### Connect
|
||
|
|
```
|
||
|
|
source mailcow.conf
|
||
|
|
docker-compose exec mysql-mailcow mysql -u${DBUSER} -p${DBPASS} ${DBNAME}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Backup
|
||
|
|
```
|
||
|
|
cd /path/to/mailcow-dockerized
|
||
|
|
source mailcow.conf
|
||
|
|
DATE=$(date +"%Y%m%d_%H%M%S")
|
||
|
|
docker-compose exec mysql-mailcow mysqldump --default-character-set=utf8mb4 -u${DBUSER} -p${DBPASS} ${DBNAME} > backup_${DBNAME}_${DATE}.sql
|
||
|
|
```
|
||
|
|
|
||
|
|
### Restore
|
||
|
|
|
||
|
|
You should redirect the sql dump without Docker-Compose to prevent parsing errors.
|
||
|
|
|
||
|
|
```
|
||
|
|
cd /path/to/mailcow-dockerized
|
||
|
|
source mailcow.conf
|
||
|
|
docker exec -i $(docker-compose ps -q mysql-mailcow) mysql -u${DBUSER} -p${DBPASS} ${DBNAME} < backup_file.sql
|
||
|
|
```
|
||
|
|
|
||
|
|
### Reset MySQL passwords
|
||
|
|
|
||
|
|
Stop the stack by running `docker-compose stop`.
|
||
|
|
|
||
|
|
When the containers came to a stop, run this command:
|
||
|
|
|
||
|
|
```
|
||
|
|
docker-compose run --rm --entrypoint '/bin/sh -c "gosu mysql mysqld --skip-grant-tables & sleep 10 && mysql -hlocalhost -uroot && exit 0"' mysql-mailcow
|
||
|
|
```
|
||
|
|
|
||
|
|
**1\. Find database name**
|
||
|
|
|
||
|
|
```
|
||
|
|
MariaDB [(none)]> show databases;
|
||
|
|
+--------------------+
|
||
|
|
| Database |
|
||
|
|
+--------------------+
|
||
|
|
| information_schema |
|
||
|
|
| mailcow_database | <=====
|
||
|
|
| mysql |
|
||
|
|
| performance_schema |
|
||

|

|
|
4 rows in set (0.00 sec)
|
||
|
|
```
|
||
|
|
|
||
|
|
**2\. Reset one or more users**
|
||
|
|
|
||
|
|
Both "password" and "authentication_string" exist. Currently "password" is used, but better set both.
|
||
|
|
|
||
|
|
```
|
||
|
|
MariaDB [(none)]> SELECT user FROM mysql.user;
|
||
|
|
+--------------+
|
||
|
|
| user |
|
||
|
|
+--------------+
|
||
|
|
| mailcow_user | <=====
|

|
|

|

|

|
|
2 rows in set (0.00 sec)
|
||
|
|
|
||
|
|
MariaDB [(none)]> FLUSH PRIVILEGES;
|
||
|
|
MariaDB [(none)]> UPDATE mysql.user SET authentication_string = PASSWORD('gotr00t'), password = PASSWORD('gotr00t') WHERE User = 'root' AND Host = '%';
|
||
|
|
MariaDB [(none)]> UPDATE mysql.user SET authentication_string = PASSWORD('mookuh'), password = PASSWORD('mookuh') WHERE User = 'mailcow' AND Host = '%';
|
||
|
|
MariaDB [(none)]> FLUSH PRIVILEGES;
|
||
|
|
```
