1. Environmental description

Redis will not be introduced in detail in this article. Friends who don't know much about redis can refer to this link http://www.runoob.com/redis/redis-tutorial.html.

At least 3 master nodes are required for the redis cluster to work properly. Here, we need to create 6 redis nodes, of which three are master nodes and three are slave nodes. The ip and port correspondence of the corresponding redis nodes are as follows:

Host and port 192.168.102.51, 192.168.102.51, 6380192.168.102.52, 192.168.102.52, 192.168.102.53, 192.168.102.53, 192.168.102.53

Description: 3 servers deploy redis cluster environment, if you are only used for test deployment, you can configure it on 1 server, but do not repeat the port.

2. Prepare redis-related dependency packages

(all three servers need to be installed)

3. Install redis (all three servers need to be installed)

Decompress, compile

# tar-zxvf redis-3.2.3.tar.gz

# cd redis-3.2.3

# make

Create a directory required for redis

# mkdir-p / usr/local/redis/ {bin,conf,data,logs} # # create redis related directories

# cp src/redis-server / usr/local/redis/bin/ # # daemon launcher for Redis server

# cp src/redis-cli / usr/local/redis/bin/ # # Redis command line operation tool

# cp src/redis-trib.rb / usr/local/redis/bin/ # # Redis Cluster tool

# cp src/redis-benchmark / usr/local/redis/bin/ # # Redis performance testing tool

# cp src/redis-check-aof / usr/local/redis/bin/ # # repair corrupted aof files

# cp src/redis-check-dump / usr/local/redis/bin/ # # check the export utility

# cp src/redis-sentinel / usr/local/redis/bin/ # # Redis cluster management tools

Note: if you do not want to operate as troublesome as above, you can also directly copy all the files in the src directory to / usr/local/redis/bin/

For example: cp src/* / usr/local/redis/bin/

Copy the redis configuration file

# cp redis.conf / usr/local/redis/conf/redis-6379.conf

# cp redis.conf / usr/local/redis/conf/redis-6380.conf

Modify redis configuration file (modify red font section)

Bind 0.0.0.0 # address that the redis service listens to

Protected-mode yes

Port 6379 # if it is a redis-6380.conf configuration file, modify it to 6380

Tcp-backlog 511

Tcp-keepalive 300

Change daemonize yes # to yes and let redis run in the background

Supervised no

Pidfile / var/run/redis_6379.pid # if it is a redis-6380.conf configuration file, modify it to redis_6380.pid

Loglevel notice

Logfile / usr/local/redis/logs/redis-6379.log # if it is a redis-6380.conf configuration file, modify it to redis_6380.pid

The configuration of cluster-config-file nodes-51-6379.conf # needs to be explained in particular.

It is important to note that it is best not to use the same name for the configuration of these three servers. It is recommended to choose the name in the following way (of course, you can specify it yourself):

192.168.102.51:nodes-51-6379.conf nodes-51-6380.conf

192.168.102.52:nodes-52-6379.conf nodes-52-6380.conf

192.168.102.53:nodes-53-6379.conf nodes-53-6380.conf

4. Start the redis cluster

4.1 start redis instances (start 6379 first, then start 6380) one by one:

# / usr/local/redis/bin/redis-server / usr/local/redis/conf/redis-6379.conf # start 6379 instances of these three servers in phase order

# / usr/local/redis/bin/redis-server / usr/local/redis/conf/redis-6380.conf # launch 6380 instances of three servers in phase order

Then check whether the instance starts normally:

# ps-ef | grep redis

Create a cluster (on the first redis server and execute the following command)

# / usr/local/redis/bin//bin/redis-trib.rb create-- replicas 1 192.168.102.51 192.168.102.53:6380Can I set the above configuration 6379 192.168.102.52 192.168.102.53:6380Can I set the above configuration 6379 192.168.102.53 192.168.102.53:6380Can I set the above configuration? (type 'yes' to accept): yes # enter yes here
