redis集群模式,windows搭建redis集群

3. redis安装(1) 检查依赖环境（Redis是C语言开发，编译依赖gcc环境）

gcc

[root@i-tmzabnvr /]# gcc -v

gcc的安装

[ root @ I-tmzabnvr/] # sudoyuminstall-ygcc

(2) 将安装redis-4.0.14.tar.gz包复制到/usr/local/nlp目录，并解压。

下载

[ root @ I-tmzabnvrredis ] # wget http://download.redis.io/releases/redis-4.0.14.tar.gz

解冻

[ root @ I-tmzabnvrredis ] # tar-zxvf redis-4.0.14.tar.gz

(3) 编译文件

编译程序

[ root @ I-tmzabnvrredis-4.0.14 ] # make

hint : it ' sagoodideatorun ' maketest '； )编译成功。

(4) 安装

安装

[ root @ I-tmzabnvrredis-4.0.14 ] # make prefix=/data/software/redis/redis-main安装

创建命令软链接

[ root @ I-tmzabnvrredis-4.0.14 ] # ln-SV/data/software/redis/redis-main /昏迷声学/redis-* /usr/s昏迷声学

4 .群集配置Redis最小群集计划至少需要三个主节点。在此测试部署具有3个主服务器和3个从服务器的6节点群集。计划在一台计算机上模拟群集、节点端口8100、8101、8102、8103、8104和8105

(1) 创建节点目录

创建一个新目录，以及以下指定了redis实例端口号的目录：

[ root @ I-tmzabnvrredis-cluster ] # mkdir/data/software/redis/redis-cluster/nodes-8100

[根@ I-tmzabnvrredis-cluster ] # mkdir/data/software/redis/redis-cluster/nodes-8101

[ root @ I-tmzabnvrredis-cluster ] # mkdir/data/software/redis/redis-cluster/nodes-8102

[ root @ I-tmzabnvrredis-cluster ] # mkdir/data/software/redis/redis-cluster/nodes-8103

[ root @ I-tmzabnvrredis-cluster ] # mkdir/data/software/redis/redis-cluster/nodes-8104

[ root @ I-tmzabnvrredis-cluster ] # mkdir/data/software/redis/redis-cluster/nodes-8105

(2) 创建配置文件

在每个节点目录中创建文件redis.conf。

[ root @ I-tmzabnvrredis-cluster ] # CP redis.conf redis-cluster/nodes-8100

[ root @ I-tmzabnvrredis-cluster ] # CP redis.conf redis-cluster/nodes-8101

[ root @ I-tmzabnvrredis-cluster ] # CP redis.conf redis-cluster/nodes-8102

[ root @ I-tmzabnvrredis-cluster ] # CP redis.conf redis-cluster/nodes-8103

[ root @ I-tmzabnvrredis-cluster ] # CP redis.conf redis-cluster/nodes-8104

[ root @ I-tmzabnvrredis-cluster ] # CP redis.conf redis-cluster/nodes-8105

*(3)进入节点并更改配置文件*

详细配置请参阅附件redis-8100.conf

[ root @ I-tmzabnvrredis-cluster ] # vino des-8100/redis-8100.con

f
[root@i-tmzabnvr redis-cluster]# vi nodes-8100/redis-8101.conf
[root@i-tmzabnvr redis-cluster]# vi nodes-8100/redis-8102.conf
[root@i-tmzabnvr redis-cluster]# vi nodes-8100/redis-8103.conf
[root@i-tmzabnvr redis-cluster]# vi nodes-8100/redis-8104.conf
[root@i-tmzabnvr redis-cluster]# vi nodes-8100/redis-8105.conf

(4) 配置redis开机自动启动

详细配置见附件redis-8100.txt
[root@i-tmzabnvr /]# vi /etc/init.d/redis-8100
[root@i-tmzabnvr /]# vi /etc/init.d/redis-8101
[root@i-tmzabnvr /]# vi /etc/init.d/redis-8102
[root@i-tmzabnvr /]# vi /etc/init.d/redis-8103
[root@i-tmzabnvr /]# vi /etc/init.d/redis-8104
[root@i-tmzabnvr /]# vi /etc/init.d/redis-8105

配置可执行权限
[root@i-tmzabnvr /]# chmod 764 /etc/init.d/redis-8100
[root@i-tmzabnvr /]# chmod 764 /etc/init.d/redis-8101
[root@i-tmzabnvr /]# chmod 764 /etc/init.d/redis-8102
[root@i-tmzabnvr /]# chmod 764 /etc/init.d/redis-8103
[root@i-tmzabnvr /]# chmod 764 /etc/init.d/redis-8104
[root@i-tmzabnvr /]# chmod 764 /etc/init.d/redis-8105

注册系统服务
[root@i-tmzabnvr /]# chkconfig –add redis-8100
[root@i-tmzabnvr /]# chkconfig –add redis-8101
[root@i-tmzabnvr /]# chkconfig –add redis-8102
[root@i-tmzabnvr /]# chkconfig –add redis-8103
[root@i-tmzabnvr /]# chkconfig –add redis-8104
[root@i-tmzabnvr /]# chkconfig –add redis-8105

(5) 启动redis-cluster

启动集群
[root@i-tmzabnvr redis-cluster]# service redis-8100 start && service redis-8101 start && service redis-8102 start && service redis-8103 start && service redis-8104 start && service redis-8105 start

停止集群
[root@i-tmzabnvr redis-cluster]# service redis-8100 stop && service redis-8101 stop && service redis-8102 stop && service redis-8103 stop && service redis-8104 stop && service redis-8105 stop

5. 创建集群修改redis-trib.rb
原来：@r = Redis.new(:host => @info[:host], :port => @info[:port], :timeout => 60)
修改：@r = Redis.new(:host => @info[:host], :port => @info[:port], :timeout => 60, :password => “Oracle123”) 创建集群
./redis-trib.rb create –replicas 1 223.202.199.63:8100 223.202.199.63:8101 223.202.199.63:8102 223.202.199.63:8103 223.202.199.63:8104 223.202.199.63:8105

使某个节点崩溃
[root@i-tmzabnvr redis-cluster]# ./redis-trib.rb check 223.202.199.63:8100 查看集群状态
./redis-trib.rb check 10.168.14.46:8100 添加新节点为主服

集群数据不为空，Node 10.168.14.46:8100 is not empty

[uaren@yrz-redis01 redis-4.0.14]$ ./src/redis-trib.rb create --replicas 1 10.168.14.46:8100 10.168.14.46:8101 10.168.14.47:8200 10.168.14.47:8201 10.168.14.48:8300 10.168.14.48:8301[ERR] Node 10.168.14.46:8100 is not empty. Either the node already knows other nodes (check with CLUSTER NODES) or contains some key in database 0.

清空数据，在将每个节点下aof、rdb、nodes.conf本地备份文件删除，重新创建即可成功
