RHEL7安装配置TigerVNC

TigerVNC使用非加密的链接，默认会被firewalld blocked 掉，想要 vnc正常工作就需要让firewalld开放相应的端口才行。

vnc默认的端口号为5900，而每个vnc window的端口号是： 5900+window_number(or,display_number)

如：systemctl start vncserver-username@:2.service 那么这个vnc window的端口号就是 5902

1. Installing VNC Server

~]# yum install tigervnc-server

2. Configuring VNC Server

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

2.1 修改配置文件vncserver@:1.service，把USER修改为root

[Service]
Type=forking
# 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 || :'

2.2 To make the changes take effect immediately, issue the following command:

~]# systemctl daemon-reload

`2.3 Set the password for the user or users defined in the configuration file.`

~]$ vncpasswd
Password:
Verify:

3. Starting VNC Server

~]# systemctl start vncserver@:1.service

查看端口监听状态：

[root@rusky system]# netstat -an | grep 5901
tcp 0 0 0.0.0.0:5901 0.0.0.0:* LISTEN
tcp6 0 0 :::5901 :::* LISTEN

要关闭服务器上的防火墙。

`4. 使用VNCViewer客户端连接到VNC服务`

`IP:端口或是IP: displayNumber`

或是使用IP:displayNumber来连接

点击Connect，密码为2.3设置的密码。

二、Configuring VNC Server for Two or more Users

配置多个用户来连接到VNC服务器：

Technorati Tags: linux

1. 复制一份配置文件：vncserver@:2.service

~]# cp vncserver@:1.service vncserver@:2.service

2. 修改配置文件：把Home修改为对应的Username:

[Service]
Type=forking
# 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 rusky -c "/usr/bin/vncserver %i"
PIDFile=/home/rusky/.vnc/%H%i.pid
ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'

[Install]

3. 切换到rusky用户，并设置vnc密码

[root@rusky ~]# su - rusky
Last login: Wed Nov 2 12:01:47 CST 2016 on pts/0
[rusky@rusky ~]$ vncpasswd
Password:
Verify:

4. 切换回root账号，启动vncserver@:2.service服务

~]# systemctl start vncserver@:2.service

[root@rusky ~]# netstat -an |grep 590*
tcp        0      0 0.0.0.0:5901            0.0.0.0:*               LISTEN
tcp        0      0 0.0.0.0:5902            0.0.0.0:*               LISTEN
tcp        0      0 192.168.1.202:5901      192.168.1.100:42832     ESTABLISHED
tcp6       0      0 :::5901                 :::*                    LISTEN
tcp6       0      0 :::5902                 :::*                    LISTEN

之后，可使用IP:2或IP:5902进行连接
