Today, I will talk to you about the steps of installing VNC in Centos7. Many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something according to this article.

[remember: when installing VNC above Centos7, do not change the runlevel. Default is OK]

1. VNC installation

/ / install remote Desktop programs

# yum groupinstall-y "GNOME Desktop"

[some documents modify the runtime level of the Linux system at this step, do not modify it, otherwise there will be unknow errors when installing oracle]

/ / install VNC program # yum install tigervnc-server-y

2. Set the configuration files and services of the VNC program

# cp-a / lib/systemd/system/vncserver@.service / etc/systemd/system/vncserver@:1.service / / this is used by ordinary root users

# cp-a / lib/systemd/system/vncserver@.service / etc/systemd/system/vncserver@:2.service / / this is used by oracle users

/ / configure the above two files # vim / etc/systemd/system/vncserver@:1.service original file [Unit] Description=Remote desktop service (VNC) After=syslog.target network.target [Service] Type=forking ExecStartPre=/bin/sh-c'/ usr/bin/vncserver-kill% I > / dev/null 2 > & 1 | |: 'ExecStart=/usr/sbin/runuser-lingual files * root *-c "/ usr/bin/vncserver% I" PIDFile=/***root * / .vnc/%H%i.pid ExecStop=/bin/sh-c'/ usr/bin/vncserver-kill% I > / dev/null 2 > & 1 | |:'[Install] WantedBy=multi-user.target Note: root user configuration and path in the configuration file If it is an oracle user, PIDFile=/home/oracle continues to edit the configuration file # vim / etc/sysconfig/vncservers VNCSERVERS= "2:oracle" VNCSERVERARGS [2] = "- geometry 1360x768" [I used an oracle user, so I configured a single user]

3. Create oracle users

/ usr/sbin/groupadd oinstall

/ usr/sbin/groupadd dba

/ usr/sbin/useradd-g oinstall-G dba oracle

Passwd oracle / / this is the oracle login password in ssh mode.

4. Set the oracle user password for VNC

# su-oracle

# vncpasswd / / enter the password twice and select N to end

5. Switch to root to start the VNC service

Systemctl start vncserver@:2 # I only use oracle users, so I only start this service

Systemctl enable vncserver@:2 # is set to boot the service automatically

6. VNC is installed here and the installation is complete

7. We download the VNC client and connect remotely on the PC computer.

8. Use the customer you just downloaded to connect to the remote desktop
