NAGIOS+CACTI服务器安装

NAGIOS+CACTI服务器安装

Nagios服务端安装

============================

1.解决perl插件编译安装问题

echo 'export LC_ALL=C' >> /etc/profile

source /etc/profile

echo $LC_ALL

2.安装必须软件

yum -y install gcc glibc glibc-common gd  gd-devel httpd php* mysql*

3.添加nagios和httpd用户

/usr/sbin/useradd nagios

/usr/sbin/groupadd nagcmd

/usr/sbin/usermod -a -G nagcmd nagios  
/usr/sbin/usermod -a -G nagcmd apache    
groups nagios    
groups apache

4.启动lamp服务

vim /etc/httpd/conf/httpd.conf +402

/etc/init.d/httpd start

chkconfig httpd --level 3 on

vim /etc/httpd/conf/httpd.conf  +276

#注意修改ServerName 127.0.0.1:80避免apache启动报错

5.编译安装nagios

cd /soft

wget http://soft.local.com/nagios-3.5.1.tar.gz

tar zxf nagios-3.5.1.tar.gz

cd nagios

./configure --with-command-group=nagcmd

make all

make install

make install-init  
make install-commandmode    
make install-config

6.安装nagios的web配置文件和建立登录用户

cd /soft/nagios  
make install-webconf

#在nagios的软件解压目录里面执行

7.修改nagios的登录密码

htpasswd -cb /usr/local/nagios/etc/htpasswd.users yjb007 123456

8.启用sendmail服务

yum -y install sendmail  
/etc/init.d/sendmail start    
chkconfig sendmail --level 3 on

9.安装nagios服务端插件

yum -y install perl-CPAN

cd /soft

wget http://soft.local.com/nagios-plugins-1.4.16.tar.gz

tar zxf nagios-plugins-1.4.16.tar.gz  
cd nagios-plugins-1.4.16

./configure --with-nagios-user=nagios --with-nagios-group=nagios --enable-perl-modules

make

make install

10.开机启动nagios

chkconfig --level 3 nagios on

11.检查nagios的配置文件语法

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

/etc/init.d/nagios checkconfig

vim /etc/init.d/nagios +177

12.启动nagios

/etc/init.d/nagios start

ps -ef | grep nagios

13.服务端安装nrpe，因为nagios是主动查询报警

cd /soft

wget http://soft.local.com/nrpe-2.12.tar.gz

tar zxf nrpe-2.12.tar.gz  
cd nrpe-2.12    
./configure    
make all    
make install-plugin    
make install-daemon    
make install-daemon-config    
ll /usr/local/nagios/libexec/check_nrpe

14.配置nagios.cfg

-------------------------------------

vim /usr/local/nagios/etc/nagios.cfg +34

cfg_dir=/usr/local/nagios/etc/objects/services

#目录下面的.cfg文件全部生效

#注释掉所有cfg_file=

15.修改vim ../cgi.cfg

sed -i s#nagiosadmin#yjb007#g /usr/local/nagios/etc/cgi.cfg

16.重载nagios

/etc/init.d/nagios reload

17.Nagios出图配置：PNP出图  -服务器端

---------------------------------------------

yum -y install zlib zlib-devel freetype freetype-devel gd gd-devel cairo pango

cd /soft

wget http://soft.local.com/libart_lgpl-2.3.17.tar.gz

cd libart_lgpl-2.3.17    
./configure    
make    
make install    
/bin/cp -r /usr/local/include/libart-2.0/ /usr/include/

cd /soft

wget http://soft.local.com/rrdtool-1.2.14.tar.gz

tar zxf rrdtool-1.2.14.tar.gz

cd rrdtool-1.2.14

./configure --prefix=/usr/local/rrdtool --disable-python --disable-tcl

make

make install

ll /usr/local/rrdtool/bin/

cd pnp-0.4.14

./configure  --with-rrdtool=/usr/local/rrdtool/bin/rrdtool --with-perfdata=/usr/local/nagios/share/perfdata

make all  
make install    
make install-config    
make install-init

#检测安装成功与否，出图数据脚本，安装完毕

ll /usr/local/nagios/libexec/process_perfdata.pl

18.配置nagios出图配置

--------------------------------------------

vim /usr/local/nagios/etc/nagios.cfg +831

process_performance_data=1

#修改成1，存储监控数据

host_perfdata_command=process-host-perfdata  
service_perfdata_command=process-service-perfdata

