Carried out using the python ssh linux server and execute the command

1, the installation module paramiko

　　　　pip install paramiko

　　　Ssh connection timeout may be modified, the windows path: the installation path Python \ Python36 \ Lib \ site-packages \ paramiko \ transport.py, modify self.banner_timeout = 60 (ssh timeout set to 60 seconds)

2, performed by using ssh python

Import paramiko, the getpass   # the getpass hidden code

    # command to be executed 
    sed_command = " Sed -i' S / 123 / ABC / G '/root/test/test.txt " 
    ls_command = " LS / the root / Test / " 

    # Note: when performing a plurality of commands in sequence, separated by semicolons between command 
    command = sed_command + " ; "+ Ls_command 

    # SSH remote connections

    ssh.connect (host_ip, host_port, user_name, password) 

    # execute commands and get the results 
    stdin, stdout, stderr = ssh.exec_command (the command)
