passwd nagios

groupadd nagcmd
usermod -G nagcmd nagios
usermod -G nagcmd apache

安装软件

tar zxvf nagios-3.2.3.tar.gz

cd nagios-3.2.3

./configure --prefix=/usr/local/nagios --with-command-group=nagcmd && make all && make install && make install-init && make install-config && make install-commandmode && make install-webconf

cd ..

tar xvf nagios-plugins-1.4.15.tar.gz

cd nagios-plugins-1.4.15

./configure --with-nagios-user=nagios --with-nagios-group=nagios && make && make install && cd ..

tar xvf nagios-cn-3.2.3.tar.bz2

cd nagios-cn-3.2.3

./configure && make all && make install && cd ..

#配置一个nagiosadmin用户，用于nagios的web管理接口登录
htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin

#验证nagios.cfg文件是否有错，建议每次修改配置文件后都验证一下，确认无误后重启nagios服务
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

#关闭selinux
vi /etc/selinux/config
将'SELINUX=enforcing'改成'SELINUX=disabled'
setenforce 0

#启动apache服务，并设置为开机启动
service httpd start
chkconfig httpd on

#启动nagios服务，并设置为开机启动
service nagios start
chkconfig nagios on

#检查开启情况
ps -ef  //检查进程
访问：http://10.2.0.250/nagios/，输入用户名密码，便可打开nagios的web管理接口

至此，主监控服务器上的nagios配置完毕。

#配置邮件报警功能

1、安装sendmail服务
yum install -y sendmail*

2、开启服务，并设置为开机启动
service sendmail start
chkconfig sendmail on

3、设置sendmail邮件接收和转发功能
vi /etc/mail/access
添加如下内容：
Connect:http://www.163.com               RELAY
Connect:[email protected]    RELAY
Connect:root@localhost                       RELAY
:wq

makemap -v hash /etc/mail/access.db < /etc/mail/access

4、更改mqueue权限
chmod 777 /var/spool/mqueue

5、检查所传送的电子邮件是否送出，或滞留在邮件服务器中
/usr/lib/sendmail -bp
若屏幕显示为“Mail queue is empty” 的信息，表示mail 已送出

6、发送邮件进行检查
echo testing | /usr/sbin/sendmail -v [email protected]

#设置联系人邮件通知,在系统有故障时通过邮件告知管理员

vi /usr/local/nagios/etc/objects/contacts.cfg
注释掉原来的define contact，并添加如下内容：
define  contact{
        contact_name                    yang_ang0219
        use                             generic-contact
        alias                           nagios admin    
        service_notification_commands   notify-service-by-email
        host_notification_commands      notify-host-by-email
        email                           [email protected]
        ｝
并修改联系人组，修改成如下内容：
define contactgroup{
        contactgroup_name       admins
        alias                   Nagios Administrators
        members                 yang_ang0219
        }

#安装pnp4nagios 输出图形和图表(需要php5.2以上的版本)

http://www.360doc.com/content/11/0810/11/1208969_139346861.shtml
安装pnp4nagios-0.6.7
tar zxvf pnp4nagios-0.6.7.tar.gz
cd pnp4nagios-0.6.7
./configure --with-nagios-user=nagios --with-nagios-group=nagcmd&& make all &&make install &&make install-webconf &&make install-config &&make install-init &&cd ..

4、修改配置
cd /usr/local/pnp4nagios/etc
cp misccommands.cfg-sample misccommands.cfg
cp nagios.cfg-sample nagios.cfg
cp npcd.cfg-sample npcd.cfg
cp process_perfdata.cfg-sample process_perfdata.cfg
cp rra.cfg-sample rra.cfg

cd pages
cp web_traffic.cfg-sample web_traffic.cfg

cd ../check_commands
cp check_all_local_disks.cfg-sample check_all_local_disks.cfg
cp check_nrpe.cfg-sample check_nrpe.cfg
cp check_nwstat.cfg-sample check_nwstat.cfg

