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 tar zxf libart_lgpl-2.3.17.tar.gz

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
19.图形界面地址 http://192.168.1.18/nagios/pnp/index.php 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

##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
