continue
fi
done
5，安装与配置nagios
/usr/sbin/useradd -m nagios
进入下载目录
tar zxvf nagios-3.2.0.tar.gz
cd nagios-3.2.0
./configure --prefix=/usr/local/nagios
make all
# 使用make install来安装主程序,CGI和HTML文件
make install
# 使用make install-init在/etc/rc.d/init.d安装启动脚本
make install-init
# 使用make install-cofig来安装示例配置文件,安装的路径是/usr/local/nagios/etc.
make install-config
# 使用make install-commandmode来配置目录权限
make install-commandmode
nagios目录功能的简要说明：
bin Nagios执行程序所在目录，nagios文件即为主程序
etc Nagios配置文件位置
sbin Nagios Cgi文件所在目录，也就是执行外部命令所需文件所在的目录
Share Nagios网页文件所在的目录
var Nagios日志文件、spid 等文件所在的目录
var/archives 日志归档目录
var/rw 用来存放外部命令文件
配置apache
ScriptAlias /nagios/cgi-bin /usr/local/nagios/sbin
<Directory "/usr/local/nagios/sbin"> ＃Cgi文件所在目录
AuthType Basic
Options ExecCGI
AllowOverride None
Order allow,deny
Allow from all
AuthName "Nagios Access"
AuthUserFile /usr/local/nagios/etc/htpasswd ＃验证文件路径
Require valid-user
</Directory>
Alias /nagios /usr/local/nagios/share
<Directory "/usr/local/nagios/share"> ＃nagios页面文件目录
AuthType Basic
Options None
AllowOverride None
Order allow,deny
Allow from all
AuthName "nagios Access"
AuthUserFile /usr/local/nagios/etc/htpasswd ＃验证文件路径
Require valid-user
</Directory>
＃ 创建apache目录验证文件
/usr/local/apache/bin/htpasswd -c /usr/local/nagios/etc/htpasswd test
New password: (输入密码)
Re-type new password: (再输入一次密码)
＃ 重启apache：/usr/local/apache/bin/apachectl -k restart
以后在添加文件不需要加-c的参数，-c是建立passwdfile文件。如果passwdfile已经存在，则它被重写并截断，所以要添加新用户就直接
/usr/local/apache/bin/htpasswd /usr/local/nagios/etc/htpasswd test2
这里我们提前建立好一个以后发送短信的用户
/usr/local/apache/bin/htpasswd /usr/local/nagios/etc/htpasswd sendmsg
New password: (输入密码)
Re-type new password: (再输入一次密码)
启动Nagios
＃ 配置机器启动时自动启动Nagios
chkconfig --add nagios
chkconfig nagios on
安装Nagios插件
tar xzf nagios-plugins-1.4.14.tar.gz
cd nagios-plugins-1.4.14
./configure
make
make install
安装nrpe插件，用来监控Linux机器
tar xzvf nrpe-2.12.tar.gz
cd nrpe-2.12
./configure
make all
＃ 在Nagios服务器端只要安装nrpe监控插件就行
make install-plugin
接下来修改nagios的主配置文件nagios.cfg
vi /usr/local/nagios/etc/nagios.cfg
＃添加或修改下面的配置
cfg_file=/usr/local/nagios/etc/objects/commands.cfg ＃ 命令的配置文件路径
cfg_file=/usr/local/nagios/etc/objects/contacts.cfg ＃ 联系人配置文件路径
cfg_file=/usr/local/nagios/etc/objects/contactgroups.cfg ＃ 联系组配置文件路径
cfg_file=/usr/local/nagios/etc/objects/timeperiods.cfg ＃ 监视时段配置文件路径
cfg_file=/usr/local/nagios/etc/objects/templates.cfg ＃ 模板的配置文件路径
cfg_file=/usr/local/nagios/etc/objects/hostgroups.cfg ＃ 主机组配置文件路径
