ubuntu1404 completely delete nginx

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

<span>sudo</span> apt-get install nginx</code>

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });

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.
