Nagios安装中遇到的问题点，记录一下

网络上有好多安装方法，我仅记录自己安装后的问题

1，网页打不开

service iptables stop 关闭防火墙

或者 vi /etc/sysconfig/iptables

添加此条目 -A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT 开通80口

vi /etc/httpd/conf/httpd.conf

<IfModule dir_module>

　　DirectoryIndex index.html index.php

　　AddType application/x-httpd-php .php

</IfModule>                                               这两个很重要 ，我两次安装，都打错字！！ 

后追加

#Setting for nagios

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

<Directory "/usr/local/nagios/sbin">

    Options ExecCGI

    AllowOverride None

    Order allow,deny

    Allow from all

    AuthName "Nagios Access"

    AuthType Basic

    AuthUserFile /usr/local/nagios/etc/htpasswd

    Require valid-user

</Directory>

Alias /nagios /usr/local/nagios/share

<Directory "/usr/local/nagios/share">

    Options None

    AllowOverride None

    Order allow,deny

    Allow from all

    AuthName "Nagios Access"

    AuthType Basic

    AuthUserFile /usr/local/nagios/etc/htpasswd

    Require valid-user

</Directory>

2，权限问题打不开

vi /etc/selinux/config

SELINUX=disabled

3,检查所有配置文件的正确性

/usr/local/nagios/bin/nagios-v /usr/local/nagios/etc/nagios.cfg

Total Warnings: 0

Total Errors:   0

都是0，很明显，没问题。如果有问题，请仔细查看报错项目

4，出问题，看日志

cat /usr/local/apache2/logs/error_log 

不急不躁，方能成功

5，如果commands.cfg报错 后追加

 # ‘notify-host-by-email’ command definition

 define command{

 command_name host-notify-by-email

 command_line /usr/bin/printf “%b” “***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost:       $HOSTNAME$\nState:$HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time:      $LONGDATETIME$\n” | /bin/mail -s “** $NOTIFICATIONTYPE$
Host Alert: $HOSTNAME$ is $HOSTSTATE$ **”  $CONTACTEMAIL$

 }

  # ’service_notification_commands’ command definition

 define command{

 command_name service-notify-by-email

 command_line /usr/bin/printf “%b” “***** Nagios *****\n\nNotification Type: $NOT
4000
IFICATIONTYPE$\n\nService:   $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time:  $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$”
| /bin/mail -s “** $NOTIFICATIONTYPE$ Service Alert:  $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **” $CONTACTEMAIL$
