(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)
192.168.1.160:7000
192.168.1.160:7001
192.168.1.160:7001
192.168.1.160:7002
192.168.1.160:7003
192.168.1.160:7004
192.168.1.160:7005
1:下载redis。官网下载3.0.0版本,之前2.几的版本不支持集群模式
2:上传服务器,解压,编译
tar -zxvf redis-3.0.0.tar.gz
mv redis-3.0.0.tar.gz redis3.0
cd /usr/local/redis3.0
make
make install
|
3:创建集群需要的目录
mkdir -p /usr/local/cluster
cd /usr/local/cluster
mkdir 7000
mkdir 7001
mkdir 7002
mkdir 7003
mkdir 7004
mkdir 7005
|
4:修改配置文件redis.conf
cp /usr/local/redis3.0/redis.conf /usr.local/cluster
vi redis.conf
##修改配置文件中的下面选项
port 7000
daemonize yes
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
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7000/7001/7002/7003/7004/7005目录下面
cp /usr/local/cluster/redis.conf /usr/local/cluster/7000
cp /usr/local/cluster/redis.conf /usr/local/cluster/7001
cp /usr/local/cluster/redis.conf /usr/local/cluster/7002
cp /usr/local/cluster/redis.conf /usr/local/cluster/7003
cp /usr/local/cluster/redis.conf /usr/local/cluster/7004
cp /usr/local/cluster/redis.conf /usr/local/cluster/7005
##注意:拷贝完成之后要修改7001/7002/7003/7004/7005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
cd /usr/local/cluster/7000
redis-server redis.conf
cd /usr/local/cluster/7001
redis-server redis.conf
cd /usr/local/cluster/7002
redis-server redis.conf
cd /usr/local/cluster/7003
redis-server redis.conf
cd /usr/local/cluster/7004
redis-server redis.conf
cd /usr/local/cluster/7005
redis-server redis.conf
##启动之后使用命令查看redis的启动情况ps -ef|grep redis
如下图显示则说明启动成功

6:执行redis的创建集群命令创建集群
cd /usr/local/redis3.0/src
./redis-trib.rb create --replicas 1 192.168.1.160:7000 192.168.1.160:7001 192.168.1.160:7002 192.168.1.160:7003 192.168.1.160:7004 192.168.1.160:7005
|
6.1执行上面的命令的时候可能会报错,因为是执行的ruby的脚本,需要ruby的环境
错误内容:/usr/bin/env:ruby: No such file or directory
所以需要安装ruby的环境,这里推荐使用yum install ruby安装
yum install ruby
|
6.2然后再执行第6步的创建集群命令,可能还会报错,提示缺少rubygems组件,使用yum安装
错误内容:
./redis-trib.rb:24:in `require': no suchfile to load -- rubygems (LoadError)
from./redis-trib.rb:24
yum install rubygems
|
6.3再次执行第6步的命令,可能还会报错,提示不能加载redis,是因为缺少redis和ruby的接口,使用gem 安装
错误内容:
/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in`gem_original_require': no such file to load -- redis (LoadError)
from/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'
from./redis-trib.rb:25
gem install redis

6.4 再次执行第6步的命令,正常执行
<ignore_js_op>![](http://bbs.superwu.cn/data/attachment/forum/201506/09/144106pehxx3d3z50sdsbr.png)
![](http://bbs.superwu.cn/data/attachment/forum/201506/09/144106pehxx3d3z50sdsbr.png)
输入yes,然后配置完成。

至此redis集群即搭建成功!
7:使用redis-cli命令进入集群环境
redis-cli -c -p 7000
