redis部署（單機3節點叢集）-手動安裝

注：

Ø  在配置時，本文檔以【使用者：redis/redis】、【目錄：/redis】為例進行說明

Ø  文檔中執行指令為藍色字型；配置檔案為粉色字型；重點标記為紅色字型

1.  叢集

1.1. 準備

此節需要使用root權限使用者安裝，每台機器隻需要執行一次

1.1.1.   安裝依賴包

如果不想一個個去确認依賴包，可以參考《redis部署（3台叢集）-自動安裝.docx》的【1.2.2.安裝依賴包】章節

1.1.1.1.         安裝ruby

Ø yum安裝方式

yum -y install ruby

yum -y install ruby-devel.x86_64

Ø rpm安裝方式

sudo rpm -ivh --forcecompat-readline5-5.2-17.1.el6.x86_64.rpm

sudo rpm -ivh --force ruby-libs-1.8.7.374-4.el6_6.x86_64.rpm

sudo rpm -ivh --force ruby-1.8.7.374-4.el6_6.x86_64.rpm

sudo rpm -ivh --force ruby-devel-1.8.7.374-4.el6_6.x86_64.rpm

1.1.1.2.         安裝rubygem

Ø yum安裝方式

yum -y install rubygems

Ø rpm安裝方式

sudo rpm -ivh --force ruby-irb-1.8.7.374-4.el6_6.x86_64.rpm

sudo rpm -ivh --force ruby-rdoc-1.8.7.374-4.el6_6.x86_64.rpm

sudo rpm -ivh --force rubygems-1.3.7-5.el6.noarch.rpm

有些系統預設沒有rubygems的包，可能需要手動安裝，先安裝好ruby-irb和ruby-rdoc，然後操作以下步驟

上傳rubygems-2.4.8.zip至/redis目錄

unzip rubygems-2.4.8.zip

cd rubygems-2.4.8

ruby setup.rb

1.1.1.3.         安裝redis.gem

上傳redis.gem至/redis目錄

gem install -l redis-3.2.2.gem

1.2.  安裝redis叢集

從此節開始使用普通使用者redis安裝

1.2.1.   redis安裝

上傳redis-3.0.5.tar.gz至/redis目錄

tar -zxvf redis-3.0.5.tar.gz

cd redis-3.0.5

make

make install PREFIX=/redis/redis

1.2.2.   配置步驟

1.2.2.1.         建立節點目錄

mkdir -p /redis/redis/cluster/7381/

mkdir -p /redis/redis/cluster/7382/

mkdir -p /redis/redis/cluster/7383/

mkdir -p /redis/redis/cluster/7384/

mkdir -p /redis/redis/cluster/7385/

mkdir -p /redis/redis/cluster/7386/

1.2.2.2.         複制配置檔案

cp /redis/redis-3.0.5/redis.conf /redis/redis/cluster/

1.2.2.3.         修改配置檔案

vi /redis/redis/cluster/redis.conf 

修改

---------------------------------------------------------------------------------------------------------------------------------

port 7381

appendonly yes

#daemonize yes

---------------------------------------------------------------------------------------------------------------------------------

#daemonize yes下方新增

---------------------------------------------------------------------------------------------------------------------------------

cluster-enabled yes

cluster-config-file/redis/redis/cluster/7381/nodes.conf

cluster-node-timeout 5000

---------------------------------------------------------------------------------------------------------------------------------

1.2.2.4.         複制配置檔案至各節點

#修改完redis.conf配置檔案中的這些配置項之後把這個配置檔案分别拷貝到7381/73812/7383/7384/7385/7386目錄下面

cp /redis/redis/cluster/redis.conf/redis/redis/cluster/7381/

cp /redis/redis/cluster/redis.conf/redis/redis/cluster/7382/

cp /redis/redis/cluster/redis.conf /redis/redis/cluster/7383/

cp /redis/redis/cluster/redis.conf/redis/redis/cluster/7384/

cp /redis/redis/cluster/redis.conf/redis/redis/cluster/7385/

cp /redis/redis/cluster/redis.conf/redis/redis/cluster/7386/

1.2.2.5.         修改各節點配置檔案端口

#拷貝完成之後要修改7381/73812/7383/7384/7385/7386目錄下面redis.conf檔案中的port參數和cluster-config-file參數，分别改為對應的檔案夾的名稱

sed -i "s/7381/7381/g"/redis/redis/cluster/7381/redis.conf

sed -i "s/7381/7382/g"/redis/redis/cluster/7382/redis.conf

sed -i "s/7381/7383/g"/redis/redis/cluster/7383/redis.conf

sed -i "s/7381/7384/g"/redis/redis/cluster/7384/redis.conf

sed -i "s/7381/7385/g"/redis/redis/cluster/7385/redis.conf

sed -i "s/7381/7386/g"/redis/redis/cluster/7386/redis.conf

1.2.2.6.         建立持久化目錄

cd /redis/redis/cluster

mkdir data

cd /redis/redis/cluster/data

mkdir 7381 7382 7383 7384 7385 7386

1.2.2.7.         啟動reids

#分别啟動這6個redis執行個體

cd /redis/redis/bin/

nohup ./redis-server /redis/redis/cluster/7381/redis.conf&

nohup ./redis-server /redis/redis/cluster/7382/redis.conf&

nohup ./redis-server /redis/redis/cluster/7383/redis.conf&

nohup ./redis-server /redis/redis/cluster/7384/redis.conf&

nohup ./redis-server /redis/redis/cluster/7385/redis.conf&

nohup ./redis-server /redis/redis/cluster/7386/redis.conf&

1.2.2.8.         确認啟動情況

#啟動之後使用指令檢視redis的啟動情況，每個端口會有一個程序

ps -ef|grep redis

1.2.2.9.         建立叢集

#建立叢集，讓上面的執行個體互相通訊(1表示為每個master配置設定一個salve)

cd /redis/redis-3.0.5/src/

./redis-trib.rb create --replicas 1 \

120.76.21.209:7381 \

120.76.21.209:7382 \

120.76.21.209:7383 \

120.76.21.209:7384 \

120.76.21.209:7385 \

120.76.21.209:7386

1.2.2.10.    确認節點資訊

執行以下指令可以檢視到節點資訊，存在3主3從：

./redis-cli -h 120.76.21.209 -p 7381 cluster nodes

1.2.3.   測試

進入任意一台的/redis/redis/bin

cd /redis/redis/bin

./redis-cli -h 120.76.21.209 -p 7381 -c

---------------------------------------------------------------------------------------------------------------------------------

crm89:/redis/redis/bin $ ./redis-cli -h 120.76.21.209-p 7381 -c

120.76.21.209:7381> set key 1

-> Redirected to slot [12539] located at120.76.21.209:7381

OK

120.76.21.209:7381> get key

"1"

120.76.21.209:7381> exit

---------------------------------------------------------------------------------------------------------------------------------

1.2.4.   啟動

cd /redis/redis/bin/

nohup ./redis-server /redis/redis/cluster/7381/redis.conf&

nohup ./redis-server /redis/redis/cluster/7382/redis.conf&

nohup ./redis-server /redis/redis/cluster/7383/redis.conf&

nohup ./redis-server /redis/redis/cluster/7384/redis.conf&

nohup ./redis-server /redis/redis/cluster/7385/redis.conf&

nohup ./redis-server /redis/redis/cluster/7386/redis.conf&

1.2.5.   停止

ps -ef|grep redis

kill 掉所有程序
