CentOS 7.5 安装配置tigervnc-server

系统版本：

1 2	[root@s10 ~]# cat /etc/redhat-release CentOS Linux release 7.5.1804 (Core)

1.安装 Gnome 包

1	[root@s10 ~]# yum groupinstall "GNOME Desktop" "Graphical Administration Tools" -y

2.更新系统的运行级别 （此步骤不是必须）
自动进入图形界面，那么我们需要更改系统的运行级别，输入下面的命令来启用图形界面。

1	[root@s10 ~]# ln -sf /lib/systemd/system/runlevel5.target /etc/systemd/system/default.target

3.安装vnc软件包

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50

4.关闭防火墙

1 2	[root@s10 ~]# systemctl stop firewalld [root@s10 ~]# systemctl disable firewalld

5.复制配置文件

1	[root@s10 ~]# cp /usr/lib/systemd/system/vncserver@.service  /etc/systemd/system/vncserver@:1.service

6.修改配置文件

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64

[root@s10 ~]# vim /etc/systemd/system/vncserver@\:1.service     1 # The vncserver service unit file   2 #   3 # Quick HowTo:   4 # 1. Copy this file to /etc/systemd/system/vncserver@.service   5 # 2.

将第43、44行中的<USER>修改为root或者你想通过vnc登录的账号，如tom 或jerry　如下所示：

1 2	43 ExecStart=/usr/sbin/runuser -l root -c "/usr/bin/vncserver %i"

7.重新加载systemd服务

1	[root@s10 ~]# systemctl daemon-reload

8.设置VNC密码

1 2 3 4 5 6

[root@s10 ~]# vncpasswd Password: Verify: Would you like to enter a view-only password (y/n)? y Password: Verify:

9.启动VNC服务

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

[root@s10 ~]# systemctl start vncserver@\:1.service [root@s10 ~]# 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@s10 ~]# systemctl status vncserver@\:1.service ● vncserver@:1.service - Remote desktop service (VNC)    Loaded: loaded (/etc/systemd/system/vncserver@:1.service; disabled; vendor preset: disabled)    Active: active (running) since 二 2019-04-02 15:02:08 CST; 7s ago   Process: 29678 ExecStart=/usr/sbin/runuser -l root -c /usr/bin/vncserver %i (code=exited, status=0/SUCCESS)   Process: 29675 ExecStartPre=/bin/sh -c /usr/bin/vncserver -kill %i > /dev/null 2>&1 || : (code=exited, status=0/SUCCESS)  Main PID: 29705 (Xvnc)    CGroup: /system.slice/system-vncserver.slice/vncserver@:1.service            ‣ 29705 /usr/bin/Xvnc :1 -auth /root/.Xauthority -desktop s10.sangame.com:1 (root) -fp catalogue:/etc/X11/fontpath.d -geometry 1024x768 -pn -rfbauth /root/.vnc/passwd -rfbport...   4月 02 15:02:04 s10.sangame.com systemd[1]: Starting Remote desktop service (VNC)... 4月 02 15:02:08 s10.sangame.com systemd[1]: Started Remote desktop service (VNC).

查看VNC服务端口启动状态：

1 2 3 4 5 6 7

[root@s10 ~]# netstat  -tunpl |grep  :590 tcp        0      0 0.0.0.0:5900            0.0.0.0:*               LISTEN      4334/qemu-kvm       tcp        0      0 0.0.0.0:5901            0.0.0.0:*               LISTEN      29705/Xvnc          tcp        0      0 0.0.0.0:5903            0.0.0.0:*               LISTEN      5876/qemu-kvm       tcp        0      0 0.0.0.0:5904            0.0.0.0:*               LISTEN      5644/qemu-kvm       tcp        0      0 0.0.0.0:5905            0.0.0.0:*               LISTEN      5710/qemu-kvm       tcp6       0      0 :::5901                 :::*                    LISTEN      29705/Xvnc
