  2. tar xvf ndoutils-1.4b9.tar.gz
  3. cd ndoutils-1.4b9
  4. ./configure --prefix=/usr/local/nagios/ --with-mysql --with-ndo2db-user=nagios --with-ndo2db-group=nagios --with-ssl --with-ssl-lib --enable-mysql --enable-ssl --with-mysql-inc=/usr/include/mysql --with-mysql-lib=/usr/lib64/mysql --disable-pgsql
  5. make（不用make install）


6.3复制文件


  1. cp src/{ndomod-3x.o,ndo2db-3x,log2ndo,file2sock}/usr/local/nagios/bin/
  2. cp config/ndo2db.cfg-sample /usr/local/nagios/etc/ndo2db.cfg
  3. cp config/ndomod.cfg-sample /usr/local/nagios/etc/ndomod.cfg
  4. chmod 644 /usr/local/nagios/etc/ndo*


6.4修改配置文件信息，连接数据库

注意：修改之前先做好备份


  1. vim /usr/local/nagios/etc/ndo2db.cfg //红色数字为行号
  2. 21 ndo2db_user=nagios
  3. 22 ndo2db_group=nagios
  4. 34 socket_type=tcp //将此行#号去掉，socket_type=unix前面加上#号
  5. 102 db_name=cacti //创建的数据库的名字

3.4.7 Cacti添加被监控主机

7.1监控端的设置

Cacti中添加监控主机设置方法：

① 添加设备


报错：SNMP错误

解决办法：是因为被监控端没有启动snmp

service snmpd restart

然后到监控端cacti服务器上

snmpwalk -c public -v 2c 192.168.1.222    --> (这个ip为被监控主机的ip)

如果能够接收到被监控机器的数据信息，则表示被监控主机的snmp配置已经完成，没有错误。如果没有接收到被监控主机的数据信息，那么进行第三步操作。

 

 

第三，用root登录被监控主机，修改snmp的配置文件：


  1. vi /etc/snmp/snmpd.conf
  2. 最后配置如下：
  3. syslocation Server Room
  4. syscontact Sysadmin (root@localhost)
  5. rocommunity public 127.0.0.1
  6. agentaddress 161
  7. rocommunity public
  8. rwcommunity private
  9. trapsink 192.168.124.14 public 162 -->这里的ip=192.168.124.14为被监控主机ip


然后，再执行第二步操作即可。

Nagios NRPE监控远程主机

8.1监控端的设置

监控机安装NRPE


  1. wget http://nchc.dl.sourceforge.net/sourceforge/nagios/nrpe-2.12.tar.gz
  2. tar zxvf nrpe-2.12.tar.gz 
  3. cd nrpe-2.12
  4. ./configure --prefix=/usr/local/nagios
  5. make all
  6. make install-plugin
  7. #监控机只需安装到这步


8.2被监控端的设置

8.2.1被监控端添加用户


  1. groupadd nagios
  2. useradd -g nagios -d /usr/local/nagios -s /sbin/nologin nagios


8.2.2被监控端安装nagios- plugins插件

  1. wget http://nchc.dl.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.13.tar.gz
  2. tar zxf nagios-plugins-1.4.13.tar.gz
  3. cd nagios-plugins-1.4.13
  4. ./configure --with-nagios-user=nagios --with-nagios-group=nagios --prefix=/usr/local/nagios --with-ping-command="/bin/ping" --with-mysql=/opt/mysql
  5. make
  6. make install

#查看插件文件是否已安装在这个目录

  1. ls /usr/local/nagios/libexec

8.2.3被监控端安装NRPE

  1. wget http://nchc.dl.sourceforge.net/sourceforge/nagios/nrpe-2.12.tar.gz
  2. tar zxvf nrpe-2.12.tar.gz
  3. cd nrpe-2.12
  4. ./configure --prefix=/usr/local/nagios
  5. make all
  6. make install-plugin
  7. make install-daemon
  8. make install-daemon-config
  9. chown -R nagios:nagios /usr/local/nagios

8.2.4配置被监控端的NRPE:

  1. vi /usr/local/nagios/etc/nrpe.cfg
  2. allowed_hosts=127.0.0.1,192.168.1.22 #Nagios监控机的地址或域名

