Php+shell script Operations memcached and Apache status instances share _php instances

memcached Process Initiation and monitoring
1.memcached_inc.sh
Sets the path, port, and other messages.

#!/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 
 
_file= "${root}/memcached_${site}_${host}_${port}.log" 

2.gm_memcached.sh
Control memcached start, stop, reboot.

#!/bin/sh #memcached start and stop #$1 action root=$ (CD "$ (dirname" $) "; 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" ${root}/${me 
  Mcached_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" $MEMCACHED _daemon_pid_file]; then daemon_p id=$ (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 Runni Ng\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 "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, such as failure of processes to start automatically.

#!/bin/sh 
 
#memcached Daemon 
 
root=$ (cd "$ (dirname" $) "pwd) 
 
. ${root}/memcached_inc.sh while 
 
 
: 
do 
 if [f "$MEMCACHED _pid_file"] && [S "$MEMCACHED _pid_file]; then 
  pid=$ (cat $MEMCACHED _pid_fi LE) 
 Else 
  pid= "" " 
 fi 
  
 If [-Z" $PID "] | | [-Z $ (ps Aux|awk ' {print $} ' | 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 
 
 5 done 
 
exit 0 

How to use:

./gm_memcached.sh start #启动memcached 
./gm_memcached.sh stop #停止memcached 
./gm_memcached.sh Restart # Restart memcached 

Shell records Apache status and automatically updates to database
1. Get Apache Status
monitor_log.sh

#!/bin/bash 
 
#连接数 
site_connects=$ (netstat-ant | grep $ip: | wc-l) 
#当前连接数 
site_cur_connects=$ ( 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]} ' 
 
"[# 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

2. Write Apache status log to the database
save_monitor_log.php
