2.3クラスタ構築

2.3.1基礎クラスタ

mkdri redis-cluster
cd redis-cluster
mkdir 7000/7001/7002/7003/7004/7005
cp ../redis.conf ./7000/7001/7002/7003/7004/7005

**    **
Vim redis.conf
port 7000 #7001/7002/7003/7004/7005
# bind 127.0.0.1 ::1
protect-mode no
daemonize yes
pidfile /var/run/redis_7000.pid
cluster-enabled yes
cluster-config-file nodes-7000.conf
cluster-node-timeout 15000
appendonly  yes 

**    **
../../src/redis-server redis.conf

2.3.2クラスタ負荷主従構築

  ruby
yum -y install ruby ruby-devel rubygems rpm-build
  gem-redis
gem install redis-3.2.2.gem
    
redis-trib.rb  create  --replicas  1  111.231.112.x:7000 111.231.112.x:7001  111.231.112.x:7002 111.231.112.x:7003  111.231.112.x:7004  111.231.112.x:7005

[OK] All nodes agree about slots configuration.

>>> Check slots coverage...
[OK] All 16384 slots covered.

クラスタテスト:

Master 7000 
[root@VM_0_7_centos ~]# redis-cli -c -p 7000
127.0.0.1:7000> set y dsfsdfsdf
-> Redirected to slot [12222] located at 111.231.112.151:7002

Master 7002
[root@VM_0_7_centos ~]# redis-cli -h 127.0.0.1 -c -p 7002
127.0.0.1:7002> set hello world
-> Redirected to slot [866] located at 111.231.112.151:7000
OK
Salve 7004
[root@VM_0_7_centos ~]# redis-cli -c -p 7004
127.0.0.1:7004> set k dsadfadsfa
-> Redirected to slot [7629] located at 111.231.112.151:7001
OK

まとめ:

1)7000 master->7003 replica,7001 master->7004 replica,7002 master->7005 slave

2)ノード負荷等化、主書き込み動作、読み出し動作
