“Uncomment the correct lines in “location ~ .php$ {“ section” —

Can you Give little eloboration on this. What settings needs to uncomment. I am getting. 502 bat gateway error. whil accessing a PHP page.

Thanks in advance

My bad. Typo… You can delete my comments. it worked.

No problem, glad you got it working =]

Hello,

I configured my servet just like this but my server is not behaving as expected when I try to access a URL that doesn’t exist.

If I try to access http://myserver/3i1idaosdj (a file that does not exist), I get a 500 Internal Server Error.

If I try to access http://myserver/3i1idaosdj.php (a file that does not exist and the URL ends with .php), I get a message saying “No input file specified”.

Accessing the error log, I got the following message:

2012/08/08 03:18:45 [error] 6699#0: *1 rewrite or internal redirection cycle while internally redirecting to “/index.html”, client: my ip, server: localhost, request: “GET /3i1idaosdj HTTP/1.1”, host: “my server ip”

Also, I configured the 404 error page in /etc/nginx/sites-available/default, via:

error_page 404 /404.html;

And 404.html is properly placed in the website folder. Why this is not working?

In the nginx config make sure you updated: server_name example.com;

And replaced example.com with your actual domain name and then test it through the web.

If you just have an IP and not a domain name you can use that as well.

If you’re still having a problem paste us your nginx config and we can help go through it.

Thanks

Here is my /etc/nginx/sites-available/default code:

http://d.pr/n/KgJt

You have a small typo near the end :

location ~ /.ht { deny all; } }

It should be:

location ~ /.ht/ { deny all; } }

However, this wouldnt be the cause for the issues you were having. I did test the URL via the IP for both a non-existent file, received the 404, and a non-existent file ending in .php and got good 404 errors for both.

Visiting the IP directly I did get the phpinfo() page, I’m assuming you made an index.php?

If that’s the case I don’t really see what issue you are having unless you are uploading php files and they aren’t displaying or if you are uploading static content and having an issue.

What URL are you hitting that you should see something and you dont? And can you show me the file listing in: /srv/www/test/

Thanks.

raiyu, thanks for the help, I solved the problem today, that’s why you got the 404 working.

Here is my modified /etc/nginx/sites-available/default code. Hope it helps in case that someone have the same issue:

Hello. Your tutorial is good. I want to change the current document root directory to “home/user101/box/devs” How can I do that? I’m new to Nginx. Thanks and more power!

Inside the server { } directive there is a root directive that which specifies where to serve files from:

server { root /home/user101/box/devs; }

i try everyting this is fun but really boring;

500 Internal Server Error

nginx/1.1.19 all the time.

but still better than regular hosting. i am going old school LAMP :D

Check your error log and paste why its returning a 500 error for you.

For security reasons any error will return 500 publicly so as not to distribute any sensitive error messages to the public internet.

It could be something as simple that the PHP script you are executing is being executed but is simply failing because of a code issue.

I’m getting a 502 gateway error…

[error] 15479#0: 1 connect() failed (111: Connection refused) while connecting to upstream, client: ...*, server: 141.0.170.212, request: “GET /info.php HTTP/1.1”, upstream: “fastcgi://127.0.0.1:9000”, host: “141.0.170.212”

Seems to me that the server is refusing connections to port 9000, but I’ve not made any changes to disallow this (nor any to allow it really).

Thanks.

I’ve not solved the issue directly, but I found that the issue could of been I was using Ubuntu 12.10 x64. I’m now using 12.4 x32 and it works perfectly.

Nice HowTo! Now, as a totally n00b to nginx, how do I configure it to redirect all WAN incoming traffic to a virtualserver while sending all LAN traffic to another virtual server? Thanks in advance, Martin

There are a number of ways to do this, the easiest way is to setup a separate domain / server_name / server block for the internal LAN.

Then for internal communication since you would be communicating on different IPs that would take care of it.

