四、配置Nagios的WEB用户界面

　1.配置/etc/httpd/conf.d/nagios.conf文件 #前提已经安装上述步骤执行了 make install-webconf

# SAMPLE CONFIG SNIPPETS FOR APACHE WEB SERVER
#
# This file contains examples of entries that need
# to be incorporated into your Apache web server
# configuration file. Customize the paths, etc. as
# needed to fit your system.
#可以参考此配置文件来配置

ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"

<Directory "/usr/local/nagios/sbin">
# SSLRequireSSL
Options ExecCGI
AllowOverride None
<IfVersion >= 2.3>
<RequireAll>
Require all granted
# Require host 127.0.0.1

AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
Require valid-user
</RequireAll>
</IfVersion>
<IfVersion < 2.3>
# Order allow,deny
# Allow from all

Deny from all #默认的配置文件是注释的
Allow from 127.0.0.1 #默认的配置文件是注释的
# Allow from 192.168.0.0/24 #此处是可以修改的或者是自己添加
Allow from 10000
AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
Require valid-user
</IfVersion>
</Directory>

Alias /nagios "/usr/local/nagios/share"

<Directory "/usr/local/nagios/share">
# SSLRequireSSL
Options None
AllowOverride None
<IfVersion >= 2.3>
<RequireAll>
Require all granted
# Require host 127.0.0.1

AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
Require valid-user
</RequireAll>
</IfVersion>
<IfVersion < 2.3>
Order allow,deny
Allow from all
# Order deny,allow
# Deny from all
# Allow from 127.0.0.1

AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
Require valid-user
</IfVersion>
</Directory>

登录http://IP/nagios输入用户名密码查看是否正常。

3.配置守护进程启动：/etc/xinetd.d/nrpe

# default: on

# description: NRPE (Nagios Remote Plugin Executor)

service nrpe

{

flags = REUSE

socket_type = stream

port = 5666

wait = no

user = nagios

group = nagios

server = /usr/local/nagios/bin/nrpe

server_args = -c /usr/local/nagios/etc/nrpe.cfg --inetd

log_type = file /tmp/nrpe.log

log_on_failure += USERID

disable = no

only_from = 10.124.151.248

}

第二部分：Ndoutils的安装3.检查和配置mysql配置文件/etc/my.cnf

[mysqld_safe]
log-error=/var/log/mysqld.log

配置文件ndo2db.cfg修改如下:（主要修改三处地方：mysql端口、mysql用户名、mysql用户名密码）

# SOCKET TYPE
# This option determines what type of socket the daemon will create
# an accept connections from.
# Value:
#   unix = Unix domain socket (default)
#   tcp  = TCP socket
 
socket_type=unix
#socket_type=tcp
 
 
 
# SOCKET NAME
# This option determines the name and path of the UNIX domain

# DATABASE SERVER TYPE
# This option determines what type of DB server the daemon should connect to.

# DATABASE SOCKET
# This option specifies the path to the socket to use for local DB connections.
#
# MySQL's default location is /tmp/mysql.sock, but /var/lib/mysql/mysql.sock
# is common for RPM distributions, and /var/run/mysqld/mysqld.sock is seen on

# DATABASE NAME
# This option specifies the name of the database that should be used.
 
db_name=nagios

db_pass=ndodb  #这里要改，改成在mysql授权给一个用户的那个密码
 
 
 
## TABLE TRIMMING OPTIONS
# Several database tables containing Nagios event data can become quite large
# over time.  Most admins will want to trim these tables and keep only a
# certain amount of data in them.  The options below are used to specify the
# age (in MINUTES) that data should be allowd to remain in various tables
# before it is deleted.  Using a value of zero (0) for any value means that
# that particular table should NOT be automatically trimmed.
 
# Keep timed events for 24 hours
max_timedevents_age=1440
 
# Keep system commands for 1 week
max_systemcommands_age=10080
 
# Keep service checks for 1 week
max_servicechecks_age=10080
 
# Keep host checks for 1 week
max_hostchecks_age=10080
 
# Keep event handlers for 31 days
max_eventhandlers_age=44640
 
# Keep external commands for 31 days
max_externalcommands_age=44640
 
# Keep notifications for 31 days
max_notifications_age=44640
 
# Keep contactnotifications for 31 days
max_contactnotifications_age=44640
 
# Keep contactnotificationmethods for 31 days

# Keep logentries for 90 days

# DEBUG LEVEL
# This option determines how much (if any) debugging information will
# be written to the debug file.  OR values together to log multiple
# types of information.
# Values: -1 = Everything
#          0 = Nothing
#          1 = Process info
#      2 = SQL queries
 
debug_level=0
 
 
 
# DEBUG VERBOSITY
# This option determines how verbose the debug log out will be.
# Values: 0 = Brief output
#         1 = More detailed
#         2 = Very detailed
 
debug_verbosity=1
 
 
 
# DEBUG FILE
# This option determines where the daemon should write debugging information.
 
debug_file=/usr/local/nagios/var/ndo2db.debug
 
 
 
# MAX DEBUG FILE SIZE
# This option determines the maximum size (in bytes) of the debug file.  If
# the file grows larger than this size, it will be renamed with a .old
# extension.  If a file already exists with a .old extension it will
# automatically be deleted.  This helps ensure your disk space usage doesn't
# get out of control when debugging.
 
max_debug_file_size=1000000
 
 
# MAX OUTPUT BUFFER SIZE
# This option determines the maximum size (in bytes) of the output buffer.
# NDO2DB will start truncating characters after this value.
# If you have very large long output and you're not seeing it all in the database,
# try increasing this number.
# IMPORTANT NOTE: The 'long_output' fields in the database are set to TEXT fields, and the maximum
# size of a TEXT field is 64KB, so if you really want to make use of this field, you'll need to set
# the long_output fields to MEDIUMTEXT OR LONGTEXT.
# the long_output column exists in the following tables:
#  _eventhandlers, _hostchecks, _hoststatus, _notifications, _servicechecks, _servicestatus, _statehistory, _systemcommands
# An example sql alter statement might look like this:
# ALTER TABLE nagios_hoststatus MODIFY COLUMN long_output LONGTEXT NOT NULL DEFAULT '';
max_output_buffer_size=65536
4.设置ndo2db启动方式：




#源码中有多种方式可以启动nd02db，这里设置成init方式管理
cp /usr/local/src/ndoutils-2.1.3/startup/default-init /etc/init.d/ndo2db
#修改/etc/init.d/ndo2db
修改
NDO2DB_BIN=/usr/local/nagios/bin/ndo2db-4x　
#设置成开机自启
chkconfig ndo2db on
