1.安装

yum install -y tigervnc-server

2.配置(以root用户登录)

  1. 1.拷贝
  2. cp /lib/systemd/system/[email protected] /lib/systemd/system/[email protected]:1.service
  3. 2.修改配置文件:(主要是修改root用户)
  4. vim /lib/systemd/system/[email protected]:1.service
  5. [Unit]
  6. Description=Remote desktop service (VNC)
  7. After=syslog.target network.target
  8. [Service]
  9. Type=forking
  10. User=root
  11. # Clean any existing files in /tmp/.X11-unix environment
  12. ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'
  13. ExecStart=/sbin/runuser -l root -c "/usr/bin/vncserver %i -geometry 1280x720"
  14. PIDFile=/root/.vnc/%H%i.pid
  15. ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'
  16. [Install]
  17. WantedBy=multi-user.target
  18. 3.加载配置:
  19. systemctl daemon-reload
  20. 4.设置开机启动:
  21. systemctl enable [email protected]:1.service

3.防火墙设置

  1. 查看防火墙状态:
  2. firewall-cmd --state
  3. 关闭防火墙:
  4. systemctl stop firewalld
  5. systemctl disable firewalld
  6. 或者开启防火墙添加5901端口(这里只开启一个端口,如有多个界面可以开启多个端口):
  7. systemctl start firewalld
  8. firewall-cmd --permanent --zone=public --add-port=5901/tcp

4.设置VNC密码

vncserver passwd

5.启动VNC Server

systemctl restart [email protected]:1.service

6.systemctl启动异常解决

  1. [[email protected]wyx system]# systemctl start [email protected]:1.service
  2. Job for [email protected]:1.service failed because the control process exited with error code.
  3. See "systemctl status [email protected]:1.service" and "journalctl -xe" for details.
  4. [[email protected]wyx system]# systemctl status [email protected]:1.service
  5. [email protected]:1.service - Remote desktop service (VNC)
  6. Loaded: loaded (/usr/lib/systemd/system/[email protected]:1.service; enabled; vendor preset:
  7. disabled)
  8. Active: failed (Result: exit-code) since Fri 2018-07-27 19:46:46 CST; 1min 55s ago
  9. Process: 5655 ExecStart=/sbin/runuser -l oracle -c /usr/bin/vncserver %i -geometry
  10. 1280x720 (code=exited, status=1/FAILURE)
  11. Process: 5650 ExecStartPre=/bin/sh -c /usr/bin/vncserver -kill %i > /dev/null 2>&1
  12. || : (code=exited, status=0/SUCCESS)

  如果启动过程中遇到异常,报错已经有进程存在,可以通过以下命令查看到

  1. [[email protected] system]# netstat -antulp | grep 5901
  2. tcp 0 0 0.0.0.0:5901 0.0.0.0:* LISTEN 5008/Xvnc
  3. tcp6 0 0 :::5901 :::* LISTEN 5008/Xvnc
  4. [[email protected] system]# ps -ef | grep vnc
  5. root 5008 1 0 19:45 pts/0 00:00:00 /usr/bin/Xvnc :1 -auth /root/.Xauthority -
  6. desktop wyx.pc.com:1 (root) -fp catalogue:/etc/X11/fontpath.d -geometry 1024x768 -pn
  7. -rfbauth /root/.vnc/passwd -rfbport 5901 -rfbwait 30000
  8. root 5678 1640 0 19:48 pts/0 00:00:00 grep --color=auto vnc

  可以看到,存在vnc进程监听5901端口,此时我们已经可以通过vnc viewer客户端来连接使用服务器,服务启动失败是因为其配    置默认启动第一个用户界面也就是5901(5900+1)端口

  设置我们可以在/usr/bin/vncserver看到$vncPort = 5900 + $displayNumber,这里也可以通过修改5900来更改默认的端口设置

 

  此时,$displayNumber=1

  1. 关闭服务:
  2. vncserver -kill :1
  3. 启动服务
  4. vncserver :n (端口号=5900+n)
  5. 启动时可以同时启动过个进程来分配给不同用户,n不同即可
  6. vncserver :1
  7. vncserver :2
  8. vncserver :3
  9. netstat -antulp | grep 59
  10. tcp 0 0 0.0.0.0:5901 0.0.0.0:* LISTEN 6510/Xvnc
  11. tcp 0 0 0.0.0.0:5902 0.0.0.0:* LISTEN 11064/Xvnc
  12. tcp 0 0 0.0.0.0:5903 0.0.0.0:* LISTEN 12457/Xvnc
  13. tcp 0 0 192.168.0.103:5901 125.71.203.215:65313 ESTABLISHED 6510/Xvnc
  14. tcp6 0 0 :::5901 :::* LISTEN 6510/Xvnc
  15. tcp6 0 0 :::5902 :::* LISTEN 11064/Xvnc
  16. tcp6 0 0 :::5903 :::* LISTEN 12457/Xvnc

  如果我们要使用刚才配置的服务来管理,需要杀死存在的进程

  1. 杀掉已经启动的进程
  2. pkill -9 vnc
  3. 清空配置缓存(删除X1即可,也可以根据需要全部删除)
  4. [[email protected] .X11-unix]# ls /tmp/.X11-unix
  5. X0 X1 X2 X3 X4 X5 X6
  6. 保留config passwd xstartup即可
  7. [[email protected] .vnc]# ls /root/.vnc/
  8. config wyx.pc.com:1.log wyx.pc.com:2.pid wyx.pc.com:3.pid wyx.pc.com:4.pid
  9. passwd wyx.pc.com:2.log wyx.pc.com:3.log wyx.pc.com:4.log xstartup
  10. 现在可以通过systemd管理服务了
  11. systemctl start [email protected]:1.service
  12. netstat -antulp | grep 59
  13. tcp 0 0 0.0.0.0:5901 0.0.0.0:* LISTEN 5611/Xvnc
  14. tcp6 0 0 :::5901 :::* LISTEN 5611/Xvnc
