Manually enabling Swoole via php.ini

On most systems Swoole can be enabled by directly editing your

configuration file, you will want to add

to the end of the file and then Swoole should be enabled.

Enabling Swoole via phpenmod

Some Linux distributions like Debian or Ubuntu use the PHP

to load PHP extensions, in this case you can use

to enable Swoole.

一般系统 都可以通过添加扩展到php.ini的方式添加swoole支持，但我用的debian10+php7.4不支持，报如下错
 

PHP Warning: PHP Startup: Unable to load dynamic library 'swoole' (tried: /usr/lib/php/20190902/swoole (/usr/lib/php/20190902/swoole: cannot open shared object file: No such file or directory), /usr/lib/php/20190902/swoole.so (/usr/lib/php/20190902/swoole.so: undefined symbol: php_json_exception_ce)) in Unknown on line 0

只能通过

#!/bin/bash

# Create a Swoole extension PHP ini file, letting PHP know which modules to load
$ sudo bash -c "cat > /etc/php/<PHP_VERSION>/mods-available/swoole.ini << EOF
; Configuration for Swoole
; priority=25
extension=swoole
EOF"

# Enable the Swoole PHP extension only on CLI mode
$ sudo phpenmod -s cli swoole

# Optional: Enable Swoole for specific version of PHP CLI
$ sudo phpenmod -s cli -v 7.4 swoole

# Check if the Swoole extension has been enabled
$ php -m | grep swoole

You can also disable Swoole using

if you need to (this is not uninstalling, just turning Swoole off):

#!/bin/bash

# Turn off Swoole for CLI or a specific PHP install
sudo phpdismod -s cli swoole
sudo phpdismod -s cli -v 7.4 swoole
