How to build SOAP mock service using SOAP UI

Here I have described step by step guidelines to create SOAP mock service using SOAP UI

Prerequisites:

• SOAP UI
• Simple SOAP WS (we are going to mock this service)

STEP 01:

Right click on your SOAP project interface and go to "Generate SOAP Mock Service"

STEP 02:

 Here you can design your mock service. eg: path, port, operation, etc And then click OK.

 STEP 03:

Your MOCK service has been created. Now you can define the response as below.

 STEP 04:

 Once updated, you can start the MOCK service.

 STEP 05:

 Now your MOCK service is running on given port

 STEP 06:

 Now you can trigger MOCK service using SOAP UI and see the configured response.

 STEP 07:

 You can see the log in start window as well.

Find if a SSL certificate is self signed or CA signed

Try below command for .pem certificate file

       
openssl x509 -in certificate.pem -inform PEM -noout -subject -issuer
       

If subject and issuer are same : It is self signed certificate
If subject and issuer are different : It is CA signed certificate and issuer will be CA

How to remove ssh-agent process in redhat

When you log out, you want the ssh-agent process to be terminated automatically.

You can add below command in .bash_profile file

trap 'test -n "$SSH_AGENT_PID" && eval `/usr/bin/ssh-agent -k`' 0

If you need to remove existing processes,

for(( ; ; )); do kill $(ps -ef | grep ssh-agent | grep -v grep  | grep -v grep | awk -F' ' '{print($2)}' | head -1 );echo "done"; done

Mysql Load Balancing with Nginx (Ubuntu)

Environment setup:

Mysql master server : 192.168.1.10
Mysql slave server : 192.168.1.12

Nginx server : 192.168.1.14

1. Add Nginx configurations

Add below configuration to nginx main configuration file (/etc/nginx/nginx.conf) just after the http block     

stream {

    upstream mysql_cluster {

        server 192.168.1.10:3306; # node1

        server 192.168.1.12:3306 backup; # node2

    }

    server {

        listen 3306; 

        proxy_pass mysql_cluster;

    }

}

2. Open 3306 port in Nginx server

Since we are using 3306 port, we need to use SELinux and open port privileges

Try below command in Nginx server

sudo semanage port -l | grep http_port_t

check port 3306 is there, if not we can add it by using below command

sudo semanage port -a -t http_port_t  -p tcp 3306 

3. Enable firewall

 If you are using CentOS, you may use below command to enable firewall rules in Nginx server

firewall-cmd --zone=public --add-port=3306/tcp --permanent

firewall-cmd --reload

Import SSH private key file to Xshell

You can follow below steps to import ssh private key to Xshell successfully.

1. Open putty-keygen and import the private key.

2. Once loaded, Go to "Conversions" and then "Export OpenSSH Key"

3. Then choose a location to save the private key file and click "Save".

4. You will be able to import above private key file to Xshell.

Simple HTTP Listener using Python

Here is a simple HTTP listener using Python BaseHTTPRequestHandler 
This Application will,

• listen to port 8000 on localhost
• respond to REST POST request 

from BaseHTTPServer import BaseHTTPRequestHandler
import urlparse, json
import shutil
import os

class GetHandler(BaseHTTPRequestHandler):

	def do_POST(self):

		content_len = int(self.headers.getheader('content-length'))
		req_token = self.headers.get('Authorization')
		post_body = self.rfile.read(content_len)
		data = json.loads(post_body)
		user_id = data['id']
		user_name = data['name']
		
		print ("Token "+str(req_token))
		print ("User Id "+str(user_id))
		print ("User Name "+str(user_name))
		 
		#Do something here
		
		self.send_response(200)
		return

if __name__ == '__main__':
	from BaseHTTPServer import HTTPServer
	server = HTTPServer(('localhost', 8000), GetHandler)
	print 'Starting server at http://localhost:8009'
	server.serve_forever()

    
 

Save the content as simple_http_server.py

Start Application : python simple_http_server.py

Sample Request:

curl -v -X POST -H 'Authorization: Bearer gcfdgckuyebku7t56FHGVBKJHKJTY6' -d '{"id":"1234","name":"Hasitha"}' http://localhost:8000