cfg_file=/usr/local/nagios/etc/objects/hosts.cfg ＃ 主机配置文件路径
cfg_file=/usr/local/nagios/etc/objects/services.cfg ＃ 服务配置文件路径
＃把关于windows的配置选项前面的＃号去掉
cfg_file=/usr/local/nagios/etc/objects/windows.cfg
＃把server目录配置前面的＃去掉，记得手动创建目录
cfg_dir=/usr/local/nagios/etc/servers
＃如果需要查看日志就把下面的配置加上，记得自己手动创建目录
log_file=/usr/local/nagios/var/nagios.log
debug_file=/usr/local/nagios/var/nagios.debug
debug_level=32
＃修改CGI脚本控制文件cgi.cfg
vi /usr/local/nagios/etc/cgi.cfg
＃是否开启验证，1是开启0是关闭
use_authentication=1
＃修改默认用户
default_user_name=test
＃多个用户之间用逗号隔开
authorized_for_system_information=nagiosadmin,test
authorized_for_configuration_information=nagiosadmin,test
authorized_for_system_commands=test
authorized_for_all_services=nagiosadmin,test
authorized_for_all_hosts=nagiosadmin,test
authorized_for_all_service_commands=nagiosadmin,test
authorized_for_all_host_commands=nagiosadmin,test
定义监控时间段,配置文件timeperiods.cfg
vi /usr/local/nagios/etc/objects/timeperiods.cfg
＃以下的配置只能用tab键来相隔，不能用空格
＃默认是有以下配置的
＃定义了一个监控时间段,它的名称是24x7,监控的时间是每天全天24小时
define timeperiod{
timeperiod_name 24x7
alias 24 Hours A Day, 7 Days A Week
sunday 00:00-24:00
monday 00:00-24:00
tuesday 00:00-24:00
wednesday 00:00-24:00
thursday 00:00-24:00
friday 00:00-24:00
saturday 00:00-24:00
}
定义联系人,配置文件contacts.cfg
vi /usr/local/nagios/etc/objects/contacts.cfg
＃以下的配置只能用tab键来相隔，不能用空格
＃添加下面的配置
define contact{
contact_name test
alias Sys Admin ; Full name of user
contactgroups sagroup
service_notification_period 24x7 ; 服务出了状况通知的时间段,这个时间段就是上面在timeperiods.cfg中定义的.
host_notification_period 24x7 ; 主机出了状况通知的时间段, 这个时间段就是上面在timeperiods.cfg中定义的
service_notification_options w,u,c,r ; 当服务出现w―报警(warning),u―未知(unkown),c―严重(critical),或者r―从异常情况恢复正常,在这四种情况下通知联系 人.
host_notification_options d,u,r ; 当主机出现d―当机(down),u―返回不可达(unreachable),r―从异常情况恢复正常,在这3种情况下通知联系人
service_notification_commands notify-service-by-email ; 服务出问题通知采用的命令notify-service-by-email,这个命令是在commands.cfg中定义的,作用是给联系人发邮件.
host_notification_commands notify-host-by-email ; 主机出问题时采用的也是发邮件的方式通知联系人
email [email protected] ; 联系的人email地址
}
define contact{
contact_name sendmsg
alias Sys Admin ; Full name of user
contactgroups sendmsggroup
service_notification_period 24x7
host_notification_period 24x7
service_notification_options w,u,c,r
host_notification_options d,u,r
service_notification_commands notify-service-by-sendmsg ; 服务出问题通知采用的命令notify-service-by-sendmsg,这个命令是在commands.cfg中定义的,作用是给联系人发短信.
