The difference between "Xiao-CentOS" and "Ubuntu"

CentOS (Community ENTerprise operating System) is one of the Linux distributions that is compiled from the source code released by Red Hat ENTerprise Linux in accordance with open source rules. Because of the same source code, some servers that require a high degree of stability are used by CentOS instead of the commercial version of Red Hat Enterprise Linux.

Ubuntu is a desktop application based Linux operating system, the name "Ubuntu" from the southern African Zulu or Hausa language (translated into my Help or the Bantu), meaning "human nature", "I exist because everyone exists", is a traditional African values, similar to the Chinese society " Benevolence "thought. Based on the Debian distribution and GNOME desktop environment, Ubuntu differs from Debian in that it publishes a new version every 6 months. The goal of Ubuntu is to provide an up-to-date and fairly stable operating system built primarily of free software for the average user. Ubuntu has a huge community strength, and users can easily get help from the community.

Both of the current version of the individual and small teams commonly used service-level operating systems, online provided by the software library can be easily installed in many open source software and libraries. Both use bash as the base shell, so the difference between Ubuntu and CentOS is not obvious on many basic commands, and Ubuntu is doing better on the desktop interface, and many people who are interested in learning Linux are usually the first choice for Ubuntu, After all, many people are still very accustomed to working under the desktop graphics. There are still a lot of differences between CentOS and Ubuntu's usage and commands, and here's a quick list:

1.centos new non-root users do not have sudo permissions, if you need to use sudo permissions must be in the/etc/sudoers to add accounts and permissions, so switch to the root account only need to input: Su, add the root account password.

In Ubuntu, the sudo+ command is generally used, which prompts for the current user's password (instead of the root password) if it is used for the first time.

2. In the online installation software, CentOS is using the Yum command, while Ubuntu uses the Apt-get command. In addition, there is a yum from the software source to search for a software method: Yum search + software name

3.centos is from Redhat, so CentOS supports the RPM format installation, and Ubuntu is clearly not supported.

4. After all, different companies do different distributions, a lot of configuration file location and the default file path are very different, this need to use the process slowly realized.
