redis 集羣配置

redis 集羣配置

①，查看gcc是否安裝

gcc -v

沒有就安裝gcc

yum install gcc

 

②加壓redis文件並安裝

解壓 tar -zxvf redis-xxx.tar.gz

進入 cd redis-3.0.6

鍵入 make 進行安裝

將 redis-cli，redis-sentinel，redis-server 放入/usr/local/bin

這樣在任意目錄下就能啓動redis了

 

③新建redis_cluster 目錄

在redis_cluster 目錄下新建 7001,7002,7003,7004,7005,7006文件夾

cp redis.conf /redis_cluster/redis7001.conf

vim redis7001.conf

修改以下：

daemonize yes #後臺啓動

port 700x #修改端口號，從7001到7006

cluster-enabled yes #開啓cluster，去掉註釋

cluster-config-file nodes.conf

cluster-node-timeout 15000

appendonly yes

dir /redis-3.0.6/redis_cluster/700x #修改目錄，從7001到7006

bind 127.0.0.1

 

④redis-server redis700x.conf 啓動對應的redis

ps -ef|grep redis 若能看到下圖，說明前面配置成功

[root@localhost src]# ps -ef|grep redis
root      2304     1  0 20:08 ?        00:00:01 redis-server 127.0.0.1:7002 [cluster]
root      2328     1  0 20:15 ?        00:00:01 redis-server 127.0.0.1:7001 [cluster]
root      2334     1  0 20:15 ?        00:00:01 redis-server 127.0.0.1:7003 [cluster]
root      2341     1  0 20:15 ?        00:00:01 redis-server 127.0.0.1:7004 [cluster]
root      2349     1  0 20:17 ?        00:00:01 redis-server 127.0.0.1:7006 [cluster]
root      2355     1  0 20:17 ?        00:00:00 redis-server 127.0.0.1:7005 [cluster]
root      4576  2272  0 20:47 pts/0    00:00:00 grep redis

 

⑤ 安裝ruby環境：

yum install ruby

yum install rubygems

下載redis-3.2.2.gem（能夠到這篇博客裏下載）

放入 redis_cluster目錄，執行以下命令

gem install redis-3.2.2.gem

 

⑥使用redis-trib.rb建立集羣

./redis-trib.rb create --replicas 1 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005 127.0.0.1:7006

1. 看到以下狀況，表示成功

[root@localhost src]# ./redis-trib.rb create --replicas 1 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005 127.0.0.1:7006

⑦鏈接redis集羣客戶端

[root@localhost redis01]# ./redis-cli -c -p 7001

127.0.0.1:7001> set name andy

-> Redirected to slot [5798] located at 127.0.0.1:7002

OK

127.0.0.1:7002> get name

"andy"

127.0.0.1:7002>

 

 

⑧查看redis 集羣狀況

cluster nodes

127.0.0.1:7001> cluster nodes

（由於我手動中止了7003，而後又啓動了7003，全部7006變成了master，而7003在重啓後變成了slave）
