实施NDB Cluster后无法连接到MySQL数据库

问：

我正在尝试从 mysql 数据库的单个实例转变为使用集群进行冗余，按照我从这里找到的步骤，我认为这是我需要的解决方案，但现在我收到一个错误，我似乎找不到在线解决方案。我已经创建了集群config.ini文件，并修改了mysql的my.cnf文件以指向我的管理服务器，但是当我现在尝试连接到MySQL时，我收到一个错误，我无法弄清楚到底出了什么问题。NDB 管理器说一切正常，MySQL 成功退出，错误代码为 0 表示成功，但它一直处于“服务器启动正在进行中”的状态，并给了我一个错误 22 的“无效参数”。请帮忙，我已经做了一个多星期了，我一辈子都想不通。ERROR 2013 (HY000): Lost connection to MySQL server at 'reading initial communication packet', system error: 104

systemctl status ndb_mgmd返回：

尝试连接然后输入密码会给出：mysql -u root -p

/etc/mysql/my.cnf：

#
# The MySQL database server configuration file.
#
# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
#
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

# * IMPORTANT: Additional settings that can override those from this file!
#   The files must end with '.cnf', otherwise they'll be ignored.

我已经对 IP 地址进行了三倍检查，但自从我开始尝试使用第二个单元进行集群以来，我什至无法连接到 MySQL 进行任何进一步的测试。如何解决这个问题？
