The scope of this tutorial is to present a classic installation of Ubuntu 1. Server made from a CD media or an USB bootable stick and also, a basic installation of LAMP (Linux, Apache, My. SQL and PHP) packages stack with basic configurations.
Step 1: Installing Ubuntu 1. Server. 1. Create a bootable CD/USB image. After system booting sequence choose your media bootable type from BIOS options ( CD/DVD or USB drive ). On the first prompt choose your Language end hit Enter. Select Language. 2.
On next screen choose Install Ubuntu Server and hit Enter. Install Ubuntu Server. Next select your System default Language and also Installation process Language. Choose Language. 4. If your country is nor listed in default Location options choose Other, select your Continent and then your Country.
Select Your Location. Select Continent. Select Country. 5.
Next select your locales, Try choosing a general one like UTF- 8 encoding so later you won’t have problems with keyboard.Select Locals. 6.On next prompt configure your Keyboard – again on servers you should choose a general keyboard Language. How To Install Solid Surface Vanity Top more.
Also in this stage the installer can automatically detect your keyboard Layout by pressing a series of keys so be advised to choose No and setup English as default language. Select Keyboard. Select Keyboard Language. Select Keyboard Layout. After some additional software components are loaded for the installation process to continue. DHCP server on your directly connected network the installer automatically configures network settings with ones provided from the DHCP server. Because a server offers public or private network services, the network setting (especially the IP address) must always be static configured. Loading Additional Components.
Configuring DHCP Network. If you get the same result on network hostname prompt press Tab key, choose Go Back and then Configure network manually.
Enter Hostname. Configure Network. On next prompt series enter your network interface settings: IP address, netmask, gateway and DNS name servers. Enter IP Address.
Enter Netmask. Enter Gateway. Enter Name Server. Setup your system hostname – you can also enter your FQDN. Be advised to choose your system hostname wisely and unique because some programs highly depend on this. Enter Network Hostname.
Now is time to setup your administrative user. On Ubuntu this user replaces the root account and has all root account powers by employing sudo. Enter your username and hit on Continue.
Enter Full Name. Enter User Name. Enter your password twice and for security reasons you should always choose a strong one on servers ( at least 1. Enter Password. Re- enter Password.
In case you used a weak password the installer will alert you. If you are on a test server then choose Yes and continue further. Password Verification. If your server contains sensitive, secret or important data on Users home partition the next screen offers the option to secure all data by Encrypting home directory. If this is not the case choose No and hit Enter.
Encrypt Home Directory. If while installer runs and your network interface card has Internet connectivity the installer will automatically detect your Location and setup your correct time zone. If the provided time is not correctly setup you have the option to choose it manually from a list else choose Yes and press Enter.
Configure Time Zone. The hard- disks Partition table is one of the most sensitive subjects involving a server because here you have a lot of tweaking to do depending on your server final destination type web server, databases, file sharing NFS, Samba, application server etc. For example if redundancy, fail- over and high- availability is needed you can setup RAID 1, if your space grows fast you can setup RAID 0 and LVM and so on. For a more general use you can just use the Guided option with LVM, which is a customized option made by developers.
For a production environment you probably should have LVM, software or hardware RAID and separate partitions for /(root), /home, /boot and /var ( the /var partition has the most fast growing rate on a production server because here are logs, databeses, applications meta info, servers caches and others located. So on Partition Disks choose Guided –user entire disk and set up LVM - > select your disk to partition and accept partition table. Partition Disks. Select Disk Partition.
Write Changes to Disks. After the partition table has been written to disk the installer once again prompts you with a partition review. Accept the Partition Table and hit Yes. Confirm Write Changes to Disks. If you like to make some changes to this Partition Table you can select No and edit your partitions. Partition Overview.
After all hard- disk partitions had been written to disk the installer starts copying data software to disk and then reaches HTTP proxy option. If you don’t access Internet through a proxy leave it blank and Continue. Installing System. Configure Package Manager. Next the installer scans the CD image for software packages and reaches Updates options.
Choose No automatic updates because on servers you should try manual update the system. Configure Apt. Configure Tasksel. Now the base system is installed but the installer invokes tasksel package which helps you to install some server packs before finishing. For a better control over your server choose only Open. SSH server by pressing Space bar key while others will be installed and configured later and choose Continue. Software Selection. The selected packages are being installed while the last option is displayed on your monitor demanding to Install GRUB to MRB.
