--------------------

## 一、环境准备 ##

Redis官网：[https://redis.io/][https_redis.io]

历史版本：[http://download.redis.io/releases/][http_download.redis.io_releases]

### 1、安装依赖 ###

yum -y install gcc gcc-c++ make cmake lrzsz

### 2、解压redis ###

tar zxvf redis-6.0.1.tar.gz

## 二、redis编译安装 ##

### 1、编译redis ###

cd redis-6.0.1 &&  make

redis6需要较高版本的gcc编译

如果make失败，需要手动升级gcc版本（redis5以下的不需要升级）

yum -y install centos-release-scl
    yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
    scl enable devtoolset-9 bash
    echo "source /opt/rh/devtoolset-9/enable" >> /etc/profile  ## gcc版本永久生效

### 2、安装redis ###

make install PREFIX=/usr/local/redis

### 3、拷贝redis.conf ###

mkdir /usr/local/redis/etc
    cp redis.conf /usr/local/redis/etc

### 4、启动redis ###

nohup /usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf  2>&1 &

## 三、redis环境配置 ##

### 1、配置环境变量 ###

## 在 /etc/profile 后添加
    REDIS_HOME=/usr/local/redis/
    PATH=$PATH:$REDIS_HOME/bin

### 2、开机自启配置 ###

## 在 /etc/rc.local 下添加
    echo never > /sys/kernel/mm/transparent_hugepage/enabled
    /usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf

### 3、其他配置 ###

# 注释掉绑定ip，允许远程连接
    bind 127.0.0.1 # 注释掉这句
    # 允许后台运行
    daemonize yes
    # 关闭保护模式，否则外部ip无法连接
    protected-mode no
    # 防火墙开启redis端口，默认6379
    firewall-cmd --add-port=6379/tcp --permanent
    firewall-cmd --reload
    firewall-cmd --list-ports
    # 内存设置
    echo 8192 > /proc/sys/net/core/somaxconn ## 最大内存8G
    sysctl vm.overcommit_memory=1  ## 内存超出时开辟内存 
    /etc/sysctl.conf 文件添加
    vm.overcommit_memory = 1
    # 密码设置 redis.conf 文件下添加
    requirepass 123456
    # 不重启设置密码（永久有效），登录之后输入
    config set requirepass 123456
    # 查询密码
    config get requirepass
    # 验证密码
    auth 123456
    # 登录时，验证登录输入一下
    auth 123456

### 4、redis关闭方法 ###

redis-cli shutdown
    ps -ef | grep redis | grep -v grep | awk '{print $2}' | xargs kill -9
    redis-cli -h 127.0.0.1 -p 6379 shutdown

## 四、redis系统服务 ##

### 1、redis添加到系统服务 ###

vi /lib/systemd/system/redis.service

[Unit]
    Description=The redis-server Process Manager
    Documentation=https://redis.io/
    After=network.target
     
    [Service]
    Type=forking
    ExecStart=/usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf
    ExecStop=/usr/local/redis/bin/redis-cli shutdown
     
    [Install]
    WantedBy=multi-user.target

### 2、redis系统服务命令 ###

systemctl enable redis
    systemctl start redis
    systemctl stop redis
    systemctl status redis

## 五、redis JavaAPI ##

### 1、Maven配置 ###

<dependency>
          <groupId>redis.clients</groupId>
          <artifactId>jedis</artifactId>
          <version>3.1.0</version>
        </dependency>

### 2、java连接 redis ###

import redis.clients.jedis.Jedis;
    
    Jedis jedis = new Jedis("localhost");
    jedis.auth("123456"); 
    jedis.set("mmsi", "123456789");
    //存储数据到列表中
     jedis.lpush("site-list", "Runoob");
     jedis.lpush("site-list", "Google");
     jedis.lpush("site-list", "Taobao");
    // 获取存储的数据并输出
    List<String> list = jedis.lrange("site-list", 0 ,2);
    for(int i=0; i<list.size(); i++) {
         System.out.println("列表项为: "+list.get(i));
    }
    // 获取数据并输出
    Set<String> keys = jedis.keys("*"); 
    Iterator<String> it=keys.iterator() ;   
    while(it.hasNext()){   
       String key = it.next();   
       System.out.println(key);   
    }

### 3、redis连接池 ###

package com.xtd.utils.redis;
    
    import redis.clients.jedis.Jedis;
    import redis.clients.jedis.JedisPool;
    import redis.clients.jedis.JedisPoolConfig;
    
    import java.util.Set;
    
    public class RedisUtil {
    
        private static JedisPool jedisPool;
    
        private String ip = "127.0.0.1";
    
        private Integer port;
        private Integer maxIdle;
        private Long maxWait;
    
        public RedisUtil(Integer port) {
            this.port = port;
            this.maxIdle = 10;
            this.maxWait = -1L;
            initJedisPool();
        }
    
        public RedisUtil(String ip, Integer port) {
            this.ip = ip;
            this.port = port;
            this.maxIdle = 10;
            this.maxWait = -1L;
            initJedisPool();
        }
    
        public RedisUtil(String ip, Integer port, Integer maxIdle, Long maxWait) {
            this.ip = ip;
            this.port = port;
            this.maxIdle = maxIdle;
            this.maxWait = maxWait;
            initJedisPool();
        }
    
        public Jedis getJedis() {
            return jedisPool.getResource();
        }
    
        private void initJedisPool() {
            JedisPoolConfig config = new JedisPoolConfig();
            config.setMaxIdle(maxIdle);
            config.setMaxWaitMillis(maxWait);
            config.setMaxTotal(10000);
            jedisPool = new JedisPool(config, ip, port, 60000);
        }
    
        public static void main(String[] args) {
    //        Jedis jedis = new RedisUtil("192.168.0.102", 6379).getJedis();
    //        Jedis jedis = new RedisUtil("127.0.0.1", 6379).getJedis();
            Jedis jedis = new RedisUtil(6379).getJedis();
            jedis.select(0);
            Set<String> set = jedis.keys("t_route_local-*");
            jedis.set("station_v1_01","station_v1_01;station,\\`date\\`,\\`time\\`,lat,long,visibility,air_temperature,wind_direction,wind_speed,air_pressure,precipitaion,sea_temperature,sea_salt,wave_period,wave_height;station_par,month_par");
            for (String s : set) {
    //            jedis.del(s);
                System.out.println(s);
            }
            String value =  jedis.get("station_v1_01");
            System.out.println(value);
            System.out.println(set.size());
            jedis.close();
        }
    
    
    }