#将这两行取消注释

CACTI安装配置

----------------------------------------------------------

客户端安装snmp

1.yum -y install net-snmp*

ll /etc/snmp/snmpd.conf

2.默认配置文件

cat >/etc/snmp/snmpd.conf <<EOF

com2sec local     localhost      public  
com2sec mynetwork  10.0.0.0/24   public    
group MyRWGroup v1         local    
group MyRWGroup v2c        local    
group MyRWGroup usm        local    
group MyROGroup v1         mynetwork

EOF

##cat >/etc/snmp/snmpd.conf <<EOF是先”cat >/etc/snmp/snmpd.conf“清空

##然后/etc/snmp/snmpd.conf <<EOF追加

3./etc/init.d/snmpd start

#启动snmp,TCP:161

服务器端的安装

1.安装libart_lgpl-2.3.17.tar.gz

unzip cacti_tools.tar.gz  
tar zxf cacti_tools.tar.gz    
cd cacti_tools    
tar zxf libart_lgpl-2.3.17.tar.gz

./configure  
make    
make install    
/bin/cp -r /usr/local/include/libart-2.0 /usr/include/

2.安装rrdtool

tar zxvf cgilib-0.5.tar.gz  
cd cgilib-0.5    
make    
cp libcgi.a /usr/local/lib    
cp cgi.h /usr/include

yum -y install pango-devel* cairo-devel* gcc glibc glibc-common cairo pango zlib zlib-devel freetype \

freetype-devel gd gd-devel libart_lgpl-devel

cd /root/cacti_tools/rrdtool-1.2.30

./configure

make  
make install

ln -s /usr/local/rrdtool-1.2.30/bin/rrdtool /usr/local/bin/rrdtool

4.安装配置一些必要软件

yum -y install mysql* httpd* php*

#若报错，则加参数--skip-broken

vim /etc/httpd/conf/httpd.conf  +276

vim /etc/httpd/conf/httpd.conf  +402

egrep "127.0.0.1|index.php" /etc/httpd/conf/httpd.conf

#修改httpd的默认配置文件，增加主机解析和默认首页index.php

echo  -e "<?php \nphpinfo();\n?>" > /var/www/html/index.php

#建立php测试文件

5.启动数据库

/etc/init.d/mysqld start

6.建立cacti用的数据库账号

mysql> grant all on cacti.* to cactiuser@localhost identified by "cactiuser";

mysql> flush privileges;

mysql> create database cacti;

mysql> select user,host from mysql.user;

##CACTI软件的配置密码默认是cactiuser

7.安装CACTI

cd /root/cacti_tools/cacti-0.8.8a

tar zxf cacti-0.8.8a.tar.gz  
cd cacti-0.8.8a

mysql cacti < cacti.sql

#将 cacti.sql 恢复到数据库了， cacti.sql 在cacti安装里带的

8.修改cacti连接数据库的配置文件，26-32行

[root@C05 cacti-0.8.8a]# vim include/config.php +26

9.授权apache对CACTI目录下的log/ rra/有权限

chown -R apache log/ rra/

10.将cacti的整个目录拷贝到网站目录下

/bin/mv ../cacti-0.8.8a /var/www/html/cacti  
ll /var/www/html/cacti/

cd /var/www/html/cacti/  
chown -R apache.apache /var/www/html/cacti

11.测试定时收集数据poller.php工作正常并加入到定时任务

setenforce 0

chmod 755 /var/www/html/cacti/poller.php

/usr/sbin/ntpdate pool.ntp.org

/usr/bin/php /var/www/html/cacti/poller.php

echo "*/5 * * * * /usr/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&1" >> /var/spool/cron/root

crontab -l

12.web页面开始配置cacti

http://192.168.1.15/cacti

#注意RRDTOOl版本和snmp版本

默认用户名和密码是admin/admin

13.配置

---------------------

|-- cacti_graph_template_snmp_get_netstat_connection_oldboytrainning.xml  
|-- get_netstat_tcp_oldboytrainning.pl

----------------------

#一个脚本应该包括两个文件

#XML脚本通过perl调用.pl脚本

perl get_netstat_tcp_oldboytrainning.pl 192.168.1.16 2c public 161 500

#手动测试看能否出数据

#导入模板
