redis叢集安裝
下載安裝redis(所有節點)
wget tar zxvf redis-4.0.11.tar.gzcd redis-4.0.11 makecd src/ make install
配置redis

sed -i 's/10.241.0.10/10.241.0.12/g' /usr/local/redis-cluster/7001/redis.conf
啟動redis(所有節點)
/usr/local/redis-cluster/bin/redis-server /usr/local/redis-cluster/7000/redis.conf /usr/local/redis-cluster/bin/redis-server /usr/local/redis-cluster/7001/redis.conf ps -ef|grep redis root 3079 1 0 00:26 ? 00:00:00 /usr/local/redis-cluster/bin/redis-server 10.241.0.10:7000 [cluster] root 3243 1 0 00:28 ? 00:00:00 /usr/local/redis-cluster/bin/redis-server 10.241.0.10:7001 [cluster] netstat -nplt|grep redis-server tcp 0 0 10.241.0.10:17000 0.0.0.0:* LISTEN 3243/redis-server 1 tcp 0 0 10.241.0.10:17001 0.0.0.0:* LISTEN 3079/redis-server 1 tcp 0 0 10.241.0.10:7000 0.0.0.0:* LISTEN 3243/redis-server 1 tcp 0 0 10.241.0.10:7001 0.0.0.0:* LISTEN 3079/redis-server 1
iptables放行
#如開iptables,需注意,埠放行, 注意17000,17001也要放行,不然加入不到叢集-A INPUT -p tcp -m tcp --dport 7000 -j ACCEPT -A INPUT -p tcp -m tcp --dport 7001 -j ACCEPT -A INPUT -p tcp -m tcp --dport 17000 -j ACCEPT -A INPUT -p tcp -m tcp --dport 17001 -j ACCEPT
配置叢集(只在node1操作)
安裝ruby
wget tar xvf ruby-2.2.7.tar.gzcd ruby-2.2.7 ./configure --prefix=/usr/local/ruby-2.2.7 make && make install ln -s /usr/local/ruby-2.2.7/bin/ruby /usr/bin/ruby ln -s /usr/local/ruby-2.2.7/bin/gem /usr/bin ruby -v gem -v
使用gem安裝redis叢集依賴
gem install redis
建立叢集
如叢集都設定了密碼,需要修該 /usr/local/ruby-2.2.7/lib/ruby/gems/2.2.0/gems/redis-4.0.1/lib/redis/client.rb 檔案中的 Password 引數將密碼寫入到這裡,
