Redis集群Centos6.6

Redis目录

/usr/local/redis-3.2.0

环境复制：

mkdir -p /usr/local/cluster
mkdir -p /usr/local/cluster/7000
mkdir -p /usr/local/cluster/7001
mkdir -p /usr/local/cluster/7002
mkdir -p /usr/local/cluster/7003
mkdir -p /usr/local/cluster/7004
mkdir -p /usr/local/cluster/7005
cp -rf /usr/local/redis-3.2.0/* /usr/local/cluster/7000
cp -rf /usr/local/redis-3.2.0/* /usr/local/cluster/7001
cp -rf /usr/local/redis-3.2.0/* /usr/local/cluster/7002
cp -rf /usr/local/redis-3.2.0/* /usr/local/cluster/7003
cp -rf /usr/local/redis-3.2.0/* /usr/local/cluster/7004
cp -rf /usr/local/redis-3.2.0/* /usr/local/cluster/7005

修改配置文件redis.conf

vi /usr/local/cluster/7000/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

同样再对其它配置文件进行修改
vi /usr/local/cluster/7001/redis.conf
vi /usr/local/cluster/7002/redis.conf
vi /usr/local/cluster/7003/redis.conf
vi /usr/local/cluster/7004/redis.conf
vi /usr/local/cluster/7005/redis.conf

 

启动6个redis

cd /usr/local/cluster/7000/src
redis-server ../redis.conf
cd /usr/local/cluster/7001/src
redis-server ../redis.conf
cd /usr/local/cluster/7002/src
redis-server ../redis.conf
cd /usr/local/cluster/7003/src
redis-server ../redis.conf
cd /usr/local/cluster/7004/src
redis-server ../redis.conf
cd /usr/local/cluster/7005/src
redis-server ../redis.conf

 

 cd /usr/local/redis-3.2.0/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

 

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

yum install ruby

 

然后再执行第步的创建集群命令，还会报错，提示缺少rubygems组件
错误内容：
./redis-trib.rb:24:in `require': no such file to load -- rubygems (LoadError)
from ./redis-trib.rb:24
yum install rubygems

 

再次执行第步的命令，还会报错，提示不能加载redis，是因为缺少redis的接口
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
这里可能无法安装,因为无法连接gem服务器：
[@zw_22_90 src]# gem install redis --version 3.0.0
ERROR: Could not find a valid gem 'redis' (= 3.0.0) in any repository
ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)


需要手工下载并安装：
wget https://rubygems.global.ssl.fastly.net/gems/redis-3.2.1.gem
gem install -l ./redis-3.2.1.gem

 

 

再次执行第步的命令，正常执行
输入yes，然后配置完成。
[@zw_22_90 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

 

redis-cli命令进入集群环境
[@zw_22_90 src]# redis-cli -c -p 7000

127.0.0.1:7000> set foo bar
