centos7 遠程桌面vnc

Centos7 采用mini安裝，如果想遠程桌面，那就需要安裝圖形界面

# yum check-update
# yum groupinstall "X Window System"
# yum install gnome-classic-session gnome-terminal nautilus-open-terminal control-center liberation-mono-fonts
# unlink /etc/systemd/system/default.target
# ln -sf /lib/systemd/system/graphical.target /etc/systemd/system/default.target
# reboot

 

下面開始安裝：
1、安裝tigervnc

# yum install tigervnc-server -y

 

2、從VNC備份庫中復制service文件到系統service服務管理目錄

# cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:1.service

 

3、修改配置文件

# vim /etc/systemd/system/vncserver@:1.service

 #改成root用戶啟動，配置文件看起來這樣的 

[Unit]
Description=Remote desktop service (VNC)
After=syslog.target network.target

[Service]
Type=forking
User=root
# Clean any existing files in /tmp/.X11-unix environment
ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'
ExecStart=/usr/sbin/runuser -l 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

4、啟動服務
重啟進程

# systemctl daemon-reload

 

設置VNC密碼

[root@local ~]# vncpasswd
Password:
Verify:
Would you like to enter a view-only password (y/n)? n
A view-only password is not used

 

設置開機啟動及啟動進程

[root@local ~]# systemctl enable vncserver@:1.service
Created symlink from /etc/systemd/system/multi-user.target.wants/vncserver@:1.service to /etc/systemd/system/vncserver@:1.service.
[root@local ~]# systemctl start vncserver@:1.service
[root@local ~]# systemctl status vncserver@:1.service

5、防火牆設置
關閉防火牆，或者放行5901端口。

6、VNC遠程連接
現在用VNC可以遠程連接了，VNC Server那里填寫的是<服務器IP地址>:5901
