ZH cheese: Ubuntu 14.04 configuration lamp (Linux, Apache, MySQL, PHP)

ZH cheese: Ubuntu 14.04 installation lamp (linux,apache,mysql,php) has been introduced before lamp installation, this article mainly explain the lamp configuration.

1. Configure Apache

(1) Adjust the KeepAlive settings (refer to [1], [2]):

On a server with sufficient memory, the server performance will not change significantly, whether or not the KeepAlive function is turned off;

If the server memory is low, or the server has a very large number of file system access, or the main processing Dynamic Web services, the shutdown KeepAlive can save a lot of memory, and the saved memory for the file system cache, can improve the performance of file system access, and the system is more stable.

Files:/etc/apache2/apache2.conf

KeepAlive OFF

(2) Configuring Multi-Processing Module (MPM) (reference [3])

Apache default MPM is event module,php using Prefork module.

Files:/etc/apache2/mods-available/mpm_prefork.conf

The configuration below is more suitable for 1GB Linode VPS

<ifmodule mpm_prefork_module>    startservers        2    minspareservers      6     maxspareservers         maxclients                 </IfModule>

(3) Deactivate the event module and enable the Prefork module

sudo A2dismod mpm_event sudo a2enmod mpm_prefork

(4) Restart Apache

sudo service apache2 restart

2. Configuring virtual Hosts

There are many ways to configure a virtual host, and below is the recommended method. By default, Apache listens for all IP addresses that can access it.

(1) in the directory /etc/apache2/sites-available/ directory, create a new profile for your site example.com.conf , replace it with your own domain name example.com

Files:/etc/apache2/sites-available/example.com.conf

<virtualhost *:>      ServerAdmin [email protected]     ServerName example.com     Serveralias www.example.com     /var/www/html/example.com/public_html/     /var/www/html/example.com/logs/ Error.log       /var/www/html/example.com/logs/access.log combined     <Directory/path/to/public/website/>         Require All granted     </Directory></VirtualHost>

Note: It is recommended that the errorlog and customlog entrances be as fine-grained as possible (detailed partitioning)

Attention! : If Errorlog and Customlog (for example, above) are configured, you must ensure that the path logs exists before restarting Apache.

(2) Create a directory:

sudo mkdir -p/var/www/html/example.com/public_htmlsudomkdir /var/www/html/example.com/logs

(3) Link your web hosting file from the Sites-available directory to the sites-enable directory:

sudo a2ensite example.com.conf

Note: If you later need to remove this site, run:

sudo a2dissite example.com.conf

(4) Reload Apache

sudo service apache2 Reload

3. Create a MySQL Database

(1) Login

(2) Create a database and an authorized user (for example, create a WebData database with the user name: webuser, Password: password):

CREATE database WebData; grant all on WebData. ' WebUser ' ' Password '

(3) Exit MySQL:

Quit

4. Configure PHP

(1) configuration file: /etc/php5/apache2/php.ini

Configure more error descriptions, logs, and performance.

error_reporting = e_compile_error| e_recoverable_error| e_error|  =/var/log/php/

Note: Make sure that the top lines are not commented out. Comment lines begin with a semicolon (;)

(2) Build a log directory for PHP and give Apache ownership:

sudo mkdir /var/log/phpsudochown www-data/var/log/php

(3) Reload Apache:

sudo service apache2 Reload

Summary: Now know the Apache and PHP configuration file location and methods, more understanding of configuration parameters, you can configure a more suitable site for their site.
