Redis 設定密碼登入 轉
阿新 • • 發佈：2018-12-07
前言
redis在生產環境中通常都會設定密碼以保證一定的安全性，本篇blog就簡單記錄一下如何在redis中設定客戶端登入密碼。
修改redis.conf
RT，開啟redis.conf檔案，搜尋requirepass關鍵字，如下圖：
關注標記的那一行，#requirepass foobared。設定密碼的方法就是去掉註釋的#，把foobared替換成自己的密碼即可，例如將密碼設定為123456：
修改完成後重啟redis，再次通過redis客戶端redis-cli登入並操作可以發現會報一個身份認證錯誤：
這就說明我們已經成功的設定了密碼，所以通過客戶端連線的話必須加上密碼引數才能正常連線：
如上圖所示，加了-a引數之後即可正常連線並操作redis。
jedis設定密碼
當我們用Java客戶端連線redis時會遇到同樣的問題，下面看一段簡單的jedis連線redis的測試程式碼：
<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">// 檢視服務是否執行</span></span> System.out.println(<span style="color:#008800"><span style="color:#008800">"Server is running: "</span></span> + jedis.ping()); } } </code></span>

非常簡單，僅僅是測試一下Jedis是否連通redis伺服器，執行junit後我們發現報異常了：

顯而易見，由於我們設定了密碼但在這裡又沒有指定密碼，所以報了和剛才相同的錯誤，那麼如何指定密碼呢？很簡單，Jedis的父類BinaryJedis提供了這樣一樣方法：
<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>- 1

所以在建立了Jedis的例項後再加上一行jedis.auth("123456"); 即可，最後看一下執行結果：
spring-data-redis設定密碼
通常情況下在實際的java專案中我們會選擇Spring提供的spring-data-redis來操作redis，spring的封裝可以給我們提供很多便捷之處。那麼spring-data-redis又是如何設定密碼的呢？首先定義一個redis.properties配置檔案，定義一組redis屬性供spring載入使用，其中就包含密碼（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>

然後在由Spring封裝的JedisConnectionFactory中來設定密碼屬性即可，下面是完整redis配置：
