Needs some help with ubuntu slice

Hi,

I need help installing software on my ubuntu slice.

I need to install apache2, php and mysql.

Also, if possible, postfix, dovecot and squirrelmail.

Can someone please guide me through installing these securely?

There are many tutorials, but none provide a universal step by step guide, all are shortcuts to getting things going without considering security.

Help is appreciated

Cheers

 

I am concerned how secure the various tutorials on installing stuff on your ubuntu distribution really are.

Here is what I have done so far:

# make sure that dapper universe is not commented in source.list
# and make sure the ubuntu dapper is up to date
sudo perl -pi -e 's/#\s?(.*dapper universe$)/\1/g' /etc/apt/sources.list
sudo apt-get update && sudo apt-get upgrade

# install mysql
apt-get install mysql-server mysql-client libmysqlclient12-dev

# edit /etc/mysql/my.cnf and comment out the line bind-address = 127.0.0.1:
# then restart mysql
/etc/init.d/mysql restart

# then change root password
$ mysql -u root
mysql> UPDATE mysql.user SET Password=PASSWORD ('your_root_mysql_password') WHERE User = 'root';
mysql> FLUSH PRIVILEGES;
mysql> quit

# install apache2
apt-get install apache2 apache2-common apache2-doc apache2-mpm-prefork apache2-utils libapr0 libexpat1 ssl-cert

# install php
apt-get install autoconf automake1.4 autotools-dev libapache2-mod-php5 php5 php5-common php5-curl php5-dev php5-gd php-pear php5-ldap php5-mhash php5-mysql php5-mysqli php5-snmp php5-sqlite php5-xmlrpc php5-xsl php5-imap php5-mcrypt php5-pspell

# edit apache2.conf
nano /etc/apache2/apache2.conf

# change DirectoryIndex to
DirectoryIndex index.html index.htm index.shtml index.cgi index.php index.php3 index.pl index.xhtml

# enable apache modules
a2enmod ssl
a2enmod rewrite
a2enmod suexec
a2enmod include

# reload apache config
/etc/init.d/apache2 force-reload

I then make sure my domain is setup with apache at the following places:
/var/www/my_domain.com
/var/log/apache2/my_domain.com
/etc/apache2/sites-available/my_domain.com

my_domain.com virtual host file contains the following:

<VirtualHost *>
ServerName www.my_domain.com
ServerAlias my_domain.com
DocumentRoot /var/www/my_domain.com

CustomLog /var/log/apache2/my_domain.com/access.log combined
ErrorLog /var/log/apache2/my_domain.com/error.log

<Directory "/var/www/my_domain.com">
Options None
AllowOverride None
Order allow,deny
Allow from all
</Directory>

</VirtualHost>

#simlink my new domain to sites-enabled directory
ln -s /etc/apache2/sites-available/my_domain.com /etc/apache2/sites-enabled/my_domain.com

# edit Apache’s configuration file to tell it my IP address:
vi /etc/apache2/apache2.conf
# paste this before the # Include the virtual host configurations: line (it’s one before the last):
ServerName my.slice.ip.address

# edit Apache’s log rotation to include my new domain:
vi /etc/logrotate.d/apache2

# paste this at the end:

/var/log/apache2/my_domain.com/*.log {
weekly
missingok
rotate 52
compress
delaycompress
notifempty
create 640 root adm
sharedscripts
postrotate
if [ -f /var/run/apache2.pid ]; then
/etc/init.d/apache2 restart > /dev/null
fi
endscript
}

I am stuck on what to do next to finish my installation.

Can someone please take the time to check the above detail and also let me know what else I need to know?

I have tried various links and tutorials, but all lack detail.
