## 一。Redis的安装与使用（Linux） ##

**1.首先进入到我们需要安装redis的文件路径下，再根据我们的需要现在对应版本的redis压缩包，我的安装路径为/opt/software，下载的redis版本为5.0.0：**

> cd /opt/software  
> wget http://download.redis.io/releases/redis-5.0.0.tar.gz

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDAwOTQ0Nw_size_16_color_FFFFFF_t_70]  
**2.解压该压缩包：**

> tar -zxvf redis-5.0.0.tar.gz

![在这里插入图片描述][20200610215318637.png]  
**3.进入到解压缩后的文件夹，编译安装redis：**

> cd redis-5.0.0  
> make install

**4.安装完成后如下图所示：**

**5.进入src目录，启动redis：**

> cd src  
> redis-server

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDAwOTQ0Nw_size_16_color_FFFFFF_t_70 3]  
**6.复制一个会话，进入到刚刚redis-server所在的src目录下，启动redis-cli客户端，对redis进行操作：**

> cd /opt/software/redis-5.0.0/src  
> redis-cli

**7.至此redis基于默认配置启动以及使用就成功了！**

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

## 二。修改默认端口以及启动多个Redis ##

**1.进入到redis安装目录，找到redis-conf配置文件**

> cd /opt/software/redis-5.0.0  
> ll

**2.新建一个conf文件夹，复制redis-conf到conf文件夹中：**

> mkdir conf  
> cp redis.conf conf/

**3.首先我们得了解一下redis.conf配置文件中的主要属性：**

**4.修改配置主要如下：**

> port 6370  
> daemonize yes  
> logfile “6370.log”  
> dir /opt/software/redis-5.0.0/log

**5.在安装目录下新建一个log文件夹：**

> cd /opt/software/redis-5.0.0  
> mkdir log

**6.根据修改后的配置启动redis，控制台不打印日志信息，我们直接用命令查看：**

> redis-server conf/redis.conf  
> ps -ef | grep redis-

![在这里插入图片描述][202006102316447.png]  
**7.由上图所示，redis端口已经修改为6370。**

**8.进入日志文件夹，查看redis日志：**

**9.若需要启动多个redis，只需要在conf文件夹中复制多个redis.conf文件，修改conf文件中的端口，再修改conf的文件名称，启动redis-server时指定好启动的配置文件就行了。**