Because the system can’t boot on his self without GRUB, choose Yes. Install GRUB2. 1. Once the GRUB boot loader is installed the installation process reaches it’s end. Remove your media installation drive (CD/DVD,UDB) and hit Continue to reboot. Finish Installation. GRUB Boot Menu. Congratulations! Ubuntu 1. 4. 0. 4 LTS Server edition is now installed and ready to rock on your brand new metal or virtual machine.
Step 2: Basic Network Configurations. For now only the Core server packages are installed and you can’t really offer network services for your network. In order to install software login to your server console for now and verify some basic configurations like network connectivity, settings, startup daemons, software sources, updates and others by running a series of Linux commands. View system load and basic information – After login with your credentials this information is presented by default MOTD. Also top and htop commands are useful. Login Screen. 23.
Verify network IP addresses using following command.# ifconfig –a. Verify IP Address. Verify internet connectivity: run ping command against a domain name ( this will test TCP/IP stack and DNS ).# ping –c 4 google. If you get “unknown host“ message, edit your ‘/etc/resolv. IPAdd Name Servers.
Confirm Name Servers. For permanent changes edit ‘/etc/network/interfaces‘ file and add dns- nameserver directive. Add Network Details.
Verify machine hostname using following command.# cat /etc/hostname. Verify Hostname. 26.
Software platform virtualization in chemistry research and university teaching. Application of VMs in research and system benchmarks. The micro benchmarks were performed to validate the use under heavy computational tasks. The benchmark programs were selected according to frequent use in cheminformatics and mass spectrometry laboratories. The Microsoft Virtual PC only utilizes one single CPU. Therefore all results are based on single CPU speed instead of utilizing the dual core capabilities. The MS Server version and VMWare virtual machine also allow multiple CPU setups but were not used for comparison.
The fastest mode in a virtual machine is the direct execution mode [3. Certain CPU specific commands are prevented from running within the virtual machine or they generate a CPU exception and therefore the virtual machine is needed to emulate such a machine code via binary translation and is much slower. That also explains the very small CPU based speed penalty (virtual machine overhead) for running programs inside the virtual machine. The start time of a freshly installed virtual machine is usually faster than that of an aged system, because no additional drivers and programs are installed. As seen in Table 2 the start time of the guest OS is only 5. OS. A minimum install of Windows XP usually boots in 3. The minimum memory requirements are quite astounding with 1.
MBytes but the real- time antivirus software needs an additional 5. MBytes. In comparison a 3 year old production system needs 7. MByte, with additional restrictions that 3. Windows systems can only allocate and use 2. GBytes even if more memory is installed.
The problem is that many programs and hardware driver software for mass spectrometers are not yet certified for 6. One solution here is to install a large memory system with a 6. OS and use the 3.
OS, allowing both 3. Windows 6. 4- bit can directly emulate 3. If, however, 6. 4- bit drivers are required and not yet available the program can not be installed in the first place. Discussion of cheminformatics and mass spectrometry related benchmarks. The single core benchmarks NIST Sci. Mark 2. 0a, Molgen Demo, CDK Descriptor GUI, Seven Golden Rules are all single- threaded benchmarks. Table 2 shows that the speed penalty within the virtual machine is around 5- 1.
No investigation of the impact of disk speed was performed.But the fast Areca RAID- 6 system allows full guest CPU utilization.Therefore the penalty on disk use exists but is very small on a hardware RAID system. on this page. In case of a slow single hard disk on the host system, the disk performance within the guest system is also lower.In such a case the disk system overhead from guest and host system add up and decrease the overall disk speed.
Many new desktop computer systems utilize minimum two CPUs. The new Intel Nehalem Core i. CPUs each with a total of eight working threads. Unfortunately only few chemistry and mass spectrometry desktop applications are multi- threaded or multi- core ready [3. Among the tested versions which can make use of multi- core systems are the JChem calculational routines and MZMine. The speed penalty on single- threaded programs compared to a dual core setup is severe.
The stereoisomer calculation shows that on a dual processor machine a doubled performance can be obtained. Unfortunately, the Microsoft Virtual PC is a single- threaded application and does not allow the use of multi- core CPUs in the guest virtual environment. Ironically, when Microsoft bought the Virtual PC technology from Connectix in 2. SMP) virtual machines.
