In windows, ARR of IIS is used to achieve site load balancing and arr load balancing.

In windows, ARR of IIS is used to achieve site load balancing and arr load balancing.
1) Purpose:

Access localhost: 18066

Load the following two ports

Localhost: 18098

Localhost: 18099

 

2) means:

1. Use nginx

2. Use the ARR (Application Request Routing) of iis)

 

3) use the ARR of IIS

Steps:

1. Deploy porxy site port 18066,

Used for forwarding.

Note:

Set "idel time-out" of the corresponding application pool to 0.

The recovery time needs to be adjusted to 0.

 

 

 

2. Deploy two sites that actually provide services

Ports 18099 and 18098 are configured as needed.

3. Install ARR,

Address (https://www.iis.net/downloads/microsoft/application-request-routing)

4. Set Server Farms

For example, you must specify a port when adding a server. Note: For duplicate addresses, add mappings in windwo \ system32 \ drivers \ ect \ hosts to avoid duplication.

For example:

127.0.0.1 site1host

127.0.0.1 site2host

5. Configure the specified porxy port to use the corresponding Server Farms.

(If this parameter is not specified, all listener ports on iis will use Server Farms to cause an error)

　　

　　

 

6. Test

Access http: // localhost: 18096/aaa.txt

After configuring the rotation load policy, we can see the corresponding content returned by the two servers.

 

4) Appendix:

Performance Comparison of the three access conditions, using the apache benchmark tool,

The performance of iis arr on the same server is similar to that of direct site access.

In the same way on the same server, the performance of nginx (windows) is only about 1/3.
