[root@ecs-s6-large-2-linux-20201108111405 ~]# git clone https://github.com/arnaud-lb/php-rdkafka.git
2、执行phpize生成configure文件

phpize

3、编译安装

[root@ecs-s6-large-2-linux-20201108111405 php-rdkafka]# ./configure --with-php-config=/www/server/php/72/bin/php-config

结果编译安装报错

解决办法如下

git下载librdkafka https://github.com/edenhill/librdkafka.git

执行编译安装

./configure

make&&make install

执行完成后返回php-rdkafka目录再次执行一遍./configure make&&make install

编辑php配置文件php.ini

extension=rdkafka.so

完成  搞定！
