Tomcat log Cleanup (with extension accesslogvalve)

1 , Tomcat's access log accesslogs regular or quantitative deletions

a turn on the Tomcat access log

Edit the ${catalina}/conf/server.xml file. Note: ${catalina} is a Tomcat installation directory

Remove the following comments (<!---->).

<!--<valveclassname= "Org.apache.catalina.valves.AccessLogValve"

directory= "Logs" prefix= "Localhost_access_log." suffix= ". txt"

pattern= "Common" resolvehosts= "false"/>-->

Open the Access log for the profile and interpret the corresponding parameters:

b Extend the accesslogvalve by override this Function:log (), set up periodic or quantitative delete access logs

 Public voidEmptyfile () {String LogPath= System.getproperty ("Catalina.base"); //Rotatable=false, quantitative purge only one log file Localhost_access_log.log        if( This. rotatable = =false) {            synchronized( This) {System.out.println ("------Log size is------:" + This. Currentlogfile.length ()); if( This. Currentlogfile.length () > 10 * 1024) {                     This. Currentlogfile.delete ();                Open (); }            }        } Else {            //log cleanup with date '//Localhost_access_log.2016-12-16.23.37.log//Localhost_access_log.2016-12-16.23.39.log            if(NewFile (LogPath). Isdirectory ()) {                //get a collection of files in a folderfile[] Logs =NewFile (LogPath). Listfiles (); //set the date format set here, consistent with the parameters in the configuration fileSimpleDateFormat DateFormat =NewSimpleDateFormat ("yyyy-mm-dd.hh.mm"); //iterating through the collection                 for(inti = 0; i < logs.length; i++) {File log=Logs[i]; //get the name of the I log, intercept the middle date field, and turn it into a long type S                    intStart = Log.getname (). IndexOf (".") + 1; intEnd = Log.getname (). LastIndexOf ("."); //gets the time in the log name (2016-12-16.23.37)String Datestr =logpath.substring (start, end); //converts a String type (2016-12-16.23.37) to a long type                    LongLonint = 0; Try{lonint=Dateformat.parse (DATESTR). GetTime (); } Catch(ParseException e) {//TODO auto-generated Catch blockE.printstacktrace (); } System.out.println ("------Old-log date is------:" +lonint); //system time minus log name gets more time lag than set in config file delete                    if((System.currenttimemillis ()-Lonint)/($ *) > 10) {log.delete ();                    Open (); }                }            }        }    }

2 , Tomcat's normal log (catlina.out, localhost) configuration log4j log framework for log rollback

Log4j Configure the Tomcat logs to be deleted periodically:

First, you need to download a 3 jar package.

Tomcat-juli.jar and Tomcat-juli-adapters.jar, Log4j.jar

http://www.apache.org/dist/logging/log4j/1.2.17/

http://www.apache.org/dist/tomcat/tomcat-7/v7.0.69/bin/extras/

The directory where 3 jar packages are placed at a time is:

Tomcat-juli-adapters.jar and Log4j.jar into the ($CATALINA _base/lib) directory

Tomcat-juli.jar into the $CATALINA _base/bin/directory, directly covering the original Tomcat-juli.jar can be

Delete the $catalina_base/conf/logging.properties file to prevent Java.util.logging from generating a 0-length log file.

Modify the Conf/context.xml file in Tomcat to <Context> <context swallowoutput= "true" >.

Finally, create a log4j.properties in the Tomcat6.0.43/lib directory, add the following and save:

(Here is an example of regular cleanup of catalina.out)

Log4j.rootlogger = INFO, CATALINA

INFO, MANAGER

Log4j.logger.org.apache.catalina.core.ContainerBase. [Catalina]. [localhost]. [/host-manager] =\

INFO, Host-manager

Reboot Tomcat and you'll see Java-djava.util.logging.config.file turned into Java-dnop-djava.util.logging.config.file, indicating that the configuration was successful.

The effect is as follows:
