Mysql達到最大限制

Question

我每隔15分鐘運行一次cron作業，它會提取feed並將它們存儲到數據庫，從新的新數據庫中可以正常工作，並且我可以看到每隔15分鐘我的數據庫就會被填充。

但後說兩個星期數據庫似乎達到其最大極限，不會再存儲數據以及我可不能拉下它通過我的代碼點火器的應用程序，什麼是處理大量數據的最佳方式？

我正在使用專用服務器，並且對mysql以前的高數據需求知之甚少。這裏是我的/etc/my.cnf中的設置

[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 

什麼是最大明智的設置，我可以設置，使我的SQL過去很長一段時間，是的，我不知道很多關於這個真的很需要保持這個運行，因爲我不能清除數據，然後再次開始填充數據庫，我需要它來保存。

謝謝你是進步;）

哇，我不知道什麼最關這意味着不好看壽

對不起這個問題越來越愚蠢長，但只是試圖更新與我需要下面是我的codeignitor插入我應該如何做到這一點正確連接和斷開連接

<?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']; 

     } 

    } 


} 

感謝您的幫助大家

您如何連接數據庫？對於您所描述的過程，您應該每次連接和斷開連接。
