<p> </p>
<p><strong>二、解压</strong></p>
<div class="cnblogs_code">
<pre><span style="color: rgba(0, 0, 255, 1)">tar</span> -zxvf nginx-<span style="color: rgba(128, 0, 128, 1)">1.22</span>.<span style="color: rgba(128, 0, 128, 1)">1</span>.<span style="color: rgba(0, 0, 255, 1)">tar</span>.gz</pre>

<p> </p>
<p>三<strong>、安装所需环境</strong></p>
<p>#安装gcc</p>
<p>#官网下载的 nginx 源码进行编译，编译依赖 gcc 环境</p>
<div class="cnblogs_code">
<pre><span style="color: rgba(0, 0, 255, 1)">yum</span> <span style="color: rgba(0, 0, 255, 1)">install</span> <span style="color: rgba(0, 0, 255, 1)">gcc</span>-c++</pre>
</div>
<p><img src="https://img2022.cnblogs.com/blog/1968880/202211/1968880-20221114171413215-1133302174.png"></p>
<p> </p>
<p><strong>四、安装pcre pcre-devel</strong></p>
<p>#PCRE(Perl Compatible Regular Expressions) 是一个 Perl 库，包括 perl 兼容的正则表达式库。nginx 依赖 PCRE 库。</p>
<div class="cnblogs_code">
<pre><span style="color: rgba(0, 0, 255, 1)">yum</span> <span style="color: rgba(0, 0, 255, 1)">install</span> -y pcre pcre-devel</pre>
</div>
<p><img src="https://img2022.cnblogs.com/blog/1968880/202211/1968880-20221114172434419-1298009418.png"></p>
<p> </p>

<div class="cnblogs_code">
<pre><span style="color: rgba(0, 0, 255, 1)">yum</span> <span style="color: rgba(0, 0, 255, 1)">install</span> -y zlib zlib-devel</pre>
</div>
<p><img src="https://img2022.cnblogs.com/blog/1968880/202211/1968880-20221114172647270-163853936.png"></p>
<p> </p>
<p><strong>六、安装OpenSSL</strong></p>
<p>#OpenSSL 是一个开放源代码的软件库包，应用程序可以使用这个包来进行安全通信，避免窃听，同时确认另一端连接者的身份。这个包广泛被应用在互联网的网页服务器上。Nginx 也依赖 OpenSSL，需要在 Centos 安装此库。</p>
<div class="cnblogs_code">
<pre><span style="color: rgba(0, 0, 255, 1)">yum</span> <span style="color: rgba(0, 0, 255, 1)">install</span> -y openssl openssl-devel</pre>
</div>
<p><img src="https://img2022.cnblogs.com/blog/1968880/202211/1968880-20221114172859857-547934434.png"></p>
<p> </p>
<p><strong>七、配置Nginx</strong></p>
<div class="cnblogs_code">

<pre><span style="color: rgba(0, 0, 255, 1)">make</span>
<span style="color: rgba(0, 0, 255, 1)">make</span> <span style="color: rgba(0, 0, 255, 1)">install</span></pre>
</div>
<p> </p>
<p><strong>九、查找安装路径</strong></p>
<div class="cnblogs_code">
<pre><span style="color: rgba(0, 0, 255, 1)">whereis</span> nginx</pre>
</div>
<p><img src="https://img2022.cnblogs.com/blog/1968880/202211/1968880-20221114173936609-54771540.png"></p>

<p> #比如这里修改成9000</p>
<p><img src="https://img2022.cnblogs.com/blog/1968880/202211/1968880-20221114174953765-1177558978.png"></p>

firewall</span>-cmd --zone=public --list-ports</pre>
</div>
<p><img src="https://img2022.cnblogs.com/blog/1968880/202211/1968880-20221114175641789-1417528231.png"></p>
<p> </p>
<p><strong>十二、设置开机自启</strong></p>
<div class="cnblogs_code">
<pre>vi /lib/systemd/system/nginx.service</pre>
</div>
<p>#nginx.service内添加以下内容：</p>
<div class="cnblogs_code">
<pre>Description=nginx -<span style="color: rgba(0, 0, 0, 1)"> high performance web server
