Linux(CentOS7) 环境搭建 redis5.0.8 集群

标签：实例   slots   start   art   centos7   ini   解压   assign   slot   

本篇文章，阐述从Centos7 min版 ，从0搭建redis集群

如果Centos7 最小化安装没有ifconfig这个命令：

yum install net-tools

安装完成之后

安装rz sz 工具 ：yum -y install lrzsz

将下载好的 redis 安装包和 ruby 安装包上传到linux 解压

tar zxvf  redis-stable.tar.gz          

tar zxvf  ruby-2.6.6.tar.gz

yum install gcc-c++

make MALLOC=libc

yum install -y tcl

make test

make install PREFIX=/usr/local/redis

 cd redis-stable

 cp redis.conf /usr/local/redis/bin/

vi redis.conf 

daemonize yes

前端启动：./redis-server

后端启动： ./redis-server redis.conf  

客户端操作： ./redis-cli 

#############################单机版Redis搭建完成##################################

[root@localhost local]# mkdir redis-cluster

修改配置文件
[root@localhost redis]# cp -r bin/ /usr/local/redis-cluster/
[root@localhost redis]# cd /usr/local/redis-cluster/
[root@localhost redis-cluster]# mv bin/ redis01
[root@localhost redis-cluster]# vi redis01/redis.conf

bind 127.0.0.1 192.168.198.132
port 6001
cluster-enabled yes

复制6份

[root@localhost redis-cluster]# cp -r redis01/ redis02
[root@localhost redis-cluster]# cp -r redis01/ redis03
[root@localhost redis-cluster]# cp -r redis01/ redis04
[root@localhost redis-cluster]# cp -r redis01/ redis05
[root@localhost redis-cluster]# cp -r redis01/ redis06

修改对应端口 6002 6003 6004 6005 6006

[root@localhost redis-cluster]# touch start.sh

cd redis01
./redis-server redis.conf
cd ..
cd redis02
./redis-server redis.conf
cd ..
cd redis03
./redis-server redis.conf
cd ..
cd redis04
./redis-server redis.conf
cd ..
cd redis05
./redis-server redis.conf
cd ..
cd redis06
./redis-server redis.conf
cd ..

脚本授权：
[root@localhost redis-cluster]# chmod +x start.sh

启动redis实例
[root@localhost redis-cluster]# ./start.sh
