used to ssh to exe cmd or scp file
Project description
ssh
安装
pip3 install python3-ssh
用法
is_sshable 用于判断服务器是否可以ssh
如下所示
from ssh.ssh import SSHClient
if __name__ == '__main__':
ssh = SSHClient(ip="192.168.1.2", port=22, username="root", password="xxxx")
print(ssh.is_sshable)
执行结果:
True
其中在建立ssh连接时,默认超时时间为10秒,通常情况下,10超时时间是够了的,但当网络环境确实很差而且无法优化网络环境的情况下,也可以设置连接超时的,如下即将超时时间修改为30秒
from ssh.ssh import SSHClient
if __name__ == '__main__':
ssh = SSHClient(ip="192.168.1.2", port=22, username="root", password="xxxx",connect_timeout=30)
print(ssh.is_sshable)
wait_for_sshable 设置超时等待服务器可以ssh
- 对于新建的虚拟机,可以使用等待可以ssh,并可以设置超时,如下示例中 192.168.1.254 为一个不存在的虚拟机
from ssh.ssh import SSHClient
if __name__ == '__main__':
ssh = SSHClient(ip="192.168.1.2", port=22, username="root", password="Mugen_runner@123456")
rs=ssh.wait_for_sshable(60)
print(rs)
ssh = SSHClient(ip="192.168.1.254", port=22, username="root", password="Mugen_runner@123456")
rs = ssh.wait_for_sshable(60)
print(rs)
执行结果为:
True
False
exec 用于执行命令
- 执行一条简单的命令,并获取执行命令的返回码、标准输出和标准错误 远程执行一条简单的命令,比如 ls,调试时需要将ip地址和用户名密码修改为自己的调试环境的信息
from ssh.ssh import SSHClient
if __name__ == '__main__':
ssh = SSHClient(ip="192.168.1.2", port=22, username="root", password="xxxx")
rs = ssh.exec("ls /")
print(f"exit_status_code:{rs.exit_status_code}")
print(f"stdout:{rs.stdout}")
print(f"stderr:{rs.stderr}")
执行结果如下:
exit_status_code:0
stdout:afs
