Server 404, Installation problem? #40

I've followed the installation steps on the compiler wiki for 5 times.
Every time it seems to be installed correctly and apache2 service is running, but request to the route "complier/status" returns a 404.
I also tried other example requests in the wiki, but all returns a 404.
I'm using Ubuntu14.04 on AWS EC2.
Please help, Thank you!

I tried both the installation instructions on the wiki and on the repo readme

Hello @weiway,

Thanks for reporting your issue.
The instructions in the wiki page are Ubuntu 12.04-specific.
Could you give us more info about the exact steps that you're following?

I write a brief how-to below for Ubuntu 14.04 setup so you can give it a try.

After your new EC2 instance is up:

General

  • Run # apt-get update and # apt-get upgrade to get the latest packages.
  • If you have an EBS-backed instance, restart autofs : # service autofs restart
  • Install acl, git and curl if they are not already installed # apt-get install acl git curl

Apache

  • Install apache2 # apt-get install apache2
  • Check which MPM apache2 is currently running. (It should be prefork to use mod_php5)
# apachectl -V | grep -i mpm

Result:
Server MPM:     prefork

Otherwise run # a2enmod mpm_prefork

  • Enable mod_alias: # a2enmod alias
  • Enable mod_rewrite: # a2enmod rewrite

PHP

  • Install PHP5: # apt-get install php5
  • Enable mod_php5: # a2enmod php5
  • Install some PHP extensions that are required: # apt-get install php5-intl php5-curl php5-sqlite

Deployment

  • Create a directory to clone the required repositories (i.e /opt/weiway/ or the default /var/www/)
  • Clone the Arduino core files: git clone https://github.com/codebendercc/arduino-core-files.git
  • Clone the non-standard core files used by compiler: git clone https://github.com/codebendercc/external_cores.git
  • Clone the compiler repo: git clone https://github.com/codebendercc/compiler.git
  • Go to compiler's directory: cd /path/to/your/compiler
  • Go to the Symfony directory: cd Symfony
  • Install dependencies with composer: composer install --no-dev --optimize-autoloader (remove --no-dev if you want to use compiler for development)
  • Change your parameters.yml as necessary(/path/to/compiler/Symfony/app/conf/parameters.yml)
  • Fix Symfony cache/logs issues (assuming that you are already in the Symfony directory):
  mkdir -p app/cache app/logs
  setfacl -R -m u:www-data:rwX -m u:ubuntu:rwX app/cache/ app/logs/
  setfacl -dR -m u:www-data:rwx -m u:ubuntu:rwx app/cache/ app/logs/
  • Clear the cache (if exists) : # php app/console cache:clear --env=prod --no-debug
  • Warmup cache: # php app/console cache:warmup --env=prod --no-debug
  • Create an Apache vhost (i.e /etc/apache2/sites-available/compiler.conf) with the following content:
<VirtualHost *:80>
    ServerAdmin [email protected]
    ServerName compiler.yourdomain.com
    DocumentRoot /path/to/compiler/Symfony/web
    DirectoryIndex index.php
    SetEnv APPLICATION_ENV "production"

   <Directory /path/to/compiler/Symfony/web>
        Options -Indexes +FollowSymLinks +MultiViews
        Require all granted
        AllowOverride All
    </Directory>
</VirtualHost>
  • Enable the vhost: # a2ensite compiler
  • Restart apache2: # service apache2 restart

Now to see if the setup was successful, run : curl http://your_ip/status and you should expect {"success":true,"status":"OK"} as a response. If you don't get a successful return message try curl http://your_ip/app_dev.php/status to see if it is a cache issue.

For any problems refer to /var/log/apache2/error.log and /path/to/your/compiler/Symfony/app/logs/

I hope it helped. Let me know if you have any questions.

Thank you for answering!

This time I followed your instruction for Ubuntu14.04 step by step.

At first the server still reponse with a 404 error, but I then disabled an apache site with a2dissite 000-default.conf command ( only left compiler.conf in /etc/apache2/site-enabled folder), then server will reponse to /status request with correct json message.

However, the request to /myauthword/apiversion will return a 500 error.
But if i entered wrong auth word or api version number server will response with a json.

Here is the line in the /var/log/apache2/error.log for the api post request with 500 status

[Wed Sep 09 23:11:18.094677 2015] [:error] [pid 28749] PHP Fatal error: require_once(): Failed opening required 'System.php' (include_path='.:/usr/share/php:/usr/share/pear') in /var/www/compiler/Symfony/src/Codebender/CompilerBundle/Handler/CompilerHandler.php on line 17

Thank you very much!

ps. In your installation guide, commands to enable mod_alias, mod_rewrite, mod_php5 didn't work, I used the following:
a2enmod php5
a2enmod alias
a2enmod rewrite

I've updated my guide and fixed the mod_ prefixes.

Regarding API setup.

  • Have you set myauthword to authorizationKey key in parameters.yml?
  • Did you cache:clear after you changed your parameters.yml?

Example

  • Lets say we have set githubCompiler as value in authorizationKey.
  • Clean the cache: # php app/console cache:clear --env=prod --no-debug
  • Try: http://your_ip/githubCompiler/v1 and http://your_ip/githubCompiler/v1/status/

Let me know if it works.

For further information see here

Yes I did setup the authkey in parameters.yml (which is inside /var/www/compiler/Symphony/app/config/)

I did clean the cache following your command
php app/console cache:clear --env=prod --no-debug returned Clearing the cache for the prod environment with debug false
php app/console cache:clear --env=dev --no-debug returned Clearing the cache for the prod environment with debug true

The results are:
http://myIP/status will return 200 with {"success":true,"status":"OK"}
http://myIP/wrongAuthKey/v1 will return 200 with {"success":false,"step":0,"message":"Invalid authorization key."}
http://myIP/authKey/wrongVersion will return 200 with {"success":false,"step":0,"message":"Invalid API version."}
http://myIP/authKey/v1 will return a 500 error with no message
http://myIP/authKey/v1/status/ will return a 404 error with a html

The error.log inside /var/log/apache2/ has following content for the failed request with 500 error code:
[Thu Sep 10 17:28:45.565717 2015] [:error] [pid 1452] PHP Fatal error: require_once(): Failed opening required 'System.php' (include_path='.:/usr/share/php:/usr/share/pear') in /var/www/compiler/Symfony/src/Codebender/CompilerBundle/Handler/CompilerHandler.php on line 17

which complains the failure of opening System.php

My compiler server is hosted at 52.88.1.188, authKey is code, you can go and see for yourself

Any suggestions?

There are some missing steps in the how-to which might cause a confusion to inexperienced people... Anyway... I experienced the same issue as @weiway. The solution seems to be to install php-pear (sudo apt-get install php-pear).

now fixed

for anyone running into similar issues, heres what i found

  • if you downloaded the the compiler from github, you need to edit your yml file
  • make sure your yml director paths include the master branch folder

before

[snip]
    arduino_cores_dir: /opt/codebender/codebender-arduino-core-files
    external_core_files: /opt/codebender/external-core-files
    clang: /opt/codebender/codebender-arduino-core-files/clang/v3_5/bin/clang
[snip]

after

[snip]
    arduino_cores_dir: /opt/codebender/codebender-arduino-core-files/arduino-core-files-master
    external_core_files: /opt/codebender/external-core-files/external_cores-master
    clang: /opt/codebender/codebender-arduino-core-files/arduino-core-files-master/clang/v3_5/bin/clang
