We have deployed it in produtive enviroment, and I posted an article for it (but in Chinese), http://guweigang.com/blog/2013/11/18/mysql-binlog-in-realtime/. Hope it will help you.
A PHP-Client for mysql replication listener API.
You can use it to connect to a MYSQL server which produces BINLOG, and get BINLOG events in real-time, just like a Async-Trigger.
You know, we always need to use different components to do a good job, serve a good service. Just like we use MYSQL to storage all our data, use REDIS as a cache server, and use LUCENE as a search engine. The differences between MYSQL and other components will affect the sorting result, and therefore affect user experience, especially for time-sensitive service.
Our group use PHP to develop web projects. So if we have a PHP extension to do the data trigger job between different components, everything will be easy. This is what we do and why we do.
- MySQL Replication Listener Library (https://github.com/BullSoft/mysql-replication-listener)
- PHP 5.3.X
- MySQL 5.4 and lower
First, install mysql-replication-listener.
$ cmake . -DCMAKE_INSTALL_PREFIX=/home/work/mysql-replication
$ make && make install
Then change to php-binlog ext directory,
$ /home/work/local/php/bin/phpize
$ ./confingure --with-php-config=/home/work/local/php/bin/php-config --with-mysql-binlog=/home/work/mysql-replication
$ make
$ make install
注：Binlog为行格式
$link = binlog_connect("mysql://[email protected]:3306");
// binlog_set_position($link, 4);
while($event=binlog_wait_for_next_event($link)) {
// it will block here
switch($event['type_code']) {
case BINLOG_DELETE_ROWS_EVENT:
var_dump($event);
// do what u want ...
break;
case BINLOG_WRITE_ROWS_EVENT:
var_dump($event);
// do what u want ...
break;
case BINLOG_UPDATE_ROWS_EVENT:
var_dump($event);
// do what u want ...
break;
default:
// var_dump($event);
break;
}
