cacti nagios npc整合配置

centos5.5 + cacti + nagios + npc
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)

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、導入數據庫
# mysql -u root -p cacti < cacti/cacti.sql  
Enter password:

5、修改cacti配置文件,連接數據庫
# 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、打補丁導入數據庫
# 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
# crontab -e  
*/5 * * * * /usr/bin/php /var/www/html/cacti/poller.php  
# service crond restart 

10、浏覽器輸入http://192.168.163.143/cacti/install初始化cacti,最後如下:

另外cacti無法顯示圖片,圖片顯紅叉,但是點進去有圖:
解決方法:
settings裡面的RRDTOOLS版本設置不對,默認為1.0.x,改為1.2.x就行了。


 

三、被監控端配置
 
1、安裝snmp服務
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:(這裡我省略掉了#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
service snmpd restart

到此就差不多了,我們可以做些檢測在服務器上,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  
 
最後添加如下內容,設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/Linux/1727.html' target='_blank'>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 //監控那個主機,host-142在hosts.cfg中定義  
 service_description ssh //對監控內容的描述  
 check_command check_ssh //指定監控的命令,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以後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的數據通過ndo2db導入到mysql數據庫(cacti的庫中),然後cacti讀取數據庫信息將nagios

的結果展示出來。

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

安裝完成後如果先驗證的話,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前面已經裝過這裡就不用再裝了

# 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、修復配置文件信息,連接數據庫
# 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,並修改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

啟動之後在cacti中添加npc,如下:


當訪問到npc這個頁面的時候已經擦不多了

9、但是看npc裡發現空白的,沒有數據,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,之後重啟httpd即可  
extension = "pdo_mysql.so" 

10、之後再訪問還不行,還要修改數據庫結構:

# 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; 

之後再訪問就可看到有數據了:
