CentOS 7 安装 fping
<h2>CentOS 7.6.1810 安装 fping 3.15</h2><p>1、创建安装目录</p>
<div class="cnblogs_code">
<pre><span style="color: rgba(0, 0, 255, 1)">mkdir</span> -p /usr/local/fping && cd /usr/local/fping</pre>
</div>
<p>2、下载 fping3.15 安装包</p>
<div class="cnblogs_code">
<pre><span style="color: rgba(0, 0, 255, 1)">wget</span> http:<span style="color: rgba(0, 128, 0, 1)">//</span><span style="color: rgba(0, 128, 0, 1)">fping.org/dist/fping-3.15.tar.gz</span></pre>
</div>
<p>3、解压安装包</p>
<div class="cnblogs_code">
<pre><span style="color: rgba(0, 0, 255, 1)">tar</span> -zxvf fping-<span style="color: rgba(128, 0, 128, 1)">3.15</span>.<span style="color: rgba(0, 0, 255, 1)">tar</span>.gz && cd fping-<span style="color: rgba(128, 0, 128, 1)">3.15</span></pre>
</div>
<p>4、编译安装</p>
<div class="cnblogs_code">
<pre>./configure --prefix=/usr/local/fping && <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>5、配置环境变量，并使其生效</p>
<div class="cnblogs_code">
<pre><span style="color: rgba(0, 0, 255, 1)">sed</span> -i <span style="color: rgba(128, 0, 0, 1)">'</span><span style="color: rgba(128, 0, 0, 1)">1i\export PATH=$PATH:/usr/local/fping/sbin</span><span style="color: rgba(128, 0, 0, 1)">'</span> /etc/profile && source /etc/profile</pre>
</div>
<p>6、配置环境变量永久生效</p>
<div class="cnblogs_code">
<pre><span style="color: rgba(0, 0, 255, 1)">echo</span> <span style="color: rgba(128, 0, 0, 1)">"</span><span style="color: rgba(128, 0, 0, 1)">export PATH=$PATH:/usr/local/fping/sbin</span><span style="color: rgba(128, 0, 0, 1)">"</span> >> /etc/bashrc</pre>
</div>
<p>7、测试成功与否？</p>
<div class="cnblogs_code">
<pre>fping -v</pre>
</div>
<p> </p>

<p>-a 显示目标地址是否在线<br> -A 以IP地址显示，并判断是否在线<br> -b n 发送ping的数据包量,以字节为单位 (默认 56)，n写成数量，以下参数同此<br> -B f 设置指数回退因素为f<br> -c n 计算要发送到每个目标的ping信号 (默认发送 1 个包)<br> -C n 功能同-c，报告结果更详细<br> -D 在每个输出行打印时间戳<br> -e 显示返回包的运行时间<br> -f file 从文件中读取目标列表 ( - means stdin) (only if no -g specified)</p>

运动可以增加体力；读书可以增加知识；
自古只有天才的学生，没有天才的老师；
猴子不上树是看不见红屁股的，
人不做事情是看不出能力的。
时间花在那儿，擅长就在那儿。
钱花完了可以再赚，时间花了便一去不复返。<br><br>
