Redis Standalone Open Multi-instance

This article mainly introduces the Redis single-use open multi-instance, has a certain reference value, now share to everyone, the need for friends can refer to

Redis is an open-source (BSD-licensed), in-memory data structure storage system that can be used as a database, cache, and message middleware. It supports multiple types of data structures such as string (strings), hash (hashes), list (lists), set (sets), ordered set (sorted sets) with Range query, bitmaps, hyperloglogs and geo-spatial (geospatial) Index RADIUS query. Redis has built-in replication (replication), LUA scripting (LUA scripting), LRU driver events (LRU eviction), transactions (transactions), and different levels of disk persistence (persistence), and Redis Sentinel (Sentinel) and automatic partitioning (Cluster) provide high availability (HI availability).

Single-Machine multi-instance Setup

Redis supports running multiple instances on the same host to serve different purposes.
Distinguished by an open port number, the default port is 6379, and the configuration file path is:
/etc/redis/redis.conf
If you plan to open a new instance using port 6581, copy a configuration file and rename it to redis-6581.conf
Modify the port-related configuration inside:

Port 6581pidfile/var/run/redis/redis-server-6581.pidunixsocket/var/run/redis/redis-6581.socklogfile/var/log/ Redis/redis-server-6581.logdbfilename Dump-6581.rdb

It should be noted that Redis users should normally be used to start the Redis service, which means that the directory permissions involved in the above configuration file need to be assigned to Redis users.

The command to start a new service using a Redis user is:

# su-l Redis--shell=/bin/bash-c '/usr/bin/redis-server/etc/redis/redis-6581.conf '

The following is a sample configuration file:

# su-l Redis--shell=/bin/bash-c '/usr/bin/redis-server/etc/redis/redis-6581.conf ' daemonize Yes
