错误提示找不到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

怀疑可能是权限问题,于时查看:
 

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

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

mysql无法启动的问题顺利解决了。
