Windows Remote Desktop Connection CentOS 7

1. Installing Tigervnc-server

Yum Install Tigervnc-server

2. setting up the Vncserver server

Copy the file provided by default to the /etc/systemd/system following command:

CP /lib/systemd/system/[email protected]/etc/systemd/system/[email protected]:1. Service

Modify Configuration

vi/etc/systemd/system/vncserver@:1.service  

Replace it with the <USER> user name you want, I use the account root, add parameters to set the resolution -geometry 1280x720 , all the content is as follows

# The Vncserver service unitfile# # Quick howto:#1. Copy thisfileTo/etc/systemd/system/[email protected]:<display>. service#2. Edit <USER>and vncserver parameters appropriately# ("runuser-l <USER>-c/usr/bin/vncserver%i-arg1-arg2")# 3. Run ' Systemctl daemon-Reload ' #4. Run ' systemctl enable [email protected]:<display>.

Reload the configuration:

Systemctl Daemon-reload

If required can be set to boot up:

SYSTEMCTL enable [email protected]:1. Service

3. Setting up a firewall

First decide firewalld whether to start

Firewall-cmd--state

If it is not started, start the firewall first

Systemctl Start Firewalld

Add Port number 5901-5905 exceptions

Firewall-cmd--permanent--zone=public--add-port=5901-5905/tcp

Reload the firewall

Firewall-cmd--reload

You can use the following command to see if the port number is joined

Firewall-cmd--list-all-zones

4. Setting the VNC password

Via SSH, log in to the server with the Oracle user name and execute the following command

Vncserver

The terminal will prompt you to enter the password, as follows

You'll require a password to access your desktops. Password:Verify:Would to enter a view-only Password (y/n)?  'lenmomdesktop:1 (root)' Desktop is lenmomdesktop:1/root/. vnc//root/.vnc/ in/root/.vnc/file is/root/.vnc/lenmomdesktop: 1. Log

If you want to change your password, you can use it vncpasswd . Now that a VNC service is running, but we need to start with the service we just configured, we need to kill the VNC service first and use the following command:

Vncserver-Kill :1

Next, restart the service:

Systemctl Daemon-reload
Systemctl restart [email protected]:1.service

Use the following command to see if the service is running correctly

SYSTEMCTL status [email protected]:1. service-l

If it starts correctly, the output should be:

[Email protected]:1.

If you want to configure multi-user access at the same time, you need to change the above, and [email protected]:1.service [email protected]:2.service then configure the user name, resolution parameters, and then follow the steps above to do it again.
