一、首先是準備jar包
需要log4j-1.2.17.jar，tomcat-juli.jar，tomcat-juli-adapters.jar。tomcat-juli.jar，tomcat-juli-adapters.jar需要根據tomcat版本進行下載。
以tomcat8.0.52為例，https://tomcat.apache.org/download-80.cgi
全部版本的tomact在連結 https://archive.apache.org/dist/tomcat/ 都可以找到
找到對應的版本，可以在bin/extras目錄下找到
二、操作步驟
1.將準備好的log4j-1.2.17.jar、tomcat-juli-adapters.jar上傳到 Tomcat lib目錄下
2.Tomcat bin目錄下的tomcat-juli.jar重新命名(暫時不刪除 以備有問題恢復) 並上傳tomcat-juli.jar到bin目錄下
3.修改 Tomcat conf/context.xml 檔案，將<Context>為<Context swallowOutput="true">
4.重新命名Tomcat 的 conf/logging.properties 檔案（暫時不刪除 以備有問題恢復）
5.在 Tomcat 的 lib 目錄下建立 log4j.properties 檔案
log4j.rootLogger=INFO, CATALINA # Define all the appenders log4j.appender.CATALINA=org.apache.log4j.DailyRollingFileAppender log4j.appender.CATALINA.File=${catalina.base}/logs/catalina.out log4j.appender.CATALINA.Append=true log4j.appender.CATALINA.Encoding=UTF-8 # Roll-over the log once per day log4j.appender.CATALINA.DatePattern='.'yyyy-MM-dd'.log' log4j.appender.CATALINA.layout = org.apache.log4j.PatternLayout log4j.appender.CATALINA.layout.ConversionPattern = %d [%t] %-5p %c- %m%n log4j.appender.LOCALHOST=org.apache.log4j.DailyRollingFileAppender log4j.appender.LOCALHOST.File=${catalina.base}/logs/localhost log4j.appender.LOCALHOST.Append=true log4j.appender.LOCALHOST.Encoding=UTF-8 log4j.appender.LOCALHOST.DatePattern='.'yyyy-MM-dd'.log' log4j.appender.LOCALHOST.layout = org.apache.log4j.PatternLayout log4j.appender.LOCALHOST.layout.ConversionPattern = %d [%t] %-5p %c- %m%n log4j.appender.MANAGER=org.apache.log4j.DailyRollingFileAppender log4j.appender.MANAGER.File=${catalina.base}/logs/manager log4j.appender.MANAGER.Append=true log4j.appender.MANAGER.Encoding=UTF-8 log4j.appender.MANAGER.DatePattern='.'yyyy-MM-dd'.log' log4j.appender.MANAGER.layout = org.apache.log4j.PatternLayout log4j.appender.MANAGER.layout.ConversionPattern = %d [%t] %-5p %c- %m%n log4j.appender.HOST-MANAGER=org.apache.log4j.DailyRollingFileAppender log4j.appender.HOST-MANAGER.File=${catalina.base}/logs/host-manager log4j.appender.HOST-MANAGER.Append=true log4j.appender.HOST-MANAGER.Encoding=UTF-8 log4j.appender.HOST-MANAGER.DatePattern='.'yyyy-MM-dd'.log' log4j.appender.HOST-MANAGER.layout = org.apache.log4j.PatternLayout log4j.appender.HOST-MANAGER.layout.ConversionPattern = %d [%t] %-5p %c- %m%n log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender log4j.appender.CONSOLE.Encoding=UTF-8 log4j.appender.CONSOLE.layout = org.apache.log4j.PatternLayout log4j.appender.CONSOLE.layout.ConversionPattern = %d [%t] %-5p %c- %m%n # Configure which loggers log to which appenders log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost]=INFO, LOCALHOST log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/manager]=\ INFO, MANAGER log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/host-manager]=\ INFO, HOST-MANAGER
6.重啟Tomcat
