linux环境搭建

sudo免密

root权限下,visudo

root ALL=(ALL) ALL
test ALL=(ALL) NOPASSWD:ALL

vmware复制后网卡设置

打开文件，把eth0的配置删掉，eth1的mac地址copy出来

vim /etc/udev/rules.d/70-persistent-net.rules 

把mac地址替换下

vim /etc/sysconfig/network-scripts/ifcfg-eth0 

ip同步

#!/bin/bash
ip_array="192.168.253.211 192.168.253.212 192.168.253.213 192.168.253.214"
echo "127.0.0.1 localhost" > /tmp/hosts
for ip in ${ip_array}
do
    tmp_host=$(ssh sean@${ip} "hostname")
    echo "${ip} ${tmp_host}" >> /tmp/hosts
done

for ip in ${ip_array}
do
    scp /etc/hosts sean@${ip}:/tmp
done

for ip in ${ip_array}
do
    ssh sean@${ip} "sudo cp /tmp/hosts /etc"
done

ssh免密登陆

sudo vim /etc/ssh/sshd_config

把下列注释去掉

=========================
RSAAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile  .ssh/authorized_keys
=========================

配置authorized_keys文件权限

touch ~/.ssh/authorized_keys
sudo chmod 600 ~/.ssh/authorized_keys
sudo chmod 700 ~/.ssh

生成key并加载到不同机器的文件中

ssh-keygen 
cat ~/.ssh/id_rsa.pub | ssh sean@192.168.253.211 "cat - >> ~/.ssh/authorized_keys"
cat ~/.ssh/id_rsa.pub | ssh sean@192.168.253.212 "cat - >> ~/.ssh/authorized_keys"
cat ~/.ssh/id_rsa.pub | ssh sean@192.168.253.213 "cat - >> ~/.ssh/authorized_keys"
cat ~/.ssh/id_rsa.pub | ssh sean@192.168.253.214 "cat - >> ~/.ssh/authorized_keys"
