[ Python ] paramiko를 이용한 pem-key SSH 접속 (자동화 작업)

 

key 인증을 이용하여 접속시 parakimo 사용

 

import paramiko

key = paramiko.RSAKey.from_private_key_file("pemfilepath")
conn = paramiko.SSHClient()
conn.set_missing_host_key_policy(paramiko.AutoAddPolicy())
conn.connect(hostname = " ", username = "", pkey = key )

stdin, stdout, stderr = conn.exec_command('echo "hello"')
stdin.close()

for line in stdout.read().splitlines():
    print(line.decode())
                
conn.close()

--------------------------------------------------------------

hello

 

 

 

 

예제로 yum을 이용하여 zabbix-agent를 업데이트 해본다.

 

stdin, stdout, stderr = conn.exec_command('sudo yum update zabbix-agent.x86_64 -y')
stdin.close()

for line in stdout.read().splitlines():
    print(line.decode())

정상적으로 업데이트가 되었다.

 

 

 

 

다수의 ec2에 일괄작업을 위해서 아래와 같이 접속정보를 딕셔너리로 저장한 후 loop를 활용하면 될 것이다.

 

ec2s = {'host':'keyfile'}
