错误提示找不到mysql-bin.000002文件,但检查该文件是存在的：
MYSQL实例
[root@host1 mysql]# ls mysql-bin.000002
mysql-bin.000002
怀疑可能是权限问题,于时查看：
MYSQL实例
[root@host1 mysql]# ls -al 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：
MYSQL实例
chown -R mysql:mysql mysql-bin.000002
mysql无法启动的问题顺利解决了.MYSQL实例
