[Maria-discuss] problems getting MariaDB to start after install
by Tim McConnell 03 Jan '23

03 Jan '23

Hello list, I have installed and re-installed MariaDB trying to get prelude to work and I'm at a loss. When I try to run 'sudo systemctl start mariadb.service' I get these errors: Job for mariadb.service failed because the control process exited with error code. See "systemctl status mariadb.service" and "journalctl -xeu mariadb.service" for details. so I read the KB and found I'm supposed to use 'sudo systemctl status mariadb.socket' which gives this: ● mariadb.socket - MariaDB 10.6.11 database server (socket activation) Loaded: loaded (/lib/systemd/system/mariadb.socket; static) Active: active (listening) since Thu 2022-12-29 18:39:25 CST; 26s ago Until: Thu 2022-12-29 18:39:25 CST; 26s ago Triggers: ● mariadb.service Docs: man:mariadbd(8) https://mariadb.com/kb/en/library/systemd/ Listen: @mariadb (Stream) /run/mysqld/mysqld.sock (Stream) [::]:3306 (Stream) Tasks: 0 (limit: 8190) Memory: 4.0K CPU: 2ms CGroup: /system.slice/mariadb.socket and then if I try to run 'sudo mysqlcheck -A' I'll get this error: mysqlcheck: Got error: 2013: Lost connection to server at 'handshake: reading initial communication packet', system error: 104 when trying to connect I then check the status of the socket and get this output: sudo systemctl status mariadb.socket × mariadb.socket - MariaDB 10.6.11 database server (socket activation) Loaded: loaded (/lib/systemd/system/mariadb.socket; static) Active: failed (Result: service-start-limit-hit) since Thu 2022-12-29 18:4> Duration: 1min 11.173s Triggers: ● mariadb.service Docs: man:mariadbd(8) https://mariadb.com/kb/en/library/systemd/ Listen: @mariadb (Stream) /run/mysqld/mysqld.sock (Stream) [::]:3306 (Stream) CPU: 2ms I then ran 'sudo journalctl -n 20 -u mariadb.service' (as per the kb) and get: Dec 29 19:12:45 DebianTim mariadbd[3660996]: 2022-12-29 19:12:45 0 [Note] /usr/sbin/mariadbd (server 10.6.11-MariaDB-1) starting as process 3660996 ...

Thanks in advance for any help. -- Tim McConnell <tmcconnell168(a)gmail.com>

[Maria-discuss] debian 11 + mariadb remote connections
by Aaron Axelsen 29 Dec '22

29 Dec '22

Howdy all! I'm having trouble figuring out why a new install on a debian 11 box of mariadb 10.10 is not allowing remote connections. I'm really at a loss for what's going on. I've adjusted the bind address and made sure it's setup for remote connections. From this box, I am able to access mysql using 127.0.0.1, 192.168.0.143 or the external IP without any issue. When trying to connect from any other box, it's acting like it's blocked by the firewall. * iptables is what I generally use but i've cleared out all rules, flushed all tables, and all policies are set to accept. * There is no firewall running from my cloud host - verified with their support team. * Other services are connecting just fine externally, which would really point towards an issues specific with mariadb. MariaDB is currently binding to app ipv4 and ipv6 interfaces. I've tried having only bind to ipv4, changing the default port to something other than 3306. I even went as far as spinning up a test server, same config and it's working as expected. This server is setup for email - so it's also running postfix, dovecot, rspam, redis and apache. Any suggestions or thoughts are greatly appreciated! -- Aaron Axelsen

[Maria-discuss] MySQL Workbench Issue
by Software Info 28 Dec '22

28 Dec '22

Hi All, I have a very strange problem here. I have mariadb 10.6.10 running on FreeBSD 13.1. I have SSL enabled globally. When I use MySQL workbench to log on from Windows 10 machines, I can authenticate but when I use the same credentials to log on from a Windows 2012 server, I cannot. I get the error user access denied. The credential is configured to log on from anywhere. Is there some kind of SSL/TLS incompatibility in Windows 2013 that anyone knows of? Any help would be appreciated. Best regards, SI

[Maria-discuss] DBMS vs Storage Engine Alone
by Jonathan M. Wilbur 20 Dec '22

20 Dec '22

Sorry to ask this question here, since it is not strictly MariaDB-related, but I need the knowledge of people that develop with databases: is there significant overhead to using a DBMS versus a storage engine directly? I have a project for which speed / latency is very important, and I was wondering if I could make significant performance gains by using a storage engine (such as WiredTiger, RocksDB, LevelDB, etc.) directly instead of using a DBMS (like MariaDB). More concretely, are there any studies out there on this to give me some objective numbers on this? Assume it is over a local loopback connection, so pretty much only the overhead of the networking itself would apply. Thank you in advance, - Jonathan M. Wilbur

[Maria-discuss] flush tables with read lock blocks
by Alex 13 Dec '22

13 Dec '22

Hi, I'm using mariadb-10.5.18-1.fc37.x86_64 on fedora37 set up as a master server. There are currently two or three slaves configured and operating properly. I'm trying to add another slave, and for some reason when I try to flush tables with read lock, then dump the databases to be transferred to the new slave, mysqldump just prints: -- Connecting to localhost... At first I didn't realize it, but soon the database stopped responding to all clients until I released the lock with "unlock tables". I'm following these directions: https://mariadb.com/kb/en/setting-up-replication/ What could I be doing wrong? Here are the my.cnf options that I believe could be related to my issue. Any ideas greatly appreciated. The server has 128GB of RAM.
