Log rotate (catalina.out) of Tomcat

Rotate Catalina.out of tomcat on On Linux (Centos 7) server


By default, Catalina.out file will not be rotated. To rotate it I have used logrotate.

First, understand the logrotate utility 


  1. Create tomcat file under /etc/logrotate.d/ using below command                               sudo vi /etc/logrotate.d/tomcat
  2. Press i to enable insert mode, past below script into file                                                               
    /opt/app/tomcat/logs/catalina.out {
     su myuser myusergroup
     missingok
     notifempty
     copytruncate
     daily
     size 5M
     rotate 7
    }    Here /opt/app/tomcat/logs/catalina.out is path to your log file.
  3. press Esc key, then :wq! to write and quite (save) the file

Daily /etc/logrotate.conf will run which also include our tomcat file. So our log will be rotated next day.  To test everything configured well we can run below command with the debug mode (-d). Which won't affect any file just to debug. If you want to really test file rotation then run the same command with -v option

/usr/sbin/logrotate -d /etc/logrotate.d/tomcat


If your file is rotated when you run above command manually with -v option, but not rotating automatically with daily cron then you can try configuring crontab with your required schedule.


sudo crontab -u root -e

save the file with below cron

Everyday 1 AM:

0 1 * * * /usr/sbin/logrotate -v /etc/logrotate.d/tomcat  >/dev/null 2>&1


Everyday 11 PM and 1 AM:

0 1,23 * * * /usr/sbin/logrotate -v /etc/logrotate.d/tomcat  >/dev/null 2>&1

Git Auto Increment tag

If you want GIT tag autoIncrement with one version number after each build you can use below shell script(./gittag.sh) as the hook. Scrip will find last committed TAG which starts with  ENV_TAG_PREFIX ( QA_V) and creates next release TAG then push tag to GIT. VERSION_MODE   [major|minor|revision|buildNumber - These are the possible value. each time one version is a tag with GIT. By default, buildNumber is pass which increment last digit in release tag like(x.x.x.1 to x.x.x.2). So if you want major release then you can pass major as option which tag GIT with major release  like (1.x.x.x to 2.x.x.x)] e.g. ./gittag.sh major       ./gittag.sh minor #!/bin/bash VERSION_MODE = $1 ENV_TAG_PREFIX = QA_V # "major": 1, # "minor": 0, # "revision": 0, # "buildNumber": 1 if [ "$VERSION_MODE" = "" ] ; then VERSION_MODE = "buildNumber" fi cd /path/to/your/git/checkout ...

Bypass SSL certificate check for Apache Axis2 client

For some reason, I wanted to totally ignore the certificate and trust store check with my Axis2 client stub implementations and I was looking for the solution. I came across a lot of articles which states about using  HttpsURLConnection to disable SSL check, but the problem is underlying Axis2 client doesn’t use the  HttpsURLConnection  Solution: We can use that TrustManager to create an SSLContext which trust all the servers. SSLContext sslCtx = SSLContext . getInstance ( "TLS" ); sslCtx . init ( null , new TrustManager [] { new TrustAllTrustManager ()}, null ); APIStub client = new APIStub ( url ); client . _getServiceClient (). getOptions (). setProperty ( HTTPConstants . CUSTOM_PROTOCOL_HANDLER , new Protocol ( "https" , (ProtocolSocketFactory) new SSLProtocolSocketFactory ( sslCtx ), 443 ));
