Migrate MySQL to PostgreSQL on the same machine. Xxx=# SELECT * FROM source_db.sample_table Ħ. Check to see if your PostgreSQL database contains the moved data: Connect to the target database that loads the data.Ĭ. Postgres-server$ sudo -i -u postgres psqlī. $ pgloader useSSL=true postgresql:// Check the migration. Postgres-server$ sudo update-ca-certificatesĤ. Postgres-server$ sudo cp ~/client-ssl/client-cert.pem /usr/local/share/ca-certificates/ Postgres-server$ sudo cp ~/client-ssl/ca.pem /usr/local/share/ca-certificates/ca.pem.crt Do not forget to change the names of these files to include the.crt file extension. Add the ca.pem and client-cert.pem files to Ubuntu’s trusted certificate store to enable the SSL for Pgloader. GRANT ALL ON source_db.* TO ' Reload the grant tables to enable privilege changes.į. Grant newly created MySQL user access to the target. Mysql> CREATE USER IDENTIFIED BY 'password' REQUIRE SSL Ĭ. Replace the your_postgres_server_ip with the public PostgreSQL IP address and password with a safe one or passphrase. Create a MySQL dedicated user and manage certificates.ī. Postgres-server$ sudo -u postgres createdb xxxģ. Create a target database to load the source data. Shall the new role be a superuser? (y/n) yĮ. Classify the new role as a superuser for the broad privileges. Enter and confirm the password for the role.ĭ. Then the script will prompt for a new role name.Ĭ. Postgres-server$ sudo -u postgres createuser -interactive -Pī. P flag requests a password for the new role. This tutorial will present you have to set up a PostgreSQL role with password authentication.Ī. When a role authenticates using the ident method and has the same name as the Linux user profile issuing the pgloader command, Pgloader can load data into a Postgres database using that role. PostgreSQL database users can be authenticated through identification protocal/ident (by default) and password, while the default option offers greater security, it brings problems for external connection. Test the Pgloader version to confirm it is installed.Ģ. Move the binary file into the /usr/local/bin directory. Navigate to the release page of GitHUb project, find the latest version> Assets> copy the Source code (tar.gz) link, paste into the curl command, and replace the https URL.Į. Postgres-server$ sudo apt install sbcl unzip libsqlite3-dev gawk curl make freetds-dev libzip-devĬ. Input the following commands and press Enter to install dependencies of Pgloader. Update the package index of the Postgres server.ī. You can install Pgloader from the Ubuntu APT repositories using the apt command, but to use the useSSL option in v3.5.1 and later, you’ll have to install from the GitHub repository using the source code.Ī. Use PostgreSQL server as the client machine of MySQL. Root MySQL user authenticates with a password and accepts encrypted connections. Prerequisites:Īccess to servers that set up a firewall and a non-root user with sudo rights. Pgloader is a free database migration tool that allows users to implement continuous migration from MySQL, SQLite, and MS SQL Server to PostgreSQL. Migrate MySQL to PostgreSQL with Pgloader If you are after MySQL migration to PostgreSQL (see convert PostgreSQL to MySQL), this blog will introduce two conversion methods. Whereas PostgreSQL shines in analytics, data mining environments, and data warehouses since the database has better querying, query optimizing, and query answering abilities, as opposed to the vulnerabilities of MySQL in these environments. Typically, MySQL is often used as a small web database for organizations that have carefully tuned, reviewed, and relatively simple application-generated queries (especially those that can use PRIMARY KEYs). MySQL vs PostgreSQL are two popular open-source choices among them and rank the top 5 databases in the rankings that capture global attention.īased on different use cases, a business that involves complex longer-running queries, advanced query needs like joins, analytics, window, etc., or ACID-consistent data requirements, may find that PostgreSQL is a preferred option compared to MySQL. Relational database management systems (RDBMS) are widely deployed across industries from e-commerce, and website, to financial services and geographical designs. Backup MySQL and PostgreSQL Before and After Database Migration.Migrate MySQL to PostgreSQL with Py-mysql2pgsql.Migrate MySQL to PostgreSQL with Pgloader.SQLSTATE could not connect to server: Connection refused Is the server running on host "localhost" (127.0.0. But.īut due to specific configurations files in my project, I need that the postgres server name be localhost. With a docker-compose up -d and then on localhost:8080 I can connect to postgres : Let's say I want a docker-compose.yml that sets 2 services : a postgresql server and adminer (a kind of phpmyadmin).
