Homestead 使用 pecl 安装 swoole 扩展

背景说明：

公司现有项目是基于laravle5.5开发的,随着业务的增长php及框架的短板也凸显出来，于是准备使用swoole扩展来解决并发问题，以下是记录安装swoole的过程。

环境说明及版本说明：

Homestead v10.7.0
swoole v4.4.17

php v7.3

1. 安装 swoole

[email protected]:~$ sudo pecl install swoole

遇到以下错误

WARNING: channel "pecl.php.net" has updated its protocols, use "pecl channel-update pecl.php.net" to update
Could not download from "https://pecl.php.net/get/mongodb-1.5.5.tgz", cannot download "pecl/mongodb" (Connection to `ssl://pecl.php.net:443' failed: ) Error: cannot download "pecl/mongodb" Download failed
install failed

解决方法：

[email protected]:~$ sudo pecl channel-update pecl.php.net

重新安装

[email protected]:~$ sudo pecl install swoole

安装的时候会有 yes/no 之类的选项，直接 enter 就可以了
出现如下文字说明已经安装成功：

Build process completed successfully
Installing '/usr/lib/php/20180731/swoole.so' Installing '/usr/include/php/20180731/ext/swoole/config.h' install ok: channel://pecl.php.net/swoole-4.4.17 configuration option "php_ini" is not set to php.ini location
You should add "extension=swoole.so" to php.ini

2. 开启扩展

查看当前 PHP 版本

[email protected]:~$ php -v PHP 7.3.7-2+ubuntu18.04.1+deb.sury.org+1 (cli) (built: Jul 25 2019 11:44:59) ( NTS ) Copyright (c) 1997-2018 The PHP Group

创建配置文件

[email protected]:~$ sudo touch /etc/php/7.3/mods-available/swoole.ini

写入以下内容
```
extension=swoole.so
```
添加软连接

[email protected]:/etc/php/7.3/cli/conf.d$ sudo ln -s /etc/php/7.3/mods-available/swoole.ini ./20-swoole.ini

重启 php-fpm
```
sudo service php7.3-fpm restart
```
查看扩展

[email protected]:/etc/php/7.3/cli/conf.d$ php --ri swoole
