What to do if redis-server can't be found

Steps to solve the problem that redis-server cannot find: Check the installation to make sure Redis is installed correctly; set the environment variables REDIS_HOST and REDIS_PORT; start the Redis server redis-server; check whether the server is running redis-cli ping.

Redis-server not found solution

A common reason why redis-server cannot be found may be because it is not installed correctly or environment variables are not set. Here are the steps to resolve this issue:

Check the installation

• Make sure Redis is installed correctly. Check the Redis installation directory, usually located in /usr/local/bin/redis-server .
• If not installed, download and install it according to your operating system and Redis version.

Set environment variables

Redis requires the environment variables REDIS_PORT and REDIS_HOST to run. Make sure the following environment variables are set:

• REDIS_HOST : The IP address or host name of the Redis server (such as localhost )
• REDIS_PORT : The port of the Redis server (default is 6379)

You can set environment variables using the following command:

 <code class="bash">export REDIS_HOST=localhost export REDIS_PORT=6379</code>

Start Redis Server

After completing these steps, you can start the Redis server:

 <code class="bash">redis-server</code>

After starting the Redis server, you can check if it is running using the following command:

 <code class="bash">redis-cli ping</code>

If the output is "PONG", the Redis server is running normally.
