工做中，难免会遇到前辈已经编译安装过的mysql，突然发现mysql不支持innodb的存储引擎的问题，如今来看一下吧
mysql

1、先看mysql是否支持innodb存储引擎sql

mysql> show variables like 'ha%';bash

+----------------------+----------+ide

| Variable_name | Value |spa

+----------------------+----------+插件

| have_compress | YES |code

| have_crypt | YES |orm

| have_csv | YES |ssl

| have_dynamic_loading | YES |ci

| have_geometry | YES |

| have_innodb | DISABLED |

| have_ndbcluster | NO |

| have_openssl | DISABLED |

| have_partitioning | YES |

| have_profiling | YES |

| have_query_cache | YES |

| have_rtree_keys | YES |

| have_ssl | DISABLED |

| have_symlink | YES |

+----------------------+----------+

14 rows in set (0.00 sec)

have_innodb：值为DISABLED，表示未启用，值为no，表示不支持innodb存储引擎

mysql> show plugins;

+-----------------------+----------+----------------+---------+---------+

+-----------------------+----------+----------------+---------+---------+

+-----------------------+----------+----------------+---------+---------+

如今的mysql的确不支持innodb存储引擎

2.查看是否支持动态加载插件

mysql> show variables like 'have_dynamic%';

+----------------------+-------+

| Variable_name | Value |

+----------------------+-------+

| have_dynamic_loading | YES |

+----------------------+-------+

1 row in set (0.00 sec)

have_dynamic_loading：值为yes，表示动态加载mysql的插件

当使用源码编译安装时不能使用-with-mysqld-ldflags=all-static选项

3.放入插件文件，找到mysql存放插件的路径

mysql> show variables like 'plugin_dir';

+---------------+------------------------------+

| Variable_name | Value |

+---------------+------------------------------+

| plugin_dir | /usr/local/mysql/lib/plugin/ |

+---------------+------------------------------+

 
  #在该目录中查看是否已有ha_innodb.so和ha_innodb_plugin.so两个文件 
 

 
  [root@zhu2 mysql-5.1.39] 
  # ll /usr/local/mysql/lib/plugin/ha_innodb.so

 
  lrwxrwxrwx 1 mysql mysql 18 08-22 02:55  
  /opt/mysql/lib/mysql/plugin/ha_innodb 
  .so -> ha_innodb.so.0.0.0 
 

 
  [root@zhu2 mysql-5.1.39] 
  # ll /usr/local/mysql/lib/plugin/ha_innodb_plugin.so

 
  lrwxrwxrwx 1 mysql mysql 25 08-22 02:55  
  /opt/mysql/lib/mysql/plugin/ha_innodb_plugin 
  .so -> ha_innodb_plugin.so.0.0.0 
 

 
  #若没有能够去网上下载与所安装mysql对应的版本，或者直接去mysql源码包中storage/innobase/.libs/ha_innodb.so 
 

 
  storage 
  /innodb_plugin/ 
  .libs 
  /ha_innodb_plugin 
  .so 复制到mysql的plugin目录中 
 

4.添加动态安装加载

 
  mysql>  INSTALL PLUGIN InnoDB SONAME  
  'ha_innodb.so' 
  ; 
 

 
  Query OK, 0 rows affected (0.61 sec) 
 

5.看如今是否支持innodb

 
  mysql> show plugins; 
 

 
  +------------+--------+----------------+--------------+---------+ 
 

 
  | Name       | Status | Type           | Library      | License | 
 

 
  +------------+--------+----------------+--------------+---------+ 
 

 
  | binlog     | ACTIVE | STORAGE ENGINE | NULL         | GPL     | 
 

 
  | CSV        | ACTIVE | STORAGE ENGINE | NULL         | GPL     | 
 

 
  | MEMORY     | ACTIVE | STORAGE ENGINE | NULL         | GPL     | 
 

 
  | MyISAM     | ACTIVE | STORAGE ENGINE | NULL         | GPL     | 
 

 
  | MRG_MYISAM | ACTIVE | STORAGE ENGINE | NULL         | GPL     | 
 

 
  | InnoDB     | ACTIVE | STORAGE ENGINE | ha_innodb.so | GPL     | 
 

 
  +------------+--------+----------------+--------------+---------+ 
 

 
  6 rows  
  in 
  set 
  (0.01 sec) 
 

 
  mysql> show engines; 
 

 
  +------------+---------+------------------------------------------------------------+--------------+------+------------+ 
 

 
  | Engine     | Support | Comment                                                    | Transactions | XA   | Savepoints | 
 

 
  +------------+---------+------------------------------------------------------------+--------------+------+------------+ 
 

 
  | CSV        | YES     | CSV storage engine                                         | NO           | NO   | NO         | 
 

 
  | InnoDB     | YES     | Supports transactions, row-level locking, and foreign keys | YES          | YES  | YES        | 
 

 
  | MEMORY     | YES     | Hash based, stored  
  in 
  memory, useful  
  for 
  temporary tables  | NO           | NO   | NO         | 
 

 
  | MyISAM     | DEFAULT | Default engine as of MySQL 3.23 with great performance     | NO           | NO   | NO         | 
 

 
  | MRG_MYISAM | YES     | Collection of identical MyISAM tables                      | NO           | NO   | NO         | 
 

 
  +------------+---------+------------------------------------------------------------+--------------+------+------------+ 
 

 
  5 rows  
  in 
  set 
  (0.01 sec) 
 

2、追加编译

1.删除innodb支持，应查看

 
         mysql> UNINSTALL PLUGIN innodb; 
        
         Query OK, 0 rows affected (0.52 sec) 
        
         mysql> show engines; 
        
         +------------+---------+-----------------------------------------------------------+--------------+------+------------+ 
        
         | Engine     | Support | Comment                                                   | Transactions | XA   | Savepoints | 
        
         +------------+---------+-----------------------------------------------------------+--------------+------+------------+ 
        
         | CSV        | YES     | CSV storage engine                                        | NO           | NO   | NO         | 
        
         | MRG_MYISAM | YES     | Collection of identical MyISAM tables                     | NO           | NO   | NO         | 
        
         | MEMORY     | YES     | Hash based, stored  
         in 
         memory, useful  
         for 
         temporary tables | NO           | NO   | NO         | 
        
         | MyISAM     | DEFAULT | Default engine as of MySQL 3.23 with great performance    | NO           | NO   | NO         | 
        
         +------------+---------+-----------------------------------------------------------+--------------+------+------------+ 
        
         4 rows  
         in 
         set 
         (0.00 sec)

2.从新编译

注：注意mysql的编译安装方式，

2.看mysql不支持或者未启用innodb存储引擎
