This world there is no problem, the more people playing, and also there is a problem
Like VirtualBox network problems
Today, the teacher let us build Ubuntu Linux virtual machine, because the previous school teacher Lei Fengyang SpringBoot course (highly recommended ah, the students learn Spring Framework do not miss) get docker when he set up a CentOS machine on VirtualBox , there had to Tucao a VMWare, on Hadoop time before a computer installed VMWare, playing games is not good
Too lazy to get along with the teacher's pace NAT LAN connection, and direct play sao the bridge card
It was found that for too long it seems useless bridge card fails, Reference 1: VirtualBox bridge card failure , like installing a bridge driver, eliminating the need for a lot of what DNS resolution (want to understand Linux kernel students do not I learned Kazakhstan)
Recommended installation steps:
Quguan website to download Ubuntu mirror 18.04.4 (latest stable version)
Recommended allocated memory size not less than 1/4 of the native memory, preferably not more than 1/2
Disk allocation 50G, the teacher said to decompile with actual or else so much
At first installation of the system can not be set to the network (so that the network is turned off), because Ubuntu will download a lot of things, but optimized for the user experience, we do not for a long time on ubuntu, would not have
After the installation is complete exit, change the network connection to bridging card, select the name of the interface card you on this function to access external networks
Generally there are three options, Wireless (WIFI) with Wireless, the remaining two is a VPN (start the network proxy to vote for him), the other is a cable network
Done escaped the NAT IP and DNS configuration torture :)
Suddenly feeling programmer happiness is so simple , ha ha
