CentOS7安装配置redis-3.0.0
一.安装必要包
yum install gcc
二.linux下安装
#下载 wget http://download.redis.io/releases/redis-3.0.0.tar.gz tar zxvf redis-3.0.0.tar.gz cd redis-3.0.0 #如果不加参数,linux下会报错 make MALLOC=libc
安装好之后,启动文件
#启动redis src/redis-server & #关闭redis src/redis-cli shutdown
测试redis
$ src/redis-cli 127.0.0.1:6379> set foo bar OK 127.0.0.1:6379> get foo "bar" $
测试成
3.redis cluster集群搭建
建立本机测试环境
建立运行目录
#建立redis运行目录 mkdir -p redis-server/7000/ #复制默认的配置文档 cp redis-3.0.0/redis.conf redis-server/redis.default.conf #把编译好的server复制到运行目录 cp redis-3.0.0/src/redis-server redis-server/7000/
建立独立配置文件
#在7000目录下建立redis的配置文档 vim redis-server/7000/redis.conf
文件内容
#redis-server/7000/redis.conf include /root/redis-server/redis.default.conf pidfile /var/run/redis-7000.pid port 7000 cluster-enabled yes cluster-config-file redis-node-7000.conf cluster-node-timeout 5000 appendonly yes
复制运行目录(模拟集群环境)
#复制目录 cp -R 7000/ 7001/ cp -R 7000/ 7002/ cp -R 7000/ 7003/ cp -R 7000/ 7004/ cp -R 7000/ 7005/
修改相应配置文件的端口和文件名
建立启动脚本 redis-server/redis-start.sh
#!/bin/sh /root/redis-server/7000/redis-server /root/redis-server/7000/redis.conf & /root/redis-server/7001/redis-server /root/redis-server/7001/redis.conf & /root/redis-server/7002/redis-server /root/redis-server/7002/redis.conf & /root/redis-server/7003/redis-server /root/redis-server/7003/redis.conf & /root/redis-server/7004/redis-server /root/redis-server/7004/redis.conf & /root/redis-server/7005/redis-server /root/redis-server/7005/redis.conf &
配置集群
安装ruby
yum install ruby-devel.x86_64
安装redis gem
# gem install redis Fetching: redis-3.2.1.gem (100%) Successfully installed redis-3.2.1 Parsing documentation for redis-3.2.1 Installing ri documentation for redis-3.2.1 1 gem installed
使用脚本建立集群机制
在create的时候,加上参数--replicas 1 表示为每个master分配一个salve,如例子,则是3个master 3个salve
# ./redis-trib.rb create 127.0.0.1:7000 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005 >>> Creating cluster Connecting to node 127.0.0.1:7000: OK Connecting to node 127.0.0.1:7001: OK Connecting to node 127.0.0.1:7002: OK Connecting to node 127.0.0.1:7003: OK Connecting to node 127.0.0.1:7004: OK Connecting to node 127.0.0.1:7005: OK >>> Performing hash slots allocation on 6 nodes...

如果需要全部重新自动配置,则删除所有的配置好的cluster-config-file,重新启动所有的redis-server,然后重新执行配置命令即可
