安装MySQL后如何添加联合引擎

Question

我有mysql 5.5.18
并在展示引擎上：

show engines;
+--------------------+---------+------------------------------------------------------------+--------------+------+------------+
| Engine             | Support | Comment                                                    | Transactions | XA   | Savepoints |
+--------------------+---------+------------------------------------------------------------+--------------+------+------------+
| InnoDB             | DEFAULT | Supports transactions, row-level locking, and foreign keys | YES          | YES  | YES        |
| PERFORMANCE_SCHEMA | YES     | Performance Schema                                         | NO           | NO   | NO         |
| MRG_MYISAM         | YES     | Collection of identical MyISAM tables                      | NO           | NO   | NO         |
| CSV                | YES     | CSV storage engine                                         | NO           | NO   | NO         |
| MyISAM             | YES     | MyISAM storage engine                                      | NO           | NO   | NO         |
| MEMORY             | YES     | Hash based, stored in memory, useful for temporary tables  | NO           | NO   | NO         |
+--------------------+---------+------------------------------------------------------------+--------------+------+------------+

如您所见，联合引擎不是其中之一。我需要启用它！为什么列表中缺少黑洞，联合和档案引擎的原因有什么想法吗？我该怎么 添加/启用 他们？
编辑
我有Ubuntu 11.10并从PPA安装MySQL ...我已将以下内容添加到/etc/apt/sources.list.list

deb http://ppa.launchpad.net/nathan-renniewaldock/ppa/ubuntu oneiric main
deb-src http://ppa.launchpad.net/nathan-renniewaldock/ppa/ubuntu oneiric main

谢谢你的帮助

Answer 1

我设法找到了一个解决方案...
已经有一个插件
/usr/lib/mysql/plugin/ha_federated.so
我只是登录MySQL作为root并运行以下查询 mysql>install plugin federated soname 'ha_federated.so';
然后我添加了联合到我的.cnf并重新启动mysql

Answer 2

如果默认安装/二进制安装

我认为 BLACKHOLE , ARCHIVE 安装MySQL Server时默认安装并启用。

但是 FEDERATED 默认情况下不启用。

您可以手动启用它已编辑您的my.cnf file.edit my.cnf，在[mySQLD]部分中，添加行：

federated

现在重新启动MySQL Server。

用于添加 Archive 转到链接 http://timanovsky.wordpress.com/2010/10/09/enabling-Archive-Archive-storage-engine-engine-in-ius-mysql-5-1/

如果您已经从源头安装，那么您应该这样做：

对于黑洞： 调用配置 --with-blackhole-storage-engine 选项。

对于拱门： 调用配置 --with-archive-storage-engine 选项

用于联邦： 调用配置 --with-federated-storage-engine 选项

Answer 3

我知道这个帖子有点古老，但是似乎许多人在联合发动机上有问题。

当通过百胜安装MySQL二进制文件时，您已经有了HA（高可用性）插件。您只需要将插件加载到MySQL CLI中即可。

这是基本过程：

如果尚未启动MySQLD。确保“联合”此时不在/etc/my.cnf中。

例如：目前， /etc/my.cnf将从标准百胜安装中看起来像这样。

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

使用root（或具有足够特权的另一个帐户）登录MySQL CLI。

类型： show engines;

此时，您应该看不到联合引擎：

mysql> show engines;
+------------+---------+------------------------------------------------------------+--------------+------+------------+
| Engine     | Support | Comment                                                    | Transactions | XA   | Savepoints |
+------------+---------+------------------------------------------------------------+--------------+------+------------+
| MRG_MYISAM | YES     | Collection of identical MyISAM tables                      | NO           | NO   | NO         |
| CSV        | YES     | CSV storage engine                                         | NO           | NO   | NO         |
| MyISAM     | DEFAULT | Default engine as of MySQL 3.23 with great performance     | 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         |
+------------+---------+------------------------------------------------------------+--------------+------+------------+
5 rows in set (0.00 sec)

要启用联邦发动机，请键入以下内容：

install plugin federated soname 'ha_federated.so'

现在，当您“显示引擎”时，您会看到联合发动机，但关闭...

看起来像这样：

mysql> show engines;
+------------+---------+------------------------------------------------------------+--------------+------+------------+
| Engine     | Support | Comment                                                    | Transactions | XA   | Savepoints |
+------------+---------+------------------------------------------------------------+--------------+------+------------+
| FEDERATED  | NO      | Federated MySQL storage engine                             | NULL         | NULL | NULL       |
| CSV        | YES     | CSV storage engine                                         | NO           | NO   | NO         |
| MyISAM     | DEFAULT | Default engine as of MySQL 3.23 with great performance     | 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         |
| MRG_MYISAM | YES     | Collection of identical MyISAM tables                      | NO           | NO   | NO         |
+------------+---------+------------------------------------------------------------+--------------+------+------------+
6 rows in set (0.00 sec)

现在，您可以安全地将“联合”行添加到/etc/my.cnf文件中：

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
federated

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

重新启动mysqld（Service MySQLD重新启动等...）

重新启动后，回到MySQL CLI。

类型 show engines;

现在，您应该看到可用的联合引擎，并支持为“是”。

mysql> show engines;
+------------+---------+------------------------------------------------------------+--------------+------+------------+
| Engine     | Support | Comment                                                    | Transactions | XA   | Savepoints |
+------------+---------+------------------------------------------------------------+--------------+------+------------+
| FEDERATED  | YES     | Federated MySQL storage engine                             | NO           | NO   | NO         |
| CSV        | YES     | CSV storage engine                                         | NO           | NO   | NO         |
| MyISAM     | DEFAULT | Default engine as of MySQL 3.23 with great performance     | 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         |
| MRG_MYISAM | YES     | Collection of identical MyISAM tables                      | NO           | NO   | NO         |
+------------+---------+------------------------------------------------------------+--------------+------+------------+
6 rows in set (0.00 sec)

而且您已经完成了...前进并创建联邦表...

Answer 4

在ML上，我需要做的MySQL 5.5（当前）是：

• 从/usr/local/mysql/support-files/to/etc/my.cnf复制现有文件之一
• 在[mySQLD]部分（不是my.cnf文件的末尾）添加“联合”（无引号）
• 重新启动mysql

对于那些想要一种自动化方式来声明表的人来说，这也可能很有用： http://sylnsr.blogspot.com/2012/11/auto-constructing-ddl-for-mysql.html
