Python第三方库paramikois for remote controllinux主机的,进行ssh连接时,需要用到Python的paramiko,Dependent libraries must be installed first
安装命令:
pip install paramiko
导入包:
import paramiko
连接方法:
paramiko.SSHClient()
执行方法:
exec_command()
断开连接:
close()
代码如下(示例):
import paramiko
class SSHLinux():
def __init__(self, hostname, port, username, password):
# 创建sshClient实例对象
ssh = paramiko.SSHClient()
# Set to trust the remote machine,允许访问
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
self.ssh = ssh
self.ssh.connect(hostname,port=port,username=username, password=password)
def use_command(self,cmd):
try:
""" stdin 标准格式的输入,是一个写权限的文件对象 stdout 标准格式的输出,是一个读权限的文件对象 stderr 标准格式的错误,是一个写权限的文件对象” Executing the command returns three objects,调用一次exec_commandThe method is equivalent to reopening it oncelinux终端 """
stdin,stdout,stderr = self.ssh.exec_command(cmd)
res = stdout.read().decode()
return res
except Exception as e:
print(e)
finally:
self.ssh.close()
hostname = "192.168.90.X"
port = 22
username = "root"
password = ""
ssh = SSHLinux()(hostname, port=port, username=username, password=password)
ssh.use_command("ll")
