nagios安装

Posted 2020-07-24

环境：vmware workstation虚拟机，server：192.168.118.128  

 

server环境：centos-6.6 nagios-4.1.1  httpd-2.4.20  php-5.6.22

 

 

server安装：

   useradd nagios  创建用户

   mkdir /usr/local/nagios
   chown -R nagios:nagios /usr/local/nagios

   tar -xzvf nagios-4.1.1.tar.gz.gz 
   cd nagios-4.1.1
   ll
   ./configure --prefix=/usr/local/nagios
   make all
   yum install unzip
   make all
   make install
   make install-init
   make install-commandmode
   make install-config
   chkconfig --add nagios
   chkconfig --level 35 nagios on
   chkconfig --list nagios
   cd ..
   rz
   ll
   tar -xzvf nagios-plugins-2.1.1.tar.gz #插件安装包
   tar -xzvf nagios-cn-3.2.3.tar.bz2 
   ll
   rm nagios-cn-3.2.3.tar.bz2
   ll
   rz
   ll
   tar -jxvf nagios-cn-3.2.3.tar.bz2   #汉化安装包
   cd nagios-cn-3.2.3
   ll
   ./configure 
   make all
   make install
   cd ..

   mkdir /usr/local/apache2
   tar -zxvf httpd-2.4.20.tar.gz

   make 
   make install
   cd ..
   ll
   tar -zxvf php-5.6.22.tar.gz 
   mkdir /usr/local/php
   cd php-5.6.22
   ./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2/bin/apxs 
   yum install libxml2
   find / -name libxml2
   find / -name libxml2*
   find / -name xml2-config
   yum install libxml2-devel
   find / -name xml2-config
   ./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2/bin/apxs
   make
   make test
   make install
   cp php.ini-development /usr/local/lib/php.ini  #php配置
   

　　

配置apache，文件位置：usr/local/apache2/conf/http.conf

将进程启动用户改为nagios，即：

User  nagios

Group nagios

LoadModule php5_module        modules/libphp5.so  # 去掉此行前面注释

找到DirectoryIndex 增加 index.php

并新增SetHandler application/x-httpd-php 使其支持解析php

在最后新增nagios配置：

ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"
<Directory "/usr/local/nagios/sbin">
     AuthType Basic
     Options ExecCGI
     AllowOverride None
     Order allow,deny
     Allow from all
     AuthName "Nagios Access"
     AuthUserFile /usr/local/nagios/etc/htpasswd
     Require valid-user
</Directory>
Alias /nagios "/usr/local/nagios/share"
<Directory "/usr/local/nagios/share">
     AuthType Basic
     Options None
     AllowOverride None
     Order allow,deny
     Allow from all
     AuthName "nagios Access"
     AuthUserFile /usr/local/nagios/etc/htpasswd
     Require valid-user
</Directory>

因为指定了访问验证文件，所以需要创建一个：

/usr/local/apache2/bin/htpasswd -c /usr/local/nagios/etc/htpasswd 【登录用户名自己设置】回车后输入设置的密码即可

 

设置完成可以启动nagios和apache了

 

出现的问题：

本地可访问，局域网内其他主机不可访问，报no router，此时是防火墙挡住了，可以关掉server防火墙：service iptables stop 或者新增一条放开监听端口80（http.conf）的规则：iptables -I INPUT -p tcp --dport 80 -j ACCEPT

到此server安装完成，当然为了监控其他主机还需要配置相应的nagios文件。
