备份ib_logfile1，ib_logfile0后删除掉
重启mysql
还是报Timeout error occurred trying to start MySQL Daemon；
df -h，居然使用100%，删除日志文件等等，查看还是100%，
执行/usr/bin/mysql_install_db

日志满了
稀里糊涂的，还没搞醒合。
解决了，数据文件保留在，不过数据库用户密码要重新设置。
网上看到一个办法：
解决方法： 以RPM 包安装版本
执行文件路径： /USR/BIN/MYSQL (以MY 开头的 所有执行文件)
安装目录是： /usr/share/mysql
数据库存储路径： /usr/lib/mysql
首先查看 硬盘空间 是否已满
[root@hot~]# df （查看硬盘 空间使用情况）
修复日志数据
myisamchk -f /var/lib/mysql/system_db/*.MYI
mysql 服务可以启动了
修复表
先登录 MYSQL
1、/USR/BIN/MYSQL -U ROOT -P
2、showdatabases；
3、repiar table 加表名称
更改 MAX_JOIN_SIZE
mysql> select @@max_join_size;
+-----------------+
| @@max_join_size |
