I am new to using Google Cloud Platform and am trying to host a very simple static site. I have followed Google's tutorial for running a basic apache webserver exactly and yet, when I click on the external IP of my site, I am taken to a page that says "This site can't be reached. <my site's IP address> unexpectedly closed the connection ERR_CONNECTION_CLOSED.
Since creating the VM, I have run the following commands:
sudo apt-get update && sudo apt-get install apache2 -y
echo '<!doctype html><html><body><h1>Hello World!</h1></body></html>' | sudo tee /var/www/html/index.html
I also ran ping <site IP address> and saw lines of the form
PING <IP address> 56(84) bytes of data.
64 bytes from <IP address>: icmp_seq=1 ttl=76 time=0.746 ms
I have ensured that the Firewall settings on my VM are set to allow both HTTP and HTTPS traffic.
Why can I not see the simple Hello World page that should be hosted at my site? Do I need to manually start apache? I have tried to and not had any success.
(My VM has Debian 8 as the Boot Image)
UPDATE
At the request of a user below, I ran sudo service apache2 status but got the response below:
apache2.service - LSB: Apache2 web server
Loaded: loaded (/etc/init.d/apache2)
Drop-In: /lib/systemd/system/apache2.service.d

Running sudo service apache2 start did not seem to do anything.
service apache2 status
and
service apache2 start
On the VM did you check the boxes to allow HTTP?
Can you telnet to port 80 of your server ?. Try the following command:
telnet your-server-ip 80
If the above command does not work, then most likely the firewall is blocking port 80. Do you have a second firewall running on your server, such as iptables?.
You need to enable SSL for apache.
(the important bit is making a syslink in the sites-enabled folder of the ssl config file in the site-available folder) that will get it running but you'll need to tinker with the ssl key/cert stuff (check out certbot)
here is a guide: https://hallard.me/enable-ssl-for-apache-server-in-5-minutes/
To those facing this same issue, by default google tries to access URL/IP on HTTPS. But since SSL is not installed, it will not be able to access it. You have two options, 1) Install SSL on the root IP or remove the 's' in the https://xxxxxx address.

to
http://xxxipORwebAddress
I hope it helps

I try to access my node.js server running on Ubuntu. My PC is connected with TP-link router. Now, I want to access node services from other IP(not from my local host or local IPs). What can I do? I used following code.
Note: This server works fine and accessible from local IP but can't access from my public IP
http.listen(6000,"0.0.0.0",function(){
log.info("server started");
})
You have to use :-
iptables -A OUTPUT -p tcp --sport 8080 -j ACCEPT
for the outgoing rule (not dport). Apart from that, maybe there's an earlier rule that blocks the traffic? Try iptables -L.
Ubuntu have very good firewall and default system is not allow to external IP to response
In express and node js or any server like that
http.listen(6000,"0.0.0.0",function(){
log.info("server started");
})
It will work on your IP, localhost and public IP
but on external IP can't access it
first of all replace
localhost -> 0.0.0.0
when you want to run frontend and backend simultaneously
then it is better to use public IP directly instead of 0.0.0.0
If you are using ubuntu then we need to change in firewall settings using ufw
UFW is installed by default on Ubuntu. If it has been uninstalled for some reason, you can install it with apt-get:
sudo apt-get install ufw
then
sudo nano /etc/default/ufw
check this line and make it yes
IPV6=yes
save file using Ctrl-X to exit the file, then shift + y to save the changes that you made, then ENTER
At any time, you can check the status of UFW with this command:
sudo ufw status verbose
By default, UFW is disabled so you should see something like this:
Output:
Status: inactive
Not most important point
sudo ufw allow portNumber // here portNumber is port-number in integer
in your case
sudo ufw allow 6000
and allow
sudo ufw allow http

I have installed nginx on my AMI by yum
sudo yum install nginx
And then, I open all port in my AMI security group
All traffic - All - All - 0.0.0.0/0
And then, I start nginx by command
sudo service nginx start
And then, I access my nginx web service by http://public-ip
but I cannot access by this way.
I try to check the connection in my server.
ssh my_account#my_ip
And then,
wget http://localhost -O-
And It worked fine.
I cannot figure out what is the root cause, and then I change nginx port from 80 to 8081 and I restart the nginx server.
And then, I try to access again. It worked fine. WTH...
http://public-ip:8081
I don't know exactly what is going on?
Could you tell me what is the problem.
I see a few possibilities:
You are blocking the connections with a firewall on the host.
Security Group rules disallow this access
You are in a VPC and have not set up an Internet Gateway or route to host
Your Nginx configurations are set to explicitly listen on host and port combinations such that it responds to "localhost" but not to the public IP or host name. You could post your Nginx configs and be more specific about how it doesn't work when you try remotely. It is timing out? Not resolving? Receiving an HTTP response but not what you expected?
I have got installed CentOS 7 under virtual envirment.
It has proper hostname so I can ping it and it has acccess to internet inside of it and I can ping by IP and host name outside of it. Also It has working Apache and its test page is fine that has been checked locally.
Now I would like to get access to this test page from the MS Windows but I cannot. (I can ping CentOS by IP and hostname.)
Has it something to do with Iptables or firewall?
And this link doesnt help as well https://serverfault.com/questions/459267/enabling-http-access-on-port-80-for-centos-6-3-from-console
I assume some settings should be changed under CentOS but I am not sure which of them.
My question is which steps I have to execute to allow all those things?
Either disable firewalld.service
systemctl disable firewalld.service
systemctl stop firewalld.service
Or allow access to port 80
firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --reload
Also disable SELINUX:
setenforce 0
sed -i 's/^SELINUX=enforcing/SELINUX=disabled/' /etc/sysconfig/selinux
So the answer is a simple one.
I just used Firewall settings to allow http and httpd.
I'm trying to conect to my web page since another computer of my lan through a browser, I put the ip address of my web server (apache linux on centos 7) but it can be able to conect. In my web server i put the following comands:
systemctl enable httpd.service
systemctl start httpd.service
nmap localhost -p 80
It give me all ok, but i can't conect of other computer on my lan.
I have only a switch.
Try disabling SELinux. On CentOS, edit the file /etc/selinux/config. Change the line that says
SELINUX=permissive
to
SELINUX=disabled
Save the file and reboot the server.
Also, stop the default firewall.
sudo systemctl stop firewalld
And to disable it from starting on boot
sudo systemctl disable firewalld
I installed a tomcat7 server on a ubuntu 12.04 box. I simply used "apt-get install tomcat7". I did not install apache2. I can access the default page from localhost:8080, 127.0.0.1:8080, and 192.168.1.201:8080, where the latter is the IP address from my LAN. my end goal is to be able to access the web server from outside the LAN with port forwarding. For now, however, I can't even access it inside the LAN.
Problem:
I can't access the web page from any other computer (windows 7, iPad) on the same LAN! I
get the "connection has timed out" error from the browser.
Question: Can I run tomcat on it's own without installing Apache2 first? This is the current setup and I can access pages hosted on tomcat on the same server, but not over the LAN.
Other information:
I can ping the ubuntu computer from other machines
The ubuntu firewall is disabled (checked via the firewall GUI interface).
I also tried "sudo ufw disable"
I tried: "sudo service iptables stop" and got the message: "iptables: unrecognized service"
I also tried disabling the appArmor firewall:
sudo /etc/init.d/apparmor stop
sudo /etc/init.d/apparmor teardown
sudo update-rc.d -f apparmor remove
I set the router firewall policy to minimum: inbound: accept all; outbount: accept all.
All computers (including ubuntu server) are connected to LAN via wireless
The ubuntu server IP address is static, not DHCP
I checked the SELinux folder and it's empty. I removed it.
Thank you for your help,
Omar
EDIT:
I can connect from within the LAN using ssh (I installed OpenSSH on ubuntu).
ANSWER:
I found the solution to this problem. It turned out there was a firewall active that was blocking the port. The firewall is called "firestarter". Not sure how this was installed, but it can be downloaded from the ubuntu software center. The default inboud policy blocks all ports except for SSH (22). I opened port 8080 and everything worked just fine. The other firewalls (ufw and SELinux) were disabled.
Thank you all again for your help.
Omar
First of all make sure all of the IP addresses are topologically correct, then ping to the your apache server system, If all this succeeds your network is fine.
Now the question are you using the Ubuntu Server edition? if this is the case i believe you can setup apache out of the box.
In case of the Desktop edition you could install it using command line or just install something like XAMP from apache friends.
Make sure your apache Server is started
If you do not already have Apache installed, you can do so now by issuing the following commands:
sudo apt-get update
sudo apt-get install apache2
This is all that is necessary to have a working web server.
I think, "apt-get install tomcat7" doesnt works in Ubuntu. You have to manually download the TAR file & then you can install it with the scripts. Please check whether it is properly installed or not. it should show a Apache Tomcat Homepage # localhost:8080
Also if it is installed properly, check whether it is running on the port 8080, or any other port.
If everything is fine, then disable the firewall of the Server, where you have installed the Tomcat. check for the server IP.
Now from other machine, access that server using http://server_ip:port
This should work fine. No issues should be there.
The other thing, you have metioned in your question, UBUNTU BOX. May be this issue arises due to UBUNTU BOX. If possible, make a clean install of Ubuntu.
