redis三主三従配置

サーバA:192.168.3.188 centos 7サーバB:192.168.3.189 centos 7 firewalldファイアウォールを閉じ、selinuxを閉じます.redisバージョン4.0.1、少なくとも6台はredis clusterをします

yum -y install wget vim tcl gcc make
mkdir –p /usr/local/redis
cd !$
wget http://download.redis.io/releases/redis-4.0.1.tar.gz
tar –xvf redis-4.0.1.tar.gz
make
make test-

  redis       
cp -a src/redis-server src/redis-cli src/redis-sentinel src/redis-trib.rb src/redis-check-aof src/redis-check-rdb src/redis-benchmark /usr/local/bin/
mkdir cluster-redis
cd cluster-redis
mkdir {7000,7001,7002}

他のredisプロファイルは、対応するポートとデータベース名を変更すればよいので、redisを順次起動します.

redis-server /usr/local/redis/cluster-redis/7000/redis.conf
redis-server /usr/local/redis/cluster-redis/7001/redis.conf
redis-server /usr/local/redis/cluster-redis/7002/redis.conf——           redis  

次の2つの依存関係、zlibとopensslを事前にインストールします.

yum -y install zlib-devel
yum install openssl-devel -y
   ruby，ruby-2.3.4.tar.gz，       
./configure
Make && make install
Ruby –v    2.2.2  

redisをインストールし、インストールできない場合はgemソースを切り替え、次のリンクを見てgemソースを交換します.https://ruby.taobao.org/

Gem install redis

クラスタの起動

redis-trib.rb create --replicas 1 192.168.3.188:7000 192.168.3.188:7001 192.168.3.188:7002 192.168.3.189:7000 192.168.3.189:7001 192.168.3.189:7002

あるノードにログイン

redis-cli 192.168.3.188 -c -p 7001
