redis集群搭建(docker)

记录一下:

1 运行了一个ubantu镜像 

docker run -itd -p 10001:10001 -p 10002:10002 -p 10003:10003 -p 10004:10004 -p 10005:10005 -p 10006:10006 镜像名 /bin/bash

2 下载redis 

wget http://download.redis.io/releases/redis-6.0.6.tar.gz

3 ubantu 镜像真干净 (没有make  gcc)

yum install gcc gcc-c++ make automake autocon

4 解压

tar xzf redis-6.0.6.tar.gz
cd redis-6.0.6
make
make install 

5 运行测试 

redis-server
redis-cli

 6 开始搭建

mkdir -p /usr/local/redis-cluster/
cd /usr/local/redis-cluster/
mkdir 10001 10002 10003 10004 10005 10006
# cd 到 redis-6.0.6
cp redis.conf /usr/local/redis-cluster/10001
vim /usr/local/redis-cluster/10001/redis.conf

 7 配置redis.conf (vim 中  /字符串) 查找

bind  172.17.0.2  # 自己的容器ip 
port 10001  #  端口尽量与文件夹一致
daemonize yes  #  设置守护
dir /usr/local/redis-cluster/10001/ # 指定配置文件路径
appendonly yes   #  开启日志
cluster-enabled yes  # 开启集群
cluster-config-file nodes-10002.conf # 指定节点文件
cluster-node-timeout 5000

 8 运行测试

redis-server /usr/local/redis-cluster/10001/redis.conf

9 配置多个节点( vim 命令     /%s/旧字符串/新字符串/g) 全局替换

cp  /usr/local/redis-custer/10001/redis.conf  /usr/local/redis-custer/10002/
vim /usr/local/redis-custer/10002/redis.conf 
/%s/10001/10002/g
.....
....
...
..
.

10.运行测试

redis-server /usr/local/redis-cluster/10001/redis.conf
redis-server /usr/local/redis-cluster/10002/redis.conf
redis-server /usr/local/redis-cluster/10003/redis.conf
redis-server /usr/local/redis-cluster/10004/redis.conf
redis-server /usr/local/redis-cluster/10005/redis.conf
redis-server /usr/local/redis-cluster/10006/redis.conf

ps -ef |grep redis

11.创建集群     (redis5.0 之后 不在采用ruby 启动  而是c)

redis-cli --cluster create 172.17.0.2:10001 172.17.0.2:10002 172.17.0.2:10003 172.17.0.2:10004 172.17.0.2:10005 172.17.0.2:10006 --cluster-replicas 1



成功 ....

12 验证

redis-cli -c -p 172.17.0.2 -p 10001  
cluster-info  # 查看集群信息
cluster nodes #  查看节点详细信息 

13 杀掉集群

# kill 掉 ps -ef | grep redis 进程
rm /usr/local/redis-custer/10001/redis-nodes-10002.conf appendonly.aof  # 删除这两个文件
# 再重复  10, 11
