閑來無事自己做的關于redis-cluster集群的測試

redis的安裝

下載安裝包（這里使用的版本是：redis-3.2.9.tar.gz）

cd /home/download

tar -zxvf redis-3.2.9.tar.gz

mv redis-3.2.9 redis

創建所需要的以端口為區別的文件夾

mkdir cluster?

cd cluster && mkdir 7000 7001 7002 7003 7004 7005

cd /home/download/redis

cp redis.conf /home/download/cluster/7000

修改7000里面的配置文件

vim /home/download/cluster/7000/redis.conf

修改以下幾項

port 7000

daemonize yes

cluster-enabled yes

cluster-config-file nodes-7000.conf

cluster-node-timeout 5000

appendonly yes

分別復制到其余的文件夾下面，修改端口號和文件名稱一樣

安裝集群管理插件

redis-3.2.1.gem 網上下載一個 ?我這不是最新版本的

yum install ruby rubygems -y

gem install -l redis-3.2.1.gem

分別啟動6個redis

cd /home/download/redis/src

./redis-server /home/download/cluster/7000/redis.conf

./redis-server /home/download/cluster/7001/redis.conf

./redis-server /home/download/cluster/7002/redis.conf

./redis-server /home/download/cluster/7003/redis.conf

./redis-server /home/download/cluster/7004/redis.conf

./redis-server /home/download/cluster/7005/redis.conf

檢查啟動情況

pa-ef | grep redis

創建集群

./redis-trib.rb create --replicas 1 127.0.0.1:7000 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

(上面的‘1’表示為主的創建一個slave的)

致此，搭建成功

測試可用redis-cli -c -p 7001

127.0.0.1:7001> set name ceshi

OK

127.0.0.1:7001> get name

"ceshi"

斷點測試

去掉7000redis

[root@localhost src]# ./redis-cli -c -p 7004

"ceshi"

127.0.0.1:7004>?

可以取到值，再次查看狀態信息
