• Redis3集群安装


    Redis3集群安装

    1. 什么是Redis

    Redis是目前一个非常优秀的key-value存储系统。和Memcached类似,它支持存储的value类型相对更多,包括string(字符串)list(链表)set(集合)zset(sorted set有序集合)hash(哈希类型)。

    2. 为什么要安装Redis3集群

    Redis3.x支持集群模式,更加可靠!

    3. 安装Redis3集群(6Linux

    参考文章:http://blog.csdn.net/myrainblues/article/details/25881535

    1.下载redis3的稳定版本,下载地址http://download.redis.io/releases/redis-3.2.10.tar.gz

    2.上传redis-3.2.10.tar.gz到服务器

    3.解压redis源码包

    tar -zxvf redis-3.2.10.tar.gz -C /usr/local/src/

    4.进入到源码包中,编译并安装redis

    cd /usr/local/src/redis-3.2.10/

    make && make install

    5.报错,缺少依赖的包

     

    6.配置本地YUM源并安装redis依赖的rpm

    yum -y install gcc

    7.编译并安装

    make && make install

    8.报错,原因是没有安装jemalloc内存分配器,可以安装jemalloc或直接输入

     

    9.重新编译安装

    make MALLOC=libc && make install

    10.用同样的方式在其他的机器上编译安装redis

    11.在所有机器的/usr/local/下创建一个redis目录,然后拷贝redis自带的配置文件redis.conf/usr/local/redis

    mkdir /usr/local/redis

    cp /usr/local/src/redis-3.2.10/redis.conf /usr/local/redis

    12.修改所有机器的配置文件redis.conf

    daemonize yes  #redis后台运行

    cluster-enabled yes  #开启集群把注释去掉

    appendonly yes  #开启aof日志,它会每次写操作都记录一条日志

    sed -i 's/daemonize no/daemonize yes/' /usr/local/redis/redis.conf

    sed -i "s/bind 127.0.0.1/ bind $HOST/" /usr/local/redis/redis.conf

    sed -i 's/# cluster-enabled yes/cluster-enabled yes/' /usr/local/redis/redis.conf

    sed -i 's/appendonly no/appendonly yes/' /usr/local/redis/redis.conf

    sed -i 's/# cluster-node-timeout 15000/cluster-node-timeout 5000/' /usr/local/redis/redis.conf

    13.启动所有的redis节点

    cd /usr/local/redis

    redis-server redis.conf

    14.查看redis进程状态

    ps -ef | grep redis

     

    15.(只要在一台机器上安装即可)配置集群:安装rubyruby gem工具(redis3集群配置需要rubygem工具,类似yum

    yum -y install ruby rubygems

    16.使用gem下载redis集群的配置脚本

    gem install redis

    ruby --version

    17.安装RVM

    curl -sSL https://rvm.io/mpapis.asc | gpg2 --import -

    curl -L get.rvm.io | bash -s stable

    source /usr/local/rvm/scripts/rvm

    rvm list known

    rvm install 2.3.4

    #ruby的工具安装reids

    gem install redis

    18.使用脚本配置redis集群

    cd /usr/local/src/redis-3.2.10/src/

    #service iptables stop

    #在第一机器上执行下面的命令

    ./redis-trib.rb create --replicas 1 192.168.10.101:6379 192.168.10.102:6379 192.168.10.103:6379 192.168.10.104:6379 192.168.10.105:6379 192.168.10.106:6379

