LInux系统下搭建redis集群

一、准备

　首先安装C语言的编译环境

apt-get install   gcc
或者
apt-get install  build-essential

　　

一、下载redis编译安装

$ wget http://download.redis.io/releases/redis-4.0.10.tar.gz
$ tar xzf redis-4.0.10.tar.gz
$ cd redis-4.0.10
$ make //编译

在编译时出现以下错误：

1）、

cd src && make all
make[1]: Entering directory '/home/ubuntu/redis-4.0.11/src'
    CC adlist.o
/bin/sh: 1: cc: not found
Makefile:228: recipe for target 'adlist.o' failed
make[1]: *** [adlist.o] Error 127
make[1]: Leaving directory '/home/ubuntu/redis-4.0.11/src'
Makefile:6: recipe for target 'all' failed
make: *** [all] Error 2

解决办法：sudo apt-get install gcc

　　

2）、

cd src && make all
make[1]: Entering directory '/home/ubuntu/redis-4.0.11/src'
    CC adlist.o
In file included from adlist.c:34:0:
zmalloc.h:50:10: fatal error: jemalloc/jemalloc.h: No such file or directory
 #include <jemalloc/jemalloc.h>
          ^~~~~~~~~~~~~~~~~~~~~
compilation terminated.
Makefile:228: recipe for target 'adlist.o' failed
make[1]: *** [adlist.o] Error 1
make[1]: Leaving directory '/home/ubuntu/redis-4.0.11/src'

解决办法：make MALLOC=libc

　　

二、进入到redis-4.0.10的src目录下，

执行编译命令：make install

三、安装ruby环境

命令>pt-get install ruby
命令>gem install redis

四、接下来我们创建6个配置文件，redis.6379.conf、redis.6379.conf、redis.6379.conf、redis.6379.conf、redis.6379.conf、redis.6379.conf，分别代表6个实例
配置如下：

port 6380
bing 10.211.55.8 #本机IP
daemonize  no 
appendonly yes
appendfilename "appendonly.6380.aof"
cluster-enabled yes
cluster-config-file nodes.6380.conf
cluster-node-timeout 15000
cluster-slave-validity-factor 10
cluster-migration-barrier 1
cluster-require-full-coverage yes

　　

五、分别启动六个服务

redis-server redis.6379.conf
redis-server redis.6380.conf
redis-server redis.6381.conf
redis-server redis.6382.conf
redis-server redis.6383.conf
redis-server redis.6384.conf

　六、创建集群

./redis-trib.rb create --replicas 1 10.211.55.8:6379 10.211.55.8:6380 10.211.55.8:6381 10.211.55.8:6382 10.211.55.9:6383 10.211.55.9:6384

　七、查看集群节点信息

./redis-trib.rb check 10.211.55.8:6379

elic@elic-Parallels-Virtual-Platform:~/桌面/redis-cluster$ ./redis-trib.rb check 10.211.55.8:6379

　　八、启动集群中的节点客户端

redis-cli -h 10.211.55.8 -p 6379 -c
