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"

sleep 2

printf "memcached is started PID:$PID\n"

printf "starting memcached daemon\n"

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
