Mysql达到最大限制

Question

我每隔15分钟运行一次cron作业，它会提取feed并将它们存储到数据库，从新的新数据库中可以正常工作，并且我可以看到每隔15分钟我的数据库就会被填充。

但后说两个星期数据库似乎达到其最大极限，不会再存储数据以及我可不能拉下它通过我的代码点火器的应用程序，什么是处理大量数据的最佳方式？

我正在使用专用服务器，并且对mysql以前的高数据需求知之甚少。这里是我的/etc/my.cnf中的设置

[client] 
port   = 3306 
socket   = /var/lib/mysql/mysql.sock 


[mysqld_safe] 
log-error=/var/log/mysqld.log 
pid-file=/var/run/mysqld/mysqld.pid 

innodb_buffer_pool_size=2M 
innodb_additional_mem_pool_size=500K 
innodb_log_buffer_size=500K 
innodb_thread_concurrency=2 

[mysqld] 
local-infile=0 
datadir=/var/lib/mysql 
user=mysql 
symbolic-links=0 

max_connections = 100 
wait_timeout = 60 
query-cache-type = 1 
query-cache-size = 8M 
query_cache_limit = 2M 
thread_cache_size = 8 
tmp_table_size = 16M 
max_heap_table_size = 16M 
join_buffer_size = 1M 
table_open_cache = 64 

port   = 3306 
socket   = /var/lib/mysql/mysql.sock 
skip-external-locking 
key_buffer_size = 16M 
max_allowed_packet = 1M 
sort_buffer_size = 512K 
net_buffer_length = 8K 
read_buffer_size = 256K 
read_rnd_buffer_size = 512K 
myisam_sort_buffer_size = 8M 






innodb_buffer_pool_size = 16M 
innodb_additional_mem_pool_size = 2M 
innodb_log_buffer_size = 8M 

[mysqldump] 
quick 
max_allowed_packet = 16M 

[mysql] 
no-auto-rehash 

[myisamchk] 
key_buffer_size = 20M 
sort_buffer_size = 20M 
read_buffer = 2M 
write_buffer = 2M 

[mysqlhotcopy] 
interactive-timeout 

什么是最大明智的设置，我可以设置，使我的SQL过去很长一段时间，是的，我不知道很多关于这个真的很需要保持这个运行，因为我不能清除数据，然后再次开始填充数据库，我需要它来保存。

谢谢你是进步;）

哇，我不知道什么最关这意味着不好看寿

对不起这个问题越来越愚蠢长，但只是试图更新与我需要下面是我的codeignitor插入我应该如何做到这一点正确连接和断开连接

<?php if (! defined('BASEPATH')) exit('No direct script access allowed'); 


class Cron_model extends CI_Model { 

    function addResults($data){ 

     $this->db->select('*'); 
     $this->db->from('articles'); 
     $this->db->limit(5); 
     $this->db->like('title', $data['title']); 
     $this->db->order_by("date", "desc"); 
     $query=$this->db->get(); 

     if(!$query->num_rows()){ 

      $this->db->insert('articles', $data); 

      return $data['title']; 

     } 

    } 


} 

感谢您的帮助大家

您如何连接数据库？对于您所描述的过程，您应该每次连接和断开连接。
