Redhat Enterprise Linux - Start service on boot




Redhat enterprise Linux comes with two nice commands
ntsysv - simple TUI (text based interface) interface for configuring runlevels. 

chkconfig - chkconfig provides a simple command-line tool for maintaining the /etc/rc[0-6].d directory hierarchy by relieving system administrators of the task of directly manipulating the numerous symbolic links in those directories.

Turn on sshd service on boot
Code:
chkconfig sshd on
Turn on MySQL service on boot
Code:
chkconfig mysqld on
Turn on Apache / httpd service on boot
Code:
chkconfig httpd on
Turn OFF Apache / httpd service on boot
Code:
chkconfig httpd off
List if service is on of off on boot
Use --list option which lists all of the services which chkconfig knows about, and whether they are stopped or started in each runlevel:
Code:
/sbin/chkconfig --list
Sample O/p of above command

Machine Learning

                                                    Machine Learning Machine Learning, a subset of AI, uses computer algorithms to analyze data and make intelligent decisions based on what it has learned. Instead of following rules-based algorithms, machine learning builds models to classify and make predictions from data. Let's understand this by exploring a problem we may be able to tackle with Machine Learning.  What if we want to determine whether a heart can fail, is this something we can solve with Machine Learning? The answer is, Yes. Let's say we are given data such as beats per minute, body mass index, age, sex, and the result whether the heart has failed or not. With Machine Learning given this dataset, we are able to learn and create a mode...
