1. Execute the command first:
1.1 Delete nginx, –purge including configuration files
<code>sudo apt-<span>get</span><span>--purge remove nginx</span></code>
1.2 Automatically remove all unused software packages
<code><span>sudo</span> apt-get autoremove </code>
1.3 List nginx-related software
<code>dpkg --<span>get</span>-selections|grep nginx</code>
<code>执行<span>1.3</span>的结果: stephen@stephen<span>-OptiPlex</span><span>-</span><span>390</span>:~$ dpkg <span>--</span>get<span>-selections</span><span>|</span>grep nginx nginx install nginx<span>-common</span> install nginx<span>-core</span> install </code>
1.4 Delete 1.3 Check out the software related to nginx
<code>sudo apt-<span>get</span><span>--purge remove nginx</span> sudo apt-<span>get</span><span>--purge remove nginx-common</span> sudo apt-<span>get</span><span>--purge remove nginx-core</span></code>
In this way, you can completely uninstall nginx including the configuration file
2. Check the running process of nginx, if there is one, kill it
<code>ps -ef <span>|grep nginx</span></code>
See if nginx is still started, generally execute After completing 1, nginx is still starting, as follows:
<code><span>stephen</span>@stephen-<span>OptiPlex</span>-<span>390</span>:~$ ps -ef |grep nginx <span>root</span><span>7875</span><span>2317</span><span>0</span><span>15</span>:<span>02</span> ? <span>00</span>:<span>00</span>:<span>00</span> nginx: master process /usr/sbin/nginx <span>www</span>-<span><span>data</span> 7876 7875 0 15:02 ? 00:00:00 nginx: worker process</span><span>www</span>-<span><span>data</span> 7877 7875 0 15:02 ? 00:00:00 nginx: worker process</span><span>www</span>-<span><span>data</span> 7878 7875 0 15:02 ? 00:00:00 nginx: worker process</span><span>www</span>-<span><span>data</span> 7879 7875 0 15:02 ? 00:00:00 nginx: worker process</span><span>stephen</span><span>8321</span><span>3510</span><span>0</span><span>15</span>:<span>20</span> pts/<span>0</span><span>00</span>:<span>00</span>:<span>00</span> grep <span>--color=auto nginx</span></code>
3. kill nginx process
<code><span>sudo</span> kill -<span>9</span><span>7875</span><span>7876</span><span>7877</span><span>7879</span></code>
4. Global search for files related to nginx
<code><span>sudo</span> find / -name nginx*</code>
5. Delete all files listed in 4
<code><span>sudo</span> rm -rf file</code>
That’s it Completely deleted nginx
6. Reinstall again
<code><span>sudo</span> apt-get update <span>sudo</span> apt-get install nginx</code>
The above introduces the complete deletion of nginx in ubuntu1404, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
