Step 1: Manually Building the Repo.          Two type method of building the Repo. :- Sub Step 1:  Everything Under a Root  To build a repo including all files recursively under /path/to/root, invoke HHVM like this: $ sudo hhvm --hphp -t hhbc -v AllVolatile=true --input-dir /var/www/html Sub Step 2:  Manual List of Files Instead of a directory, you can also pass it an explicit list of filenames to put in the repo or a master file that contains all of the files, one per line, that should be put in the repo. (Keep in mind that the commands below are generating two separate repos -- you can't add to or remove from a repo once it's been generated!) $ sudo hhvm --hphp -t hhbc -v AllVolatile=true test.php OR  $ sudo hhvm --hphp -t hhbc -v AllVolatile=true --input-list test.txt Example : The test.txt should look like this : /var/www/html/index.php /var/www/html/isrc/a.php /var/www/html/isrc/b.php /var/...

Step 1 First we need to add the HHVM key to your Ubuntu Server with the following command: $ sudo wget -O - http://dl.hhvm.com/conf/hhvm.gpg.key | sudo apt-key add - Step 2  Next we are going to add the HHVM source to your sources list with the following command: $ sudo echo deb http://dl.hhvm.com/ubuntu trusty main | sudo tee /etc/apt/sources.list.d/hhvm.list Step 3  Now that we added the key and sources it is a good idea to run and update with the following command: $ sudo apt-get update Step 4  Now we can install HHVM with the following command: $ sudo apt-get install hhvm Step 5   Make it start on boot by running the command: $ sudo update-rc.d hhvm defaults Step 6  HHVM includes an excellent script to install FastCGI based on web server you have installed. Run it with the following command: $ sudo /usr/share/hhvm/install_fastcgi.sh Step 7  Note: On Apache there have been issues with hhvm_proxy_fcgi.conf not matching the defaul...

ENABLE CROSS-DOMAIN   Browser does not allow cross domain AJAX requests due to security issues. Cross-domain requests are allowed only if the server specifies same origin security policy. To enable CORS, You need to specify below HTTP headers in the server. Access-Control-Allow-Origin – Name of the domain allowed for cross domain requests. * indicates all domains are allowed. Access-Control-Allow-Methods – List of HTTP methods can be used during request. Access-Control-Allow-Headers – List of HTTP headers can be used during request. In PHP, you can use the below code to set the headers. header('Access-Control-Allow-Origin: *'); //I have also tried the * wildcard and get the same response header("Access-Control-Allow-Credentials: true"); header('Access-Control-Allow-Methods: GET, PUT, POST, DELETE, OPTIONS'); header('Access-Control-Max-Age: 1000'); header('Access-Control-Allow-Headers: Content-Type, Content-Range, Content-Di...

Step (1.) How to Create a New User :- we did all of the editing in MySQL as the root user, with full access to all of the databases. However, in the cases where more restrictions may be required, there are ways to create users with custom permissions. Let’s start by making a new user within the MySQL shell: CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'password'; this point new user has no permissions to do anything with the databases. In fact, if new user even tries to login (with the password, password), they will not be able to reach the MySQL shell. Therefore, the first thing to do is to provide the user with access to the information they will need. GRANT ALL PRIVILEGES ON * . * TO 'newuser'@'localhost'; The asterisks in this command refer to the database and table (respectively) that they can access—this specific command allows to the user to read, edit, execute and perform all tasks across all the databases and tables....
