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" $MEMCACHED sleep 2 PID=$(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:$0 {start|stop|restart}\n" exit 1 esac exit 0
3.memcached_daemon.sh
监控memcached 进程,如进程失效则自动启动。
#!/bin/sh #memcached daemon ROOT=$(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${apache_speed}\n[#end#]\n\n" exit 0
在终端设置crontab执行
* * * * * /home/fdipzone/monitor_log.sh /home/fdipzone/monitor.log
2. 将apache status log 写入数据库
save_monitor_log.php
<" ,".$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"\r\n"); } } // class end "htmlcode">0 0 * * * php /home/fdipzone/save_monitor_log.php
table monitor_log structCREATE TABLE IF NOT EXISTS `monitor_log` ( `id` int(10) unsigned NOT NULL AUTO_INCREMENT, `site` varchar(20) NOT NULL, `connects` int(10) unsigned NOT NULL DEFAULT '0', `cur_connects` int(10) unsigned NOT NULL DEFAULT '0', `TIME_WAIT` int(10) unsigned NOT NULL DEFAULT '0', `CLOSE_WAIT` int(10) unsigned NOT NULL DEFAULT '0', `SYN_SENT` int(10) unsigned NOT NULL DEFAULT '0', `SYN_RECV` int(10) unsigned NOT NULL DEFAULT '0', `FIN_WAIT1` int(10) unsigned NOT NULL DEFAULT '0', `FIN_WAIT2` int(10) unsigned NOT NULL DEFAULT '0', `ESTABLISHED` int(10) unsigned NOT NULL DEFAULT '0', `LAST_ACK` int(10) unsigned NOT NULL DEFAULT '0', `CLOSING` int(10) unsigned NOT NULL DEFAULT '0', `addtime` datetime NOT NULL, PRIMARY KEY (`id`), KEY `connects` (`connects`), KEY `cur_connects` (`cur_connects`), KEY `TIME_WAIT` (`TIME_WAIT`), KEY `CLOSE_WAIT` (`CLOSE_WAIT`), KEY `SYN_SENT` (`SYN_SENT`), KEY `SYN_RECV` (`SYN_RECV`), KEY `FIN_WAIT1` (`FIN_WAIT1`), KEY `FIN_WAIT2` (`FIN_WAIT2`), KEY `ESTABLISHED` (`ESTABLISHED`), KEY `LAST_ACK` (`LAST_ACK`), KEY `CLOSING` (`CLOSING`), KEY `addtime` (`addtime`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 ;

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!
昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
