Nagios添加服务监控

监控Web服务:在window server2003上安装IIS然后我们在nagios上做配置命令配置里面默认有httpdefine command{ command_name check_http command_line $USER1$/check_http -I $HOSTADDRESS$ $ARG1$ }配置主机和服务，主机之前已经配置好了，所以我们添加一个服务就可以[nagios@node4 ~]$ cd/usr/local/nagios/etc/objects/[nagios@node4objects]$ vim windows.cfgdefine service{ use generic-service host_name winserver service_description Web_server check_command check_http }重启nagios服务[root@node4 objects]#service nagios restartRunning configurationcheck...done.Stopping nagios:done.Starting nagios:done.然后现在我们在nagios管理界面上看到新加入的web服务了


监控mysql服务在node4上安装mysql-server# yum install mysql-server -y启动mysqld服务# service mysqldstartInitializing MySQLdatabase: Installing MySQL systemtables...OKFilling helptables...OK
To start mysqld atboot time you have to copysupport-files/mysql.serverto the right place for your system
PLEASE REMEMBER TOSET A PASSWORD FOR THE MySQL root USER !To do so, start theserver, then issue the following commands:
/usr/bin/mysqladmin-u root password 'new-password'/usr/bin/mysqladmin-u root -h node4.example.com password 'new-password'
Alternatively you canrun:/usr/bin/mysql_secure_installation
which will also giveyou the option of removing the testdatabases andanonymous user created by default. Thisisstrongly recommendedfor production servers.
See the manual formore instructions.
You can start theMySQL daemon with:cd /usr ;/usr/bin/mysqld_safe &
You can test theMySQL daemon with mysql-test-run.plcd /usr/mysql-test ;perl mysql-test-run.pl
Please report anyproblems with the /usr/bin/mysqlbug script!
[ OK ]Starting mysqld: [ OK ]# chkconfig mysqld on然后给mysql设置管理员密码# mysqladmin -u root -p password wiker #修改密码为wikerEnter password: #直接回车，默认的root密码是空[root@node4 ~]# mysql -u root -pwiker #测试下登陆Welcome to the MySQLmonitor.
