CentOS 7中Nginx日志定时拆分实现过程详解
<p><strong>一、编写拆分脚本（splitNginxLog.sh）</strong></p>
<p>
* 因为本例中设置每天0点进行日志的拆分，所以folder和rq均设置采用昨天的日期进行归档。</p>

<strong>二、测试日志拆分脚本</strong></p>
<p>
在.sh文件的存放目录下运行如下语句，测试拆分脚本是否成功。</p>
<p>
<code># sh splitNginxLog.sh</code></p>
<p>
如果提示$'\r': 未找到命令的解决，则有可能是.sh文件编码问题，是因为在Windows编辑器中编写的脚本与在linux中的有一些区别。</p>
<p>
处理方法：</p>
<p>
1. 安装dos2unix用于转化编码</p>
<p>
<code># yum install dos2unix</code> </p>
<p>
2. 转换编码</p>
<p>
<code># dos2unix splitNginx.sh</code> </p>
<p>
三、设置定时自动执行</p>
<blockquote>
<p>
# crontab -l //列出所有的定时任务<br>
# crontab -e //编辑定时任务</p>
</blockquote>
<p>
在其中编写如下语句：</p>
<p>
<code>00 00 * * * bash /root/splitNginxLog.sh</code></p>
<p>
