CentOS7.6服务器部署VNC

安装vnc服务器

[root@localhost ~]# yum install tigervnc-server

开启vnc

[root@localhost ~]# vncserver 

You will require a password to access your desktops.

Password:				//输入密码
Verify:					//重复密码
Would you like to enter a view-only password (y/n)? n		//只可看的密码，一般选n
A view-only password is not used
xauth:  file /root/.Xauthority does not exist

New 'localhost.VD:1 (root)' desktop is localhost.VD:1

Creating default startup script /root/.vnc/xstartup
Creating default config /root/.vnc/config
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/localhost.VD:1.log

开启远程端口

[root@localhost ~]# vncserver :1

New 'localhost.VD:1 (root)' desktop is localhost.VD:1

Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/localhost.VD:1.log

查看服务器ip

[root@localhost ~]# ifconfig | grep inet
        inet 10.10.41.43  netmask 255.255.252.0  broadcast 10.10.43.255
        inet6 2400:dd01:1001:1040:3b37:b445:ad5b:ad2f  prefixlen 64  scopeid 0x0
        inet6 fe80::bdd8:8bd:8871:f736  prefixlen 64  scopeid 0x20
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10

关闭防火墙和selinux

1. 关闭防火墙

将firewalld服务设置为disable

[root@localhost ~]# systemctl disable firewalld.service
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

查看状态，成功关闭

[root@localhost ~]# systemctl status firewalld.service
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:firewalld(1)

Apr 22 10:06:35 localhost.VD systemd[1]: Starting firewalld - dynamic firewall daemon...
Apr 22 10:06:37 localhost.VD systemd[1]: Started firewalld - dynamic firewall daemon.
Apr 22 15:31:38 localhost.VD systemd[1]: Stopping firewalld - dynamic firewall daemon...
Apr 22 15:31:39 localhost.VD systemd[1]: Stopped firewalld - dynamic firewall daemon.

2. 关闭selinux

• 临时修改

[root@localhost ~]# setenforce 0

• 永久修改，下次开机生效

[root@localhost ~]# vim /etc/selinux/config 

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled				//开启时显示为enforcing，将其改为disabled

• 查看状态，成功关闭

[root@localhost ~]# getenforce
Permissive

远程访问

打开vnc-viewer，输入需要访问的ip和端口号即可进行访问，本文中使用的ip为：10.10.41.43::5901
