As I said. I don't think any single additional step is needed, except setting database name, login and password in the container settings and using this information in Kodi to connect to the database.

April 28, 20233 yr I've done a totally newb thing, I lost my acess to my databse. I hsould start with I had a fully functioning database, with nextcloud running. I want to say I'm totally new to unraid and the docker. I am using adminer to access the databse to make change, created users for the nextcloud database and such. I'm alittle more familiar with phpmyadmin and was trying to get that to connect to mairiadb. I was getting frustrated becuase I could not wrap my head around why it wasnt connecting. So in frustration I changed the root user pw inside mariadb beacuse I couldnt find the mariadb password when I set it up. Stupid me found the it too late. Onece I change the pw it kicked me out of mariadb, wanting me to log back in and to connect to a database. The databse is still there running becasue nextcloud is stull functioning. Is there any way to recover this?

And depending on the container it is sometimes USER, UID, PUID etc and as far as I know maria db doesn't have such an option. Regarding your compose question: Ask in the compose support thread. I'm not supporting this plugin.

Thanks for the advice. i was able to get back in, also created a second mariadb to import in to. Still wet behind the ears. Lots to learn.
May 12, 20233 yr On 7/3/2021 at 4:12 AM, mgutt said: You mean, if you need two databases? Then install the container twice, change the name and the paths in both containers. This would be the easiest option. For example you could name one container "nextcloud_db" and the other "npm_db" and so on. is this the recoomended guidance vs multiple databases inside the same docker isntance? i am currently running a single instance with dbs for nextcloud and photoprism. i did recently had to rebuild due to errors/corruption that i tried to recover from so i am wondering if that was the cause or an update along the way.
May 12, 20233 yr 1 hour ago, morreale said: is this the recoomended guidance vs multiple databases inside the same docker isntance? Yes, containers share many resources, so there is negligible waste by duplicating containers, and the benefit of keeping the changeable data separate is clear, especially for recovery like you are doing. If you eat sleep and breathe database building and maintenance, then maybe keeping multiple databases in a single container would be easier for you to manage, but for us mere mortals that often have to resort to copying from backups for disaster recovery, separate containers is the way to go.
May 12, 20233 yr Author 4 hours ago, morreale said: is this the recoomended guidance vs multiple databases inside the same docker isntance? I think using multiple containers for multiple databases is the best way to go. By that nothing depends on each other. You don't need SQL commands to manually create additional users and databases. You can monitor usage, load and problems for each application separately. You can have different database versions if some applications aren't compatible to most recent versions....
June 10, 20233 yr I am starting over with Mariadb but after I've removed the docker and the image the "add container" page seems to be keeping some old settings including remembering the old pull I did from the repository. How do I make sure that everything is properly deleted before I reinstall it? Also I want to start fresh with Nextcloud but preserve the database specifically for Nextcloud. So second question should I use something like krusader or a file manager to move it out and move it back in after reinstall?

My dockers disappeared so I deleted the docker.img and reinstalled my dockers. Most went right to where I left them but I cannot get nextcloud reconnected to mariadb. Adminer says "MySQL server has gone away". I keep getting a repeating error when view mariadb logs. I can't find any info on the .err cat: /var/run/mysqld/mysqld.pid: No such file or directory 230606 18:23:41 mysqld_safe Logging to '/config/databases/66cb7795ae82.err'. 230606 18:23:41 mysqld_safe Starting mariadbd daemon with databases from /config/databases Caught SIGTERM signal! Any ideas of how I can correct this? What does the .err say? This just happened to me a couple of weeks ago but I only just noticed yesterday. My .err said something about "upgrade after crash is not supported" over and over but I was able to get around it.

After selecting the container through the drop-down, you will see a delete icon. Or go to apps > previous apps and delete the template there (both do the same). But this deletes only your changes on the template. If you want to delete the files, too, then you need to delete the subfolder of the container under /appdata. The file manager plugin is useful in this case.
June 10, 20233 yr Since last update i'm getting. /usr/local/bin/docker-entrypoint.sh: line 592: exec: mysqld_safe: not found

Then I just deleted mariadb altogether and the image to start fresh. When I went to reinstall it on the apps page it had the old repo and password prefilled making me think there's some remnants around.

And this thread is only for the official one. 4 hours ago, TheFabby said: Since last update i'm getting. /usr/local/bin/docker-entrypoint.sh: line 592: exec: mysqld_safe: not found Are you using the official container?! My update was successful. 9 hours ago, Joshwaaa said: I am starting over with Mariadb As far as I remember you used Adminer to manually create multiple databases in a single container. Do not do this! Instead install one MariaDB container per database (simply change the name and paths). This is how containers are meant to use. And of course you should think about daily backups! At least before installing updates!
June 11, 20233 yr Yep, i'm sure its the official one. Both my MariaDB's won't boot anymore with this same error. Simple update caused this. Edited June 11, 20233 yr by TheFabby
June 11, 20233 yr Author 6 hours ago, TheFabby said: Simple update caused this. "mysqld_safe: not found" happens usually if the user tries to reset its root password. Did you try that in the past and forget to undo something? Like a special post argument? Or did you add something to a config file?
June 25, 20233 yr Is there a way to quickly and easily rename a database without losing all the data?
July 23, 20232 yr Hi guys - hoping someone can help me. I changed from macvlan to ipvlan and everything seemed ok. I then tried to update nextcloud and it seems to want to create a new admin account.

Hey. So unfortunately these forums seem to be a bit of a ghost town recently! I am sure I have done something wrong with my new server setup that has broken everything, and I initially blamed macvlan. I actually think the mover is breaking my dockers. So, today, I will be deleting some dockers, and making sure only the cache drive is used for Appdata, Domains & System. I'll kick off the mover, then delete some dockers, and start again. I think with the multiple databases, you can do it that way, but I think they recommend 1 mariadb per database is that it is potentially easier to manage! I'm not really a db guy so I am not sure if you can do what you want to do. It sounds like a permissions issue though.

A little feedback on that: This is not a place to help users of other containers like the one of Linuxserver and users using the command line to create multiple databases are additional special scenarios I'm not really willed to help only because some YouTubers are spreading bad How-Tos 1 hour ago, Killabee44 said: copying the different DB folder This is not recommend.
