本文记录redis安装到集群搭建详细过程
环境
- Centos7
- 3主3从方式
- redis-3.2.12.tar.gz
搭建
安装redis
需要gcc环境来编译c，故先安装gcc
安装gcc
yum install gcc-c++
下载redis源码包上传到linux系统
解压、编译、安装
个人习惯源码包放到/usr/local/src下，在此直接解压
- 解压后进到解压目录编译
make - 指定安装目录进行安装
make install PREFIX=/usr/local/redis
执行命令时如下：
[root@mini2 redis]# make install PREFIX=/usr/local/redis
cd src && make install
make[1]: Entering directory `/usr/local/src/redis/src'
Hint: It's a good idea to run 'make test' ;)
INSTALL install
INSTALL install
INSTALL install
INSTALL install
INSTALL install
make[1]: Leaving directory `/usr/local/src/redis/src'它建议先make test，那就先test一下，执行make test，一切就绪后在次执行之前的安装命令
启动
把原解压目录下的redis.conf文件也可以复制到安装目录
/usr/local/redis下
先修改配置文件支持后台启动
daemonize yes[root@mini2 bin]# pwd
/usr/local/redis/bin
[root@mini2 bin]# ./redis-server redis.conf
[root@mini2 bin]# ./redis-cli -p 6379
127.0.0.1:6379> 集群的搭建
一般redis集群3主3从足够。故在此搭建一个伪分布式的集群，使用6个redis实例来模拟。 且redis的集群需要一个ruby程序来创建，故先安装ruby环境
安装ruby环境
yum install ruby
yum install rubygems在/usr/local/redis创建redis-cluster文件夹及配置6个实例
在该文件夹中创建6个redis实例，即6个conf配置文件，端口号从7001~7006

至少需要配置的信息如下：
bind 192.168.31.202
port 7001
daemonize yes
cluster-enabled yes
cluster-config-file nodes-7001.conf # 此处每个节点不能一样
创建集群的ruby脚本redis-trib.rb
把创建集群的ruby脚本redis-trib.rb（在redis源码解压目录下）复制到redis-cluster文件夹下
安装redis管理工具
- 下载ruby环境下Redis的驱动，考虑到兼容性，这里下载的是3.2.2版本：https://rubygems.org/gems/redis/versions/3.2.2
注意：下载在页面右下角相关连接一项中
- 把
redis-3.2.2.gem上传至服务器进行安装，这里放到redis-cluster中 - 安装
[root@mini2 bin]# gem install redis-3.2.2.gem
Successfully installed redis-3.2.2
Parsing documentation for redis-3.2.2
Installing ri documentation for redis-3.2.2
1 gem installed启动所有实例
- 这里创建一个脚本来同时启动六个，本脚本放在redis-cluster文件夹中
startall.sh
#!/bin/bash
echo 'start to setup redis7001'
../bin/redis-server redis7001.conf
echo 'start to setup redis7002'
../bin/redis-server redis7002.conf
echo 'start to setup redis7003'
../bin/redis-server redis7003.conf
echo 'start to setup redis7004'
../bin/redis-server redis7004.conf
echo 'start to setup redis7005'
../bin/redis-server redis7005.conf
echo 'start to setup redis7006'
../bin/redis-server redis7006.conf- 给予执行权限
chmod +777 startall.sh- 启动
./startall.sh利用工具创建集群
最后本次测试所有的文件结构如下：
[root@mini2 redis]# tree --charset ASCII
.

| |-- redis-3.2.2.gem
| |-- redis-benchmark
| |-- redis-check-aof
| |-- redis-check-dump

|-- redis.conf
|-- redis-trib.rb
`-- startall.sh创建集群,如下执行命令
[root@mini2 redis-cluster]# ./redis-trib.rb create --replicas 1 192.168.31.202:7001 192.168.31.202:7002 192.168.31.202:7003 192.168.31.202:7004 192.168.31.202:7005 192.168.31.202:7006

如下执行：注意加上-c表示连接集群，否则连不上
