Tomcat uses log4j for log Segmentation

Because tomcat catalina. out logs are not automatically split,
1. The package required for log splitting is nearby
1. Three jar packages in the compressed package: log4j-1.2.16.jar tomcat-juli-adapters.jar tomcat-juli.jar
(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,: http://www.apache.org/dist/tomcat in the corresponding version of the bin/extras path)2. Modify related configuration files
1. Modify $ {catalina. home}/conf/context. xml modification: <Context> <Context swallowOutput = "true"> only in this way can the stdout of tomcat be completely taken over. 2. Copy the log4j-1.2.16.jar and tomcat-juli-adapters.jar to tomcat's lib. 3. Copy the tomcat-juli.jar to $ {catalina. home}/bin, the file exists in this directory, overwrite it. 4. Create log4j. properties, and put it under tomcat/lib Log4j. properties: The parameters can be modified as needed.

5. modify bin/catalina. sh. block or delete the following content: (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. Modify org. apache. catalina. startup. Bootstrap "$ @" start \ content (two parts)
Changed 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.
