Centos7 tigervnc installation experience

1. If tigervnc is installed for the first time, skip the precautions;

2, if you have installed before, pay attention to the points: view the/tmp/. X11-unix directory, delete the X [1-9] File, note that X0 can not be deleted;

Installation steps:

1,Yum install tigervnc-server;

2. Create a userUseradd 000; if an existing user is used, check whether the. vnc directory exists in/home of the user. If yes, delete it;

3,Cp/lib/systemd/system/vncserver @. service/etc/systemd/system/vncserver @: 1. service. Note that this 1 parameter may not be set here and needs to be determined by the subsequent steps;

4,Vi/etc/systemd/system/vncserver @: 1. service,Edit the content in vncserver @: 1. service:

[...][Service]Type=forking# Clean any existing files in /tmp/.X11-unix environmentExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'#ExecStart=/sbin/runuser -l <USER> -c "/usr/bin/vncserver %i"#PIDFile=/home/<USER>/.vnc/%H%i.pidExecStart=/sbin/runuser -l 000 -c "/usr/bin/vncserver %i"PIDFile=/home/000/.vnc/%H%i.pidExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'

You can leave it unchanged elsewhere;

5. add firewall rules
