Linux Books

Of course the Internet along with the help of Google is a great source of information. You can answer almost any question you have about Linux and find many tutorials, guides and help. However many people prefer reading this information on a printed book accesssible even when they are not online or don't have a computer in front of them. I've received many e-mails asking me to propose them a few good books regarding Linux commands, administration and for specific distributions such as Ubuntu, Fedora etc. So, I've search for a few good books. Here they are. Happy reading!

1. 从 Fedora 7/8/9 升级

**注意: 在升级之前备份所有重要数据总是必要的。

Fedora 使用预升级(Preupgrade)技术可以非常容易的升级到最新的发行版,它通过网上下载最新的安装包而无需下载(光盘镜像文件)并刻录成 CD 或者 DVD 。预升级技术解决了所有依赖,下载所需升级包,配置 grub ,最后询问用户重启就完成了升级过程。请确保你当前的系统已经更新到最新,然后输入下面的命令安装并运行预升级:

su -c 'yum update'
yum install preupgrade
preupgrade

选择 Fedora 10 ,稍加等待之后系统提示你重启,你的系统已经升级到 Fedora 10 了!

如果你一直在使用 RPM Fusion ,你的系统现在应该已经升级到 RPM Fusion 软件仓库了。但即使你没有升级到 RPM Fusion 软件仓库,整个系统升级之后它也会随之升级的。

2. 配置sudo

**注意: 在我之前的 Fedora 6、7指南中,在需要根权限执行命令的时候我一直使用 sudo 。因为很多用户不愿意添加自己的系统帐号到 sudoer (可以使用sudo的用户)组,因此我决定改变命令为 su -c 'command' 。如果你想以根用户输入大量的命令,你第一次输入命令的时候输入 su - 并且输入你的根密码。之后,在你输入 exit 之前,你一直都是根用户权限。当然,你还是自己决定是否配置 sudo 吧。

* 编辑 sudoer 文件

正常情况下,如果你想输入需要根用户权限的命令,你首先必须输入“su -”,然后输入你的根密码,然后再输入命令。当然你可以使用 sudo 命令掠过这一步,但首先你必须如下配置:

su --login -c 'visudo'
移到这一行下面:

root    ALL=(ALL)       ALL
按 A 键,输入下面一行

username ALL=(ALL)      ALL
需要用户名的地方输入你登录时使用的用户名,然后按 ESC 键。

如果你想每次使用 sudo 命令的时候都提示你输入根密码,将光标移动到这一行的下面:

# %wheel        ALL=(ALL)       ALL
将光标指向 # 并按 x 键

如果你不想每次使用 sudo 命令的时候都提示你输入跟密码,移动到下面这一行:

# %wheel        ALL=(ALL)       NOPASSWD: ALL
将你的光标指向 # 并按 x 键

接着按 :wq 键保存退出(:也需要按一下)

*添加你的用户到 wheel 组

只需要输入:

su -c 'gpasswd -a username wheel'

* 测试 sudo

测试你自己是否正确配置了 sudo ,只需要在普通用户权限下输入:

$ sudo whoami
如果一切正常,命令会返回 “root” 这个字。
