我的MySQL群集测试设置遇到了麻烦：
我有两台运行Ubuntu和Docker的机器（使用多主机网络），每个节点（ndb_mgm，ndbd和mysqld）都通过Docker运行。设置如下：
计算机1 ：
机器2 ：
当我在一台机器上启动mysqld时，它连接到管理器并想要启动集群，但它无法创建表，整个NDB在mysqld实例上登录后新的开始：

最后一行显示，它无法创建表格：

如果我签出ndb_mgm配置，则每个节点似乎都正确连接：
ndb_mgm> show

Cluster Configuration
---------------------
[ndbd(NDB)] 2 node(s)
id=2 @10.0.10.20 (mysql-5.6.31 ndb-7.4.12, Nodegroup: 0, *)
id=3 @10.0.10.21 (mysql-5.6.31 ndb-7.4.12, Nodegroup: 0)
[ndb_mgmd(MGM)] 1 node(s)
id=1 @10.0.10.10 (mysql-5.6.31 ndb-7.4.12)
[mysqld(API)] 2 node(s)
id=4 @10.0.10.30 (mysql-5.6.31 ndb-7.4.12)
id=5 @10.0.10.31 (mysql-5.6.31 ndb-7.4.12)
ndb_mgmd的配置：
[ndbd default]
NoOfReplicas=2
DataMemory=80M
IndexMemory=18M
[ndb_mgmd]
hostname=10.0.10.10
datadir=/var/lib/mysql-cluster
[ndbd]
hostname=10.0.10.20
datadir=/usr/local/mysql/data
[ndbd]
hostname=10.0.10.21
datadir=/usr/local/mysql/data
[mysqld]
hostname=10.0.10.30
[mysqld]
hostname=10.0.10.31
每个mysqld配置如下：
[mysqld]
ndbcluster
log-error=/var/log/mysql/error.log
在mysqld实例上运行群集状态不会显示错误：

如果我想在群集上手动创建表，我会收到以下错误：
mysql> CREATE DATABASE cluster;
Query OK, 1 row affected (0.00 sec)
mysql> CREATE TABLE cluster_test (name VARCHAR(20), value VARCHAR(20)) ENGINE=ndbcluster;
ERROR 1296 (HY000): Got error 4009 'Cluster Failure' from NDBCLUSTER
mysql> show warnings;

+-------+------+--------------------------------------------------+
| Error | 1296 | Got error 4009 'Cluster Failure' from NDBCLUSTER |
+-------+------+--------------------------------------------------+
1 row in set (0.00 sec)
我不知道从哪里获得详细的错误说明。如果我正确的Errno 13通常是某种权限错误，但每个节点都拥有对文件夹的正确权限（他们实际上写了一些文件）。如果您需要详细的文件夹权限列表，请告诉我。
谢谢你的建议！

目前问题尚未解决，但经过一些研究后，问题似乎是Docker中的AUFS存储。 I described here the issue.
我在图像中使用较少的图层。我在一个RUN指令中组合了很多命令。
以下是适用于我的Dockerfiles：
mysql守护程序：
FROM ubuntu
RUN apt-get update && \
apt-get install -y libcam-pdf-perl build-essential libaio1 libaio-dev && \
cpan File::Copy \
Sys::Hostname \
Data::Dumper
// .. install mysql cluster files to /usr/local/mysql
WORKDIR /usr/local/mysql
RUN groupadd mysql && \
useradd -g mysql -s /bin/false mysql && \
chown -R root . && \
chown -R mysql data && \
chgrp -R mysql . && \
scripts/mysql_install_db --user=mysql
ENV PATH=/usr/local/mysql/bin:$PATH
USER mysql
<强> NDBD ：
FROM ubuntu
// .. install mysql cluster files to /usr/local/bin
RUN chmod +x /usr/local/bin/ndb* && \
mkdir -p /usr/local/mysql/data
<强> ndb_mgm ：
FROM ubuntu
// .. install mysql cluster files to /usr/local/bin
RUN chmod +x /usr/local/bin/ndb_mgm* && \
mkdir -p /var/lib/mysql-cluster
也许这有助于某人！
