22) everything is ready to start using the RHEL7.2 operating system

Pop up the user interface and close it.

2. Click any blank space on the screen-Open Terminal 1) Type ifconfig to find more virbr0 network connection ports

Virbr0 is a virtual network connection port. The default is virtual network connection port 0.

Generally, when porting an operating system through a virtual machine, it will be transferred to the network address of nat by default, but you can choose to bridge or have no network connection.

However, due to the existence of the virtual network interface, the slave machine will not take over when the host machine in the dual-computer system. So, uninstalling virbr0 will improve our tool efficiency.

The specific methods are as follows:

View a list of networks:

Delete using "virsh net-destroy default"

Remove from the configuration file

Restart the libvirtd service

Check again and find that virbr0 has been deleted.

2) View the system version through cat / etc/redhat-release, which is displayed as version 7.2

Note: VMware Tools is automatically configured when RHEL 7.2 is installed, so there is no need to configure and install Vmware Tools after installation

3) system state detection

a. Check to see if you can access the Internet.

b. Hostname View and Settin

After the modification is completed, there is no need to restart.

c. Turn off the firewall and set it to power on and turn off automatically

View firewall status [root@localhost~] # systemctl status firewalld

Turn off the firewall and set it to power on and turn off automatically

[root@localhost Desktop] # systemctl stop firewalld [root@localhost Desktop] # systemctl disable firewalld

d. Close selinux

Get the status of the selinux

[root@localhost~] # getenforce

Enforcing

Display as enforcing indicates that it is not closed, display as disabled is closed

Close selinux

[root@localhost~] # sed-I 's/SELINUX=enforcing/SELINX=disabled/'/etc/selinux/config

Restart will not take effect until it is modified.

e. Set CD to boot and mount automatically

Unmount the existing mount first, and then mount it

4) configure local yum source

Back up the files in the yum source directory first

[root@localhost Desktop] # mv / etc/yum.repos.d/redhat.repo / etc/yum.repos.d/redhat.repo.tml

Then create a local yum source

[root@localhost Desktop] # cat > / etc/yum.repos.d/rhel7.repo name=base-rhel7 > baseurl= file:///mnt>enabled=1>gpgcheck=0>EOF

Clear the yum cache [root@localhost Desktop] # yum clean all

Regenerate [root@localhost Desktop] # yum list

5) Test whether yum is configured successfully

Install the test with yum install-y bind