host_notification_commands notify-host-by-sendmsg ; 主机出问题时采用的也是发邮件的方式通知联系人
email [email protected]
}
将多个联系人组成一个联系人组,创建文件contactgroups.cfg
vi /usr/local/nagios/etc/objects/contactgroups.cfg
＃以下的配置只能用tab键来相隔，不能用空格
＃要添加多个用户到sagroup组只需要在members后面继续增加用户名即可，需要用逗号（，）相隔
define contactgroup{
contactgroup_name sagroup
alias Novell Administrators
members test
}
define contactgroup{
contactgroup_name sendmsggroup
alias Sendmsg Administrators
members sendmsg
}
定义被监控主机,创建文件hosts.cfg
vi /usr/local/nagios/etc/objects/hosts.cfg
＃以下的配置只能用tab键来相隔，不能用空格
define host{
host_name nagios-server ＃定义主机名字
alias wd-linux-216 ＃定义别名
address 192.168.0.216 ＃真是ip地址
check_command check-host-alive ＃监控的命令check-host-alive,这个命令来自commands.cfg,用来监控主机是否存活
max_check_attempts 5 ＃检查失败后重试的次数
check_period 24x7 ＃检查的时间段24x7,同样来自于我们之前在timeperiods.cfg中定义的
contact_groups sagroup ＃联系人组,上面在contactgroups.cfg中定义的sagroup
notification_interval 10 ＃提醒的间隔,每隔10秒提醒一次
notification_period 24x7 ＃提醒的周期, 24x7,同样来自于我们之前在timeperiods.cfg中定义的
notification_options d,u,r ＃指定什么情况下提醒,具体含义见之前contacts.cfg部分的介绍
}
与联系人可以组成联系人组一样,多个主机也可以组成主机组.创建文件hostgrops.cfg
vi /usr/local/nagios/etc/objects/hostgroups.cfg
＃以下的配置只能用tab键来相隔，不能用空格
＃同样，多台主机名需要用逗号（，）相隔
＃事先加好其他的主机名到组里，稍候再讲其他主机名的配置
define hostgroup{
hostgroup_name linux-servers
alias Linux Servers
members nagios-server,192.168.0.19,192.168.0.113
}
define hostgroup{
hostgroup_name windows-servers
alias Windows Servers
members 192.168.0.80,192.168.0.229

＃在这里说明下，host_name是主机名称需要在host中有定义，本例在192.168.0.19_l.cfg这个配置文件中先配置了host，然 后在配置了server，这样做的好处是便于管理，如果以后监控的机器非常多都写在hosts.cfg和services.cfg文件中，那样查看起来比 较麻烦，所以这样分机器些配置文件是便于以后的管理，现在把其他的被监控的机器也分别配置好就可以，这里可以以192.168.0.19_l.cfg为 例，来copy成其他需要被监控的文件，在修改下主机名就可以了，这样以后再加新的机器就简单多了。

监控sqlserver需要安装插件freeTDS
wget http://dag.wieers.com/rpm/packages/freetds/freetds-0.62.1-0.el5.rf.i386.rpm
rpm -ivh --nodeps freetds-0.62.1-0.el5.rf.i386.rpm
＃查看是否被安装
rpm -qa |grep freetds
现在来配置nagios的commands.cfg文件
＃上面的好多命令如check_http_uri是不存在的需要自己添加
vi /usr/local/nagios/etc/objects/commands.cfg
＃添加下面的内容
＃调用飞信机器人发送短信报警
define command {
command_name notify-host-by-sendmsg
command_line /usr/local/fetion/sendsms.sh "Host $HOSTSTATE$ alert for $HOSTNAME$($HOSTADDRESS$) on $TIME$."
}
＃调用飞信机器人发送短信报警
define command {
command_name notify-service-by-sendmsg
command_line /usr/local/fetion/sendsms.sh ""$TIME$":$SERVICEDESC$($HOSTADDRESS$) is $SERVICESTATE$."
