Nagios installation and configuration (including Nrpe end) All (two)

 Second,      Installation:

1 , MySQL install (if not installed)

# apt-get Install mysql-servermysql-client

2.DBI installation (if not installed)

# cd/usr/local

# wget http://www.cpan.org/modules/by-module/DBI/DBI-1.625.tar.gz
#tar ZXVF dbi-1.625.tar.gz
# CD DBI-1.625
# Perl makefile.pl
#make
# Make Test
# make install

3.DBD installation (if not installed)

# cd/usr/local

# wgethttp://www.cpan.org/modules/by-module/dbd/dbd-mysql-4.023.tar.gz
#tar-ZXVF dbd-mysql-4.023.tar.gz
# CD dbd-mysql-4.023
# perlmakefile.pl

Suppose this is an error. mysql_configis not found , install libmysqlclient-devfirst . Enter the following line command:

# apt-get Installlibmysqlclient-dev

Then

run #perl makefile.pl
# make
# Make install# perl makefile.pl

4 , ndoutils installation

# cd/usr/local

# wgethttp://sourceforge.net/projects/nagios/files/ndoutils-1.x/ndoutils-1.4b7/ndoutils-1.4b7.tar.gz

# TARZXVF ndoutils-1.4b7.tar.gz

# CD Ndoutils -1.4b7

# ./configure--prefix=/usr/local/nagios--enable-mysql--disable-pgsqlldflags=-l/opt/mysql/lib-- With-mysql-inc=/opt/mysql/include/mysql--with-mysql-lib=/opt/mysql/lib/mysql

5 , for ndoutils Create a database

#mysql-U root-p

Enter Password: Enter login password here: root
Mysql>create Database Nagios;
Mysql> Grantselect,insert,update,delete on nagios.* to [email protected] by ' 123456 ';
Mysql> flush Privileges;
Mysql>\q
generate ndoutils required Database
# CD db
#./installdb-u root-p Root-h localhost-d nagios

prompt for done . Log in to MySQL to see a table. :

#mysql-U root-p

enterpassword root

mysql>use Nagios

readingtable information for completion of table and column names

Youcan turn off this feature to get a quicker startup With-a

databasechanged

mysql>show tables;

(

0.00 sec) (correct installation)

6, edit the configuration file

Select, INSERT, update. Delete the number of nagios Database user rights .

# vi/usr/local/nagios/etc/ndo2db.cfg

// the user and user group of the database that was prompted when the installation was complete. # stands for gaze.
Ndo2db_user=nagios

Ndo2db_group=nagios

#socket_type =unix

socket_type=tcp

db_user=root // in front of #./installdb-u root-p root-h localhost-d nagios specified in the

Db_pass=root

# vi/usr/local/nagios/etc/nagios.cfg
# Copy the following paste to #broker_module= ... Following.

# Note that broker_module= and config_file are on one line
broker_module=/usr/local/nagios/bin/ndomod-3x.oconfig_file=/usr/local/nagios/etc/ndomod.cfg

in addition. Make sure that the following lines appear in the /usr/local/nagios/etc/nagios.cfg for example. Otherwise, please join yourself
event_broker_options=-1// open eventbroker for Nagios

# vi/usr/local/nagios/etc/ndomod.cfg

#output_type =file

Output_type=tcpsocket

#output_type =unixsocket

#output =/usr/local/nagios/var/ndo.dat

output=127.0.0.1

#output =/usr/local/nagios/var/ndo.sock

7 . Start ndo2db

Start ndo2db

#/usr/local/nagios/bin/ndo2db-3x-c/usr/local/nagios/etc/ndo2db.cfg

Suppose you are prompted couldnot bind socket:address already in use to delete the ndo.sock :

Rm/usr/local/nagios/var/ndo.sock

set boot up ()

vim/etc/rc.local

Add the following before exit0 :
/usr/local/nagios/bin/ndo2db-3x-c/usr/local/nagios/etc/ndo2db.cfg

To restart the ndo2db method:
Psaux |grep ndo2db Find the process
nagios17539 0.0 0.0 10308 592?

Ss 15:52 0:00/usr/local/nagios/bin/ndo2db-3x-c/usr/local/nagios/etc/ndo2db.cfg
Nagios 17585 0.6 0.2 19528 1560? S 15:52 0:17/usr/local/nagios/bin/ndo2db-3x-c/usr/local/nagios/etc/ndo2db.cfg

Root 18436 0.0 0.1 4588 pts/3s+ 16:39 0:00 grep--color=auto ndo2db

Kill PID numbers such as 17539 and 17585

8.Restart ActionNagios

Check configuration file correctness
#/usr/local/nagios/bin/nagios-v/usr/local/nagios/etc/nagios.cfg

Restart Nagios
#service nagios Restart

Normal situation to this has been completed installation, to go to the database to see if the record has been added

9 , check that the installation is correct
