分享Memcached shell啟動停止指令碼，memcachedshell

 注意：要使用這個shell，必須先成功建立memcache環境1》建立memcached檔案和許可權[root@luozhonghua ~]# touch /etc/init.d/memcached[root@luozhonghua ~]# chmod +x /etc/init.d/memcached2》編寫Memcached shell管理指令碼  vi  /etc/init.d/memcached#!/bin/bash# memcached  - This shell script takes care of starting and stopping memcached.## chkconfig: - 90 10# description: Memcache provides fast memory based storage.# processname: memcachedmemcached_path="/usr/local/bin/memcached"memcached_pid="/var/run/memcached.pid"memcached_memory="1024"# Source function library.. /etc/rc.d/init.d/functions[ -x $memcached_path ] || exit 0RETVAL=0prog="memcached"# Start daemons.start() {    if [ -e $memcached_pid -a ! -z $memcached_pid ];then        echo $prog" already running...."        exit 1    fi    echo -n $"Starting $prog "    # Single instance for all caches    $memcached_path -m $memcached_memory -l 0.0.0.0 -p 11211 -u root -d -P $memcached_pid    RETVAL=$?

4》測試（試試手啊）

<p>service memcached start|stop|status|restart </p>

shell指令碼啟動與停止apache 檢查apache的運行狀態 如果apache啟動了就讓它停止 ，如果停止了就啟動apach

ps -fe |grep "/usr/sbin/httpd"
if [ $? -eq 1 ]
then
service httpd restart
else
service httpd stop
fi
前面的grep裡面的內容根據原生情況進行修改
 
想寫一個在linux環境下用shell指令碼控制jar的啟動與停止，類似於一個後台服務那種的

一下是啟動指令碼

#該指令碼的使用方式為-->[sh startup.sh]
#該指令碼可在伺服器上的任意目錄下執行,不會影響到日誌的輸出位置等
