php and message queues implemented redis

 php + Redis message queue is a time of between php + mysql insufficient performance intermediate processing scheme. By the middle of the process to ensure data availability and accuracy. The server requests for large moment, the pressure is large database. As a result of concurrent oversold large, resulting in a large amount of concurrent data duplication.

        Process: php accept requests and data -> php redis write data queue (enqueue) -> shell timing of writing data read queue call php MySQL (dequeued)

        Implementation code:

Into the team: inqueue.php

php

1. <?php
2. $redis = new redis();
3. $redis->connect('127.0.0.1',6379);
4. $redis -> select('1');
5. $redis->auth('');
6.  
7. Data $  = [ A , B , C , D , E , F , G , H ]; // this may be get or post requests over the data  
8. $data = json_encode($data);
9. $in = $redis->rpush('queue',$data);
10. if($in){
11.     echo  "into team success" ;
12. }

A team: outqueue.php

php

1. #!/usr/bin/php
2. <?php
3. $redis = new redis();
4. $redis->connect('127.0.0.1',6379);
5. $redis -> select('1');
6. $redis->auth('');
7.  
8. $value = $redis->lpop('queue');
9. $value = json_decode($value,true);

shell process.sh: regular script calls outqueue.php

php

1. # Be called once per minute
2. * * * * * /usr/local/nginx/html/process.sh

php

1. #!/bin/bash
2. #file_name : process.sh
3. #author: zuoping
4. php /usr/local/nginx/html/outqueue.php

* If you call every minute frequency is not enough, you can call the script executed multiple times, such as:

php

1. #!/bin/bash
2. #file_name : process.sh
3. #author: zuoping
4. php /usr/local/nginx/html/outqueue.php
5. php /usr/local/nginx/html/outqueue.php
6. php /usr/local/nginx/html/outqueue.php
7. php /usr/local/nginx/html/outqueue.php
8. php /usr/local/nginx/html/outqueue.php
9. php /usr/local/nginx/html/outqueue.php
10. php /usr/local/nginx/html/outqueue.php
11. php /usr/local/nginx/html/outqueue.php
12. php /usr/local/nginx/html/outqueue.php
13. php /usr/local/nginx/html/outqueue.php
14. php /usr/local/nginx/html/outqueue.php
15. # This one minute call many times.

View current data in the queue:

php

1. <?php
2. $redis = new redis();
3. $redis->connect('127.0.0.1',6379);
4. $redis -> select('1');
5. $redis->auth('');
6.  
7. $list = $redis->lrange('queue',0,-1);
8. var_dump ( $ list );
