详解centos下搭建redis集群

必备的工具:

redis-3.0.0.tar

redis-3.0.0.gem (ruby和redis接口)

分析:

首先,集群数需要基数,这里搭建一个简单的redis集群(6个redis实例进行集群)。

在一台服务器上操作,因此仅需要6个不同的端口号即可。分别是:7001、7002、7003、7004、7005、7006。

步骤:

1、上传redis-3.0.0.tar到服务器(自己指定自己的软件目录),解压redis-3.0.0.tar。

2、安装c语言环境(安装centos之后,自带c语言环境)

yum install gcc-c++

3、进入到redis-3.0.0目录

make

4、安装redis到/usr/local/redis目录

make install PREFIX=/usr/local/redis

5、查看是否安装成功(出现bin目录即可)

6、前端启动redis(进入上图的bin目录)

./redis-server(开启)

./redis-cli shutdown(关闭)

7、后端启动

需要将redis解压之后的源码包中(redis-3.0.0目录下)的redis.conf文件拷贝到bin目录下

修改redis.conf文件,将daemonize改为yes先要使用vim redis.conf

使用命令后端启动redis

bin目录下执行 ./redis-server redis.conf

查看是否启动成功

关闭后端启动的方式:

./redis-cli shutdown

以上是单独的redis安装,接下来搭建集群!

安装ruby

yum install ruby

yum install rubygems

将以下文件上传到linux系统

redis-3.0.0.gem (ruby和redis接口)

进入该目录执行:gem install redis-3.0.0.gem

将redis-3.0.0包下src目录中的以下文件拷贝到/usr/local/redis/redis-cluster/

前提:先新建一个redis-cluster目录

搭建集群最少也得需要3台主机,如果每台主机再配置一台从机的话,则最少需要6台机器。

端口设计如下:7001-7006

第一步:复制出一个7001机器

进入/usr/local/redis/目录执行 cp bin ./redis-cluster/7001 –r

第二步:如果存在持久化文件,则删除

rm -rf appendonly.aof dump.rdb

第三步:设置集群参数

第四步:修改端口

第五步:复制出7002-7006机器

给出我桌面系统下的目录结构:

接下来设置一键启动全部redis或者关闭redis群:

首先,新建一个文件,可以用vim打开一个不存在的文件,然后保存就存在了。(上图的start-all.sh和shutdow-all.sh就是我新建的)

start-all.sh:

cd 7001

./redis-server redis.conf

cd ..

cd 7002

./redis-server redis.conf

cd ..

cd 7003

./redis-server redis.conf

cd ..

cd 7004

./redis-server redis.conf

cd ..

cd 7005

./redis-server redis.conf

cd ..

cd 7006

./redis-server redis.conf

cd ..

shutdow-all.sh:

cd 7001

./redis-cli -p 7001 shutdown

cd ..

cd 7002

./redis-cli -p 7002 shutdown

cd ..

cd 7003

./redis-cli -p 7003 shutdown

cd ..

cd 7004

./redis-cli -p 7004 shutdown

cd ..

cd 7005

./redis-cli -p 7005 shutdown

cd ..

cd 7006

./redis-cli -p 7006 shutdown

cd ..

接下来修改那两个文件权限,设置其为可启动的脚本文件

chmod u+x start-all.sh

chmod u+x shutdown-all.sh

接下来用ruby连接这几个集群,进行管理

则代表成功了!

测试一下,进入7001目录执行:./redis-cli -h 192.168.242.137 -p 7001 –c
