  參考:

  http://redis.io/topics/cluster-tutorial(主要是Creating a Redis Cluster using the create-cluster script部分)

  https://ruby.taobao.org/

  安裝一款不熟悉的軟件前先看INSTALL,README,這是習(xí)慣,生產(chǎn)上要建立普通用戶并調(diào)節(jié)適當參數(shù),下面是以root身份安裝運行.

  下載解壓并安裝redis

  make test提示需要更高版本的tcl,跳到安裝過程可能遇到的問題

  

wget http://download.redis.io/releases/redis-3.0.7.tar.gz
tar xf redis-3.0.7.tar.gz 
cd redis-3.0.7
mkdir -p /opt/redis
make test
make PREFIX=/opt/redis install

  復(fù)制兩個腳本到安裝的目錄

 

 cp ~/redis-3.0.7/src/redis-trib.rb /opt/redis/

  cp ~/redis-3.0.7/utils/create-cluster/create-cluster /opt/redis/1212

 

  根據(jù)實際修改/opt/redis/create-cluster.改動的地方有幾處

  a.增加了三個變量BASEDIR,BINDIR和DATADIR,

  b.修改相關(guān)命令路徑,

  c.start前,先進入DATADIR,start后,返回原目錄

  d.clean前,先進入DATADIR,start后,返回原目錄

  e.create的host由127.0.0.1改為192.168.1.194(不改有時會報Too many Cluster redirections)

  下面是修改后的shell

 

 #!/bin/bash

  # Settings

  PORT=30000

  TIMEOUT=2000

  NODES=6

  REPLICAS=1

  BASEDIR=/opt/redis

  BINDIR=$BASEDIR/bin

  DATADIR=$BASEDIR/data

 
  # You may want to put the above config parameters into config.sh in order to

  # override the defaults without modifying this script.

  if [ -a config.sh ]

  then

  source "config.sh"

  fi

  # Computed vars

  ENDPORT=$((PORT+NODES))

  if [ "$1" == "start" ]

  then

  cd $DATADIR

  while [ $((PORT  ENDPORT)) != "0" ]; do

  PORT=$((PORT+1))

  echo "Starting $PORT"

  $BINDIR/redis-server --port $PORT --cluster-enabled yes --cluster-config-file nodes-${PORT}.conf --cluster-node-timeout $TIMEOUT --appendonly yes --appendfilename appendonly-${PORT}.aof --dbfilename dump-${PORT}.rdb --logfile ${PORT}.log --daemonize yes

  done

  cd -

  exit 0

  fi

  if [ "$1" == "create" ]

  then

  HOSTS=""

  while [ $((PORT  ENDPORT)) != "0" ]; do

  PORT=$((PORT+1))

  HOSTS="$HOSTS 192.168.1.194:$PORT"

  done

  $BASEDIR/redis-trib.rb create --replicas $REPLICAS $HOSTS

  exit 0

  fi

  if [ "$1" == "stop" ]

  then

  while [ $((PORT  ENDPORT)) != "0" ]; do

  PORT=$((PORT+1))

  echo "Stopping $PORT"

  $BINDIR/redis-cli -p $PORT shutdown nosave

  done

  exit 0

  fi

  if [ "$1" == "watch" ]

  then

  PORT=$((PORT+1))

  while [ 1 ]; do

  clear

  date

  $BINDIR/redis-cli -p $PORT cluster nodes | head -30

  sleep 1

  done

  exit 0

  fi

  if [ "$1" == "tail" ]

  then

  INSTANCE=$2

  PORT=$((PORT+INSTANCE))

  tail -f ${PORT}.log

  exit 0

  fi

  if [ "$1" == "call" ]

  then

  while [ $((PORT  ENDPORT)) != "0" ]; do

  PORT=$((PORT+1))

  $BINDIR/redis-cli -p $PORT $2 $3 $4 $5 $6 $7 $8 $9

  done

  exit 0

  fi

  if [ "$1" == "clean" ]

  then

  cd $DATADIR

  rm -rf *.log

  rm -rf appendonly*.aof

  rm -rf dump*.rdb

  rm -rf nodes*.conf

  cd -

  exit 0

  fi

  echo "Usage: $0 [start|create|stop|watch|tail|clean]"

  echo "start -- Launch Redis Cluster instances."

  echo "create -- Create a cluster using redis-trib create."

  echo "stop -- Stop Redis Cluster instances."

  echo "watch -- Show CLUSTER NODES output (first 30 lines) of first node."

  echo "tail -- Run tail -f of instance at base port + ID."

  echo "clean -- Remove all instances data, logs, configs."123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960616263646566676869707172737475767778798081828384858687888990919293949596979899100101102123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960616263646566676869707172737475767778798081828384858687888990919293949596979899100101102

  不要忘了創(chuàng)建數(shù)據(jù)目錄mkdir -p /opt/redis/data

  根據(jù)上面的參考,啟動集群和停止集群

  啟動集群:先敲入/opt/redis/create-cluster start回車,再敲入/opt/redis/create-cluster create回車,再輸入yes回車

  停止集群:敲入/opt/redis/create-cluster stop回車

  如果以前啟動過,造成不一致數(shù)據(jù),create時就會報錯,可先/opt/redis/create-cluster clean

  測試

 

dependency>
 groupId>redis.clients/groupId>
 artifactId>jedis/artifactId>
 version>2.8.1/version>
/dependency>

  聲明JedisCluster Bean

@Bean
 public JedisCluster jedisCluster(){
  SetHostAndPort> nodes=new HashSet>(3);
  nodes.add(new HostAndPort("192.168.1.194",30001));
  nodes.add(new HostAndPort("192.168.1.194",30002));
  nodes.add(new HostAndPort("192.168.1.194",30003));
  return new JedisCluster(nodes,2000,5);
 }

  測試set和get

  

 AnnotationConfigApplicationContext context= new AnnotationConfigApplicationContext(AppConfig.class);
  JedisCluster jedisCluster = (JedisCluster) context.getBean("jedisCluster");
  jedisCluster.set("xxx","123");
  System.out.println("jedisCluster.get = " + jedisCluster.get("xxx"));

  安裝過程可能遇到的問題:

  make test時,提醒You need tcl 8.5 or newer in order to run the Redis test.到http://www.tcl.tk/software/tcltk/download.html下載Tcl,

 

wget http://prdownloads.sourceforge.net/tcl/tcl8.5.19-src.tar.gz
tar xf tcl8.5.19-src.tar.gz
cd tcl8.5.19/unix
./configure
make
make test
make install

  因為create-cluster create會調(diào)用redis-trib.rb,它是一個ruby腳本,所以提示沒有安裝ruby,就先安裝yum install -y ruby

  如果提示加載rubygems錯誤,使用以下辦法安裝rubygems

  a.https://rubygems.org/pages/download下載tgz格式的安裝包(wget可能不通,在windows用旋風或迅雷下載)

  b.mount -t cifs -o username=xiejx618,password=123456 //192.168.1.115/share /share

  

cp /share/rubygems-2.6.4.tgz ./
tar xf rubygems-2.6.4.tgz
cd rubygems-2.6.4
ruby setup.rb

  如果再提示no such file to load – rdoc/rdoc,就先安裝yum install -y rdoc

  如果再提示 no such file to load – redis,就使用gem install redis -v 3.0.7

  gem又是因為墻原因無法使用默認源,就修改為淘寶源

  可能用到的幾個命令

  幫助:gem sources --help

  查看源:gem sources -l

  刪除源:gem sources -r https://rubygems.org/

  添加源:gem sources -a https://ruby.taobao.org/

  更新源緩存:gem sources -u
