centos6.7 搭建 redis集群

一，准备工作

1，下载redis包 redis-3.2.0.tar.gz

2，下载 tcl8.6.5-src.tar.gz （针对tcl版本过低的centos系统）

二，创建redis用户

useradd redis

passwd redis 输入密码

三，安装

1，创建redis安装目录

mkdir -p /usr/local/redis

chown -R redis.redis /usr/local/redis

1，将redis安装包上传到/usr/local/redis目录并解压

3，进入 redis-3.2.0 文件夹编译安装（其实我觉得没必要再编译安装，直接进入src目录运行命令就可以）

编译安装过程中可能会出现一些错误 所以最好编译安装之前运行一下以下的命令

yum install ruby

yum install rubygems

wget https://rubygems.global.ssl.fastly.net/gems/redis-3.2.1.gem
gem install -l ./redis-3.2.1.gem

。。。过程中还会出现tcl版本过低的问题，在网上找资料升级一下就可以了

4，创建集群需要的目录并拷贝redis

mkdir -p /usr/local/cluster

mkdir -p /usr/local/cluster/7000

mkdir -p /usr/local/cluster/7001

mkdir -p /usr/local/cluster/7002

mkdir -p /usr/local/cluster/7003

mkdir -p /usr/local/cluster/7004

mkdir -p /usr/local/cluster/7005

cp -rf /usr/local/redis3.2.0/* /usr/local/cluster/7000/

cp -rf

/usr/local/redis3.2.0* /usr/local/cluster/7001/

cp -rf

/usr/local/redis3.2.0* /usr/local/cluster/7002/

cp -rf

/usr/local/redis3.2.0* /usr/local/cluster/7003/

cp -rf

/usr/local/redis3.2.0* /usr/local/cluster/7004/

cp -rf

/usr/local/redis3.2.0* /usr/local/cluster/7005/

5，修改配置文件redis.conf

vi /usr/local/cluster/7000/redis.conf

##修改配置文件中的下面选项

port 7000

daemonize yes

cluster-enabled yes

cluster-config-file nodes-7000.conf

cluster-node-timeout 5000

appendonly yes

#同样再对其它配置文件进行修改

vi /usr/local/cluster/7001/redis.conf

vi /usr/local/cluster/7002/redis.conf

vi /usr/local/cluster/7003/redis.conf

vi /usr/local/cluster/7004/redis.conf

vi /usr/local/cluster/7005/redis.conf

cd
/usr/local/cluster/7000/src

./redis-server ../redis.conf

6,创建redis集群

cd /usr/local/redis3.0/src

./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
