Cp support-files/mysql. server/etc/init. d/mysqld

Chmod 755/etc/init. d/mysqld
Vim/etc/init. d/mysqld # modify datadir
Chkconfig -- add mysqld
Chkconfig mysqld on
Service mysqld start

 

 

2. install apache
Wget http://syslab.comsenz.com/downloads/linux/httpd-2.2.16.tar.gz
Tar zvxf httpd-2.2.16.tar.gz
Cd httpd-2.2.16
./Configure -- prefix =/usr/local/apache2 -- enable-mod-shared = most -- enable-so
Make & make install

Use: cat/usr/local/apache2/build/config. nice: You can view the compilation parameters.

./Bin/apachectl graceful: Do not kill the process.

 

3. install php
Wget http://cn2.php.net/distributions/php-5.3.28.tar.gz
Tar zxf php-5.3.28.tar.gz
Cd php-5.3.28
. /Configure -- prefix =/usr/local/php -- with-apxs2 =/usr/local/apache2/bin/apxs -- with-config-file-path =/usr/local/php/ etc -- with-mysql =/usr/local/mysql -- with-libxml-dir -- with-gd -- with-jpeg-dir -- with-png-dir -- with-freetype-dir -- with-iconv-dir -- with-zlib-dir -- with-bz2 -- with-openssl -- with-mcrypt -- enable-soap -- enable-gd-native-ttf -- enable-mbstring -- enable -sockets -- enable-exif -- disable-ipv6

(Apxs is automatically configured for php)
Make & make install

Check which modules are installed:

/Usr/local/php/bin/php-m

/Usr/local/php/bin/php-I: Check the php parameters.

 

 

4. Configure apache with php
Vim/usr/local/apache2/conf/httpd. conf
Find:
AddType application/x-gzip. gz. tgz
Add below this row:
AddType application/x-httpd-php. php

Check:/usr/local/apache2/bin/apachectl-t

Find:

DirectoryIndex index.html

Change this row:

DirectoryIndex index.html index.htm index. php

Find:
# ServerName www.example.com: 80
To:
ServerName localhost: 80

 

 

5. Test parsing php
Vim/usr/local/apache2/htdocs/1.php
Write:

Phpinfo ();
?>
Save and continue the test:

Curl localhost/1.php

 

 

If the PHP file cannot be parsed:

Check if apache has loaded php:

Ls/usr/local/apache2/modules/libphp5.so

Ldd: Check whether the load is successful.

Check whether php has been loaded successfully:

Grep-I 'addtype'/usr/local/apche2/conf/httpd. conf

Restart apache and try again.

 

Test the connectivity of mysql:

Write a file and access it. The file content is as follows:

$ Conn = mysql_connect ("localhost", "root ","Password");

If ($ conn ){

Echo "mysql connection successful! ";

}

Else {

Echo "failed to connect to mysql! ";

}

?>

If "mysql is successfully connected" is output! "The connection is successful!
