Set the correct permissions with: chmod 770 /var/lib/redis Step 4. Give the redis user and group ownership over the directory: chown redis: /var/lib/redis Next create the /var/lib/redis directory which will store the redis databases: mkdir -p /var/lib/redis The following commands will create a group and user named “redis”: groupadd redisĪdduser -system -g redis -no-create-home redis
The next step is to install Redis binaries using the make install command: make install Now, run the make test command to make sure everything was built correctly: make test Make: Leaving directory `/usr/local/src/redis-5.0.0/src'
The build process may take some time depending on your server resources, once completed the following message will be printed on your screen: Hint: It's a good idea to run 'make test' ) Start the compilation process using the make command: make Navigate to the Redis source directory: cd redis-5.0.0
Once the download has completed, extract the downloaded file with the following tar command: tar xf redis-5.0.0.tar.gz
The installation process is quite an easy task, start by navigating to the /usr/local/src/ directory: cd /usr/local/srcĭownload the Redis archive by running the following wget command: wget Install Redis 5.0 on CentOS 7Īt the time of writing this article, the latest stable version of Redis was 5.0.0. Once the packages are installed, you can move on to the next step. Install the pre-requisite packages necessary for building Redis using the following yum command: yum install gcc make wget tcl
Let’s begin with the installation.Ĭonnect to your CentOS server via SSH and upgrade the installed packages to the newest versions by typing: yum update
The Redis package that is included in the default CentOS repositories is pretty outdated, so installing from the source code will ensure that we have the latest version of Redis installed on our system. Redis supports different kinds of abstract data structures such as strings, lists, maps, sets, sorted sets, hyper logs, bitmaps, and spatial indexes. Redis is an in-memory data structure store primarily used as a database and cache. You can follow the idea behind it if you have old Centos 6 version or you have Latest Centos7 and cPanel/WHM versions.In this tutorial, we are going to build and install Redis on our CentOS 7 Cloud VPS from source. Which doesn’t mean that you need exact same environment. Below is the system environment I used for testing. So if you don’t have a root access to the server, get it before proceed further.
To complete the installation steps below you will need root access to your server. The Redis daemon and Redis PHP Extension is the one we need to install. Additionally if a page or blog post edited, the Redis cache for that content will be invalidated and will the updated content after the next refresh of page. Advantage of RedisĬaching with Redis will not have the need to manually flush the cache when new content is published. This is achieved by storing the query results as memory blocks. Redis provides an alternative caching back-end, taking that work off the database, which is vital for scaling to a larger number of logged-in users. Since the database also handles many queries for normal page requests, it is the most common bottleneck causing increase load-times. Most website frameworks like WordPress use the database to cache internal application “objects” which can be expensive to generate (menu trees, filter results, etc.), and to keep cached page content. If you liked it you can also purchase it from their below url. Today we discuss further on it.īefore proceed with the installation method we follow, I would also like to mention one point as, I have noticed, there is a third party plugin exists for Redis cache developed by a company named. We need to install the Redis caching server manually on a cPanel based server. There is no in house option like cPanel Redis plugin at this moment. Normally Webmasters use Redis as caching module and there by improve the site loading time of websites.
Its up to you which one you would like to use and what kind of configuration setup better suits your environment. If you a question in mind like which Caching system is best Memcache or Redis, I would say its hard to tell, Both caching systems have their own Advantages. Redis is an open source, in-memory data structure store, used as a database, cache and message broker that can be used as a drop-in caching back-end for your Drupal or WordPress website.
