一、環境
系統 CentOS7.0 64位最小化安裝
redis1 172.16.1.46 6379,6380
redis2 172.16.1.47 6379,6380
redis3 172.16.1.47 6379,6380
二、基礎軟件安裝
[root@redis1 ~]# yum install vim wget tree ntp net-tools lsof gcc* -y [root@redis1 ~]# yum -y install gcc openssl-devel libyaml-devel libffi-devel readline-devel zlib-devel gdbm-devel ncurses-devel gcc-c++ automake autoconf libxml2* rubygem-nokogiri
三、安裝ruby
[root@redis1 ~]# yum install ruby rubygems ruby-devel -y #刪除ruby的默認源 [root@redis1 ~]# gem source --remove https://rubygems.org/ https://rubygems.org/ removed from sources #添加源 [root@redis1 ~]# gem sources -a https://ruby.taobao.org https://ruby.taobao.org added to sources #安裝rails [root@redis1 ~]# gem install rails #安裝redis和ruby的接口 [root@redis1 ~]# gem install redis
四、安裝redis
#下載redis
[root@redis1 ~]# wget http://download.redis.io/releases/redis-3.0.1.tar.gz
[root@redis1 ~]# tar xf redis-3.0.1.tar.gz -C /usr/local/
[root@redis1 ~]# ln -sv /usr/local/redis-3.0.1 /usr/local/redis
‘/usr/local/redis’ -> ‘/usr/local/redis-3.0.1’
[root@redis1 ~]# cd /usr/local/redis
[root@redis1 redis]# make
[root@redis1 redis]# make install
[root@redis1 ~]# cp /usr/local/redis/redis.conf /usr/local/redis6379.conf
#編輯6379的配置文件
[root@redis1 ~]# vim /usr/local/redis/redis6379.conf
port 6379
pidfile /var/run/redis6379.pid
dbfilename dump6379.rdb
appendfilename "appendonly-6379.aof"
cluster-config-file nodes-6379.conf
cluster-node-timeout 15000
cluster-enabled yes
appendonly yes
dir /usr/local/redis/data/6379
#編輯6380的配置文件
[root@redis1 ~]# cp /usr/local/redis/redis6379.conf /usr/local/redis/redis6380.conf
[root@redis1 ~]# sed -i 's#6379#6380#g' /usr/local/redis/redis6380.conf
