linux 架设nagios+cacti+nconf完整配置，生产环境中的配置

admin · 发表于 2016-11-12 12:11:01

下面是配置全过程

1.先安装各个nagios+cacti的依赖包

更新源rpm -ivh http://download.fedora.redhat.co ... ease-6-5.noarch.rpm
yum update

yum -y install httpd php php-gd freetype php-mysql php-snmp php-devel mysql mysql-server perl-DBD-MySQL php-pdo net-snmp net-snmp-libs net-snmp-utils net-snmp-devel ruby ruby-devel gcc glibc glibc-common gd gd-devel ntp

yum -y install httpd gcc gcc-c++ glibc glibc-common gd* gd-devel php php-mysql mysql mysql-server mysql-devel openssl-devel (nagios安装需要的依赖包)

yum install httpd php php-mysql php-snmp mysql perl-dbd-mysql php-pdo net-snmp-libs net-snmp-utils perl-rrdtool rrdtool-devel rrdtool    *       (cacti需要)

再安装其他必要包
yum -y install php-pdo lm_sensors php-snmp net-snmp-utils net-snmp-libs perl-net-naemon perl-pirpc perl-dbi perl-dbd-mysql libcgi glib

yum install php-mcrypt libmcrypt mhash (phpmyadmin需要)

安装webmin
wget http://prdownloads.sourceforge.n ... -1.580-1.noarch.rpm
rpm -ivh  /home/sotf/webmin/webmin-1.580-1.noarch.rpm
iptables -I INPUT -p tcp --dport 10000 -j ACCEPT

安装nagios
useradd nagios
usermod -a –G nagios apache
wget http://prdownloads.sourceforge.n ... nagios-3.3.1.tar.gz
cd nagios
tar zxvf nagios
./configure --with-nagios-user=nagios --with-nagios-group=nagios --with-command-group=nagios --with-gd-lib=/usr/lib --with-gd-inc=/usr/include --enable-event-broker --enable-embedded-perl
make all
make install
make install-init
make install-commandmode
make install-config
make install-webconf
make install-exfoliation
make install-classicui
service httpd restart
htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
安装nagios-plugin
wget http://prdownloads.sourceforge.n ... ugins-1.4.15.tar.gz
tar zxvf nagios-plugins
./configure --with-nagios-user=nagios --with-nagios-group=nagios --with-mysql --with-gnutls --enable-extra-opts --enable-perl-modules --enable-libtap --with-openssl

make
make install
chkconfig –add nagios
chkconfig nagios on
vim /etc/profile
export PATH=$PATH:/usr/local/nagios/bin
service nagios start

setenforce 0

安装addon
http://prdownloads.sourceforge.net/sourceforge/nagios/nrpe-2.13.tar.gz

tar zxvf nrpe
./configure --enable-ssl --with-ssl-lib=/lib/
make
make install

chown -R nagios.nagios /usr/local/nagios/libexec/

检查配置文件是否正确 :/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg service nagios start
注意:如果你开启了 selinux 需要配置如下二步:
chcon -R -t httpd_sys_content_t /usr/local/nagios/sbin/
chcon -R -t httpd_sys_content_t /usr/local/nagios/share/

安装CACTI
rrdtool

wget http://packages.express.org/rrdt ... -1.el5.wrl.i386.rpm
wget http://packages.express.org/rrdt ... -1.el5.wrl.i386.rpm
wget http://flexbox.sourceforge.net/c ... .4.4-1.el5.i386.rpm

yum localinstall -y --nogpgcheck rrdtool-*

配置snmp

create database cacti;
grant all on cacti.* to 'cacti'@'localhost' identified by 'cacti';
flush privileges;
quit

cd /var/www/html/cacti/
mysql -ucacti -pcacti cacti < /var/www/html/cacti/cacti.sql
vim /var/www/html/cacti/include/config.php
spacer.gif
vim /var/www/html/cacti/include/global.php
spacer.gif

useradd -r -M cacti
chown -R cacti /var/www/html/cacti/rra/
chown -R cacti /var/www/html/cacti/log/

su cacti
crontab –e
*/5 * * * * php /var/www/html/cacti/poller.php > /dev/null 2>&1
php /var/www/html/cacti/poller.php
exit

进入网页配置

整合nagios与cacti
安装ndoutils
下载ndoutils
tar xvf ndoutils-1-5.tar
cd ndoutils-1-5
./configure --enable-mysql --disable-pgsql --with-mysql-inc=/usr/include/mysql --with-mysql-lib=/usr/lib/mysql
make
cd src
cp ndomod-3x.o ndo2db-3x file2sock log2ndo /usr/local/nagios/bin/
cd ../db
./installdb -u cacti -p cacti -h localhost -d cacti
cd ../config
cp ndo2db.cfg-sample ndo2db.cfg
cp ndomod.cfg-sample ndomod.cfg
cp ndo2db.cfg ndomod.cfg /usr/local/nagios/etc/
chmod 644 /usr/local/nagios/etc/ndo*
chown nagios.nagios /usr/local/nagios/etc/*
chown nagios.nagios /usr/local/nagios/bin/*

