How to Install & Setup Monit on Ubuntu

Installing monit on Ubuntu 

Installing a package from the distribution repository

$ sudo apt-get install monit

Download the latest version from here http://mmonit.com/monit/

$ cd /usr/src/


Extract tar file

$ tar zxvf monit-5.5.tar.gz

$ mv monit-5.5/ monit/

Compiling from source

$ cd monit/

$ ./configure

$ sudo make && make install

Monit control file:

$ cp /usr/src/monit/monitrc ~/.monitrc

$ sudo chmod 0700 .monitrc

Configure Monit :

$ sudo vi /etc/monit/monitrc

Monit comes with its own web server running on port 2812. To configure the web interface, find and uncomment the section that begins with.set httpd port 2812 Once the section is uncommented, write in your server’s IP or domain name as the address, allow anyone to connect, and then create a monit user and password
set httpd port 2812
    use address 12.34.56.789  # only accept connection from localhost
    allow 0.0.0.0/0.0.0.0        # allow localhost to connect to the server and
    allow admin:monit      # require user 'admin' with password 'monit'

$ sudo service monit restart

Configuring Programs Self-Monitoring :

To simply ensure that programs stay online, you can use the /etc/init.d commands to stop or start a program.

$ sudo vi /etc/monit/monitrc

Here are some example configurations:
Apache:
check process apache with pidfile /run/apache2.pid
    start program = "/etc/init.d/apache2 start" with timeout 60 seconds
    stop program  = "/etc/init.d/apache2 stop"
MySQL
check process mysqld with pidfile /var/run/mysqld/mysqld.pid
    start program = "/etc/init.d/mysql start"
    stop program = "/etc/init.d/mysql stop"
Nginx
check process nginx with pidfile /var/run/nginx.pid
    start program = "/etc/init.d/nginx start"
    stop program = "/etc/init.d/nginx stop"

Java Loops II print each element of our series as a single line of space-separated values.

We use the integers  ,  , and   to create the following series: You are given   queries in the form of  ,  , and  . For each query, print the series corresponding to the given  ,  , and   values as a single line of   space-separated integers. Input Format The first line contains an integer,  , denoting the number of queries.  Each line   of the   subsequent lines contains three space-separated integers describing the respective  ,  , and   values for that query. Constraints Output Format For each query, print the corresponding series on a new line. Each series must be printed in order as a single line of   space-separated integers. Sample Input 2 0 2 10 5 3 5 Sample Output 2 6 14 30 62 126 254 510 1022 2046 8 14 26 50 98 Explanation We have two queries: We use  ...
