PHP + shell script for Memcached and Apache Status instances, memcachedapache

Memcached process initiation and monitoring
1. memcached_inc.sh
Set the path, port, and other information.

#!/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
Control memcached startup, stop, and restart.

#!/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
Monitor memcached processes. If the process fails, it is automatically started.

#!/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 

Usage:

./Gm_memcached.sh start # start memcached./gm_memcached.sh stop # stop memcached./gm_memcached.sh restart # restart memcached

The shell records apache status and automatically updates it to the database.
1. Obtain apache status
Monitor_log.sh

#! /Bin/bash # Number of connections site_connects =$ (netstat-ant | grep $ ip: 80 | wc-l) # current number of connections 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, 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 "exit 0

Set crontab on the terminal for execution

2. Write apache status log to the database
Save_monitor_log.php

<? Php $ logfile = dirname (_ FILE __).
