To install apache2.4 in Windows 7, we first need to download the apache2.4 installation program. Here we download the software from the apache official website http://httpd.apache.org/download.cgi .

First, let's see how to download apache2.2 from the official website

Open the above URL and select 2.4.23 to download

Then we see the following page

Select Files for Microsoft Windows and click Enter

Apache itself does not provide compiled installation packages, only source code. If you cannot compile and install it yourself, you can choose the following officially recommended third-party compilation websites.

The last two are the famous wamp and xampp integrated environments. If you only want to download apache, you can choose the first three websites. Here we take the first ApacheHaus as an example. After clicking in, we can choose any one to download

Finally, just wait for the download to complete.

After the download is complete, it is time to install it. First, unzip the downloaded httpd-2.4.23-x64-vc14-r3.zip to the directory where we want to install Apache. Here we take D:/wamp as an example.

After the decompression is successful, there will be an Apache24 directory in the D:/wamp directory. This contains all the files of our apache2.4. Let's see how to install it.

First, we open the cmd command line, enter the D:/wamp/Apache24/bin directory, and run the following command:

D:\wamp\Apache24\bin> httpd –k install

The function of this command is to install the Apache service as a Windows background service. If there are no special circumstances, the command can run normally. However, in most cases, an error message will appear indicating that VCRUNTIME140.dll is missing, causing our service to fail to install normally. However, don't be too nervous if this error occurs. This is because the latest version of Apache under Windows requires the Microsoft Visual C++Redistributable 2015 component. This component may have been installed in our system before, but the version may be 2008. What we need here is a higher version. Therefore, we can download it from the following address:

https://www.microsoft.com/en-US/download/details.aspx?id=48145

After the installation is successful, run the above command again to succeed. If the following result appears, it means that our Apache backend service has been installed successfully.

Installing the 'Apache2.4' service
The 'Apache2.4' service is successfully installed.
Testing httpd.conf....
Errors reported here must be corrected before the service can be started.
httpd: Syntax error on line 39 of D:/wamp/Apache24/conf/httpd.conf: ServerRoot m
ust be a valid directory

Yes, the Apache backend service has been installed successfully. But let's see if there is an error at the end of the above information. The error message tells us that the service root directory in the Apache configuration file httpd.conf is an invalid directory. If we ignore the error and start the Apache service directly, it will definitely fail to start.

Here we can use ApacheMonitor to start

D:\wamp\Apache24\bin>ApacheMonitor.exe

Run the above command, and we will see a feather-shaped icon appear in the lower right corner. Yes, that is the classic Apache icon - ApacheMonitor

The following error message will appear during our startup process

We can see that the startup failed. So for the error message above, we must first solve the error.

Open D:/wamp/Apache24/conf/httpd.conf and find the following two lines

Define SRVROOT "/Apache24"
ServerRoot "${SRVROOT}"

We can see that the path after SRVROOT is invalid. Because our service directory is in D:/wamp, so we need to change that directory

Define SRVROOT "D:/wamp/Apache24"
ServerRoot "${SRVROOT}"

Save and exit and then restart the apache service

Let's see if it has been successfully started.

Open our browser and enter localhost, the following page will appear

This means that our Apache service has been installed successfully and can run normally, providing services for our applications.
