1、安裝配置redis的cluster集群

1.1環(huán)境準(zhǔn)備

六臺服務(wù)器

① 192.168.37.17：6379

② 192.168.37.27：6379

③ 192.168.37.37：6379

④ 192.168.37.47：6379

⑤ 192.168.37.57：6379

⑥ 192.168.37.67：6379

1.2 編譯安裝redis（六臺服務(wù)器相同）

安裝相關(guān)依賴庫：yum -y install gcc? automake autoconf libtool make zlib zlib-devel? tcl

切換目錄：cd /usr/local/src/

解包：tar xvf redis-4.0.14.tar.gz

切換目錄：cd redis-4.0.14

安裝：make PREFIX=/usr/local/redis install

復(fù)制配置文件：mkdir?/usr/local/redis/etc? ??cp /usr/local/src/redis-4.0.14/redis.conf??/usr/local/redis/etc/

創(chuàng)建軟連接：ln -sv /usr/local/redis/bin/redis-* /usr/bin/

創(chuàng)建用戶：groupadd -g 1500 redis && useradd -u 1500 -g 1500 redis -s /sbin/nologin

創(chuàng)建相關(guān)目錄：mkdir -pv /usr/local/redis/{etc,logs,data,run}

更改權(quán)限：chown redis.redis -R /usr/local/redis/

1.3 安裝集群管理工具 redis-trib.rb

yum安裝：yum install ruby rubygems -y

cp /usr/local/src/redis-4.0.14/src/redis-trib.rb /usr/bin/

版本較低無法使用：

刪除：rm -f /usr/bin/redis-trib.rb

1.4 解決 ruby 版本較低問題：

卸載ruby：yum remove ruby rubygems -y

刪除文件：rm -f /usr/bin/redis-trib.rb

下載2.5版本ruby：wget https://cache.ruby-lang.org/pub/ruby/2.5/ruby-2.5.5.tar.gz

解包：tar xf ruby-2.5.5.tar.gz

切換目錄：cd ruby-2.5.5

安裝：?./configuremake &&?make install

創(chuàng)建軟連接： cp /opt/redis-4.0.14/src/redis-trib.rb /usr/local/redis/bin/

啟動：redis-server /usr/local/redis/etc/redis.conf

1.6 創(chuàng)建 redis cluster 集群

創(chuàng)建：redis-trib.rb create? --replicas 1 192.168.37.17:6379? 192.168.37.27:6379 192.168.37.37:6379 192.168.37.47:6379 192.168.37.57:6379 192.168.37.67:6379
