今天,在用war包方式安装jira5.0时,报出Unknown table engine 'InnoDB'的错误,网上查了不少资料,解决方法都是说开启mysql的innodb,下面是官方说明:
- Check to see whether you have InnoDB support enabled:
mysql> show variables like
'have_innodb'
;
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| have_innodb | YES |
+---------------+-------+
1
row in set (
0.00
sec)
- If the value above is DISABLED, then you would need to enable InnoDB.
- Open up MySQL's configuration file. On various platforms, the configuration file may differ in file name and location:
- Windows:
$MYSQL_INSTALL_DIRECTORY/my.ini
- Linux/Unix:
/etc/mysql/my.cnf
- Windows:
- If the parameter
skip-innodb
is uncommented/exists, then just comment it out:# skip-innodb
- Shutdown MySQL server, delete/rename the MySQL logs to refresh the entire server's logging, and restart MySQL server:
- Linux:
~$: /etc/init.d/mysql stop
~$: rm /var/lib/mysql/ib_logfile*
~$: /etc/init.d/mysql start
- Windows:
Go to$MYSQL_INSTALL_DIRECTORY/data
and either delete/move the log files with the prefixib_logfile
.
- Linux:
按上面方法,但是发现我的my.cnf文件当中,根本就没有关于skip-innodb的这一行,也没有类似于ib_logfile的日志文件,无法解决,纠结。。
终于,在努力折腾了几个小时之后,找到了正解。
原来是新版的mysql不带innodb引擎。
在configure的时候要加上--with-plugins=innobase这个参数
验证是否装好innodb
安装好后登录mysql
执行
show plugin
如果有Innodb这条信息就表示安装好了。
如果没有安装成功或者是在已经安装好mysql的情况下,只要执行下面语句再安装一次就OK。
install plugin innodb soname ‘ha_innodb.so’ ;
终于搞定。
