分析一下mysql的状态

[朱丽叶与驴斗殴]

网站放在是VPS上， 1G内存，VPS上主要放了二次开发过的DISCUZ X2.0的程序，每次运行时间都达到了0.5秒左右，数据库查询在10次左右，但是本地测试的时候运行时间很短，数据库查询也就5次左右。初步估计应该是数据库查询或者数据库参数配置不正确的问题，下面是用phpmyadmin查看的数据，牛人分析一下什么情况，谢谢。

====================分割线=============================
MySQL 服务器已经运行了 16 天 1 小时，29 分 37 秒







下面几个变量的值是被phpmyadmin用红色标记出来的，这里我把变量名用红色标出来是为了看得直观一点
Handler_read_rnd 3,561 k
Handler_read_rnd_next 307 M
Qcache_lowmem_prunes 2,856 k
Created_tmp_disk_tables 5,324
Key_reads 2,590 k
Select_full_join 32 k
Sort_merge_passes 7,132
Opened_tables 105 k
Table_locks_waited 46 k

是不是搜索引擎的爬网蜘蛛弄的。

[朱丽叶与驴斗殴]

自己来顶一顶

[jinguanding]

给你推荐一个非常实用的自动采集脚本：MySQL数据库运行状态数据采集的脚本

而你这个是整体的平均值，这个脚本只要你自己在crontab设置时间间隔，就自动跑起来，建议5分钟一次的价格...文章中有详细介绍

不太清楚。
昨天重启了MSYQL，到现在运行20个小时，数据库数据量流量就4G了，整个数据库也就两三百兆，而且网站人很少，我不知道这是个什么概念，是不是很正常
