nagios+pnp4nagios配置
一、安装pnp4nagios官方的安装文档（http://docs.pnp4nagios.org/pnp-0.6/doc_complete）
1、安装
# wget http://jaist.dl.sourceforge.net/ ...agios-0.6.22.tar.gz
# tar xzvf pnp4nagios-0.6.22.tar.gz
#yum install -yperl-Time-HiRes
（编译时可能会报错，请安装上面的perl包）
# ./configure\--prefix=/usr/local/pnp4nagios--with-nagios-user=nagios--with-nagios-group=nagios \--with-nagios-group=nagios--with-rrdtool=/usr/local/rrdtool/bin/rrdtool //rrdtool为源码安装# make all
# make fullinstall
2、修改nagios.cfg
# vim /usr/local/nagios/etc/nagios.cfg
修改如下
process_performance_data=1
service_perfdata_command=process-service-perfdata
host_perfdata_command=process-host-perfdata
3、修改nagios command配置文件
# cd /usr/local/nagios/etc/objects
# vim commands.cfg
(在文件末尾追加如下几行,删除原来的)
definecommand {
command_name process-service-perfdata
command_line /usr/bin/perl/usr/local/pnp4nagios/libexec/process_perfdata.pl
}
definecommand {
command_name process-host-perfdata
command_line /usr/bin/perl/usr/local/pnp4nagios/libexec/process_perfdata.pl -d HOSTPERFDATA
}
4、修改nagios template 配置文件
# vim /usr/local/nagios/etc/objects/templates.cfg
(在文件末尾追加如下几行)
definehost {
name host-pnp
action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=_HOST_
register 0
}
defineservice {
name service-pnp
action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$
register 0
}
5、修改 hosts.cfg 和 services.cfg
这两个文件默认是不存在的，从localhost.cfg文件中复制，是用来定义你要监控的主机和服务，需要你手工创建。
# vim hosts.cfg
definehost{
use linux-server,host-pnp
host_name web01
alias pub_web01
address 192.168.0.51
}
definehost{
use linux-server,host-pnp
host_name oracle
alias pub_oracle
address 192.168.0.180
}
# vim services.cfg
#####################pubweb01 #####################
defineservice{
use local-service,service-pnp
host_name web01
service_description PING
check_command check_ping!100.0,20%!500.0,60%
}
defineservice{
use local-service,service-pnp
host_name web01
service_description SSH
check_command check_ssh
}
defineservice{
use local-service,service-pnp
host_name web01
service_description http
check_command check_http
}
测试nagios配置文件是否正确
#/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
6、apache与pnp整合
pnp4nagios4.10版本apache至此不需要做任何配置，直接就可以访问了，升级到0.6后发现必须rewrite了
安装pnp4nagios时使用make install-webconf
这个会在/etc/httpd/conf.d/中生成pnp4nagios.conf文件将其复制到http.conf文件中
vim /etc/httpd/conf/httpd.conf
最后空白处添加：1.Alias /pnp4nagios "/usr/local/pnp4nagios/share" 2. 3.<Directory "/usr/local/pnp4nagios/share"> 4. AllowOverride None 5. Order allow,deny 6. Allow from all 7. AuthName "Nagios Access" 8. AuthType Basic 9. AuthUserFile /usr/local/nagios/etc/htpasswd //根据自身路径设置10. Require valid-user 11. <IfModule mod_rewrite.c> 12. RewriteEngine On 13. Options FollowSymLinks 14. RewriteBase /pnp4nagios/ 15. RewriteRule ^(application|modules|system) - 16. RewriteCond %{REQUEST_FILENAME} !-f 17. RewriteCond %{REQUEST_FILENAME} !-d 18. RewriteRule .* index.php/$0 19. </IfModule> 20.</Directory>
7、创建nagios登录web用户
# htpasswd -c /usr/local/nagios/etc/htpasswdnagiosadmin
8、修改php目录权限，让apache支持pnp
# chown -R apache.apache /var/lib/php/
9、删除install.php文件
# rm -f /usr/local/pnp4nagios/share/install.php
10、重新加载启动项
# /etc/init.d/httpd reload# /etc/init.d/nagios reload
查看/usr/local/pnp4nagios/var/perfdata有没有数据
错误一：
访问http://192.168.212.130/pnp4nagios
解决办法：将/usr/local/pnp4nagios/share中的install.php 删除即可
错误二：
解决方案：默认的php是root的组，而我的httpd.conf配置文件中http的用户和组是apache所以将php权限改为apache即可
1.cd /var/lib2.chown -R apache.apache php/
