Docker部署Redis cluster3.2.5集群的例子

来源: 网络整理  作者: 佚名

本文章为各位介绍关于Docker部署Redis cluster3.2.5集群的例子,希望这一篇文章能够为各位带来帮助,具体如下。
和之前一样,使用alpine的版本,redis 是3.2.5稳定版本
[root@LinuxEA redis1]# cat Dockerfile
FROM alpine
MAINTAINER wwww.111cn.net for mark
RUN apk update \
        && apk --no-cache add curl \
        && curl -sO http://download.redis.io/releases/redis-3.2.5.tar.gz \
        && tar xf redis-3.2.5.tar.gz -C /usr/local/ \
        && rm -rf redis-3.2.5.tar.gz  rm -rf /var/cache/apk/* \
        && cd /usr/local/redis-3.2.5 \
        && apk add --no-cache 'su-exec>=0.2' \
        && apk add --no-cache --virtual .build-deps gcc linux-headers make musl-dev tar \
        && make PREFIX=/usr/local/redis install \
        && apk del .build-deps tar gcc make  \
        && cp utils/redis_init_script /etc/init.d/redis \
        && chmod +x /etc/init.d/redis \
        && sed -i 's@EXEC=/usr/local/bin/redis-server@EXEC=/usr/local/redis/bin/redis-server@' /etc/init.d/redis \
        && sed -i 's@CLIEXEC=/usr/local/bin/redis-cli@CLIEXEC=/usr/local/redis/bin/redis-cli@' /etc/init.d/redis \
        && cd /usr/local \
        && rm -rf /var/cache/apk/* /usr/local/redis-3.2.5
EXPOSE 6379/tcp 6380/tcp 16379/tcp 16380/tcp
ENTRYPOINT /usr/local/redis/bin/redis-server /etc/redis/redis.conf
现将docker build,而后在做成仓库为其他机器提供:
docker build -t redis3.2.5 .
docker tag reids3 10.10.242.23:5000/alpinedocker push 10.10.242.23:5000/alpine`
docker仓库使用方法,可参考博客中docker仓库搭建文章:http://www.111cn.net/1424.html
通常需要6台主机,3主3从,我们是会用3台主机,每台主机2个redis容器,集群完成后,每台主机的两个redis不会是同一个主从
配置文件示例:我们需要修改端口号,和ip地址,以及pid的名称等,这里的ip地址使用的docker的hosts模式,这样将会简单的多,拓扑如下:

[root@LinuxEA 6379]# egrep -v "^$|^#" redis.conf
bind 10.10.242.23
protected-mode yes
port 6379
tcp-backlog 511

aof-rewrite-incremental-fsync yes
修改完成后,分别将3台服务器的docker run起来
10.10.239.194
[root@LinuxEA ~]# docker run --name 6381 --network=host -v /root/redis/6381/redis.conf:/etc/redis/redis.conf -d -p 6381:6381 -p 16381:16381 10.10.242.23:5000/alpine
[root@LinuxEA ~]# docker run --name 6382 --network=host -v /root/redis/6382/redis.conf:/etc/redis/redis.conf -d -p 6382:6382 -p 16382:16382 10.10.242.23:5000/alpine
10.10.239.185
[root@LinuxEA ~]# docker run --name 6383 --network=host -v /root/redis/6383/redis.conf:/etc/redis/redis.conf -d -p 6383:6383 -p 16383:16383 10.10.242.23:5000/alpine
[root@LinuxEA ~]# docker run --name 6384 --network=host -v /root/redis/6384/redis.conf:/etc/redis/redis.conf -d -p 6384:6384 -p 16384:16384 10.10.242.23:5000/alpine
10.10.242.23
[root@LinuxEA ~]# docker run --name 6379 --network=host -v /root/redis/6379/redis.conf:/etc/redis/redis.conf -d -p 6379:6379 -p 16379:16379 10.10.242.23:5000/alpine
[root@LinuxEA ~]# docker run --name 6380 --network=host -v /root/redis/6380/redis.conf:/etc/redis/redis.conf -d -p 6380:6380 -p 16380:16380 10.10.242.23:5000/alpine
我们简单的添加一条规则放行:iptables -I INPUT -p tcp -j ACCEPT
现在我们可以来进行创建集群!
