Php+shell script Operations memcached and Apache status instance sharing, Memcachedapache

memcached process Start-up and monitoring
1.memcached_inc.sh
Set the path, port and other messages.

#!/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 "  

2.gm_memcached.sh
Control memcached Start, stop, restart.

#!/bin/sh #memcached start and stop #$1 action root=$ (CD "$ (dirname") "; pwd"). ${root}/memcached_inc.sh Start () {if [-f] $MEMCACHED _pid_file "] && [-S" $MEMCACHED _pid_file "]; then PRI ntf "Memcached already running\n" Else printf "starting memcached\n" $MEMCACHED sleep 2 pid=$ (cat $MEMCACHED _pi D_file) printf "memcached is started PID: $PID \ n" printf "starting memcached daemon\n" ${root}/${memcached_daemon_fi   LE} & daemon_pid=$! Echo ${daemon_pid} > ${memcached_daemon_pid_file} printf "MEMCACHED DAEMON is started pid:${daemon_pid}\n" fi} s Top () {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 ${pid} fi printf "memcached was stopped\n" else printf "no memcached running\n" fi} case "$" I   n 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
Monitor the memcached process, such as process failure, and start automatically.

#!/bin/sh  #memcached Daemon  root=$ (cd "$ (dirname") "; 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 $} ' | 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  

How to use:

Shell records Apache status and updates to database automatically
1. Get Apache Status
monitor_log.sh

#!/bin/bash  #连接数 site_connects=$ (netstat-ant | grep $ip: | wc-l) #当前连接数 site_cur_connects=$ (netstat-ant | grep $i p:80 | grep EST | wc-l)  #apache apache_speed=$ (netstat-n | awk '/^tcp/{++s[$NF]} END {for (A-in S) print A, S[a]} ')  printf "[#star t#]\n$ (date ' +%y-%m-%d%h:%m:%s ') \ nthe "printf" connects:${site_connects}\n "printf" cur connects:${site_cur_connects}\n "printf" apache_speed:\n${apache_speed}\n[#end #]\n\n "  

Crontab execution in Terminal setup

2. Write Apache status log to the database
save_monitor_log.php

<?php $logfile = dirname (__file__). '  /monitor.log '; $dbconfig = Array (' host ' = ' 192.168.1.100 ', ' username ' = ' username ', ' password ' = ' password ', ' db '  Name ' = ' mydb ', ' tabname ' = ' monitor_log '); $obj = new Savemonitorlog ($dbconfig, ' myweb ');   $obj->load ($logfile); Read monitor log, record in db, view 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 ($dbconf ig[' username ') | | !isset ($dbconfig [' Password ']) | | !isset ($dbconfig [' dbname ']) | |   !isset ($dbconfig [' tabname ']) {$this->debug (' dbconfig error ');   } $this->_dbconfig = $dbconfig;   $this->_site = $site;  $this->connectdb (); /** Load Data * @param String $logfile log file * @return Boolean */Public Function load ($logfile) {//read log according to if (File_exists ($logfile)) {$logdata = File_get_co    Ntents ($logfile);   Empty Monitor.log file_put_contents ($logfile, ", true);   }else{return false; }//The analysis of the numbers [#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), $data);   separated by line $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->_dbcon   fig[' 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?
