一、創(chuàng)建nagios用戶和用戶組。
[root@localhost ~]#useradd -s /sbin/nologin nagios [root@localhost ~]#mkdir /usr/local/nagios [root@localhost ~]#chown -R nagios:nagios /usr/local/nagios
二、編譯安裝nagios
[root@localhost ~]# tar -zxvf nagios-3.5.0.tar.gz [root@localhost ~]# cd nagios [root@localhost nagios]#./configure --prefix=/usr/local/nagios [root@localhost ~]# tar -zxvf nagios-3.5.0.tar.gz [root@localhost ~]# cd nagios [root@localhost nagios]#./configure --prefix=/usr/local/nagios [root@localhost nagios]#make all [root@localhost nagios]#make install [root@localhost nagios]# make install-init #在/etc/rc.d/init.d目錄下創(chuàng)建nagios啟動腳本 [root@localhost nagios]# make install-config #安裝示例配置文件 [root@localhost nagios]# make install-commandmode #配置目錄權(quán)限
三、nagios目錄對應(yīng)功能說明:
bin：可執(zhí)行程序所在目錄
etc：配置文件所在目錄
sbin：cgi文件所在目錄，也就是執(zhí)行外部命令所需文件所在目錄
share：網(wǎng)頁文件所在目錄
libexec：外部插件所在目錄
var：日志文件，lock等文件所在目錄。修改日志文件時間格式，修改拷貝的文件(perl -i -pe '($t) = ($_ =~ m/^\[(\d+)\]/); $nice=scalar localtime $t; s/^\[(\d+)\]/[$nice]/' nagios.log)
var/archives：日志自動歸檔目錄
var/rw：用來存放外部命令文件的目錄
四、安裝nagios插件。
[root@localhost ~]# tar -zxvf nagios-plugins-1.4.16.tar.gz [root@localhost ~]# yum -y install openssl* [root@localhost ~]# cd nagios-plugins-1.4.16 [root@localhost nagios-plugins-1.4.16]# ./configure --prefix=/usr/local/nagios [root@localhost nagios-plugins-1.4.16]# make [root@localhost nagios-plugins-1.4.16]# make install
五、安裝并配置httpd和php
[root@localhost ~]# yum -y install php httpd
[root@localhost ~]# vim /etc/httpd/conf/httpd.conf
User nagios
Group nagios
DirectoryIndex index.html index.html.var index.php
AddType application/x-httpd-php .php
ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"
<Directory "/usr/local/nagios/sbin">
AuthType Basic
options ExecCGI
AllowOverride None
Order allow,deny
Allow from all
AuthName "Nagios Access"
AuthUserFile /usr/local/nagios/etc/htpasswd
Require valid-user
</Directory>
Alias /nagios "/usr/local/nagios/share"
<Directory "/usr/local/nagios/share">
AuthType Basic
Options None
AllowOverride None
Order allow,deny
Allow from all
AuthName "Nagios Access"
AuthUserFile /usr/local/nagios/etc/htpasswd
Require valid-user
</Directory>
[root@localhost ~]# htpasswd -cm /usr/local/nagios /etc/htpasswd USER
[root@localhost ~]# service httpd restart
[root@localhost ~]# service nagios restart
#訪問http://ip/nagios 輸入用戶/密碼就可以看到nagios管理界面六、安裝插件NRPE

command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}
[root@localhost libexec]# ./check_nrpe -H 192.168.1.1 #檢查與被監(jiān)控對象的連通性七、定義被監(jiān)控主機(jī)和服務(wù)。
