9、被监控端安装

1、系统环境

[![wKioL1R20iCBNCoCAAC6g6ldheA468.jpg][]][wKioL1R20iCBNCoCAAC6g6ldheA468.jpg]

10、下载

\#wget[http://jaist.dl.sourceforge.net/project/nagios/nrpe-2.x/nrpe-2.14/nrpe-2.14.tar.gz][http_jaist.dl.sourceforge.net_project_nagios_nrpe-2.x_nrpe-2.14_nrpe-2.14.tar.gz] (nrpe插件)

11、创建用户

\#useradd nagios

\#passwd nagios

12、检查基础套件

\#rpm-q gcc glibc glibc-common gd gd-devel openssl-devel

13、安装nagios-plugins

\#./configure

\#make && make install

14、修改目录权限

15、安装nrpe

\#./configure

\#make all

\#make install-plugin  安装check\_nrpe

\#make install-daemon

\#make install-daemon-config

16、配置nrpe

\#vi /usr/local/nagios/etc/nrpe.cfg   添加  allowed\_hosts=192.168.40.128

17、启动nrpe

\#/usr/local/nagios/bin/nrpe  -c/usr/local/nagios/etc/nrpe.cfg -d

18、测试一下

\#/usr/local/nagios/libexec/check\_nrpe -H localhost

19、随机启动

\#echo "/usr/local/nagios/bin/nrpe  -c/usr/local/nagios/etc/nrpe.cfg -d" >> /etc/rc.local

20、配置

参考资料：[http://www.cnblogs.com/mchina/archive/2013/02/20/2883404.html][http_www.cnblogs.com_mchina_archive_2013_02_20_2883404.html]

至此nagios的服务端与客户端搭建完成

三、安装cacti

Cacti的运行需要LAMP（Linux+Apache + MySQL + PHP）, RRDTool ,net-snmp , AMP

正确配置各主机网络参数，本实验以一台机器既为服务端也为被监测端

\[root@localhost~\]\#vim/etc/sysconfig/network-scrip/ifcfg-eth0

在被监测端安装net-snmp软件包，net-snmp软件需要用到lm\_sensors提供的硬件监视模块，安装时直接使用RHEL5系统光盘中的rpm包文件，依次安装lm\_sensors、net-snmp两个软件包即可。

\[root@localhost~\]\# cd /mnt/Server/

\[root@localhostServer\]\# rpm -ivh lm\_sensors-2.10.0-3.1.i386.rpm

\[root@localhostServer\]\# rpm -ivh net-snmp-5.3.1-14.el5.i386.rpm

3、配置及启动snmpd服务，修改文件/etc/snmp/snmpd.conf第41、62、85行，设置SNMP访问权限

41行中将default修改为cacti监测服务器的IP地址本实验为192.168.4.1将public修改为共享SNMP信息的组识别字串publicsvr，62行 将systemview修改为all，85行去掉开头注释符号

41com2sec notConfigUser  192.168.4.1       publicsvr

62access  notConfigGroup ""      any      noauth    exact  all none none

iewall    included  .1                               80

4、启动snmpd服务并设置为自启动

\[root@localhostServer\]\# service snmpd start

启动 snmpd：                                              \[确定\]

\[root@localhostServer\]\# chkconfig --level 35 snmpd on

5、配置监测服务端

Cacti监测服务端需要有apache、mysql、php网站平台的支持，且需要预先安装有gd、zlib等软件包

httpd-2.2.3-6.el5

mysql-5.0.22-2.1

mysql-server-5.0.22-2.1

mysql-connector-odbc-3.51.12-2.2

php-5.1.6-5.el5

php-mysql-5.1.6-5.1.6-5.el5、

php-common-5.1.6-5.1.6-5.el5、php-pdo-5.1.6-5.el5

注：此处用源码包安装如下（也可用yum安装）

\[root@localhostServer\]\# rpm -ivh php-pdo-5.1.6-5.el5.i386.rpm

启动已安装好的httpd、mysqld服务，设置为每次开机随系统自动运行

\[root@localhost Server\]\# chkconfig --level35 mysqld on

\[root@localhostServer\]\# chkconfig --level 35 httpd on

6、安装net-snmp-utils软件包

\[root@localhostServer\]\# rpm -ivh net-snmp-utils-5.3.1-14.el5.i386.rpm

warning:net-snmp-utils-5.3.1-14.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID37017186

\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\[100%\]

7、安装rrdtool软件包

\[root@localhost ~\]\# mount /dev/cdrom /mnt

mount:block device /dev/cdrom is write-protected, mounting read-only

\[root@localhost~\]\# cd /mnt/Linux-gateway/LGS-SG6

\[      root@localhost LGS-SG6\]\# tar zxvfrrdtool-1.2.27.tar.gz

\[root@localhost src\]\# cd rrdtool-1.2.27/

\[root@localhost rrdtool-1.2.27\]\#./configure --prefix=/usr/local

\[root@localhost rrdtool-1.2.27\]\# nake&& make install

8、安装cacti文件包

\[root@localhost html\]\# cd /var/www/html

\[root@localhost html\]\# tar zxvf/mnt/Linux-gateway/LGS-SG6/cacti-0.8.7b-cn-utf8.tar.gz

\[root@localhosthtml\]\# mv cacti-0.8.7b-cn-utf8 cacti

\[root@localhosthtml\]\# useradd cactiuser

\[root@localhosthtml\]\# chown -R cactiuser.cactiuser cacti/rra/ cacti/log/

9、设置监测数据库、表，设置好授权访问数据库的用户和密码

\[root@localhosthtml\]\# mysql -u root -p

Enterpassword:

Welcometo the MySQL monitor.  Commands end with; or \\g.