So the public communication would be over the public IP with the listen directive, while the local communication can be done by setting the listen directive to a private LAN IP. Since the LAN IP is not visible from the public internet any communication that occurs over it is automatically private.

And it doesn’t require any complex proxying rules.

I am having memory issue with ubantu 12.04 droplet. After installing nginx/php/mysql and web2py I have found that memory is is slowly used up and needed to reboot to free up. So discarded every thing and rebuild the droplet. Nothing is installed on it, still memory issues remains.

Here is the detail: https://docs.google.com/open?id=0B3z4rMfDQSHIcmpLZ1pqU1JVbjg

Depending on the process you are running memory isn’t always freed up, instead it is cached until another application needs to use it.

If you are consistently having issues I’d recommend you install swap space according to this tutorial: https://www.digitalocean.com/community/articles/how-to-add-swap-on-ubuntu-12-04

This should help in your situation and if you start using a lot of swap you may want to resize to a larger virtual server because you may just be running more applications than your virtual server can support.

After doing some experiment with ubantu, found that even in a new instance if you just run these : #sudo apt-get update #sudo apt-get -u upgrade the used memory will not be freed long after the execution. It is only freed after you do a reboot.

so I destroyed my ubantu instance and created a fedora instance:

Last login: Thu Dec 20 20:13:36 2012 from 180.234.111.171 [root@fedora01 ~]# free -m total used free shared buffers cached Mem: 497 428 68 0 33 359 -/+ buffers/cache: 35 461 Swap: 0 0 0 [root@fedora01 ~]# history 1 free -m 2 free -m 3 yum update 4 free -m 5 free 6 free -m 7 top 8 free -m 9 top 10 free -m 11 history [root@fedora01 ~]#

The above are all the commands that was run after the instance created. RAM is already used up and i guess wont be released until a reboot.

RAM should get freed up as different applications are started and start using memory since a lot of memory gets used as cache and will be automatically replaced.

Also if you add swap space: https://www.digitalocean.com/community/articles/how-to-add-swap-on-ubuntu-12-04

You can give your virtual server a buffer so if you do end up using more RAM than your system has you will see your swap space grow. Otherwise you should see that the cached memory is released and used up by other applications without increasing swap usage.

If you are looking for a tutorial to install and configure a LEMP Stack on Debian (6) Squeeze. I have published a guide on my website located at http://techhelper.info/12/30/2012/debain-squeeze-lemp-stack/ .

I followed the instructions to the letter (except using 12.10 32bit) and when I look at the info.php, I get:

“The page you are looking for is temporarily unavailable. Please try again later.”

Fixed. Needs this (socket instead of port?):

            #fastcgi_pass 127.0.0.1:9000;
            # With php5-fpm:
            fastcgi_pass unix:/var/run/php5-fpm.sock;
            fastcgi_index index.php;
            include fastcgi_params;

@moebis I had the same problem. Changing to a socket connection made it work for me. Thanks!

+1 withe the same problem as @moebis and @natebird

One thing I found with this tutorial is that it doesn’t seem to build the connection between php5 and mysql. I’m still working on getting WordPress to run, but I needed to run a ‘sudo apt-get install php5-mysql’ and that connected them.

Having permission issues using Transmit by Panic to connect to my droplet. Seems I can login, but all the folders are owned by root. I now can’t login as root, and my user can’t change ownership. What to do?

SSH to the server as root and change the ownership of the directory that your user logins into.

chown username:group /directory/user/logs/in/to

And then the user will be able to login and upload files.

Tried this but end up with an error when viewing info.php. The page you are looking for is temporarily unavailable. Please try again later.

From the error.log “2013/01/21 18:05:46 [crit] 6027#0: *1 connect() to unix:/var/run/php5-fpm.sock failed (2: No such file or directory) while conne$”

Any ideas?

Looks like fpm was either not running or not configured do a quick :

ps auxw | grep php-fpm

To see if its listed in your process list.

@dvogel That’s because php5-fpm doesn’t use sock so you can find “php5-fpm.sock” under path “/var/run/”;

If you follow this instruction to use sock, you have to modify the default configuration for php5-fpm. To do this, edit: “/etc/php5/fpm/pool.d/www.conf” and change this line:

“listen 127.0.0.1:9000”

to

“listen /var/run/php5-fpm.sock”

the same path as you specified in nginx’s default settings.

After this you should restart your php5-fpm service by using:

$ sudo service restart php5-fpm

Then you can check if there is a php5-fpm.sock file under /var/run/, if so, you’ve done a good job.

BTW, the newest version of php5-fpm has already use sock as default listening option, but it only available for php 5.4 +. Since Ubuntu’s apt-get will install PHP 5.3 as default, so you have to change this option, or use the old way.

I have followed the steps meticulously but i find that when i go to http://youripaddress/info.php it just asks me if i want to download the info.php file… I think the <?php phpinfo(); ?> code should echo some settings but for me that page doesnt show but instead asks me to download/save the info.php file…is that correct? can anyone help me figure out what im doing wrong? using Ubuntu 12.10 x64 Server
thx

@wortheverythingbut: I experienced the same thing, but if you’ll notice that the file has ‘improved’ since this article. The file, info.php, we created showed for me when I read this, http://maketecheasier.com/install-lemp-server-in-ubuntu/2012/05/29.

It’s the config file, /etc/nginx/sites-available/default, in the section about fast.cgi. Read the article to address the changes with commenting and uncommenting.

Actually, on Ubuntu 12.04 x32, PHP doesn’t work with sockets, it works with ports (see Albert’s comment above). Using sockets on 12.04 will give you a nice 502 Bad Gateway when accessing any PHP page.

However, if you’re on Ubuntu 12.10 x32, sockets like in this tutorial, will work (tested). It would be nice to update the tutorial, since it refers to 12.04 and not 12.10

My server is on a local lan, but I put in the external IP instead of the 192-- IP. Not sure if that is why Chrome just downloads the PHP file instead of showing a processed info.php in the browser window.

great tuts… these are helpful php packages as well and fixed my featured image resize output in wordpress… sudo aptitude install php5-common sudo aptitude install php5-gd sudo aptitude install php5-cli sudo aptitude install php5-curl

I can’t seem to get the nginx file changed to how the config. instructions demonstrate. The last portion is where I’m having trouble:

What needs to be uncommented or added too or what? Or do I just leave as is.

Can someone give me some hints please.

pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000W

    location ~ \.php$ {
            #fastcgi_pass 127.0.0.1:9000;
            # With php5-fpm:
            fastcgi_pass unix:/var/run/php5-fpm.sock;
            fastcgi_index index.php;
            include fastcgi_params;

@vic.palm2849 What you have there is correct. I’m betting you’re getting a “This page is not available…” error right? If so, the fix was already stated above, but all you have to do is:

1. sudo nano /etc/php5/fpm/pool.d/www.conf
2. comment out the line for: listen = 127.0.0.1:9000
3. ADD: listen = /var/run/php5-fpm.sock
4. sudo service php5-fpm restart

I followed another tutorial to install Passenger and nginx to run my Ruby on Rails sites (https://www.digitalocean.com/community/articles/how-to-install-rails-and-nginx-with-passenger-on-ubuntu). This is up and running and works fine.

I’ve now ready to upload my old PHP sites so installed php5-fpm and configured as this current article shows. I then added a new server block to my nginx config file (/opt/nginx/conf/nginx.conf), like so:

server { listen 80; server_name localhost; root /home/rich/www/phptest; index index.php index.html; passenger_enabled off;

    location / {
            try_files $uri $uri/ /index.php;
    }

    location ~ \.php$ {
            #fastcgi_pass 127.0.0.1:9000;
            #include fastcgi_params;
            fastcgi_pass unix:/var/run/php5-fpm.sock;
            fastcgi_index index.php;
            include fastcgi_params;
    }
}

Next I created index.php with the following contents: <?php phpinfo(); ?> And as a sanity check, index.html which outputs a basic HTML page. Restarting PHP5-FPM and nginx and loading the pages, the HTML works fine, but the PHP page is completely blank. No error message or status code shown.

Tailing nginx’s access.log shows: “GET /index.php HTTP/1.1” 200 31 “-” “Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:19.0) Gecko/20100101 Firefox/19.0” There isn’t any entry in its error.log. If I stop the php5-fpm service, I see a 502 Bad Gateway error in the browser and log. Restarting shows the blank page again.

Does anyone have any ideas on how to resolve this? Anything I can try? If you need any more info, just ask.

The index.php contents were simply the php tags and phpinfo();

abunchofletters i’m getting a blank phpinfo page too my conf looks like yours/article

hey i made it work by placing:

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

before

include fastcgi_params;

if you have a 502 check the file: /etc/php5/fpm/pool.d/www.conf for me the listen directive was set for port 9000 rather than a unix socket, so I had to change the nginx conf to reflect that

I tried the samething for subdomain but did not work, is there something extra for a subdomain ?

Have you taken care of this vulnerability here - https://nealpoole.com/blog/2011/04/setting-up-php-fastcgi-and-nginx-dont-trust-the-tutorials-check-your-configuration/

Marvelous!

It took me a solid minute to figure out that I had to uncomment (delete the # symbol) specific sections before I saved. Thanks for the solid tutorial yo!

I tried this before and It worked, right now I have new vps, I guess updated nginx has different configuration, I searched and turns out this,

fastcgi_pass 127.0.0.1:9000;

#fastcgi_pass unix:/var/run/php5-fpm.sock;

if fastcgi_pass unix used, you get the 502, which scares me a lot, but uncomenting 127… works, you should try again, the topic needs update

I need help now, I am trying this since tomorrow, how can i add www to my nginx confs, I am trying my old configuration file, but it does not seem to work, how can i do this ?

“o apt-get install php5-fpm” is not working anymore.

I get an error E: Couldn’t find package php5-fpm

You can add www by simply adding another value after the server_name directive: server_name www.mydomain.com mydomain.com;

@martin.taklaja try running apt-get update first.

worked like a charm with @brian_sands tip

hi, how can I create tumblr like subdmains, for example, username.tumblr.com, and how should I add cnames for this purpose on my dns ? thank you

^: You can set up a wildcard A record (* A 1.2.3.4) where 1.2.3.4 is your droplet’s IP address. After that you can add a server alias of *.yourdomain.com by simply passing it as an additional argument to the server_name directive.

I should write " * " as hostname and I should write ip adress as my " ip adress " as an A record, and I should add " *.domain.com " as a server_name to nginx,

to get subdomain variable should I use this ?, rewrite ^/([/0-9a-zA-Z-_]+)/$ /tab.php?tab_id=$1 last;

thank you for your help :), I hope I am not bothering you

Fixed it… the key is here:

location ~ .php$ { #fastcgi_pass 127.0.0.1:9000; # With php5-fpm: fastcgi_pass unix:/var/run/php5-fpm.sock;

change to:

location ~ .php$ { fastcgi_pass 127.0.0.1:9000; # With php5-fpm: #fastcgi_pass unix:/var/run/php5-fpm.sock;

which is just swapping which line has the # in front of it.

BTW, That was in /etc/nginx/sites-available/default

@(Posted May 20th, 2013 18:08): Sorry, it should be a wildcard CNAME record not an A record. Yes, what you said is correct.

Hi,

I’ve been stuck with no idea what went wrong at the info.php creation step. I followed everything to that point exactly, and then when I went to save the info.php in the /usr/share/nginx/www patj i get [ Error writing /usr/share/nginx/www/phpinfo.php: No such file or directory ].

Now I have no idea what i missed. Any help would be appreciated, thanks.

I’m on Ubuntu 13.04 x64 Server by the way.
