There are numerous approaches to improve the accessibility of your Word Press site.
In this guide, I will show you how you can set up Word Press to utilize MySQL replication utilizing Hyper. Most importantly, what is HyperDB? What’s more, what is MySQL replication? Allow me to clarify both these things in short.
What is MySQL Replication?
In basic words, replication here methods replication of information base or information bases starting with one machine then onto the next. For this situation, you can set up an expert slave replication in MySQL to duplicate all the information from expert to slave in a split second. It implies that all your information is accessible to two workers rather than only one.
Presently, as we have our information on two workers, we can split the heap between two workers. If there should be an occurrence of expert slave replication, you can just embed, refresh, or erase information in an expert worker, the slave worker will duplicate the information from the ace worker. It implies that now the heap is on two workers rather than one. For instance, If your lord worker crashes, you won’t have the option to refresh anything from the administrator board yet your site will in any case be live because it is perusing information from Slave workers.
What is HyperDB?
HyperDB is a drop-in module of Word Press. It implies that you don’t need to introduce HyperDB by adding another module. It is only a PHP document that you need to transfer inside your Word Press establishment catalog; I will tell you precisely the best way to play out this errand.
Utilizing HyperDB, we can empower WordPress to utilize various workers for various sorts of questions. For instance, we can empower WordPress to utilize Master worker to run supplement, refresh, and erase questions while Slave worker to utilize read inquiries at whatever point a client demands the information.
It implies that relying upon the kind of question; WordPress will utilize the workers we notice in the HyperDB drop-in module. It is anything but difficult to set up. You can set it up shortly once you become accustomed to it. At long last, Let’s beginning with the guide.
Requirements
To follow this guide, You should have a WordPress site arranged for your worker.

Regardless of whether you are simply going to have a solitary site at present, It would be valuable for you to set up your worker along these lines.
Also, you should have MySQL replication set up. If you haven’t played out this assignment, follow these manuals to set up expert slave replication or expert replication in MySQL.

$ sudo able get introduce unfasten – y
$ wget https://downloads.wordpress.org/module/hyperdb.zip
$ unfasten hyperdb.zip
Once the download is finished, we need to move the documents accessible inside the hyperdb registry to our WordPress establishment catalog
MOVE AND UPDATE DB-CONFIG.PHP
Presently, Let’s turn and update our db-config.php record to our WordPress establishment registry. Much the same as a wp-config.php document, a db-config.php record will contain all the data pretty much all the information base workers associated with the WordPress site. Execute the accompanying order to move the db-config.php record to the WordPress establishment registry.

After moving a record, execute the accompanying order to open a document in alter mode.
$ sudo nano/var/www/model site.com/db-config.php
Presently, discover DB_HOST and overlook the main event. We simply need to refresh the subsequent event. The default arrangement will resemble the accompanying.
* This adds a similar worker once more, just this time it is arranged as a slave.
* The last three boundaries are set to the defaults yet are appeared for lucidity.
$wpdb->add_database(array(
‘have’ => DB_HOST,/If port is other than 3306, use host:port.
‘client’ => DB_USER,
‘secret word’ => DB_PASSWORD,
‘name’ => DB_NAME,
‘compose’ => 0,
‘peruse’ => 1,

$ reverberation “define(‘SLAVE_HOST’,’IP_ADDRESS_OF_SLAVE’);” | sudo tee – a/var/www/model site.com/wp-config.php
Supplant the hued part in the code. It is a one-line order to add one line toward the finish of the wp-config.php document. You can likewise open the record to alter the mode and add the line physically, it doesn’t have any effect.
MOVE DB.PHP TO WP-CONTENT
In the last advance, we simply need to move the db.php document from the hyper db registry to our WordPress establishment’s wp-content index. Execute the accompanying order to move the record.
$ sudo mv ~/hyperdb/db.php/var/www/model site.com/wp-content/
