使用ruby进行redis集群搭建

使用源码安装redis，在官网上下载3.0以后的版本。

(1)确保系统安装zlib,否则gem install会报(no such file to load -- zlib)

 

1. #download:zlib-1.2.6.tar  

2. ./configure  

3. make  

4. make install  

(2)安装ruby

1. # ruby1.9.2   

2. cd /home/searat/ruby  

3. ./configure -prefix=/usr/local/ruby  

4. make  

5. make install  

6. cp ruby /usr/local/bin  

(3)安装rubygem

1. # rubygems-1.8.16.tgz  

2. cd /home/searat/gem  

3. ruby setup.rb  

4. cp bin/gem /usr/local/bin  

(4)安装gem-redis

1. gem install redis --version 3.0.0  

    

 

wget http://rubygems.org/gems/redis/versions/3.0.0  

1. gem install -l /home/searat/redis-3.0.0.gem  

接下对redis目录做处理

使用源码安装后目录如下：

-bash-4.1$ tree -L 2 /home/searat/redis

/home/searat/redis

├── bin

│   ├── dump.rdb

│   ├── redis-benchmark

│   ├── redis-check-aof

│   ├── redis-check-dump

│   ├── redis-cli

│   ├── redis-sentinel -> redis-server

│   └── redis-server

├── conf

│   ├── dump.rdb

│   └── redis.conf

├── log

│   └── redis.log

└── redis_6379

从源码包中复制redis-trib.rb到/home/searat/redis/bin下，另外从源码包中找到create-cluster脚本，复制到/home/searat/redis/bin下。

若在单台服务器上使用create-cluster创建redis集群，直接执行create-cluster脚本即可。

若在两台或者更多台服务器上创建redis集群，可以改写create-cluster脚本

-bash-4.1$ cat create-cluster 
#!/bin/bash
PORT=$2   #端口号可以自己随意指定
PORTNUM=3 #定义端口号的个数
REPLICAS=1
REDIS_HOME=/home/searat/redis
HOST1=192.168.1.101
HOST2=192.168.1.102
HOSTS="$HOST1 $HOST2"
declare -A HOSTGROUP  #定义一个数组用来存放IP:PORT形式的数据，在创建集群时使用
i=1
if [ "$1" == "start" ]
then
    while [ $PORTNUM -gt "0" ]; do
        echo "Starting 127.0.0.1:$PORT"
        $REDIS_HOME/bin/redis-server ../conf/redis_$PORT.conf
PORT=$((PORT+1))
PORTNUM=$((PORTNUM-1))
    done
    exit 0
fi
if [ "$1" == "stop" ]
then
    while [ $PORTNUM -gt "0" ]; do
        echo "Stopping 127.0.0.1:$PORT"
        $REDIS_HOME/bin/redis-cli -p $PORT shutdown nosave
        PORT=$((PORT+1))
        PORTNUM=$((PORTNUM-1))
    done
    exit 0
fi
if [ "$1" == "create" ]
then
    while [ $PORTNUM -gt "0" ]; do
        for host in $HOSTS
            do
                HOSTGROUP[$i]=$host:$PORT
                i=`expr $i + 1`
            done
        PORT=$((PORT+1))
        PORTNUM=$((PORTNUM-1))
    done
    echo ${HOSTGROUP[*]}
    $REDIS_HOME/bin/redis-trib.rb create --replicas 1 ${HOSTGROUP[*]}
    exit 0
fi
if [ "$1" == "clean" ]
then
    rm -rf ../log/*.log
    rm -rf ../data/appendonly*.aof
    rm -rf ../data/dump*.rdb
    rm -rf ../data/nodes*.conf
    exit 0
fi
echo "Usage: $0 [start|create|stop|clean"
echo "start       -- Launch Redis Cluster instances."
echo "create      -- Create a cluster using redis-trib create."
echo "stop        -- Stop Redis Cluster instances."
echo "clean       -- Remove all instances data, logs, configs."

至于redis_6379.conf、redis_6380.conf这些配置文件，可以提前配置好，也可以在create-cluster中继续追加自动生成配置文件的代码。

redis集群启停：/home/searat/redis/bin/create-cluster start/stop 6379

创建集群：/home/searat/redis/bin/create-cluster create 6379

如果提示如下信息，则证明创建成功：

[OK] All nodes agree about slotsconfiguration.

>>>Check for open slots...

>>>Check slots coverage...

[OK] All 16384 slots covered.

验证Master、Slave信息：

/home/searat/redis/bin/redis-cli -p $PORT cluster nodes | head -30
