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 runningn" else printf "starting memcachedn" $MEMCACHED sleep 2 PID=$( cat $MEMCACHED_PID_FILE) printf "memcached is started PID:$PIDn" printf "starting memcached daemonn" ${ROOT}/${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 ${DAEMON_PID} fi printf "memcached daemon is stoppedn" else printf "no memcached daemon runningn" fi sleep 1 if [ -f "$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 stoppedn" else printf "no memcached runningn" 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
#!/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 runningn" else printf "starting memcachedn" $MEMCACHED sleep 2 PID=$( cat $MEMCACHED_PID_FILE) printf "memcached is started PID:$PIDn" printf "starting memcached daemonn" ${ROOT}/${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 ${DAEMON_PID} fi printf "memcached daemon is stoppedn" else printf "no memcached daemon runningn" fi sleep 1 if [ -f "$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 stoppedn" else printf "no memcached runningn" 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 restartedn" >> $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#]nn" 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__ ).

" ," . $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 . "rn" ); } } // class end ?>
在终端crontab执行
