Recently, the project needs to load the rewrite module dynamically in the compiled Apache. As a result, we found a lot of information on the Internet, but it was not very detailed and the format mismatch problem was serious. Therefore, it is necessary to repeat this process. The procedure is as follows: Job description:Linux 2.4.21The decompressed directory of apache_1.3.34.tar.gz is/root/apache_1.3.34"Apache installation directory/usr/local/Apache is abbreviated as "target directory" Steps:1.

This article is the second article in the series of "implementing key-Value Pair storage" Original article from Emmanuel goossaert (codecapsule.com) At the beginning of this article, I will explain the reasons for using an existing model instead of starting the project with a heavy header. I will elaborate on a series of criteria for selecting a key-Value Pair storage model. Finally, I will give an overview of some well-known key values on the Storage Project, and use these standards to select

ways to set session cache: DBM (dbm), a common pattern for storing items on disks (htpasswd can store passwords in DBM format) Shared memory cache (shm or shmcb) Shared memory table (shmht) You must specify the file path when using the above options. When the DBM variable is applied, the file is written into the d

The underlying values need to be remembered and then calculated based on this. Example: 0DBM

Python's data persistence operations are primarily six classes: normal files, dbm files, pickled object storage, shelve object storage, object database storage, relational database storage.Ordinary files do not explain, dbm is the string of key value pairs stored in the file:Python code% python >>> import anydbm >>> file = Anydbm.open (' movie ', ' C ') # make a

There are many ways to implement basic user identity authentication in Apache, such as the most common txt text and DBM pattern, but on servers with heavy loads-these are not imaginary methods, the text is flat-based, with poor performance and security. DBM is better, but it is still insufficient for thousands or tens of thousands of users. There are many ways to implement basic user identity authentication
