服务文件夹自动同步备份脚本

配置文件 .ini

[host]
private_key=E://id_rsa_4096
private_key_pass=23ewrwer
ip=192.1.1.1
username=root
remote_path=/root/vue
local_path=E://logs

private_key 私钥目录
private_key_pass 私钥密码
ip
username ssh用户名
remote_path 远程需要同步的目录
local_path 同步到本地的根目录，远程目录不变放在此根目录

运行方式

命令行运行：
python3 downlaod-params.py 'config13.ini'

Crontab定时执行 py命令同步
