## Redis下载 ##

官网下载稳定版本: www.redis.io  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQxNjA0ODkw_size_16_color_FFFFFF_t_70_pic_center]

## Linuk上安装Redis ##

解压Redis的安装包 程序一般放在 /opt 目录下
    	解压  redis tar -zxvf  redis-x.x.x.tar.gz
    	环境安装 
    	yum install gcc-c++  
    	# 然后进入redis目录下执行
    	make
    	make install
        安装出现问题：redis 6.0 以上 需要升级到gcc 9.3

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQxNjA0ODkw_size_16_color_FFFFFF_t_70_pic_center 1]

升级到gcc 9.3：
    yum -y install centos-release-scl
    yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
    scl enable devtoolset-9 bash
    需要注意的是scl命令启用只是临时的，退出shell或重启就会恢复原系统gcc版本。
    如果要长期使用gcc 9.3的话：
    echo "source /opt/rh/devtoolset-9/enable" >>/etc/profile

安装成功  
redis默认安装路径 /usr/local/bin

## 启动及设置redis ##

自建文件夹 mkdir xxxx
     在redis-x.x.x 目录下复制redis.conf到自建文件夹内  cp -r  redis.conf  /usr/local/bin/xxxx
    将redis.conf 拷贝 至 bin 目录下 自建文件夹内 方便修改启动
    启动redis 
    redis-server xxx/redis.conf

查看redis进程  
ps -ef | grep redis

idea连接服务器上的redis首先要在redis.conf改几个设置
    1.daemonize yes
    2.注释 bind 127.0.0.1(在Bind前面加个#号)
    3.protected-mode no
    4.在redis.conf 进行密码设置 
     搜索 # requirepass foobared
    requirepass xxxx     //注意，行前不能有空格
    auth password //重启redis 后验证密码
    注意: 看一下自己防火墙对端口号开没开放,部署远程服务器还要查看是否开放该端口
    firewall-cmd --query-port=6379/tcp
    如果是yes就是开放的
    是no的话就开启端口号:
    firewall-cmd --zone=public --add-port=6379/tcp --permanent

如果报出了FirewallD is not running的错误.  
解决方案:

1.  开启防火墙  
    systemctl start firewalld
2.  查看防火墙状态，显示running即开启成功  
    systemctl status firewalld
3.  再次执行需要的命令  
    firewall-cmd --zone=public --add-port=6379/tcp --permanent  
    firewall-cmd --reload

## springboot整合redis ##

### application.yml设置 ###

spring:
      redis:
          host: xx.xx.xx.xx 
          port: 6379
          timeout: 5000
          password: xxxxxx

### pom.xml引入redis依赖 ###

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-redis</artifactId>
    </dependency>

### windows 下载安装 redis ###

链接: [windows 版本下载地址][windows]

防火墙开放对应端口

#启动命令：cmd 执行
    redis-server.exe redis.windows.conf

注意命令中的“redis.windows.conf”是以.conf 为后缀的那个文件名，不要用“redis.windows-service.conf”

常见的问题是在启动Redis 时没有指定配置了密码的配置文件启动。
