docker容器部署redis集群cluster

本文是在一台服务器上搭建的redis集群

1.安装docker

闭防火墙

# setenforce 0

# systemctl stop firewalld

# systemctl disable firewalld

# sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config

# yum -y install docker-ce

启动docker

# systemctl start docker

# systemctl enable docker

# curl -L https://get.daocloud.io/docker/compose/releases/download/1.25.0/docker-compose-u `name -s-uname -m `> /usr/local/bin/docker-compose

# chmod +x /usr/local/bin/docker-compose

2.在同一目录下，添加以下文件

# vim cluster.sh

#!/bin/bash

BASEPATH='/usr/local/redis'         #redis节点数据和配置文件存放路径

IP=192.168.184.128          #修改为环境对应地址

docker pull redis:5.0.3        #redis镜像版本

for i in `seq 7001 7006`        #redis节点端口范围

do

 mkdir -p $BASEPATH/${i}/data/

 mkdir -p $BASEPATH/${i}/config/

 cp ./redis.conf $BASEPATH/${i}/config/

 sed -i "s/port 6379/port ${i}/" $BASEPATH/${i}/config/redis.conf

 echo "cluster-announce-ip $IP" >> $BASEPATH/${i}/config/redis.conf

 echo "cluster-announce-port ${i}" >> $BASEPATH/${i}/config/redis.conf

 echo "cluster-announce-bus-port 1${i}" >> $BASEPATH/${i}/config/redis.conf

done

cp docker-compose.yml redis-cli $BASEPATH/

cd $BASEPATH

docker-compose up -d

chmod u+x redis-cli

./redis-cli -h $IP -p 7001 --cluster create $IP:7001 $IP:7002 $IP:7003 $IP:7004 $IP:7005 $IP:7006 --cluster-replicas 1        #创建redis集群

# vim docker-compose.yml

并在此目录下放入redis-cli文件

3.构建并启动redis集群容器

[root@localhost redis]# sh cluster.sh

4.进到 BASEPATH定义的目录下，可以批量停启容器

[root@localhost redis]# cd /edoc/redis

[root@localhost redis]# docker-compose ps

 Name               Command               State                             Ports
