Configure PHP Environment under MAC

Mac OS X has built-in Apache and PHP, which makes it easy to use. This article takes Mac OS X 10.6.3 as an example. The main contents include:

Launch Apache

Running PHP

Install MySQL

Using phpMyAdmin

Configuring PHP's MCrypt Extension library

Set up a virtual host

Launch Apache

There are two ways of doing this:

Open Web share (Web sharing), System settings Preferences (Preferences), sharing (sharing)

Open terminal (terminal), then (note: sudo requires a password that is the root account password of the system)

Run "sudo apachectl start" and enter your account password so that Apache runs.

Run "sudo apachectl-v" and you will see the Apache version number in Mac OS X 10.6.3:

Server version:apache/2.2.14 (Unix)

Server Built:feb 11 2010 14:40:31

This allows you to enter "http://localhost" in the browser, and you can see that a content "It works!" appears Page, which is located under "/library (Resource Library)/webserver/documents/", which is the default root directory for Apache.

NOTE: When Apache is turned on, "web sharing" is turned on, and the networked user accesses the "/library (library)/webserver/documents/" directory via "http://[local ip]/", via "http://[local IP" /~[user Name] "To access the/users/[user name]/sites/directory, you can disable this access by setting the" Firewall (Firewall) "in" Security "in System preferences.

Running PHP

Run "sudo vi/etc/apache2/httpd.conf" in the terminal to open the Apache configuration file. (If you are not accustomed to the terminal and VI can be set in the Finder to display all the system hidden files, remember the need to restart the Finder, so that you can find the corresponding files, edit as you like, but you need to note that some of the file changes need to open the root account, But on the whole it is safe to use sudo on the terminal to temporarily gain root privileges. ）

Find "#LoadModule php5_module libexec/apache2/libphp5.so", remove the previous #, Save (enter: W at the command line) and Exit VI (enter: Q on the command line).

Run "sudo cp/etc/php.ini.default/etc/php.ini" so that you can configure various PHP functions via php.ini. Like what:

The maximum value of the PHP commit file is adjusted by the following two items, such as the maximum value of the imported data in phpMyAdmin

Upload_max_filesize = 2M

Post_max_size = 8M

, such as using display_errors to control whether or not to display the PHP program error

Display_errors = Off

Run "sudo apachectl restart" and restart Apache so PHP is ready to use.

Run "cp/library/webserver/documents/index.html.en/library/webserver/documents/info.php", That is, copy the Index.html.en file and rename it to info.php in the root directory of Apache.

Run "vi/library/webserver/document/info.php" in the terminal so that you can edit the info.php file in VI. In "It s works!" Add the following "<?php Phpinfo ();?>" and save it. This allows you to see information about PHP in http://localhost/info.php, such as the version number 5.3.1.

Install MySQL

Since MySQL is not preinstalled in Mac OS X, it needs to be installed manually, and the most stable version of MySQL is now 5.1. MySQL provides installation instructions under Mac OS x.

Download MySQL 5.1. Select the appropriate version, for example, MYSQL-5.1.46-OSX10.6-X86_64.DMG is selected here.

Run DMG and you will find 4 files inside. First click Install Mysql-5.1.46-osx10.6-x86_64.pkg, which is the main installation package for MySQL. In general, the installation file will automatically install MySQL to the folder under the same name under/usr/local. For example, clicking Run "mysql-5.1.46-osx10.6-x86_64.dmg" will install mysq into "/usr/local/mysql-5.1.46-osx10.6-x86_64". The default installation is complete.

Click Install 2nd file mysqlstartupitem.pkg, so that MySQL will automatically start automatically when the boot.

Click Install 3rd file Mysql.prefpane, so you will see icon named "MySQL" in "System Preferences", through which you can set MySQL to start or stop, and whether to run automatically when booting. The basic installation of MySQL is complete here.

Add MySQL and mysqladmin aliases to bash's configuration file by running "sudo vi/etc/bashrc"

#mysql

Alias mysql= '/usr/local/mysql/bin/mysql '

Alias mysqladmin= '/usr/local/mysql/bin/mysqladmin '

This can be relatively simple in the terminal by the command to do the corresponding operation, such as after the installation is complete after the root default password is empty, if you want to set the password can be run in the terminal "Mysqladmin-u root password" Mysqlpassword "" to set up, Where Mysqlpassword is the root password. For more information, see b.5.4.1. How to Reset the Root Password.

Note: Mac OS x upgrades or other causes may cause MySQL to boot or boot automatically, and on the MySQL operator panel you will be prompted "Warning:the/usr/local/mysql/data directory is not owned by The ' MySQL ' or ' _mysql ', or under the command line prompt "Can ' t connect to local MySQL server through socket '/tmp/mysql.sock ' (2)", which should be caused in some case/ Usr/local/mysql/data's host has changed, just run "sudo chown-r mysql/usr/local/mysql/data".

Also, using PHP to connect MySQL may error "can ' t connect to local MySQL server through socket '/var/mysql/mysql.sock '", Or use localhost can not connect to MySQL and need 127.0.0.1, because the connection time PHP by default to find/var/mysql/mysql.sock, but Mac version of MySQL changed the location of the file, put in/tmp. The approach is to modify php.ini as follows:

Mysql.default_socket =/tmp/mysql.sock

Using phpMyAdmin

phpMyAdmin is a PHP-developed program for managing MySQL, which is very popular and practical. The ability to use phpMyAdmin to manage MySQL is a very effective way to test the results of the previous steps.

