我正在尝试按照文档中概述的步骤设置 InnoDB 集群的生产部署（ https://dev.mysql.com/doc/refman/8.0/en/mysql-innodb-cluster-production-deployment.html ） . 我正在使用 MySQL 5.7.25
我的 MySQL 服务器成功启动并运行（从 MySQL Shell）
dba.checkInstanceConfiguration('root@localhost:3306')
哪个打印
Validating local MySQL instance listening at port 3306 for use in an InnoDB cluster...
This instance reports its own address as ip-10-0-3-184.ap-south-1.compute.internal
Clients and other cluster members will communicate with it through this address by default. If this is not correct, the report_host MySQL system variable should be changed.
Checking whether existing tables comply with Group Replication requirements...
No incompatible tables detected
Checking instance configuration...
Some configuration options need to be fixed:
+----------------------------------+---------------+----------------+--------------------------------------------------+
| Variable | Current Value | Required Value | Note |
+----------------------------------+---------------+----------------+--------------------------------------------------+
| enforce_gtid_consistency | OFF | ON | Update the config file and restart the server |
| gtid_mode | OFF | ON | Update the config file and restart the server |
| log_bin | <not set> | <no value> | Update the config file |
| log_bin | OFF | ON | Update read-only variable and restart the server |
| log_slave_updates | OFF | ON | Update the config file and restart the server |
| master_info_repository | FILE | TABLE | Update the config file and restart the server |
| relay_log_info_repository | FILE | TABLE | Update the config file and restart the server |
| server_id | 0 | <unique ID> | Update the config file and restart the server |
| transaction_write_set_extraction | OFF | XXHASH64 | Update the config file and restart the server |
+----------------------------------+---------------+----------------+--------------------------------------------------+
Some variables need to be changed, but cannot be done dynamically on the server: an option file is required.
Please use the dba.configureInstance() command to repair these issues.

（到目前为止，一切都很好）
在此之后我尝试运行dba.configureLocalInstance()，但我收到以下错误消息：
Dba.configureLocalInstance: Dba.configureLocalInstance: An open session is required to perform this operation. (RuntimeError)
我不确定这意味着什么，但为了尝试绕过它，我运行dba.configureLocalInstance('root@localhost:3306')它似乎有效：

WARNING: User 'root' can only connect from localhost.
If you need to manage this instance while connected from other hosts, new account(s) with the proper source address specification must be created.
1) Create remotely usable account for 'root' with same grants and password
2) Create a new admin account for InnoDB cluster with minimal required grants
3) Ignore and continue
4) Cancel
Please select an option [1]: 3

Detecting the configuration file...
Found configuration file at standard location: /etc/my.cnf
Do you want to modify this file? [y/N]: y
Do you want to perform the required configuration changes? [y/n]: y
Configuring instance...
The instance 'localhost:3306' was configured for InnoDB cluster usage.
MySQL server needs to be restarted for configuration changes to take effect.
但是在我重新启动 MySQL 服务器后，我得到了完全相同的输出dba.checkInstanceConfiguration('root@localhost:3306')......
我还注意到，/etc/my.cnf从初始安装开始，它的默认设置并没有被修改。如果这是一个权限问题，我将所有者更改为/etc/my.cnf我的用户“mysql”，但结果是一样的......
任何人都可以阐明它吗？任何帮助表示赞赏。
