Slurmctld：错误：mysql_real_connect失败：1045用户'root'@'localhost'访问被拒绝（使用密码：NO）

Question

我无法解决以下问题：

我正在使用 mariadb Ver 15.1 Distrib 10.6.16-MariaDB，对于使用 EditLine 包装器的 debian-linux-gnu (x86_64) 并且我之前尝试过以下修复：

MariaDB [(none)]> ALTER USER 'root'@'localhost' IDENTIFIED BY 'PASSWD';
MariaDB [(none)]> flush privileges;
MariaDB [(none)]> USE mysql;
MariaDB [mysql]> SELECT User, Host, plugin FROM mysql.user;
+-------------+-----------+-----------------------+
| User        | Host      | plugin                |
+-------------+-----------+-----------------------+
| mariadb.sys | localhost | mysql_native_password |
| root        | localhost | mysql_native_password |
| mysql       | localhost | mysql_native_password |
| slurm       | localhost | mysql_native_password |
| slurm       | system0   | mysql_native_password |
+-------------+-----------+-----------------------+
quit
#systemctl restart mariadb

但是后来我得到了

slurmctld: error: mysql_real_connect failed: 1698 Access denied for user 'root'@'localhost' 

。

我期望 slurmctld.service 与其他服务 slurmd 和 slurmdbd 一样活跃。

Answer 1

控制器似乎配置为使用

slurmdbd

服务进行记账 (

accounting_storage/slurmdbd

)，但它尝试直接访问 MySQL 数据库。因此我猜测

jobcomp/mysql

插件也处于活动状态。错误消息似乎表明未设置

JobCompPass

。

因此您可以

• 停用

  jobcomp/mysql

  插件，因为它与

  accounting_storage/slurmdbd

  插件是多余的；或
• 将

  JobCompPass

  设置为

  root

  MySQL 用户
的密码
