Cronolog separates Tomcat catalina. out logs

Cronolog separates Tomcat catalina. out logs
Tomcat logs are output in catalina. as time passes, the generated log files become larger and larger. The main reason is that some information printed during debugging occupies space, such as System. out and log. The catalina. out file of tomcat is constantly expanding, which makes the disk space edge of the system small and inconvenient to view. Therefore, cronolog is used to split logs by date (in this example, the logs are separated by days ).

• Cronolog Installation

1. # tar zxvf cronolog-1.6.2.tar.gz# cd cronolog-1.6.2# ./configure# make# make install

• Check the directory where cronolog is installed (verify that the installation is successful)

  # Which cronolog

  Normally:

  /Usr/local/sbin/cronolog

• To split catalina. out of tomcat, you need to do the following:

  Versions earlier than Tomcat 7:

  (1) Comment out (#)

  Touch "$ CATALINA_BASE"/logs/catalina. out

  (2) modify the catalina. sh file in the tomcat bin directory.

  Org. apache. catalina. startup. Bootstrap "$ @" start \

  > "$ CATALINA_BASE"/logs/catalina. out 2> & 1 &

  Is

  Org. apache. catalina. startup. Bootstrap "$ @" start 2> & 1 \

  |/Usr/local/sbin/cronolog "$ CATALINA_BASE"/logs/catalina. % Y-% m-% d. out>/dev/null &

• After that, restart Tomcat to view the logs in catalina. out.2015-09-13 format in the logs file.
• Versions later than Tomcat 7:
  1 step 1

  Set

  If [-z "$ CATALINA_OUT"]; then

  CATALINA_OUT = "$ CATALINA_BASE"/logs/catalina. out

  Fi

  Change

  If [-z "$ CATALINA_OUT"]; then

  
  CATALINA_OUT = "$ CATALINA_BASE"/logs/catalina. % Y-% m-% d. out

  Fi

• 2 Step 2

  Set

  Touch "$ CATALINA_OUT"

  Change

  # Touch "$ CATALINA_OUT"

• Step 3

  Set

  Org. apache. catalina. startup. Bootstrap "$ @" start \

  > "$ CATALINA_OUT" 2> & 1 &

  Change

  Org. apache. catalina. startup. Bootstrap "$ @" start 2> & 1 \

  |/Usr/local/sbin/cronolog "$ CATALINA_OUT">/dev/null &
• Or perform the following steps to achieve the same effect (recommended ):

# Vi bin/catalina. sh

Find the following line

Org. apache. catalina. startup. Bootstrap "$ @" start \
> "$ CATALINA_OUT" 2> & 1 &

There are two rows like this. The first is tomcat startup with the "-security" parameter, and the second is the default tomcat startup mode, that is, the part below else, we only need to modify it here.

In addition, you need to comment out the "$ CATALINA_OUT" line of touch.

The complete modification is as follows: # touch "$ CATALINA_OUT" if ["$1" = "-security"]; then ........ elseeval "\" $ _ RUNJAVA \ "\" $ LOGGING_CONFIG \ "" $ LOGGING_MANAGER $ JAVA_OPTS $ CATALINA_OPTS \-Djava. endorsed. dirs = "\" $ JAVA_ENDORSED_DIRS \ ""-classpath "\" $ CLASSPATH \ "" \-Dcatalina. base = "\" $ CATALINA_BASE \ "" \-Dcatalina. home = "\" $ CATALINA_HOME \ ""-Djava. io. tmpdir = "\" $ CATALINA_TMPDIR \ "" \ org. apache. catalina. startup. bootstrap "$ @" start 2> & 1 \ |/usr/local/sbin/cronolog "$ CATALINA_BASE"/logs/catalina. % Y-% m-% d. out>/dev/null & fi

After that, restart Tomcat to view the logs in catalina. out.2015-09-13 format in the logs file.
