Server 404, Installation problem?

[weiway]

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 yourname@example.com
    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.

[weiway]

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

[dastergon]

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

[weiway]

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

[weiway]

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).

i have an issue with the authKey

compiler

{
"success": true,
"status": "OK"
}

compiler with 'thirty' as authKey

404

compiler with 'thirty' as authKey and v1

{
"success": false,
"step": 0,
"message": "Invalid authorization key."
}

yml file

parameters:
    locale: en

ran

$ php app/console cache:clear --env=dev --no-debug
$ php app/console cache:clear --env=prod --no-debug
$ sudo service apache2 restart

still getting authKey error

{
"success": false,
"step": 0,
"message": "Invalid authorization key."
}

any insight would be helpful

okay, so i've made some progress,
now, if i use postman

[32teeth]

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

    external_core_files: /opt/codebender/external-core-files
