redis离线集群安装

Posted 2021-02-17 zhoufly

用一个叫redis-trib.rb的ruby脚本。redis-trib.rb是redis官方推出的管理redis集群的工具，集成在redis的源码src目录下（redis-xxx/src/）。是基于redis提供的集群命令封装成简单、便捷、实用的操作工具。redis-trib.rb是redis作者用ruby完成的。所以redis集群需要先安装ruby环境。

这是在线安装步骤

Redis-cluster集群需要使redis-trib.rb脚本来管理集群，redis-trib.rb脚本是使用ruby语言编写的。

 

搭建集群同时需要搭建6台redis服务器，其中3台主机、3台从机。端口分别为7001~7006。

 

第一步：搭建ruby环境

[root@bogon bin]# yum install -y ruby

[root@bogon bin]# yum install -y rubygems

 

第二步：上传ruby和redis的接口程序

 

 

第三步：安装ruby和redis的接口

[root@bogon ~]# gem install redis-3.0.0.gem

 

第四步：复制redis-trib.rb脚本到/usr/local/redis-cluster目录下

[root@bogon ~]# mkdir /usr/local/redis-cluster

[root@bogon ~]# cp /root/redis-3.0.0/src/redis-trib.rb /usr/local/redis-cluster/

 

第五步：复制/usr/local/redis/bin到/usr/local/redis-cluster/下，并改名为7001

[root@bogon redis-cluster]# cp /usr/local/redis/bin ./7001 –r

 

第六步：修改7001目录下的redis.conf文件，主要修改端口和集群配置。

port 7001

cluster-enabled yes

 

 

 

第七步：复制7001目录为7002~7006，然后修改端口

Cp 7001/ 7002 -r

Cp 7001/ 7003 -r

......

第八步：启动7001~7006这6个redis服务器

编辑启动脚本

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 ..

 

第九步：创建集群

[root@bogon redis-cluster]# ./redis-trib.rb create --replicas 1 192.168.242.129:7001 192.168.242.129:7002 192.168.242.129:7003 192.168.242.129:7004 192.168.242.129:7005  192.168.242.129:7006 >>> Creating cluster Connecting to node 192.168.242.129:7001: OK Connecting to node 192.168.242.129:7002: OK Connecting to node 192.168.242.129:7003: OK Connecting to node 192.168.242.129:7004: OK Connecting to node 192.168.242.129:7005: OK Connecting to node 192.168.242.129:7006: OK >>> Performing hash slots allocation on 6 nodes...

1.1 连接集群

命令：./redis-cli –h 127.0.0.1 –p 7001 –c

注意：-c 连接redis集群

[root@localhost-0723 redis]# ./redis-cli -p 7006 -c 127.0.0.1:7006> set key1 123 -> Redirected to slot [9189] located at 127.0.0.1:7002 OK 127.0.0.1:7002>

 

1.2 查看集群的命令

• 查看集群状态

127.0.0.1:7003> cluster info cluster_state:ok cluster_slots_assigned:16384 cluster_slots_ok:16384 cluster_slots_pfail:0 cluster_slots_fail:0 cluster_known_nodes:6 cluster_size:3 cluster_current_epoch:6 cluster_my_epoch:3 cluster_stats_messages_sent:926 cluster_stats_messages_received:926

 

• 查看集群中的节点：

这是离线安装

离线步骤和在线相差不大只是，需要离线安装，ruby,rubygems,openssl,zlib-devel

安装redis集群的环境,环境安装完了，集群安装是一样的

依赖包 redis-3.2.1.gem

　　    openssl-1.0.1s.tar.gz

　　　rubygems-2.4.2.tgz

           ruby-2.3.0.tar.gz

安装ruby: 

　　　tar -zxvf ruby-2.3.0.tar.gz

　　　./configure --prefix=/home/hadoop/opt/ruby

　　make

   　　make install
配置环境变量
　　vim .bash_profile
　　export PATH=$JAVA_HOME/bin:$PATH:/home/hadoop/software/ruby/bin
　　source .bash_profile
查看版本
　　ruby -v

安装rubygens

　　tar -zxvf rubygems-2.4.2.tgz
　　cd rubygems-2.4.2
　　ruby setup.rb

安装 redis与ruby接口

gem install redis-3.2.1.gem

出现报错

ERROR: Loading command: install (LoadError)
 cannot load such file -- zlib
ERROR: While executing gem ... (NoMethodError)
    undefined method `invoke_with_build_args\' for nil:NilClass

需先安装 zlib-devel 不然下面的make不能编译

yum -y install zlib-devel（离线安装这个包也要离线安装 ，暂且在线安装 zlib-debel）

 

进入ruby源码文件夹,安装ruby自身提供的zlib包

 

cd ruby-2.3.0/ext/zlib

ruby ./extconf.rb

make

make install

安装zlib包成功

 

在次安装

gem install redis-3.2.1.gem 

报错：

 

ERROR: While executing gem ... (Gem::Exception)  

Unable to require openssl, install OpenSSL and rebuild ruby (preferred) or use non-HTTPS sources
