在Centos部署nodejs的步骤
<p>今天突然发现自己买了一年快过期了的搬瓦工，除了少数时间拿来当梯子用用其它也没用上，所以流量还剩这么多。。。</p>
<p>
<img style="max-width:100%!important;height:auto!important;"title="在Centos部署nodejs的步骤" alt="在Centos部署nodejs的步骤" src="https://zhuji.jb51.net/uploads/img/202305/305f557f4a8c71751d34005fb1bf52c1.jpg"></p>
<p>
所以就想试试把本地写的nodejs的demo部署上去看看。</p>
<p>
顺便把原来买的域名解析上去QAQ</p>
<p>
<strong>安装node和npm</strong></p>
<p>
在官网下载编译好的node包:</p>

解压后得到 <code>node-v6.10.2-linux-x86 </code>文件夹，里面有个<code> bin </code>目录，包含了我们需要的 <code>node </code>和 <code>npm </code>。</p>
<p>
这里需要注意的是， <code>npm</code> 是链接到<code> ../lib/node_modules/npm/bin/npm-cli.js </code>的，不能直接拷贝到 <code>/usr/bin/ </code>,否则会出错，可以使用 ll 看到。</p>

输入<code> IP:8080 </code>就能看到 <code>Hello World! </code>了！</p>
<p>
<strong>域名绑定到ip</strong></p>
<p>
想起来原来有一个空闲的域名，正好试下域名绑定。</p>
<p>
在域名的 A 记录填写服务器的ip地址，等其生效即可。</p>
<p>
访问</p>
<p>
然后通过域名直接访问，发现并不能访问到我们的程序，因为默认访问的端口是 80 ，而我们监听的端口是 8080 。这里可以通过：</p>
<ol>
<li>
Nginx 反向代理</li>
<li>
iptables 端口转发</li>
</ol>
<p>
为了简单，直接用 iptables 端口转发了。。。</p>

这下可以愉快的通过域名访问刚刚部署的nodejs服务了。。。</p>

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持服务器之家。</p>
