Install XAMPP in Ubuntu

 

xampp

 

1. Download latest version o XAMPP from apachefriends.org. In my case, it is 64bit version of Linux operating system

Once you downloaded, you cannot install it as simple as that, just follow 1 more step ahead of your installation procedure.

2. open Terminal (Ctrl + Alt +t). Make sure to specify the location of your downloaded file. In my case, it is ‘Downloads’ folder

sudo chmod +x Downloads/xampp-linux-x64-5.6.3-0-installer.run

3. Complete rest of the installations.

If you would like to stop and start XAMPP only when necessary, then remember these commands

To Start – sudo /opt/lampp/lampp stop

To Stop – sudo /opt/lampp/lampp start

Generate CSR for SAN Certificate – Tomcat

This article assist you with step-by-step procedure to generate CSR for SAN Certificate (multiple domains) in Tomcat Server

3. Execute

  • Specify any alias name, here I specified ‘server’
  • Keysize must be specified, otherwise keytool will generate a key which is 1024 bit and it doesnt meet the minimum requirement
  • For the question “What is your first and last name?”, enter the domain name that you need certificate and not your actual first and last name!

4. After entering all the details, you will notice that keystore is created in e:\ssl_key folder

5. Now generate CSR.

keytool -certreq -alias server -file e:\ssl_key\hackandsecure.csr -keystore e:\ssl_key\hackandsecure

Notice that I have used the another domain name whi