    19.测试(别忘加-c参数)

    redis-cli -c -h 192.168.1.13

    4. Redis3伪分布式安装(1Linux

    1.下载redis3的稳定版本,下载地址http://download.redis.io/releases/redis-3.2.10.tar.gz

    2.上传redis-3.2.10.tar.gz到服务器

    3.解压redis源码包

    tar -zxvf redis-3.2.10.tar.gz -C /usr/local/src/

    4.进入到源码包中,编译并安装redis

    cd /usr/local/src/redis-3.2.10/

    make && make install

    5./usr/local/下创建一个redis目录,然后分别在/usr/local/redis目录创建6个文件夹7000,7001,7002,7003,7004,7005然后拷贝redis自带的配置文件redis.conf到这六个目录中

    mkdir /usr/local/redis

    mkdir /usr/local/redis/{7000,7001,7002,7003,7004,7005}

    cp /usr/local/src/redis-3.2.10/redis.conf /usr/local/redis/7000

    cp /usr/local/src/redis-3.2.10/redis.conf /usr/local/redis/7001

    cp /usr/local/src/redis-3.2.10/redis.conf /usr/local/redis/7002

    cp /usr/local/src/redis-3.2.10/redis.conf /usr/local/redis/7003

    cp /usr/local/src/redis-3.2.10/redis.conf /usr/local/redis/7004

    cp /usr/local/src/redis-3.2.10/redis.conf /usr/local/redis/7005

    6.分别修改这六个目录中的配置文件

    port 7000 #端口要与其所在的文件名一致

    pidfile /var/run/redis-7000.pid  #pid要与其所在的文件名一致

    daemonize yes

    cluster-enabled yes

    appendonly yes

    7.分别进入到这六个目录启动redis进程

    cd /usr/local/redis/7000

    redis-server redis.conf

    cd /usr/local/redis/7001

    redis-server redis.conf

    cd /usr/local/redis/7002

    redis-server redis.conf

    cd /usr/local/redis/7003

    redis-server redis.conf

    cd /usr/local/redis/7004

    redis-server redis.conf

    cd /usr/local/redis/7005

    redis-server redis.conf

    HOST=`ifconfig eth1 | grep "inet addr" | awk -F : '{print $2}' | awk '{print $1}'`

    sed -i "s/bind 127.0.0.1/bind $HOST/" /usr/local/redis/redis.conf

    分别进入几个redis的客户端中设置redis密码

    config set masterauth username
    
    config set requirepass passwd
    
    auth username
    
    config rewrite

    连接到创建的集群中(-c:参数一定要添加)

     /usr/local/src/redis-3.2.10/src/redis-cli -p 7005 -c

    停止redis服务

    redis-cli -h 192.168.100.101 -a 密码 shutdown

    创建集群的命令(初始化执行一次,以后只需要将redis启动就可以了)

    /usr/local/src/redis-3.2.10/src/redis-trib.rb  start --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

    查看集群运行状态命令

    /usr/local/src/redis-3.2.10/src/redis-trib.rb check 127.0.0.1:7001

    运行状态截图

     批量启动集群中机器

     1 #!/bin/bash
     2 
     3 echo "start redis on port 7000~7005"
     4 for i in {7000..7005}
     5 do 
     6     echo "[$i start now]"
     7     cd /usr/local/redis/$i
     8     /usr/local/src/redis-3.2.10/src/redis-server redis.conf
     9     sleep 1
    10 done
    11 
    12 for i in {7000..7005}
    13 do 
    14     REDIS_ID=$( ps -ef | grep redis | grep $i | grep -v 'grep' | head -1 | awk '{print $2}' )
    15     sleep 1
    16     if [ -z "$REDIS_ID" ]; then
    17         echo "port [$i] pid [$REDIS_ID] not start"
    18     else
    19         echo "port [$i] pid [$REDIS_ID] been start"
    20     fi
    21 done
    22 echo "start success redis port 7000~7005"
    stat-all.sh

    批量停止集群机器

     1 #!/bin/bash
     2 
     3 for i in {7000..7005}
     4 do 
     5     REDIS_ID=$( ps -ef | grep redis | grep $i | grep -v 'grep' | head -1 | awk '{print $2}' )
     6     if [ -z "$REDIS_ID" ]; then
     7         echo "[$REDIS_ID]... "
     8         echo "port [$i] pid [$REDIS_ID] has been stop"
     9     else
    10         echo "port [$i] pid [$REDIS_ID] will stop"
    11         kill -9 $REDIS_ID
    12         sleep 2
    13     fi
    14 done
    stop-all.sh