修改nagios.cfg配置
spacer.gif
broker_module=/usr/local/nagios/bin/ndomod-3x.o config_file=/usr/local/nagios/etc/ndomod.cfg

修改ndo2db.cfg
spacer.gif

修改ndomod.cfg
25 output_type=tcpsocket
39 output=127.0.0.1
添加ndo2db服务启动
cd /home/soft/nagios/addon/ndoutils-1-5
cp daemon-init /etc/init.d/ndo2db
vim /etc/init.d/ndo2db
spacer.gif
chmod +x /etc/init.d/ndo2db
service ndo2db start
chkconfig ndo2db on
service nagios restart

安装ncp
安装cacti-plugin
tar zxvf cacti-plugin-0.8.7h-PA-v3.0.tar.gz
cp -R cacti-plugin-arch/* /var/www/html/cacti/
mysql -ucacti -pcacti cacti<pa.sqlpatch -p1 -N < cacti-plugin-0.8.7h-PA-v3.0.diff
vim include/config.php
$url_path = "/cacti/";

下载npc
tar xvf npc
mv npc /var/www/html/cacti/plugins/
vim /var/www/html/cacti/include/config.php
$plugins[] = 'npc';

npc需要安装json
tar xzvf json-1.2.1.tgz
cd json-1.2.1
phpize
./configure
make
make install
php -i | grep php.ini
vim /etc/php.ini
spacer.gif

vim /etc/httpd/conf/httpd.conf
spacer.gif

usermod -G cacti apache
service httpd restart
php -m

vim /var/www/html/nagios/etc/ndo2db.cfg
111 db_prefix=npc_

mysql -u cacti -p cacti
use cacti;
alter table npc_eventhandlers add long_output TEXT NOT NULL default '' after output;
alter table npc_hostchecks add long_output TEXT NOT NULL default '' after output;
alter table npc_hoststatus add long_output TEXT NOT NULL default '' after output;
alter table npc_notifications add long_output TEXT NOT NULL default '' after output;
alter table npc_servicechecks add long_output TEXT NOT NULL default '' after output;
alter table npc_servicestatus add long_output TEXT NOT NULL default '' after output;
alter table npc_statehistory add long_output TEXT NOT NULL default '' after output;
alter table npc_systemcommands add long_output TEXT NOT NULL default '' after output;
quit

安装nconf
mysql
create database nconf;
grant all privileges on nconf.* to nconf@localhost identified by 'nconf';
flush privileges;
quit

tar xvf nconf-1.2.6-0.tgz -C /var/www/html/
cd /var/www/html/nconf/
chown -R apache.apache config/ temp/ static_cfg/ output/

进入web页面配置好
rm -rf INSTALL INSTALL.php UPDATE UPDATE.php
ln -s /usr/local/nagios/bin/nagios bin/nagios
chown -R apache.apache bin
chmod +x /usr/local/nagios/bin/nagios
chmod +x /var/www/html/nconf/ADD-ONS/deploy_local.sh
vim /var/www/html/nconf/ADD-ONE/deploy_local.sh

spacer.gif

打开selinux需要添加如下
chcon -t httpd_sys_script_exec_t /var/www/html/nconf/bin/nagios

vim /usr/local/nagios/etc/nagios.cfg
spacer.gif

安装cacti-spin
tar xvf cacti-spine
./configure
make
make install
到页面设置路径

加入运行sh
*/1 * * * *  /var/www/html/nconf/ADD-ONS/deploy_local.sh

必定要看/usr/local/nagios/etc下的文件权限问题
最后要chown –R nagios.nagios etc

最后将crontab全部改为1分钟

上面是安装server端已经完成，下面配置client
请search:"添加被监控server的详细配置"
添加完后某些服务需要监控才能够修改。look it this notes
nagios 修改用户密码验证配置开启
#验证naigios配置的正确性
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
#验证通过以后可以执行下面命令作为守护进程
/usr/local/nagios -d /usr/local/nagios/etc/nagios.cfg
#更改web用户名和密码
1.ee /usr/local/nagios/etc/htpasswd.users
2.编辑/usr/local/nagios/etc/cig.cfg |grep 'authorized'
文件，将开始建立的用户名test添加到里面，允许该账户通过web登陆（如果有多个登陆账号，在后面用,号隔开）。
