phpredis errors Class Redis not found in Linux

Question

I met a weied problem when installing phpredis by

cd phpredis && ./configure && make && make install

after that, I add

extension=redis.so

into php.ini.

I can get an OK by running

php -r "if (new Redis() == true){ echo \"\r\n OK \r\n\"; }"

BUT when running http:127.0.0.1, nginx throw a error " Fatal error: Class 'Redis' not found in index.php"

<?php>
    $client = new Redis();
<?>

I guess this may be some problems related with environment...

Thanks for any advice!

The command line probably does not use the same php.ini file than the web server. Use phpinfo(); to know which configuration file is loaded in both cases and then declare your extension in the ini file used by your web server.

Sorry, I was drunk, with $r = new \Redis(); (with a backslash) it works. Probably looking the another error line with setOption(Redis::OPT_PREFIX... – François Breton Nov 18 '16 at 02:42
I fixed uncommenting in /etc/php/conf.d/igbinary.ini and /etc/php/conf.d/redis.ini – insign May 31 '20 at 22:54

I had this issue minutes ago, and I solved it restarting the server, this way the server refresh *.ini files

If you're using composer and get the error "Class Redis not found" try put a backslash before the name class. Like this:

<?php
    $client = new \Redis();
<?
