标签：1.3 gateway 1.5 Fix 设置 tab补全 删掉 get 网络
开启CPU虚拟化
按到install CentOS7 按下tab 输入net.ifnames=0 biosdevname=0
先来一段文档v1
===============================================================================================
# 第一个里程碑：重启完成之后，登录系统 #
[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0
TYPE=Ethernet
BOOTPROTO=dhcp
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=eth0
UUID=4bf2af89-5f6d-4979-83e9-df6ce1c3cc41
DEVICE=eth0
ONBOOT=no
# 第二个里程碑： 删掉多余的行，只留以下内容 #
TYPE=Ethernet
BOOTPROTO=dhcp
NAME=eth0
DEVICE=eth0
ONBOOT=no
# 第三个里程碑：在以上基础上，继续配置 #
# 红色为修改和增加部分
# 以下代码为优化后的网卡全部配置 #
TYPE=Ethernet
BOOTPROTO=none #取消dhcp
NAME=eth0
DEVICE=eth0
ONBOOT=yes #设置开机启动
IPADDR=10.0.0.11 #IP地址
NETMASK=255.255.255.0 #子网掩码
GATEWAY=10.0.0.254 #网关
DNS1=223.5.5.5 #DNS
# 第四个里程碑：重启网络服务 #
systemctl restart network
# 说明 ：与/etc/init.d/network restart 效果一致
# 第五个里程碑：检查 ping 一下网关10.0.0.254测试网络连通性 #
ping 10.0.0.254 -c2
ping www.baidu.com
到这里，ok，可以愉快的使用xshell了
# 登录xshell开始优化 #
systemctl disable firewalld.service
systemctl stop firewalld
setenforce 0
sed -i ‘s#SELINUX=enforcing#SELINUX=disabled#g‘ /etc/selinux/config
# 修改完成后为红色部分 #
vi /etc/ssh/sshd_config
79行： GSSAPIAuthentication no
115行： UseDNS no
# 重启ssh #
systemctl restart sshd
vi /etc/hosts
# 增加2行
10.0.0.11 controller
10.0.0.31 compute1
hostnamectl set-hostname controller
# 使用光盘搭建本地yum源
点击这个小的 
再单击连接
umount /mnt
cd /etc/yum.repos.d/
mkdir test -p
\mv *.repo test
echo ‘[local]
name=local
baseurl=file:///mnt
gpgcheck=0‘ >local.repo
mount /dev/cdrom /mnt
yum makecache
# 关闭网卡图形化设置模式 #
systemctl stop NetworkManager.service
systemctl disable NetworkManager.service
# 下载tab补全命令 #
yum install -y bash-completion.noarch
# 下载 常用命令 #
yum install -y net-tools vim lrzsz wget tree screen lsof tcpdump
#禁用邮件服务
systemctl stop postfix.service
systemctl disable postfix.service
# 至此；模板机优化完成；关机开始克隆 #
shutdown -h now
===============================================================================================
至上可以重启完成后运行脚本 。可以再第一次重启完成后，连接上光盘，直接运行该脚本
脚本内容如下
