![]() ![]() Restarting Redis Server with Configuration File If the server is running properly, the output should show that the server is up and running. This will display information about the server, such as the version, the number of connected clients, and the number of keys stored in the server. This can be done by running the command “redis- cli info”. Once the Redis server has been restarted, it is important to check the status of the server to make sure that it is running properly. This will start the server and all of its processes. This can be done by running the command “redis-server”. Once the server has been stopped, the next step is to start the server again. This will stop the server and all of its processes. This can be done by running the command “redis- cli shutdown”. The first step to restarting a Redis server is to stop the server. In this article, we will discuss how to restart a Redis server. Restarting a Redis server can be done to fix any issues that may be occurring with the server, or to apply any changes that have been made to the server. It is used to store and retrieve data from memory, making it faster than traditional databases. ![]() Redis is an open source, in- memory data structure store used as a database, cache, and message broker. If the client connects to another replica node in the same or different shard, then you might need to issue a new readonly command.Restarting a Redis server is a simple process that can be done in a few steps. The command is active only until the client reads keys from the same node. ![]() The readonly command needs to be issued when the client connects to a node for the first time. In the following example, the readonly command is sent first, so the replica node processes the request instead of redirecting it to a primary node. For more information about the MOVED error, refer to Redis cluster specification - Redirection and resharding on the Redis.io website. Note: The MOVED error shown in the preceding example occurs when the Redis cluster client isn't cluster aware and can't handle redirection requests to the primary node. In the following example, the readonly command isn't sent, and the request is redirected to a primary node. Otherwise, the request is redirected to the primary node of the shard that the hash slot belongs to.ġ. This means that the replica node processes the request only if readonly is issued by the client before the request. The replica node serves the read request only if that shard belongs to the hash slot and a readonly command is initiated by the client. The default behavior of replica nodes in cluster-mode enabled clusters is to redirect all client read/write requests to an authoritative primary node of the shard that belongs to the key's hash slot. When a client sends a read/write query to a replica node, the node analyzes the request to confirm whether it is a single key or multi-key operation that belongs to the same hash slot of the shard. Any node in a Redis cluster can receive queries from Redis clients. ![]()
