[Err] 1194 – Table is marked as crashed and should be repaired

正在写代码，突然服务器超级卡，点开任务管理器发现CPU一直百分百，切换到进程，将CPU栏从高到低排列，瞬间发现mysqld.exe 这个进程CPU占用超高。

分析日志

启用mysql通用查询日志

set global general_log=on;

设置通用日志输出为表格形式

set global log_output='TABLE';

然后打开mysql数据裤查看 general_log 表

SELECT * FROM 'general_log' LIMIT 0, 200

发现最近mysql查询全部围绕的是 wp_it_options 这个表，查询的语句也是一直重复这几条语句

SELECT option_name, option_value FROM wp_it_options
SELECT option_name, option_value FROM wp_it_options WHERE autoload = 'yes'

手动执行该语句报错：

[SQL]SELECT option_name, option_value FROM wp_it_options WHERE autoload = 'yes'

[Err] 1194 - Table 'wp_it_options' is marked as crashed and should be repaired

wp_it_options 表标记有问题，需要修复。 我记得前几天查日志的时候，也看到过这个错误，当时我还用这种快速解决的方式解决过：

myisamchk -c -r ../data/lrwa/wp_it_options.MYI

不知道为什么又出现了。那么再一次解决吧。

修复mysql 1194 错误

解决 [Err] 1194 - Table is marked as crashed and should be repaired 问题可以用  mysqlcheck.exe 工具，先用 mysqlcheck.exe 查看一下吧。

嗯，只有 wp_it_options 表有问题，我们添加 –auto-repair 参数自动修复试试，先备份哦。

提示OK，我们在执行上面日志中记录的那条语句，发现已经可以正常查询 这个时候CPU也已经不再过高了，虽然还有些不稳定，但是不稳定问题并不在是因为mysql了。 最后，附上两个 general_log 命令：

set global general_log=off; //关闭mysql通用日志
truncate table general_log;  //清空general_log日志

关于懒人网安

懒人网安这个站点是我很久以前建的，最开始是博客，后来改成了工作室的性质。 因为我爱折腾，又没有备份的习惯，导致该站数据裤和代码许多地方都存在问题，因此于 2016年8月 建立了本博客，弃用了 懒人网安，已经停止更新和维护。 其实我很为该站的安全担忧，因为已经没有在搭理它了，之所以还留着，无非就是该站还有点流量，权限我已经尽量限制，先暂时留着，等到了哪天必须舍弃的时候，在删掉做个301就好。
