Solve the problem that Tomcat Catalina. Out keeps growing, leading to excessive Archives

Method 1-stream Separation

Use cronolog to split Tomcat's Catalina. Out Log File

Cronolog a small tool for log splitting, its home page in http://cronolog.org/(but found that this domain name has expired, you can download the http://download.csdn.net/detail/wayne173/8096321 here ),, we can also use it to split Apache logs.

This method is recommended as follows:

1. Download cronolog-1.6.2.tar.gz

2. Installation

# Tar zxvf cronolog-1.6.2.tar.gz
# Cronolog-1.6.2
# Cd configure
# Make
# Make install

Done!

Installed in/usr/local/sbin/by default.

3. Configuration

The point is. Note !!!

In tomcat/bin/catalian. Sh, find
Org. Apache. Catalina. startup. Bootstrap "[email protected]" Start \> "$ catalina_base"/logs/Catalina. out 2 & 1 &

Change the above content:
Org. Apache. Catalina. startup. Bootstrap "[email protected]" Start \
|/Usr/local/sbin/cronolog "$ catalina_base"/logs/Catalina. % Y-% m-% d. Out>/dev/null 2> & 1 &

Modified. Restart

#./Catalina. Sh start

Now let's take a look at the labor results.

# Ls/tomcat/logs/

You will find several more files under logs, such as catalina.2014.10.28.log. The Catalina. Out file also exists, but the size is always 0.

Method 2-script stream

After all, this is just a big file processing problem. It can be done with powerful Bash;
Use cron to back up the current Catalina. out every day, and then clear its content;

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
Check whether the cron service in Linux is started, whether it works properly, and the script storage path (the reason is confidential for the moment)

Method 3-refer to the cumbersome stream

Open the Catalina. Sh file in the bin directory. After all, it is just a bash file,

Find out, Catalina. Out appears three times in total;

Part:


Shift

Touch "$ catalina_base"/logs/Catalina. Out

If ["$1" = "-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 &
In my opinion, this is where the Catalina. Out file is written. How can I write it to another empty device?

Note the backup of Catalina. Sh in the original file before modification ~!!

Modify

> "$ Catalina_base"/logs/Catalina. out 2> & 1 &
Is

>>/ DEV/null 2> & 1 &
Save and start Tomcat. Currently, this Catalina. Out is empty.

I think this method is brave and has not been tested in the production environment yet. Virtual Machine testing is successful.

Method 4-People Flow

In fact, this method is manually deleted by the Linux system administrator ";

It is best to stop Tomcat services before deleting them;
