實驗用的宿主機系統版本
CentOS-7-x86_64-DVD-1503-01.iso
[root@data-1-1 opt]# cat /etc/redhat-release CentOS Linux release 7.1.1503 (Core) [root@data-1-1 opt]# uname -rm 3.10.0-229.el7.x86_64 x86_64 [root@data-1-1 opt]#
系統采用最小化安裝，安裝時為了讓默認網卡名字為eth0，安裝之前傳遞參數
按tab鍵后，末尾加入net.ifnames=0 biosdevname=0
這是通過編輯/etc/default/grub並加入“net.ifnames=0 biosdevname=0 ”到GRUBCMDLINELINUX變量來實現的。
末尾加上vga=791 是為了讓安裝是顯示分辨率高一點，便於顯示全部。否則虛擬機窗口可能顯示不全
關於分辨率參照表如下
系統安裝時的配置：
軟件包選擇：最小化安裝
添加中文語言支持
分區方案：boot分區500MB，swap分區4GB，其余全給根分區。采用標准分區格式，不使用lvm
取消KDUMP
點擊網卡，確認是否已經是eth0
安裝之后修改ip地址為靜態的，同時刪除IPv6相關的行
[root@data-1-1 opt]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 TYPE=Ethernet BOOTPROTO=static DEFROUTE=yes PEERDNS=yes PEERROUTES=yes IPV4_FAILURE_FATAL=no NAME=eth0 DEVICE=eth0 ONBOOT=yes IPADDR=192.168.145.131 GATEWAY=192.168.145.2 DNS1=192.168.145.2 [root@data-1-1 opt]#
命令行執行下面，關閉selinux和防火牆，修改主機名，退出窗口重新登錄
systemctl stop firewalld.service systemctl disable firewalld.service echo 'alias cls="clear screen"'>>.bash_profile echo "alias grep='grep --colour=auto'" >>/etc/profile sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/selinux/config setenforce 0 hostnamectl set-hostname data-1-1
添加dns解析，可以采用公網dns，也可以采用公司內部dns

mlocate包的作用能讓
centos7 使用updatedb和locate命令
基礎rpm包補充

安裝命令自動補全工具
CentOS7官方源默認已經包含bash-completion，直接安裝
yum -y install bash-completion
centos6默認不帶這個包，需要通過epel源安裝
默認情況下，CentOS6官方源不包含bash-completion，需要從epel源中安裝。可直接安裝rpm包 # rpm -ivh https://mirrors.ustc.edu.cn/epel/6/x86_64/bash-completion-1.3-7.el6.noarch.rpm 或者安裝epel的repo源，通過yum安裝 # rpm -ivh https://mirrors.ustc.edu.cn/epel/epel-release-latest-6.noarch.rpm # yum -y install bash-completion
安裝tcpdump，它是個抓包工具，有時候會用到
安裝psmisc包，安裝之后多了 fuser, killall,pstree等命令
yum install tcpdump -y yum install psmisc -y
安裝時間同步工具
yum install ntpdate -y
做時間同步
ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime echo '*/15 * * * * /usr/sbin/ntpdate time1.aliyun.com &>/dev/null' >>/var/spool/cron/root
