虚拟机安装完成以后的初始化操作笔记

安装完成以后设置root密码 切换root用户sudo passwdsu root设置vi 命令操作nano /ect/apt/sources.listdeb Index of /ubuntu/ trusty main restricted universe multiversedeb Index of /ubuntu/ trusty-security main restricted universe multiversedeb Index of /ubuntu/ trusty-updates main restricted universe multiversedeb Index of /ubuntu/ trusty-proposed main restricted universe multiversedeb Index of /ubuntu/ trusty-backports main restricted universe multiversedeb-src Index of /ubuntu/ trusty main restricted universe multiversedeb-src Index of /ubuntu/ trusty-security main restricted universe multiversedeb-src Index of /ubuntu/ trusty-updates main restricted universe multiversedeb-src Index of /ubuntu/ trusty-proposed main restricted universe multiversedeb-src Index of /ubuntu/ trusty-backports main restricted universe multiversesudo apt-get install vimalias vi=vimLinux下用ifconfig命令设置IP、掩码、网关 设置IP和掩码ifconfig eth0 192.168.5.40 netmask 255.255.255.0设置网关route add default gw 192.168.5.1查看ipifconfig连接SSH服务apt-get install openssh-server查看服务是否启动ps -ef | grep sshd否则 /etc/init.d/ssh start 在开启root账号以后，在主机上用root用户来连接该ubuntu，发现无法连接。 查了一下，发现是sshd服务默认不支持root用户远程连接， 因此我们需要修改sshd的配置文件/etc/ssh/sshd_config， 将PermitRootLogin由默认的without-password改为yes， 然后用sudo service ssh restart或者sudo /etc/init.d/ssh restart来重新启动sshd服务。 这样我们就可以通过root用户来ssh远程登陆虚拟机内的ubuntu了。
