protocol nfts: network File system

two。 The way to build a shared software repository

In node2

1. Install shared software on a host that contains software resources

: yum search ftp

Yum install vsftp (file found above)-y installation

Systemctl start vsftpd

Systemctl enable vsftpd (automatically open)

2 close selinux and firewalld

Selinux:

Getenforce check selinux status Enforcing: selinux enabled

Turn off selinux:

Vim / etc/sysconfig/selinux

Line 7 of the SELINUX=disabled file

Reboot restart the system

Firewalld:

Close firewalld

Systemctl stop firewalld

Systemctl disable firewalld

3. Establish a shared directory

Mkdir / var/ftp/rhel7.6 / var/ftp/software

4. Store shared software resources in a shared directory

Put / var/ftp/software in all third-party software and execute ccreaterepo-v / var/ftp/software

Mount the system installation image resources to / var/ftp/rhel7.6

Mount / dev/cdrom / var/ftp/rhel7.6 is temporarily mounted

Permanently mount the system installation image resources to / var/ftp/rhel7.6

Vim / etc/rc.d/rc.local

Mount / dev/cdrom / var/ftp/rhel7.6

Exit Save

Chmod 755 / etc/rc.d/rc.local

Run it again with the absolute path

/ etc/rc.d/rc.local

Test:

In rhel7_node1:

Firefox ftp://192.168.1.17/software View Resources

Firefox ftp://192.168.1.17/rhel7.6 View Resources

When viewing resources in ftp in node1, sometimes you can't connect in Firefox

There may be the following problems:

1. There is no ping connection between the network and node2.

The vsftpd service is not open in 2.node2

The fire wall in 3.node2 is not closed.

Vim / etc/yum.repos.d/westos.repo

[rhel7.6]

Name=rhel7.6

Baseurl= ftp://192.168.1.17/rhel7.6

Gpgcheck=0

[software]

Name=software

Baseurl= ftp://192.168.1.17/software

Gpgcheck=0

* * yum clean all

Yum repolist to see if resources are available. If so, it means that the experimental environment has been successfully set up in node1 and 2.

Yum search dhcp

Yum install dhcp-y install the dhcp service
