一、安装redis
1.安装gcc
命令：sudoapt-getbuild-depgcc或者 sudoapt-getinstallbuild-essential
安装完查看gcc 版本：gcc--version
2..把源码包上传到ubuntu服务器
3.解压源码包：tar -zxvf redis-3.0.0.tar.gz
4.在redis 目录 进行make: 命令：make
5.Make install：
[root@bogon redis-3.0.0]# make install PREFIX=/usr/local/redis
6.启动：
①、前端启动模式
/usr/local/redis/bin/redis-server
默认是前端启动模式，端口是6379
②：后端启动
A、从redis的源码目录中复制redis.conf到redis的安装目录
B、修改配置文件：vim redis.conf（usr/local/redis 目录下的配置文件）
7使用
1）./redis-server redis.conf
8.常用命令
127.0.0.1:6379> set a 10
OK
127.0.0.1:6379> get a
"10"
查看所有key：keys *
删除指定的key: del a
关闭redis：shutdown（单机版）；-p 7001 shutdown(指定端口)
redis01/redis-server redis.conf
../redis02/redis-server redis.conf
expire key1 100 :设定key1 的有效时间为100秒
ttl key1 ： 查看key的有效时间，-1 为永久，-2表示数据已被删除
Incr a ： 返回a 自增的值
二、ruby环境的搭建（群集需要ruby环境）
1.安装ruby
# sudo apt-get update
# sudo apt-get install ruby
2.安装rubygems
gem install mygem
3.redis集群管理工具redis-trib.rb
[root@bogon ~]# cd redis-3.0.0
[root@bogon redis-3.0.0]# cd src
[root@bogon src]# ll *.rb
显示：
-rwxrwxr-x. 1 root root 48141 Apr 1 07:01 redis-trib.rb
[root@bogon src]#
4.脚本需要的ruby包：
需要上传到linux服务。
安装ruby的包：
gem installredis-3.0.0.gem
[root@bogon ~]# gem install redis-3.0.0.gem
显示：
Successfully installed redis-3.0.0
1 gem installed
Installing ri documentation for redis-3.0.0...
Installing RDoc documentation for redis-3.0.0...
三、redis 群集的搭建（只建立3个redis节点，3个主3个备份）
1. 创建redis-cluster：mkdir redis-cluster
2. 将redis 中的 bin复制到 redis-cluster，命名为redis01（其他5个实例类似）
cd redis
cp -r bin ../redis-cluster/redis01
3.修改 redis01 的端口号，6个实例redis端口号分别为7001-7006
Vim redis.conf
打开cluster-enable前面的注释。
4. 将redis-3.0.0下src 下的redis-trib.rb复制到 /usr/local/redis-cluster/ 下
cp *.rb /usr/local/redis-cluster/
5. 启动6个redis实例
6. 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 |
结果：
