如下,以创建系统用户举例,
配置文件配置普通用户信息,登入后切换root用户,创建一个指定名字和密码的系统用户:
def create_user(root_pwd,username,password): import paramiko result = [] ssh = paramiko.SSHClient() #把要连接的机器添加到known_hosts文件中 ssh.load_system_host_keys() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect( hostname = settings.HOST, port = settings.PORT, username = settings.USERNAME, password = settings.PASSWORD, timeout = 60, ) sc = ssh.invoke_shell() def exe_cmd(cmd,t=0.1): sc.send(cmd) sc.send("\n") time.sleep(t) resp = sc.recv(9999).decode("utf8") #print "cmd='%s',echo='%s'\n"%(cmd,resp) return resp #切换root账号 resp = exe_cmd("su root",t=1) if resp.endswith(u"密码:"): resp = exe_cmd(root_pwd) #创建用户 cmd_create_user = "useradd {username} -d /home/{username}".format( username = username, ) exe_cmd(cmd_create_user) #修改密码 cmd_change_user_pwd = """echo "{password}" | passwd --stdin {username}""".format( username = username, password = password, ) exe_cmd(cmd_change_user_pwd)
以上这篇python 切换root 执行命令的方法就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持。
