I have a problem, I had apache Solr installed and it uses localhost for access on webserver...
now I have installed Apache and startet httpd.exe and I get the warning / error:
Could not reliably determine the server’s fully qualified domain name, using 127.0.1.1 for ServerName"
when I stop solr, I can start and use localhost for apache httpd...
but I want to have the possibility to use both webservices, how can I configure Apache to do that? and get access to service not with localhost, but with another domain name or some configuration in httpd.conf
I tried to change the line "ServerName www.example.com:80" in httpd.conf file but no effect,
sorry but I'm pretty new to webservers and Apache, how should I configure that?
You have several things mixed here:
Installing Solr should in no way be related to other questions, unless it is configured to run on port 80. If that is the case, you simply can not run two services on the same port so you have to pick, or just move Solr to 8080 or whatever.
Could not reliably determine... is just a friendly warning and will not prevent any functionality, and it should disappear when you add ServerName www.example.com:80 in httpd.conf
With default settings, Apache will respond to any http request that comes to port 80, so you don't have to configure anything there (and if you want to modify that, use VirtualHost). You can achieve reaching your webserver by other hostnames by editing hosts file on your machine. If you want others to be able to do that, you have to configure DNS (which is separate issue)

I have already installed an Apache HTTP server in my RedHat system, now I need to install a Bitnami application package which contains another Apache. So I am wondering how to make them not disturbing each other?
I guess I need to configure different ports for the two HTTP server. But what if one has 8080 and another has 9090, will we visit http://[ServerName]:8080/something.html and http://[ServerName]:9090/something.html? I think this way is quite inconvenient. Am I wrong or any better idea?
My advice would be to do something like this.
Have one Apache instance listen in port 80 and the other one in port 8080 for example. The Apache instance that listens in port 80 can act as a proxy to the other Apache (port 8080) using the ProxyPass and ProxyPassReverse directives.
https://httpd.apache.org/docs/2.4/mod/mod_proxy.html
You would need to define prefixes or virtual hosts and inside them add ProxyPass directives.
I don't know to what kind of user those applications are targeted to but the usual end-user is not used to enter ports when browsing the web.
If you like to use the ports, go for it, but I would recommend using Name-based Virtual Host
so you could use different domains or subdomains to each application.
In addition to the example provided by the docs (in where they just point to different folders) in this digitalocean page they document how to make redirects to different urls.
I completely agree with EndermanAPM that usual end-user is not used to enter ports when browsing the web. Therefore, I would only allow port 80 to be accessed by the end-users.
Additional to the current solutions I see another one:
avoid messing up the settings of the Apache servers in order to not end-up with some malfunctions of your websites
leave the Apache servers listen on their designated ports (8080 respectively 9090)
install a dedicated proxy in front of the Apache servers. The proxy would listen on port 80 and would define redirect rules that would parse the request and would redirect it to the proper Apache server. (see the attached picture)
I recommend you HA Proxy. It is a very fast and reliable http and tcp proxy. I've been using it in production for years, in front of application servers, web servers and even database servers. Once you get used with its syntax, it is pretty easy to use.
I am aware that introducing a new component into the equation might add another source of potential issues. But I think that the architecture is cleaner. Besides, the two Apache servers will not be disturbing each other as you requested. You can shut down any one of the two and the other one would properly work further.
Sorry if this question is stupid, but I am a newbie when it comes to apache and servers in general and I have been trying but I can only find windows only answers. I'm running an apache server on a mint vm. When I type localhost, it redirects to the page automatically, same as doing 127.0.0.1 or 127.0.1.1. Now, I want to change this to another domain name, but not a website one. Like, I want to change from the word localhost to another word, like 'local'. I have been unable to find answers, I have read about virtual hosts but I don't think that is it because I'm only running one website instance. This is just an example website btw, it's just a index.html file for me to learn how to configure things. I have changed my 000-default.conf to say ServerName thenameIwant but it doesn't work. I noticed it says that this is the last resort host what is the first one?
To be able to use local to connect to your server, you would use local as a domainname which resolves to localhost or 127.0.0.1. You could do this by editing your hosts file. Depending on your os this file is stored in different places. Just google 'Change hosts file [your os]'. And add the following line: local 127.0.0.1.
The default apache server is set to listen for any domain, also local.
I have a VPS with a single IP address and with Virtualmin/Webmin installed. I have created a virtual host *example.com *that will answer to www.example.com (the domain already points to the IP address of the VPS). However, when I access www.example.com I am not seeing the website I have uploaded for example.com but rather the default server:
It works!
This is the default web page for this server.
The web server software is running but no content has been added, yet.
What should I do? Do I have to configure DNS or something?
Yes, you will need to configure DNS for your www.* site if it has not been done already. This www.* alias may have been created automatically when you set up the domain in DNS, but perhaps you will need to specify it explicitly.
Seeing the message "It works!" is a common issue. Apache has a default virtual host which you may want to disable. Exactly how to do that depends on the platform of your web server (it's a good idea to mention the platform and version when asking questions).
For example, if you have shell access to a Debian or Ubuntu machine, you can use the command:
sudo a2dissite default
In virtualmin there may also be an option for this, see for example http://www.virtualmin.com/node/15854
Once you have DNS set up and the www.* domain responding correctly to pings with IP of your server, you will also need to make sure that the virtual host definition for your site includes the www.* alias.
Couldn't find anywhere the answer to question that bothers me for a few days:
According to Apache documentation in virtual host files I should write this:
ProxyPassMatch ^/(.*\.php(/.*)?)$ unix:/path/to/socket.sock|fcgi://127.0.0.1:9000/path/to/your/documentroot/
But Do I have to use another fcgi port for other sites? e.g.
...socket2.sock|fcgi://127.0.0.1:9001...
...socket3.sock|fcgi://127.0.0.1:9002...
Or
...socket2.sock|fcgi://127.0.0.1:9000...
...socket3.sock|fcgi://127.0.0.1:9000...
It works both ways – no errors in logs or on screen. I know that if I would use TCP not UNIX sockets I should use different port for each site (and also it would throw an error if I use the same port) but I'm not sure I understand this Apache syntax.
It all depends how you configure your workers pools for php-fpm.
On centos 7 for example, you will find a www.conf in /etc/php-fpm.d/
This is generally the configuration for port 9000.
You can use the same port for all your virtualhost without any issue.
But if by design you want to use a different port for different virtualhosts, you can just duplicate the www.conf, rename it and edit the file.
Make sure you change the name of the pool at the top. You will find the default name to be [www]. You can edit it to [your_preferred_pool_name]
Then in the listen option you can change the port to what you want.
After restarting php-fpm you will have your [www] pool and your [your_preferred_pool_name] pool.
To configure a virtualhost to use the new pool, just update the ProxyPassMatch configuration by updating the port to your newly defined port in the conf file.
But again, using the same pool (port) for all your virtualhosts should work without any issue.
What are some good ways to do this? Is it even possible to do cleanly?
Ideally I'd like to use packet headers to decide which server should handle requests. However, if there is an easier/better way let me know.
It's impossible for both servers to listen on the same port at the same IP address: since a single socket can only be opened by a single process, only the first server configured for a certain IP/port combination will successfully bind, and the second one will fail.
You will thus need a workaround to achieve what you want. Easiest is probably to run Apache on your primary IP/port combination, and have it route requests for IIS (which should be configured for a different IP and/or port) to it using mod_rewrite.
Keep in mind that the alternative IP and port IIS runs on should be reachable to the clients connecting to your server: if you only have a single IP address available, you should take care to pick an IIS port that isn't generally blocked by firewalls (8080 might be a good option, or 443, even though you're running regular HTTP and not SSL)
P.S. Also, please note that you do need to modify the IIS default configuration using httpcfg before it will allow other servers to run on port 80 on any IP address on the same server: see Micky McQuade's answer for the procedure to do that...
I found this post which suggested to have two separate IP addresses so that both could listen on port 80.
There was a caveat that you had to make a change in IIS because of socket pooling. Here are the instructions based on the link above:
Extract the httpcfg.exe utility from the support tools area on the Win2003 CD.
Stop all IIS services: net stop http /y
Have IIS listen only on the IP address I'd designated for IIS: httpcfg set iplisten -i 192.168.1.253
Make sure: httpcfg query iplisten (The IPs listed are the only IP addresses that IIS will be listening on and no other.)
Restart IIS Services: net start w3svc
Start the Apache service
For people with only one IP address and multiple sites on one server, you can configure IIS to listen on a port other than 80, e.g 8080 by setting the TCP port in the properties of each of its sites (including the default one).
In Apache, enable mod_proxy and mod_proxy_http, then add a catch-all VirtualHost (after all others) so that requests Apache isn't explicitly handling get "forwarded" on to IIS.
<VirtualHost *:80>
ServerName foo.bar
ServerAlias *
ProxyPreserveHost On
ProxyPass / http://127.0.0.1:8080/
</VirtualHost>
Now you can have Apache serve some sites and IIS serve others, with no visible difference to the user.
Edit: your IIS sites must not include their port number in any URLs within their responses, including headers.
You need at least mod_proxy and mod_proxy_http which both are part of the distribution (yet not everytime built automatically). Then you can look here: http://httpd.apache.org/docs/2.2/mod/mod_proxy.html
Simplest config in a virtualhost context is:
ProxyPass /winapp http://127.0.0.1:8080/somedir/
ProxyPassReverse /winapp http://127.0.0.1:8080/somedir/
(Depending on your webapp, the actual config might become more sophisticated. )
That transparently redirects every request on the path winapp/ to the windows server and transfers the resulting output back to the client.
Attention: Take care of the links in the delivered pages: they aren't rewritten, so you can save yourself lotsa hassle if you generally use relative links in your app, like
<a href=../pics/mypic.jpg">
instead of the usual integration nightmare of every link being absolute:
<a href="http://myinternalhostname/somedir/crappydesign.jpg">
THE LATTER IS BAD ALMOST EVERY SINGLE TIME!
For rewriting links in pages there's mod_proxy_html (not to confuse with mod_proxy_http!) but that's another story and a cruel one as well.
Either two different IP addresses (like recommended) or one web server is reverse-proxying the other (which is listening on a port <>80).
For instance: Apache listens on port 80, IIS on port 8080. Every http request goes to Apache first (of course). You can then decide to forward every request to a particular (named virtual) domain or every request that contains a particular directory (e.g. http://www.example.com/winapp/) to the IIS.
Advantage of this concept is that you have only one server listening to the public instead of two, you are more flexible as with two distinct servers.
Drawbacks: some webapps are crappily designed and a real pain in the ass to integrate into a reverse-proxy infrastructure. A working IIS webapp is dependent on a working Apache, so we have some inter-dependencies.
I see this is quite an old post, but came across this looking for an answer for this problem. After reading some of the answers they seem very long winded, so after about 5 mins I managed to solve the problem very simply as follows:
httpd.conf for Apache leave the listen port as 80 and 'Server Name' as FQDN/IP :80.
Now for IIS go to Administrative Services > IIS Manager > 'Sites' in the Left hand nav drop down > in the right window select the top line (default web site) then bindings on the right.
Now select http > edit and change to 81 and enter your local IP for the server/pc and in domain enter either your FQDN (www.domain.com) or external IP close.
Restart both servers ensure your ports are open on both router and firewall, done.
This sounds long winded but literally took 5 mins of playing about. works perfectly.
System:
Windows 8, IIS 8, Apache 2.2
Installing Windows 10 I had this problem: apache(ipv4) and spooler service(ipv6) listening the same 80 port.
I resolved editing apache httpd.conf file changing the line
Listen 80
to
Listen 127.0.0.1:80
That's not quite true. E.g. for HTTP Windows supports URL based port sharing, allowing multiple processes to use the same IP address and Port.
You will need to use different IP addresses. The server, whether Apache or IIS, grabs the traffic based on the IP and Port, which ever they are bound to listen to. Once it starts listening, then it uses the headers, such as the server name to filter and determine what site is being accessed. You can't do it will simply changing the server name in the request
