[杂七杂八] Mysql安装innodb支持

系统环境:linux

数据库版本:mysql 5.1.47
需要要安装innodb类型支持
先查看mysql是否安装了innodb插件

[root@localhost bin]# ./mysql  mysql> show plugin;  +------------+--------+----------------+---------+---------+  | 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     |  +------------+--------+----------------+---------+---------+  

发现没有安装

mysql> install plugin innodb soname 'ha_innodb.so';  ERROR 1126 (HY000): Can't open shared library '/usr/local/mysql/lib/mysql/plugin/ha_innodb.so' (errno: 13 cannot restore segment prot after reloc: Permission denied)  

发现权限有问题

[root@localhost plugin]# chcon -t texrel_shlib_t /usr/local/mysql/lib/mysql/plugin/ha_innodb.so  

给权限再安装

mysql> install plugin innodb soname 'ha_innodb.so';  Query OK, 0 rows affected (0.36 sec)  mysql> show plugin;  +------------+--------+----------------+--------------+---------+  | 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, 1 warning (0.00 sec)  

安装成功

修改mysql配置文件/etc/my.cnf为以下内容.只为安装.就用默认值了.

# Uncomment the following if you are using InnoDB tables  innodb_data_home_dir = /usr/local/mysql/var/  innodb_data_file_path = ibdata1:10M:autoextend  innodb_log_group_home_dir = /usr/local/mysql/var/  # You can set .._buffer_pool_size up to 50 - 80 %  # of RAM but beware of setting memory usage too high  innodb_buffer_pool_size = 16M  innodb_additional_mem_pool_size = 2M  # Set .._log_file_size to 25 % of buffer pool size  innodb_log_file_size = 5M  innodb_log_buffer_size = 8M  innodb_flush_log_at_trx_commit = 1  innodb_lock_wait_timeout = 50