}
# 'check_nrpe ' command definition
define command{
command_name check_nrpe
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}
# 'check_mysql ' command definition
define command{
command_name check_mysql
command_line $USER1$/check_mysql -H $HOSTADDRESS$ -u $ARG1$ -p $ARG2$ -P $ARG3$ $ARG4$
}
# 'check_mssql ' command definition
define command{
command_name check_mssql
command_line $USER1$/check_mssql $HOSTADDRESS$ $ARG1$ $ARG2$ $ARG3$
}
# 'check_http_uri' command definition
define command{
command_name check_http_uri
command_line $USER1$/check_http -I $HOSTADDRESS$ -p $ARG1$ -u $ARG2$ $ARG3$
}
保存退出
这里大概讲一下，commands.cfg配置文件的原理是调用nagios-plugins插件安装产生的工具来检查各个机器的相应状况，nagios-plugins插件安装产生的工具所在目录为 /usr/local/nagios/libexec/
＃注意check_mssql默认是没有的需要从网上下载或者自己编译
＃check_mysql如果没有就需要安装mysql_client，然后在重新安装nagios-plugins，如果实在没有就从别的地方copy过来也可以，我就是从别的地方copy过来的！
好了，到此nagios的server端已经安装和配置完，下面我们去被监控机器上去安装插件
6，被监控机器上 安装插件
linux被监控机器的安装
useradd nagios
tar xzvf nagios-plugins-1.4.13.tar.gz
cd nagios-plugins-1.4.13
＃ Nagios-plugins默认安装到/usr/local/nagios
./configure
make
make install
chown nagios.nagios /usr/local/nagios/
chown -R nagios.nagios /usr/local/nagios/libexec/
tar xzvf nrpe-2.12.tar.gz
cd nrpe-2.12
./configure
make all
＃ 安装nrpe插件，本监控端可以不装
make install-plugin
# 安装nrpe守护进程
make install-daemon
＃ 安张nrpe配置文件
make install-daemon-config
＃ 修改nrpe配置文件，允许Nagios监控服务器（192.168.0.19）监控
vi nrpe.cfg
＃ 多台机器用逗号隔开
allowed_hosts=127.0.0.1,192.168.0.216
＃ 以独立守护进程启动nrpe，也可以使用xinetd启动nrpe，具体清查看nrpe官方文档。
/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
＃ 开机自动启动nrpe
echo "/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d" >> /etc/rc.d/rc.local
＃ 检查nrpe是否安装正常
[root@wiki etc]# /usr/local/nagios/libexec/check_nrpe -H localhost
NRPE v2.12
＃ 返回nrpe版本说明安装没问题。
＃ 查看启动端口
[root@wiki ~]# netstat -tunlp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 0.0.0.0:5666 0.0.0.0:* LISTEN 27387/nrpe
如果有防火墙应该开放5666端口：
iptables -I eth0 -p tcp -m tcp �Cdport 5666 -j ACCEPT
windows被监控机的安装
下载NSClient++-Win32-0.3.6.msi
进行安装
到安装目录打开NSC.ini文件进行修改：
C:\Program Files\NSClient++\NSC.ini
编辑NSC.ini文件
在[modules]模块，将除CheckWMI.dll和RemoteConfiguration.dll外的所有dll文件名前的注释（;)去掉。
在[Settings]模块可以设置一个连接密码password=PWD，为了简单，在此不设密码。设置 allowed_hosts=127.0.0.1/32,192.168.0.216，可以连接的监控服务器的地址，如果写成192.168.0.0 /24则表示该子网内的所有机器都可以访问；如果这个地方是空白则表示所有的主机都可以连接上来（注意在[NSClient]有 allowed_hosts的同样设置，不要设置错了），最后不要忘记去掉前面的注释符（;）。
运行nsclient＋＋
cd C:\Program Files\NSClient++
NSClient++ /start （也可以在服务管理器中去启动、重启NSClientpp）
如果有防火墙，请开放相应端口。
创建监控配置文件，使用check_nt命令监控windows系统信息（此命令默认已定义）。
到此位置被监控机的安装也已经都完成了
7.检查nagios的所有配置文件并启动nagios
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

看到上面的提示就表示都ok了，如果有问题就按照提示一一调整，切记nagios的大部分配置文件里不支持空格尽量用TAB键来相隔，下面我们来重启nagios
service nagios restart
打开浏览器输入网址就可以访问nagios了
http://192.168.0.216/nagios/
输入用户名 test
密码 密码
现在我们就看到nagios的监控页面了，并且如果出现问题是可以发邮件和短信报警的了！！
到此配置基本结束，当然nagios是相当强大的这里只是发挥了一小部分的功能。如果大家对nagios感兴趣请下载官方文档

