阿里云环境迁移记录 - Redis集群搭建

﹏ヽ暗。殇╰゛Y 2022-01-17 09:07 219阅读 0赞

Redis集群需要至少6个节点，3主3从，由于服务器资源有些，这里使用3台机器6个端口实现。

\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#

1.  yum install gcc
2.  tcl安装
    
        wget http://downloads.sourceforge.net/tcl/tcl8.6.1-src.tar.gz
        rsync -e 'ssh -p 20462' tcl8.6.1-src.tar.gz root@172.26.27.72:/opt/install/
        rsync -e 'ssh -p 20462' tcl8.6.1-src.tar.gz root@172.26.27.72:/opt/install/
        sudo tar xzvf tcl8.6.1-src.tar.gz -C /usr/local/
        cd /usr/local/tcl8.6.1/unix/
        ./configure
        make && make install
3.  ruby安装
    
        wget http://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.3.5.tar.gz
        rsync -e 'ssh -p 20462' ruby-2.3.5.tar.gz root@172.26.27.71:/opt/install/
        rsync -e 'ssh -p 20462' ruby-2.3.5.tar.gz root@172.26.27.72:/opt/install/
        tar -xvf ruby-2.3.5.tar.gz
        cd ruby-2.3.5
        ./configure  --prefix=/opt/ruby
        make && make install
        ln -s /opt/ruby/bin/ruby /usr/bin/ruby
        ln -s /opt/ruby/bin/gem /usr/bin/gem
4.  rubygem安装
    
        wget http://rubygems.org/downloads/redis-4.0.1.gem
        rsync -e 'ssh -p 20462' redis-4.0.1.gem root@172.26.27.71:/opt/install/
        rsync -e 'ssh -p 20462' redis-4.0.1.gem root@172.26.27.72:/opt/install/
        gem install -l redis-4.0.1.gem
5.  yum -y install zlib-devel
    
        进入ruby源码文件夹,安装ruby自身提供的zlib包
        cd ruby-2.3.5/ext/zlib
        ruby ./extconf.rb
        make
        make install

wget http://download.redis.io/releases/redis-4.0.0.tar.gz
    tar xzf redis-4.0.0.tar.gz
    cd redis-4.0.0
    #make（make MALLOC=libc）
    cd src/        
    make test 
    make install

# Part3 redis集群搭建 #

\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#  
redis集群的最小单元是3主3从，即6个节点，这里我们用三台物理机，6个端口实现，  
三主:6239  
三从:6339  
host1: 172.26.27.72  
host2: 172.26.27.71  
host1: 172.26.27.70

分别在3台机器上创建端口目录:

mkdir -p /data/redis-cluster/logs
    mkdir -p /data/redis-cluster/{6239,6339}
    mkdir -p /data/redis-cluster/{6239,6339}
    mkdir -p /data/redis-cluster/{6239,6339}

copy配置文件并修改

cp /opt/install/redis-4.0.0/redis.conf /data/redis-cluster/6239/node_6239.conf
    cp /opt/install/redis-4.0.0/redis.conf /data/redis-cluster/6339/node_6339.conf

vim node\_6239.conf

bind 172.26.27.72 47.92.238.93 127.0.0.1
    port 6239
    daemonize yes
    pidfile /var/run/redis_6239.pid
    logfile "/data/redis-cluster/logs/6239.log"
    dir /data/redis-cluster/6239/
    cluster-enabled yes
    cluster-config-file  cluster-node-6239.conf
    cluster-node-timeout 15000
    masterauth 88gongxiangrds
    requirepass 88gongxiangrds

vim node\_6339.conf

bind 172.26.27.72 47.92.238.93 127.0.0.1
    port 6339
    daemonize yes
    pidfile /var/run/redis_6339.pid
    logfile "/data/redis-cluster/logs/6339.log"
    dir /data/redis-cluster/6339/
    cluster-enabled yes
    cluster-config-file cluster-node-6339.conf
    cluster-node-timeout 15000
    masterauth 88gongxiangrds
    requirepass 88gongxiangrds

\#vim编辑替换  
`:%s/6239/6339/g`

\#启动3台服务器上的6个redis节点，创建集群，每个节点一个副本

redis-server /data/redis-cluster/6239/node_6239.conf
    redis-server /data/redis-cluster/6339/node_6339.conf

cd /opt/install/redis-4.0.0
    ./redis-4.0.0/src/redis-trib.rb create  --replicas 1 172.26.27.72:6239  172.26.27.72:6339 172.26.27.71:6239  172.26.27.71:6339 172.26.27.70:6239  172.26.27.70:6339

\#\#检查集群完整性

cd /opt/install/redis-4.0.0
    ./src/redis-trib.rb check 172.26.27.72:6339

\#\#登录查看集群状态

redis-cli -h 172.26.27.72 -p 6239 -a 88gongxiangrds
    > cluster info

\#\#redis重启  
//停止某个节点服务

redis-cli  -h 172.26.27.71 -p 6239 -a 88gongxiangrds shutdown 
    redis-cli  -h 172.26.27.70 -p 6339 -a 88gongxiangrds shutdown

//启动某个节点服务

redis-server /data/redis-cluster/6239/node_6239.conf 
    redis-server /data/redis-cluster/6339/node_6339.conf

\#\#\#动态修改密码写入文件

redis-cli -h 172.26.27.70 -p 6239 -c
    config set masterauth xxx
    config set requirepass xxx
    config rewrite

\#\#\#spring boot整合配置

spring.redis.database=0
    spring.redis.cluster.nodes=172.26.27.72:6239,172.26.27.72:6339,172.26.27.71:6239,172.26.27.71:6339,172.26.27.70:6239,172.26.27.70:6339
    spring.redis.password=88gongxiangrds
    spring.redis.pool.max-active=8  
    spring.redis.pool.max-wait=-1  
    spring.redis.pool.max-idle=8  
    spring.redis.pool.min-idle=0  
    spring.redis.timeout=0
