Traccar MariaDB

Try entering your synology IP into the config as per

<entry key='database.url'>jdbc:mysql://192.168.1.112:3306/traccar?serverTimezone=UTC&amp;useSSL=false&amp;allowMultiQueries=true&amp;autoReconnect=true&amp;useUnicode=yes&amp;characterEncoding=UTF-8&amp;sessionVariables=sql_mode=''</entry>

As Anton said, localhost in the container is likely not localhost on the host (mine wasnt but I'm using 2 containers on a Synology NAS).

Same error with :

<entry key='database.url'>jdbc:mysql://192.168.1.100:3306/traccar?serverTimezone=UTC&useSSL=false&allowMultiQueries=true&autoReconnect=true&useUnicode=yes&characterEncoding=UTF-8&sessionVariables=sql_mode=''</entry>

I think you have to use the bridge ip address of your host.

Same error with :

<entry key='database.url'>jdbc:mysql://172.17.0.1:3306/traccar?serverTimezone=UTC&useSSL=false&allowMultiQueries=true&autoReconnect=true&useUnicode=yes&characterEncoding=UTF-8&sessionVariables=sql_mode=''</entry>

can you connect to your mysql from outside of your NAS ?

Do you have the firewall on the synology enabled (if you do you may need to open the port).

And also check if your database is configured to accept remote connection, which is usually not the default.

I don't know how to test my connection from the outside, however via PhpMyadmin it works and I don't know how to check if it's authorized from the outside :(

I checked Enable TCP/IP connection on port 3306.

Domain socket /run/mysqld/mysqld.sock

on your synology, with root access, you should be able to connect to your mysql using

mysql -h 127.0.0.1  -p

enter your password, then enter

show grants;

you should get something like

MariaDB [(none)]> show grants;
+--------------------------------------------------------------------------------------------------------------------------------+
| Grants for root@%                                                                                                              |

+--------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.000 sec)

in the above, the 'root'@'%' the '%' part says you can connect from any IP. Typically by default it has something like 'root'@'localhost'

you may be able to enter

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'PASSWORD' WITH GRANT OPTION;
FLUSH PRIVILEGES;

the above should grant access from any IP for user root with the password you specify.

in the above, it should be GRANT ALL PRIVILEGES ON . TO it seemed to remove the . from it

Here is what I get:

root@Onehebergeur:/volume1/@docker/aufs/diff/9f6c4f6e7c031b8e23b7206f16f2ae180709d8ccb88e52ef7e02fc63112e67a3/opt/traccar/conf# mysql -h 127.0.0.1 -p

You need to enter the command

show grants;

in the previous post, it should be GRANT ALL PRIVILEGES ON *.* TO it seemed to remove the *.* from it (I had to escape them)

also, in the command change PASSWORD to your own value or the password will be PASSWORD

Sorry for the delayed response. Its taking a while to respond as the forum is limiting the frequency of my responses.

I may leave it till tomorrow as its getting late here (after 10:30pm).

I dont know why both lines have 'root'@'localhost' in them. One should have had 'root'@'%'

Both lines look like they will only allow localhost to connect to them which would prevent a container from connecting to it.

I think you'll need to look at that link I sent you and try to get an entry with 'root'@'%' listed.

It may also be possible that you might have to exit mysql then go back in to see the new privileges with the "show grants;" command.