echo "quit" >> $DIR/msg.txt
$fetionDir/fetion --mobile=$user --pwd=$pwd --to=$phone --msg-utf8=$1
else
continue
fi
done
5，安装与配置nagios
/usr/sbin/useradd -m nagios
进入下载目录
tar zxvf nagios-3.2.0.tar.gz
cd nagios-3.2.0
./configure --prefix=/usr/local/nagios
make all
# 使用make install来安装主程序,CGI和HTML文件
make install
# 使用make install-init在/etc/rc.d/init.d安装启动脚本
make install-init
# 使用make install-cofig来安装示例配置文件,安装的路径是/usr/local/nagios/etc.
make install-config
# 使用make install-commandmode来配置目录权限
make install-commandmode
nagios目录功能的简要说明：
bin Nagios执行程序所在目录，nagios文件即为主程序
etc Nagios配置文件位置
sbin Nagios Cgi文件所在目录，也就是执行外部命令所需文件所在的目录
Share Nagios网页文件所在的目录
var Nagios日志文件、spid 等文件所在的目录
var/archives 日志归档目录
var/rw 用来存放外部命令文件
配置apache
ScriptAlias /nagios/cgi-bin /usr/local/nagios/sbin
<Directory "/usr/local/nagios/sbin"> ＃Cgi文件所在目录
AuthType Basic
Options ExecCGI
AllowOverride None
Order allow,deny
Allow from all
AuthName "Nagios Access"
AuthUserFile /usr/local/nagios/etc/htpasswd ＃验证文件路径
Require valid-user
</Directory>
Alias /nagios /usr/local/nagios/share
<Directory "/usr/local/nagios/share"> ＃nagios页面文件目录
AuthType Basic
Options None
AllowOverride None
Order allow,deny
Allow from all
AuthName "nagios Access"
AuthUserFile /usr/local/nagios/etc/htpasswd ＃验证文件路径
Require valid-user
</Directory>
＃ 创建apache目录验证文件
/usr/local/apache/bin/htpasswd -c /usr/local/nagios/etc/htpasswd test
New password: (输入密码)
Re-type new password: (再输入一次密码)
＃ 重启apache：/usr/local/apache/bin/apachectl -k restart
以后在添加文件不需要加-c的参数，-c是建立passwdfile文件。如果passwdfile已经存在，则它被重写并截断，所以要添加新用户就直接
/usr/local/apache/bin/htpasswd /usr/local/nagios/etc/htpasswd test2
这里我们提前建立好一个以后发送短信的用户
/usr/local/apache/bin/htpasswd /usr/local/nagios/etc/htpasswd sendmsg
New password: (输入密码)
Re-type new password: (再输入一次密码)
启动Nagios
＃ 配置机器启动时自动启动Nagios
chkconfig --add nagios
chkconfig nagios on
安装Nagios插件
tar xzf nagios-plugins-1.4.14.tar.gz
cd nagios-plugins-1.4.14
./configure
make
make install
安装nrpe插件，用来监控Linux机器
tar xzvf nrpe-2.12.tar.gz
cd nrpe-2.12
./configure
make all
＃ 在Nagios服务器端只要安装nrpe监控插件就行
make install-plugin
接下来修改nagios的主配置文件nagios.cfg
vi /usr/local/nagios/etc/nagios.cfg
＃添加或修改下面的配置
cfg_file=/usr/local/nagios/etc/objects/commands.cfg ＃ 命令的配置文件路径
cfg_file=/usr/local/nagios/etc/objects/contacts.cfg ＃ 联系人配置文件路径
cfg_file=/usr/local/nagios/etc/objects/contactgroups.cfg ＃ 联系组配置文件路径

＃把关于windows的配置选项前面的＃号去掉
cfg_file=/usr/local/nagios/etc/objects/windows.cfg
＃把server目录配置前面的＃去掉，记得手动创建目录
cfg_dir=/usr/local/nagios/etc/servers
＃如果需要查看日志就把下面的配置加上，记得自己手动创建目录
log_file=/usr/local/nagios/var/nagios.log
debug_file=/usr/local/nagios/var/nagios.debug
debug_level=32
＃修改CGI脚本控制文件cgi.cfg
vi /usr/local/nagios/etc/cgi.cfg
＃是否开启验证，1是开启0是关闭
use_authentication=1
＃修改默认用户
default_user_name=test
＃多个用户之间用逗号隔开
authorized_for_system_information=nagiosadmin,test
authorized_for_configuration_information=nagiosadmin,test
authorized_for_system_commands=test
authorized_for_all_services=nagiosadmin,test
authorized_for_all_hosts=nagiosadmin,test
authorized_for_all_service_commands=nagiosadmin,test
authorized_for_all_host_commands=nagiosadmin,test
定义监控时间段,配置文件timeperiods.cfg
vi /usr/local/nagios/etc/objects/timeperiods.cfg
＃以下的配置只能用tab键来相隔，不能用空格
＃默认是有以下配置的
＃定义了一个监控时间段,它的名称是24x7,监控的时间是每天全天24小时
define timeperiod{
timeperiod_name 24x7
alias 24 Hours A Day, 7 Days A Week
sunday 00:00-24:00
monday 00:00-24:00
tuesday 00:00-24:00
wednesday 00:00-24:00
thursday 00:00-24:00
friday 00:00-24:00
saturday 00:00-24:00
}
定义联系人,配置文件contacts.cfg
vi /usr/local/nagios/etc/objects/contacts.cfg
＃以下的配置只能用tab键来相隔，不能用空格
＃添加下面的配置
define contact{
contact_name test
alias Sys Admin ; Full name of user
contactgroups sagroup
service_notification_period 24x7 ; 服务出了状况通知的时间段,这个时间段就是上面在timeperiods.cfg中定义的.
