technique

redis_cluster

on the same server

based on redis 5.0.0
https://my.oschina.net/ruoli/blog/2252393

  1. create dir /root/software/redis

  2. download the source code and compile

    1
    2
    3
    4
    ​wget http://download.redis.io/releases/redis-5.0.0.tar.gz
    tar xzf redis-5.0.0.tar.gz
    cd redis-5.0.0
    make

  3. create 6 redis.conf for the cluster

    1

    3
    4
    5
    6
    /root/software/redis/redis-cluster-conf/7001/redis.conf
    /root/software/redis/redis-cluster-conf/7002/redis.conf
    /root/software/redis/redis-cluster-conf/7003/redis.conf
    /root/software/redis/redis-cluster-conf/7004/redis.conf
    /root/software/redis/redis-cluster-conf/7005/redis.conf
    /root/software/redis/redis-cluster-conf/7006/redis.conf

the conf of the 1st node as below:

1
2
3
4
5
6
7
8
port 7001  #端口
cluster-enabled yes #启用集群模式
cluster-config-file nodes.conf
cluster-node-timeout 5000 #超时时间
appendonly yes
daemonize yes #后台运行
protected-mode no #非保护模式
pidfile  /var/run/redis_7001.pid

NOTE: the port and pidfile SHOULD BE 7001/7002/…, redis_7001.pid/redis_7002.pid/…

  1. startup 6 nodes

    1

    /root/software/redis/redis-5.0.0/src/redis-server  /root/software/redis/redis-cluster-conf/7001/redis.conf
    /root/software/redis/redis-5.0.0/src/redis-server  /root/software/redis/redis-cluster-conf/7002/redis.conf
    /root/software/redis/redis-5.0.0/src/redis-server  /root/software/redis/redis-cluster-conf/7003/redis.conf
    /root/software/redis/redis-5.0.0/src/redis-server  /root/software/redis/redis-cluster-conf/7004/redis.conf
    /root/software/redis/redis-5.0.0/src/redis-server  /root/software/redis/redis-cluster-conf/7005/redis.conf
    /root/software/redis/redis-5.0.0/src/redis-server  /root/software/redis/redis-cluster-conf/7006/redis.conf

  2. startup the cluster

    1
    2
    # DO REMEMBER update the ip to your ip
    /root/software/redis/redis-5.0.0/src/redis-cli --cluster create 192.168.2.40:7001 192.168.2.40:7002 192.168.2.40:7003 192.168.2.40:7004 192.168.2.40:7005 192.168.2.40:7006 --cluster-replicas 1

on 6 servers
