RedHatEnterpriseLinux5 getting started

I want to learn about Linux, so I don't want to be limited to Windows software development. I also need to be able to adapt to development in the Linux operating system environment. I also found that some enterprise recruitment information mentioned that development experience in Linux is preferred, so I want to write the Linux familiarity into my resume. I am not only interested in Linux. I am very interested in Linux because I will find that Linux is quite different from widows. The essence of Linux lies in the command line. However

I want to learn about Linux, so I don't want to be limited to Windows software development. I also need to be able to adapt to development in the Linux operating system environment. I also found that some enterprise recruitment information mentioned that development experience in Linux is preferred, so I want to write the Linux familiarity into my resume. I am not only interested in Linux. I am very interested in Linux because I will find that Linux is quite different from widows. The essence of Linux lies in the command line. However, different versions of Linux are very different. People who can learn Linux well must be very competent, because there are too many content involved. If they do not have the ability to search materials, they cannot become masters. Of course, I am only a Linux novice, and it takes a long time to get away from the master ....

Linux learning objectives

Master basic command line operations
Modify default system startup Permissions
Configure ftp
Install jdk
Install tomcat
Install mySql

Basic command line operations

I will not talk about it here. Just remember some common commands:

If you want to learn more about these commands, refer to this article: http://www.linuxidc.com/Linux/2013-03/81970.htm

Switch User Permissions

If it is a common user

> The su command can be changed to the system administrator permission.

When you use 'su' you inherit the users pathing, using 'Su-'gives you (root) root's pathing.

When you use su to name the path that inherits the user, use su-to give you the root path

Set vsftpd to automatically load upon startup

[Root @ localhost ~] # Ntsysv

Or

[Root @ localhost ~] # Chkconfig-level 35 vsftpd on

Modify default system startup Permissions

Root permission to enter/etc/inittab

Vi initab modifies the default startup level id: 5: initdefault graphical interface. If you want to change to the default startup command line interface, change 5 to 3.

Enter the reboot command and restart

Startx entry graphical interface
