6.创建二进制命令,CGI,html文件
[root@testvm02 nagios-4.4.1]# make install
7.安装相关的进程文件(安装启动脚本),增加httpd开机启动,nagios开机启动
[root@testvm02 nagios-4.4.1]# make install-daemoninit /usr/bin/install -c -m 755 -d -o root -g root /etc/init.d /usr/bin/install -c -m 755 -o root -g root startup/default-init /etc/init.d/nagios *** Init script installed ***
[root@testvm02 nagios-4.4.1]# chkconfig --level 2345 httpd on
[root@testvm02 nagios-4.4.1]# chkconfig --list | grep httpd
httpd 0:off 1:off 2:on 3:on 4:on 5:on 6:off
[root@testvm02 nagios-4.4.1]# chkconfig --list | grep nagios
nagios 0:off 1:off 2:on 3:on 4:on 5:on 6:off
8.安装外部命令文件
[root@testvm02 nagios-4.4.1]# make install-commandmode
/usr/bin/install -c -m 775 -o nagios -g nagios -d /usr/local/nagios/var/rw
chmod g+s /usr/local/nagios/var/rw
*** External command directory configured ***
9.安装配置文件
[root@testvm02 nagios-4.4.1]# make install-config /usr/bin/install -c -m 775 -o nagios -g nagios -d /usr/local/nagios/etc /usr/bin/install -c -m 775 -o nagios -g nagios -d /usr/local/nagios/etc/objects /usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/nagios.cfg /usr/local/nagios/etc/nagios.cfg /usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/cgi.cfg /usr/local/nagios/etc/cgi.cfg /usr/bin/install -c -b -m 660 -o nagios -g nagios sample-config/resource.cfg /usr/local/nagios/etc/resource.cfg /usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/templates.cfg /usr/local/nagios/etc/objects/templates.cfg /usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/commands.cfg /usr/local/nagios/etc/objects/commands.cfg /usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/contacts.cfg /usr/local/nagios/etc/objects/contacts.cfg /usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/timeperiods.cfg /usr/local/nagios/etc/objects/timeperiods.cfg /usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/localhost.cfg /usr/local/nagios/etc/objects/localhost.cfg /usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/windows.cfg /usr/local/nagios/etc/objects/windows.cfg /usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/printer.cfg /usr/local/nagios/etc/objects/printer.cfg /usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/switch.cfg /usr/local/nagios/etc/objects/switch.cfg *** Config files installed *** Remember, these are *SAMPLE* config files. You'll need to read the documentation for more information on how to actually define services, hosts, etc. to fit your particular needs.
备注:这些都是一些示例配置文件,同时比如nagios.cfg在启动nagios的时候需要使用到.
10.安装apache配置文件即httpd配置文件
[root@testvm02 nagios-4.4.1]# make install-webconf /usr/bin/install -c -m 644 sample-config/httpd.conf /etc/httpd/conf.d/nagios.conf if [ 0 -eq 1 ]; then \ ln -s /etc/httpd/conf.d/nagios.conf /etc/apache2/sites-enabled/nagios.conf; \ fi *** Nagios/Apache conf file installed ***
11.配置防火墙或者关闭防火墙
配置允许8端口进入:
iptables -I INPUT -p tcp --destination-port 80 -j ACCEPT service iptables save
关闭防火墙,关闭开机启动:
service iptables stop
[root@testvm02 nagios-4.4.1]# chkconfig --level 2345 iptables off
[root@testvm02 nagios-4.4.1]# chkconfig --list | grep iptables
iptables 0:off 1:off 2:off 3:off 4:off 5:off 6:of
12.创建nagios管理账号
[root@testvm02 nagios-4.4.1]# htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin New password: #输入新密码 Re-type new password: #再次输入密码,进行确认 Adding password for user nagiosadmin
13.启动apache服务,nagios core服务
[root@testvm02 nagios-4.4.1]# service httpd start [root@testvm02 nagios-4.4.1]# service nagios start
14.通过页面进行访问测试
访问地址:http://192.168.53.25/nagios 输入nagios管理账号,密码进行登录.
登录成功之后,页面如下:
查看Hosts,Services有如下的报错:
备注:以上错误提示,表示没有某些命令,即在/usrlocal/nagios/libexex中灭有命令,需要安装nagios-plugins来安装相应的命令
15.下载,上传nagios-plugins压缩包
下载地址:
https://www.nagios.org/downloads/nagios-plugins/
软件包:nagios-plugins-2.2.1.tar.gz
[root@testvm02 softwares]# cd /opt/softwares/;ls -l nagios-plugins* -rw-r--r--. 1 root root 2728818 Jul 31 12:25 nagios-plugins-2.2.1.tar.gz
16.安装依赖的软件包,解压,编译,安装
yum install -y gcc glibc glibc-common make gettext automake autoconf wget openssl-devel net-snmp net-snmp-utils
[root@testvm02 softwares]# tar zxf nagios-plugins-2.2.1.tar.gz [root@testvm02 softwares]# cd nagios-plugins-2.2.1 [root@testvm02 nagios-plugins-2.2.1]# ./configure
[root@testvm02 nagios-plugins-2.2.1]# make
[root@testvm02 nagios-plugins-2.2.1]# make install
备注:插件安装完成
17.重新在nagios页面进行测试,在HOSTS中的localhost的命令菜单中点击."Re-schedule the next check",查看hosts状态
备注:说明命令已经成功,对于services中的检查,也会在一定时间之后,达到调度时间进行状态的修改.
Servies的状态:
18.针对HTTP的检查,在本地的/var/www/html中创建index.html文件就可以解决这个警告
[root@testvm02 libexec]# cd /var/www/html/ [root@testvm02 html]# touch index.html
配置完成之后,http服务的状态:
到此,所有的nagios-core,nagios-plugins已经安装完成!
