Centos7 vmware安装rediscluster

本是古典何须时尚 2022-07-14 02:17 238阅读 0赞

系统环境: Centos7 vmware  
redis版本：redis3.2.5  
redis3.2.5需要高版本的ruby和gem，我这边ruby用的最新版本2.3.3,低版本的ruby创建集群的时候会出错  
安装步骤：

**一、所需工具初始化**

**1、安装开发包**

#yum install openssl* openssl-devel zlib-devel gcc gcc-c++ make autoconf readline-devel curl-devel expat-devel gettext-devel

openssl、zlib、gcc在安装ruby和gem的时候需要，后面的可以不需要  
**2、安装ruby**

# wget https://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.3.3.tar.gz
    # tar zxvf ruby-2.3.3.tar.gz
    # cd ruby-2.3.3
    # ./configure
    # make && make install
    # ruby -v

**3、安装redis-gem**

# wget https://rubygems.global.ssl.fastly.net/gems/redis-3.2.1.gem
    # gem install redis-3.2.1.gem

**二、rediscluster构建**  
**1、redis下载安装**

# wget http://download.redis.io/releases/redis-3.2.5.tar.gz 
    # tar -zxf redis-3.2.5.tar.gz
    # cd redis-3.2.5
    # make && make install

**2、集群配置**  
创建6个redis.conf文件（cluster最少需要6个节点）

# mkdir conf
    # cd conf
    # vi redis-6379.conf
    
    port 6379
    daemonize yes
    dir /data/redis/redis-6379
    logfile /data/redis/redis-6379/redis-6379.log
    pidfile /var/run/redis-6379.pid 
    dbfilename dump-6379.rdb  
    
    appendonly yes  
    appendfilename "appendonly-6379.aof" 
    
    cluster-enabled yes   
    cluster-config-file nodes-6379.conf  
    cluster-node-timeout 5000    
    
    protected-mode no#关闭保护模式
    
    maxmemory 1073741824#最大内存 
    maxmemory-policy volatile-lru#内存不足时,数据清除策略
    
    # cp redis-6379.conf redis-6380.conf && sed -i "s/6379/6380/g" redis-6380.conf 
    # cp redis-6379.conf redis-6381.conf && sed -i "s/6379/6381/g" redis-6381.conf
    # cp redis-6379.conf redis-6382.conf && sed -i "s/6379/6382/g" redis-6382.conf
    # cp redis-6379.conf redis-6383.conf && sed -i "s/6379/6383/g" redis-6383.conf
    # cp redis-6379.conf redis-6384.conf && sed -i "s/6379/6384/g" redis-6384.conf

说明：protected-mode 功能参考如下链接

*3、启动服务\**

# ./src/redis-server conf/redis-6379.conf
    # ./src/redis-server conf/redis-6380.conf
    # ./src/redis-server conf/redis-6381.conf
    # ./src/redis-server conf/redis-6382.conf
    # ./src/redis-server conf/redis-6383.conf
    # ./src/redis-server conf/redis-6384.conf

4、创建集群  
使用第二个（IP）创建，用127.0.0.1创建的jediscluster外部网络连接不上;  
–replicas 1的意思是每个master有1个slave

# ./src/redis-trib.rb create --replicas 1 127.0.0.1:6379 127.0.0.1:6380 127.0.0.1:6381 127.0.0.1:6382 127.0.0.1:6383 127.0.0.1:6384
    
    # ./src/redis-trib.rb create --replicas 1 172.21.20.25:6379 172.21.20.25:6380 172.21.20.25:6381 172.21.20.25:6382 172.21.20.25:6383 172.21.20.25:6384

![集群创建成功][20161124005811786]  
5、集群检测

#./src/redis-trib.rb check 172.21.20.10:6379

**三、客户端链接**  
客户端采用的jediscluster，采用的spring boot  
1、maven jar

<dependency>
        <groupId>redis.clients</groupId>
        <artifactId>jedis</artifactId>
        <version>2.9.0</version>
    </dependency>

2、bean注入

package com.hive.data.redis.config;
    
    import org.apache.commons.pool2.impl.GenericObjectPoolConfig;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.context.properties.EnableConfigurationProperties;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import redis.clients.jedis.HostAndPort;
    import redis.clients.jedis.JedisCluster;
    
    import java.util.HashSet;
    import java.util.List;
    import java.util.Set;
    
    @Configuration
    @EnableConfigurationProperties(RedisSettings.class)
    public class JedisClusterConfig {
        @Autowired
        private RedisSettings redisSettings;
        @Bean
        public JedisCluster jedisCluster() {
            Set<HostAndPort> set = new HashSet<HostAndPort>();
            List<String> hostPorts = redisSettings.getNodes();
            if (null != hostPorts && hostPorts.size() > 0) {
                String[] ipPortPair;
                for (String hostPort : hostPorts) {
                    ipPortPair = hostPort.split(":");
                    set.add(new HostAndPort(ipPortPair[0], Integer.parseInt(ipPortPair[1])));
                }
            }
            return new JedisCluster(set,300000);
        }
        @Bean
        public GenericObjectPoolConfig genericObjectPoolConfig(){
            GenericObjectPoolConfig config=new GenericObjectPoolConfig();
            config.setMaxTotal(500);
            config.setMaxIdle(5);
            config.setMaxWaitMillis(1000*100);
            config.setTestOnBorrow(true);
            return config;
        }
    }
    
    
    package com.hive.data.redis.config;
    
    import org.springframework.boot.context.properties.ConfigurationProperties;
    
    import java.util.List;
    @ConfigurationProperties(locations = "classpath:redis.properties",prefix = "redis.cluster")
    public class RedisSettings {
    
        private List<String> nodes;
    
    
        public List<String> getNodes() {
            return nodes;
        }
    
        public void setNodes(List<String> nodes) {
            this.nodes = nodes;
        }
    }
    
    redis.properties
    
    redis.cluster.nodes[0] =172.21.20.25:6379
    redis.cluster.nodes[1] =172.21.20.25:6380
    redis.cluster.nodes[2] =172.21.20.25:6381
    redis.cluster.nodes[3] =172.21.20.25:6382
    redis.cluster.nodes[4] =172.21.20.25:6383
    redis.cluster.nodes[5] =172.21.20.25:6384

四、防火墙关闭

我的虚拟机是centos7的默认防火墙，7以下默认是iptables的。

systemctl stop firewalld.service #停止firewall
    systemctl disable firewalld.service #禁止firewall开机启动

iptables设置方法  
重启后永久性生效：  
开启：chkconfig iptables on  
关闭：chkconfig iptables off  
即时生效，重启后失效：  
开启：service iptables start

关闭：  
service iptables stop  
重启：service iptables restart  
保存配置：service iptables save  
或者/etc/rc.d/init.d/iptables save  
设置防火墙开机启动  
systemctl enable iptables.service  
禁止防火墙在系统启动时启动  
/sbin/chkconfig –level 2345 iptables off
