Tomcat下使用Log4j 接管 catalina.out 日志文件生成方式,按天存放,解决catalina.out日志文件过大问题
1. 准备jar包:
log4j-1.2.17.jar (从 下载)
tomcat-juli.jar, tomcat-juli-adapters.jar (从 下载,根据你的Tomcat版本选择对应的分支)
2. 将上面的三个jar包拷贝到 Tomcat 的 lib 目录下;
3. 将 tomcat-juli.jar 拷贝到 Tomcat 的 bin 目录下,替换原有的jar包;
4. 修改 Tomcat 的 conf/context.xml 文件,将为
(增加 swallowOutput="true" 的属性配置,只有这样才能完全的把tomcat的stdout给接管过来。这一步很关键 在官网及网上找了许多资料都没有提及。);
5. 删除 Tomcat 的 conf/logging.properties 文件(或者重命名-建议);
6、在 Tomcat 的 lib 目录下创建 log4j.properties 文件:
-
log4j.rootLogger=INFO, CATALINA
-
-
# Define all the appenders
-
log4j.appender.CATALINA=org.apache.log4j.DailyRollingFileAppender
-
log4j.appender.CATALINA.File=${catalina.base}/logs/catalina.
-
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.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

-
-
