Language performance test

Lower value shows better performance

• C
  

  #include <stdio.h>
  
  int fib(int n) {
      if(n == 1) return 0;
      if(n == 2) return 1;
      return fib(n - 2) + fib(n - 1);
  }
  
  int main() {

      }

• Java

How to run NginX/PHP/MySQL on Mac

Needed to run DRUPAL on Mac

1. Install XCode
2. Install XCode Command Line Tools

XCode > Preferences > Downloads > Command Line Tools

3. Install Homebrew - Similar to MacPorts but better

$ ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"
$ brew doctor
$ brew tap josegonzalez/homebrew-php
$ brew tap homebrew/dupes

4. Install MySQL

$ brew install mysql
$ unset TMPDIR
$ mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp
$ sudo mv /usr/local/opt/mysql/my-new.cnf /usr/local/opt/mysql/my.cnf
$ cp `brew --prefix mysql`/homebrew.mxcl.mysql.plist ~/Library/LaunchAgents/
$ launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

5. Install NginX

$ brew install nginx
$ sudo cp `brew --prefix nginx`/homebrew.mxcl.nginx.plist /Library/LaunchDaemons/
$ sudo sed -i -e 's/`whoami`/root/g' `brew --prefix nginx`/homebrew.mxcl.nginx.plist
$ sudo mkdir /var/log/nginx/

6. Install PHP

$ brew install --without-apache --with-fpm --with-mysql php54
$ sudo cp `brew --prefix php54`/homebrew-php.josegonzalez.php54.plist  /Library/LaunchAgents/
$ sudo launchctl load -w /Library/LaunchAgents/homebrew-php.josegonzalez.php54.plist

How to setup virtual directory with PHP support on Nginx

Setup virtual directory with PHP support.

location /phpmyadmin {
    alias /opt/phpmyadmin/;
    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
    }
}

When to use mutliple virtual directories, seperate and include the configuration.
Create /etc/nginx/conf.d/php.inc

location ~ \.php$ {
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    fastcgi_index index.php;
    include fastcgi_params;
}

Include above file into the virtual directory configuration.

location /phpmyadmin {
    alias /opt/phpmyadmin/;
    include /etc/nginx/conf.d/php.inc;
}
