I do not find the hhtpd.conf in /var/www or /var/www/html but i found a lighttpd.conf in /etc/phpmyadmin ... is it this file ?

No.
It should be in /etc/apache2 or /etc/httpd

but no way to projeqtor 🙁

If you have /var/www/html, just move projector folder here.

i'd move the folder on /var/www/html/ and write 127.0.0.1/projector and ... it's works !

😆 😆 😆 :cheer: :cheer: :cheer:

now, i have a first projeqtor base on 1and1, and i would like transfert it on my local server ... how can i do that ?

Install phpMyAdmin (should have equivalent in hosting I hope)
Export database and reimport locally.

ok, i already have php admin. I'll try it.
another question:
how can I joined in a local to joined the serveur machine wich is a 192.168.100.199 IP fix ?

In another computer, could i connect with

192.168.100.199/localhost/projeqtor ( is it correct?)

how can i do a bridge beetween 192.168.100.199 and 127.0.0.1/projeqtor/ ??

In another computer, could i connect with

192.168.100.199/localhost/projeqtor ( is it correct?)

No, just 192.168.100.199/projeqtor
Your firewall must let the flow pass, and your apache must accept remote connections.
If my remembering is correct, you must have

Listen *:80

in httpd.conf

# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/000-default.conf

Listen 80

Listen 443

Listen 443

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

In ports.conf on apache2 folder.

everything is ok, my data base is import on my new server, thank you very much for your help and your job !

I just have a problem, I can't send a mail, It's work before with 1and1 hosting but not work now on new server .... 🙁

Possibly because you don't have a local SMTP Server...

it means not sending mails ?

I just remove the "chemin du sendmail" and it's work !