host_notification_period 24x7 ; 主机出了状况通知的时间段, 这个时间段就是上面在timeperiods.cfg中定义的
service_notification_options w,u,c,r ; 当服务出现w―报警(warning),u―未知(unkown),c―严重(critical),或者r―从异常情况恢复正常,在这四种情况下通知联系 人.
host_notification_options d,u,r ; 当主机出现d―当机(down),u―返回不可达(unreachable),r―从异常情况恢复正常,在这3种情况下通知联系人
service_notification_commands notify-service-by-email ; 服务出问题通知采用的命令notify-service-by-email,这个命令是在commands.cfg中定义的,作用是给联系人发邮件.
host_notification_commands notify-host-by-email ; 主机出问题时采用的也是发邮件的方式通知联系人
email [email protected] ; 联系的人email地址
}
define contact{
contact_name sendmsg
alias Sys Admin ; Full name of user
contactgroups sendmsggroup
service_notification_period 24x7
host_notification_period 24x7
service_notification_options w,u,c,r
host_notification_options d,u,r
service_notification_commands notify-service-by-sendmsg ; 服务出问题通知采用的命令notify-service-by-sendmsg,这个命令是在commands.cfg中定义的,作用是给联系人发短信.
host_notification_commands notify-host-by-sendmsg ; 主机出问题时采用的也是发邮件的方式通知联系人
email [email protected]
}
将多个联系人组成一个联系人组,创建文件contactgroups.cfg
vi /usr/local/nagios/etc/objects/contactgroups.cfg
＃以下的配置只能用tab键来相隔，不能用空格
＃要添加多个用户到sagroup组只需要在members后面继续增加用户名即可，需要用逗号（，）相隔
define contactgroup{
contactgroup_name sagroup
alias Novell Administrators
members test
}
define contactgroup{
contactgroup_name sendmsggroup
alias Sendmsg Administrators
members sendmsg
}
定义被监控主机,创建文件hosts.cfg
vi /usr/local/nagios/etc/objects/hosts.cfg
＃以下的配置只能用tab键来相隔，不能用空格
define host{
host_name nagios-server ＃定义主机名字
alias wd-linux-216 ＃定义别名

rpm -ivh --nodeps freetds-0.62.1-0.el5.rf.i386.rpm
＃查看是否被安装
rpm -qa |grep freetds
现在来配置nagios的commands.cfg文件
＃上面的好多命令如check_http_uri是不存在的需要自己添加
vi /usr/local/nagios/etc/objects/commands.cfg
＃添加下面的内容
＃调用飞信机器人发送短信报警
define command {
command_name notify-host-by-sendmsg
command_line /usr/local/fetion/sendsms.sh "Host $HOSTSTATE$ alert for $HOSTNAME$($HOSTADDRESS$) on $TIME$."
}
＃调用飞信机器人发送短信报警

command_name notify-service-by-sendmsg
command_line /usr/local/fetion/sendsms.sh ""$TIME$":$SERVICEDESC$($HOSTADDRESS$) is $SERVICESTATE$."
