1、下载所需文件nagios-3.4.3.tar.gz,nagios-plugins-1.4.15.tar.gz,nrpe-2.14.tar.gz,sendEmail-v1.56.tar.gz
下载地址:http://pan.baidu.com/s/1ing0G
2、安装所需的依赖包
yum -y install httpd php gcc glibc glibc-common gd gd-devel openssl-devel perl make
3、配置用户
useradd nagios groupadd nagcmd usermod -a -G nagcmd nagios usermod -a -G nagcmd apache
4、安装nagios-3.4.3.tar.gz
tar zxvf nagios-3.4.3.tar.gz cd nagios ./configure --prefix=/usr/local/nagios --with-command-group=nagcmd --with-nagios-user=nagios --with-nagios-group=nagios make all make install make install-init make install-commandmode make install-config make install-webconf htpasswd -c /usr/local/nagios/etc/htpasswd.users admin #访问页面用的 chkconfig --add nagios chkconfig nagios on
修改nagios配置文件cgi.cfg,将use_authentication=1改为use_authentication=0
vi /usr/local/nagios/etc/cgi.cfg
5、安装nagios-plugins-1.4.15.tar.gz
tar zxvf nagios-plugins-1.4.15.tar.gz cd nagios-plugins-1.4.15 ./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group=nagios make && make install chown -R nagios.nagios /usr/local/nagios/
6、安装nrpe-2.14.tar.gz
tar zxvf nrpe-2.14.tar.gz cd nrpe-2.14 ./configure make all make install-plugin
7、安装 sendEmail-v1.56.tar.gz,当主机或服务宕掉或恢复时发送邮件
参考:http://www.cnblogs.com/kgdxpr/p/3326190.html
8、开始配置
修改主配置文件
vi /usr/local/nagios/etc/nagios.cfg
配置文件说明
commands.cfg 命令定义配置文件
contacts.cfg 定义联系人
timeperiods.cfg 定义监控时间段的配置文件
templates.cfg 定义主机和服务的一个模板配置文件
hosts.cfg 定义主机配置文件
services.cfg 定义服务配置文件
配置commands.cfg文件
vi /usr/local/nagios/etc/objects/commands.cfg
先修改发送邮件的命令
define command{ command_name notify-host-by-email command_line /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /usr/local/bin/sendEmail -f dsideal_lxyy@163.com -t kgdxpr@163.com -s smtp.163.com -u "** $NOTIFICATIONTYPE$ alert -$HOSTADDRESS$/$HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" -xu dsideal_lxyy -xp 123456 -m test } define command{ command_name notify-service-by-email command_line /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$\n" | /usr/local/bin/sendEmail -f dsideal_lxyy@163.com -t kgdxpr@163.com -s smtp.163.com -u "** $NOTIFICATIONTYPE$ alert -$HOSTADDRESS$/$HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" -xu dsideal_lxyy -xp 123456 -m test }
增加一个命令(用来监控memcache的端口)
define command{ command_name check_port command_line $USER1$/check_tcp -H $HOSTADDRESS$ -p 11211 $ARG2$ }
配置hosts.cfg文件
vi /usr/local/nagios/etc/objects/hosts.cfg
增加一个主机(注意:需要把注释删掉)
define host{ use linux-server #调用的是templates.cfg中的配置 host_name memcached #主机名 alias memcached_server #描述 address 10.10.3.13 #IP地址 }
配置services.cfg文件
vi /usr/local/nagios/etc/objects/services.cfg
增加一个服务(注意:需要把注释删掉)
define service { use generic-service #调用的是templates.cfg中的配置 host_name memcached #主机名,调用的是hosts.cfg中的配置 service_description test_service_description #说明 check_command check_port #用的命令,调用的是commands.cfg文件中的配置 }
9、启动Apache和nagios
为了不影响实验的结果,请关闭iptables和selinux
service iptables stop
vi /etc/sysconfig/selinux 将SELINUX=enforcing改为SELINUX=disabled (需要重启)
启动Apache前先修改一下配置,不修改的话启动时会报异常。
vi /usr/local/apache/conf/httpd.conf 找到#ServerName www.example.com:80 这行,把注释拿掉,然后改成ServerName localhost:80
chkconfig httpd on
service httpd start
service nagios start
10、访问:http://IP/nagios
用户名和密码是上面设置过的。
