Start and monitor of SH memcached process

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"

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
