1.安装ruby
wget https://cache.ruby-lang.org/pub/ruby/2.6/ruby-2.6.3.tar.gz tar xvf ruby-2.6.3.tar.gz cd ruby-2.6.3 ./configure --prefix=/usr/local/ruby make && make install
配置环境变量
vim /etc/profile
export PATH=$PATH:/usr/local/ruby/bin source /etc/profile ruby -v 查看ruby安装版本
2.其他软件依赖
安装zlib
wget http://zlib.net/zlib-1.2.11.tar.gz tar xvf zlib-1.2.11.tar.gz cd zlib-1.2.11 ./configure --prefix=/usr/local/zlib make && make install
安装openssl
yum install openssl openssl-devel
重新编译ruby
zlib报错
cd ruby-2.6.3/ext/zlib ruby extconf.rb //在操作下一步之前需要修改Makefile文件中的zlib.o: $(top_srcdir)/include/ruby.h,将$(top_srcdir)修改为../..如下 //zlib.o: ../../include/ruby.h //这一步如果不修改，make时会爆出另外一个错误 //make:*** No rule to make target `/include/ruby.h', needed by `zlib.o'. Stop make && make install
openssl报错
cd ruby-2.6.3/ext/openssl/ ruby extconf.rb //同样修改Makefile中的$(top_srcdir)为../.. make && make install
3.创建集群
cd /usr/local/ mkdir redis-cluster cd redis-cluster/ mkdir 7001 7002 7003 7004 7005 7006 wget https://rubygems.org/downloads/redis-4.1.2.gem gem install redis-4.1.2.gem
编辑配置文件
daemonize yes #开启后台运行
port 7001 #工作端口
bind 127.0.0.1
dir /usr/local/redis-cluster/7001/ #指定工作目录，rdb,aof持久化文件将会放在该目录下，不同实例一定要配置不同的工作目录
cluster-enabled yes #启用集群模式
cluster-config-file nodes-7001.conf #生成的集群配置文件名称，集群搭建成功后会自动生成，在工作目录下
cluster-node-timeout 5000 #节点宕机发现时间，可以理解为主节点宕机后从节点升级为主节点时间
appendonly yes #开启AOF模式
pidfile /var/run/redis_7001.pid #pid file所在目录
4.启动集群
启动redis
redis-server ./7001/redis_7001.conf redis-server ./7002/redis_7002.conf redis-server ./7003/redis_7003.conf redis-server ./7004/redis_7004.conf redis-server ./7005/redis_7005.conf redis-server ./7006/redis_7006.conf
