使用paramiko模块在远程服务器执行命令
脚本如下：
# cat myssh.py
#!/usr/bin/env python
import paramiko
hostname = '192.168.56.101'
port = 22
username = 'root'
password = '111111'
if __name__ == "__main__":
paramiko.util.log_to_file('paramiko.log')
s = paramiko.SSHClient()
s.load_system_host_keys()
s.connect(hostname, port, username, password)
stdin, stdout, stderr = s.exec_command('ifconfig')
print stdout.read()
s.close()
执行结果为：
# python myssh.py eth0 Link encap:Ethernet HWaddr 08:00:27:29:46:94 inet addr:192.168.56.101 Bcast:192.168.56.255 Mask:255.255.255.0 inet6 addr: fe80::a00:27ff:fe29:4694/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:602 errors:0 dropped:0 overruns:0 frame:0 TX packets:381 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:64585 (63.0 KiB) TX bytes:61809 (60.3 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:14 errors:0 dropped:0 overruns:0 frame:0 TX packets:14 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1294 (1.2 KiB) TX bytes:1294 (1.2 KiB)
#!/usr/bin/env python
# coding: utf-8
import paramiko
ssh = paramiko.SSHClient()
#
# automatic reply yes if the ~/.ssh/known_hosts has no
# your machine entry
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('192.168.56.102', 22, 'root', '111111')
stdin, stdout, stderr = ssh.exec_command('df -h')
print stdout.read()
ssh.close()
运行结果为：
