Note - After you done with Installation.

Login into EC2

Master -

$ - mongo
> rs.intiate()
> rs.add("ip-10-123-25-111.ap-southeast-1.compute.internal:27017")

How to scp EC2

Machine to EC2
scp -i myAmazonKey.pem FILE ubuntu@mec2-50-17-13-12.compute-1.amazonaws.com:~/.

EC2 to local
scp -i ec2key.pem username@ec2ip:/path/to/file .

TAR File

tar cvzf nameoffiletocreate.tar.gz locationthatyouwant

example - tar cvzf harish.tar.gz /ubuntu/harish/Desktop/

Unrar TAR File

tar -xvzf harish.tar.gz

Single bucket policy

For Multiple Bucket

{
       "Version": "2012-10-17",
   "Statement": [
       {
           "Effect": "Allow",
           "Action": "s3:*",
           "Resource": [  "arn:aws:s3:::harish/*",

Find server Machine IP with NGINX LUA

Step 1 install

wget http://openresty.org/download/ngx_openresty-1.7.10.2.tar.gz
tar xvzf ngx_openresty-1.7.10.2.tar.gz
cd ngx_openresty-1.7.10.2/
sudo apt-get update
sudo apt-get install libreadline-dev libncurses5-dev libpcre3-dev libssl-dev perl make build-essential
./configure --with-luajit
make
sudo make install
mkdir ~/work
cd ~/work/
mkdir conf/ logs/
vim conf/nginx.conf
PATH=/usr/local/openresty/nginx/sbin:$PATH
export PATH
nginx -p `pwd`/ -c conf/nginx.conf
curl localhost:8080

Step 2
Note - use step 2 only if you want to use content by lua and skip step 3,4
## content by lua
worker_processes  1;
error_log logs/error.log;
events {
    worker_connections 1024;
}
http {
    server {
        listen 8080;
        location / {
            default_type text/html;
            content_by_lua '
                ngx.say("<p>hello, world</p>")
            ';
        }
    }
}

Step 3
Note - use this if you want to use content by lua file in this skip step 2
## content by lua file
worker_processes  1;
error_log logs/error.log;
events {
    worker_connections 1024;
}
http {
    server {
        listen 8080;
        location / {
            default_type text/html;
            content_by_lua_file '/home/mr/cache.lua';
        }
    }
}

Step 4
Note - lua file that you want to pass from nginx
## content by lua file
vim /home/mr/cache.lua                
ngx.print(ngx.var.remote_addr)

Step 5
Note - if any isssue to start the nginx
Trobleshoot -
ps ax| grep nginx
sudo kill -9 PID

Step 6
Note - how to start nginx and open on browser IP:8080
Start ->
nginx -p `pwd`/ -c conf/nginx.conf
curl localhost:8080

How to setup mongodb replSet

Master IP - 172.31.9.122

Note - Be Carefull and change according.

Step 3 - Login into mongo

mongo --host 172.31.9.122

>

rs.initiate(
{_id: "harish",
  members: [
    {
      _id: 1,
      host: "ip-172-31-9-122.ap-southeast-1.compute.internal",
      arbiterOnly: false,

Login to you master mongo
mongo --host 172.31.9.122
>
 rs.add('ip-172-31-17-152.ap-southeast-1.compute.internal:27017')

Speed testing your website with Siege Automatic

Installation via Homebrew

First, install homebrew using the instructions from https://github.com/mxcl/homebrew/wiki/installation. Once installed you can simply install Siege in one command:

$ brew install siege

Using Siege

Now that Siege is installed we can begin speed testing your website. First thing to do is to create the siege config file in your home directory.

~ $ siege.config 

 
New configuration template added to /home/andrew/.siegerc
Run siege -C to view the current settings in that file

~ $ siege -c10 -d10 -r1 -v http://www.harish.com/ 

** SIEGE 2.72 

** Preparing 10 concurrent users for battle.  

The server is now under siege...

done. 

Transactions: 10 hits Availability: 100.00 % Elapsed time: 8.12 secs Data transferred: 0.04 MB Response time: 0.11 secs Transaction rate: 1.23 trans/sec Throughput: 0.00 MB/sec Concurrency: 0.14 Successful transactions: 10 Failed transactions: 0 Longest transaction: 0.13 Shortest transaction: 0.11

Let’s break this down a little. First we entered the siege command with a number of parameters:

• -c10 is the number of concurrent users we want to simulate.
  

• -r1 is the number of repetitions, in this case, 1.
  

• -d10 is the delay between each user request (each siege simulated users sleeps for a random interval in seconds between 0 and 10).
  

-v is to show the output of each request.

Speed testing your website with Siege Manual

sudo apt-get install siege

 

$ curl http://www.joedog.org/pub/siege/siege-latest.tar.gz -o siege-latest.tar.gz $ tar xvfz siege-latest.tar.gz $ cd siege-2.72 $ ./configure $ make $ make install

This will install Seige to /usr/local/bin/siege.
