偶看新闻杂兵的绝望攻略:nagios plugin yum 安装方法.(未完）
来源：百度文库 编辑：偶看新闻 时间：2024/04/25 06:14:19
1.首先确保yum源头可从该站点更新相关yum安装包:http://download.fedora.redhat.com/pub/epel/5/i386/
#rpm -ivh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm
直接安装即可.
[root@bogon etc]# rpm -ivh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm

2.nagios server版本:centos 5.5
3.进入root账号下:
切换为root用户
su -l
创建新帐户名为nagios并给它一个登录口令
/usr/sbin/useradd nagios
passwd nagios
创建一个用户组名为nagios，并把nagios帐户加入该组
/usr/sbin/groupadd nagios
/usr/sbin/usermod -G nagios nagios
创建一个用户组名为nagcmd来执行外部命令并可以通过WEB接口来执行。将nagios用户和apache用户都加到这个组中。
/usr/sbin/groupadd nagcmd
/usr/sbin/usermod -G nagcmd nagios
/usr/sbin/usermod -G nagcmd apache
4.进入系统,root下:
root#
[root@bogon etc]# yum install httpd gcc glibc glibc-common gd gd-devel nagios nagios-plugins nrpe （后期添加：nagios-plugins-all nagios-common）

4.这个时候由于iptable没有开启tcp80端口，apache不可访问。
开启iptable的http端口。
5.登录http://ipaddress/
6.登录http://192.168.1.23/nagios，发现无法正常访问。一般是由于访问权限不够造成。
7.编辑访问权限，如下：
[root@bogon conf.d]# pwd
/etc/httpd/conf.d
[root@bogon conf.d]# vi nagios.cfg
ScriptAlias /nagios/cgi-bin/ /usr/lib/nagios/cgi-bin/
Options ExecCGI
order deny,allow
deny from all
allow from 127.0.0.1
AuthType Basic
AuthUserFile /etc/nagios/passwd
AuthName "nagios"
require valid-user
Alias /nagios/ /usr/share/nagios/html/
Options None
order deny,allow
deny from all
allow from 127.0.0.1
AuthType Basic
AuthUserFile /etc/nagios/passwd
AuthName "nagios"
require valid-user
# For SSL-servers
#
# Options ExecCGI
# SSLRequireSSL
# order deny,allow
# deny from all
# allow from 127.0.0.1
# AuthType Basic
# AuthUserFile /etc/nagios/passwd
# AuthName "nagios"
# require valid-user
#
#
#Alias /nagios/ /usr/share/nagios/html/
#
# Options None
# SSLRequireSSL
# order deny,allow
# deny from all
# allow from 127.0.0.1
# AuthType Basic
# AuthUserFile /etc/nagios/passwd
# AuthName "nagios"
# require valid-user
#
将上面的
deny from all
改为：allow from all
再wq保存退出。
8.编辑访问密码，由上图可以看出用户密码保存在
/etc/nagios/passwd 中。设定密码：#htpasswd –c /etc/nagios/passwd/htpasswd.users nagiosadmin
9.登录web界面：http://192.168.1.23/nagios/
(注意：必须在nagios后面加“/”.否则登录失败）
然后弹出一个框。输入用户名：nagiosadmin和密码：nagiosadmin
若输入正确的用户名和密码依旧无法进入，则修改以下文件，确保认证密码对应正确的文件夹。
[root@bogon selinux]# cd /etc/httpd/conf.d/
[root@bogon conf.d]# ls
nagios.conf nagios.conf.rpmsave proxy_ajp.conf README squid.conf welcome.conf
[root@bogon conf.d]# more nagios.conf
ScriptAlias /nagios/cgi-bin/ /usr/lib/nagios/cgi-bin/
Options ExecCGI
order deny,allow
allow from all
allow from 127.0.0.1
AuthType Basic
AuthUserFile /etc/nagios/passwd
AuthName "nagios"
require valid-user
Alias /nagios/ /usr/share/nagios/html/
Options None
order deny,allow
allow from all
allow from 127.0.0.1
AuthType Basic
AuthUserFile /etc/nagios/passwd
AuthName "nagios"
require valid-user
# For SSL-servers
#
将AuthUserFile /etc/nagios/passwd 改为： AuthUserFile /etc/nagios/passwd/htpasswd.users
再次登录，出现以下界面，则显示成功，再点击“host detail”。会出现以下界面。
10.当出现上述界面，一般是由于“cgi.cfg中的use_authentication=1”造成，将1改成0可行。
----------------------------------------------------------------------------------------------------
摘录：http://tenhlf.blog.163.com/blog/static/5363158120100211105433/
所有的安装配置里面，都说将cgi.cfg的use_authentication=0，据说这样能够访问全部的页面。事实上，这是一个偷懒的做法，而且在以后必将会更正。
我们会在web页面对一些设置进行更改，在nagios的机制中，都会通过nagios.cmd。而use_authentication=0，会 disable external_command_file的使用，于是，所有更改都会提示authentication错误。
正确的做法，首先，将cgi.cfg的use_authentication=1，然后我们授权用户的权限。
authorized_for_system_information=*
authorized_for_configuration_information=*
authorized_for_system_commands=siemsen
authorized_for_all_services=*
authorized_for_all_hosts=*
authorized_for_all_service_commands=*
authorized_for_all_host_commands=*
*代表所有用户，也可以用逗号形式将用户逐一添入（推荐这种方法）。例如：
authorized_for_system_information=nagios,nagiosadmin,www-data,apacheuser
#======================以下没能测试，可能对源码安装方式有效
接着，要改变nagios.cmd所在目录/usr/local/nagios/var/rw的权限，命令如下。
chown nagios.nagiocmd /usr/local/nagios/var/rw
chmod u+rwx /usr/local/nagios/var/rw
chmod g+rwx /usr/local/nagios/var/rw
chmod g+s /usr/local/nagios/var/rw
最后重起nagios:
/etc/init.d/nagios restart
再去更新设置，就能成功了！
