如何在WINDOW下配置TOMCAT APR:
APR是什么呢,(Tomcat can use the Apache Portable Runtime to provide superior scalability, performance, and better integration with native server technologies. )
Windows下的安装配置与使用
1、先去 下载编译好的 tcnative-1.dll 文件
2、把tcnative-1.dll文件放在Tomcat的bin目录下
然后启动TOMCAT,如果看到以下信息:
2008-8-31 17:28:59 org.apache.coyote.http11.Http11AprProtocol start
信息: Starting Coyote HTTP/1.1 on http-8080
2008-8-31 17:28:59 org.apache.coyote.ajp.AjpAprProtocol start]则配置成功
然后你可以用APACHE的AB命令测试下效果.
ab -n 1000 -c 300
相关APR的参数配置可以参考以下文档:
如何查看TOMCAT的并发访问量:
我们进入TOMCAT服务管理页面(),可以看到下面这段文字
http-8080Max threads: 1000 Min spare
threads: 0 Max spare threads: 0 Current thread count: 303 Current thread
busy: 234 Keeped alive sockets count: 0
Max processing time: 23531 ms Processing time: 29287.717 s Request
count: 2980 Error count: 0 Bytes received: 0.00 MB Bytes sent: 12.61 MB
Current thread count: 303 这个参数则代表当前TOMCAT的并发访问量
这是我TOMCAT服务器的配置:
enableLookups="false" redirectPort="8443" acceptCount="100"
compression="on" compressionMinSize="2048"
compressableMimeType="text/html,text/xml,text/javascript,text/css,text/plain"
connectionTimeout="20000" disableUploadTimeout="true" sendfileSize="2048" />
将TOMCAT日志更改为LOG4J日志输出
把commons-logging.jar,log4j-1.2.13.jar的两个JAR拷贝到tomcat_home/common/lib下面.
然后在将log4j.properties拷贝到tomcat_home/common/classes下面
