Ubuntu Server + openerp (2)

Set Host Name
After the network is set, the installer requires you to set the computer name. The name should be the same as the first line of the computer website. If the website is esmail.example.org, the host name should be esmail. (The host name can only consist of letters, numbers, and minus signs)

Time Zone
The installer will automatically determine your time zone based on the region you have previously set, and ask you to confirm:

However, if your region has too many time zones (such as the United States), the installer will list all the time zones in the region, so that you can select the correct time zone:

Split hard disk and Format hard disk
Next we came to the most difficult and error-prone part of the entire GNU/Linux installation process-split the hard disk. To install two or more operating systems on the same hard disk and facilitate the management of different types of data, we must divide the hard disk into multiple partitions ). This is just as if two or more guests are in the same house, the house owner also needs a room. Even if there is only one guest, there will be a study, bedroom, dining room and kitchen.
The difficulty of this work is that most personal computers are pre-installed with other operating systems (most of which are Microsoft Windows), and the entire hard disk space is allocated with pre-installed operating systems early in the morning. Many non-technical personnel have no idea about splitting hard disks, and sometimes damage their original operating system and the information in it without knowing it. However, you only need to be careful when dealing with it. Generally, there is no problem.

However, the server rarely has two or more operating systems installed on the same computer, so splitting the hard disk is much easier than working on the desktop.

Ubuntu provides several solutions to split hard disks:
1) use the entire disk (use entrie disk)-This solution will delete all partitions on the hard disk and then split the hard disk again. If you have another operating system on your hard disk that you want to retain, do not select this option.
2) use the entire disk and use LVM (use entrie disk and use LVM)-This solution will delete all partitions on the hard disk and then use LVM to separate the hard disk. If you have another operating system on your hard disk that you want to retain, do not select this option.
3) use the largest continuous unused space (use the largest continuous free space)-If your hard disk has enough unused space, you will see this solution. This solution will find the longest consecutive vacancies on the hard disk and install Ubuntu on the vacant space.

4) Manual-this solution does not automatically split the hard disk. It only allows you to manually split the hard disk.
The method to use this solution is as follows:
1) if the information on the hard disk is completely useless, and you decide to allocate the entire hard disk to Ubuntu, please Use the entire disk (Use entrie disk ).
2) If the information on the hard disk is still useful, but there is enough space (not less than 3 GB ), use the largest continuous free space ).
3) when none of the above conditions is suitable for you, you can manually separate the hard disk. Pay attention to the risks of using this method.
After selecting the solution, the installer will list all your hard disks and ask you to separate them:

Once again, you are reminded that once all the preceding splitting schemes are executed, you cannot cancel or reply to them. If the hard disk still has information to be retained, do not use Erase entrie disk ).

Click "Yes" (Yes) to confirm that you want to split the disk in the selected disk.
After selecting the appropriate solution and hard disk, the installer will naturally compile the Splitting Method for you and draw out the method for your final confirmation:

If there is no problem, press "Yes" (Yes.
Install the basic system

User Information and password
GNU/Linux and Unix are Multi-User operating systems. a gnu/Linux operating system can be used by multiple users at the same time. To facilitate the management of each user's files and resources, each user has his/her own user account and password ). Ubuntu requires you to create a user account first, so you will see the following picture asking you to enter the information and password of the first user of the new Ubuntu:

First, enter your name (yourname ). This is mainly used as the direct real name on applications such as emails. Except for the colon (:) and comma (,), the name can be composed of any character with spaces in the middle. It is best to use English.

Then, enter the user name (name use to log in), which is the name used for login. It can only consist of English letters, numbers, hyphens (-), and hyphens, you cannot enter an empty space or the first character must be an English letter. Note that the usernames of Unix/Linux are case-sensitive, that is, jrandom, JRANDOM, and JRandom are three different users. To avoid confusion, we recommend that you use all lowercase letters as the user name.

Enter the password required for logon, which is also case sensitive. To reduce the chance of being cracked, do not use the phone number, birthday date, person name, or any word found in the dictionary as a password.

Install software
If you have a Proxy, you can set it here to reduce the download time:

Next, you need to set the update scheme:

Currently, the Ubuntu server provides three update solutions:
No automatic update)
Install security updates automatically)
Manage system with Landscape)
Select the software package to install:

At present, the Ubuntu server version provides nine software combinations:
DNS server-Domain Name server
LAMP server-a combination of Linux + Apache + MySQL + PHP. It uses Apache as the Web server, MySQL as the database management system, and PHP as the website application language. It can set up a website or e-commerce system.
Mail server-email server, using Postfix as MTA and Dovecot as POP and IMAP servers.
OpenSSH server-remote access server
PostgreSQL server-database server, using PostgreSQL
Print server-Print server, using CUPS
Samba server-use Samba as an archive server that can be integrated into Windows networks
Tomcat Java server-use Tomcat's Java Web Application server
Virtual Machine host-Virtual Machine Server
Manual package selection-manually select the package to be installed from thousands of suites.
After selecting the software combination, start to install the software by pressing "Continue:

The following figure indicates that you have successfully installed the Ubuntu server.

Now you can press "Continue" to restart the Ubuntu server.
