redis集群搭建详细步骤

1、下载redis5.0

wget http://download.redis.io/releases/redis-5.0.2.tar.gz

2、安装redis编译需要的环境

yum -y install gcc gcc-c++

3、编译安装redis

tar zxf redis-5.0.2.tar.gz cd redis-5.0.2/ make MALLOC=libc && make install

4、编写集群7001-7006

mkdir -p /usr/local/redis/{7001..7006} cp redis.conf /usr/local/redis/7001/ cp redis.conf /usr/local/redis/7002/ cp redis.conf /usr/local/redis/7003/ cp redis.conf /usr/local/redis/7004/ cp redis.conf /usr/local/redis/7005/ cp redis.conf /usr/local/redis/7006/ cd /usr/local/redis/

5、因为在一台上所以不用改ip,修改集群7001-7006主要配置以下，port、和cluster-config-file不能一样

vim 7001/redis.conf

6、集群7001-7006主要配置修改后启动7001-7006,当出现这个中文错误，去掉中文在启动

for i in `seq 1 6`; do redis-server /usr/local/redis/700$i/redis.conf; done

查询端口

netstat -anpt|grep redis

8、启动集群当出现 /usr/bin/env: ruby: 没有那个文件或目录,需要准备redis-trib.rb的运行环境,并安装redis-trib依赖

cd /root/redis-5.0.2/src/ ./redis-trib.rb -create --replica 1 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005 127.0.0.1:7006 wget https://cache.ruby-lang.org/pub/ruby/2.5/ruby-2.5.1.tar.gz yum -y install zlib-devel tar xvf ruby-2.5.1.tar.gz cd ruby-2.5.1/ ./configure -prefix=/usr/local/ruby make make install cd /usr/local/ruby/ cp bin/ruby /usr/local/bin cp bin/gem /usr/local/bin wget http://rubygems.org/downloads/redis-3.3.0.gem gem install -l redis-3.3.0.gem cd /root/redis-5.0.2/src/ redis-cli --cluster create 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 127.0.0.1:7006 --cluster-replicas 1

9、测试
