infobright系列二：数据迁移

安装之后把之前infobright的数据迁移到新安装的infobright上。

1：挺掉相关的服务

2：scp 把旧数据拷到新安装的infobright上

3：修改/etc/my-ib.cnf的数据目录

4：修改/etc/init.d/mysqld-ib 的相应数据目录

5：启动服务：

Option: KNLevel, value: 99.
Option: LicenseFile, value: <unknown>.
Option: LoaderMainHeapSize, value: 320.
Option: PushDown, value: 1.
Option: ServerMainHeapSize, value: 600.
Option: UseMySQLImportExportDefaults, value: 0.
Infobright instance configuration loaded.

150514 16:06:02 [ERROR] Can't start server: can't create PID file: Permission denied

　　

6：查看错误代码13的含义

权限问题。

修改数据目录的权限

chwod -R mysql.mysql infobright_data

重新启动服务即可
