开始部署之前，务必先看最后一条
- 从官网下载和编译redis安装包
$ wget http://download.redis.io/releases/redis-3.2.5.tar.gz
$ tar xzf redis-3.2.5.tar.gz
$ cd redis-3.2.5
$ make
- 配置redis
创建redis.conf, 内容如下
port 7000
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes
如果你不想做持久化的话，appendonly yes 改为 appendonly no,假设我们部署3个redis nodes, 那么需要创 建6个redis实例，其中3个node为master另外3个nodes的slave;
mkdir cluster-test
cd cluster-test
mkdir 7000 7001 7002 7003 7004 7005
将redis.conf分别拷贝一份到这6个文件夹下，保证这6个目录下的redis.conf的port 分别为7000~7005
- 启动所有redis实例
分别进入六个目录，启动相应的redis-server
cd 7000
../redis-server ./redis.conf
cd ../7001
../redis-server ./redis.conf
cd ../7002
../redis-server ./redis.conf
cd ../7003
../redis-server ./redis.conf
cd ../7004
../redis-server ./redis.conf
cd ../7005
../redis-server ./redis.conf
- 安装redis-trib.rb运行环境
redis-trib.rb是ruby代码，所以先要安装ruby
yum install ruby
gem install redis -- 安装redis依赖
因为墙的问题，gem install redis 可能会失败，改用国内的源
gem sources --remove https://rubygems.org/ 删掉原来的源
gem sources -a https://gems.ruby-china.com/ 改用国内的源
gem sources -l 查看现有的源
gem install redis 安装redis依赖
- 创建集群
./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
- 注意的地方
使用redis-trib.rb构建集群,完成前不要配置密码
集群构建完再通过config set + config rewrite命令逐个实例设置密码
对集群设置密码，requirepass和masterauth都需要设置
-
各个节点密码都必须一致，否则Redirected就会失败
config set masterauth yourpasswd config set requirepass yourpasswd auth yourpasswd config rewrite -
如果提示一下错误，那么是redis依赖版本错误，移除当前redis依赖，安装指定版本即可
