The most basic type of ssh connection is a remote login.最基本的類型的ssh連接是一個遠程登錄。 This will give you a command prompt on the remote computer, as if you had just sat down in front of it and opened GNOME Terminal.這會給你一個命令提示符在遠程計算機上,因為如果你剛剛坐下來在前面的,並開放GNOME的終端。 But before you can log in to any machine via ssh, you’ll need to be sure the remote computer is able to accept ssh connections.但在此之前就可以登錄到任何機器通過SSH ,您需要確保遠程計算機可以接受的SSH連接。 This means that it needs to be running the ssh server program (referred to as a service), and also that its firewall has an open port for incoming connections.這意味著,它需要運行SSH服務器程序(稱為服務) ,而且其防火牆已開放的端口傳入的連接。
The two major components of OpenSSH are the client and server.這兩個主要組成部分是OpenSSH客戶端和服務器。 Most distributions install both items and run the server component all the time.大多數分佈安裝這兩個項目並運行服務器組件的所有時間。 However, only the client component of SSH is installed under Ubuntu.然而,只有客戶端組件的SSH是安裝在Ubuntu Linux系統。 To install the server component, and therefore access your Ubuntu system remotely, you’ll need to open Synaptic Package Manager (System -> Administration) and search for openssh-server.要安裝服務器組件,因此,訪問您的遠程Ubuntu的系統,您需要打開突觸包管理器(系統-> “行政)和搜索o penssh服務器。 Click to install it.點擊進行安裝。 Configuration will be automatic, although if you’re using the Ubuntu firewall, you will need to configure an incoming rule to open port 22.配置將是自動的,但如果您使用的是Ubuntu的防火牆,您將需要配置一個傳入的規則,以打開端口22 。

After using Ubuntu for some time, you might find that the disk begins to get full.在使用Ubuntu的一段時間,您可能會發現磁盤開始得到充分。 You can keep an eye on disk usage by using the following command in a terminal window:您可以密切關注磁盤的使用使用下列命令在一個終端窗口:
df -h東風小時
This will show the free space in terms of megabytes or gigabytes for each partition, also expressed as a percentage figure.這會顯示可用空間方面的MB或容量為每個分區,也以百分比表示的數字。 If the disk does start to get full, you can take steps to make more space available.如果磁盤並開始得到充分,您可以採取步驟,使更多的可用空間。
Emptying the /tmp Folder 清空/ tmp的文件夾
An easy way to regain disk space is to empty the /tmp folder.一種簡單的方法來恢復磁盤空間是空的/ tmp的文件夾。 Like its counterpart in the Windows operating system, this is the folder in which temporary data is stored.像其對應的Windows操作系統,這是文件夾中的臨時數據存儲。 Some applications clean up after themselves, but others don’t, leaving behind many megabytes of detritus.一些應用程序後,清理本身,而是別人不,留下許多兆的碎屑。
Because the /tmp folder is accessed practically every second the system is up and running, to empty it safely, it’s necessary to switch to run level 1.由於/ tmp的文件夾是幾乎每一個進入第二個系統的投入運行,它空安全,有必要切換到運行級別1 。 This ensures few other programs are running, and avoids the risk of deleting data that is in use.這可以確保其他一些正在運行的程序,避免了風險,刪除數據,在使用中。 First, switch to the text console by pressing Ctrl+Alt+F1.首先,切換到文本控制台按按Ctrl + Alt +車隊。 Then enter these commands to switch to run level 1:然後輸入這些命令切換到運行級別1 :
sudo killall gdm須藤killall妊娠糖尿病

A lot of Ubuntu software relies on other pieces of code to work.許多Ubuntu的軟件依賴於其它的代碼工作。 These are sometimes referred to as libraries, which is a good indicator of their purpose: to provide functions that programs can check in and out whenever they need them, as if they were borrowing books from a library.這些有時被稱為圖書館,這是一個很好的指標,其宗旨:提供職能,程序可以檢查進出時,他們需要,因為如果他們借款的書籍圖書館。
Whenever a program starts, it must look for these other libraries and load them into memory, so they’re ready for use.每當一個程序啟動時,它必須尋找其他的圖書館和載入到內存中,所以他們已經準備好使用。 This can take some time, particularly with larger and more complicated programs.這可能需要一些時間,特別是與更大和更複雜的程序。 Because of this, the concept of prelinking was invented.正因為如此, prelinking概念的發明。 By a series of complicated tricks, the prelink program makes each bit of software you might run aware of the libraries it needs, so that memory can be better allocated.通過一系列複雜的技巧,在prelink計劃使每比特的軟件你可能會認識到它需要圖書館,使內存可以更好地分配。
Prelinking claims to boost program startup times by up to 50% or more, but the problem is that it’sa hack—a programming trick designed to make your system work in a nonstandard way. Prelinking要求提高計劃啟動時間達50 %或更多,但問題是,這是黑客,編程技巧,旨在使您的系統工作在非標準方式。 Because of this, some programs are incompatible with prelinking.正因為如此,某些程序不符合prelinking 。 In fact, some might simply refuse to work unless prelinking is deactivated.事實上,有些可能只是拒絕工作,除非prelinking被停用。 At the time of this writing, such programs are in the minority.在編寫本文件時,這些項目都在少數。 However, keep in mind that prelinking can be easily...但是,記住, prelinking可以很容易地...

