CentOS7.2安装Nginx的方法步骤
<p>CentOS7.2安装Nginx过程笔记，由于学习的需要，这段时间学一点“nginx”。今天学习一下Nginx安装，留个笔记</p>
<p>
<strong>查看CentOS的版本</strong></p>
<p>
使用一下命令来查看一下当前系统的版本</p>

<strong>添加资源库</strong></p>
<p>
在 CentOS 系统上安装 Nginx ，你得先去添加一个资源库，像这样：</p>

<div class="toolbar">

</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">

<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain">vim </code><code class="bash plain">/etc/yum</code><code class="bash plain">.repos.d</code><code class="bash plain">/nginx</code><code class="bash plain">.repo</code>
</div>
</div>
</td>

</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
使用 vim 命令去打开 /etc/yum.repos.d/nginx.repo ，如果 nginx.repo 不存在，就会去创建一个这样的文件，打开以后按一下小 i 键，进入编辑模式，然后复制粘贴下面这几行代码，完成以后按 esc 键退出，再输入:wq （保存并退出）</p>

<strong>测试nginx配置文件</strong></p>

当你执行 nginx -t 得时候，nginx会去测试你得配置文件得语法，并告诉你配置文件是否写得正确，同时也告诉了你配置文件得路径：</p>

<strong>centos7.0+ nginx实现停止、启动、重启</strong></p>
<p>
在CentOS7中，进行chkconfig命令操作时会发现有类似“systemctl.....”的提示，systemctl可以简单实现service和chkconfig的结合，这样通过一个命令就可以实现两个命令的功能。</p>
<p>
systemctl命令的基本操作格式是：</p>
