Practice steps: First: On the local server (10.60.44.126), create a website using the port 808, for example: IIS website binding settings Second: Create a website in the Remote IIS

Next, this section describes the network architecture and configuration process of the RADWARE project. Radware works in active/standby mode. The corresponding networking methods are divided into single-arm networking, dual-arm networking, and triangular transmission. I. Single-arm networkingThe following networking is called single-arm networking, which is a widely used networking method. This networking mode enables complete master-slave switchover. Generally, the gateway of the server must po

Even better, nginx can immediately identify servers A and B. If the response time of A is 3, if the response time of B is 1, nginx automatically adjusts the probability of access to B to three times t

For Web application cluster learning, I started from tomcat5.5. Below are some of my practical operations and experiences.

In this example, I will configure a cloud service Travelweb, which has two VMs, which together provide HTTP services1. Create the first VM TRAVELWEB01, specify the cloud service name as Travelweb when you create it, add an HTTP endpoint2. Create a second VM TRAVELWEB02, using the existing cloud service TravelwebAt this point, both VMs are under the same cloud ser

session application server. In this case, the nginx backend can only direct to the application server, or create another squid and then point to the application server. The best way is to use location for one-time traffic distribution. part of the requests that require session are distributed through ip_hash, and the rest are distributed through other backend servers.4) upstream_hashTo solve ip_hash problems, you can use upstream_hash, a third-party

are performed on the slave database instance. For example, if a user comments a blog post and directly uses the slave database, it may not be completed because the MySQL replication architecture lags behind, at this time, the blog post may not be available from the database. Checking outdated data is a better way. if you have a report query that runs at night, this method may work well. you just need to make sure that the replication can catch up with the progress. Another method is to track da