修改/etc/hosts.allow增加监控机ip

  1. echo 'nrpe:192.168.1.22' >> /etc/hosts.allow 

8.2.5启动NRPE守护进程：

  1. /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d

8.2.6将nrpe加入/etc/rc.local，以便开机自动启动。

  1. echo "/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d" >> /etc/rc.local

8.2.7检查NRPE是否正常：

在被监控机上

  1. /usr/local/nagios/libexec/check_nrpe -H 127.0.0.1

查看相应的端口：

  1. netstat -an |grep 5666

防火墙开启5666允许局域网IP或固定IP连接

 

在监控主机上

  1. /usr/local/nagios/libexec/check_nrpe -H 192.168.1.222 $目标主机地址（被监控端地址）

都应该可以输出NRPE的版本：NRPE v2.12

 

8.2.8检查可监控的服务

在被监控端的nrpe.cfg文件中，可以看到这样的配置：

command[check_load]=/usr/local/nagios/libexec/check_load -w 15,10,5 -c 30,25,20

这是用来检查CPU负载的。

 

8.2.9配置被监控端的nrpe.cfg

  1. vim /usr/local/nagios/etc/nrpe.cfg
  2. 添加以下内容：
  3. command[check_users]=/usr/local/nagios/libexec/check_users -w 5 -c 10
  4. command[check_load]=/usr/local/nagios/libexec/check_cpu.sh -w 80% -c 90%
  5. command[check_sda1]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/sda1
  6. command[check_sda2]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/sda2
  7. command[check_zombie_procs]=/usr/local/nagios/libexec/check_procs -w 5 -c 10 -s Z
  8. command[check_total_procs]=/usr/local/nagios/libexec/check_procs -w 150 -c 200
  9. command[check_swap]=/usr/local/nagios/libexec/check_swap -w 20% -c 10%
  10. command[check_iostat]=/usr/local/nagios/libexec/check_iostat.sh -d sda -w 6 -c 10
  11. command[check_mysql]=/usr/local/nagios/libexec/check_mysql -H 192.168.0.22 -u nagios -p 123456 -d nagios
  12. command[check_nginx]=/usr/local/nagios/libexec/check_nginx.sh -u 192.168.0.22 -p /status -w 4000 -c 5000
  13. command[check_mem]=/usr/local/nagios/libexec/check_memory.pl -f -w 20 -c 10

如果需要自定参数则使用下面命令

command[check_load]=/usr/local/nagios/libexec/check_load -w $ARG1$ -c $ARG2$

并开启dont_blame_nrpe =1

开启参数将会带来一定的安全风险

 

8.2.10被监控机重启nrpe

  1. ps aux|grep nrpe
  2. kill $pid
  3. /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg –d

8.3监控机NRPE的设置

8.3.1在监控机commands.cfg添加nrpe的定义

  1. vim /usr/local/nagios/etc/objects/commands.cfg
  2. # 'check_nrpe ' command definition
  3. define command{
  4. command_name check_nrpe
  5. command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
  6. }

8.3.2在监控机的/usr/local/nagios/etc/objects/下添加被监控机的配置文件app1.cfg，并配置

在/usr/local/nagios/etc/objects/目录下新建文件：app1.cfg

把app1.cfg添加到nagios主机：

  1. echo "cfg_file=/usr/local/nagios/etc/objects/app1.cfg" >> /usr/local/nagios/etc/nagios.cfg

如果要再添加B机器如法炮制就可以了

  1. Vim app1.cfg
  2. define host{
  3. use linux-server
  4. host_name nagios-client
  5. alias nagios-client
  6. address 192.168.1.222 //被监控端的IP地址
  7. icon_image server.gif
  8. statusmap_image server.gd2
  9. 2d_coords 500,200
  10. 3d_coords 500,200,100
  11. }
  12. define service{
  13. use local-service ; Name of service template to use
  14. host_name *
  15. service_description PING
  16. check_command check_ping!100.0,20%!500.0,60%
  17. }
  18. define service{
  19. use local-service ; Name of service template to use
  20. host_name nagios-client
  21. service_description boot分区
  22. check_command check_nrpe!check_sda1
  23. }
  24. define service{
  25. use local-service ; Name of service template to use
