PLESK 6.0 ADMINISTRATOR MANUAL > Preparing To Install Plesk 6.0 > What Happens During Installation?

Installing Plesk on FreeBSD 4.7 server

The Plesk Self-Extracting install includes the following components:

  • Admin server
  • Web server
  • MySQL database
  • PostgreSQL database
  • Mail server
  • Mailman
  • DNS server
  • FTP server
  • Tomcat
  • JDK

The following services will be controllable under Plesk:

  • named - BIND 9.2.2
  • MySQL - 3.23.56
  • Qmail - 1.03
  • courier-imap - 1.7.3
  • Apache - 1.3.27
  • ProFTPD - 1.2.7
  • stunnel - 4.04
  • Tomcat - 4.1.24
  • PostgreSQL - 7.2.4
  • Mailman - 2.0.13

NOTE

Additional services controllable under Apache are mod_throttle 3.1.2, mod_perl 1.27, mod_python 2.7.8, mod_ssl 2.8.14, PHP 4.3.1, apache::asp 2.49, Front Page 2000 and Front Page 2002.

Directory Structure

Plesk creates the directory /usr/local/psa/ as its root software directory. The location of this directory is defined and changeable within the /etc/psa/psa.conf file.

Accounts and Groups

Plesk creates accounts for Plesk administrator, anonymous FTP user, Apache, MySQL, Mailman and qmail pseudo-users and Tomcat and PostgreSQL users. These pseudo-users do not have shells in which to operate, alleviating security concerns involving the users.

Services

The following changes in services take place:

  • Plesk disables the sendmail service and replaces it with qmail.
  • Plesk replaces your named database and configuration files. Then Plesk restarts the named daemon.
  • Plesk also edits the inetd/xinetd configuration file and comments out the comsat service record.
  • Plesk adds the FTP service, using ProFTPD to handle it. If you had a previous FTP service on the server, Plesk comments out the old version and uses the new FTP version.
  • Plesk adds a SMTP service record, handled by the qmail daemon. If you had a previous SMTP service record, Plesk comments it out and replaces it with the new version.
  • The inetd/xinetd daemon is restarted to read its new configuration file.

Using an external DNS server

You can use an external DNS service with Plesk, but you should follow these manual configuration steps:

  1. During operating system installation, a remote DNS server can be specified. Or after installation, the remote DNS can be specified in the /etc/resolv.conf file.

  2. The line search localdomain must be removed from the /etc/resolv.conf file on the Plesk server.

  3. Any DNS configurations on the local Plesk server must be reflected on the external DNS server.

Other Changes

Plesk creates some links to the MySQL libraries in the /usr/lib subdirectory and adds the @psacln string to /etc/ftpchroot. Also, it adds a string to the file /etc/shells:

  • /bin/false, or
  • /usr/bin/false

If the POP3 service record is not in /etc/services, Plesk adds it. Plesk moves the sendmail binary file to sendmail.plesk. The Plesk startup script is placed in the appropriate location to start Plesk; this script will enable Plesk to start each time the server is booted up.
