LAMP或者LNMP
nagios-3.3.1.tar.gz-------------主程序
nagios-plugins-1.4.15.tar.gz----插件
2.安裝nagios-3.3.1.tar.gz
添加、修改用戶以及組
[root@localhost nagios]# useradd nagios
[root@localhost nagios]# useradd apache
[root@localhost nagios]# passwd nagios
[root@localhost nagios]# groupadd nagcmd  //創建用戶組用於Web接口執行外部命令
[root@localhost nagios]# usermod -g nagcmd nagios
[root@localhost nagios]# usermod -g nagcmd apache
[root@localhost monitor]# tar zxvf nagios-3.3.1.tar.gz -C /usr/local/src/
[root@localhost monitor]# tar zxvf nagios-plugins-1.4.15.tar.gz -C /usr/local/src/
[root@localhost monitor]# cd /usr/local/src/nagios
[root@localhost nagios]# ./configure --prefix=/usr/local/nagios --with-nagios-user=nagios
--with-nagios-group=nagios --with-command-group=nagcmd --with-gd-lib=/usr/lib/ --with-gd-inc=/usr/include/

[root@localhost nagios]# make all
[root@localhost nagios]# make install
[root@localhost nagios]# make install-init
[root@localhost nagios]# make install-config
[root@localhost nagios]# make install-commandmode
[root@localhost nagios]# vi /usr/local/nagios/etc/objects/contacts.cfg修改email地址以接收報警內容
[root@localhost nagios]# make install-webconf
/usr/bin/install -c -m 644 sample-config/httpd.conf /etc/httpd/conf.d/nagios.conf
/usr/bin/install: 無法創建普通文件"/etc/httpd/conf.d/nagios.conf": 沒有那個文件或目錄

[root@localhost nagios]# mkdir -p /etc/httpd/conf.d/
[root@localhost nagios]# /usr/local/webserver/apache/bin/htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
3.安裝nagios插件
[root@localhost nagios]# cd ../nagios-plugins-1.4.15/
[root@localhost nagios-plugins-1.4.15]# ./configure --with-nagios-user=nagios --with-nagios-group=nagios
配置成功後有如下提示：
--with-apt-get-command:
--with-ping6-command: /bin/ping6 -n -U -w %d -c %d %s
--with-ping-command: /bin/ping -n -U -w %d -c %d %s
--with-ipv6: yes
--with-mysql: /usr/bin/mysql_config
--with-openssl: yes
--with-gnutls: no
--enable-extra-opts: no
--with-perl: /usr/bin/perl
--enable-perl-modules: no
--with-cgiurl: /nagios/cgi-bin
--with-trusted-path: /bin:/sbin:/usr/bin:/usr/sbin
--enable-libtap: no
[root@bogon nagios-plugins-1.4.15]# make[root@bogon nagios-plugins-1.4.15]# make install
驗證Nagios配置文件
[root@bogon nagios]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg啓動Nagios服務[root@bogon nagios]# service nagios start4.編輯apache的httpd.conf
在最後添加：ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"
<Directory "/usr/local/nagios/sbin">
#  SSLRequireSSL
Options ExecCGI
AllowOverride None
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
</Directory>
Alias /nagios "/usr/local/nagios/share"
<Directory "/usr/local/nagios/share">
#  SSLRequireSSL
Options None
AllowOverride None
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
</Directory>
5.再驗證下
[root@bogon nagios]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg沒有出錯的話，重新啓動nagios和apache
6.登錄web頁面
http://localehost/nagios
輸入剛纔設置的用戶名密碼。