5、启动npcd服务并设置为开机启动
service npcd start

chkconfig npcd on

6、修改nagios.cfg文件
cd /usr/local/nagios/etc
vi nagios.cfg
修改配置如下：
process_performance_data=1
host_perfdata_command=process-host-perfdata
service_perfdata_command=process-service-perfdata
:wq

7、修改commands.cfg文件
cd /usr/local/nagios/etc/objects
vi commands.cfg
修改process-host-perfdata和process-service-perfdata为：
#'process-host-perfdata' command definitio
define command{
        command_name    process-host-perfdata
        command_line    /usr/bin/perl /usr/local/pnp4nagios/libexec/process_perfdata.pl -d HOSTPERFDATA
           ｝

#'process-service-perfdata' command definition
define command{
        command_name    process-service-perfdata
        command_line    /usr/bin/perl /usr/local/pnp4nagios/libexec/process_perfdata.pl
        }
:wq

8、修改模板，添加小太阳镶嵌在nagios页面上
vi templates.cfg
在最后添加：
define host{
     name       host-pnp
     action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=_HOST_
     register   0
         }

define service{
     name       srv-pnp
     action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$
     register   0
           }
:wq

9、修改主机配置文件：

[root@localhost ~]# cat /usr/local/nagios/etc/objects/localhost.cfg |grep -v "#"  |sed /^$/d
define host{
        use                     linux-server,host-pnp            ; Name of host template to use
                                                        ; This host definition will inherit all variables that are defined
                                                        ; in (or inherited by) the linux-server host template definition.
        host_name               localhost
        alias                   localhost
        address                 127.0.0.1
        }
define hostgroup{
        hostgroup_name  linux-servers ; The name of the hostgroup
        alias           Linux Servers ; Long name of the group
        members         localhost     ; Comma separated list of hosts that belong to this group
        }
define service{
        use                             local-service,srv-pnp        ; Name of service template to use
        host_name                       localhost
        service_description             PING
        check_command                   check_ping!100.0,20%!500.0,60%
        }
define service{
        use                             local-service,srv-pnp         ; Name of service template to use
        host_name                       localhost
        service_description             Root Partition
        check_command                   check_local_disk!20%!10%!/
        }
define service{
        use                             local-service,srv-pnp         ; Name of service template to use
        host_name                       localhost
        service_description             Current Users
        check_command                   check_local_users!20!50
        }
define service{
        use                             local-service,srv-pnp         ; Name of service template to use
        host_name                       localhost
        service_description             Total Processes
        check_command                   check_local_procs!250!400!RSZDT
        }
define service{
        use                             local-service,srv-pnp         ; Name of service template to use
        host_name                       localhost
        service_description             Current Load
        check_command                   check_local_load!5.0,4.0,3.0!10.0,6.0,4.0
        }
define service{
        use                             local-service,srv-pnp         ; Name of service template to use
        host_name                       localhost
        service_description             Swap Usage
        check_command                   check_local_swap!20!10
        }
define service{
        use                             local-service,srv-pnp         ; Name of service template to use
        host_name                       localhost
        service_description             SSH
        check_command                   check_ssh
        notifications_enabled           0
        }
define service{
        use                             local-service,srv-pnp        ; Name of service template to use
        host_name                       localhost
        service_description             HTTP
        check_command                   check_http
        notifications_enabled           0
        }

10、删除instal.php
cd /usr/local/pnp4nagios/share
rm -f install.php

11、验证配置文件
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

12、无误后重启nagios和httpd 服务
service nagios restart
service httpd restart

最后登录nagios控制台，选择host--主机名旁边的小太阳，即可看到图形界面！大功告成！

 

 

 

 

好的至此  nagios监控端安装软件完成

下面安装cacti 

cacti 是基于snmp的 

所以配置安装snmp（net-snmp）

vim /etc/snmp/snmpd.conf  修改如下：

 

 

 

 

 

