目前只支持Ubuntu和centos，其他操作系统上没测试，应该也行。
若要是Ubuntu，需要修改sudo免密状态：
1
sudo vim /etc/sudoers.d/nopasswd4sudo
添加内容重启：
1
cimerALL=(ALL) NOPASSWD : ALL
修改文件权限：
1
chmod 777 /etc/network/interfaces
使用说明：

python systemControl.py shutdown #关机
python systemControl.py reboot #重启
python systemControl.py changeNetwork ip gateway netmask device #修改ip
