docker搭建redis集群高可用分片

本文主要是介绍docker搭建redis集群高可用分片，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

docker搭建redis集群高可用分片

创建redis集群的网卡
编写shell脚本，创建redis集群卷本机目录
docker run启动6个容器(后面有脚本，可以在创建目录时同时启动容器)
容器秒退错误信息查看
进入其中一个容器配置redis分片集群
redis-cli -c在容器内查看集群主从关系
高可用测试
- 插入值
- 删除操作节点
- 查看集群节点状态，并获取值
- 查看本机挂载目录
shell脚本执行创建数据卷目录及运行6容器

创建redis集群的网卡

docker network create redis --subnet 192.169.0.0/16

运行输出查看网卡

[root@VM-0-3-centos pdx_haokai]# docker network create redis --subnet 192.169.0.0/16
d9437fa2e1bbc7101badf40ba17a9c8f551e0bc40bfc85ea79875fe641015f78
[root@VM-0-3-centos pdx_haokai]# docker network ls

d9437fa2e1bb   redis     bridge    local
[root@VM-0-3-centos pdx_haokai]#

编写shell脚本，创建redis集群卷本机目录

# 通过脚本创建6个redis配置
for port in $(seq 1 6); \
do \
mkdir -p /home/pdx_haokai/mydata/redis/node-${port}/conf
touch /home/pdx_haokai/mydata/redis/node-${port}/conf/redis.conf
cat << EQF >/home/pdx_haokai/mydata/redis/node-${port}/conf/redis.conf
port 6379
bind 0.0.0.0
cluster-enabled yes
cluster-config-file nodes-conf
cluster-announce-ip 192.169.0.1${port}
cluster-announce-port 6379
cluster-announce-bus-port 16379
appendonly yes
EQF
done

创建完后，目录结构是这样的

[root@VM-0-3-centos pdx_haokai]# for port in $(seq 1 6); \
> do \
> mkdir -p /home/pdx_haokai/mydata/redis/node-${port}/conf
> touch /home/pdx_haokai/mydata/redis/node-${port}/conf/redis.conf

docker run启动6个容器(后面有脚本，可以在创建目录时同时启动容器)

参数解析：
-p开启两个端口映射，一个外网交互，一个集群间通信

容器秒退错误信息查看

如果启动容器秒退，代表出错了，可以使用docker start -i 容器id可以看到报错内容，然后解决

[root@VM-0-3-centos pdx_haokai]# docker start -i e4b93f0e6623

*** FATAL CONFIG FILE ERROR ***

>>> 'cluster-enbaled yes'

[root@VM-0-3-centos pdx_haokai]#

进入其中一个容器配置redis分片集群

redis-cli：代表redis单机模式
redis-cli -c：代表redis集群模式
cluster-replicas：表示分片，replicas 1 表示我们希望为集群中的每个主节点创建一个从节点，不设置分片的话，所有节点都是master。

这里进入使用的是 docker exec -it 容器id /bin/sh，因为redis容器里没有/bin/bash。

/data # redis-cli --cluster create 192.169.0.11:6379 192.169.0.12:6379 192.169.0.13:6379 192.169.0.14:6379 192.169.0.15:6379 192.169.0.16:6379 --cluster-replicas 1

高可用测试

redis主从高可用，保证主节点挂掉，从节点会自动通过选举成为主节点，同时各节点数据主从复制。

插入值

shell脚本执行创建数据卷目录及运行6容器

参数解析：
-p开启两个端口映射，一个外网交互，一个集群间通信

# 通过脚本创建6个redis配置并运行容器

Redis教程

docker搭建redis集群高可用分片

docker搭建redis集群高可用分片

创建redis集群的网卡

编写shell脚本，创建redis集群卷本机目录

docker run启动6个容器(后面有脚本，可以在创建目录时同时启动容器)

容器秒退错误信息查看

进入其中一个容器配置redis分片集群

redis-cli -c在容器内查看集群主从关系

高可用测试

插入值

删除操作节点

查看集群节点状态，并获取值

查看本机挂载目录

shell脚本执行创建数据卷目录及运行6容器
