配置redis cluster，以两台机器，6个实例为环境。
操作系统 CentOS Linux release 7 64位
安装依赖包：单独下载redis-3.3.1.gem这个包要对应os版本
yum -y install tcl yum -y install ruby ruby-devel rubygems rpm-build gem install redis
解压安装：
cd /usr/local/ tar zxvf redis-3.2.3.tar.gz cd redis-3.2.3 make && make install
在172.16.25.220的/usr/local/webapp下创建bin、redis6379、redis6380、redis6381四个目录
mkdir bin mkdir redis6379 mkdir redis6380 mkdir redis6381
在172.16.25.72的/usr/local/webapp下创建bin、redis6379、redis6380、redis6381四个目录
mkdir bin mkdir redis6379 mkdir redis6380 mkdir redis6381
分别在两台机器上创建配置文件，并启动：
cd /usr/local/redis-3.2.3/src/ cp mkreleasehdr.sh redis-benchmark redis-sentinel redis-server redis-trib.rb redis-cli /usr/local/webapp/bin cd /usr/local/webapp/redis6379/ touch redis-6379.conf cp /usr/local/webapp/redis6379/redis-6379.conf /usr/local/webapp/redis6380/redis-6380.conf cp /usr/local/webapp/redis6379/redis-6379.conf /usr/local/webapp/redis6381/redis-6381.conf sed -i ‘s/6379/6380/g‘ /usr/local/webapp/redis6380/redis-6380.conf sed -i ‘s/6379/6381/g‘ /usr/local/webapp/redis6381/redis-6381.conf /usr/local/webapp/bin/redis-server /usr/local/webapp/redis6379/redis-6379.conf /usr/local/webapp/bin/redis-server /usr/local/webapp/redis6380/redis-6380.conf /usr/local/webapp/bin/redis-server /usr/local/webapp/redis6381/redis-6381.conf
创建集群（在其中一台服务器上执行即可）
cd /usr/local/webapp/bin/ ./redis-trib.rb create --replicas 1 172.16.25.220:6379 172.16.25.72:6379 172.16.25.220:6380 172.16.25.72:6380 172.16.25.220:6381 172.16.25.72:6381
集群状态查看：

给redis cluster集群加上认证功能：
登陆集群后配置密码（我这里测试不生效） ./redis-cli -c -h 172.16.25.72 -p 6379 config set masterauth mypasswd config set requirepass mypasswd config rewrite 修改配置文件：加入下面两行 requirepass "mypasswd" masterauth "mypasswd" 停redis ./redis-cli -c -h 172.16.25.220 -p 6379 shutdown ./redis-cli -c -h 172.16.25.220 -p 6380 shutdown ./redis-cli -c -h 172.16.25.220 -p 6381 shutdown ./redis-cli -c -h 172.16.25.72 -p 6381 shutdown ./redis-cli -c -h 172.16.25.72 -p 6380 shutdown ./redis-cli -c -h 172.16.25.72 -p 6379 shutdown 修改 修改gem的redis工具下的一个文件，我这里是默认安装，路径如下：/usr/local/share/gems/gems/redis-3.3.1/lib/redis/client.rb vim /usr/local/share/gems/gems/redis-3.3.1/lib/redis/client.rb 启动redis service redis6379 start service redis6380 start service redis6381 start 登陆 ./redis-cli -c -h 172.16.25.220 -p 6380 172.16.25.220:6380> cluster nodes NOAUTH Authentication required. 172.16.25.220:6380> auth mypasswd OK 172.16.25.220:6380> cluster nodes 3b64702727c2e047f255ebb6eb111359990fba85 172.16.25.72:6379 master - 0 1478249211338 2 connected 5461-10922 a0ac9b45dd7bfabeb7036278c13efb744794adc8 172.16.25.72:6380 master - 0 1478249211839 7 connected 0-5460 f612b1d6e362c52ac606a627bcc27a95224ce2b3 172.16.25.220:6381 slave 3b64702727c2e047f255ebb6eb111359990fba85 0 1478249210836 5 connected 954200fe3b22806af5afc035cdf0a25899c14ecd 172.16.25.220:6380 myself,slave ca66b71a3e2b7bf75885720b4c7bd3015dd732a1 0 0 3 connected ca66b71a3e2b7bf75885720b4c7bd3015dd732a1 172.16.25.72:6381 master - 0 1478249212341 8 connected 10923-16383 2b2b3a1885a9a2b64060b20322d3c425b64ca063 172.16.25.220:6379 slave a0ac9b45dd7bfabeb7036278c13efb744794adc8 0 1478249210334 7 connected 172.16.25.220:6380> ./redis-cli -c -h 172.16.25.220 -p 6380 -a mypasswd 172.16.25.220:6380> cluster nodes 3b64702727c2e047f255ebb6eb111359990fba85 172.16.25.72:6379 master - 0 1478249255421 2 connected 5461-10922 a0ac9b45dd7bfabeb7036278c13efb744794adc8 172.16.25.72:6380 master - 0 1478249256423 7 connected 0-5460 f612b1d6e362c52ac606a627bcc27a95224ce2b3 172.16.25.220:6381 slave 3b64702727c2e047f255ebb6eb111359990fba85 0 1478249254919 5 connected 954200fe3b22806af5afc035cdf0a25899c14ecd 172.16.25.220:6380 myself,slave ca66b71a3e2b7bf75885720b4c7bd3015dd732a1 0 0 3 connected ca66b71a3e2b7bf75885720b4c7bd3015dd732a1 172.16.25.72:6381 master - 0 1478249254419 8 connected 10923-16383 2b2b3a1885a9a2b64060b20322d3c425b64ca063 172.16.25.220:6379 slave a0ac9b45dd7bfabeb7036278c13efb744794adc8 0 1478249255921 7 connected 172.16.25.220:6380> 停止有密码认证的集群 ./redis-cli -c -a "mypasswd" -h 172.16.25.220 -p 6379 shutdown
配置自启动：
如果配置成自启动，那相关的权限会变成root权限，请慎重考虑。下面给出自启动的脚本，仅供参考。
在/etc/init.d下编写脚本redis6379，并给+x权限，然后配置启动级别
chkconfig --add redis6379
chkconfig --level 345 redis6379 on
脚本如下：
cat /etc/init.d/redis6379
#!/bin/bash
#chkconfig:345 61 61
PATH=/usr/local/bin:/sbin:/usr/bin:/bin
REDISPORT=6379
