# linux下redis安装 #

> [redis中文文档地址][redis]

> [redis 5.0.2集群搭建][redis 5.0.2]

*  ### **前置条件:由于redis是由C语言编写的，它的运行需要C环境，因此我们需要先安装gcc。** ###
    
    > linux安装gcc，命令：**yum install gcc-c++**，根据提示输入y确认即可
 *  ### 下载地址 ###
    
    1.  [redis官网][redis 1]
    2.  [redis多版本地址][redis 2]
    3.  4.0.14版本地址( http://download.redis.io/releases/redis-4.0.14.tar.gz )
 *  ### 安装 ###
    
    1.  **下载： wget http://download.redis.io/releases/redis-4.0.14.tar.gz**

        > cd redis-4.0.14  
        > make  
        > ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1MjE1ODIx_size_16_color_FFFFFF_t_70]
    4.  **进入src目录后安装**
        
        > **cd src/**  
        > **make install**

    1.  **vim redis.conf**  
        ![在这里插入图片描述][20190917212923482.png]
    2.  **搜索daemonize属性改为yes表示需要后台执行（修改为yes）**

    4.  **搜索protected-mode 取消阻止远程访问（修改为no才可以远程连接）**  
        ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1MjE1ODIx_size_16_color_FFFFFF_t_70 3]
    5.  **搜索requirepass foobared添加默认密码(默认为空，不设置密码可忽略)**  
        ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1MjE1ODIx_size_16_color_FFFFFF_t_70 4]
    6.  **:wq 保存**
 *  ### 启动 ###
    
    1.  **设置开机启动**
        
        > **vi /etc/rc.d/rc.local**  
        > 添加redis-server redis.conf的绝对路径  
        > ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1MjE1ODIx_size_16_color_FFFFFF_t_70 5]
    2.  **手动启动（指定redis-server redis.conf）**
        
        > ###### **./redis-4.0.14/src/redis-server ./redis-4.0.14/redis.conf**![在这里插入图片描述][2019091721455731.png] ######
 *  ### 连接redis ###
    
    1.  **本地连接（-h 地址，-p 端口，-a 密码）**
        
        > ./redis-4.0.14/src/redis-cli -h 127.0.0.1 -p 6379 -a 123456  
        > ![在这里插入图片描述][20190917215844442.png]
    2.  **远程连接出现问题，检查linux防火墙是否开放该端口**  
        ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1MjE1ODIx_size_16_color_FFFFFF_t_70 6]
    3.  **检查防火墙是否开放6379端口(root权限)**
        
        > **/etc/init.d/iptables status**  
        > ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1MjE1ODIx_size_16_color_FFFFFF_t_70 7]
    4.  **防火墙添加6379端口**
        
        > vim /etc/sysconfig/iptables  
        > 复制22端口那行然后再改一下端口即可  
        > ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1MjE1ODIx_size_16_color_FFFFFF_t_70 8]
    5.  **启动防火墙服务**
        
        > service iptables restart  
        > ![在这里插入图片描述][20190917221053931.png]
    6.  **再次连接**  
        ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1MjE1ODIx_size_16_color_FFFFFF_t_70 9]
 *  ### **监控redis** ###
    
    1.  **–stat参数**
        
        > **keys**表示redis所有key的个数  
        > **mem**表示redis占用的内存  
        > **clients**表示客户端连接的数量  
        > **blocked**表示已阻止的客户端数  
        > **requests**表示正在执行的命令数(QPS)  
        > **connections**表示当前连接总数。  
        > ![在这里插入图片描述][20190917222747951.png]
    2.  **monitor参数用于实时监控redis请求命令**
        
        > 也可以用 ./redis-cli -a 123456 monitor | grep -v “PING” 过滤不想看的命令  
        > ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1MjE1ODIx_size_16_color_FFFFFF_t_70 10]
    3.  **cluster nodes参数查看redis集群信息**
