Redis3.0.1 Stable版本的集群部署（Mac）

本文档基于如下原始文档（CentOS）创建：

http://blog.csdn.net/xu470438000/article/details/42971091

修改了一些路径的错误，补全了一些命令执行结果信息，确认在Mac下创建集群成功

 

同时参考

http://blog.csdn.net/myrainblues/article/details/25881535

 

 

 

（要让集群正常工作至少需要3个主节点，在这里我们要创建6个redis节点，其中三个为主节点，三个为从节点，对应的redis节点的ip和端口对应关系如下）

• 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

 

1：官网下载3.0.1 Stable （http://redis.io/）

下载地址： http://download.redis.io/releases/redis-3.0.1.tar.gz

 

2：上传服务器，解压，编译

#将下载的文件放到 /usr/local/

tar -zxvf redis-3.0..tar.gz
#生成 redis-3.0.1文件夹

cd /usr/local/redis-3.0.
make
make install

#执行一下make test查看 make的结果全部都是OK
#最终结果显示如下
\o/ All tests passed without errors!

3：创建集群需要的目录 

mkdir -p /usr/local/cluster

cd /usr/local/cluster
mkdir 

mkdir 

mkdir 

mkdir 

mkdir 

mkdir 

4：修改配置文件redis.conf

cp /usr/local/redis-3.0./redis.conf  /usr/local/cluster
vi redis.conf

##修改配置文件中的下面选项

port 

daemonize yes

cluster-enabled yes

cluster-config-file nodes.conf

cluster-node-timeout 

appendonly yes

##修改完redis.conf配置文件中的这些配置项之后把这个配置文件分别拷贝到7000/////7005目录下面

cp /usr/local/cluster/redis.conf /usr/local/cluster/

cp /usr/local/cluster/redis.conf /usr/local/cluster/

cp /usr/local/cluster/redis.conf /usr/local/cluster/

cp /usr/local/cluster/redis.conf /usr/local/cluster/

cp /usr/local/cluster/redis.conf /usr/local/cluster/

cp /usr/local/cluster/redis.conf /usr/local/cluster/

##注意：拷贝完成之后要修改7001////7005目录下面redis.conf文件中的port参数，分别改为对应的文件夹的名称

5：分别启动这6个redis实例(实践证明，必须要cd到700X文件夹下执行redis-server命令)

cd /usr/local/cluster/

redis-server redis.conf

cd /usr/local/cluster/

redis-server redis.conf

cd /usr/local/cluster/

redis-server redis.conf

cd /usr/local/cluster/

redis-server redis.conf

cd /usr/local/cluster/

redis-server redis.conf

cd /usr/local/cluster/

redis-server redis.conf

##启动之后使用命令查看redis的启动情况ps -ef|grep redis
如下显示则说明启动成功

X0544: wei.li$ ps -ef | grep redis
           :31上午 ??         :01.07 redis-server *: [cluster]
           :44上午 ??         :00.29 redis-server *: [cluster]
           :48上午 ??         :00.05 redis-server *: [cluster]
           :49上午 ??         :00.03 redis-server *: [cluster]
           :49上午 ??         :00.02 redis-server *: [cluster]
           :49上午 ??         :00.01 redis-server *: [cluster]
         :49上午 ttys000    :00.00 grep redis

6：执行redis的创建集群命令创建集群 

cd /usr/local/redis-3.0.1/src

./redis-trib.rb  create --replicas  127.0.0.1: 127.0.0.1: 127.0.0.1: 127.0.0.1: 127.0.0.1: 127.0.0.1:

 

请注意：

本机已经安装rvm和rubygems，只需要执行

X0544:cluster wei.li$ gem install redis -V

即可安装完毕redis-rb

正常执行结果如下

X0544:src wei.li$ ./redis-trib.rb create --replicas  127.0.0.1: 127.0.0.1: 127.0.0.1: 127.0.0.1: 127.0.0.1: 127.0.0.1:
