Error reporting reason:

NGX is not installed_http_ssl_Module module

Solution:

1. check which modules are installed in Nginx

/usr/local/ngxin/sbin/nginx -V

nginx version: nginx/1.12.2
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC) 
configure arguments:

No parameters after configure arguments indicates that no modules are installed
install NGX_http_ssl_Module the module is in the installation directory ofngxin, note the installation directory, find configure and execute:

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

After installation, execute make and make install

make
...
make install

Back up the original nginx, and overwrite the compiled nginx with the original nginx

cp /usr/local/nginx/sbin/nginx  /usr/local/nginx/sbin/nginx.bak
cp ./objs/nginx /usr/local/nginx/sbin/

Check whether the installation is successful

/usr/local/nginx/sbin/nginx -V

nginx version: nginx/1.12.2
