【转】源码安装Mysql，补装innodb引擎方法

首先确定，在mysql的'plugin_dir'下有ha_innodb_plugin.so和ha_innodb.so两个文件

查询'plugin_dir'的路径可以用以下命令

mysql> show variables like 'plugin_dir';
+---------------+-----------------------------------+
| Variable_name | Value                             |
+---------------+-----------------------------------+
| plugin_dir    | /usr/local/mysql/lib/mysql/plugin |
+---------------+-----------------------------------+
1 row in set (0.01 sec)

如果没有找到，在您的mysql编译目录里有下面的目录文件(内置的innodb和innodb_plugin)
storage/innobase/.libs/ha_innodb.so
storage/innodb_plugin/.libs/ha_innodb_plugin.so
您需要把它们(ha_innodb_plugin.so和ha_innodb.so)拷贝到mysql的plugin目录中(/usr/local/mysql/lib/mysql/plugin)
接下来就是在mysql命令行安装一下
