一、简介
二、生产集群搭建
准备
- Linux服务器三台(三主三从)
下载
准备好Redis源码包，官网下载地址
解压
#如果可以连接网络可以使用命令下载 wget http://download.redis.io/releases/redis-6.7.0.tar.gz
tar -xvf redis-6.0.7.tar.gz -C /usr/local/redis/
[root@localhost redis]# ls
redis-6.0.7 redis-6.0.7.tar.gz
解压后目录如下
[root@localhost redis]# cd redis-6.0.7/
[root@localhost redis-6.0.7]# ll

编译
cd redis-6.0.7/
make
编译成功
Hint: It's a good idea to run 'make test' ;)
make[1]: Leaving directory `/usr/local/redis/redis-6.0.7/src'
成功会在src目录下创建可执行文件, 如下:
redis-benchmark
redis-check-aof
redis-check-rdb
redis-cli
redis-sentinel
redis-server
redis-trib.rb
安装
cd redis-6.0.7/
make install
安装成功
cd src && make install
make[1]: Entering directory `/usr/local/redis/redis-6.0.7/src'
Hint: It's a good idea to run 'make test' ;)
INSTALL install

make[1]: Leaving directory `/usr/local/redis/redis-6.0.7/src'
创建集群配置目录
# 规划好自己的安装目录
mkdir -p /usr/local/redis/cluster
cd /usr/local/redis/cluster
mkdir 7000 7001 7002 7003 7004 7005
修改配置文件
cp ../redis-6.0.7/redis.conf ./7000/
cd 7000/
mv redis.conf 7000.conf
vim 7000.conf
port 7000：指定当前Redis服务的端口，默认为6379
daemonize yes：配置redis作为守护进程运行
cluster-enabled yes：开启集群功能
bind 10.252.21.154 127.0.0.1：绑定本地回环地址
appendonly yes：配置数据持久化 aof模式
pidfile /usr/local/redis/cluster/7000/redis_7000.pid: 修改pid位置
logfile "redis_7000.log" : 日志文件名
dir /usr/local/redis/cluster/7000/：数据存储位置
按照以上修改所有配置文件，注意不同IP和端口，配置文件放在不同目录下。
启动Redis
cd /usr/local/redis/cluster/
redis-server 7000/7000.conf
redis-server 7001/7001.conf
redis-server 7002/7002.conf
redis-server 7003/7003.conf
redis-server 7004/7004.conf
redis-server 7005/7005.conf