重启snmp服务器

/etc/init.d/snmpd restart

chkconfig snmpd on

tar zxvf cacti-0.8.7e.tar.gz

mv cacti-0.8.7e /var/www/html/cacti

修改cacti连接数据库的配置文件 

vim /var/www/html/cacti/include/config.php

 

 好的 我们需要创建一个cacti数据库设置密码 给予权限

>create database cacti;

>grant all privileges on cacti.* to cacti@localhost identified by 'cacti' with grant option;

>grant all privileges on cacti.* to [email protected] identified by 'cacti' with grant option;

>use cacti;

>source /var/www/html/cacti/cacti.sql;

>exit

然后登陆网页 http://IP/cacti   请安装提示操作

添加计划任务

*/5 * * * * /usr/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&1

如果想立即cacti绘图的话 请直接执行：

/usr/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&1

然后刷新页面 稍等会 就看到绘图了

整合cacti+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

tar xvf ndoutils-1.4b7.tar.gz 

cd ndoutils-1.4b7

./configure --with-mysql-lib=/usr/lib/mysql/ --with-mysql-inc=/usr/include/mysql/

make

cd src/

cp ndomod-3x.o /usr/local/nagios/bin/.

cd ndo2db-3x /usr/local/nagios/bin/ndo2db

cd ../config

cp ndo2db.cfg /usr/local/nagios/etc/

cp ndomod.cfg /usr/local/nagios/etc/

cd /usr/local/nagios/etc/

chown nagios:nagios ndo2db.cfg ndomod.cfg

cd ../bin/

chown nagios:nagios ndo2db ndomod-3x.o

 

然后修改ndo2db.cfg  ndomod.cfg的配置文件

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=cactiuer
db_pass=cactiuser
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

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

然后再编辑nagios的主配置文件 nagios.cfg 在最后添加如下：

check_external_commands=1
command_check_interval=-1
event_broker_options=-1
process_performance_data=1
broker_module=/usr/local/nagios/bin/ndomod-3x.o config_file=/usr/local/nagios/etc/ndomod.cfg

保存退出

启动ndo

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

echo "/usr/local/nagios/bin/ndo2db -c /usr/local/nagios/etc/ndo2db.cfg" >>/etc/rc.local

service nagios restart

service httpd restart

2.安装php-json

tar xvf php-json-ext-1.2.0.tar.bz2

cd php-json-ext-1.2.0

首先初始化php(如果没有这个命令  请 yum install php-devel)

phpize

./configure

make 

make install

查看是否安装成功
find / -name *json.so

vim /etc/php.ini

查找到include 在旗下添加如下语句：

include ('/etc/php.d/json.ini')

vim /etc/php.d/json.ini

内容如下：

extension=json.so

重启web服务

/etc/init.d/httpd restart

安装cacti的插件管理器 （cacti插件使用的前提 需要和cacti主程序版本一致）

unzip cacti-plugin-0.8.7e-PA-v2.5.zip -d cacti-plugin

cp -R cacti-plugin/* /var/www/html/cacti/

cd /var/www/html/cacti/

mysql -uroot cacti < pa.sql (这里因为我没有设置mysql数据库的密码 所以没有-p选项 设置mysql密码 : mysqladmin -uroot -p password mysql)

patch -p1 -N < cacti-plugin-0.8.7e-PA-v2.5.diff

 

vim include/global.php (修改如下 )：

 

这是连接数据库方面的设置

 

 

 

重启httpd服务

cacti的插件 安装完成 。

3.npc插件的安装

tar zxvf npc-2.0.4.tar.gz

mv npc /var/www/html/cacti/plugins/.

 

vim /var/www/html/cacti/include/global.php 修改如下：（这是为了让npc插件在管理里面看到）

 

保存退出
重启httpd服务

重启nagios服务

 

然后呢 只需要去cacti的web页面上 设置下即可：如图

 

 

 

 

 

 

 

好的 至此 cacti和nagios的整合成功 

不足之处 请大牛指出来 并给以相关的资料 谢谢
