在開發/測試環境，日志是非常重要的。而公司對于測試環境進行了控制，只有配置人員能連接訪問，而開發人員是無法獲取該服務器的信息的。在出現錯誤時，沒有異常日志，開發是很難重現問題的。因此需要對中間件 tomcat 進行配置，將日志放到某個目錄下，開發人員可以通過瀏覽器就能查看日志。ok，開工：
目的 ： 能通過瀏覽器檢查tomcat日志
方法 ：將 tomcat 的日志放置到 $CATALINA_HOME/webapps/ROOT/logs 下，用戶就可以通過 http://xxx.xxx.xxx.xxx/logs/catalina.out 訪問日志了。
1. 修改tomcat/conf下的logging.properties?

2. 修改tomcat/bin/catalina.sh?
?
186 if [ -z "$CATALINA_OUT" ] ; then
187 CATALINA_OUT=
"$CATALINA_BASE"/webapps/ROOT/logs/catalina.out
188 fi
【注意】紅色字體是需要修改的內容，修改為當前 tomcat 的最新的網站根目錄即可。
?
3、重啟 tomcat
4、使用瀏覽器即可查看日志：?http://xxx.xxx.xxx.xxxx/logs/catalina.out
?
