由于需要用Nagios+Ganglia监控Hadoop集群,所以这里开始了Nagios+Ganglia的旅程.Nagios官网上资料已经很详尽,但在Ubuntu上安装Nagios方面,只停留在Ubuntu 6.10和Ubuntu 7.10版本.而在Ubuntu11.10或Ubuntu10.04上安装有些错误,所以这里记录下来.具体可以查看Nagios官网上Nagios在Ubuntu上安装说明:http://nagios.sourceforge.net/docs/3_0/quickstart-ubuntu.html

1.所依赖包:

1)Apache #必须安装

2)Php #必须安装

3)Gcc #必须安装

4)Gd #必须安装

5) mailx #可选,让Nagios支持邮件

6) postfix #可选,让Nagios支持邮件

以上可以通过dpkp -L apache2等查看,如未安装,请通过sudo apt-get install apache2等安装,具体如下:

sudo apt-get install apache2 # 安装Apache

sudo apt-get install php5 # 安装Php

sudo apt-get install libapache2-mod-php5 # 整合Apache+Php

sudo apt-get install build-essential # 安装Ubuntu编译内核

sudo apt-get install libgd2-xpm-dev # 安装Gd

sudo apt-get install mailx

sudo apt-get install postfix

2.开始安装

sudo -s # 切换到root

1) 设置好用户和用户组

/usr/sbin/useradd -m -s /bin/bash nagios # 添加用户nagios

passwd nagios # 给新用户nagios设置密码

/usr/sbin/groupadd nagios # 添加用户组nagios

/usr/sbin/usermod -G nagios nagios # 将新用户nagios添加到用户组nagios

/usr/sbin/groupadd nagcmd # 添加新的用户组nagcmd,用于接受外部命令,如通过web

/usr/sbin/usermod -a -G nagcmd nagios # 添加用户nagios到用户组nagcmd

/usr/sbin/usermod -a -G nagcmd www-data # 添加apache用户到用户组nagcmd

2)下载nagios和nagios-plugin

mkdir ~/downloads

cd ~/downloads

wget http://nchc.dl.sourceforge.net/project/nagiosplug/nagiosplug/1.4.15/nagios-plugins-1.4.15.tar.gz # 下载插件

wget http://nchc.dl.sourceforge.net/project/nagios/nagios-3.x/nagios-3.3.1/nagios-3.3.1.tar.gz #下载nagios

3)安装Nagios

cd ~/downloads

tar xzf nagios-3.3.1.tar.gz

cd nagios

./configure --with-command-group=nagcmd

make all

#make install #使用该命令会报错,替换成以下命令

./configure --with-command-group=nagcmd

sed -i 's:for file in includes/rss/\*;:for file in includes/rss/\*.\*;:g' ./html/Makefile

sed -i 's:for file in includes/rss/extlib/\*;:for file in includes/rss/extlib/\*.\*;:g' ./html/Makefile

make fullinstall

#以上避免了使用make install报错,报错内容查看博客结尾.具体原因不清楚,有知道的麻烦回帖告知.

make install-init #安装初始化,貌似make fullinstall有了安装,但无所谓

make install-config #安装配置

make install-commandmode #安装命令模式

4)自定义配置

vi /usr/local/nagios/etc/objects/contacts.cfg #在里面修改,如email

5)安装web接口,以便通过浏览器可以访问到nagios

make install-webconf

htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin #给nagios设置用户和密码

/etc/init.d/apache2 reload #重载,让新设置的用户和密码生效

6)编译nagios插件

cd ~/downloads

tar xzf nagios-plugins-1.4.15.tar.gz

cd nagios-plugins-1.4.15

./configure --with-nagios-user=nagios --with-nagios-group=nagios

make

make install

7)启动nagios

ln -s /etc/init.d/nagios /etc/rcS.d/S99nagios #让nagios随机启动

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg #验证naios配置文件是否正确

/etc/init.d/nagios start #启动nagios

8)通过浏览器进入nagios控制台

http://localhost/nagios/ #再输入刚配置的用户nagiosadmin和你设置的密码

最后附上用make install安装nagios时所报错误
