ndb_mgmd 守护进程未启动
我想配置一个 NDB Mysql 集群，我按照其官方页面的文档进行操作。安装 mysql-cluster-community 7.5 版本，我有以下方案
1个管理节点：192.168.10.137
2个节点mysqld：192.168.10.140,192.168.10.139
2个数据节点：192.168.10.138,192.168.10.141
这是管理器的配置文件，我的config.ini；
[ndbd default]
# Options affecting ndbd processes on all data nodes:
NoOfReplicas = 2 # Number of replicas
DataMemory = 80M # How much memory to allocate for data storage
IndexMemory = 18M # How much memory to allocate for index storage
# For DataMemory and IndexMemory, we have used the
# default values. Since the "world" database takes up
# only about 500KB, this should be more than enough for
# this example NDB Cluster setup.
ServerPort = 1186 # This the default value; however, you can use any
# port that is free for all hosts in the cluster
# Note1: It is recommended that you do not specify the port
# number at all and simply allow the default value to be used
# instead
# Note2: The port was formerly specified using the PortNumber
# TCP parameter; this parameter is no longer available in NDB
# Cluster 7.5.
[ndb_mgmd]
# Management process options:
HostName = 192.168.10.137 # Hostname or IP address of MGM node
DataDir = / var / lib / mysql-cluster # Directory for MGM node log files
NodeId = 1
[ndbd]
# Configuration for the data node with ip 139
# (one [ndbd] section per data node)
HostName = 192.168.10.139 # Hostname or IP address
NodeId = 2 # Node ID for this data node
DataDir = / usr / local / mysql / data # Directory for this data node's data files
[ndbd]
# Configuration for the data node with ip 140
HostName = 192.168.10.140 # Hostname or IP address
NodeId = 3 # Node ID for this data node
DataDir = / usr / local / mysql / data # Directory for this data node's data files
[mysqld]
# SQL node options:
HostName = 192.168.10.138 # Hostname or IP address
[mysqld]
# SQL node options:
HostName = 192.168.10.141 # Hostname or IP address
这是节点的配置文件：
[mysqld]
# Options for mysqld process:
ndbcluster # run NDB storage engine
[mysql_集群]
# Options for NDB Cluster processes:
ndb-connectstring = 192.168.10.137 # location of management server
当我尝试告诉 mysql 配置文件是什么时，它告诉我以下内容：
root @ mysql: /etc/mysql/mysql.conf.d# ndb_mgmd -f /var/lib/mysql-cluster/config.ini
bash: ndb_mgmd: Order not found
但是如果我使用命令“ndb_mgm”如果我输入这部分：
- NDB Cluster - Management Client -
ndb_mgm>
如果从那里我指示顺序：
-f /var/lib/mysql-cluster/config.ini
它告诉我以下内容：
Unable to connect with connect string: nodeid = 0, localhost: 1186
我尝试从 config.ini 文件所在的文件夹启动 ndb_mgm，但无法执行它。抱歉我的英语不好。
