几个启动和检测脚本 防止自己忘记

nginx 启动脚本：

     stop)
           stop

           usage
   esac
  else
   usage

cp nginxd /etc/init.d/nginx
chkconfig --add nginx
service nginx restart

memcached 脚本：

启动脚本：

#!/bin/bash
# author:kuangl
# date:2013-05-30
# description: Starts and stops the Memcached services.
# pidfile: /tmp/memcached1.pid
# config:  /usr/local/memcached
# chkconfig: - 55 45
# source function library
. /etc/rc.d/init.d/functions
memcached="/usr/local/memcached/bin/memcached"
[ -e $memcached ] || exit 1
start()
{
echo "Starting memcached:"
daemon $memcached -d -m 2048 -u root -l 127.0.0.1 -p 11211 -c 10240 -P /tmp/memcached1.pid
}
stop()
{
echo "Shutting down memcached"
killproc memcached
}
case "$1" in
start)
start
;;
stop)
stop
;;
restart)
stop
sleep 3
start
;;
*)
echo $"Usage: $0 {start|stop|restart}"
exit 1
esac
exit $?

memcached 检测脚本：

这个脚本要配合crontab 来使用

#!/bin/bash
#Func:test memcached dead  reboot memcached
#date:2014/03/27
#BY:renzhenxing
#version:v0.1
mem=`ps -ef | grep mem | grep "mem" | egrep -v "vmmemctl|grep"| wc -l`
if [ $mem -eq 1 ];then
 echo  "mem is ok!!!"
 exit 0
else
 echo  "mem is dead !"
 /usr/local/memcached/bin/memcached -d -m 2048 -u root -l 127.0.0.1 -p 11211 -c 10240 -P /tmp/memcached1.pid
fi
