講解Fedora 10系統(tǒng)下登入GUI
Fedora 10經(jīng)過(guò)長(zhǎng)時(shí)間的發(fā)展，Linux課程實(shí)訓(xùn)，也可作為廣大Linux用戶和Linux系統(tǒng)自學(xué)者的參考很多用戶都很了解Fedora 10了，這里我發(fā)表一下個(gè)人理解，和大家討論討論。
偶然發(fā)現(xiàn)在Fedora 10的GUI登錄窗口，用root登錄的時(shí)候，都會(huì)提示說(shuō)“unable to authenticate user”。切到CLI界面可以正常登錄，Terminal也可以登錄?；蛘哂胮utty也可以登上去。在Fedora的wiki上發(fā)現(xiàn)了這么一段話：
Fedora is a multi-user operating system. Multiple users, each with different access privileges, can be logged into the computer at the same time.
During installation, you provided a password for the system administrator account, sometimes called the superuser. The username for this account is root.
After installation, Fedora asked you to set up a normal user account. Use that account, or another normal account, for daily use of the system. and the root account for administrative and maintenance tasks.
This design has many benefits:
Limited privileges reduce the possibility of doing significant damage to the entire system.
Each user account has individual settings.
Each user account maintains its data separate and private from others.
A problem in one user account does not put the entire system at risk.
Do not login as root
Do not use the root account for routine purposes. A normal user account can run all desktop applications, and greatly increases your security and safety. Applications that require root privileges prompt you for the root password when they start, so you need not login as root to use them.
翻譯過(guò)來(lái)就是：
Fedora 10是一個(gè)多用戶的操作系統(tǒng)。不同的用戶，各自擁有不同的權(quán)限，可以在同一時(shí)間登錄計(jì)算機(jī)。在安裝過(guò)程中，你為系統(tǒng)管理員賬戶，有時(shí)也叫做超級(jí)用戶，提供了一個(gè)密碼。這個(gè)帳戶的用戶名是root。 安裝完成后，F(xiàn)edora 10會(huì)要求你設(shè)置一個(gè)普通用戶賬戶。這個(gè)賬戶或者其他普通賬戶，用于計(jì)算機(jī)的日常使用，root賬戶用于管理和維護(hù)工作。
這樣的設(shè)計(jì)有很多好處：被限制的權(quán)限減少了對(duì)整個(gè)系統(tǒng)大規(guī)模破壞的可能性每個(gè)用戶賬戶擁有個(gè)人的設(shè)置每個(gè)用戶賬戶各自維護(hù)自己的數(shù)據(jù)并不對(duì)其他賬戶公開(kāi)一個(gè)用戶帳戶的問(wèn)題不會(huì)使整個(gè)系統(tǒng)處于危險(xiǎn)之中.
不要用root登錄
在Fedora 10系統(tǒng)下不要拿root賬戶用于一般的目的。普通賬戶可以運(yùn)行所有的桌面程序，并且可以大幅提升你的保密性和安全性。需要root權(quán)限的程序在啟動(dòng)會(huì)提示你輸入root密碼，所以你不需要用root身份登錄來(lái)使用他們。似乎是因?yàn)閞oot的權(quán)限太大了，才故意把root的GUI登錄禁用的吧。網(wǎng)上也可以找到能夠讓root登錄GUI的方法，為了安全考慮，還是沒(méi)有去試了。
