一例实用的shell脚本,功能为:记录apache status状态信息,并且自动更新到数据库中
1,获取apache status,monitor_log.sh
复制代码代码示例:
#!/bin/bash
#连接数 site_connects=$(netstat -ant | grep $ip:80 | wc -l) #当前连接数 site_cur_connects=$(netstat -ant | grep $ip:80 | grep EST | wc -l) #apache apache_speed=$(netstat -n | awk '/^tcp/ {++S[$NF]} END {for(a in S) print a, S[a]}') printf "[#start#]\n$(date '+%Y-%m-%d %H:%M:%S')\n" printf "connects:${site_connects}\n" printf "cur connects:${site_cur_connects}\n" printf "apache_speed:\n${apache_speed}\n[#end#]\n\n" exit 0
设置任务计划,在终端设置crontab执行以上的shell脚本:
复制代码代码示例:
* * * * * /home/fdipzone/monitor_log.sh >> /home/fdipzone/monitor.log
2,将apache status log 写入数据库 save_monitor_log.php
复制代码代码示例:
<?php
$logfile = dirname(__FILE__).'/monitor.log'; $dbconfig = array( 'host' => '192.168.1.100', 'username' => 'username', 'password' => 'password', 'dbname' => 'mydb', 'tabname' => 'monitor_log' ); $obj = new SaveMonitorLog($dbconfig, 'myweb'); $obj->load($logfile); // 读取monitor log,记录入db,查看db class SaveMonitorLog{ // class start private $_apache_state = array('TIME_WAIT', 'CLOSE_WAIT', 'SYN_SENT', 'SYN_RECV', 'FIN_WAIT1', 'FIN_WAIT2', 'ESTABLISHED', 'LAST_ACK', 'CLOSING'); private $_dbconfig = array(); private $_site = null; /** init */ public function __construct($dbconfig=array(), $site='web'){ if(!isset($dbconfig['host']) || !isset($dbconfig['username']) || !isset($dbconfig['password']) || !isset($dbconfig['dbname']) || !isset($dbconfig['tabname'])){ $this->debug('dbconfig error'); } $this->_dbconfig = $dbconfig; $this->_site = $site; $this->connectdb(); } /** load data * @param String $logfile log文件 * @return boolean */ public function load($logfile){ // 读取log数据 if(file_exists($logfile)){ $logdata = file_get_contents($logfile); // 清空monitor.log file_put_contents($logfile, '', true); }else{ return false; } // 正則分析数据 [#start#]*[#end#] preg_match_all('/\[#start#\](.*?)\[#end#\].*?/si', $logdata, $data); if(isset($data[1]) && count($data[1])>0){ $alldata = $data[1]; foreach($alldata as $val){ $indb = $this->parser($val); $newid = $this->addtodb($indb); } } } /** parser data * @param Array $data * @return Array */ private function parser($data){ $indb = array(); $tmp = explode(chr(10), $data); // 按換行分隔 $indb['site'] = $this->_site; $indb['addtime'] = $tmp[1]; $indb['connects'] = array_pop(explode(':',$tmp[2])); $indb['cur_connects'] = array_pop(explode(':',$tmp[3])); for($i=5, $max=count($tmp)-2; $i<$max; $i++){ list($key, $num) = explode(' ', $tmp[$i]); if(in_array($key, $this->_apache_state)){ $indb[$key] = $num; } } return $indb; } /** connect db */ private function connectdb(){ $conn=@mysql_connect($this->_dbconfig['host'], $this->_dbconfig['username'], $this->_dbconfig['password']) or die(mysql_error()); mysql_select_db($this->_dbconfig['dbname'], $conn) or die(mysql_error()); } /** add to db */ private function addtodb($indb){ $insertkey = ''; $insertval = ''; if($indb){ foreach($indb as $key=>$val){ $insertkey .= $insertkey? " ,".$key : $key; $insertval .= $insertval? " ,'".mysql_escape_string(trim($val))."'" : "'".mysql_escape_string(trim($val))."'"; } $sqlstr = "insert into ".$this->_dbconfig['tabname']."($insertkey) values($insertval)"; $query = @mysql_query($sqlstr) or die(mysql_error()); $id = mysql_insert_id(); return $id? $id : false; } } /** debug */ private function debug($msg){ exit($msg."\r\n"); } } // class end ?>
设置计划任务,在终端crontab执行:
复制代码代码示例:
0 0 * * * php /home/fdipzone/save_monitor_log.php
3,表table:monitor_log struct
复制代码代码示例:
CREATE TABLE IF NOT EXISTS `monitor_log` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT, `site` varchar(20) NOT NULL, `connects` int(10) unsigned NOT NULL DEFAULT '0', `cur_connects` int(10) unsigned NOT NULL DEFAULT '0', `TIME_WAIT` int(10) unsigned NOT NULL DEFAULT '0', `CLOSE_WAIT` int(10) unsigned NOT NULL DEFAULT '0', `SYN_SENT` int(10) unsigned NOT NULL DEFAULT '0', `SYN_RECV` int(10) unsigned NOT NULL DEFAULT '0', `FIN_WAIT1` int(10) unsigned NOT NULL DEFAULT '0', `FIN_WAIT2` int(10) unsigned NOT NULL DEFAULT '0', `ESTABLISHED` int(10) unsigned NOT NULL DEFAULT '0', `LAST_ACK` int(10) unsigned NOT NULL DEFAULT '0', `CLOSING` int(10) unsigned NOT NULL DEFAULT '0', `addtime` datetime NOT NULL, PRIMARY KEY (`id`), KEY `connects` (`connects`), KEY `cur_connects` (`cur_connects`), KEY `TIME_WAIT` (`TIME_WAIT`), KEY `CLOSE_WAIT` (`CLOSE_WAIT`), KEY `SYN_SENT` (`SYN_SENT`), KEY `SYN_RECV` (`SYN_RECV`), KEY `FIN_WAIT1` (`FIN_WAIT1`), KEY `FIN_WAIT2` (`FIN_WAIT2`), KEY `ESTABLISHED` (`ESTABLISHED`), KEY `LAST_ACK` (`LAST_ACK`), KEY `CLOSING` (`CLOSING`), KEY `addtime` (`addtime`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 ; (责任编辑:IT) |
