centos7.2部署vnc服务记录

不做过多介绍了，下面直接记录下centos7系统下安装配置vncserver的操作记录

1）关闭防火墙 centos的防火墙是firewalld，关闭防火墙的命令 [root@localhost ~]# systemctl stop firewalld.service #停止firewall [root@localhost ~]# systemctl disable firewalld.service #禁止firewall开机启动

[root@localhost ~]# setenforce 0 [root@localhost ~]# getenforce [root@localhost ~]# cat /etc/sysconfig/selinux SELINUX=disabled SELINUXTYPE=targeted

2）安装软件： [root@localhost ~]# yum update [root@localhost ~]# yum groupinstall "GNOME Desktop" "X Window System" "Desktop" [root@localhost ~]# yum install tigervnc-server tigervnc vnc vnc-server

3）配置vnc连接 [root@localhost ~]# cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:1.service 修改/etc/systemd/system/vncserver@:1.service 找到这一行 ExecStart=/sbin/runuser -l <USER> -c "/usr/bin/vncserver %i" PIDFile=/home/<USER>/.vnc/%H%i.pid

这里直接用root 用户登录，所以我替换成 ExecStart=/sbin/runuser -l root -c "/usr/bin/vncserver %i" PIDFile=/root/.vnc/%H%i.pid

如果是其他用户的话比如john替换如下 ExecStart=/sbin/runuser -l john -c "/usr/bin/vncserver %i" PIDFile=/home/john/.vnc/%H%i.pid

由于直接root用户登录，所以配置如下： [root@localhost ~]# cat /etc/systemd/system/vncserver@:1.service ......... [Unit] Description=Remote desktop service (VNC) After=syslog.target network.target

[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 || :'

[Install] WantedBy=multi-user.target

为VNC设密码 [root@localhost ~]# vncpasswd 123456

[root@localhost ~]# vim /etc/libvirt/qemu.conf vnc_password = "123456" vnc_listen = "0.0.0.0"

重加载 systemd [root@localhost ~]# systemctl daemon-reload

启动vnc [root@localhost ~]# systemctl enable vncserver@:1.service [root@localhost ~]# systemctl start vncserver@:1.service

注意，此处关闭了防火墙 如果防火墙开了，需要开通一下规则： [root@localhost ~]# firewall-cmd --permanent --add-service vnc-server [root@localhost ~]# systemctl restart firewalld.service 如果是iptable，则需要在/etc/sysconfig/iptables里添加： -A INPUT -m state --state NEW -m tcp -p tcp --dport 5900:5903 -j ACCEPT

关闭vnc连接 [root@localhost ~]# /usr/bin/vncserver -kill :1

测试vnc连接： [root@localhost ~]# novnc_server --vnc 192.168.1.8:5901 --listen 6081 Warning: could not find self.pem Starting webserver and WebSockets proxy on port 6081 WebSocket server settings: - Listen on :6081 - Flash security policy server - Web server. Web root: /usr/share/novnc - No SSL/TLS support (no cert file) - proxying from :6081 to 192.168.1.8:5901

Navigate to this URL:

http://kvm-server:6081/vnc.html?host=kvm-server&port=6081 #http访问方式

Press Ctrl-C to exit

由于kvm-server的主机名对于ip是112.112.113.56，所以在浏览器里输入： http://112.112.113.56:6081/vnc.html?host=112.112.113.56&port=6081
