Creating and maintaining a Sphinx index on your MySQL table.
Contents
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.
Querying the index via direct connection to searchd daemon.
Querying the index alone from within MariaDB.
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";
