nagios使用check_mysql監控mysql

nagios監控mysql服務器:
 
1、建立專用數據庫:
[root@svr3 ~]# /usr/local/webserver/mysql/bin/mysql -u root -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 51910
Server version: 5.5.3-m3-log Source distribution
 
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
 
mysql> create database nagios;
Query OK, 1 row affected (0.00 sec)
 
mysql> grant select on nagios.* to nagios@'%' identified by '123qweasd';
Query OK, 0 rows affected (0.00 sec)
 
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
 
mysql> select User,Password,Host from user;
+—————-+——————————————-+——————+
| User           | Password                                  | Host             |

| root           | *84BB5DF4823DA319BBF86C99624479A198E6EEE9 | localhost        |

+—————-+——————————————-+——————+
14 rows in set (0.00 sec)
12 rows in set (0.00 sec)
 
[root@svr3 ~]# /usr/local/nagios/libexec/check_mysql -H 10.1.1.30 -u nagios -d nagios -p 123qweasd

果斷開始設置:
#定義用戶
#定義組,及隸屬用戶
#用戶增加
 
在command.cfg裡增加插件命令:
#check mysql
define command{
command_name check_mysql
command_line $USER1$/check_mysql -H $HOSTADDRESS$ -u nagios -d nagios -p 123qweasd
}
 
#定義服務:
define service {
        host_name svr3.labexam.com
        service_description MysqlDB
        check_period 24×7
        max_check_attempts 2
        normal_check_interval 1
        retry_check_interval 1
        contact_groups sagroup,dbagroup
        notification_interval 5
        notification_period 24×7
        notification_options w,u,c,r
        check_command check_mysql
}
