memcached进程启动及监控1.memcached_inc.sh设置路径,端口等讯息。#!/bin/sh#configincludeHOST=$(hostname)

memcached 进程启动及监控 1.memcached_inc.sh 设置路径,端口等讯息。


#!/bin/sh 
 
#config include 
 
HOST=$(hostname) 
SITE="mysite" 
PORT=11211 
 
MEMCACHED_PID_FILE="/tmp/memcached.pid" 
MEMCACHED_DAEMON_PID_FILE="/tmp/memcached_daemon.pid" 
 
MEMCACHED="memcached -d -m 64 -p $PORT -u memcache -l 127.0.0.1 -P $MEMCACHED_PID_FILE" 
MEMCACHED_DAEMON_FILE="memcached_daemon.sh" 
 
ERROR_LOG_FILE="${ROOT}/memcached_${SITE}_${HOST}_${PORT}.log" 

2.gm_memcached.sh 控制memcached 启动,停止,重启。


#!/bin/sh 
 
#memcached start and stop 
#$1 action 
 
ROOT=$(cd "$(dirname "$0")"; pwd) 
 
. ${ROOT}/memcached_inc.sh 
 
 
start() { 
 
 if [ -f "$MEMCACHED_PID_FILE" ] && [ -s "$MEMCACHED_PID_FILE" ]; then 
 printf "memcached already running\n" 
 else 
 printf "starting memcached\n" 
 $MEMCACHED 
 
 sleep 2 
 
 PID=$(cat $MEMCACHED_PID_FILE) 
 printf "memcached is started PID:$PID\n" 
 
 printf "starting memcached daemon\n" 
 ${ROOT}/${MEMCACHED_DAEMON_FILE} & 
 DAEMON_PID=$! 
 echo ${DAEMON_PID} > ${MEMCACHED_DAEMON_PID_FILE} 
 printf "memcached daemon is started PID:${DAEMON_PID}\n" 
 fi 
 
} 
 
 
stop() { 
 
 if [ -f "$MEMCACHED_DAEMON_PID_FILE" ] && [ -s "$MEMCACHED_DAEMON_PID_FILE" ]; then 
 DAEMON_PID=$(cat $MEMCACHED_DAEMON_PID_FILE) 
 rm -f ${MEMCACHED_DAEMON_PID_FILE} 
 if [ ! -z ${DAEMON_PID} ]; then 
 kill -9 ${DAEMON_PID} 
 fi 
 printf "memcached daemon is stopped\n" 
 else 
 printf "no memcached daemon running\n" 
 fi 
 
 sleep 1 
 
 if [ -f "$MEMCACHED_PID_FILE" ] && [ -s "$MEMCACHED_PID_FILE" ]; then 
 PID=$(cat $MEMCACHED_PID_FILE) 
 rm -f ${MEMCACHED_PID_FILE} 
 if [ ! -z ${PID} ]; then 
 kill -9 ${PID} 
 fi 
 printf "memcached is stopped\n" 
 else 
 printf "no memcached running\n" 
 fi 
 
} 
 
 
case "$1" in 
 
 start) 
 start 
 ;; 
 
 stop) 
 stop 
 ;; 
 
 restart) 
 stop 
 sleep 3 
 start 
 ;; 
 
 *) 
 printf "Usage:$0 {start|stop|restart}\n" 
 exit 1 
 
esac 
 
exit 0 

3.memcached_daemon.sh 监控memcached 进程,如进程失效则自动启动。


#!/bin/sh 
 
#memcached daemon 
 
ROOT=$(cd "$(dirname "$0")"; pwd) 
 
. ${ROOT}/memcached_inc.sh 
 
 
while : 
do 
 if [ -f "$MEMCACHED_PID_FILE" ] && [ -s "$MEMCACHED_PID_FILE" ]; then 
 PID=$(cat $MEMCACHED_PID_FILE) 
 else 
 PID="" 
 fi 
 
 if [ -z "$PID" ] || [ -z $(ps aux|awk '{print $2}' | grep "^$PID$") ]; then 
 $MEMCACHED 
 sleep 1 
 printf "[$(date +%Y-%m-%d' '%H:%M:%S)] ${SITE} ${HOST} memcached ${PORT} is restarted\n" >> $ERROR_LOG_FILE 
 echo "Subject: ${SITE} ${HOST} memcached ${PORT} is restarted $(date +%Y-%m-%d' '%H:%M:%S)" | sendmail me@gmail.com 
 fi 
 
 sleep 5 
 
done 
 
exit 0 

使用方法:


./gm_memcached.sh start #启动memcached 
./gm_memcached.sh stop #停止memcached 
./gm_memcached.sh restart #重启memcached 

shell 记录apache status并自动更新到数据库 1. 获取apache status monitor_log.sh


#!/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 

在终端设置crontab执行


* * * * * /home/fdipzone/monitor_log.sh >> /home/fdipzone/monitor.log 

2. 将apache status log 写入数据库 save_monitor_log.php


<?php 
 
$logfile = dirname(__FILE__).'/monitor.log'; 
 
$dbconfig = array( 
 'host' => '192.168.1.100',

 'tabname' => 'monitor_log' 
); 
 
$obj = new SaveMonitorLog($dbconfig, 'myweb'); 
$obj->load($logfile); 
 
 
// 讀取monitor log,記錄入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');

 $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){ 
 
 // 讀取log數據 
 if(file_exists($logfile)){ 
 $logdata = file_get_contents($logfile); 
 // 清空monitor.log 
 file_put_contents($logfile, '', true); 
 }else{ 
 return false; 
 } 
 
 // 正則分析數據 [#start#]*[#end#] 
 preg_match_all('/

#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

 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 
 
?> 

在终端crontab执行
