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" else printf "starting memcached" $MEMCACHED sleep 2 PID=$(cat $MEMCACHED_PID_FILE) printf "memcached is started PID:$PID" printf "starting memcached daemon" ${ROOT}/${MEMCACHED_DAEMON_FILE} & DAEMON_PID=$! echo ${DAEMON_PID} > ${MEMCACHED_DAEMON_PID_FILE} printf "memcached daemon is started PID:${DAEMON_PID}" 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 ${DAEMON_PID} fi printf "memcached daemon is stopped" else printf "no memcached daemon running" fi sleep 1 if [ -f "$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" else printf "no memcached running" fi } case "$1" in start) start ;; stop) stop ;; restart) stop sleep 3 start ;; *) printf "Usage:$0 {start|stop|restart}" exit 1 esac exit 0 3.memcached_daemon.sh监控memcached 进程，如进程失效则自动启动。
#!/bin/sh #memcached daemon ROOT=$(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" >> $ERROR_LOG_FILE echo "Subject: ${SITE} ${HOST} memcached ${PORT} is restarted $(date +%Y-%m-%d" "%H:%M:%S)" | sendmail me@gmail.com fi sleep 5 done exit 0 使用方法：
./gm_memcached.sh start #启动memcached ./gm_memcached.sh stop #停止memcached ./gm_memcached.sh restart #重启memcached
shell 记录apache status并自动更新到数据库1. 获取apache statusmonitor_log.sh
#!/bin/bash #连接数 site_connects=$(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[$NF]} END {for(a in S) print a, S[a]}") printf "[#start#]$(date "+%Y-%m-%d %H:%M:%S")" printf "connects:${site_connects}" printf "cur connects:${site_cur_connects}" printf "apache_speed:${apache_speed}[#end#]" exit 0 在终端设置crontab执行
