redis集群配置 redis集群配置

版本信息：
ubuntu 16.04
gcc version 5.4.0
版本问题真的很重要，很有可能在别人的电脑里面可以正常操作，换一台就…呵呵，你懂得！
好，废话不多说，来代码！！
1.安装redis: 1）下载解压：

/usr/local$ sudo wget http://download.redis.io/releases/redis-3.0.2.tar.gz /usr/local$ sudo tar -xvzf redis-3.0.2.tar.gz /usr/local$ cd redis-3.0.2/

2)编译安装(/usr/local/redis-3.0.2/)

sudo make sudo make install

提示编译成功：

Hint: It's a good idea to run 'make test' ; ) make[1]: Leaving directory '/usr/local/redis-3.0.2/src'

2.配置文件修改： 1）创建文件夹：

/usr/local$ sudo mkdir redis-service

2）在reddis-service下创建6个文件夹：

sudo mkdir redis-7000 redis-7001 redis-7002 redis-7003 redis-7004 redis-7005

注：要让集群正常工作至少需要3个主节点,在这里我们要创建6个redis节点, 其中三个为主节点(master),三个为从节点(slave),对应的redis节点的ip和端口对应关系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
3）复制redis3.0.2下的redis.conf 到上一级目录的redis-service
4）修改文件名：

sudo mv redis.conf redis-cluster.conf dss@dss:/usr/local/redis-service$ ls redis-7000redis-7002redis-7004redis-cluster.conf redis-7001redis-7003redis-7005

5）复制redis-cluster.conf 分别到这六个文件夹内：
6）分别修改每个文件夹内的配置文件：
修改命令：

/usr/local/redis-service/redis-7000$ sudo vim redis-cluster.conf

修改内容例如：redis-7000:

【redis集群配置】port 7000
daemonize yes
pidfile redis-7000.pid
cluster-enabled yes
cluster-config-file nodes-7000.conf
cluster-node-timeout 15000 #看情况而定,尽量保持每台机子的原数据
appendonly yes

7）复制 redis-server 到/usr/local/redis-service/：

/usr/local/redis-3.0.2/src$ sudo cp redis-server /usr/local/redis-service/

8）执行redis：

/usr/local/redis-service$ sudo ./redis-server redis-7000/redis-cluster.conf & /usr/local/redis-service$ sudo ./redis-server redis-7001/redis-cluster.conf & /usr/local/redis-service$ sudo ./redis-server redis-7002/redis-cluster.conf & /usr/local/redis-service$ sudo ./redis-server redis-7003/redis-cluster.conf & /usr/local/redis-service$ sudo ./redis-server redis-7004/redis-cluster.conf & /usr/local/redis-service$ sudo ./redis-server redis-7005/redis-cluster.conf &

注：&符号是为了在执行时不占用本窗口！如果不加，你可以试试（手动滑稽
这样就成功启动了redis
3.安装集群工具： 1）安装ruby及交互环境：

/usr/local$ sudo apt-get install ruby /usr/local$ sudo apt-get install irb /usr/local$ sudo apt-get install ri

2）安装rubygems(必须安装,否则无法启动集群命令)
RubyGems 旨在方便地管理 gem 安装的工具,以及用于分发 gem 的服务器。这类似于Ubunt u 下的apt -get , Cent os 的 yum,Pyt hon 的 pip！！

sudo apt-get install rubygems

出现下面的情况的话：就只能手动编译安装了！

注意，选中 'ruby' 而非 'rubygems' ruby 已经是最新版 (1:2.3.0+1)。

官网下载rubygems安装包:https://rubygems.org/pages/download

cd /usr/local/src sudomkdir rubygems

移动到/usr/local/scr/rubygems/路径下！
解压安装包：

sudo unzip rubygems-2.7.7.zip cdrubygems-2.7.7

执行命令：

sudo ruby setup.rb

安装成功提示：

RubyGems installed the following executables: /usr/bin/gem2.3 /usr/bin/bundle2.3

通过gem安装redis：

sudo gem install redis Fetching: redis-4.0.1.gem (100%) Successfully installed redis-4.0.1 Parsing documentation for redis-4.0.1 Installing ri documentation for redis-4.0.1 Done installing documentation for redis after 1 seconds 1 gem installed

安装成功！！
进入/usr/local/redis-3.0.2/src,查找redis-trib.rb，并复制到redis-service

/usr/local/redis-3.0.2/src$ sudo cp redis-trib.rb /usr/local/redis-service/

启动集群命令：

sudo ./redis-trib.rb create --replicas 1 127.0.0.1:7000 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...

BINGO！！启动成功！！
