MySQL集群错误: 1005: Can't create table 'ndb_schema' (errno: 13)

标签 mysql cluster-computing

我的 MySQL 集群测试设置遇到问题:

我有两台运行 Ubuntu 和 Docker 的机器(使用多主机网络)和每个节点(ndb_mgm、ndbd 和 mysqld)通过 Docker 运行。设置如下:

机器 1:

  • ndb_mgmd
  • ndbd1
  • mysqld1

机器 2:

  • ndbd2
  • mysqld2

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，但无法创建表，整个NDB日志都在mysqld<上 重新开始后的实例:

最后一行显示，它无法创建表:

NDB: Query 'CREATE TABLE ...' failed, error: 1005: Can't create table 'ndb_schema' (errno: 13)

如果我检查 ndb_mgm 配置，每个节点似乎都已正确连接:

ndb_mgm> show

ndb_mgmd的配置:

[ndbd default]

DataMemory=80M
IndexMemory=18M

[ndb_mgmd]
hostname=10.0.10.10
datadir=/var/lib/mysql-cluster

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实例上运行集群状态没有显示错误:

如果我想在集群上手动创建表，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

| Error | 1296 | Got error 4009 'Cluster Failure' from NDBCLUSTER |
+-------+------+--------------------------------------------------+
1 row in set (0.00 sec)

我不知道在哪里可以获得详细的错误描述。如果我是对的，Errno 13 通常是某种权限错误，但每个节点都对文件夹具有正确的权限(它们实际上写入了一些文件)。如果您需要详细的文件夹权限列表，请告诉我。

谢谢指教!

最佳答案

目前问题还没有解决，但经过一番研究，问题似乎出在Docker内部的AUFS存储上。 I described here the issue.

我在图像内使用较少的层使其工作。我在一个 RUN 指令中组合了很多命令。

以下是适合我的 Dockerfile:

mysql 守护进程:

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

ndbd:

FROM ubuntu

// .. install mysql cluster files to /usr/local/bin

RUN chmod +x /usr/local/bin/ndb* && \
    mkdir -p /usr/local/mysql/data

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

也许这对某人有帮助!
