Also, you should replace \u2018root\u2019 with the username of the admin account if needed.<\/p>\n\n\n\n<p>Once you are in, run the following commands to update the package index and upgrade all installed packages to the latest available version<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo apt-get update \nsudo apt-get upgrade<\/pre>\n\n\n\n<p>Once the upgrades are completed, we can move on to the next step.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-2-install-redis-on-ubuntu-20-04\"><span class=\"ez-toc-section\" id=\"2-Install-Redis-on-Ubuntu-2004\"><\/span>2. Install Redis on Ubuntu 20.04<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>When an update is completed, you will download and install it from the official Ubuntu repositories. Redis version 5.0.x is included by default on Ubuntu 20.04 repositories.<\/p>\n\n\n\n<p>Run the following command to install Redis on your server:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo apt-get install redis-server<\/pre>\n\n\n\n<p>With this command, you will also download and install all the required dependencies.<\/p>\n\n\n\n<p>Once the installation is completed, the Redis service will start automatically. To check and verify the status of your Redis service, run the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo systemctl status redis-server<\/pre>\n\n\n\n<p>You should receive the following output:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">\u25cf redis-server.service - Advanced key-value store\nLoaded: loaded (\/lib\/systemd\/system\/redis-server.service; enabled; vendor preset: enabled)\nActive: active (running) since Sat 2021-09-25 11:01:30 UTC; 12min ago\nDocs: http:\/\/redis.io\/documentation,\nman:redis-server(1)\nMain PID: 199086 (redis-server)\nTasks: 4 (limit: 2279)\nMemory: 2.0M\nCGroup: \/system.slice\/redis-server.service\n\u2514\u2500199086 \/usr\/bin\/redis-server 127.0.0.1:6379<\/pre>\n\n\n\n<p>The default port of Redis is <code>6379<\/code> and IP <code>127.0.0.1<\/code> is localhost.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-3-check-redis-version\"><span class=\"ez-toc-section\" id=\"3-Check-Redis-Version\"><\/span>3.

How to configure Redis server<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Redis can start without a configuration file using a built-in default configuration. Now you need to make one important configuration change in Redis. Open the Redis config, <code>redis.conf<\/code> with your favorite editor. We will use nano. You are free to use any other text editor if you prefer:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo nano \/etc\/redis\/redis.conf<\/pre>\n\n\n\n<p>You need to find a <em>supervised<\/em> directive. By default, this line is set to <code>no<\/code>. However, to manage Redis as a service you will change it to <code>systemd<\/code>.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\"># If you run Redis from upstart or systemd, Redis can interact with your\n# supervision tree. Options:\n# supervised no - no supervision interaction\n# supervised upstart - signal upstart by putting Redis into SIGSTOP mode\n# supervised systemd - signal systemd by writing READY=1 to $NOTIFY_SOCKET\n# supervised auto - detect upstart or systemd method based on\n# UPSTART_JOB or NOTIFY_SOCKET environment variables\n# Note: these supervision methods only signal \"process is ready.\"\n# They do not enable continuous liveness pings back to your supervisor.\nsupervised systemd<\/pre>\n\n\n\n<p>To make Redis aware of this, you need to restart it with the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo systemctl restart redis-server<\/pre>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-5-check-redis-connection\"><span class=\"ez-toc-section\" id=\"5-Check-Redis-Connection\"><\/span>5.

To connect with this command-line client, enter the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">redis-cli<\/pre>\n\n\n\n<p>To test the connectivity, run:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">ping<\/pre>\n\n\n\n<p>The output should respond with:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">PONG<\/pre>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-6-managing-the-redis-service\"><span class=\"ez-toc-section\" id=\"6-Managing-the-Redis-Service\"><\/span>6: Managing the Redis Service<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>To <strong>stop<\/strong> your service, run the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo systemctl stop redis-server<\/pre>\n\n\n\n<p>To <strong>start<\/strong> your service, run the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo systemctl start redis-server<\/pre>\n\n\n\n<p>To <strong>enable<\/strong> your service, run the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo systemctl enable redis-server<\/pre>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-7-how-to-secure-redis\"><span class=\"ez-toc-section\" id=\"7-How-to-Secure-Redis\"><\/span>7.

To enable the password authentication, open the Redis configuration file:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo nano \/etc\/redis\/redis.conf<\/pre>\n\n\n\n<p>Scrolling through the file, there will be a section called <em>SECURITY<\/em> , where this entry will be shown:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\"># requirepass foobared<\/pre>\n\n\n\n<p>and replace <code>foobared<\/code> with the password of your choice.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">requirepass your_strong_password<\/pre>\n\n\n\n<p><strong>Note:<\/strong> Do not forget to uncomment and change <code>your_strong_password<\/code> with your strong password.<\/p>\n\n\n\n<p>And restart the Redis service for the changes to take effect.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo systemctl restart redis.service<\/pre>\n\n\n\n<p>Now the password authentication for Redis has been enabled.<\/p>\n\n\n\n<p>To test that the password works, open up the Redis client:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">redis-cli<\/pre>\n\n\n\n<p>Once you&#8217;re connected to the server, try the ping with the following command.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">ping \"hello world\"<\/pre>\n\n\n\n<p>Now you will get the result as below.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"550\" height=\"49\" src=\"https:\/\/www.rosehosting.com\/blog\/wp-content\/uploads\/2021\/10\/installing-and-securing-redis-on-ubuntu-20.04.jpg\" alt=\"installing and securing redis on ubuntu 20.04\" class=\"wp-image-39281\" srcset=\"https:\/\/www.rosehosting.com\/blog\/wp-content\/uploads\/2021\/10\/installing-and-securing-redis-on-ubuntu-20.04.jpg 550w, https:\/\/www.rosehosting.com\/blog\/wp-content\/uploads\/2021\/10\/installing-and-securing-redis-on-ubuntu-20.04-300x27.jpg 300w, https:\/\/www.rosehosting.com\/blog\/wp-content\/uploads\/2021\/10\/installing-and-securing-redis-on-ubuntu-20.04-150x13.jpg 150w\" sizes=\"(max-width: 550px) 100vw, 550px\" \/><\/figure>\n\n\n\n<p>To authenticate, just use the <em>auth<\/em> command, as shown below:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">auth your_strong_password<\/pre>\n\n\n\n<p>Below is the result after you&#8217;re authenticated to the Redis Server.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"550\" height=\"93\" src=\"https:\/\/www.rosehosting.com\/blog\/wp-content\/uploads\/2021\/10\/installation-and-securing-redus-on-an-ubuntu-20.04.jpg\" alt=\"installation and securing redus on an ubuntu 20.04\" class=\"wp-image-39282\" srcset=\"https:\/\/www.rosehosting.com\/blog\/wp-content\/uploads\/2021\/10\/installation-and-securing-redus-on-an-ubuntu-20.04.jpg 550w, https:\/\/www.rosehosting.com\/blog\/wp-content\/uploads\/2021\/10\/installation-and-securing-redus-on-an-ubuntu-20.04-300x51.jpg 300w, https:\/\/www.rosehosting.com\/blog\/wp-content\/uploads\/2021\/10\/installation-and-securing-redus-on-an-ubuntu-20.04-150x25.jpg 150w\" sizes=\"(max-width: 550px) 100vw, 550px\" \/><\/figure>\n\n\n\n<p>That\u2019s it!
