Ubuntu下redis安装及其操作

安装redis数据库

$sudo apt-get update$sudo apt-get install redis-server1.启动redis服务$sudo /etc/init.d/redis-server restart$sudo service redis-server restart2.连接redis 　　$ redis-cli -h 127.0.0.1 -p 6379

redis个版本的下载地址如下（接下来的部署都是以下面的版本而不是上面方便的ubuntu下默认的redis版本）

http://download.redis.io/releases/redis-3.2.4.tar.gz

4.进入解压目录编译

make

5.安装redis

make install PREFIX=/usr/local/redis

参照官方说明，支持redis主备，最少部署六个节点，三主三备

mkdir redis-clustercd redis-clustermkdir 7000 7001 7002 7003 7004 7005

将编译好的/usr/local/redis/目录下的bin 拷贝到7000 7001等 这些目录下

分别进入到7000,7001,7002,7003，7004,7005的bin目录中，修改redis.conf 文件，添加以下内容

port 7000cluster-enabled yescluster-config-file nodes.confcluster-node-timeout 5000appendonly yes依次port 7001。。。

分别启动以上六个redis实例
进入到7000/bin目录下，执行
然后7001…

./redis-server ./redis.conf7001/bin/redis-server ./redis.conf....

创建集群这个redis-trib.rb工具是用 ruby 实现的，所以需要安装 ruby。安装命令如下：
yum -y install ruby ruby-devel rubygems rpm-build
gem install redis

创建集群
./redis-trib.rb create –replicas 1 192.168.25.153:7001 192.168.25.153:7002 192.168.25.153:7003 192.168.25.153:7004 192.168.25.153:7005 192.168.25.153:7006

6、测试集群（-c 不能缺）

进入集群任一文件夹下输入redis01/redis-cli -h 192.168.25.153 -p 7002 -c
