1.依赖包安装（ssh协议工具包）
pip install paramiko
2.主机配置
host = {‘ip‘: ip, ‘port‘: port, ‘username‘: username, ‘password‘: password}
3.远程执行命令并获取返回结果
#打开ssh客户端
ssh = paramiko.SSHClient()
# 设置为接受不在known_hosts 列表的主机可以进行ssh连接
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(hostname=host[‘ip‘], port=host[‘port‘], username=host[‘username‘], password=host[‘password‘])
#获取内存信息
stdin, stdout, stderr = ssh.exec_command(‘sudo free -m|grep Mem‘)
str_out = stdout.read().decode()
totalmem = str(str_out).split(" ")[1].replace(" ","")
freemem = str(str_out).split(" ")[2].replace(" ","")
ram_usage = str(int(freemem)/int(totalmem)*100).split(".")[0]+"%"
#获取cpu信息
stdin, stdout, stderr = ssh.exec_command(‘top -bn 1 -i -c|grep us|grep id‘)
str_out = str(stdout.read().decode()).replace(" ","")
cpu_usage = str(100-int(str_out.split(",")[3].split(".")[0]))+"%"
#获取磁盘信息
stdin, stdout, stderr = ssh.exec_command(‘df -h|grep G |grep -o [0-9]*%|grep [0-9][0-9]‘)
str_out = stdout.read().decode()
rom_usage = str(str_out).replace("\n","")
#关闭ssh客户端
ssh.close()
4.封装并返回环境信息
env_info={‘host‘:host[‘ip‘],‘ramusage‘:ram_usage,‘cpuusage‘:cpu_usage,‘romusage‘:rom_usage}
return env_info
5.前端动态请求回显
$(function () {
function getenvinfo(ip){
if (ip.length>8){
$.ajax({
type:‘GET‘,
url:‘http://localhost:8000/getEnvinfo‘,
data:{
ip:ip
},
success:function (result) {
console.log(result)
$(‘#cpuusage‘).find("span")[0].textContent=result.cpuusage
$(‘#cpuusage‘).attr("style","width: "+result.cpuusage)
$(‘#romusage‘).find("span")[0].textContent=result.romusage
$(‘#romusage‘).attr("style","width: "+result.romusage)
$(‘#ramusage‘).find("span")[0].textContent=result.ramusage
$(‘#ramusage‘).attr("style","width: "+result.ramusage)
},
error:function (e) {
console.log(e.status);
}
});
}
}
$(‘#ip‘).on(‘blur‘,function (){
getenvinfo($(this).val())
});
$(‘#ip‘).keyup(function(event){
if(event.keyCode ==13){
getenvinfo($(this).val())
}
});
setInterval(function (){
getenvinfo($(‘#ip‘).val())
},90000)
});
基于Django框架搭建
