The Catalina.out file for Tomcat under Linux is too large, and the directory change resolution

method 1 -Split stream  

Use cronolog tool slicing tomcat cronolog a small tool for log slicing whose home page is in http://cronolog.org/ , we can also use it to slice apache .

This method is recommended as follows

Google a bit first. cronolog-1.6.2.tar.gz

1. Download cronolog-1.6.2.tar.gz

2. Installation

# tar ZXVF cronolog-1.6.2.tar.gz
# cronolog-1.6.2/configure
# make
# make Install

Get!

The default is installed under/usr/local/sbin/.

3. Configuration

That's the point.!!!

Found in tomcat/bin/catalian.sh
Org.apache.catalina.startup.Bootstrap "[email protected]" start \ >> "$CATALINA _base"/logs/catalina.out 2&1 &

Change the contents of the above to:
Org.apache.catalina.startup.Bootstrap "[email protected]" start \
|/usr/local/sbin/cronolog "$CATALINA _base"/logs/catalina.%y-%m-%d.out >>/dev/null 2>&1 &

It's changed. Restart

#./catalina.sh start

Now go and see the fruits of labor.

# ls/tomcat/logs/

You'll find a few more files like Catalina.2006.06.01.log under the logs.

Method 2-Script flow

It's just a matter of big file handling, a powerfulBashto take care of;
UseCronDaily to back up the currentCatalina.out, and then emptied his contents;

The reference script is as follows:

#!/bin/sh
y= ' date ' +%y "'
m= ' date ' +%m "'
d= ' date ' +%d "'
Cd/path/tomcat/logs
CP catalina.out catalina.out. $y $m$d
Echo
> Catalina.out
Exit
AttentionLinuxSystem ofCronWhether the service is started, is working properly, and where the script is stored (reason temporarily confidential)

Method 3-Wretched stream

Open itbinUnder the directorycatalina.shDocument, after all, is just aBashFile

Find out,Catalina.outA total of three occurrences;

Part:


Shift

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

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

echo "Using Security Manager"

Shift

"$_runjava" $JAVA _opts "$LOGGING _config" $CATALINA _opts \

-djava.endorsed.dirs= "$JAVA _endorsed_dirs"-classpath "$CLASSPATH" \

-djava.security.manager \

-djava.security.policy== "$CATALINA _base"/conf/catalina.policy \

-dcatalina.base= "$CATALINA _base" \

-dcatalina.home= "$CATALINA _home" \

-djava.io.tmpdir= "$CATALINA _tmpdir" \

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

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


if [!-Z "$CATALINA _pid"]; Then

Echo $! > $CATALINA _pid

Fi

else

"$_runjava" $JAVA _opts "$LOGGING _config" $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 \

>> "$CATALINA _base"/logs/catalina.out 2>&1 &
Personally think that's where it's writtenCatalina.outWhat about the other empty devices that he wrote?

Note Before modifying the original filecatalina.shThe backup yo~！！

Modify the code in the above

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

>>/dev/null 2>&1 &
Save, and then startTomcat, the currentCatalina.outIt's been empty all the time.

This method is I think of myself, personally think more brave, not yet in the production environment tested. The virtual machine test is passed.

Method 4-flow of people

This method is actuallyLinuxThe system administrator manually remove, manual operation, referred to as "flow";

best to stop before deletingTomcatof services;