Download phpMyAdmin. Choose the right version, such as the one I chose is the phpmyadmin-3.3.2-all-languages.tar.bz2 version.

Copy the Phpmyadmin-3.32-all-languages folder in "Download (downloads)" To "/users/[user name]/sites" with the name renamed phpMyAdmin.

Copy the config.sample.inc.php in "/users/[User name]/sites/phpmyadmin/" and name it config.inc.php

Open config.inc.php and make the following changes:

Used for cookie encryption, random long strings

$cfg [' blowfish_secret '] = ';

When "#2002 cannot log on to MySQL server" appears in phpMyAdmin,

Please change the localhost to 127.0.0.1.

This is because the MySQL daemon did the IP binding (bind-address =127.0.0.1) caused by the

$cfg [' Servers '] [$i] [' host '] = ' localhost ';

Change false to True so that you can access MySQL without password,

This can be set even if MySQL has a password set, and then enter the password when you log in to phpMyAdmin

$cfg [' Servers '] [$i] [' allownopassword '] = false;

This allows the phpMyAdmin to be accessed through the http://localhost/~[user name]/phpmyadmin. At this point, I see a hint. "Unable to load the mcrypt extension, please check your PHP configuration. ", this involves installing the mcrypt extension in the next section.

Configuring PHP's MCrypt Extension

MCrypt is a powerful encryption algorithm extension library, which includes 22 algorithms, phpMyAdmin relies on this PHP extension library. But its installation under Mac OS X is less friendly, as follows:

Download and unzip the libmcrypt-2.5.8.tar.bz2.

Execute the following command at the terminal (note that the following commands are required to install Xcode support):

CD ~/downloads/libmcrypt-2.5.8/

./configure--disable-posix-threads--enable-static

Make

sudo make install

Download and unzip php source file php-5.3.1.tar.bz2. The PHP version preinstalled in Mac OS X 10.6.3 is 5.3.1, and now the latest PHP version is 5.3.2, you need to choose the appropriate version according to your actual situation.

Execute the following command at the terminal:

CD ~/downloads/php-5.3.1/ext/mcrypt

Phpize

./configure

Make

CD modules

sudo cp mcrypt.so/usr/lib/php/extensions/no-debug-non-zts-20090626/

Open php.ini

sudo vi/etc/php.ini

Add the following code to the php.ini, save and exit, then restart Apache

Extension=/usr/lib/php/extensions/no-debug-non-zts-20090626/mcrypt.so

When you revisit http://localhost/~[username]/phpmyadmin, you will find "unable to load the mcrypt extension, please check your PHP configuration." "The hint is gone, which means the MCrypt expansion Library was installed successfully.

Set up a virtual host

Run "sudo vi/etc/apache2/httpd.conf" on the terminal to open the Apche configuration file

Find "#Include/private/etc/apache2/extra/httpd-vhosts.conf" in httpd.conf, remove the "#" from the front and save and exit.

Run "sudo apachectl restart" and restart Apache to turn on its virtual host configuration feature.

Run "sudo vi/etc/apache2/extra/httpd-vhosts.conf" to open the file httpd-vhost.conf that configures the virtual host and configure the virtual host you need. It is important to note that the file is enabled by default for two virtual hosts as an example:

<virtualhost *:80>

ServerAdmin [email protected]

DocumentRoot "/usr/docs/dummy-host.example.com"

ServerName dummy-host.example.com

Errorlog "/private/var/log/apache2/dummy-host.example.com-error_log"

Customlog "/private/var/log/apache2/dummy-host.example.com-access_log" common

</VirtualHost>

<virtualhost *:80>

ServerAdmin [email protected]

DocumentRoot "/usr/docs/dummy-host2.example.com"

ServerName dummy-host2.example.com

Errorlog "/private/var/log/apache2/dummy-host2.example.com-error_log"

Customlog "/private/var/log/apache2/dummy-host2.example.com-access_log" common

</VirtualHost>

In fact, these two virtual hosts do not exist, and when no other virtual host is configured, it may result in the following prompt when accessing localhost:

Forbidden

You don't have permission to access/index.php on this server

The simplest way to do this is to add the # to the front of each line and comment it out, so that you can refer to it without causing other problems.

Add the following configuration

<virtualhost *:80>

DocumentRoot "/users/[User name]/sites"

ServerName Sites

Errorlog "/private/var/log/apache2/sites-error_log"

Customlog "/private/var/log/apache2/sites-access_log" common

</VirtualHost>

Save the exit and restart Apache.

Run "sudo vi/etc/hosts", open the Hosts configuration file, add "127.0.0.1 sites", so you can configure the completion sites virtual host, so you can use "http://sites" access, its content and "http:// localhost/~[user Name] "is exactly the same.

This is a configuration implemented using the native support of Mac OS X 10.6.3, or "Mac OS X Leopard: Configuring Apache, PHP, SQLite, MySQL, and PhpMyAdmin (i)" and "Mac OS X leop ARD: Configure Apache, PHP, SQLite, MySQL, and PhpMyAdmin (ii) ". In fact, you can also use XAMPP or MacPorts as a third-party integration solution for simple installation and use.
