How to migrate artiafactory derby database to mysql database?

August 13, 2021 comments off

Step 1 – Check mysql version supported by artiafactory 7.x

Artifactory supports MySQL v5.5, 5.6, 5.7 and 8.x with InnoDB engine which is the default provided.

Step 2 – Take a full import of System

System Export from the currently running instance by opening from Artifactory UI -> Admin -> Import & Export -> System. Select the Exclude Content checkbox. By selecting this, we export only the configurations from Artifactory but not the binary data.

Step 3 – Setup a mysql server, database and permission

$ docker run --name mysql8 -v /tmp/database:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -e MYSQL_DATABASE=artifactory -e MYSQL_USER=artifactory -e MYSQL_PASSWORD=artifact123 -d mysql

Step 4 – Stop artiafactory server

$ cd /opt/artifactory-pro-7.23.3/app/bin
$ ./artifactory.sh stop

Step 5 – Make databases changes in property file of artiafactory

  • Copy a following section of mysql from system.full-template.yaml
$ more /opt/artifactory-pro-7.23.3/var/etc/system.full-template.yaml

    ## Example for mysql
    ## uncomment below to use database type
    ##type: mysql
    ##driver: com.mysql.jdbc.Driver
    ##url: "jdbc:mysql://<your db url, for example: localhost:3306>/artdb?characterEncoding=UTF-8&elideSetAutoCommits=true&useSSL=false"
    ##username: artifactory
    ##password: password
  • Make a changes in /opt/artifactory-pro-7.23.3/var/etc/system.yaml with following content
   ## Example for mysql
    ## uncomment below to use database type
    type: mysql
    driver: com.mysql.jdbc.Driver
    url: "jdbc:mysql://172.17.0.2:3306/artifactory?characterEncoding=UTF-8&elideSetAutoCommits=true&useSSL=false"
    username: artifactory
    password: artifact123
shared:
  database:
    type: mysql
    driver: com.mysql.jdbc.Driver
    url: jdbc:mysql://<your db url, for example: localhost:3306>/artdb?characterEncoding=UTF-8&elideSetAutoCommits=true&useSSL=false
    username: artifactory
    password: password

Step 6 – Copy a mysql database driver to required location

  • Download the MySQL JDBC driver (available from the MySQL website) and copy the mysql-connector-java-.jar file into $JFROG_HOME/artifactory/var/bootstrap/artifactory/tomcat/lib directory.
$ cd /tmp
$ wget https://cdn.mysql.com//Downloads/Connector-J/mysql-connector-java-8.0.26.tar.gz
$ tar -zxvf mysql-connector-java-8.0.26.tar.gz
$ cp mysql-connector-java-8.0.26.jar /opt/artifactory-pro-7.23.3/var/bootstrap/artifactory/tomcat/lib/

Step 7 – Clean all logs so if errors are there – can be troubleshoot easily

$ cd /opt/artifactory-pro-7.23.3/var/log
$ rm -rf *

Step 8 – Start a artiafactory

$ cd /opt/artifactory-pro-7.23.3/app/bin
$ ./artifactory.sh start

$ ./artifactory.sh status
Using default router's certificate and private key
router is running (PID: 28404)
metadata is running (PID: 28550)
event is running (PID: 28662)
frontend is running (PID: 28778)
Artifactory is running, on pid=28856

Step 9 – Import all the files which we got as part of Step2.

To migrate your existing database:

Import the metadata using Full Import and Export (optional for migration, not required for a new installation). Changing the database does not automatically transfer your data to the new database.

Verify the Migration from Derby to Mysql

Check Artifactory running or not

$ ./artifactory.sh status

Chec a Browsers if its Functioning well or not. Wait 2-3 mins.

Come inside a container

$ docker exec -it 916877c4a82c /bin/bash

Login to mysql using root

$ mysql -h localhost -u root -p

Validate Tables of Artifcatory Migration

show databases;
use artdb;
show tables;
exit

How to troubleshoot?

$ ./artifactory.sh status
$ cd /opt/artifactory-pro-7.23.3/var/log
Check a log for errors.