Kickstart is a method for providing a predetermined installation configuration for installing Ubuntu.穩健是一種方法,提供了一個預先安裝配置安裝Ubuntu Linux系統。 Instead of having a user enter responses on the install screens, the responses can be listed in a kickstart file from which the install process can read.而不是用戶輸入響應的安裝屏幕,答复可以列在穩健的文件從安裝過程可以閱讀。 You will need to create a kickstart configuration file on a working Ubuntu system.您將需要建立一個穩健的配置文件進行工作Ubuntu的系統。 (Kickstart configuration files have the extension .cfg.) A kickstart file is created for every Ubuntu system that holds the install responses used for that installation. (突跳起動配置文件的擴展名。 CFG樁。 )在穩健文件被創建為每個Ubuntu的系統,擁有安裝反應用於安裝。 It is located in the root directory at /root/anaconda-ks.cfg.它位於根目錄在/根/安納康達- ks.cfg 。
If you plan to perform the same kind of installation on computers that would be configured in the same way—such as on a local network with hosts that have the same hardware—you could use this kickstart file as a model for performing installations.如果您計劃執行相同類型的計算機上安裝將配置相同的方式,如在本地網絡的主機,有相同的硬件,你可以使用這個穩健的文件作為示範表演設施。 It is a text file that you can edit, with entries for each install response, such as the following for keyboard and time zone:這是一個文本文件,您可以編輯,並為每個條目安裝反應,如以下的鍵盤和時區:
keyboard us我們的鍵盤
timezone America/LosAngeles時美國/洛杉磯
More complex responses may take options such as network, which uses --device for the device interface and bootproto for the boot client:更複雜的反應可能需要選擇,如網絡,它使用-裝置的設備接口和b ootproto的啟動客戶端:
network --device eth0 --bootproto dhcp網絡-e th0這個裝置- bo otproto的D H CP

Many solutions are currently available to work with virtualization, but three of them are particularly important:許多解決方案,目前可與虛擬化,但其中3人是特別重要的:
• VMware • VMware公司
• Xen • Xen的
• KVM (Kernel-based Virtual Machine) •科索沃核查團(內核為基礎的虛擬機)
As for the other solutions, you won’t often find them in a data center because of their considerable limitations, which include a lack of support, a limited selection of operating systems that can be installed as virtual machines, and a severe performance penalty when using them.至於其他的解決辦法,你不會找到他們往往在數據中心,因為他們相當大的限制,其中包括缺乏支持,有限選擇的操作系統,可以安裝虛擬機,並嚴厲處罰時表現使用它們。 For these reasons, I’ll ignore them here, except for one.由於這些原因,我會忽視他們在這裡,除了一個。 If you are interested in running Ubuntu Server in a virtualized environment from a desktop, you should consider installing VirtualBox, which offers an excellent virtualization solution that runs from a graphical desktop.如果您有興趣Ubuntu的服務器運行在虛擬環境中從一個桌面,你應該考慮安裝VirtualBox ,它提供了一個很好的虛擬化解決方案,從圖形桌面。
Of the three important technologies, VMware is the current market leader.這三個重要的技術, VMware是當前市場的領導者。 It offers a commercial solution to virtualize many different operating systems and is a well established virtualization technology that has been available for more than 10 years.它提供了一個商業虛擬化解決許多不同的操作系統,是一個公認的虛擬化技術已經可以超過10年。 The most important VMware version in the data center is VMware ESX.最重要的VMware版本的數據中心是VMware公司的ESX 。 You can use ESX as a virtualization host, on which you will install virtualized machines.您可以使用的ESX作為虛擬主機上,您將安裝虛擬機。 ESX is made of a tuned Linux kernel that integrates the virtual machine manager, which is the process responsible for...的ESX是一個調整的Linux內核,集成了虛擬機的經理,這是該進程負責...
