Otro apunte, para instalar nagios3 en una Debian.
\nPrimero, instalamos unas dependencias b\u00e1sicas:
\n
\n#aptitude install build-essential gcc libgd2-xpm-dev libglib2.0-dev apache2
\n<\/code>
\nCreeamos usuario y grupo:
\n
\n# \/usr\/sbin\/useradd nagios
\n# passwd nagios
\n# \/usr\/sbin\/groupadd nagcmd
\n#\/usr\/sbin\/usermod -G nagcmd nagios
\n# \/usr\/sbin\/usermod -G nagcmd www-data
\n<\/code>
\nAhora instalamos unas dependencias b\u00e1sicas:
\n
\nroot@nagios:~# apt-get install apache2 mc libapache2-mod-php5 php5-cli php5-common php5-cgi php5-gd
\nroot@nagios:~# aptitude install build-essential gcc libgd2-xpm-dev libglib2.0-dev apache2
\nroot@nagios:~# apt-get install php5-cli php5-common php5-gd
\nroot@nagios:~# apt-get install libjpeg62 libjpeg62-dev libpng12-0 libpng12-dev
\nroot@nagios:~# apt-get install php5-cli php5-common php5-gd php-pear
\nroot@nagios:~# apt-get install ssh apache2 libapache2-mod-php5 php5-cli php5-common php5-cgi php5-gd -qy bison flex libncurses5-dev zlib1g-dev libssl-dev libnewt-dev libiksemel-dev -qy make linux-headers-`uname -r` gcc g++ libstdc++6 mysql-client mysql-server phpmyadmin linux-headers-`uname -r` bison openssl libssl-dev libeditline0 libeditline-dev libedit-dev gcc make g++ php5-cli mysql-common libmysqlclient15-dev libnewt-dev libmysqlclient15-dev libnewt-dev
\n<\/code>
\nY reiniciamos apache2:
\n
\nroot@nagios:~# \/etc\/init.d\/apache2 restart
\n<\/code>
\nY seguimos a\u00f1adiendo usuarios y grupos :
\n
\nroot@nagios:~# \/usr\/sbin\/useradd nagios
\nroot@nagios:~# passwd nagios
\nroot@nagios:~# \/usr\/sbin\/groupadd nagcmd
\nroot@nagios:~# \/usr\/sbin\/usermod -G nagcmd nagios
\nroot@nagios:~# \/usr\/sbin\/usermod -G nagcmd www-data
\n<\/code>
\nAhora descargamos el nagios en \/usr\/src y creamos un directorio para ello y lo descomprimimos:
\n
\nroot@nagios:~# cd \/usr\/src\/
\nroot@nagios:~# mkdir nagios
\nroot@nagios:~# cd nagios\/
\nroot@nagios:~# wget -c https:\/\/sourceforge.net\/projects\/nagios\/files\/nagios-3.x\/nagios-3.4.1\/nagios-3.4.1.tar.gz\/download
\nroot@nagios:~# tar -zxvf nagios-3.4.1.tar.gz
\nroot@nagios:~# wget -c https:\/\/sourceforge.net\/projects\/nagiosplug\/files\/nagiosplug\/1.4.15\/nagios-plugins-1.4.15.tar.gz\/download
\nroot@nagios:~# tar -zxvf nagios-plugins-1.4.15.tar.gz
\n<\/code>
\nY ahora a compilar:
\n
\nroot@nagios:\/usr\/src\/nagios# .\/configure --with-command-group=nagcmd
\nroot@nagios:\/usr\/src\/nagios# make all
\nroot@nagios:\/usr\/src\/nagios# make install
\nroot@nagios:\/usr\/src\/nagios# make install-init
\nroot@nagios:\/usr\/src\/nagios# make install-config
\nroot@nagios:\/usr\/src\/nagios# make install-commandmode
\nroot@nagios:\/usr\/src\/nagios# make install-webconf
\n<\/code>
\nCreamos el usuario para el acceso web:
\n
\nroot@nagios:\/usr\/src\/nagios# htpasswd -c \/usr\/local\/nagios\/etc\/htpasswd.users nagiosadmin
\n<\/code>
\nY ahora toca el nagios-plugins
\n
\nroot@nagios:\/usr\/src\/nagios# cd nagios-plugins-1.4.15\/
\nroot@nagios:\/usr\/src\/nagios\/nagios-plugins-1.4.15# .\/configure --with-nagios-user=nagios --with-nagios-group=nagcmd
\nroot@nagios:\/usr\/src\/nagios# make
\nroot@nagios:\/usr\/src\/nagios# make install
\n<\/code>
\nAhora instalamos la parte para que env\u00ed\u00ade las notificaciones:
\n
\nroot@nagios:\/usr\/local\/nagios\/share# apt-get remove exim4 exim4-config
\nroot@nagios:\/usr\/local\/nagios\/share# apt-get install postfix postfix-doc
\n<\/code>
\nY configuramos el main.cf de postfix, tal que:
\n
\nmyhostname = nagios.dominio.local
\nmydomain = dominio.local
\nmyorgin = $mydomain
\nmasquerade_domain = $mydomain
\nmydestination = $myhostname, localhost.$mydomain, $mydomain
\nmynetwork_style = host
\n##########################################################
\nmynetworks = 192.168.0.0\/16
\nrelay_domains = dominio.local
\ntransport_maps = hash:\/etc\/postfix\/transport
\nbounce_notice_recipient = email@dominio.com
\ndelay_notice_recipient = email@dominio.com
\n2bounce_notice_recipient = email@dominio.com
\nerror_notice_recipient = email@dominio.com
\ndefault_destination_concurrency_limit = 10
\nsmtpd_recipient_limit = 100
\nmaximal_queue_lifetime = 1d
\nfallback_relay =
\nsmtp_destination_recipient_limit = 200
\nsmtp_destination_concurrency_limit = 10
\nmessage_size_limit = 5240000
\nappend_at_myorigin = yes
\nappend_dot_mydomain = no
\nswap_bangpath = no
\n<\/code>
\nY reiniciamos postfix:
\n
\nroot@nagios:\/etc\/postfix# \/etc\/init.d\/postfix restart
\nStopping Postfix Mail Transport Agent: postfix.
\nStarting Postfix Mail Transport Agent: postfix.
\nroot@nagios:\/etc\/postfix#
\n<\/code>
\nY ahora toca configurar plugins y resto de cosillas.
\nEnjoy your nagios \ud83d\ude42<\/p>\n","protected":false},"excerpt":{"rendered":"
