nagios安装配置

nagios官网上2013-10-15更新了最新版nagios-4.0.1

下载地址：

一、安装

下载后解压并安装

$ tar zxvf nagios-4.0.1.tar.gz 

$ cd nagios-4.0.1/

$ ./configure --prefix /home/nagios/nagios

$ make all

$ make install


# make install-init(需root)   

$ make install-commandmode

$ make install-config

# make install-webconf(需root)

安装Nagios 插件

$ tar zxvf nagios-plugins-1.5.tar.gz

$ cd nagios-plugins-1.5/

$ ./configure --prefix /home/nagios/nagios

$ make && make install

二、配置web登陆

配置/etc/httpd/conf/httpd.conf文件，在文件最后加入以下代码

#setting for nagios 
ScriptAlias /nagios/cgi-bin "/home/nagios/nagios/sbin"
<Directory "/home/nagios/nagios/sbin">
     AuthType Basic
     Options ExecCGI
     AllowOverride None
     Order allow,deny 
     Allow from all 
     AuthName "Nagios Access"
     AuthUserFile /home/nagios/nagios/etc/htpasswd.user
     Require valid-user
</Directory>
Alias /nagios "/home/nagios/nagios/share"
<Directory "/home/nagios/nagios/share">
     AuthType Basic
     Options None
     AllowOverride None
     Order allow,deny 
     Allow from all 
     AuthName "nagios Access"
     AuthUserFile /home/nagios/nagios/etc/htpasswd.user
     Require valid-user
</Directory>

创建以上配置文件中的/home/nagios/nagios/etc/htpasswd.user文件

$ htpasswd -c /home/nagios/nagios/etc/htpasswd.user <username>

将nagios的share目录链接到/var/www/html/nagios

# ln -s /home/nagios/nagios/share /var/www/html/nagios

启动nagios服务

# service nagios restart

验证nagios web是否配置成功,登陆http://x.x.x.x/nagios/，输入刚才设置的用户名密码

如果碰到“Error: Could not read object configuration data!”,检查是否启动nagios服务

三、安装nagios nrpe插件

解压编译安装

$ tar zxvf nrpe-2.15.tar.gz
$ cd nrpe-2.15/
$ ./configure --prefix /home/nagios/nagios
$ make all
$ make install-plugin
$ make install-daemon
$ make install-daemon-config
# make install-xinetd（需root）

在ubuntu下安装的时候，显示error:cannot find ssl libraries错误

需要安装openssl 并使用下面参数

$ ./configure --with-ssl=/usr/bin/openssl --with-ssl-lib=/usr/lib/x86_64-linux-gnu

添加到服务(需root)

在/etc/service文件中添加以下行

nrpe            5666/tcp        #nrpe

并修改/etc/xinetd.d/nrpe文件中的only_from项,加入nagios主机的ip,空格隔开

验证是否安装成功

# service xinetd restart
Stopping xinetd:                                          [  OK  ]
Starting xinetd:                                          [  OK  ]

#netstat -an |grep 5666
tcp        0      0 172.16.3.100:56661          172.16.3.110:9000           TIME_WAIT   
tcp        0      0 :::5666                     :::*                        LISTEN      

#../nagios/libexec/check_nrpe -H localhost
NRPE v2.15

看到版本号说明已经安装成功

被监控机要安装angios-plugin和nrpe-daemon,因为的home目录是用的nfs所以,就装在一起就好了

但是/etc/service和/etc/xinetd.d/nrpe文件还是要在每台被监控主机上修改

基本安装就到这里,剩下的就是修改配置文件了
