<title>tcp相关配置</title></head><body><h4>linux 内核参数</h4>
<ul>
<li>tcp_max_syn_backlog: 用于设置半连接队列(syn queue，内核中实现为一个哈希表)大小</li>
<li>somaxconn: 用于设置全连接队列(accept queue)大小</li>
<li>syncookies: 开启此参数可以再不使用半连接队列的情况下成功建立连接</li>
</ul>
<h4>用户参数</h4>
<ul>
<li>backlog: 用于设置全连接队列大小</li>
</ul>
<p>tcp_max_syn_backlog， somaxconn， backlog这三个参数的最小值就是半连接队列的最大长度</p>
<p>somaxconn和backlog的最小值就是全连接队列的最大长度</p>
