cacti + nagios + npc 整合部署
centos5.5 + cacti + nagios + ?npc
都是用的yum做的，軟件版本如下：
cacti-0.8.7e.tar.gz
cacti-plugin-0.8.7e-PA-v2.6.zip
nagios-3.4.1.tar.gz
nagios-plugins-1.4.16.tar.gz
ndoutils-1.4b9.tar.gz
npc-2.0.4.tar.gz
PDO_MYSQL-1.0.2.tgz
php-json-ext-1.2.1.tar.gz
rrdtool-1.4.4.tar.gz
一、安裝環(huán)境LAMP
#yum -y install *gcc*
#yum -y install httpd httpd-manual mysql mysql-devel mysql-server php php-devel php-mysql php-common php-pdo php-gd lm_sensors net-snmp php-snmp net-snmp-utils
# chkconfig mysqld on
# chkconfig httpd on
# chkconfig snmpd on
# service mysqld start
# service httpd start
# service snmpd start
# mysqladmin -u root password 'redhat321'
# mysql -u root -p
:輸入密碼
mysql>create database cacti;
Query OK, 1 row affected (0.00 sec)
mysql>grant all on cacti.* to cactiadmin@localhost identified by 'cacti321';
Query OK, 0 rows affected (0.01 sec)
mysql>flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> \q
二、安裝cacti
1、安裝rrdtool需要的軟件包
# yum -y install ?cairo-devel libxml2-devel pango pango-devel
2、安裝rrdtool
# tar xf rrdtool-1.4.4.tar.gz
# cd rrdtool-1.4.4
# ./configure --prefix=/usr/local/rrdtool && make && make install
# ln -s /usr/local/rrdtool/bin/* /usr/local/bin/
3、安裝cacti-0.8.7.e
# tar xf cacti-0.8.7e.tar.gz -C /var/www/html/
# cd /var/www/html/
# mv cacti-0.8.7e/ cacti
# chown -R root.root /var/www/html/cacti/
4、導(dǎo)入數(shù)據(jù)庫
# mysql -u root -p cacti <cacti/cacti.sql
Enter password:
5、修改cacti配置文件，連接數(shù)據(jù)庫
# vim /var/www/html/cacti/include/config.php
$database_username = "cactiadmin";
$database_password = "cacti321";
# vim /var/www/html/cacti/include/global.php
$database_username = "cactiadmin";
$database_password = "cacti321";
6、安裝插件cacti-plugin
# wget http://mirror.cactiusers.org/downloads/plugins/cacti-plugin-0.8.7e-PA-v2.6.zip
# unzip cacti-plugin-0.8.7e-PA-v2.6.zip
# cd cacti-plugin-arch/
# cp cacti-plugin-arch/{cacti-plugin-0.8.7e-PA-v2.6.diff,pa.sql} /var/www/html/cacti/
# cd /var/www/html/cacti/
7、打補丁導(dǎo)入數(shù)據(jù)庫
# patch -p1 -N <cacti-plugin-0.8.7e-PA-v2.6.diff
# mysql -uroot -p cacti<pa.sql
8、修改配置文件，如下：
# vim include/global.php
$config['url_path'] = '/cacti/';
9、添加計劃任務(wù)
# crontab -e
*/5 * * * * /usr/bin/php /var/www/html/cacti/poller.php
# service crond restart
10、瀏覽器輸入http://192.168.163.143/cacti/install初始化cacti，最后如下：
另外cacti無法顯示圖片，圖片顯紅叉，但是點進(jìn)去有圖：
解決方法：
settings里面的RRDTOOLS版本設(shè)置不對，默認(rèn)為1.0.x，改為1.2.x就行了。
三、被監(jiān)控端配置
1、安裝snmp服務(wù)
# rpm -ivh ?lm_sensors-2.10.7-4.el5.i386.rpm ?net-snmp-5.3.2.2-7.el5.i386.rpm
2、修改配置文件如下：（這里我省略掉了#行和空行）
# vim /etc/snmp/snmpd.conf
com2sec notConfigUser default public
group notConfigGroup v1 notConfigUser
group notConfigGroup v2c notConfigUser
view systemview included .1.3.6.1.2.1.1
view systemview included .1.3.6.1.2.1.25.1.1
access notConfigGroup "" any noauth exact mib2 none none
view mib2 included .iso.org.dod.internet.mgmt.mib-2 fc
