Docker 部署 Redis集群

1. 创建redis镜像

mkdir /opt/docker_redis_cluster
cd /opt/docker_redis_cluster
wget http://download.redis.io/releases/redis-4.0.11.tar.gz
tar xvzf redis-4.0.11.tar.gz
cd redis-4.0.11
make

2.修改redis配置文件

vim /opt/docker_redis_cluster/redis-4.0.11/redis.conf
# 只修改其中的内容
bind 0.0.0.0                              #修改bindip 使其他用户可访问
daemonize no                            #关闭守护进程
requirepass 123456                        #添加密码
masterauth 123456                         #添加主从连接密码
logfile "/var/log/redis/redis-server.log"         #设置日志路径
cluster-enabled yes                          #配置集群相关信息
cluster-config-file nodes-6379.conf
cluster-node-timeout 15000

3. 制作镜像

vim /opt/docker_redis_cluster/Dockerfile
# Redis
# Version 4.0.11
FROM centos:7
ENV REDIS_HOME /usr/local
ADD redis-4.0.11.tar.gz /              # 本地的redis源码包复制到镜像的根路径下.
RUN mkdir -p $REDIS_HOME/redis     # 创建安装目录
ADD redis-4.0.11/redis.conf $REDIS_HOME/redis/  # 将一开始编译产生并修改后的配置复制到安装目录
RUN rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
RUN yum -y update                 # 更新yum源
RUN yum install -y gcc make         # 安装编译需要的工具
WORKDIR /redis-4.0.11
RUN make
RUN mv /redis-4.0.11/src/redis-server  $REDIS_HOME/redis/   # 只保留redis-server
WORKDIR /
RUN rm -rf /redis-4.0.11             # 删除解压文件
RUN yum remove -y gcc make        #删除多余的gcc跟make
VOLUME ["/var/log/redis"]             # 添加数据卷
EXPOSE 6379                       # 暴露6379端口

cd /opt/docker_redis_cluster/
docker build -t lyw/docker_redis_cluster .

4. 创建集群节点镜像

mkdir /opt/docker_redis_nodes
vim /opt/docker_redis_nodes/Dockerfile
# Redis Node
# Version 4.0.11
FROM lyw/docker_redis_cluster:latest
# MAINTAINER_INFO
MAINTAINER nestor nestor.yang@duxes.cn
ENTRYPOINT ["/usr/local/redis/redis-server", "/usr/local/redis/redis.conf"]

cd /opt/docker_redis_nodes/
docker build -t lyw/docker_redis_nodes .

# 查看
docker images

5. 启动redis容器

docker run -d --name redis-6380 -p 6380:6379 lyw/docker_redis_nodes 
docker run -d --name redis-6381 -p 6381:6379 lyw/docker_redis_nodes 
docker run -d --name redis-6382 -p 6382:6379 lyw/docker_redis_nodes 
docker run -d --name redis-6383 -p 6383:6379 lyw/docker_redis_nodes 
docker run -d --name redis-6384 -p 6384:6379 lyw/docker_redis_nodes 
docker run -d --name redis-6385 -p 6385:6379 lyw/docker_redis_nodes

6.连接redis

# 宿主机安装redis
yum install y redis

# 获取容器ip
docker ps

docker inspect 8f82b38d45ad  bc7a8ef02c14   0d7aed712a10 94076bca5ee1  87a8e8025f04 d6cb77761db6  |grep IPA
