Ansible Installation on Ubuntu

Ansible on Ubuntu

Step 1 : Install
Here we'll use the ppa:ansible/ansible repository as it is easy to remember.

# apt-get-repository -y ppa:ansible/ansible
# apt-get update
# apt-get install -y ansible
Step 2 : Managing Servers
Ansible has a default inventory file used to define which servers it will be managing. After installation, there's an example one you can reference at /etc/ansible/hosts. I usually copy and move the default one so I can reference it later:

# mv /etc/ansible/hosts /etc/ansible/hosts.orig
Then I create my own inventory file from scratch. 
After moving the example inventory file, create a new /etc/ansible/hosts file, and define some servers to manage.  Here's we'll define two servers under the "web" label:

[web]
192.168.1.50
192.168.1.51
For testing this article, I created a virtual machine, installed Ansible, and then ran Ansible Tasks directly on that server. To do this, my hosts inventory file simply looked like this:

[local]
127.0.0.1

Troubleshooting Tomcat using Catalina log

Troubleshooting Tomcat using Catalina log We can get the  catalina  logs in  $CATALINA_HOME/logs Here we'll have a  catalina.out We can see some huge info in that log file. If we want to what exactly happens since the start of tomcat then we need to log that into a new file. By default we have log rotation enabled on this logs. For now let us stop tomcat and nullify the catalina.out file and then start tomcat to have some new info in the catalina.out # service tomcat stop # cd $CATALINA_HOME/logs # :> catalina.out (or) cat /dev/null > catalina.out # ll catalina.out -rw-r----- 1 root root 0 Feb 18 16:19 catalina.out # service tomcat start # ll catalina.out -rw-r----- 1 root root 17341 Feb 18 16:21 catalina.out We can see the log being written after the start of tomcat. Now we can notice the instance giving some information about the starting of tomcat, about the configuration for the startup, path of the servlet instance for which the log is re...

Managing tomcat application

Tomcat is a servlet application which is ready to use after download. There is no need of installing this application. We can directly start or stop it from the bin directory.  So in such case we should go to the bin directory in the CATALINA_HOME or else we need to use the startup script along with its absolute path. And the same is needed to shut it down. We can use the below script to manage the tomcat application and we neither need to go to the CATALINA_HOME nor to use the absolute path. All we need to do is to change the permissions to make it executable and copy that to /sbin and /etc/init.d/ directories. If we copy this into /etc/init.d/ then also we need to mention the absolute path but we can easily memorize it as we know all the startup scripts exists there. But if we copy that into /sbin then there is absolutely no need of mentioning the path of the file. We can use this like below: # tomcat start|stop|restart|status #!/bin/bash # Author : Arjun S...
