nagios图形界面还是比较麻烦的，下面以mysql为例来说一下。监控mysql的插件比较多，在这里了解方法，而不是死搬硬套。

一,安装pnp4nagios

请参考：nagios pnp4nagios 安装配置

二，安装perl mysql扩展

# yum install perl-Class-DBI-mysql

三，check_mysqld.php和check_mysqld.pl

1,下载

http://exchange.nagios.org/components/com_mtree/attachment.php?link_id=174&cf_id=30
http://exchange.nagios.org/components/com_mtree/attachment.php?link_id=174&cf_id=36

2,修改check_mysqld.php和check_mysqld.pl，本机是位，根本没有/usr/lib/nagios，所以要把文件中的lib改成lib

3,copy和修改文件权限

# cp check_mysqld.pl /usr/lib/nagios/plugins

# chmod 755 /usr/lib/nagios/plugins/check_mysqld.pl
# chgrp nagios /usr/lib/nagios/plugins/check_mysqld.pl

# cp check_mysqld.php /usr/share/nagios/html/pnp4nagios/templates.dist

四，nagios配置

1,修改command.cfg

# vim /etc/nagios/objects/commands.cfg

define command{
 command_name check_mysqld
 command_line $USER1$/check_mysqld.pl -H $HOSTADDRESS$ -u nagios -p $USER7$ -a uptime,threads_connected,questions,slow_queries,open_tables -w ',,,,' -c ',,,,' -A $USER21$
}

2,修改resource.cfg

# vim /etc/nagios/private/resource.cfg 

$USER7$=nagios
$USER21$='com_select,com_update,com_insert,com_insert_select,
com_commit,com_delete,com_rollback,aborted_clients,
aborted_connects,binlog_cache_disk_use,binlog_cache_use,
bytes_received,bytes_sent,connections,created_tmp_disk_tables,
created_tmp_files,created_tmp_tables,delayed_errors,
delayed_insert_threads,delayed_writes,handler_update,handler_write,
handler_delete,handler_read_first,handler_read_key,
handler_read_next,handler_read_prev,handler_read_rnd,
handler_read_rnd_next,key_blocks_not_flushed,
key_blocks_unused,key_blocks_used,key_read_requests,key_reads,
key_write_requests,key_writes,max_used_connections,
not_flushed_delayed_rows,open_files,open_streams,open_tables,
opened_tables,prepared_stmt_count,qcache_free_blocks,
qcache_free_memory,qcache_hits,qcache_inserts,
qcache_lowmem_prunes,qcache_not_cached,
qcache_queries_in_cache,qcache_total_blocks,questions,
select_full_join,select_rangle_check,slow_launch_threads,
slow_queries,table_locks_immediate,table_locks_waited,
threads_cached,threads_connected,threads_created,
threads_running'

在这里要注意，$USER21$后面的内容要在一行。

3,修改localhost.cfg

# vim /etc/nagios/objects/localhost.cfg 

define service {
 use local-service,srv-pnp //srv-pnp换成你自定义的
 host_name localhost
 service_description MYSQLD
 check_command check_mysqld!localhost!nagios!nagios
}

4,pnp4nagios中增加check_mysqld.cfg

# vim /etc/pnp4nagios/check_commands/check_mysqld.cfg

DATATYPE = COUNTER

五，重启nagios

# /etc/init.d/npcd restart
# /etc/init.d/nrpe restart
# /etc/init.d/nagios restart

六,查看结果

nagios mysql

上图可以看出，nagios配置图形监控mysql，已ok了，如果没有数据-nan的话，不要急，等一会就有数据了。
