1、安裝CentOS 7

• 下載

http://isoredirect.centos.org/centos/7/isos/x86_64/CentOS-7-x86_64-Minimal-1611.iso

• 安裝

1、在vmware中，Edit->Virtual Network Editor，選擇VMnet8
2、去掉Use local DHCP service to distribute IP address to VMs選項
3、Subnet IP設置為192.168.2.0
4、點擊NAT Settings設置GATEWAY地址：192.168.2.2
5、安裝過程略,注意修改主機名

• 將靜態(tài)、瞬態(tài)或靈活主機名都改為node1

hostnamectl set-hostname node1

• 修改/etc/sysconfig/network-scripts/ifcfg-eth0：（eth0根據實際情況查看網卡名字）

BOOTPROTO="static"
IPADDR=192.168.2.11
NETMASK=255.255.255.0
ONBOOT=yes
GATEWAY=192.168.2.2
DNS1=192.168.2.2

• 重啟

reboot

• 測試

ping www.baidu.com

• 安裝ifconfig

yum upgrade
yum -y install net-tools

• 查看IP

ifconfig

• 修改/etc/hosts

192.168.2.11 node1
192.168.2.12 node2
192.168.2.13 node3
192.168.2.14 node4
192.168.2.15 node5
192.168.2.16 node6

• 安裝vim

yum -y install vim

• 修改/etc/vimrc

set ai          " always set autoindenting on
set nu!
set tabstop=4       " The width of a TAB is set to 4.
                    " Still it is a \t. It is just that
                    " Vim will interpret it to be having
                    " a width of 4.
set shiftwidth=4    " Indents will have a width of 4
set softtabstop=4   " Sets the number of columns for a TAB
set expandtab       " Expand TABs to spaces
set paste

• 拷貝/etc/vimrc到其他節(jié)點

scp /etc/vimrc root@node2:/etc
scp /etc/vimrc root@node3:/etc
scp /etc/vimrc root@node4:/etc
scp /etc/vimrc root@node5:/etc
scp /etc/vimrc root@node6:/etc

• 修改~/.bashrc

alias rm='rm -f'
# alias cp='cp -i'
# alias mv='mv -i'
alias vi='vim'

• 拷貝~/.bashrc到其他節(jié)點

scp /root/.bashrc root@node2:/root
scp /root/.bashrc root@node3:/root
scp /root/.bashrc root@node4:/root
scp /root/.bashrc root@node5:/root
scp /root/.bashrc root@node6:/root

• 關閉防火墻

systemctl stop firewalld.service

• 禁止firewall開機啟動

systemctl disable firewalld.service

• 設置SSH無密碼登陸

# 生成密鑰
ssh-keygen -t rsa

# 將公鑰放入認證文件中
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

# 拷貝認證文件到其他節(jié)點
scp /root/.ssh/authorized_keys root@node2:/root/.ssh/
scp /root/.ssh/authorized_keys root@node3:/root/.ssh/
scp /root/.ssh/authorized_keys root@node4:/root/.ssh/
scp /root/.ssh/authorized_keys root@node5:/root/.ssh/
scp /root/.ssh/authorized_keys root@node6:/root/.ssh/
