Redis The cluster is required to at least 6 Nodes , And it has to be 3 Above version
If it is a lower version, it may appear ruby In the case of low version

Redis Cluster installation _redis

Operation user

root

Start installation

Pass the installation package through sftp Or client tools or rz Command and other methods to upload to /root Under the table of contents
Execute the decompression command and extract to /usr/local Under the table of contents
```
tar -zxvf redis-3.2.1.tar.gz -C /usr/local

       
        1.
       
```
Enter the decompression directory and execute the compilation command ( The installation of the compilation environment will not be repeated here )
```
make

       
        1.
       
```

stay redis Execute the command to create 6 individual Redis The configuration file

mkdir {6379,6380,6381,6382,6383,6384}

touch {6379/redis.conf,6380/redis.conf,6381/redis.conf,6382/redis.conf,6383/redis.conf,6384/redis.conf}

       
        1.
        2.
        3.

Configure the contents of the configuration file separately as ( The configuration files of different ports configure different ports )

daemonize    yes                          //redis Background operation 
pidfile  /var/run/redis_6379.pid
port  6379
cluster-enabled  yes                      // Open clusters    Put the notes # Get rid of 
cluster-config-file  nodes_6379.conf      // Configuration of cluster    The configuration file is automatically generated for the first time 
cluster-node-timeout  5000                // request timeout    Set up 5 Seconds is enough 
appendonly  yes                           //aof Log on    Turn it on if you need it ,

It will record a log every time it writes port and pidfile Need to follow Different increments of folders .

Enter into redis Unzip directory , Execute the command to start each node

./src/redis-server /usr/local/redis-5.0.0/6379/redis.conf
./src/redis-server /usr/local/redis-5.0.0/6380/redis.conf
./src/redis-server /usr/local/redis-5.0.0/6381/redis.conf
./src/redis-server /usr/local/redis-5.0.0/6382/redis.conf
./src/redis-server /usr/local/redis-5.0.0/6383/redis.conf
./src/redis-server /usr/local/redis-5.0.0/6384/redis.conf

        3.
        4.
        5.
        6.

Check each node redis process

Create a cluster client

./src/redis-cli --cluster create 192.168.5.57:6379 192.168.5.57:6380 192.168.5.57:6381 192.168.5.57:6382 192.168.5.57:6383 192.168.5.57:6384 --cluster-replicas 1

The above figure shows that the startup is successful , You can see three master Three stations slave !

Shutting down the cluster is not repeated here , A little violence directly kills the process , For other ways, please refer to the link https://my.oschina.net/ruoli/blog/2252393
