 Nagios是一款Linux上成熟的监视系统运行状态和网络信息的开原IT基础设施监视系统,Nagios能监视所指定的本地或远程主机及服务,例如HTTP服务、FTP服务等,同时提供异常通知、事件处理等功能,当主机或服务出现故障时,Nagios还可以通过邮件、手机短信等形式在第一时间进行通知。Nagios可运行在Linux和Unix平台上,同时提供一个可选的基于浏览器的Web界面,方便系统管理员查看系统的运行状态、网络状态、各种系统问题及日志异常等。
环境: 192.168.0.201      mysql主机      rhel6.4
             192.186.0.202      nagios主机    rhel6.4

  yum install httpd gcc make perl-ExtUtils-Embed.x86_64 -y
  yum localinstall gd-devel-2.0.35-11.el6.x86_64.rpm  -y

安装nagios:

useradd nagios
usermod -G nagios apache
#编译所需软件包
#运行 nagios 服务的用户
#使 apache 用户对 nagios 目录具有写权限,不然 web 页面操作失败
tar jxf nagios-cn-3.2.3.tar.bz2
#nagios 软件安装
cd nagios-cn-3.2.3
./configure –enable-embedded-perl
make all      //根据提示完成安装
make install
make install-init
make install-commandmode
make install-config
make install-webconf   //在apache下通过这条命令可以快速整合

安装nagios-plugins:

yum install mysql-devel openssl-devel -y
tar zxf nagios-plugins-1.4.15.tar.gz
cd nagios-plugins-1.4.15
./configure --with-nagios-user=nagios --with-nagios-group=nagios --enable-extra-opts --enable-libtap --enable
-perl-modules
make
make install

配置nagios:

vi /usr/local/nagios/etc/nagios.cfg
Copy after login

   #cfg_file=/usr/local/nagios/etc/objects/localhost.cfg #注释掉localhost.cfg文件
   cfg_file=/usr/local/nagios/etc/objects/services.cfg  #新建 services.cfg 文件,存放服务与服务组定义
   cfg_file=/usr/local/nagios/etc/objects/hosts.cfg   #新建 hosts.cfg 文件,存放主机与主机组定义
Copy after login

配置hosts.cfg:

vi /usr/local/nagios/etc/objects/hosts.cfg
Copy after login

define host{                     //主机的管理
use linux-server                  //使用默认的主机规则
host_name vm2.example.com        //主机名
alias Nagios vm2                  //主机别名
address 127.0.0.1                 //主机ip地址
icon_image switch.gif              //图标
statusmap_image switch.gd2          
2d_coords 100,200                //2D图像坐标
3d_coords 100,200,100             //3D图像坐标
}
define hostgroup{                //主机组的管理
hostgroup_name linux-servers        //主机组名字
alias Linux Servers                //别名
members *                      //*代表上面所有主机

配置mysql
----建立nagdb专用数据库

mysql> create database nagdb default CHARSET=utf8;

Copy after login

mysql> grant select on nagdb.* to 'nagios'@'%';
Copy after login

Query OK, 0 rows affected (0.00 sec)
Copy after login
Copy after login

mysql> update mysql.user set 'Password' = PASSWORD('nagios') where 'User'='nagios';
Copy after login

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your 
MySQL server version for the right syntax to use near ''Password' = PASSWORD('nagios') where 'User'='nagios''

mysql> flush privileges;

----用以下命令来验证一下:

[root@node2 etc]# /usr/local/nagios/libexec/check_mysql -H 192.168.1.152 -u nagios -d nagdb -p nagios
Copy after login

Uptime: 3374 Threads: 1 Questions: 11 Slow queries: 0 Opens: 33 Flush tables: 1 Open tables: 26 Queries per 
second avg: 0.003
Copy after login

备注:如果出现:/usr/local/nagios/libexec/check_mysql: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No such file or directory
请查看$MYSQL_HOME/lib

[root@node2 lib]# ln -s ./libmysqlclient.so.18.0.0 /usr/lib/libmysqlclient.so.18
Copy after login

配置nrpe.cfg

[root@node2 etc]# tail /usr/local/nagios/etc/nrpe.cfg
Copy after login

command[check_mysql]=/usr/local/nagios/libexec/check_mysql -H 192.168.1.152 -u nagios -d nagdb -p nagios  
//加入此行
Copy after login

配置nagios服务端

[root@node1 etc]# cat services.cfg    //加入下面内容
Copy after login

define service{
    use               local-service
    host_name            node2
    service_description       mysql
    check_command          check_nrpe!check_mysql
    notifications_enabled      1
    }

最后重启nrpe和服务端的nagios。
