centos7.2系統kvm安裝vnc設置

批量安裝相關軟件：

cd /media/cdrom/Packages

yum --skip-broken --disablerepo=\* --enablerepo=c7-media install *kvm*.rpm *qemu*.rpm *virt*.rpm *vnc*.rpm

 

配置vnc：

cp /lib/systemd/system/[email protected] /etc/systemd/system/vncserver@:1.service

然後打開這個配置文件/etc/systemd/system/vncserver@:1.service替換掉默認用戶名

找到這一行

ExecStart=/sbin/runuser -l <USER> -c "/usr/bin/vncserver %i"

PIDFile=/home/<USER>/.vnc/%H%i.pid

這裏直接用root 用戶登錄，所以替換成

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

PIDFile=/root/.vnc/%H%i.pid

 

重加載 systemd

systemctl daemon-reload

設置vnc密碼

vncpasswd

開啓服務

systemctl enable vncserver@:1.service

systemctl start vncserver@:1.service

 

防火牆設置

firewall-cmd --permanent --add-service vnc-server

systemctl restart firewalld.service

禁止防火牆

systemctl stop firewalld.service

systemctl disable firewalld.service

systemctl stop iptables.service

systemctl disable iptables.service

vnc服務查看

netstat -nulpt | grep vnc

 

網橋配置：

brctl addbr br0 && brctl addif br0 enp133s0f0 &&  ifconfig br0 192.9.200.202  //寫到一行執行，否則ssh連接會斷開

echo 1 > /proc/sys/net/ipv4/ip_forward

brctl show
