Tomcat catalina.out logs are split by day using log4j

Since Tomcat Catalina.out logs are not automatically split,

First, the log partition needs to be wrapped in the vicinity

1. There are three jar packages in the package:

Log4j-1.2.16.jar

Tomcat-juli-adapters.jar

Tomcat-juli.jar

Note: If not TOMCAT7 version, please go to the official website to download the corresponding version of the Tomcat-juli.jar,tomcat-juli-adapters.jar class package,

Download Address: Http://www.apache.org/dist/tomcat in the corresponding version of the Bin/extras path

Second, modify the relevant configuration file

1, modify the ${catalina.home}/conf/context.xml

Modified: <context > For <context swallowoutput= "true" > The only way to complete the stdout of Tomcat to take over.

2. Copy Log4j-1.2.16.jar and Tomcat-juli-adapters.jar to Tomcat's Lib

3, copy Tomcat-juli.jar to ${catalina.home}/bin, in this directory will exist the file, overwrite can

4, establish log4j.properties, and put it into the/lib of Tomcat

The contents of the log4j.properties are as follows: Relevant parameters can be modified as needed

Log4j.rootlogger=info, CATALINA

# Define all the Appenders

Log4j.appender.catalina=org.apache.log4j.dailyrollingfileappender

Log4j.appender.catalina.file=/home/richmail/logs/tomcat/catalina.log

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

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=/home/richmail/logs/tomcat/localhost.log

Log4j.appender.localhost.append=true

Log4j.appender.localhost.encoding=utf-8

Log4j.appender.localhost.datepattern= '. ' Yyyy-mm-dd

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=/home/richmail/logs/tomcat/manager.log

Log4j.appender.manager.append=true

Log4j.appender.manager.encoding=utf-8

Log4j.appender.manager.datepattern= '. ' Yyyy-mm-dd

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=/home/richmail/logs/tomcat/host-manager.log

Log4j.appender.host-manager.append=true

Log4j.appender.host-manager.encoding=utf-8

Log4j.appender.host-manager.datepattern= '. ' Yyyy-mm-dd

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

5. Modify Bin/catalina.sh

A. Block or delete the following:

(1) If [-Z] $CATALINA _out "]; Then

catalina_out= $CATALINA _base/logs/catalina.out fi

(2) Touch "$CATALINA _out"

(3) >> "$CATALINA _out" 2>&1 "&" (two places)

B. Modifying Org.apache.catalina.startup.Bootstrap "$@" Start \ Content (two places)

Modified to: Org.apache.catalina.startup.Bootstrap "$@" Start & \

6. Modify the Localhost_access_log log path in Conf/server.xml

<valve classname= "Org.apache.catalina.valves.AccessLogValve" directory= "/home/richmail/logs/tomcat"

prefix= "Localhost_access_log" suffix= ". txt"

pattern= "%h%l%u%t &quot;%r&quot; %s%b "/>

7. Delete the Conf/logging.properties file 8. Start Tomcat.
