Tomcat Log Auto-segmentation (Linux) Cronolog

The log output of Tomcat on Linux is in Catalina.out, and as time goes by, the resulting log files will become bigger and larger, mainly in the debugging of some of the information printed in space, such as System.out and log and so on. Tomcat's Catalina.out file is constantly expanding, causing the system disk space edge to become smaller, also inconvenient to view, so use Cronolog by date to split the log (in the example of the split units in 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 the Cronolog is installed (verify that the installation was successful)

  # which Cronolog

  Normal display:

  /usr/local/sbin/cronolog

• To split Tomcat's catalina.out, you need to do the following:

  Previous versions of TOMCAT7:

  (1) Comment out (#)

  Touch "$CATALINA _base"/logs/catalina.out

  (2) Modify two of the catalina.sh files in the Tomcat bin directory

  Org.apache.catalina.startup.Bootstrap "[email protected]" start \

  >> "$CATALINA _base"/logs/catalina.out 2>&1 &

  For

  Org.apache.catalina.startup.Bootstrap "[email protected]" Start 2>&1 \

  | /usr/local/sbin/cronolog "$CATALINA _base"/logs/catalina.%y-%m-%d.out >>/dev/null &

• When you are finished, you can restart Tomcat to see the catalina.out.2015-09-13 style log in the logs file.

• TOMCAT7 later versions:
  1 First Step

  Will

  If [-Z "$CATALINA _out"]; Then

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

  Fi

  Revision changed to

  If [-Z "$CATALINA _out"]; Then

  
  catalina_out= "$CATALINA _base"/logs/catalina.%y-%m-%d.out

  Fi

• 2 Step Two

  Will

  Touch "$CATALINA _out"

  Switch

  #touch "$CATALINA _out"

• 3 Step Three

  Will

  Org.apache.catalina.startup.Bootstrap "[email protected]" start \

  >> "$CATALINA _out" 2>&1 &

  Revision changed to

  Org.apache.catalina.startup.Bootstrap "[email protected]" Start 2>&1 \

  | /usr/local/sbin/cronolog "$CATALINA _out" >>/dev/null &

• or perform the following procedure as follows (recommended):

# VI bin/catalina.sh

Find the following line

Org.apache.catalina.startup.Bootstrap "[email protected]" start \
>> "$CATALINA _out" 2>&1 &

There are 2 lines like this, the first is Tomcat with the "-security" parameter of the start, the second is the default Tomcat boot mode, which is the other part of the other, we only modify here.

In addition, the touch "$CATALINA _out" this line commented out.

The complete changes are as follows:

#touch "$CATALINA _out"

If ["$" = "-security"]; Then

........

Else

Eval "\" $_runjava\ "" \ "$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 "[email protected]" Start 2>&1 \

| /usr/local/sbin/cronolog "$CATALINA _base"/logs/catalina.%y-%m-%d.out >>/dev/null &

Fi
