分享一段php获取linux服务器状态的代码
简单的php获取linux服务器状态的代码，不多说-直接上函数：
functionget_used_status(){
$fp=popen('top-b-n2|grep-E"^(Cpu|Mem|Tasks)"',"r");//获取某一时刻系统cpu和内存使用情况
$rs="";
while(!feof($fp)){
$rs.=fread($fp,1024);
}
pclose($fp);
$sys_info=explode("\n",$rs);
$tast_info=explode(",",$sys_info[3]);//进程数组 $cpu_info=explode(",",$sys_info[4]); //CPU占有量 数组 $mem_info=explode(",",$sys_info[5]);//内存占有量数组
//正在运行的进程数 $tast_running=trim(trim($tast_info[1],'running')); //CPU占有量 $cpu_usage=trim(trim($cpu_info[0],'Cpu(s):'),'%us'); //百分比 //内存占有量 $mem_total=trim(trim($mem_info[0],'Mem:'),'ktotal'); $mem_used=trim($mem_info[1],'kused'); $mem_usage=round(100*intval($mem_used)/intval($mem_total),2); //百分比
/*硬盘使用率begin*/ $fp=popen('df-lh|grep-E"^(/)"',"r"); $rs=fread($fp,1024); pclose($fp); $rs=preg_replace("/\s{2,}/",'',$rs); //把多个空格换成“_” $hd=explode("",$rs); $hd_avail=trim($hd[3],'G');//磁盘可用空间大小单位G $hd_usage=trim($hd[4],'%');//挂载点百分比 //print_r($hd); /*硬盘使用率end*/ //检测时间 $fp=popen("date+\"%Y-%m-%d%H:%M\"","r"); $rs=fread($fp,1024); pclose($fp); $detection_time=trim($rs); /*获取IP地址 begin*/ /* $fp=popen('ifconfigeth0|grep-E"(inetaddr)"','r'); $rs=fread($fp,1024); pclose($fp); $rs=preg_replace("/\s{2,}/",'',trim($rs)); //把多个空格换成“_” $rs=explode("",$rs); $ip=trim($rs[1],'addr:'); */ /*获取IP地址end*/ /* $file_name="/tmp/data.txt";//绝对路径:homedata.dat $file_pointer=fopen($file_name,"a+");//"w"是一种模式，详见后面 fwrite($file_pointer,$ip);//先把文件剪切为0字节大小，然后写入 fclose($file_pointer);//结束 */ return array('cpu_usage'=>$cpu_usage,'mem_usage'=>$mem_usage,'hd_avail'=>$hd_avail,'hd_usage'=>$hd_usage,'tast_running'=>$tast_running,'detection_time'=>$detection_time); }
