Run or deploy Go (Golang) project code in IIS as web server

 Hi folks,

Today we are going to see, how we can run or deploy the Go (Golang) project in IIS.

Development

1. Create your Golang project with web APIs
2. Build the Go project
3. Go build
4. Result will be an .exe file
5. Create a web.config file
6. Update the following content

<?xml version="1.0" encoding="utf-8"?>

<configuration>

    <system.webServer>

        <handlers>

            <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />

        </handlers>

        <aspNetCore processPath=".\<<GoProject>>.exe" />

    </system.webServer>

</configuration>

Deployment 

1. Place the <<GoProject.exe>> and web.config in IIS server accessible folder.
2. Open IIS
3. Create a new website
4. Enter the web app details with port different from the project internal port
5. Create or choose pool with .NET CLR version as "No managed code"
6. The configured website looks like below

Nginx Load Balancing Configuration

Hi folks,

I am going to explain the process of load balancing the web application using Nginx

Pre-requisites

• One machine with Nginx installation
• Two machines with running the same web application

Test setup

All are Ubuntu server machines

1. 10.10.1.1 - Load Balancer
2. 10.10.1.2 - Node 1
3. 10.10.1.3 - Node 2

Configuration

In the Nginx server machine (10.10.1.1) do the following load balancing configuration

• Make sure you stop the nginx server if running

$ sudo service nginx stop

• Edit the nginx.conf file 

$ sudo vi /etc/nginx/nginx.conf

• Place the following sample content

http {
        upstream testsetup {
        server 10.10.1.2;
        server 10.10.1.3;
}
    server{
        listen 8090;
        server_name testsetup;
        location / {
            proxy_pass http://testsetup;
        }
    }
}

• Start the Nginx server

$ sudo service nginx start

Load Balancing Test

1. Access the 10.10.1.1:8090 in the web browser
2. It will redirect to Node 1 (10.10.1.2)
3. Refresh/Reload the page, the load balancer redirects to Node 2 (10.10.1.3)

Tip

To differentiate the web server, add a footer with different content (Static IP Address) in your index.html

Load balancing with IIS ARR Server Farm

Hi Folks,

I am going explain how can you create a software load balancer with IIS Web Server.
This method is HTTP based load balancing.

2. Right click on "Server Farms" and select "Create Server Farm"
3. Give a name to the ServerFarm
4. You would be navigate to "Add Server" Page
5. Enter the application server/ip address and click on "Add"
6. Repeat again to add two or more servers
7. Check the status of the servers in "Server Address and Status" box
8. Click on "Ok"

Configure Load Balance

1. Select the created ServerFarm
2. Double click on the "Load Balance" item
3. Choose the following based on your requirement.
4. The default configuration as follows
• Load balance algorithm: Weighted round robin
• Load distribution: Even distribution

Based on the load balance algorithm, the load distribution options would be changed, if applicable.

Routing Rules Configuration

1. Select the created ServerFarm
2. Double click on the "Routing Rules" item

Monitor and Manage the servers

Deploy or Host ASP.NET Core web application in IIS

Dear folks,

Today I am going to explain the process of deploying the ASP.NET Core web application in IIS (Internet Information Services) web server.

Pre-requsites

• ASP.NET Core Runtime Hosting Bundle
• Navigate to https://dotnet.microsoft.com/download/dotnet-core/current/runtime
• Download Hosting Bundle to deploy [ASP].NET Core applications on a server

Application configuration

To make sure the application deploys and works with IIS, you should add the following while creating the web host.

WebHost.CreateDefaultBuilder(args)
                   .UseKestrel()
                   .UseIISIntegration()
                   .UseStartup();

 Where Kestrel hosts the application and IIS will be acting as a reverse proxy.

Publish the application

After doing the changes, publish the application to a folder as self-contained as you no need to bother about the server for all the application dependencies.

Web Configuration

• In Web.config, remove the following content
• hosting="In Progress"
• Copy files to IIS location
• Create a website folder in IIS wwwroot folder
• Copy the publish folder to the website folder
• Example: C:\inetpub\wwwroot\website

IIS Application Pool

• Create an application pool in IIS with following configuration
• Name:
• .NET CLR version: No Managed Code
• Managed pipeline mode: Integrated

Website Configuration

• Right click on the website and select "Add Application"
• Give the following details
• Alias:
• Application Pool: Select above created application pool from list
• Physical path: Select the above created website path
• Example: C:\inetpub\wwwroot\website

Restart IIS

• Once you have completed all the steps, perform the following to make sure everything is in sync.
• Open powershell in administrator mode
• Run the following commands
1. net stop was /y
2. net start w3svc

Test

Browse to the URL, you should be able to get the web pages.

2. Get the emsdk files

• git clone https://github.com/emscripten-core/emsdk.git

3. Navigate to the downloaded folder emsdk

• cd emsdk

4. Install (Note: On PowerShell execute this command, Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine)

• ./emsdk install latest

5. Activate

• ./emsdk activate latest

Create Sample HTML file

• Create folder
• mkdir hello
• Navigate to the folder
• cd hello
• Create a file hello.c and place the following code

#include
int main(int argc, char ** argv) { printf("Hello PSR!\n");}

Convert C file to HTML

emcc hello.c -o hello.html

Run WebServer (Optional)

Run emrun webserver to serve the html pages.

emrun --no_browser --port 8080 .
