By opening /etc/sysconfig/vncservers. There are two desktops configured here, one is 1 and the other is 2.
The parameters configured here
VNCSERVERS = " 2:root " VNCSERVERARGS[2]=-geometry 1280 x800 "
As you can see, there are two desktops configured here, one is 1 and the other is 2. There is also the resolution of the remote desktop.
To modify the configuration of vncserver, you must first find the configuration file path.
[root @ jtsyb01longgrise] # which vncserver /usr/bin/vncserver?
Then look at the type of this profile,
[root @ jtsyb01longrise] # file/usr/bin/vncserver/usr/bin/vncserver: a/usr/bin/envperl script text executable file.
Then the basic information you can learn is that you can use text files.
I configured port 80 here by looking up the previously configured port.
[root @ jtsyb 0 1 long rise]# grep " 80 "/usr/bin/vncserver-n 84:" xterm-geometry 80x 24+ 10+ 10-ls-title " $ VNCDESKTOP Desktop " & amp； n”。 222:$ VNC port = 800 1+$ display number； 4 19: If (! bind(S，pack('S n x 12 '，$AF_INET，800 1+$ n)){
You can see from the terminal that the previous port on my side was 800 1. By modifying vncport in line 222 and the number 800 1 in line 4 19, we can save the file after modification.
Restarting the vncserver service successfully modified the port number of vnc.
Finally, you can check the port status:
[root @ jtsyb 0 1 long rise]# PS-ef | grep VNC root 17 134 1 0 may 23？ 00:13: 00/usr/bin/xvnc:1-desktop jtsyb01:1(longrise)-auth/root/. x authority-geometry 1024 x768-rfb wait 30000-rfb auth/root/。 Vnc/passwd -rfbport 8002 -fp directory:/etc/x11/fontpath.d-pn.
You can see that the port is running port 8002.
