redis集群搭建

1. 下载源码

wget http://download.redis.io/releases/redis-3.0.7.tar.gz

解压缩编译

cd redis-3.0.7
cd src
make
sudo make PREFIX=/usr/local/redis-2.4.4 install

修改用户的.bashrc
PATH变量增加/usr/local/redis-2.4.4/bin"
simomme@sud1:/usr/local/redis-2.4.4/bin$ sudo cp ~/002.tool/redis-3.0.7/redis.conf ./
修改配置文件，将其中的"daemonize no"行改为"daemonize yes"，让其在后台运行。

redis-server /usr/local/redis-2.4.4/bin/redis.conf

sudo apt-get install ruby

./redis-trib.rb:24:in `require': no such file to load -- rubygems (LoadError)
    from ./redis-trib.rb:24

   
sudo apt-get install rubygems
gem install redis

simomme@sud1:~/002.tool/redis-3.0.7/src$ sudo gem install redis

可能需要翻墙

ps -ef|grep "redis"

配置文件注意两个
1个是db  一个是node.conf
nodes-6380.conf

3台机器  每台两个实例
