由错误信息可知，是由于找不到mysql-bin.000002文件，但检查该文件是存在的。
复制代码 代码示例:
[root@host1 mysql]# ls mysql-bin.000002
mysql-bin.000002
mysql-bin.000002
可能是权限的问题，再次检查：
复制代码 代码示例:
[root@host1 mysql]# ls -al mysql-bin.000002
-rw-rw---- 1 root root 733525 12-27 14:10 mysql-bin.000002
-rw-rw---- 1 root root 733525 12-27 14:10 mysql-bin.000002
文件属主变成了root，将该文件修改为mysql：
复制代码 代码示例:
chown -R mysql:mysql mysql-bin.000002
如此，mysql便可以正常启动了，问题解决了。
