判断当前tomcat状态并启动 shell

2012/11/13 | shell | Zhiming Zhang | 暂无评论 | 1515 views

好吧，今天写一个小shell，高难度的暂时还搞不定

#!/bin/bash
#检测tomcat状态并做相应的操作，启动tomcat
# maple 20121113

TOMCATPATH=/program/tomcat7-3/
#tomcat 路径
TOMCATPORT=8083
#tomcat 端口
cd $TOMCATPATH
pIDa=`/usr/sbin/lsof -i :$TOMCATPORT|grep -v "PID" | awk '{print $2}'`
if [ "$pIDa" != "" ];
#判断该端口是否被占用
then
#如果被占用
/usr/sbin/lsof -i :$TOMCATPORT|grep -v "PID"|awk '{print "kill -9",$2}'|sh&amp;&amp;bin/startup.sh
#杀掉端口并重启
else
#如果不被占用
bin/startup.sh
#直接重启
fi
tail -f logs/catalina.out
#显示启动日志

已经测试过了，可以用，没有清除日志…. 今天最大的收获就是知道了怎么去判断一个命令是否有输出…. 时间：2012-11-13 23:45:22

只有两句话： 1. 截断日志 BACKUP LOG [DatabaseName] WITH TRUNCATE_ONLY 2. 收缩数据库 DBCC SHRINKDATABASE ([DatabaseName], 10) SQLserver，效果显著。时间：2012-11-13 23:25:14

SHELL脚本判断某端口是否被占用

脚本刚写好，中午就不开虚拟机测试了，晚上到家一道测试

#!/bin/bash
#检查8080端口是否被占用，如果占用输出1，如果没有被占用输入0
pIDa=`/usr/sbin/lsof -i :8081|grep -v "PID" | awk '{print $2}'`
echo $pIDa
if [ "$pIDa" != "" ];
then
   echo "1"
else
   echo "0"
fi

现在很多网站是中英文分开的，用文件夹一个是/zh-cn 和/en-us 这个时候我们在与zh-cn 和 en-us 放一个jsp页面页面中放入如下代码：

&lt;script type="text/javascript"&gt;
function GetCookie(sName)
{
  var aCookie = document.cookie.split("; ");
  for (var i=0; i &lt; aCookie.length; i++)
  {
    var aCrumb = aCookie[i].split("=");
    if (sName == aCrumb[0]) 
      return unescape(aCrumb[1]);
  }
  return 0;
}
var cookieId=GetCookie("zone");
if(cookieId!="t"){
	&lt;%
	String lang = request.getHeader("Accept-Language");
	if(lang!=null&amp;&amp;lang.length()&gt;2){
		lang = lang.substring(0,2);
	}
	if(lang!=null&amp;&amp;lang.equals("en")){
	%&gt;
		window.location.href="http://www.abc.com/en-us/";
	&lt;%
	}else if(lang!=null&amp;&amp;lang.equals("fr")){

	}else if(lang!=null&amp;&amp;lang.equals("ar")){
