记录的时候没有发现江南白衣大侠的文章
读了以后才知道我错了
还是直接看这个文章

window 上面的看

在sorlaris 上面

修改catalina.sh
==============================================
CATALINA_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=1861"
export CATALINA_OPTS

这样可以远程调试，可以google一下如何使用Eclipse 远程调试

================================================
LANG=zh
export LANG
LC_ALL=zh_CN.GB18030
export LC_ALL

设置字符集，如果不设置，经常出现字符集的问题，尤其使用xml文件的时候
=================================================
JAVA_OPTS='-server -XmsM -XmxM -XX:+UseConcMarkSweepGC -XX:+PrintGCDetails -XX:+PrintGCTimeStamps'
export JAVA_OPTS

设置内存
这是我的一个日志

=================================================
tomcat service.xml 文件修改

<Connector port="8080" maxHttpHeaderSize="8192"
useBodyEncodingForURI="true" maxThreads="1000"
minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443"
acceptCount="100" compression="on" compressionMinSize="2048"
compressableMimeType="text/html,text/xml,text/javascript,text/css,text/plain"

=============================================
