Mysql 集群 7.2.2 忽略设置和 TABLE IS FULL 错误答案

【问题描述】：

这是我的my.cnf 设置

[mysqld]
ndbcluster
#engine_condition_pushdown=0
optimizer_switch=engine_condition_pushdown=off

# IP address of the cluster management node
ndb-connectstring=127.0.0.1

[mysql_cluster]
# IP address of the cluster management node
ndb-connectstring=127.0.0.1


[ndbd default]
NoOfReplicas= 2
MaxNoOfConcurrentOperations= 10000
DataMemory= 320M
IndexMemory= 96M
TimeBetweenWatchDogCheck= 30000
DataDir= /usr/local/mysql-cluster-gpl-7.2.2-osx10.6-x86_64/mysql-cluster
MaxNoOfOrderedIndexes= 512



[MYSQLD DEFAULT]

[NDB_MGMD DEFAULT]

[TCP DEFAULT]

# Section for the cluster management node
[NDB_MGMD]
# IP address of the management node (this system)
id=1
HostName=127.0.0.1


# Section for the storage nodes
[NDBD]
# IP address of the first storage node
id=2
HostName=127.0.0.1
DataDir= /usr/local/mysql-cluster-gpl-7.2.2-osx10.6-x86_64/mysql-cluster


[NDBD]
# IP address of the second storage node
id=3
HostName=127.0.0.1
DataDir= /usr/local/mysql-cluster-gpl-7.2.2-osx10.6-x86_64/mysql-cluster2

# one [MYSQLD] per storage node
[MYSQLD]
[MYSQLD]

我将数据内存设置为 320M，当我运行脚本来填充表时，它会因错误“表 blabla 已满”而停止。我尝试使用-f 选项和配置文件路径运行ndb_mgmd。我将此文件复制到名为 config.ini 的 mysql-cluster 文件夹中，但没有结果。

我明白了：

ndb_mgm> ALL REPORT MEMORYUSAGE
Node 2: Data usage is 100%(2560 32K pages of total 2560)
Node 2: Index usage is 74%(1741 8K pages of total 2336)
Node 3: Data usage is 100%(2560 32K pages of total 2560)
Node 3: Index usage is 74%(1741 8K pages of total 2336)

2560*32K=80M。 80M 相当于默认的 mysql 集群设置。

【问题讨论】：

您是否使用 --initial 或 --reload 选项重新启动 ndb_mgmd 以从配置文件中重新获取配置？如果没有，配置文件中的更改将被忽略，配置将从 config-dir 中的二进制存储中获取。
如果所有设置都在一个文件中，则读取设置时出错。 mysqld 启动正常。但是 ndb_mgmd 记录有关忽略设置文件的错误，因为 mysqld 的设置他无法解析，并停止加载文件。

【解决方案1】：

我解决了我的问题。我需要将此配置划分为两个配置文件，一个用于 mysql 服务器并将其放在 data/my.cnf 中：

[mysqld]
ndbcluster
#engine_condition_pushdown=0
optimizer_switch=engine_condition_pushdown=off

# IP address of the cluster management node
ndb-connectstring=127.0.0.1

[mysql_cluster]
# IP address of the cluster management node
ndb-connectstring=127.0.0.1

/mysql_cluster/config.ini 文件夹中集群包的第二个文件：

[ndbd default]
NoOfReplicas= 2
MaxNoOfConcurrentOperations= 10000
DataMemory= 320M
IndexMemory= 96M
TimeBetweenWatchDogCheck= 30000
DataDir= /usr/local/mysql-cluster-gpl-7.2.2-osx10.6-x86_64/mysql-cluster
MaxNoOfOrderedIndexes= 512



[MYSQLD DEFAULT]

[NDB_MGMD DEFAULT]

[TCP DEFAULT]

# Section for the cluster management node
[NDB_MGMD]
# IP address of the management node (this system)
id=1
HostName=127.0.0.1


# Section for the storage nodes
[NDBD]
# IP address of the first storage node
id=2
HostName=127.0.0.1
DataDir= /usr/local/mysql-cluster-gpl-7.2.2-osx10.6-x86_64/mysql-cluster


[NDBD]
# IP address of the second storage node
id=3
HostName=127.0.0.1
DataDir= /usr/local/mysql-cluster-gpl-7.2.2-osx10.6-x86_64/mysql-cluster2
