8. Create authentication file

# htpasswd -c /etc/httpd/passwd/svn-users svn-user-name

Prevent form submit from submiting multiple times by jQuery

If you need to assign a click function dynamically, there is a way to ensure the click function is only assigned once and not duplicated.


Now I show one way based on jquery




       

                        # test
            if ($_POST) {
                print_r($_POST);
                $loop = 100000000;
                for ($i = 0; $i < $loop; $i++) {
                    $b+=1;
                }
                echo 'Completed';
            }
            ?>

   # rpm -ivh http://dev.mysql.com/get/mysql-community-release-el6-5.noarch.rpm

2. View Repo of mysql
   #  less  /etc/yum.repos.d/mysql-community.repo


# Enable to use MySQL 5.5
