linux
1. 安装
tar -zxvf redis-3.2.1.tar.gz
cd redis-3.2.1/
make test
cd redis-3.2.1/src/
make
make install
cd /usr/local/redis/bin
ll #查看安装后的文件，如有redis-server表明安装成功
cp -rf /home/gilbert/app/redis-3.2.1/redis.conf /usr/local/redis/ #复制redis.conf到安装目录
cd /usr/local/redis/
ll #查看是否复制成功
如出现以下错误
得先安装tcl
tar xzvf tcl8.6.1-src.tar.gz -C /usr/local/
cd /usr/local/tcl8.6.1/unix/
./configure
make
make install
2. redis命令
1）启动
cd /usr/local/redis/bin
./redis-server #启动redis
linux redis集群搭建
一 背景
用两台虚拟机模拟6个节点，一台机器3个节点，创建出3 master、3 salve 环境。
redis 采用 redis-3.2.1 版本。
两台虚拟机都是 CentOS ，
一台 CentOS（IP:192.168.1.128，三个端口7000，7001，7002），
一台 CentOS（IP:192.168.1.129，三个端口7003，7004，7005）
本人虚拟机如下图
二 安装前置条件
1. tcl
优先考虑yum安装
yum list tcl
yum install -y tcl
如果yum源里没有，刚从官网下载gz包安装。以安装到/home/gilbert/app/下为例
cd /home/gilbert/app/
tar xzvf tcl8.6.1-src.tar.gz -C /usr/local/
cd /usr/local/tcl8.6.1/unix/
./configure
make
make install
2. ruby
优先考虑yum安装
yum list ruby
yum install -y ruby
如果yum源里没有，刚从官网下载gz包安装。以安装到/home/gilbert/app/下为例
cd /home/gilbert/app/
tar -zxvf ruby-2.2.7.tar.gz
cd ruby-2.2.7
./configure
make test
make
make install
3. rubygems
优先考虑yum安装
yum list rubygems
yum install -y rubygems
如果yum源里没有，刚从官网下载gz包安装。以安装到/home/gilbert/app/下为例
cd /home/gilbert/app/
tar -zxvf rubygems-2.7.7.tgz
cd rubygems-2.7.7
ruby setup.rb
三 集群搭建
1.复制redis-trib.rb
cd /home/gilbert/app/
cd redis-3.2.1
cp src/redis-trib.rb /usr/local/bin/
2.创建 Redis 节点
1) 首先在 192.168.1.128 机器上 redis-3.2.1 目录下创建 redis_cluster 目录以及7000，7001，7002目录；
cd /home/gilbert/app/
cd redis-3.2.1
mkdir redis_cluster
cd redis_cluster
mkdir 7000
mkdir 7001
mkdir 7002
2) 将redis.conf拷贝到7000，7001和7002目录下
cp redis.conf redis_cluster/7001
cp redis.conf redis_cluster/7002
cp redis.conf redis_cluster/7003
3) 分别修改7000,7001和7002目录下redis.conf。需要修改的内容如下
port 7000 //端口7000,7001,7002
bind 192.168.1.128 //默认ip为127.0.0.1 需要改为其他节点机器可访问的ip 否则创建集群时无法访问对应的端口，无法创建集群
daemonize yes //redis后台运行
pidfile /var/run/redis_7000.pid //pidfile文件对应7000,7001,7002
cluster-enabled yes //开启集群 把注释#去掉
cluster-config-file nodes_7000.conf //集群的配置，配置文件首次启动自动生成 7000,7001,7002
cluster-node-timeout 15000 //请求超时 默认15秒，可自行设置
appendonly yes //aof日志开启 有需要就开启，它会每次写操作都记录一条日志
4）在192.168.1.129服务器重复以上3个步骤，但是目录分别为7003，7004和7005，redis.conf也修改为对应的7003，7004和7005
3.启动节点
1) 在 192.168.1.128 机器上启动
cd /home/gilbert/app/redis-3.2.1
redis-server redis_cluster/7000/redis.conf
redis-server redis_cluster/7001/redis.conf
redis-server redis_cluster/7002/redis.conf
2）在 192.168.1.129 机器上启动
cd /home/gilbert/app/redis-3.2.1
redis-server redis_cluster/7003/redis.conf
redis-server redis_cluster/7004/redis.conf
redis-server redis_cluster/7005/redis.conf
4. 检查 redis 启动情况
1) 在 192.168.1.128 机器上查看
ps -ef | grep redis
root 2608 1 2 05:38 00:00:00 redis-server 192.168.1.128:7000 [cluster]
root 2610 1 1 05:38 00:00:00 redis-server 192.168.1.128:7001 [cluster]
root 2616 1 1 05:38 00:00:00 redis-server 192.168.1.128:7002 [cluster]
root 2620 2544 0 05:38 pts/0 00:00:00 grep redis
netstat -tnlp | grep redis

tcp 0 0 192.168.1.128:17002 0.0.0.0:* LISTEN 2616/redis-server 1
2) 在 192.168.1.129 机器上查看
ps -ef | grep redis
root 2206 1 0 05:39 00:00:00 redis-server 192.168.1.129:7003 [cluster]
root 2208 1 0 05:39 00:00:00 redis-server 192.168.1.129:7004 [cluster]
root 2216 1 0 05:39 00:00:00 redis-server 192.168.1.129:7005 [cluster]
root 2221 2159 0 05:39 pts/0 00:00:00 grep redis
netstat -tnlp | grep redis

tcp 0 0 192.168.1.129:17004 0.0.0.0:* LISTEN 2208/redis-server 1

tcp 0 0 192.168.1.129:7005 0.0.0.0:* LISTEN 2216/redis-server 1
5.创建集群
1） 前置条件，安装了redis-3.2.1.gem并且redis安装到了gem
gem install -l /home/gilbert/app/redis-3.2.1.gem
gem isntall redis
2) 创建集群节点
cd /home/gilbert/app/redis-3.2.1
redis-trib.rb create --replicas 1 192.168.1.128:7000 192.168.1.128:7001 192.168.1.128:7002 192.168.1.129:7003 192.168.1.129:7004 192.168.1.129:7005

[OK] All nodes agree about slots configuration.

>>> Check slots coverage...
[OK] All 16384 slots covered. 6.集群验证
1） 在192.168.1.128服务器上连接7002端口节点
cd /home/gilbert/app/redis-3.2.1
redis-cli -h 192.168.1.128 -c -p 7002
192.168.1.128:7002>
2）在192.168.1.129服务器上连接7005端口节点
cd /home/gilbert/app/redis-3.2.1
redis-cli -h 192.168.1.129 -c -p 7005
192.168.1.129:7005> set hello word
-> Redirected to slot [866] located at 192.168.1.129:7003
OK
192.168.1.129:7003>
3) 在192.168.1.128服务器上命令窗口中获取key的内容，如可获取key为hello的内容为word，表明搭建成功
192.168.1.128:7002> get hello
-> Redirected to slot [866] located at 192.168.1.129:7003
"word"
192.168.1.129:7003> keys *
1) "hello"