}
# 'check_nrpe ' command definition

define command{
command_name check_http_uri
command_line $USER1$/check_http -I $HOSTADDRESS$ -p $ARG1$ -u $ARG2$ $ARG3$
}
保存退出
这里大概讲一下，commands.cfg配置文件的原理是调用nagios-plugins插件安装产生的工具来检查各个机器的相应状况，nagios-plugins插件安装产生的工具所在目录为 /usr/local/nagios/libexec/
＃注意check_mssql默认是没有的需要从网上下载或者自己编译
＃check_mysql如果没有就需要安装mysql_client，然后在重新安装nagios-plugins，如果实在没有就从别的地方copy过来也可以，我就是从别的地方copy过来的！
好了，到此nagios的server端已经安装和配置完，下面我们去被监控机器上去安装插件
6，被监控机器上 安装插件
linux被监控机器的安装
useradd nagios
tar xzvf nagios-plugins-1.4.13.tar.gz
cd nagios-plugins-1.4.13
＃ Nagios-plugins默认安装到/usr/local/nagios
./configure
make
make install
chown nagios.nagios /usr/local/nagios/
chown -R nagios.nagios /usr/local/nagios/libexec/
tar xzvf nrpe-2.12.tar.gz
cd nrpe-2.12
./configure
make all
＃ 安装nrpe插件，本监控端可以不装
make install-plugin
# 安装nrpe守护进程
make install-daemon
＃ 安张nrpe配置文件
make install-daemon-config
＃ 修改nrpe配置文件，允许Nagios监控服务器（192.168.0.19）监控
vi nrpe.cfg
＃ 多台机器用逗号隔开
allowed_hosts=127.0.0.1,192.168.0.216
＃ 以独立守护进程启动nrpe，也可以使用xinetd启动nrpe，具体清查看nrpe官方文档。
/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
＃ 开机自动启动nrpe
echo "/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d" >> /etc/rc.d/rc.local
＃ 检查nrpe是否安装正常
[root@wiki etc]# /usr/local/nagios/libexec/check_nrpe -H localhost
NRPE v2.12
＃ 返回nrpe版本说明安装没问题。
＃ 查看启动端口
[root@wiki ~]# netstat -tunlp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 0.0.0.0:5666 0.0.0.0:* LISTEN 27387/nrpe
如果有防火墙应该开放5666端口：
iptables -I eth0 -p tcp -m tcp �Cdport 5666 -j ACCEPT
windows被监控机的安装
下载NSClient++-Win32-0.3.6.msi
进行安装
到安装目录打开NSC.ini文件进行修改：
C:\Program Files\NSClient++\NSC.ini
编辑NSC.ini文件
在[modules]模块，将除CheckWMI.dll和RemoteConfiguration.dll外的所有dll文件名前的注释（;)去掉。
在[Settings]模块可以设置一个连接密码password=PWD，为了简单，在此不设密码。设置 allowed_hosts=127.0.0.1/32,192.168.0.216，可以连接的监控服务器的地址，如果写成192.168.0.0 /24则表示该子网内的所有机器都可以访问；如果这个地方是空白则表示所有的主机都可以连接上来（注意在[NSClient]有 allowed_hosts的同样设置，不要设置错了），最后不要忘记去掉前面的注释符（;）。
运行nsclient＋＋
cd C:\Program Files\NSClient++
NSClient++ /start （也可以在服务管理器中去启动、重启NSClientpp）
如果有防火墙，请开放相应端口。
创建监控配置文件，使用check_nt命令监控windows系统信息（此命令默认已定义）。
到此位置被监控机的安装也已经都完成了
7.检查nagios的所有配置文件并启动nagios

看到上面的提示就表示都ok了，如果有问题就按照提示一一调整，切记nagios的大部分配置文件里不支持空格尽量用TAB键来相隔，下面我们来重启nagios
service nagios restart
打开浏览器输入网址就可以访问nagios了
http://192.168.0.216/nagios/
输入用户名 test
密码 密码
现在我们就看到nagios的监控页面了，并且如果出现问题是可以发邮件和短信报警的了！！
到此配置基本结束，当然nagios是相当强大的这里只是发挥了一小部分的功能。如果大家对nagios感兴趣请下载官方文档
