Nagios在Ubuntu server上的安装配置

时间：2021-01-29 09:06:01

首先我参看的是Nagios的官方文档，Nagios – Installing Nagios Core From Source——The Industry Standard in IT Infrastructure Monitoring，但是文档写的不够详细，对于安装的部分写的过于简略，缺少了几个步骤。

下面我将叙述详细步骤。

#首先安装必要的软件包：
sudo apt-get install wget build-essential apache2 php5-gd libgd2-xpm libgd2-xpm-dev libapache2-mod-php5

#下载软件包
cd /tmp
wget http://prdownloads.sourceforge.net/sourceforge/nagios/nagios-3.4.1.tar.gz
wget http://sourceforge.net/projects/nagiosplug/files/nagiosplug/1.4.15/nagios-plugins-1.4.15.tar.gz

#添加组和用户
useradd nagios
groupadd nagcmd
usermod -a -G nagcmd nagios

#解压缩
tar zxvf nagios-3.4.1.tar.gz
tar zxvf nagios-plugins-1.4.15.tar.gz

cd nagios
./configure --with-nagios-group=nagios --with-command-group=nagcmd -–with-mail=/usr/bin/sendmail

cd /tmp/nagios-plugins-1.4.15
./configure --with-nagios-user=nagios --with-nagios-group=nagios

#安装
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

将下面的行加入apache配置文件/etc/apache2/httpd.conf的alias模块<IfModule alias_module>，因为我的httpd.conf文件为空，因此自行创建了该模块。

<IfModule alias_module>

    #

    # Redirect: Allows you to tell clients about documents that used to

    # exist in your server's namespace, but do not anymore. The client

    # will make a new request for the document at its new location.

    # Example:

    # Redirect permanent /foo http://localhost/bar

    #

    # Alias: Maps web paths into filesystem paths and is used to

    # access content that does not live under the DocumentRoot.

    # Example:

    # Alias /webpath /full/filesystem/path

    #

    # If you include a trailing / on /webpath then the server will

    # require it to be present in the URL.  You will also likely

    # need to provide a <Directory> section to allow access to

    # the filesystem path.

    #

    # ScriptAlias: This controls which directories contain server scripts.

    # ScriptAliases are essentially the same as Aliases, except that

    # documents in the target directory are treated as applications and

    # run by the server when requested rather than as documents sent to the

    # client.  The same rules about trailing "/" apply to ScriptAlias

    # directives as to Alias.

    #

	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>

</IfModule>

# 创建apache目录验证文件
htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
New password: (输入密码)
Re-type new password: (再输入一次密码)
Adding password for user nagiosadmin

# 重启apache：
service apache2 restart

# 检查Nagios配置文件
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

# 启动Nagios
service nagios start

在浏览器中打开http://<your.nagios.server.ip>/nagios。

Nagios主界面如下图：

登录时要求输入用户名密码，用户名是nagiosadmin，密码即为上面你自己设置的密码。