syslocation Unknown (edit /etc/snmp/snmpd.conf)
syscontact Root <root@localhost> (configure /etc/snmp/snmp.local.conf)
pass .1.3.6.1.4.1.4413.4.1 /usr/bin/ucd5820stat
3、重啟服務(wù)
# service snmpd ?restart
到此就差不多了，我們可以做些檢測在服務(wù)器上，有信息返回說名正常：
# snmpwalk -v 2c -c public ServerIP if
四、安裝nagios
1、建立用戶
# useradd -s /sbin/nologins nagios
# mkdir -p /usr/local/nagios
# chown -R ?nagios.nagios /usr/local/nagios/
2、編譯安裝nagios
# tar xf nagios-3.4.1.tar.gz
# cd nagios
# ./configure --prefix=/usr/local/nagios/
# make all
# make install
# make install-init
# make install-commandmode
# make install-config
# make install-webconf
# chkconfig --add nagios
# chkconfig nagios on
# service nagios start
3、安裝插件
# tar xf nagios-plugins-1.4.16.tar.gz
# cd nagios-plugins-1.4.16
# ./configure --prefix=/usr/local/nagios/ && make && make install
4、修改apache的配置文件
# vim /etc/httpd/conf/httpd.conf
最后添加如下內(nèi)容，設(shè)置成需要輸入密碼才能登陸
ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"
<Directory "/usr/local/nagios/sbin">
AuthType Basic
Options ExecCGI
AllowOverride ? None
Order allow,deny
Allow from all
AuthName "Nagions Access"
AuthUserFile /usr/local/nagios/etc/htpasswd
Require valid-user
</Directory>
Alias /nagios ? "/usr/local/nagios/share"
<Directory "/usr/local/nagios/share">
AuthType Basic
Options None
AllowOverride None
Order allow,deny
Allow from all
AuthName "Nagios Access"
AuthUserFile /usr/local/nagios/etc/htpasswd
Require valid-user
</Directory>
5、配置nagios添加主機，服務(wù)信息
在/usr/local/nagios/etc/objects/下建立2個文件：
（1）hosts.cfg定義主機的文件
define host{
use linux-server
host_name 192.168.163.143
alias 192.168.163.143
address 192.168.163.143
}
（2）services.cfg 定義主機服務(wù)的文件
define service{
use local-service ?//引用local-service的屬性信息，在template.cfg中定義
host_name 192.168.163.143 //監(jiān)控那個主機，host-142在hosts.cfg中定義
service_description ssh //對監(jiān)控內(nèi)容的描述
check_command check_ssh //指定監(jiān)控的命令，check_ping在commands.cfg中定義
}
define service{
use local-service
host_name 192.168.163.143
service_description Ping
check_command check_ping
}
# chown nagios.nagios /usr/local/nagios/etc/objects/{hosts.cfg,services.cfg}
6、建立登陸的用戶名密碼
# htpasswd -c ?/usr/local/nagios/etc/htpasswd nagiosadmin
7、修改nagios.cfg文件，添加文件路徑信息：
cfg_file=/usr/local/nagios/etc/objects/hosts.cfg
cfg_file=/usr/local/nagios/etc/objects/services.cfg
cfg_file=/usr/local/nagios/etc/objects/commands.cfg
cfg_file=/usr/local/nagios/etc/objects/contacts.cfg
cfg_file=/usr/local/nagios/etc/objects/timeperiods.cfg
cfg_file=/usr/local/nagios/etc/objects/templates.cfg
8、啟動nagios以后訪問輸入用戶名密碼就可以看到Nagios了
如果啟動有問題，可以使用下面的命令檢查：
# ?/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
四、整合cacti+nagios
整合cacti和nagios是利用了cacti的一個插件nagios for ?cacti，它的原理是將nagios的數(shù)據(jù)通過ndo2db導(dǎo)入到mysql數(shù)據(jù)庫（cacti的庫中），然后cacti讀取數(shù)據(jù)庫信息將nagios
的結(jié)果展示出來。
1、安裝php-json擴展，因為NPC使用了ExtJS，如過沒有json的擴展NPC界面無法出來。