YourMySQL connection id is 2 to server version: 5.0.22

Type'help;' or '\\h' for help. Type '\\c' to clear the buffer.

mysql>create database cactidb default character set utf8;

QueryOK, 1 row affected (0.00 sec)

mysql>grant all on cactidb.\* to cactiuser@localhost identified by 'pwd@123';

QueryOK, 0 rows affected (0.02 sec)

mysql>

\[root@localhosthtml\]\# mysql -u cactiuser -p cactidb < cacti/cacti.sql

Enterpassword

10、调整cacti配置文件

\[root@localhosthtml\]\# cd /var/www/html/cacti/

\[root@localhostcacti\]\# vim include/config.php

$database\_type= "mysql";

$database\_default= "cactidb";

$database\_hostname= "localhost";

$database\_username= "cactiuser";

$database\_password= "pwd@123";

$database\_port= "3306";

$config\['url\_path'\]="/"

11、调整httpd设置并重新启动服务

DocumentRoot"/var/www/html/cacti"

<Directory"/var/www/html/cacti>

Options FollowSymLinks

AllowOverride None

</Directory>

<Directory"/var/www/html/cacti">

Options None

AllowOverride None

Orderallow,deny

Allowfrom all

</DirectoryOA>

DirectoryIndexindex.html index.php index.html.var//设置默认索引页

12、初始化cacti系统

[![wKioL1R20j-DlB43AAGZ1r2rgB0029.jpg][]][wKioL1R20j-DlB43AAGZ1r2rgB0029.jpg]

为了在监测图像中正常显示中文，还需要设置RRDtool所使用的中文字体路径。同样通过左侧栏中的“设置”链接，找到路径选项卡中的“RRDtool默认字体路径”将字体路径设置为“/usr/share/fonts/zh\_CN/TureType/zysong.ttl”点击右下方的“保存”即可。

整合cacti和nagios

整合cacti和nagios是利用了cacti的一个插件nagios for cacti，它的原理是将nagios的数据通过ndo2db导入到mysql数据库（cacti的库中），然后cacti读取数据库信息将nagios的结果展示出来

（1）、安装ndoutils

首先需要安装ndoutils以将nagios的数据能导入到mysql数据库中。

yum-y install mysql-devel    安装mysql开发包以编译ndoutils

前提：因为本次安装nagios用的是4.0的版本，所以要安装2.0以上的ndoutils不然会显示加载模块不成功

tar-zcvf ndoutils-2.0.0.tar.gz

cdndoutils-2.0.0

./configure--prefix=/usr/local/nagios/ --with-mysql-inc=/usr/include/mysql--with-mysql-lib=/usr/lib/mysql --enable-mysql --disable-pgsql--with-ndo2db-user=nagios --with-ndo2db-group=nagios

Make

makeinstall

cp-v \{ndomod-4x.o,ndo2db-4x,file2sock,log2ndo\} /usr/local/nagios/bin

./installdb-ucactiuser -ppwd@123 -d cactidb

cpndomod.cfg-sample /usr/local/nagios/etc/ndomod.cfg

修改nagios主配置文件  
\#vi /usr/local/nagios/etc/nagios.cfg

10、添加以下内容  
check\_external\_commands=1

command\_check\_interval=-1

event\_broker\_options=-1

broker\_module=/usr/local/nagios/bin/ndomod.oconfig\_file=/usr/local/nagios/etc/ndomod.cfg

process\_performance\_data=1

添加的内容至此结束

11、修改配置文件ndocmd.cfg和ndo2db.cfg，这里我的配置文件内容为：  
\[root@localhost downloads\]\# cat /usr/local/nagios/etc/ndomod.cfg |grep -v'^\#'|sed /^$/d

instance\_name=default

output\_type=tcpsocket

output=127.0.0.1

tcp\_port=5668

output\_buffer\_items=5000

buffer\_file=/usr/local/nagios/var/ndomod.tmp

file\_rotation\_interval=14400

file\_rotation\_timeout=60

reconnect\_interval=15

reconnect\_warning\_interval=15

data\_processing\_options=-1

config\_output\_options=2

\[root@localhostdownloads\]\# cat /usr/local/nagios/etc/ndo2db.cfg |grep -v '^\#'|sed /^$/d

ndo2db\_user=nagios

ndo2db\_group=nagios

socket\_type=tcp

socket\_name=/usr/local/nagios/var/ndo.sock

tcp\_port=5668

db\_servertype=mysql

db\_host=127.0.0.1

db\_port=3306

db\_name=cacti

db\_prefix=npc\_

db\_user=cacti

db\_pass=cacti2008

max\_timedevents\_age=1440

max\_systemcommands\_age=10080

max\_servicechecks\_age=10080

max\_hostchecks\_age=10080

max\_eventhandlers\_age=44640

debug\_level=1

debug\_verbosity=1

debug\_file=/usr/local/nagios/var/ndo2db.debug

max\_debug\_file\_size=1000000  
12、\#/usr/local/nagios/bin/ndo2db-c /usr/local/nagios/etc/ndo2db.cfg    启动ndo2db

（2）、安装安装php-json  npc展示部分用到json，需要在php中安装php-json的支持

Yuminstall php-devel    否则，phpsize命令不好用

\#wgethttp://www.aurore.net/projects/php-json/php-json-ext-1.2.0.tar.bz2

\#tarxvjf  php-json-ext-1.2.0.tar.bz2

\#cdphp-json-ext-1.2.0

\#phpize            编译前初始化php环境

\#./configure

\#make

\#makeinstall

\#vi/etc/php.d/json.ini  
extension=php\_json.so

\#cp/usr/lib/php/modules/json.so /usr/lib/php/modules/php\_json.so  这一步骤很关键，因为，apache否则日志报错加载不到php\_json.so文件。

\#/usr/sbin/httpd-k graceful    重启apache

为了验证是否成功可使用phpinfo查看是否已支持json

（3）安装npc

wget[http://www.assembla.com/spaces/npc/documents/aUjAwmdW8r3BuPab7jnrAJ/download?filename=npc-2.0.0b.166.tar.gz][http_www.assembla.com_spaces_npc_documents_aUjAwmdW8r3BuPab7jnrAJ_download_filename_npc-2.0.0b.166.tar.gz]

wget   http://dlwt.csdn.net/fd.php?i=659714146741849&s=796b68562511c6534bfc15d7b04711f4/npc-2.0.3.tar.gz  新链接可用  
\#mv npc /usr/local/wwwroot/cacti/plugins/  
启用cacti的插件功能，以admin用户登陆cacti，在console中的usermanagement里对admin的用户权限进行编辑，勾选上PluginManagement，然后到插件管理中心安装并启用NPC即可。

在'User Management'中选择'admin',在下边'Realm Permissions'中钩选'Plugin Management'。这时右侧会出现'Plugin Management'连接，进去后在'uninstalled'中安装npc，然后在'intalled'中enablenpc,然后在回去admin的'RealmPermissions'中会出现'use npc'，如果没有钩选就把它选中。

接着在右侧栏目中选择settings,点选npc的标签

钩选Remote Commands

NagiosCommand File Path：     /usr/local/nagios/var/rw/nagiosNaNd

<这个文件启动nagios后会产生，根据实际的位置写>

NagiosURL：     [\[url\]http://yourserver/nagios/\[/url\]][url_http_yourserver_nagios_url]

保存就可以了。

至此安装就完成了

启动mysql httpd ndo nagios

servicemysqld start

servicehttpd start

/usr/local/nagios/bin/ndo2db-c /usr/local/nagios/etc/ndo2db.cfg

servicenagios start

访问[\[url\]http://yourserver/cacti/\[/url\]][url_http_yourserver_cacti_url]

（4）测试页面

在IE浏览器的地址栏输入：[http://192.168.30.162/cacti][http_192.168.30.162_cacti]

用户名：admin      密码：admin

第一次登录的时候，会提示修改管理员密码，按照提示修改即可。

查看npc是否显示

[![wKioL1R20v7BoccHAALiUjM3Qks555.jpg][]][wKioL1R20v7BoccHAALiUjM3Qks555.jpg]

（5）正常显示

[![wKioL1R20yOg313NAAcM9DutQuE364.jpg][]][wKioL1R20yOg313NAAcM9DutQuE364.jpg]

[![wKiom1R20vyhO9gkAAcTSYt7tFo062.jpg][]][wKiom1R20vyhO9gkAAcTSYt7tFo062.jpg]

报错解决

A、安装完成npc之后无法显示页面，最终找到解决办法是因为php的扩展不支持

解决如下

安装前准备  
yum -y install php-devel php-pear gcc make  
  
2.安装json  
pear install pecl/json  
或者  
pecl install json  
  
3.让php支持json  
我的php是yum安装的,所以  
cd /etc/php.d  
echo "extension=json.so" > json.ini  
重启apache  
service httpd restart  
  
如果有selinux,执行下面命令  
chcon system\_u:object\_r:textrel\_shlib\_t /usr/lib/php/modules/json.so  
或  
chcon -c -v -R -u system\_u -r object\_r -t textrel\_shlib\_t/usr/lib/php/modules/json.so  
  
4.验证  
php -m|grep json  
json  
可以看到php已经支持json了,现在可以重新去执行了php页面了.

B、页面显示之后，可惜的是nagios显示off的状态，找各种办法，是ndoutils的版本问题，重新安装即可，至此可正常显示
