Possible problems in the process

Why does an error occur when http: // localhost/PHPmyAdmin/is enabled?
Not found the requested URL/PHPmyAdmin/was not found on this server. Apache/2.2.9 (UBUNTU) PHP/5.2.6-2ubuntu4 with suhosin-patch server at localhost port 80

This is because the default installation path of phpMyAdmin is not in/var/www/(/var/www/is the root directory of your web service site), so you can create a soft connection. The above command is to create a phpMyAdmin soft link under/var/www. The solution is as follows:

sudo ln -s /usr/share/phpmyadmin/ /var/www/

How to Use PHP

Note that ,. PHP files are files that need to be explained by the server, rather than directly running programs on local machines. Generally, you can use the Apache server, or asii server. For example, I did this by installing Apache on a local host, and then
Use

sudo /etc/init.d/apache2 start

After the local server is opened, you can access the local server through http: // localhost/. Then, you can open Hello under the directory of the local server. PHP, that is, http: // localhost/hello. PHP

The local address of localhost is/Var/WWW

Basic Apache Authentication

First, make sure that you want to set the user authentication folder, for example,/var/www/test /.

Remove the annotator before configuring accessfilename. htaccess in the/etc/apache2/apache2.conf file,

Add the following content to the configuration file apache2.conf or httpd. conf:

<Directory "/var/www/test/">Options Indexes MultiViewsAllowOverride AuthConfigAllow from all</Directory>

Create a. htaccess file in the/var/www/test/folder. The file content is

AuthName "You need to have the privilege to view this page ,Please log in : AuthType BasicAuthUserFile /etc/apache2/authpwd Require user maturn test #maturn 

Create a password file and set a password for the user. Enter the command

htpasswd -c /etc/apache2/authpwd maturn   

The authentication is basically completed. EnterLocalhost/testTo verify whether it is successful
