So, I just want to know what's the relationship between the xinetd and the mysql

  • These logs aren't relevant to why MariaDB isn't starting. [`mysqlchk`](https://gist.github.com/aw/1071141) is an xinetd service configuration for checking the status of MySQL using an HTTP request. Since your host is `ha-node1`, with "ha" meaning (presumably) "high availability" as in HAProxy, it would make sense if you have something like that set up... but it's only monitoring your database. Is that what you are trying to figure out? – Michael - sqlbot Aug 17 '17 at 09:29
  • @Michael-sqlbot Oh, yeah. i have 3 nodes to do the `mariadb cluster`, the cluster success, works perfect, and now I just want to start one, and the other two down, but I did not success start up only one mysql. – aircraft Aug 17 '17 at 10:12
