Sphinx
Creating and maintaining a Sphinx index on your MySQL table.
- Installing Sphinx alongside MariaDB
Download and install from binaries.
Create a Linux user: `sphinxsearch` Create a folder /var/sphinxsearch/
Copy config file sphinx.conf to /var/sphinxsearch/ containing:
chown -R sphinxsearch:sphinxsearch /var/sphinxsearch
- Adding a MariaDB internal client for Sphinx
In MariaDB:
`INSTALL SONAME 'ha_sphinx';` (only once, to install the engine)
`CREATE DATABASE sphinx;` (only once per project, could be named sphinx_sku)
USE sphinx; CREATE TABLE sku_attributes (
id BIGINT UNSIGNED NOT NULL, weight INTEGER NOT NULL, query VARCHAR(3072) NOT NULL, group_id INTEGER, INDEX(query)
) ENGINE=SPHINX CONNECTION="sphinx://127.0.0.1:9312/sku_attributes";
Once every time we add an index to Sphinx. This table is our MariaDB gateway to query the Sphinx index.
Adding another index: USE sphinx; CREATE TABLE sku_products (
id BIGINT UNSIGNED NOT NULL, weight INTEGER NOT NULL, query VARCHAR(3072) NOT NULL, group_id INTEGER, INDEX(query)
) ENGINE=SPHINX CONNECTION="sphinx://127.0.0.1:9312/sku_products"
- Creating an index with MySQL source.
- Populating the index.
- Updating the index.
- Creating a Real Time index.
- Updating the index.
- Querying the index alone.
`SELECT * FROM sphinx.sku_attributes WHERE query="simple and easy to install";`
- Joining the results with MariaDB records.
Querying the index but fetching data directly from our MariaDB equivalent table:
SELECT * FROM sphinx.sku_attributes sp_a LEFT JOIN sku_io.product_attributes pa ON pa.id = sp_a.i d WHERE sp_a.query="simple and easy to install";
