redis 使用密码 redis设置密码登录

前言

redis在生产环境中通常都会设置密码以保证一定的安全性，本篇blog就简单记录一下如何在redis中设置客户端登录密码。

修改redis.conf

RT，打开redis.conf文件，搜索requirepass关键字，如下图： 

关注标记的那一行，#requirepass foobared。设置密码的方法就是去掉注释的#，把foobared替换成自己的密码即可，例如将密码设置为123456： 

修改完成后重启redis，再次通过redis客户端redis-cli登录并操作可以发现会报一个身份认证错误： 

这就说明我们已经成功的设置了密码，所以通过客户端连接的话必须加上密码参数才能正常连接： 

如上图所示，加了-a参数之后即可正常连接并操作redis。

jedis设置密码

当我们用Java客户端连接redis时会遇到同样的问题，下面看一段简单的jedis连接redis的测试代码：

<span style="color:#333333"><code><span style="color:#000088"><span style="color:#000088">package</span></span> com.firstelite.test;

<span style="color:#000088"><span style="color:#000088">import</span></span> org.junit.Test;

<span style="color:#000088"><span style="color:#000088">import</span></span> redis.clients.jedis.Jedis;

<span style="color:#000088"><span style="color:#000088">public</span></span> <span style="color:#000088"><span style="color:#000088">class</span></span> <span style="color:#660066"><span style="color:#660066">Test4Jedis</span></span> {

    <span style="color:#9b859d"><span style="color:#9b859d">@Test</span></span>
    <span style="color:#000088"><span style="color:#000088">public</span></span> <span style="color:#000088"><span style="color:#000088">void</span></span> <span style="color:#333333">testTwo</span>() {
        Jedis jedis = <span style="color:#000088"><span style="color:#000088">new</span></span> Jedis(<span style="color:#008800"><span style="color:#008800">"192.168.145.10"</span></span>);
        System.out.println(<span style="color:#008800"><span style="color:#008800">"Connection to server sucessfully"</span></span>);
        <span style="color:#880000"><span style="color:#880000">// 查看服务是否运行</span></span>
        System.out.println(<span style="color:#008800"><span style="color:#008800">"Server is running: "</span></span> + jedis.ping());
    }

}
</code></span>

非常简单，仅仅是测试一下Jedis是否连通redis服务器，运行junit后我们发现报异常了：

</code></span>

显而易见，由于我们设置了密码但在这里又没有指定密码，所以报了和刚才相同的错误，那么如何指定密码呢？很简单，Jedis的父类BinaryJedis提供了这样一样方法：

<span style="color:#333333"><code>  <span style="color:#000088"><span style="color:#000088">public</span></span> String <span style="color:#333333">auth</span>(<span style="color:#000088"><span style="color:#000088">final</span></span> String password) {
    checkIsInMulti();
    client.auth(password);
    <span style="color:#000088"><span style="color:#000088">return</span></span> client.getStatusCodeReply();
  }</code></span>

所以在创建了Jedis的实例后再加上一行jedis.auth("123456"); 即可，最后看一下运行结果： 

spring-data-redis设置密码

通常情况下在实际的java项目中我们会选择Spring提供的spring-data-redis来操作redis，spring的封装可以给我们提供很多便捷之处。那么spring-data-redis又是如何设置密码的呢？首先定义一个redis.properties配置文件，定义一组redis属性供spring加载使用，其中就包含密码（redis.password）：

<span style="color:#333333"><code><span style="color:#444444"><span style="color:#444444"># Redis settings  </span></span>
redis<span style="color:#444444">.host</span>=<span style="color:#006666"><span style="color:#006666">192.168</span>.145.10</span> 
redis<span style="color:#444444">.port</span>=<span style="color:#006666"><span style="color:#006666">6379</span></span>  
redis<span style="color:#444444">.password</span>=<span style="color:#006666"><span style="color:#006666">123456</span></span>
redis<span style="color:#444444">.timeout</span>=<span style="color:#006666"><span style="color:#006666">100000</span></span>  
redis<span style="color:#444444">.maxTotal</span>=<span style="color:#006666"><span style="color:#006666">300</span></span>  
redis<span style="color:#444444">.maxIdle</span>=<span style="color:#006666"><span style="color:#006666">100</span></span>  
redis<span style="color:#444444">.maxWaitMillis</span>=<span style="color:#006666"><span style="color:#006666">1000</span></span>  
redis<span style="color:#444444">.testOnBorrow</span>=<span style="color:#333333">true</span>  </code></span>

然后在由Spring封装的JedisConnectionFactory中来设置密码属性即可，下面是完整redis配置：
