使用脚本进行ansible批量主机的免密配置

#!/bin/bash
#在根目录下创建address文件，一行一个ip地址，将所有需要免密的主机ip填入
User=root　　#ssh免密的账户
passWord=123　　#ssh免密主机的密码
address=`cat /address`
rpm -q sshpass &>/dev/null || yum -y install sshpass &>/dev/null　　#检测sshpass软件包是否安装
if [ $? -gt 0 ];then
    YumBuild
    yum -y install sshpass &>/dev/null || (echo "sshpass build error！" && exit)
fi
[ -d ~/.ssh ] || mkdir ~/.ssh;chmod 700 ~/.ssh
echo "正在创建密钥对...."
rm -rf ~/.ssh/id_rsa ~/.ssh/id_rsa.pub　　　#创建密钥文件
ssh-keygen -t rsa -f ~/.ssh/id_rsa -P "" &>/dev/null
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys && chmod 600 ~/.ssh/authorized_keys
for ip in $address　　#调用/address的相关的ip信息进行ping测试，不通则跳过，通则对主机进行免密配置
do
    ping $ip -c1 &>/dev/null
    if [ $? -gt 0 ];then
        echo "$ip无法ping通请检查网络" 
        continue
    fi
    sshpass -p "$passWord" ssh-copy-id -i ~/.ssh/id_rsa.pub -o StrictHostKeyChecking=no ${User}@$ip &>/dev/null
    echo "$ip 密钥分发成功"
done
