<h3 id="utf8-编码问题"><a href="#utf8-编码问题" class="headerlink" title="utf8 编码问题"></a>utf8 编码问题</h3><p>这个问题，原因是UTF-8编码有可能是两个、三个、四个字节。Emoji表情或者某些特殊字符是4个字节，而Mysql的utf8编码最多3个字节，所以数据插不进去。 修改成utf8mb4 <a href="https://blog.csdn.net/fhzaitian/article/details/53168551" target="_blank" rel="noopener">https://blog.csdn.net/fhzaitian/article/details/53168551</a></p>

<h3 id="freeing-items"><a href="#freeing-items" class="headerlink" title="freeing items"></a>freeing items</h3><p>查询缓存命中率低，报错freeing items<br>实例：今天公司DB 有大量的线程是freeingitems 状态，通过排查分析是: query_cache_size=32M,而query_cache_limit=16M，太坑人了，DB游戏服务器上跑应用，还有一些大的不固定的数据抓取查询(不固定，经常变动)，结果使用了Query cache ，导致Query Cache 池的抖动，频繁有cache失效，产生了freeing items 状态,下面是官方对freeing items的解释：</p>
<p>The thread has executed acommand. Some freeing of items done during this state involves the query cache.This state is usually followed by cleaning up.</p>
<p>线程已经执行了命令。在这个状态中涉及的查询缓存可以得到一些释放。这个状态通常后面跟随cleaning up状态。</p>
<p>最后把query_cache_limit改成1M，很少有freeing items 状态。uery_cache_limit和query_cache_size的设置要紧结合具体的业务现状来调整。</p>

<pre><code>我们要怎么确定读取位置？1. 可以通过show slave status\G;输出中的Relay_Master_Log_File，Exec_Master_Log_Pos来确定；2. 如果show slave status\G;中的值你搞不清楚，也可以通过从库errorlog中的 报错来确定位置。</code></pre> <figure class="highlight plain"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br></pre></td><td class="code"><pre><span class="line"> >stop slave;</span><br><span class="line"> >reset slave;</span><br><span class="line"> >change master to master_host='15.12.52.17', master_user='rexxxungbinpl', master_password='rFfs2', master_port=3306, master_log_file='mysql-bin.002512', master_log_pos=159596385;</span><br></pre></td></tr></table></figure>
