<p><strong>來到C:\Windows\System32目錄下 找到cmd.exe 右鍵以管理員身份執行（一定要這樣哦！）</strong></p>

<p><strong>說明mysql服務還在 把它刪掉 </strong></p>
<p><strong>用這個命令</strong></p>
<p><strong>sc delete mysql</strong></p>

<p><strong>好了 可以把cmd視窗關了 ！用不到它了。</strong></p>
<p><strong>相信大家都有Navicat 、小海豚等資料庫圖形化工具</strong></p>
<blockquote> <p>我也分享一個免安裝的Navicat Premium 12</p>
<p>連結：https://pan.baidu.com/s/1TrPYBOU8APWlarFW_QTLlQ 密碼：7jbs</p> </blockquote>
<p><strong>我們的mysql服務已經開啟了 就直接開啟Navicat去連線</strong></p>
<p><img alt="" class="has" src="https://img-blog.csdn.net/20180815175637715?watermark/2/text/aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3MzUwNzA2/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70"></p>
<p><strong>新建mysql連線</strong></p>

<p><strong>還記得剛剛讓你複製的[email protected]:後面的初始密碼了嗎？ 現在要用到它了 複製貼上上去！</strong></p>
<p><strong>測試一下 ！</strong></p>
<p><img alt="" class="has" src="https://img-blog.csdn.net/20180815175404692?watermark/2/text/aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3MzUwNzA2/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70"></p>
<p><strong>mysql是成功安裝了 也可以登入 </strong></p>
<p><strong>現在就是改密碼的時候了</strong></p>
<p><strong>寫sql改密碼嗎？</strong></p>
<p><strong>太麻煩了 太low</strong></p>
<p><strong>來 我有個簡單的方法</strong></p>
<p><strong>用Navicat 點選剛剛的連線 </strong></p>
<p><strong>就會提示我們輸入新密碼</strong></p>