The free Microsoft Virtual PC 2. Microsoft Virtual Server 2 is marketed as a server product and can utilize multi- core CPUs. In comparison, the commercial VMWare Workstation and the open source Virtual. Box both support virtual symmetric multiprocessing (SMP) and currently up to 3. CPUs can be used in the guest system. The MZMine. 2 test especially shows the disk I/O dependence because of the large file size and the multi- core CPU dependence, because the software can be executed according to the number of available threads on the computer and therefore performs with double speed on a dual CPU setup.
Virtual machines can diversify operating system choices in chemistry labs. The majority of software that is commercially sold together with mass spectrometers is running under Microsoft Windows. One reason may be the sole availability of Microsoft Windows driver software for analog- digital converters (AD/DA) which are required when connecting mass spectrometers to PCs. However there is no explanation why LINUX installations cannot be used because many older instruments were successfully running under different UNIX operating systems. The reason of developing vendor software only for a single operating system is based on the complexity of the software development tools and the development and support costs. Aiming at a single platform certainly reduces costs for the vendor. Hardware near programming furthermore usually requires C or C++ code development.
The data evaluation part can be done on multiple platforms including Linux, Mac OS and Windows. Here cross- platform applications written in JAVA, which have the ability of running on many different operating systems have a clear advantage. Modern mass spectrometry labs usually use multiple operating systems for historic reasons.
Windows computers are used for operating chromatography equipment and mass spectrometers, LINUX OS for running software on computer clusters and Mac OS X for personal workstations and laptops. However only very few mass spectrometry desktop applications are available for Mac. OS [3. 8]. That problem can be solved by using a virtual PC application like VMware Fusion or Parallels Desktop for MAC to install Windows compatible applications. As already mentioned it is currently prohibited by Apple Inc. Mac OS X as a guest operating system in a virtual machine on non- native apple hardware. The choice between 3.
If the computer has more than 4 GByte RAM available and the motherboard and CPU are 6. GByte memory. In case of less than 4 GByte RAM a 3. The other major obstacle is the availability of programs and drivers that are natively compiled for 6.
If such 6. 4- bit software drivers are not available for hardware cards (AD/DA converters, PCI cards) then it is impossible to use that hardware on a 6. In case of 3. 2- bit software this is not a major problem, because most 6. It is recommended however to test all system critical software on a virtual machine before deploying them in a working environment. Hardware choices for software virtualization in chemistry labs. For server consolidation purposes usually server- grade components are used. That includes a motherboard capable of multi- socket CPU setups and enough memory banks to handle memory from 3. GByte RAM. As CPUs the quad- core or hex- core Intel XEON (based on Nehalem technology) as well as AMD Opteron (based on Shanghai or Istanbul 4.
The overall hard disk performance is extremely important for virtualization, therefore a series of 1. SAS or SATA hard drives using RAID6 or RAID1. RAID controllers (such as ARECA, LSI, ADAPTEC, 3. WARE) should be used. A native hypervisor virtual machine monitor (XEN, VMware ESX Server or Microsoft Hyper- V) can be installed as core software layer. Any LINUX or WINDOWS guest operating system can be installed into the hypervisor. For desktop virtualization a dual- core or quad- core processor (Intel Core i.
AMD Phenom) should be used. The memory can range from 2 to 3. GByte. As operating system any 6. LINUX, MAC or WINDOWS system can be installed. For each virtual machine a minimum of 8. MByte RAM should be considered. Therefore if the host operating system uses 1 GByte RAM and it is planned to run four virtual machines in parallel, a minimum of 4 GByte RAM is needed.
As hard disk system an Intel Matrix software RAID with multiple disks can be used. For even higher performance a Solid State Disk (SSD) setup or server grade hard disks with an ARECA RAID controller are recommended. Currently only limited support for Direct. D graphics cards and other specialized hardware inside virtual machines are provided. Applications that require such hardware should be run on native systems. Figure 5 shows an Intel Nehalem 3 GHz quad- core system equipped with four hard disks in RAID1.
The system can be used to virtualize special hardware, like a 3. LINUX machine as seen in the screenshot. The high average hard disk transfer rate of around 2.
