Chantz's questions

I am building a solution where the CMS part of the site (i.e. About US, Contact etc) will be run on Wordpress & the private pages will be a Java-Servlet based stack run on Tomcat 7.

Both of these "apps" have to run on the same server for budget reasons, at least for now.

What I want to know how to make this happen (via configurations, setups etc)? So that whenever users come to public pages they will be served content from Wordpress but for private pages (here I am assuming there will be a URL pattern differentiating this) then it will be served by Tomcat

I am assuming here that I will be using Apache as the server for fronting the wordpress requests. Also it is an Ubuntu 12.04 server.

I am starting from scratch to launch a new Elastic Beanstalk environment using 64-Bit Amazon Lunix AMI version 2013.09. It is for tomcat 7 non-legacy container.

But after the environment is created and the instance has been launched, the URL (where the deployed app is supposed to be available) is not working.

I checked the instance itself & it seems that tomcat is not installed on it, let alone starting it. So I checked out the log file at /var/log/cfn-init.log and I saw some issues in it which might be causing this.

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

I dont understand whats up with this, have you faced these issues? If so how did you manage to resolve it.

I can also attach the complete log cfn-init.log if that helps.

One of my sites is hosted via Amazon EC2 service. The problem starts happening when the site faces a heavy load which in turn spawns a new EC2 instance via AutoScaling. This is good but the issue is when these instances are killed (due to lack of load) the session information is also lost, and hence forcing the user to re-login in to the site.

What is the best way to approach this problem?

I have looked in to Memcached Session Manager & it works fine for Sticky sessions but causing problems when I try to use Non-sticky sessions since I make a lot of parallel requests to my server.

My current server is Apache+Tomcat

Any pointers helpful. Thanks.

(cross post from webmasters.stackexchange)

Currently my site is entirely under https, but I do serve a lot of static content which does not necessarily need to be served via https. Platform I am using is Apache + PHP. What are the best practices for this?

I have certain portion of my site to be behind SSL which is reserved for registered users & want rest of the site which is open to public to be served by just http. Currently it is set up so that all the pages be it public or otherwise are served by https. Also botht he public & non-public content resides under the same webroot.

Can you guys suggest me a way to resolve this so or perhaps a best practice guide? Thanks!

EDIT

We use LAMP stack.
