1, 要以界面化方式访问服务器,首先要确认目标服务器安装了图形化环境,Linux系统下常见的桌面环境有GNOME和KDE,这里安装GNOME桌面,执行命令如下:
yum -y groupinstall "GNOME Desktop"
2,安装vncserver服务
yum install -y tigervnc-server tigervnc
cp /lib/systemd/system/[email protected] /etc/systemd/system/[email protected]:1.service
#替换文件中的两行,其实就是将<user>换成root
vi /etc/systemd/system/[email protected]:1.service
ExecStart=/usr/sbin/runuser -l <USER> -c "/usr/bin/vncserver %i"
PIDFile=/home/<USER>/.vnc/%H%i.pid
改为下面的:
ExecStart=/sbin/runuser -l root -c "/usr/bin/vncserver %i"
PIDFile=/root/.vnc/%H%i.pid
1) 关闭防火墙
centos的防火墙是firewalld,关闭防火墙的命令
[[email protected] ~]# systemctl stop firewalld.service #停止firewall
[[email protected] ~]# systemctl disable firewalld.service #禁止firewall开机启动
或
如果防火墙开了,需要开通一下规则:
[[email protected] ~]# firewall-cmd --permanent --add-service vnc-server
[[email protected] ~]# systemctl restart firewalld.service
[[email protected] ~]# setenforce 0
[[email protected] ~]# getenforce
[[email protected] ~]# cat /etc/sysconfig/selinux //关闭selinux
SELINUX=disabled
#注意这个密码是登陆vnc时候要用的
为VNC设密码(比如密码设置为123456)
[[email protected] ~]# vncpasswd
Password:
Verify:
Would you like to enter a view-only password (y/n)? n
#注意表示"是否输入一个只能查看的密码,选择否",否则连接vnc会出现黑屏
A view-only password is not used
New ‘localhost.localdomain:1 (bin.wang)‘
desktop is localhost.localdomain:1
Creating default startup script
/root/.vnc/xstartup

/root/.vnc/xstartup
Log file is
/root/.vnc/localhost.localdomain:1.log
#这次的端口号是1,
systemctl daemon-reload
systemctl enable [email protected]:1.service
systemctl start [email protected]:1.service
yum install –y net-tools
netstat -na | grep 5901 //检查端口
[[email protected] ~]#
netstat -na | grep 5901

在windows下载vncvivewer,安装,打开,在ip中输入:
10.81.1.158:1 (ip+端口号) 在passwd中输入:刚才设置的vnc密码123456。 即可登陆
再打开一个的话,输入vncserver
[[email protected] ~]# vncserver
New ‘db:2 (root)‘ desktop is db:2
Starting applications specified in
/root/.vnc/xstartup
Log file is /root/.vnc/db:2.log
在ip中输入:10.81.1.158:2
