Haas PhD Server Configuration

Haas PhD Students have two new servers and this page details their configuration.

IP Addresses

During the configuration phase the servers will be on:

• phd-pgsql: 128.32.66.163
• phd-lamp: 128.32.66.164

Base configurations

Both servers are running CentOS release 5.5 (cat /etc/*release*), which uses the Yum package manager (yum list installed | more). Both have Gnome on Xwindows available, as well as the following common packages:

• cpp 4.1.2-48.el5.
• ftp 0.17-35.el5
• httpd 2.2.3-43.el5.centos.3
• iptables 1.3.5-5.3.el5_4.1
• mysql 5.0.77-4.el5_5.4
• openssh 4.3p2-41.el5_5.1
• pam 0.99.6.2-6.el5_5.2
• perl 4:5.8.8-32.el5_5.2
• python 2.4.3-27.el5_5.3
• php 5.1.6-27.el5_5.3
• samba 3.0.33-3.29.el5_5.1
• squid 7:2.6.STABLE21-6.el5

Notable additional packages on pgsql are:

• postgresql.x86_64 8.1.22-1.el5_5.1

Package additions/upgrades/removals

On lamp:

• Upgrade python to version 3.1
• Install mediawiki
• Remove ftp

On pgsql:

• Remove httpd, mysql, ftp

Configuration

For both servers:

• Mount bear
• Configure Iptables

For lamp:

• Configure Apache
• Configure Mediawiki
• Add Mediawiki extensions
• Create new folder structure

For pgsql:

• Configure Postgre

Mounting bear

mount -t cifs //bear/ed_egan/ /mnt -o user=ed_egan

for the inclusion into fstab or other more sophisticated approaches there is a Centos help page.

Configure Apache

To start Apache: /etc/init.d/httpd start

To set Apache to start at boot: chkconfig --levels 235 httpd on

The main config file is: /etc/httpd/conf/httpd.conf

First, confirm your IP address: /sbin/ifconfig

Configure IpTables

For lamp we need a hole for port 80 for the webserver. For pgsql we need a hole for our clientware. General documentation is available in iptables from Centos

Check that iptables is running: /sbin/lsmod | grep ip_tables

View the rules either by: cat /etc/sysconfig/iptables /sub/iptables -L

Backup the old rules: cp /etc/sysconfig/iptables /etc/sysconfig/iptables.bak

Add a hole (or two):

/sbin/iptables -A INPUT -s 128.32.74.0/24 -p tcp --dport 80 -j ACCEPT

Save the table (so it will persist post a reboot): /sbin/service iptables save

Data

For lamp:

• Import Wiki pages
• Change links to pdfs and repository files
