RHEL7.3安装VNC

部署安装VNC

1、yum安装vnc服务

 yum install tigervnc-server 

2、修改vnc配置文件

[root@girl ~]# cp /lib/systemd/system/vncserver@.service /lib/systemd/system/vncserver@:2.service
[root@girl ~]# vim /lib/systemd/system/vncserver@:2.service

将USER替换为root（或者指定的用户）

xecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'
ExecStart=/usr/sbin/runuser -l <USER> -c "/usr/bin/vncserver %i"
PIDFile=/home/<USER>/.vnc/%H%i.pid
ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :

3、重载服务

systemctl daemon-reload

4、设置登录密码

vncpasswd root

5、关闭防火墙（或者允许端口通过）

systemctl stop firewalld.service  #临时关闭
systemctl disable firewalld.service  #永久关闭
或者
 firewall-cmd --permanent --add-service vnc-server #允许vnc通过
 systemctl restart firewalld.service #重启防火墙

6、开启vnc服务

systemctl start vncserver@:2.service

如出现下列报错

[root@girl ~]# systemctl start vncserver@:2.service
Job for vncserver@:2.service failed because a configured resource limit was exceeded. See "systemctl status vncserver@:1.service" and "journalctl -xe" for details.

使用vncserver查看

[root@girl ~]# vncserver 

Warning: girl:1 is taken because of /tmp/.X11-unix/X1
Remove this file if there is no X server girl:1

Warning: girl:2 is taken because of /tmp/.X11-unix/X2
Remove this file if there is no X server girl:2

Warning:girl:3 is taken because of /tmp/.X11-unix/X3
Remove this file if there is no X server girl:3
 

New 'girl:6 (root)' desktop is girl:6

Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/girl:6.log
'

使用rm命令删除相关文件，再次重启vnc服务

 rm  -rf /tmp/.X11-unix/X1
 rm  -rf /tmp/.X11-unix/X2
 rm  -rf /tmp/.X11-unix/X3

7、加入开机启动

[root@girl ~]# systemctl enable vncserver@:2.service
