使用两个简单的shell脚本实现搭建ansible

目录

1.环境规划：

2.脚本my_ssh.sh

3.脚本my_ansible.sh

1.环境规划：

暂时没有写入地址映射和配置主机名的配置，如需要请自行添加！！！

2.脚本my_ssh.sh

完成ssh公钥的创建和复制公钥文件以及ssh密钥登录的测试

#echo "开始修改地址映射"
#
#for ((i=0;i<${#ssh_hosts[*]};i++));do
#	sed -i '/^'"${ssh_hosts[$i]}"'/d' /etc/hosts
#	echo "尝试连接: ${ssh_networkname[$i]}"
#	timeout 5 ssh root@${ssh_networkname[$i]} "echo ${ssh_networkname[$i]}: 'This is success!'"
#	if [[ $? -ne 0 ]];then
#		echo "添加地址映射:${ssh_hosts[$i]} ${ssh_networkname[$i]}"
#		echo "${ssh_hosts[$i]} ${ssh_networkname[$i]}" >> /etc/hosts
#	fi

3.脚本my_ansible.sh

完成chrony时间服务的配置和ansible工具的安装
