我就废话不多说了，直接上代码吧！

import paramikoimport pymysqlimport timelinux = ['192.168.0.179']def connectHost(ip, uname='shenyuming', passwd='ajiongqqq'):  ssh = paramiko.SSHClient()  ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())  ssh.connect(ip, username=uname, password=passwd,port=22)  return sshdef MainCheck():  try:    while True:      time.sleep(1)      for a in range(len(linux)):        ssh = connectHost(linux[a])        # 查询主机名称        cmd = 'hostname'        stdin, stdout, stderr = ssh.exec_command(cmd)        host_name = stdout.readlines()        host_name = host_name[0]        # 查看当前时间        csj = 'date +%T'        stdin, stdout, stderr = ssh.exec_command(csj)        curr_time = stdout.readlines()        curr_time = curr_time[0]    # 查看cpu使用率，并将信息写入到数据库中(取三次平均值)        cpu = "vmstat 1 3|sed '1d'|sed '1d'|awk '{print $15}'"        stdin, stdout, stderr = ssh.exec_command(cpu)        cpu = stdout.readlines()        cpu_usage = str(round((100 - (int(cpu[0]) + int(cpu[1]) + int(cpu[2])) / 3), 2)) + '%'        # 查看内存使用率，并将信息写入到数据库中        mem = "cat /proc/meminfo|sed -n '1,4p'|awk '{print $2}'"        stdin, stdout, stderr = ssh.exec_command(mem)        mem = stdout.readlines()        mem_total = round(int(mem[0]) / 1024)        mem_total_free = round(int(mem[1]) / 1024) + round(int(mem[2]) / 1024) + round(int(mem[3]) / 1024)        mem_usage = str(round(((mem_total - mem_total_free) / mem_total) * 100, 2)) + "%"        sql = "insert into memory_and_cpu values('%s','%s','%s','%s')" % (        host_name, curr_time, cpu_usage, mem_usage)        db = connectDB()        sqlDML(sql, db)  except:    print("连接服务器 %s 异常" % (linux[a]))def connectDB(dbname='test11'):  if dbname == 'test11':    db = pymysql.connect("localhost", "root", "shen123", "test11")    return dbdef sqlDML(sql, db):  cr = db.cursor()  cr.execute(sql)  db.commit()  cr.close()  #if __name__ == '__main__':  MainCheck()
