myisamchk: error: myisam_sort_buffer_size is too small解决办法

用myisamchk修复一个被损坏的表，结果显示如下错误：

root@10-10-74-251:/data/mysql_data/cmd5# myisamchk -r -f md5_core.MYI
- recovering (with sort) MyISAM-table 'md5_core.MYI'
Data records: 0
- Fixing index 1
myisamchk: error: myisam_sort_buffer_size is too small
MyISAM-table 'md5_core.MYI' is not fixed because of errors
Try fixing it by using the --safe-recover (-o), the --force (-f) option or by not using the --quick (-q) flag

myisamchk是没有myisam_sort_buffer_size的，只有sort_buffer_size，估计是sort_buffer_size不足，我的索引MYI文件很大，所以干脆设置--sort_buffer_size=160M。其他参数也设置一下吧，反正不超过内存大小就可以。执行如下命令进行sort_buffer_size设置并且修复表：
myisamchk -r -f md5_core.MYI --sort_buffer_size=160M --key_buffer_size=160M --read_buffer_size=20M --write_buffer_size=20M
