Manage applications on Simple Application Server - Simple Application Server

After creating a simple application server based on an application image, view the preset application details and configure the application from the Simple Application Server console.

Prerequisites

A simple application server is created based on an application image. For more information, see Create a simple application server.

Important

The Application Details tab is available only for servers created based on an application image. Servers created based on an operating system (OS) image do not display this tab.

Open the Application Details tab

The following steps use the LAMP 6.1.0 application image as an example. The same procedure applies to other application images. The information displayed in the Simple Application Server console takes precedence.

Go to the Servers page in the Simple Application Server console.
Click the server ID in the server card to go to the Server Overview page.
Click the Application Details tab.

Information on the Application Details tab

The Application Details tab displays the following sections:

Section	Description
Image information	Server status and image version. If you encounter issues, click Contact the service provider or View image help documentation.
Application steps	Steps to build a website on the server.
Application information	Username, password, website root directory, and website home address.
Installation information	Installation details of the preset application.

Verify the Apache service (LAMP example)

On the Application Details tab, click the URL next to Home Address to check whether the server is configured correctly. If Apache is running, the default Apache page is displayed.

Retrieve the database password (LAMP example)

On the Application Details tab, click the copy icon next to Database Password.
Click Connect to open a remote connection window.
In the command line, paste and run the copied command to query the database administrator logon information.

Create a test web page (LAMP example)

This example creates a test web page on a LAMP server and verifies access through a browser.

In the LAMP Information section, find the website root directory /home/www/htdocs and click Connect.
Switch to the root user:
```
sudo su root
```
Go to the website root directory:
```
cd /home/www/htdocs
```
Create a test file named test.html and write test content to it:
```
touch test.html
echo 'Test001' >> test.html
```
Open a browser on your on-premises computer and go to http://<Public IP address of the simple application server>/test.html. If the page displays "Test001", the web page is accessible.

Apache restart behavior

Adding or deleting files in the website root directory does not require an Apache restart. Modifying the application configuration file requires an Apache restart for the changes to take effect.

Warning

Restarting the Apache service may interrupt your business. Perform this operation during off-peak hours.

Next steps

Upload website projects: Upload your actual website project files to the website root directory on the server.
Bind a domain name: To serve external traffic from your server, bind a domain name and resolve it. For more information, see Bind and resolve a domain name.
