Tomcat 安装webalizer
Tomcat 安装webalizer（可以统计tomcat web的访问情况）安装tomcat 略（以tomcat 6为例，7基本相同）
# apt-get install webalizer
修改tomcat log格式
# vi /var/lib/tomcat6/conf/server.conf（加上rotatable="false"，在该文件最后）
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
prefix="localhost_access_log" suffix=".txt" pattern="common"
resolveHosts="false" rotatable="false"/> （注意去掉prefix="localhost_access_log."最后的"."
）
默认为：
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
prefix="localhost_access_log." suffix=".txt" pattern="common"
resolveHosts="false" />
:wq
# service tomcat6 restart
# mv /var/www/weblizer/var/lib/tomcat6/webapps/usage
# vi /etc/webalizer/webalizer.conf
LogFile /var/log/tomcat6/localhost_access_log.txt
OutputDir /var/lib/tomcat6/webapps/usage
:wq
启动weblizer
# weblizer
