hongblue

　　系统环境:linux

　　先查看mysql是否安装了innodb插件

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

　　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

[iyunv@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)

　　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
　　
　　重启数据库
　　

/etc/init.d/mysqld restart
　　
　　到此完成.
