Create an RHEL7 system image for OpenStack, openstackrhel7

Create the RHEL7 system image used by OpenStack, set the image, and install XRDP for remote access.

1. Install the RHEL7.2 client in KVM;

2. Set the NIC to dhcp and onboot = yes so that the virtual machine can automatically obtain the IP address;

vim /etc/sysconfig/network-scripts/ifcfg-eth0

Make sure you can connect to the Internet.

3. View The SELinux status:

/usr/sbin/sestatus -v     SELinux status:                 enabled

Enabled indicates that SELinux is enabled.

Disable SELinux:

vim /etc/selinux/config

Set "SELINUX = disabled" and comment out the remaining rows.

Restart the machine.

4. View and disable firewalld

The latest CentOS7/REHL7 firewall has been updated to firewalld.

View the Firewall Status:

systemctl status firewalld.service

Disable Firewall:

systemctl stop firewalld.service

Disable startup:

systemctl disable firewalld.service

5. Install XRDP for remote access:

(1) install the EPEL Library

wget http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpmrpm -ivh epel-release-7-5.noarch.rpm

(2) install xrdp

yum updateyum -y install xrdp tigervnc-server

(3) start:

systemctl start xrdp.service

Enable startup:

systemctl enable xrdp.service

(4) Check whether xrdp is listening for 3389:

netstat -antup | grep xrdp

6. compress the image file and upload it to OpenStack to enable the instance. You can access the image through the Remote Desktop without accident.
