ubuntu installation nginx one

Recently, I feel like I haven’t been exposed to lnmp development environment setup, configuration, etc. for a long time. As a result, sometimes I can’t remember when using it, so I configure the configuration environment separately and practice
I first tried to install it with apt-get install nginx, but a very strange error occurred, causing apt-get remove nginx to also fail. Finally, I passed

find / -name '*nginx*' | xargs rm -rf

Deleted all the nginx files, but the reinstallation still failed. I temporarily gave up the apt-get installation method and used the source code method

su

cd /usr/local/src

wget http ://nginx.org/download/nginx-1.9.6.tar.gz

tar -zxvf nginx-1.9.6.tar.gz

cd nginx-1.9.6

./ configure --prefix=/usr/local/nginx

make

make install

ln -s /usr/local/nginx/sbinb/nginx /etc/init.d

when I An error occurred during startup

It may be because the previous apt-get installation failed, or other programs occupy this port. Kill the program occupying this port

sudo fuser -k 80/tcp

Restart , no problem

/etc/init.d/nginx

But when I run /etc/init.d/nginx stop, something goes wrong again, invalid stop. I am very confused, how to stop nginx? I just use this

killall -9 nginx

and it’s done. When starting, just /etc/init.d/nginx and it’s ok. When stopping, just killall -9 nginx

Then the browser runs localhost: 80 Done

The above introduces the installation of nginx on ubuntu, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
