We start with this section with a very important tool, Docker Compose, which is used frequently. Let's start with a case study of why we use Docker Compose. Case study: How do I deploy a WordPress via a container? Now pull WordPress locally: docker pull wordpress docker image ls REPOSITORY TAG IMAGE ID ...

1. Node planning: Two ways: one master + many slaves, many to many slaves, the second way to share the master node, easy to expand and reduce capacity. Container name container IP address Map port number Service Running Mode Redis-master1 172.1.50.11 6391->6379,16391->6379 master ...

This is a simple story of data production import, the original story should be as follows: data collation - > test verification - > production release - > production verification, and then back to home, so this should be a plain story, but in fact it has become the following plot: data collation - > test verification - > producti ...

Redis provides a list, hash, zset and other complex types of data structures. When business is used, a key may be too large due to unreasonable key design. Because redis is a simple single-threaded model, business will have a certain impact on the acquisition or deletion of large keys. In addition, in cluster mode, the generation of large keys ...

Docker Network Model Docker has multiple network modes, including host, none,bridge Overay and so on. Next, we discuss the relationship between Docker network and iptables with Docker's default bridge network, Docker 0. Docker 0 network is a virtual bridge network built by Docker. The default gateway address is 172.17.0.1. Docker's default net ...

Introduction to Redis Cluster: The Redis cluster is a distributed implementation with the following goals, sorted by design importance: * High performance and linear scalability of up to 1000 nodes.There is no proxy, asynchronous replication is used, and there is no merge when assigning values. *Acceptable write security: When a clien ...

1. The process of redis master-slave replication synchronization 1. Send a sync synchronization command from the service to the primary service to require full synchronization 2. When the primary service receives sync synchronization commands from the service, a subprocess of fork executes bgsave command (non-blocking) snapshot saving in the ...

SETNX is an instruction in Redis, called "Set If Not Exist", which sets value to key only when it does not exist, otherwise no operation is performed. SETNX can also be used to implement locks in Redis. Problem introduction Before introducing how to use SETNX to implement locks, let's consider the following question: Suppose we now ha ...
