无法使用GTID

Question

通过配置文件没办法开启gtid,重启mysql后也没用.可以进入mysql设置临时的,但是服务一重启就又变成gtid_model=off.
Mysql版本5.7和8.0都试过不行.
配置

gtid_mode = on
enforce_gtid_consistency = on
master_info_repository = TABLE
relay_log_info_repository = TABLE

MySQL [(none)]> show variables like '%gtid%';
+----------------------------------+-----------+
| Variable_name                    | Value     |
+----------------------------------+-----------+
| binlog_gtid_simple_recovery      | ON        |
| enforce_gtid_consistency         | OFF       |
| gtid_executed_compression_period | 1000      |
| gtid_mode                        | OFF       |
| gtid_next                        | AUTOMATIC |
| gtid_owned                       |           |
| gtid_purged                      |           |
| session_track_gtids              | OFF       |

你的系统中可能存在着多个my.cnf文件，MySQL在启动时会按顺序应用my.cnf文件的配置，并且后面应用的会覆盖前面的配置。你可以使用find / -name my.cnf查找一下看看。

  系统就一个my.cnf的.

  在MySQL8.0中用set persist gtid_mode=on 试一下。

  还是不行,是不是我虚拟机装的mysql,又问题？8.0安装:wget -c http://mirrors.linuxeye.com/oneinstack-full.tar.gz && tar xzf oneinstack-full.tar.gz && ./oneinstack/install.sh --db_option 1 --dbinstallmethod 1 --dbrootpwd qvbilam   5.7安装:wget -c http://mirrors.linuxeye.com/oneinstack-full.tar.gz && tar xzf oneinstack-full.tar.gz && ./oneinstack/install.sh --db_option 2 --dbinstallmethod 1 --dbrootpwd qvbilam   文档:https://oneinstack.com/docs/lnmptstack-image-guide/
