centos 7.4 + redis 4.0.9 cluster + make详解大数据

• 大数据

os: centos7.4
redis:4.0.9
ruby:2.3.4

ip 规划

redis1    192.168.56.101 
redis2    192.168.56.102

用两台虚拟机模拟6个redis节点。
分别为
192.168.56.101 的 9001、9002、9003 端口，
192.168.56.102 的 9001、9002、9003 端口。

os依赖包

# yum install gcc gcc-c++ openssl openssl-devel zlib zlib-devel tcl tcl-devel iftop sysstat telnet tree curl lrzsz

下载、编译、安装

IT虾米网
或者直接用wget
wget IT虾米网

redis1、redis2 两个节点都需要操作

# mkdir -p /usr/redis 
# cd /usr/redis 
# wget http://download.redis.io/releases/redis-4.0.9.tar.gz 
# tar -zxvf ./redis-4.0.9.tar.gz 
# cd redis-4.0.9 
# make 
# make test 
# make install

redis1 节点上操作，创建 cluster data 目录

# mkdir -p /usr/redis/redis-cluster-data 
# cd /usr/redis/redis-cluster-data 
# mkdir -p 9001 9002 9003

redis2 节点上操作，创建 cluster data 目录

# mkdir -p /usr/redis/redis-cluster-data 
# cd /usr/redis/redis-cluster-data 
# mkdir -p 9001 9002 9003

redis1、redis2 两个节点都需要操作
创建bin目录，添加到PATH里

# cd /usr/redis/redis-4.0.9 
# mkdir bin 
# cd src 
# cp mkreleasehdr.sh redis-benchmark redis-check-aof redis-check-rdb redis-cli redis-server redis-sentinel redis-trib.rb ../bin 
# vi /etc/profile 
PATH=/usr/redis/redis-4.0.9/bin:$PATH 
 
# echo $PATH 
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin 
# source /etc/profile 
# echo $PATH 
/usr/redis/redis-4.0.9/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin

redis cluster 配置

redis1 的 9001 9002 9003 目录下，
redis2 的 9001 9001 9003 目录下都需要创建 redis.conf

$ cd /usr/redis/redis-cluster-data/9001 
$ vi redis.conf 
#监听port 
port 9001 
#监听ip 
bind 192.168.56.101

#开启集群

#集群的配置文件

#请求超时,默认15秒，可自行设置 
cluster-node-timeout 15000 
#aof模式 
appendonly yes 
#aof模式文件 
appendfilename "appendonly.aof" 
#aof同步

#日志层级分为4个等级：debug verbose notice warning

创建redis集群

执行 redis-trib.rb 前必须安装ruby >= 2.2.2.

# yum install ruby ruby-devel ruby-libs rubygems rpm-build 
# gem install redis 
Fetching: redis-4.0.1.gem (100%) 
ERROR:  Error installing redis: 
    redis requires Ruby version >= 2.2.2.

默认的centos 7.4 yum源只支持到 ruby 2.0.0。所有上面的yum install 就不要执行了，我已经帮大家采坑了。
参考一哥们的解决办法：
IT虾米网
先安装rvm(rvm : Ruby enVironment Manager)，再把ruby版本提升至2.3.4，中间有错误根据错误提示处理就可以了。
1.安装curl

# yum install curl

2.安装rvm

# curl -L get.rvm.io | bash -s stable

3.解压rvm

# cd /usr/local/rvm/archives 
# ls -l 
# tar -zxvf ./rvm-1.29.3.tgz 
# source /usr/local/rvm/archives/rvm-1.29.3/scripts/rvm

4.查看rvm库中已知的ruby版本

# rvm list known

5.安装一个ruby版本

# rvm install 2.3.4 
Searching for binary rubies, this might take some time. 
Found remote file https://rvm_io.global.ssl.fastly.net/binaries/centos/7/x86_64/ruby-2.3.4.tar.bz2

ruby-2.3.4 - #generating default wrappers.......

6.使用一个ruby版本

# rvm use 2.3.4

7.设置默认版本

8.卸载一个已知版本

# rvm remove 2.0.0 
# ruby --version 
ruby 2.3.4p301 (2017-03-30 revision 58214) [x86_64-linux]

9.安装redis依赖

# 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
