redis 3.0 入门

sxyzy

一.安装必要包
yum -y install gcc
二.linux下安装
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
安装好了之后，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"
　　测试成功
　　三.redis cluster集群搭建
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

[OK] All nodes agree about slots configuration.
>>> Check for open slots...
>>> Check slots coverage...
[OK] All 16384 slots covered.
