PHP+Redis If you don’t pay attention to these details, you will simply jump into a pit that you can’t get out of (installation under windows)

Get straight to the point~~~~~~~

The first thing to do! Confirm version! Be sure to confirm your php version!

phpinfo Check out your current version. My current version is

You can see in the red areas that vc11 TS x86 has three key words:
vc11: It means that this version of php is written for the vc11 library;
TS: means thread safety NTS non-thread safety (I was here at the time, and I was stuck all afternoon because I didn’t pay attention to this when downloading things!!!);
About thread safety The difference between and non-thread safety (I found it from the Internet, if you want to know more, portal)

Starting from the first Windows version of PHP 3.0.17 released on October 20, 2000, all versions are thread-safe. This is because the Windows system uses a multi-process working method different from the Linux/Unix system. It adopts multi-threaded working method. If you run PHP in CGI mode under IIS, it will be very slow. This is because the CGI mode is based on multi-process, not multi-thread.

Generally we will configure PHP to run in ISAPI mode. ISAPI is a multi-threaded mode, which is much faster. But there is a problem. Many commonly used PHP extensions are developed based on the multi-process thinking of Linux/Unix. When these extensions are run in ISAPI mode, they will go wrong and bring down IIS. Therefore, CGI mode is the safest way to run PHP under IIS, but CGI mode requires reloading and unloading the entire PHP environment for each HTTP request, and its consumption is huge.

In order to take into account the efficiency and security of PHP under IIS, Microsoft provides the FastCGI solution. FastCGI allows PHP processes to be reused instead of reopening a process for each new request. At the same time, FastCGI can also allow several processes to execute at the same time. This not only solves the problem of excessive consumption of CGI process mode, but also takes advantage of the fact that CGI process mode does not have thread safety issues.

Therefore, if you use ISAPI to run PHP, you must use the Thread Safe (thread safe) version; and if you use FastCGI mode to run PHP, there is no need to use thread safety check, use None Thread Safe (NTS, non Thread-safe) version can better improve efficiency.

Architecture x86: It means that the PHP architecture is 32-bit (For a brief introduction to some php architecture and kernel, please see the portal here )

After preparing the above work, let us download the redis extension. Because my PHP version is vc11 TS, so I downloaded the thread-safe version

Download back to php_igbinary-1.2.1-5.5-ts-vc11-x86.zip extension

Download back to php_redis-2.2.5-5.5-ts-vc11-x86.zip extension

Download redis-2.4.5-win32-win64.zip (The installation package in this portal has two versions after decompression. Just use the version with the same number of system digits. Note that it is System number of bits, notphp architecture number of bits)

The preparations are now complete! Next enter the installation steps

The first step is to unzip the Redis installation package to any folder. Just treat it as a software. (I installed it on the F drive here)

Open the cmd interface and type the command

Do not close this window, now this cmd window has become the redis server

Then open a dos window and type the command

Command analysis:

redis-cli.exe -h 127.0.0.1 -p 6379

redis-cli.exe starts redis client

　-h host address

　-p redis port number (default 6379)

Test it next

Command parsing

set key name value

get key name will output the value corresponding to the key name

Well, redis is installed, let’s install the php redis extension

Unzip the two files we downloaded from the beginning, and copy the .dll file inside to the ext folder under the php startup program

Mine is here I use the integrated wamp environment Correspond to your own php installation location, just put it in this extension directory

After placing it, open php.ini and add it (any location, I put it at the end of the document)

;php_redis
extension=php_igbinary.dll
extension=php_redis.dll

Restart all wamp services and print phpinfo again

Seeing this means that the redis extension has been mounted successfully!

Hope this document can help you!
