linux nagios安装配置

安装系统：redhat linux as 4 2.6.9

:nagios 监控安装配置

准备软件： nagios-2.6.tar.gz  nagios-plugins- 1.4.9 .tar.gz

Linux 安装完系统后默认是可以发送邮件的。（我在安装系统的时候开启了 mail 服务，以及安装了开发环境软件）

（ 1 ）：添加 nagios 用户及组

[root@linux etc]# groupadd nagios

[root@linux etc]# useradd -g nagios -d /usr/local/nagios -s /bin/false nagios

（ 2 ）：解压，安装 nagios

[root@linux nagios]# tar zxvf nagios-2.6.tar.gz

[root@linux nagios-2.6]# ./configure --prefix=/usr/local/nagios

[root@linux nagios-2.6]# make all

[root@linux nagios-2.6]# make install

[root@linux nagios-2.6]# make install-init

[root@linux nagios-2.6]# make install-commandmode

[root@linux nagios-2.6]# make install-config

安装 nagios 的插件

[root@linux nagios]# tar zxvf nagios-plugins- 1.4.9 .tar.gz

[root@linux nagios-plugins- 1.4.9 ]# ./configure --prefix=/usr/local/nagios/

( 在 redhat 系统上面安装可能出现 configure 时，到这里 checking for redhat spopen problem... 就不动了，所以需要在 configure 时再加上这个 --enable-redhat-pthread-workaround )

[root@linux nagios-plugins- 1.4.9 ]# make

[root@linux nagios-plugins- 1.4.9 ]# make install

（ 3 ）：配置 apache

配置 apache 的匿名访问：

[root@linux conf.d]# touch nagios.conf  | vi nagios

 [root@linux apache]# ./bin/htpasswd -c /usr/local/apache/conf.d/htpasswd nagiosadmin

启动 apache 测试，访问   [url]http://apache-ip/nagios[/url]

入禁止访问：将 apache 的用户和组改为 nagios 。。

如果认证无法通过的话，就查看 apache 的错误日志，如果出现 MySQL ERROR: Table 'test.user_info' doesn't exist: /nagios 的提示，就把 http 下的 auth_mysql.conf 配置文件该了。不让 apache 进行 mysql 认证。

（ 4 ）：配置 nagios

[root@linux etc]# cp cgi.cfg-sample cgi.cfg

[root@linux etc]# cp commands.cfg-sample commands.cfg

[root@linux etc]# cp nagios.cfg-sample nagios.cfg

[root@linux etc]# cp resource.cfg-sample resource.cfg

[root@linux etc]# vi nagios.cfg

#cfg_file=/usr/local/nagios/etc/localhost.cfg 关闭

开启

cfg_file=/usr/local/nagios/etc/contactgroups.cfg

cfg_file=/usr/local/nagios/etc/contacts.cfg

cfg_file=/usr/local/nagios/etc/dependencies.cfg 此配置文件可以提供先前条件，比如当 sina 通的情况下，测试业务服务器状态。

cfg_file=/usr/local/nagios/etc/hostgroups.cfg

cfg_file=/usr/local/nagios/etc/hosts.cfg

cfg_file=/usr/local/nagios/etc/services.cfg

cfg_file=/usr/local/nagios/etc/timeperiods.cfg

command_check_interval=10s

[root@linux etc]# touch contactgroups.cfg

[root@linux etc]# touch contacts.cfg

[root@linux etc]# touch hostgroups.cfg

[root@linux etc]# touch hosts.cfg

[root@linux etc]# touch services.cfg

[root@linux etc]# touch timeperiods.cfg

[root@linux etc]# vi cgi.cfg

配置完后测试配置是否成功：

服务器的配置文件已复制出来备份。随本文档查看。

[root@linux etc]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

出现： Total Warnings: 0

Total Errors:   0

 

Things look okay - No serious problems were detected during the pre-flight check

如果配置有错误，可以参考 localhost.cfg

表示成功。然后启动：

[root@linux etc]# /usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg

然后用 ie 查看结果：
