1. redis5.0.14 集群搭建

1.1 服务部署

1.1.1 安装包下载

https://download.redis.io/releases/redis-5.0.14.tar.gz

1.1.2 服务安装

tar -xzvf redis-5.0.14.tar.gz 
cd redis-5.0.14/
make
cd src/
make install PREFIX=/usr/local/redis
mkdir /usr/local/redis/etc
cp /data01/software/redis-5.0.14/redis.conf /usr/local/redis/etc/

1.1.3 配置文件修改

创建所需目录

mkdir -p /data01/redis/data/6380
mkdir -p /data01/redis/data/6381
mkdir -p /data01/redis/data/6382
mkdir -p /data01/redis/data/6383
mkdir -p /data01/redis/data/6384
mkdir -p /data01/redis/data/6385
mkdir -p /data01/redis/log

集群最少 6 台机器

修改 demo 配置文件

cp /usr/local/redis/etc/redis.conf cp /usr/local/redis/etc/redis_demo.conf
VIM /usr/local/redis/etc/redis_demo.conf

# 修改如下配置
bind 10.0.8.7
daemonize yes
port 6380
pidfile /var/run/redis_6380.pid
logfile "/data01/redis/log/6380.log"
dir /data01/redis/data/6380
cluster-config-file nodes_6380.conf # 不需要创建会自动生成
cluster-node-timeout 15000
cluster-enabled yes

拷贝配置文件

# 按照所需要的port依次修改6个配置文件
mkdir /usr/local/redis/etc/cluster
cp /usr/local/redis/etc/redis_demo.conf /usr/local/redis/etc/cluster/redis_6380.conf
cp /usr/local/redis/etc/redis_demo.conf /usr/local/redis/etc/cluster/redis_6381.conf
cp /usr/local/redis/etc/redis_demo.conf /usr/local/redis/etc/cluster/redis_6382.conf
cp /usr/local/redis/etc/redis_demo.conf /usr/local/redis/etc/cluster/redis_6383.conf
cp /usr/local/redis/etc/redis_demo.conf /usr/local/redis/etc/cluster/redis_6384.conf
cp /usr/local/redis/etc/redis_demo.conf /usr/local/redis/etc/cluster/redis_6385.conf

1.1.4 启动服务

# 启动脚本 start_all.sh
/usr/local/redis/bin/redis-server /usr/local/redis/etc/cluster/redis_6380.conf
/usr/local/redis/bin/redis-server /usr/local/redis/etc/cluster/redis_6381.conf
/usr/local/redis/bin/redis-server /usr/local/redis/etc/cluster/redis_6382.conf
/usr/local/redis/bin/redis-server /usr/local/redis/etc/cluster/redis_6383.conf
/usr/local/redis/bin/redis-server /usr/local/redis/etc/cluster/redis_6384.conf
/usr/local/redis/bin/redis-server /usr/local/redis/etc/cluster/redis_6385.conf
# 停止脚本 shutdown_all.sh
/usr/local/redis/bin/redis-cli -h 10.0.8.7 -p 6380 shutdown
/usr/local/redis/bin/redis-cli -h 10.0.8.7 -p 6381 shutdown
/usr/local/redis/bin/redis-cli -h 10.0.8.7 -p 6382 shutdown
/usr/local/redis/bin/redis-cli -h 10.0.8.7 -p 6383 shutdown
/usr/local/redis/bin/redis-cli -h 10.0.8.7 -p 6384 shutdown
/usr/local/redis/bin/redis-cli -h 10.0.8.7 -p 6385 shutdown

1.1.5 检查服务

ps -ef|grep Redis

1.2 创建集群

/usr/local/redis/bin/redis-cli --cluster create --cluster-replicas 1 10.0.8.7:6380 10.0.8.7:6381 10.0.8.7:6382 10.0.8.7:6383 10.0.8.7:6384 10.0.8.7:6385

1.3 验证集群

/usr/local/redis/bin/redis-cli -c -h 10.0.8.7 -p 6380
