1.安装redis 3.0.1，参见
2.创建目录
| 1 | mkdir -p /usr/local/redis/7000 |
3.复制文件
| 1 2 3 4 5 | cd /tmp #复制默认的配置文档 cp redis-3.0.1 /redis .conf /usr/local/redis/redis .default.conf #把编译好的server复制到运行目录 cp redis-3.0.1 /src/redis-server /usr/local/redis/7000/ |
4.建立独立配置文件
| 1 2 | #在7000目录下建立redis的配置文档 vim /usr/local/redis/7000/redis .conf |
| 1 2 3 4 5 6 7 8 | #/usr/local/redis/7000/redis.conf include /usr/local/redis/redis.default.conf pidfile /var/run/redis-7000.pid port 7000 cluster-enabled yes cluster-config-file redis-node-7000.conf cluster-node-timeout 5000 appendonly yes |
5.复制运行目录
| 1 2 3 4 5 6 | cd /usr/local/redis/ cp -R 7000/ 7001/ cp -R 7000/ 7002/ cp -R 7000/ 7003/ cp -R 7000/ 7004/ cp -R 7000/ 7005/ |
6.修改相应配置文件的端口和文件名
7.建立启动脚本/usr/local/redis/redis-start.sh
| 1 2 3 4 5 6 7 | #!/bin/sh /usr/local/redis/7000/redis-server /usr/local/redis/7000/redis .conf & /usr/local/redis/7001/redis-server /usr/local/redis/7001/redis .conf & /usr/local/redis/7002/redis-server /usr/local/redis/7002/redis .conf & /usr/local/redis/7003/redis-server /usr/local/redis/7003/redis .conf & /usr/local/redis/7004/redis-server /usr/local/redis/7004/redis .conf & /usr/local/redis/7005/redis-server /usr/local/redis/7005/redis .conf & |
8.添加执行权限
| 1 | chmod a+x redis-start.sh |
9.启动六个redis实例
| 1 | . /redis-start .sh |
配置集群
1.安装ruby
| 1 | yum install ruby-devel.x86_64 |
2.安装redis gem
| 1 | gem install redis |
3.使用脚本建立集群机制
在create的时候,加上参数--replicas 1 表示为每个master分配一个salve,如例子,则是3个master 3个salve
| 1 2 | cd /tmp/redis-3 .0.1 /src/ . /redis-trib .rb create --replicas 1 127.0.0.1:7000 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005 |
