Redis|Redis 集群搭建

Redis 集群搭建 (伪集群) 软件环境 centos7.3 (虚拟机)
redis 5.0.5
搭建步骤 创建相关目录

  • 创建主文件夹redis-cluster 在此文件夹下面创建六个子文件夹
mkdir /opt/redis-cluster cd /opt/redis-cluster mkdir 7000 7001 7002 7003 7004 7005

安装redis 5.0.5
  • redis官网下载压缩包拷贝到/opt/redis-cluster中
  • 编译安装
cd /opt/redis-cluster/redis5.0.5 make MALLOC=libc cd src && make install

启动六个redis实例
  • 移动redis.conf文件到每个实例中
cp /opt/redis-cluster/redis5.0.5/redis.conf /opt/redis-cluster/7000

  • 修改配置
# bind 192.168.1.187//绑定服务器IP地址(注释掉开启远程连接) port 7000//绑定端口号,必须修改,以此来区分Redis实例daemonize yes//后台运行pidfile /var/run/redis-7000.pid//修改pid进程文件名,以端口号命名logfile /root/application/program/redis-cluster/7000/redis.log//修改日志文件名称,以端口号为目录来区分dir /root/application/program/redis-cluster/7000///修改数据文件存放地址,以端口号为目录名来区分cluster-enabled yes//启用集群cluster-config-file nodes-7000.conf//配置每个节点的配置文件,同样以端口号为名称cluster-node-timeout 15000//配置集群节点的超时时间,可改可不改appendonly yes//启动AOF增量持久化策略appendfsync always//发生改变就记录日志protected-mode no

  • 启动六个redis实例
cd /opt/redis-cluster/redis5.0.5/src cp /redis-server ../ cp /redis-cli ../ cd ../ redis-server /opt/redis-cluster/7000/redis.conf redis-server /opt/redis-cluster/7001/redis.conf redis-server /opt/redis-cluster/7002/redis.conf redis-server /opt/redis-cluster/7003/redis.conf redis-server /opt/redis-cluster/7004/redis.conf redis-server /opt/redis-cluster/7005/redis.conf

创建集群
  • 执行创建集群命令
cd /opt/redis-cluster/redis5.0.5 redis-cli --cluster create 192.168.1.187:7000 192.168.1.187:7001 192.168.1.187:7002 192.168.1.187:7003 192.168.1.187:7004 192.168.1.187:7005 --cluster-replicas 1

全部重启
  • 删除所有实例下面的 appendonly.aof 和 nodes-700*.conf
cd /opt/redis-cluster/ find . -name '*.aof' -type f -print -exec rm -rf {} \; find . -name 'nodes-700*' -type f -print -exec rm -rf {} \;

  • 杀掉所有redis实例进程
pkill -9 redis

  • 重新启动所有redis实例
redis-server /opt/redis-cluster/7000/redis.conf redis-server /opt/redis-cluster/7001/redis.conf redis-server /opt/redis-cluster/7002/redis.conf redis-server /opt/redis-cluster/7003/redis.conf redis-server /opt/redis-cluster/7004/redis.conf redis-server /opt/redis-cluster/7005/redis.conf

  • 创建集群
redis-cli --cluster create 192.168.1.187:7000 192.168.1.187:7001 192.168.1.187:7002 192.168.1.187:7003 192.168.1.187:7004 192.168.1.187:7005 --cluster-replicas 1
