CentOS7 安装 VNC 使用图形界面远程

安装之前检查下是否已经安装VNC

[[e-mail] ~]# rpm -q tigervnc tigervnc-server 
未安装软件包 tigervnc 
未安装软件包 tigervnc-server 

没有安装的话直接使用yum进行安装

[[e-mail] ~]# yum -y install tigervnc tigervnc-server
......
已安装:
  tigervnc.x86_64 0:1.8.0-13.el7                    tigervnc-server.x86_64 0:1.8.0-13.el7                   

作为依赖被安装:
  fltk.x86_64 0:1.3.4-1.el7    mesa-libGLU.x86_64 0:9.0.0-4.el7    tigervnc-icons.noarch 0:1.8.0-13.el7   

完毕！

复制配置模板并进行配置

[[e-mail] ~]# cp /lib/systemd/system/[e-mail] /etc/systemd/system/[e-mail]:1.service
[[e-mail] ~]# vim /etc/systemd/system/[e-mail]\:1.service 

将配置文件中的<user>改成对应的用户，我这里用root

 41 # Clean any existing files in /tmp/.X11-unix environment
 42 ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'
 43 ExecStart=/usr/sbin/runuser -l <USER> -c "/usr/bin/vncserver %i"
 44 PIDFile=/home/<USER>/.vnc/%H%i.pid
 45 ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'

调整为：

 41 # Clean any existing files in /tmp/.X11-unix environment
 42 ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'
 43 ExecStart=/usr/sbin/runuser -l root -c "/usr/bin/vncserver %i"
 44 PIDFile=/home/root/.vnc/%H%i.pid
 45 ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'

要通知systemd重载此配置文件

[[e-mail] ~]# systemctl daemon-reload

现在为这个用户配置个密码

[[e-mail] ~]# vncpasswd 
Password:
Verify:
Would you like to enter a view-only password (y/n)? y
Password:
Verify:
[[e-mail] ~]# 

设置开机服务自启

[[e-mail] ~]# systemctl enable [e-mail]:1.service
Created symlink from /etc/systemd/system/multi-user.target.wants/[e-mail]:1.service to /etc/systemd/system/[e-mail]:1.service.

启动服务

[[e-mail] ~]# vncserver :1
A VNC server is already running as :1

New 'vijay.jump:2 (root)' desktop is vijay.jump:2

Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/vijay.jump:2.log

[[e-mail] ~]# 

剩下的就是按照VNCwindows客户端了，这个就不多说了，直接网上下载并安装，进去后新建连接，使用Ctrl+n打开配置，填写ip地址及端口号即可；默认端口号是从5901开始；
