Redis3.2.8集群部署
第一步：安装redis
wget http://download.redis.io/releases/redis-3.2.8.tar.gz
tar xfredis-3.2.8.tar.gz
cd redis-3.2.8/
make --编译安装
make install #将可执行文件拷贝到/usr/local/bin目录下
也可以PREFIX=“”指定目录
makePREFIX=/some/other/directory install #指定二进制命令目录
cdredis-3.2.8/
cp redis-3.2.8/utils/redis_init_script/etc/init.d/redis #复制启动脚本
编辑
vi/etc/rc.d/init.d/redis，并在文档第二行添加# chkconfig: 2345 8090。如果/usr/local/redis/bin中没有redis-server和redis-cli文件的话，我们要在我们的安装目录下复制一个过来。否则服务启动时找不到redis-server
在$EXEC $CONF后面加$
mkdir /etc/redis
cpredis.conf /etc/redis/6379.conf
启动脚本
推荐在生产环境中使用启动脚本方式启动redis服务。启动脚本redis_init_script 位于位于Redis的 /utils/ 目录下。
#大致浏览下该启动脚本，发现redis习惯性用监听的端口名作为配置文件等命名，我们后面也遵循这个约定。
#redis服务器监听的端口
REDISPORT=6379
#服务端所处位置，在make install后默认存放与`/usr/local/bin/redis-server`，如果未make install则需要修改该路径，下同。
EXEC=/usr/local/bin/redis-server
#客户端位置
CLIEXEC=/usr/local/bin/redis-cli
#Redis的PID文件位置
PIDFILE=/var/run/redis_${REDISPORT}.pid
#配置文件位置，需要修改
CONF="/etc/redis/${REDISPORT}.conf"
第二步：集群配置
创建redis节点
测试我们选择2台服务器，分别为：192.168.100.11，192.168.100.15.每分服务器有3个节点。
在192.168.100.11上创建三个节点
mkdir -p /usr/local/redis-cluster
cd redis-cluster
mkdir 7000 7001 7002
复制redis.conf到7000 7001 7002目录下并修改配置文件端口
redis-server是从redis的安装目录中的src里copy过来就好 redis.conf内容如下； #======================================# port 6379 #不同目录，这里端口对应不同 cluster-enabled yes #开启集群功能 cluster-config-file nodes.conf #节点配置文件，这个文件是服务启动时自己配置创建的 cluster-node-timeout 5000 appendonly yes
mkdir /usr/local/redis-cluster
rsync -avz /usr/local/redis-cluster/ [email protected]:/usr/local/redis-cluster/
在192.168.100.11修改完成节点，通过rsync同步到192.168.100.15上。
第三步：创建集群

第四步：测试
使用redis-cli 首先登入7000这个端口的redis服务 ./redis-cli -c -h 192.168.100.11 -p 7000 192.168.100.11:7000> set name andyhua.chen 在192.168.100.15上登录7002端口 ./redis-cli -c -h 192.168.100.15 -p 7002 192.168.100.15:7002> get name #如果没有集群的话，这里肯定是没有的，现在则出现如下情况 -> Redirected to slot [5798] located at 192.168.100.11:7000 "andyhua.chen"
