There is four major version of IHS available.

IBM HTTP Server 6.0 IBM HTTP Server 7.0 IBM HTTP Server 8.0 IBM HTTP Server 8.5

Knowing which version is installed on your server is essential for technical stack auditing and ensuring you have the latest version. Here are two ways to find out the installed IBM HTTP Server version and Architecture.

Find through versionInfo.sh

Probably the most reliable and best way to find the version installed on the server.

Log in to the IBM HTTP Server Go to the path it’s installed Go to the bin folder and execute below file

To know the architecture, you can use below grep So now you know it’s 8.5.5.9 with 64 bit in above example.

Check the IHS version through log file

If you are not into production support then you may not have the server access to execute versionInfo.sh file to see the version. In this situation, assuming you have access to the log file you can use following technique. Login into IBM HTTP Server and access the path where IHS logs are generated View the error_log file and look at the startup line, it should read the version under notice as shown below. Note: log file will not have the architecture details. If you are looking to find out the IBM HTTP Server historical versions on the server then you can use historyInfo.sh. I hope above procedure helps you to find the IBM HTTP Server version and architecture level.
