This article introduces the knowledge of "how to install Redis through URLOS". In the operation of practical cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Why use Redis technology

We all know that WordPress uses dynamic database query. Translated into vernacular, that is, when users visit articles or pages, they will send a query command to the database, and the database will return the query results after querying according to the command (there is no caching technology here). Obviously, if there are a lot of visits, the database will be queried frequently, which will slow down the website. If the performance of the server is not high, the website crashes instantly.

So we need a caching technology to reduce the number of database queries. And database caching technology is one of them. Redis technology is one of the best. Redis is a key-value distributed storage system. To put it simply, the query is based on the key value, which makes up for the deficiency of Memcached to a large extent. If the database is cached through Redis, the query speed will be faster and there will be more concurrency.

So the cooperation between Redis and WordPress is perfect.

How to install and enable Redis

If we are going to use Redis for WordPress caching, we need to install Redis on the server and turn it on.

We can manually enter the command line through the ssh tool to install and configure Redis, or we can use a simpler and faster way to install the wordpress website and Redis through URLOS. Why URLOS is recommended because it is as easy to deploy websites and various server applications as it is to install app from a mobile phone.

Install Redis

Wordpress and Redis can be installed directly through the URLOS application market, almost zero technology. For the management server, it is recommended to use URLOS, after all, professional matters are left to professionals to do.

Install plug-ins in the background of WordPress website and enable Redis support

In the WordPress management background, we can turn on Redis caching through the cache plug-in, and we introduce two ways to use it.

1. Use Redis Object Cache to search and install and activate the Redis Object Cache plug-in, which installs a php file that helps WordPress communicate with Redis. Navigate to the settings → Redis, then click Enable Object Cache and make sure the status displays Connected.

One thing to note here: we need to manually modify the object-cache.php file in the / wp-content directory:

$parameters = array ('scheme' = >' tcp', 'host' = >' 127.0.0.1, 'port' = > 6379)

Change 127.0.0.1 to the private network IP of the server (if URLOS automatically creates cluster nodes, you can use 172.17.0.1):

$parameters = array ('scheme' = >' tcp', 'host' = >' 172.17.0.1', 'port' = > 6379)

Then in wp-config.php, add define ('WP_CACHE_KEY_SALT','yourURL.com') to the file. You can use any unique string in the URL, but it is recommended that you use the URL of the website.

2. With WP Super Cache, Redis Object Cache and WP Super Cache can be used at the same time. After Redis is successfully enabled, you can turn on "use object cache system to store files" in the advanced configuration of WP Super Cache.
