hu60.cn数据库配置已优化，表已从MyISAM存储引擎转为InnoDB存储引擎，期待性能可以提升

帖子的点击量是我用ab命令刷的。

[2020-07-08 22:30] hu60.cn数据库配置已优化，表已从MyISAM存储引擎转为InnoDB存储引擎，期待性能可以有所提升。

@000：@老虎会游泳，感觉对虎林来说 换存储引擎应该变化不大 (联合)索引弄好点就差不多了

@老虎会游泳：@000，不一定。并发访问帖子的问题在于每次访问都要给帖子的访问量+1，MyISAM就会一直锁定表。InnoDB的并发写入性能应该会好很多，可以只锁定行，而不是整个表。这样，只有被CC的那个帖子打不开而已，不会影响我们查看其他帖子。

ab的压测结果明显改善了，以前ab -n10000 -c1000 https://hu60.cn/q.php/bbs.topic.94721.html10分钟根本完不成，而且只要我一执行，谁也打不开网站。现在我执行过程中其他帖子可以打开了，而且这个命令5秒就执行完了。

其中Failed requests: 9385都是防CC模块的功劳，刷新不规范，虎友两行泪

[2020-07-08 21:45] 正在折腾hu60.cn的数据库，hu60.cn正在反向代理到hu60.net，打开速度会明显变慢

[2020-07-08 21:30] 数据库裂开预警：我在编译新版本的mysql，很快就要替换了。届时hu60.cn和m.hu60.cn又可能会发生各种状况，请做好心理准备

[2020-07-08 15:00] hu60.cn和m.hu60.cn挂了百度云加速，现在应该可以访问了。

[2020-07-07] 今天惊讶的发现apache2的a2modphp只能开256个工作进程，太少了，大并发数时卡的不要不要的。
准备换成nginx+php-fpm试试。
