resin和tomcat 日志配置

我是靠谱客的博主冷艳小丸子，这篇文章主要介绍resin和tomcat 日志配置，现在分享给大家，希望可以做个参考。

1、tomcat发布项目日志

今天用tomcat发布其他离职同事写的IndexBysolr项目，发现始终转向error.jsp页面，还以为是找不到请求路径错误或者别filter拦截了！！！！！！项目中配置了debug、info、error日志，从这些日志以及tomcat的catalina.out中没有发现任何有效信息。 tomcat中 stdout log and stderr log日志不打印到任何地方（windows下）！！！

------404、500等都转向error.jsp。问其他同事说不会把有效信息返回给用户，所以所有异常都返回了error.jsp文件，这也是我之前不知道的地方！！！！！

2、resin发布项目日志

后来改为resin-4.0发布（起初也没有配置sdout、sderror日志），resin控制台输出了有效信息（action处理中 No live solrServer 信息），这个信息就是stout和sterror信息，tomcat控制台则神马都没有输出。

resin中 stdout log and stderr log 默认打印到控制台dos窗口（windows下）；

resin中 stdout log and stderr log配置输出到文件，resin4.0.0中日志配置（resin.xml）：

Resin中对日志的设置主要有如下参数：log、logger、access-log、stdout-log和stderr-log。前两个放在<resin>标签，也就是主标签下面，其中log主要用于配置JDK logging API，logger用于指定需要log的包及level，跟log4j中的用法相似，只不过resin中level有个特殊的选项就是off，用于关闭日志输出；而后面三个*-log放在<host>或<host-default>下面，access用于HTTP输出，stdout用于标准输出(System.out)，stderr用于错误输出(System.err，对应log4j中的log.error)。

三个*-log中间的属性是相同的，所以我们集中来说明一下：

path: 用于设定日志文件的路径，非常有意思的是它支持所谓的El Variables and Functions，也就是resin中的变量，比如${host.name}就是虚拟站点的id名称，所以如果将它放在<host-default>下面的话，将path设置为 logs/${host.name}/access.log的话可以将不同站点的日志存放在不同的目录下面。
archive-format: 这个参数可以设置日志归档的格式，如设置为access-%Y%m%d.log可以在归档的时候自动按日期进行归档命名。另外还有一个特性需要说明的是，resin竟然支持自动压缩log文件，而且设置的方法非常简单，只要后缀名是gz就可以了，如access-%Y%m%d.log.gz，这样归档的时候会自动压缩，而且支持windows和linux系统。
format: 用于设置每条日志输出的格式，这个非常简单，而且通常使用系统内置的格式就可以了。
rollover-size: 用来设置归档日志文件的最小尺寸，单位可以设置成kb、mb等等，默认为1mb。
rollover-period: 用来设置归档日志文件的周期，单位可以是1D（一天）、1W(一周)、1M（一个月）等。

最后给出一个范例供大家参考：

<!--
- Resin 3.1 configuration file.
-->
<resin xmlns="http://caucho.com/ns/resin"
xmlns:resin="http://caucho.com/ns/resin/core">
<!--
- Logging configuration for the JDK logging API.
-->
<log name="" level="off" path="stdout:"
timestamp="[%H:%M:%S.%s] {%{thread}} "/>
<!--
- 'info' for production
- 'fine' or 'finer' for development and troubleshooting
-->
<logger name="com.caucho" level="info"/>
<logger name="com.caucho.java" level="config"/>
<logger name="com.caucho.loader" level="config"/>
<host-default>
<!--
- With another web server, like Apache, this can be commented out
- because the web server will log this information.
-->
<access-log path="logs/${host.name}/access.log"
archive-format="access-%Y%m%d.log.gz"
format='%h %l %u %t "%r" %s %b "%{Referer}i" "%{User-Agent}i"'
rollover-size="10mb"
rollover-period="1D"/>
<!--
- stdout log and stderr log
-->
<stdout-log path="logs/${host.name}/stdout.log"
archive-format="stdout-%Y%m%d.log.gz"
timestamp="[%Y.%m.%d %H:%M:%S.%s]"
rollover-size="10mb"
rollover-period="1D"/>
<stderr-log path="logs/${host.name}/stderr.log"
archive-format="stderr-%Y%m%d.log.gz"
timestamp="[%Y.%m.%d %H:%M:%S.%s]"
rollover-size="10mb"
rollover-period="1D"/>
</host-default>
</resin>

最后还有一个事情需要说明一下，如果在windows系统下将resin注册成服务程序之后就会在log目录下产生jvm-defautl.log文件，而且这个文件会一直累加，所以会变的文件非常大而影响resin的性能。原来在Apache和Resin产生大容量日志的解决办法这篇文件中提到的使用httpd -jvm-log NUL的方法在3.1中无法使用，而且查找了大量的文档也没有找到合适的方法，后来索性将log目录中的写入权限去掉了，重启resin也没有任何影响，算是解决了这个问题。
