安装扩展
sudo pecl install seaslog
Build process completed successfully
Installing '/www/server/php/74/lib/php/extensions/no-debug-non-zts-20190902/seaslog.so'
install ok: channel://pecl.php.net/SeasLog-2.2.0
configuration option "php_ini" is not set to php.ini location
You should add "extension=seaslog.so" to php.ini
等待即可安装完成，然后自己配置到php.int里
sudo pecl install amqp
这里你会遇到问题，无非就是你还没安装rabbitmq的原因
先安装rabbitmq服务端，这时候你发现还是安装不上。
这时候你需要安装这个
sudo apt install librabbitmq-dev
安装完成后再执行 “sudo pecl install amqp”即可
