The following are instructions on how to install TigerVNC Server on a RedHat Linux workstation so it can be accessed remotely using a VNC Viewer. <\/p>\n\n\n\n

1. Install Tiger VNC Server:<\/strong><\/p>\n\n\n\n

su
yum install tigervnc-server*<\/code><\/p>\n\n\n\n

2. Create configuration file for the VNC Service<\/strong>:<\/p>\n\n\n\n

vi \/etc\/systemd\/system\/vncserver@\\:2.service<\/code><\/code> <\/p>\n\n\n\n

or<\/p>\n\n\n\n

nano \/etc\/systemd\/system\/vnserver@\\:2.service<\/code><\/p>\n\n\n\n

Note: On the configuration file, replace the user, group, and WorkingDirectory for the user that will be access this server remotely. <\/em><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

3. Modify GDM Custom Configuration:<\/strong><\/p>\n\n\n\n

nano \/etc\/gdm\/custom.conf<\/code><\/p>\n\n\n\n

or <\/p>\n\n\n\n

vi \/etc\/gdm\/custom.conf<\/code><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

<\/p>\n\n\n\n

4. Create or Modify the xstartup file: <\/strong><\/p>\n\n\n\n

vi \/home\/ddeocampo\/.vnc\/xstartup<\/code> <\/p>\n\n\n\n

or<\/p>\n\n\n\n

nano \/home\/ddeocampo\/.vnc\/xstartup<\/code><\/p>\n\n\n\n

<\/p>\n\n\n\n

Note: make sure exec \/X11\/xinit\/xinitrc <\/strong> is added to the configuration to prevent the blank screen issue: some people experience a blank screen when connecting to a VNC server. Also, ensure x-window-manager &<\/strong> is also included at the bottom of the configuration file.<\/em><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

<\/p>\n\n\n\n

5.<\/strong> Restart the daemon:<\/strong><\/p>\n\n\n\n

systemctl daemon-reload<\/code><\/p>\n\n\n\n

6.<\/strong> Enable the VNC Service:<\/strong><\/p>\n\n\n\n

systemctl enable vncserver@\\:2.service<\/code><\/p>\n\n\n\n

7. Setup VNC password for user account:<\/strong><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

8. Start or Restart the Service<\/strong><\/p>\n\n\n\n

systemctl start vncserver@\\:2.service<\/code><\/p>\n\n\n\n

or<\/p>\n\n\n\n

systemctl restart vncserver@\\:2.service<\/code><\/p>\n\n\n\n

9. You Can Verify the VNC Service\u2019s Status:<\/strong><\/p>\n\n\n\n

systemctl status vncserver@\\:2.service<\/code><\/p>\n\n\n\n

10.<\/strong> Disable Selinux:<\/strong>

setenforce 0<\/code>
sed -i 's\/enforcing\/disabled\/g' etc\/selinux\/config<\/code><\/p>\n\n\n\n

11. Configure the Selinux Config file<\/strong>:<\/p>\n\n\n\n

vi \/etc\/selinux\/config<\/code><\/p>\n\n\n\n

or<\/p>\n\n\n\n

nano \/etc\/selinux\/config<\/code><\/p>\n\n\n\n

Note: change SELINUX=permissive to SELINUX=disabled:<\/em><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
<\/code><\/pre>\n\n\n\n
12. To Check Selinux Status:<\/strong>
sestatus<\/code><\/p>\n\n\n\n
13. To Find TCP Port(s) the VNCServer is using, use the following command:<\/strong>

ss -tulnp | grep 590*<\/code><\/p>\n\n\n\n
Note: As you can see, Xvnc in this example is configured for 5902 and 5903. Your port can be different but it will start with 590. <\/em><\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
<\/p>\n\n\n\n
14. Open VNC Port(s) on Firewall<\/strong>:
<\/code>
firewall-cmd --permanent --zone=public --add-port=5903\/tcp<\/code><\/p>\n\n\n\n
15. Other commands You May Need:<\/strong><\/p>\n\n\n\n
firewall-cmd --reload   \/\/restarts the firewall daemon<\/em>
sysctl stop firewalld  \/\/stops the firewall daemon<\/em>
systemctl status firewalld \/\/checks the firewall status<\/em>
firewall-cmd --state  \/\/checks the firewall state<\/em><\/code><\/p>\n\n\n\n
16. Or you can install firewall-config to view firewall settings through a GUI interface:<\/strong><\/p>\n\n\n\n
firewall-config <\/code><\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
 17. Start the VNCService<\/strong>:<\/p>\n\n\n\n
systemctl start vncserver@\\:2.service<\/code><\/p>\n<\/body>","protected":false},"excerpt":{"rendered":"