# tar xf php-json-ext-1.2.1.tar.gz
# cd php-json-ext-1.2.1
# phpize
如果沒有命令的話安裝下面的軟件包
# rpm -ihv /media/CentOS/php-devel-5.1.6-27.el5.i386.rpm
# sh configure && make && make install
2、新建文件，添加信息如下：
# vim /etc/php.d/json.ini
extension=json.so
安裝完成后如果先驗證的話，可以寫個index.php的頁面看下，有json信息即可，如下：
3、安裝ndoutils，需要安裝mysql-devel前面已經(jīng)裝過這里就不用再裝了
# tar xf ndoutils-1.4b9.tar.gz
# cd ndoutils-1.4b9
# ./configure --with-mysql-inc=/usr/include/mysql --with-mysql-lib=/usr/lib/mysql --enable-mysql --with-ndo2db-user=nagios--with-ndo2db-group=nagios
# make（不用make install）
4、復(fù)制文件
# cp src/{ndomod-3x.o,ndo2db-3x,log2ndo,file2sock} /usr/bin/
# cp config/ndo2db.cfg-sample /usr/local/nagios/etc/ndo2db.cfg
# cp config/ndomod.cfg-sample /usr/local/nagios/etc/ndomod.cfg
# chmod 644 /var/www/html/nagios/etc/ndo*
5、修復(fù)配置文件信息，連接數(shù)據(jù)庫
# vim /usr/local/nagios/etc/ndo2db.cfg
socket_type=tcp
db_host=127.0.0.1
db_port=3306
db_name=cacti
db_prefix=npc_
db_user=cactiadmin
db_pass=cacti321
debug_level=1
# vim /usr/local/nagios/etc/ndomod.cfg
output_type=tcpsocket
output=127.0.0.1
6、添加啟動腳本，并修改Ndo2dbBin
# cp /download/ndoutils-1.4b9/daemon-init /etc/init.d/ndo2db
# vim /etc/init.d/ndo2db
Ndo2dbBin=/usr/bin/ndo2db-3x
# chmod +x /etc/init.d/ndo2db
# service ndo2db start
7、安裝npc
# tar xf npc-2.0.4.tar.gz
# mv npc /var/www/html/cacti/plugins/
修改配置文件，添加如下信息
# vim /var/www/html/cacti/include/global.php
$plugins = array();
$plugins[]='npc';
8、修改nagios添加信息：
# vim /usr/local/nagios/etc/nagios.cfg
broker_module=/usr/bin/ndomod-3x.o config_file=/usr/local/nagios/etc/ndomod.cfg
event_broker_options=-1
# service nagios restar
啟動之后在cacti中添加npc，如下：
當(dāng)訪問到npc這個頁面的時候已經(jīng)擦不多了
9、但是看npc里發(fā)現(xiàn)空白的，沒有數(shù)據(jù)，是因為php沒有PDO_MYSQL支持，所以安裝PDO_MYSQL
# wget http://pecl.php.net/get/PDO_MYSQL-1.0.2.tgz
# tar zxvf PDO_MYSQL-1.0.2.tgz
# cd PDO_MYSQL-1.0.2
# /usr/local/php/bin/phpize
#./configure --with-php-config=/usr/bin/php-config
#make
#make install
修改php.ini，添加如下信息，之后重啟httpd即可
extension = "pdo_mysql.so"
10、之后再訪問還不行，還要修改數(shù)據(jù)庫結(jié)構(gòu)：
# mysql -u root -p
mysql> alter table npc_eventhandlers add long_output TEXT NOT NULL default '' after output;
mysql> alter table npc_hostchecks add long_output TEXT NOT NULL default '' after output;
mysql> alter table npc_hoststatus add long_output TEXT NOT NULL default '' after output;
mysql> alter table npc_notifications add long_output TEXT NOT NULL default '' after output;
mysql> alter table npc_servicechecks add long_output TEXT NOT NULL default '' after output;
mysql> alter table npc_servicestatus add long_output TEXT NOT NULL default '' after output;
mysql> alter table npc_statehistory add long_output TEXT NOT NULL default '' after output;
mysql> alter table npc_systemcommands add long_output TEXT NOT NULL default '' after output;
之后再訪問就可看到有數(shù)據(jù)了：
到此，cacti+nagios的整合就完事，搭建這個確實有好多問題，百度、谷歌才解決，希望能對有的人有幫助，如果有問題請及時指出，謝謝~
