【移动应用开发技术】nagios安装、配置、PNP与飞信报警

【移动应用开发技术】nagios安装、配置、PNP与飞信报警

一、创建nagios用户和用户组[root@localhost~]#useradd-s/sbin/nologinnagios[root@localhost~]#mkdir/usr/local/nagios[root@localhost~]#chown-Rnagios.nagios/usr/local/nagios二、开启系统sendmail服务[root@localhost~]#servicesendmailstart三、编译安装nagios[root@localhost~]#tar-zxvf

nagios-3.2.0.tar.gz[root@localhost~]#cdnagios-3.2.0[root@localhostnagios-3.2.0]#./configure--prefix=/usr/local/nagios#指定nagios的安装目录，这里指定nagios安装到/usr/local/nagios目录[root@localhostnagios-3.2.0]#makeall[root@localhostnagios-3.2.0]#makeinstall#makeinstall用来安装nagios的主程序,CGI和HTML文件[root@localhostnagios-3.2.0]#makeinstall-init#通过makeinstall-init命令可以在/etc/rc.d/init.d目录下创建nagios启动脚本[root@localhostnagios-3.2.0]#makeinstall-commandmode#通过makeinstall-commandmode命令来配置目录权限[root@localhostnagios-3.2.0]#makeinstall-config#makeinstall-cofig命令用来安装nagios示例配置文件,这里安装的路径是/usr/local/nagios/etcnagios安装完成后，目录对应的功能说明如下：bin：可执行程序所在目录etc：配置文件所在目录sbin：cgi文件所在目录，也就是执行外部命令所需文件所在目录share：网页文件所在目录libexec：外部插件所在目录var：日志文件，lock等文件所在目录var/archives：日志自动归档目录var/rw：用来存放外部命令文件的目录四、安装nagios的插件以nagios-plugins-1.4.14为例，插件版本与nagios版本关系并不大。[root@localhostnagios]#tar-zxvf

nagios-plugins-1.4.14.tar.gz[root@localhostnagios]#cd

nagios-plugins-1.4.14[root@localhostnagios-plugins-1.4.14]#./configure--prefix=/usr/local/nagios[root@localhostnagios-plugins-1.4.14]#make[root@localhostnagios-plugins-1.4.14]#makeinstall查看/usr/local/nagios/libexec，会看到新增很多的插件。五、安装Nagios中文化插件下载地址：/projects/nagios-cn/files/此处切忌版本要与nagios的版本对应。[root@localhost~]#tarjxvfnagios-cn-3.2.0.tar.bz2[root@localhostnagios-cn-3.2.0]#cdnagios-cn-3.2.0[root@localhostnagios-cn-3.2.0]#./configure[root@localhostnagios-cn-3.2.0]#makeall[root@localhostnagios-cn-3.2.0]#makeinstall六、配置httpd和php修改httpd的配置文件/etc/httpd/conf/httpd.conf找到如下两行UserapacheGroupapache#如果找不到，请通过搜索nobody寻找修改为UsernagiosGroupnagios然后找到DirectoryIndexindex.htmlindex.html.var修改为DirectoryIndexindex.htmlindex.html.varindex.php再在其下增加如下行AddTypeapplication/x-httpd-php.php在配置文件末尾增加如下信息：#settingfornagiosScriptAlias/nagios/cgi-bin"/usr/local/nagios/sbin"

<Directory"/usr/local/nagios/sbin">

AuthTypeBasic

OptionsExecCGI

AllowOverrideNone

Orderallow,deny

Allowfromall

AuthName"NagiosAccess"AuthUserFile/usr/local/nagios/etc/htpasswd

Requirevalid-user

</Directory>Alias/nagios"/usr/local/nagios/share"

<Directory"/usr/local/nagios/share">

AuthTypeBasic

OptionsNone

AllowOverrideNone

Orderallow,deny

Allowfromall

AuthName"nagiosAccess"AuthUserFile/usr/local/nagios/etc/htpasswd

Requirevalid-user

</Directory>保存配置文件七、新增验证文件[root@localhost]#/usr/bin/htpasswd-c/usr/local/nagios/etc/htpasswdyileiNewpassword:(输入密码)Re-typenewpassword:(再输入一次密码)Addingpasswordforuseryilei在/usr/local/nagios/etc下就会新增一个htpasswd验证文件。八、验证[root@localhost]#servicehttpdrestart[root@localhost]#servicenagiosstart通过浏览器输入http://ip/nagios/输入用户名/密码，就可以看到nagios的管理界面啦。此时看到的界面中没有任何监控机的信息。九、配置联系人1、修改contacts.cfg(联系人配置文件)definecontact{

contact_name

yilei

;Shortnameofuser

use

generic-contact

;Inheritdefaultvaluesfromgeneric-contacttemplate(definedabove)

alias

yileiAdmin

;Fullnameofuser

email

admin@

;<<*****CHANGETHISTOYOUREMAILADDRESS******

pager

158********

}联系人组definecontactgroup{

}十．配置主机和服务1.添加主机Vim
