1577 Serverteknologi - Web-server Opgaver II

2009-08-25T08:50:27Z

Alba:

<center>'''Øv 2: Installation af fil-servere'''</center>

Begynd med at installere WebMin ( [http://www.webmin.com/ http://www.webmin.com/] ).

Forestil jer en organisation ( f.eks. et firma, som fremstiller et eller andet og som har et antal ansatte ( brugere ).

Nogle af de ansatte bruger pc'er med Win XP, andre bruger Linux ( f.eks Ubuntu ).

Firmaet har alllerede en web-server ( den, I satte op i opg.1 ). Direktøren er uhyre tilfreds med det arbejde I har leveret hidtil og vil nu gerne have installeret:

# En fil-server til Windows brugerne ( Samba )
# En fil-server til Linux brugerne ( NFS ).
# En directory-server ( LDAP ). 

''samt:''

# En navne-server ( BIND ), så de ansatte slipper for at huske ip-adresser og port-numre på de forskellige servere.

<center>'''Øv 1: Installation af LAMP (Linux-Apache-MySql-Php)'''</center>

Begynd med at installere den tekst-baserede browser ’Lynx’:

<nowiki># yum install lynx</nowiki>

== 1.1.1 Installation af Apache web-server ==
Installér:

'''<nowiki># yum install httpd </nowiki>'''

( eller '''<nowiki># yum install httpd –y</nowiki>''', for automatisk at svare ’yes’ til alle spørgsmål under installationen).

''Start Apache (httpd):'''''<nowiki># /etc/init.d/httpd </nowiki>start'''

''Stop Apache (httpd):'''''<nowiki># /etc/init.d/httpd </nowiki>stop'''

''Genstart Apache (httpd):'''''<nowiki># /etc/init.d/httpd </nowiki>restart'''

Automatisk start ved boot:

'''<nowiki># chkconfig httpd on </nowiki>'''

( eller '''<nowiki># chkconfig --levels 235 httpd on </nowiki>'''. ’--levels’ angiver hvilke runtime levels, kommandoen skal gælde for ).

Konfigurations-fil til Apache web-serveren: /'''etc/httpd/conf/httpd.conf'''

Brug vi til at rette i konfigurations-filen: '''<nowiki># vi </nowiki>'''/'''etc/httpd/conf/httpd.conf'''

ServerName www.example.com:80 rettes til:

ServerName 192.168.0.xxx:80 ( Maskines ip-adresse – evt. 127.0.0.1 ).

(for at undgå: Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name,using 127.0.0.1 for ServerName)

== Test af Apache web-server ==
<nowiki># lynx localhost</nowiki>

Brug vi til at oprette en ny fil: index.html i biblioteket: /var/www/html

<nowiki>#vi /var/www/html/index.html og med flgd. indhold</nowiki>

<html>

<head>

<title>Apache test</title>

</head>

<body>

Apache virker!

</body>

</html>

og prøv igen med lynx: <nowiki># lynx localhost</nowiki>

eller: # lynx 127.0.0.1

== 1.2.1 Installation af MySql ==
'''<nowiki># yum install php-mysql mysql mysql-server</nowiki>'''<nowiki># </nowiki>'''chkconfig --levels 235 mysqld on'''<nowiki># </nowiki>'''/etc/init.d/mysqld start'''

'''<nowiki># </nowiki>'''mysqladmin -u root password yourrootsqlpassword

== 1.2.2 Test af MySql ==
<nowiki># </nowiki>'''mysql -u root –p'''

'''<nowiki># exit </nowiki>'''(''' '''for''' '''at''' '''afslutte''' ''')''' '''

== 1.3.1 Installation af PHP ==
<nowiki># yum install php*</nowiki>

<nowiki># /etc/init.d/httpd </nowiki>restart

== 1.3.2 Test af PHP ==
Brug vi til at oprette en ny fil: test.php i biblioteket: /var/www/html

'''<nowiki># </nowiki>vi /var/www/html/test.php '''og med flgd. indhold:

<nowiki><?php</nowiki>

print(phpinfo());

?>

'''<nowiki># Lynx localhost/test.php</nowiki>'''

== 1.4.1 Test af MySql + PHP ==
Brug vi til at oprette en ny fil: mysql.php i biblioteket: /var/www/html

'''<nowiki># </nowiki>vi /var/www/html/mysql.php '''og med flgd. indhold:

<nowiki><?php</nowiki>

$link = mysql_connect('localhost', 'root', 'mtpolice');

if (!$link) { die('Could not connect: ' . mysql_error()); }

echo 'Connected successfully';

mysql_close($link);

?>

'''<nowiki># Lynx localhost/mysql.php</nowiki>'''
