nagios3.2 安装笔记

dsqzhaoyue

　　安装前的准备工作


nagios-3.2.0.tar.gz  nagios-cn-3.2.0.tar.bz2  nagios-plugins-1.4.14.tar.gz


apache  php




1. 为nagios服务建立用户及用户组，这里建立一个nagcmd的用户组，把nagios用户和Web执行用户都加入到这个组里：


useradd -m nagios && passwd nagios
groupadd nagcmd
usermod -a -G nagcmd nagios
usermod -a -G nagcmd apache


2.编译安装
apache编译安装
cd /home/src/http
tar zxvf httpd-2.2.11.tar.gz
mv httpd-2.2.11 http
cd http
./configure --prefix=/usr/local/apache2 --enable-so --with-mpm=worker --enable-cache  --enable-mem-cache --enable-disk-cache- -enable-proxy-balancer  --enable-proxy-ajp  --enable-proxy-http   --enable-proxy-ftp   --enable-proxy-connect  --enable-proxy    --enable-ssl   --enable-static-htpasswd --enable-charset-lite --enable-rewrite    --enable-vhost-alias  (可灵活选择，如无必要，模块使用越少则越安全,当然不包括安全模块等特殊模块。)
make&&make install
/usr/local/apache2/bin/apachectl -t start #启动apache
打开页测试ip:80显示it works表示成功。
##php5.3
./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache/bin/apxs --with-config-file-path=/usr/local/lib --with-gd=/usr/local/gd2 --with-libdir=lib64  --enable-track-vars --with-xml --with-mysql --with-zlib-dir=/usr/local
出错时Unable to find libgd.(a|so) anywhere under /usr/local/gd2
#cp /usr/local/gd2/lib/* /usr/local/gd2/

./configure --prefix=/usr/ local /apache2/htdocs/nagios --with-nagios-user=www --with-nagios-group=www --with- command-user=www --with- command -group=www --with-gd-lib=/usr/local /gd2/lib --with-gd-inc=/usr/ local /gd2/include --with-init- dir =/etc/init.d --with-httpd-conf=/usr/ local/apache2/conf/extra

[/table]

[table]

yum install gb gb-devel httpd php

tar zxvf nagios-3.2.0.tar.gz
./configure --prefix=/usr/local/nagios
make all
make install
安装主程序.CGI和HTML文件
make install-init
在/etc/rc.d/init.d目录下建立nagios的启动脚本
make install-commandmode
配置目录权限
make install-config
安装nagios的配置文件模板，默认路径是/usr/local/nagios/etc


tar jxvf nagios-plugins-1.4.14.tar.gz
插件版本号与主版本号关联不大
./configure --prefix=/usr/local/nagios
make && make install
安装完成后在/usr/local/nagios/libexec目录下,生成很多可执行文件

tar zxcf nagios-cn-3.2.0.tar.gz
下载地址:http://sourceforge.net/projects/nagios-cn/files/
./configure  --prefix=/usr/local/nagios
默认路径即为/usr/local/nagios所以这里可以不用添加
make all && make install

nagios 3.1.X以后版本需有PHP支持


3.配置apache和php
httpd.conf
----------------
修改
User apache
Group apache

Directoryindex index.php

AddType application/x-httpd-php .php

增加
ScriptAlias /nagios/cgi-bin /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  
   

Alias /nagios /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  



copy时应注意：
空格字符必须时英文半角
否则启动时启动时会报如下错误
Invalid command '\xe3\x80\x80\xe3\x80\x80', perhaps mis-spelled or defined by a module not included in the server configuration




4.对web目录作认证
htpasswd -c /usr/local/nagios/etc/htpasswd admin


5.启动apache
apachectl start

NRPE的部署

NagisoCore----plugin----Nrpe----|-----（SSL）------|----plugin(Ntclient++)---Nrpe

NRPE的安装
1.新建用户
useradd -s /usr/sbin/nolgin nagios

2.安装plugin
./configure --prefix=/usr/local/nagios&&make && make install

3.安装NRPE
./confugure --prefix=/usr/local/nagios
make all
make install-plugin
make install-daemon
make install-daemon-config

4.配置NRPE
vim  /usr/local/nagios/etc/nrpe.cfg
修改
server_address=127.0.0.1,192.168.10.99(本地)
allowed_address=127.0.0.1,192.168.10.234(远程)

5.启动守护进程
/usr/local/nagios/bin/nrpe -c /usr/loacl/nagios/etc/nrpe.cfg -d
可以将以上命令加入到rc.local开机自动启动

6.检查
netstat -antl |grep 5666

/usr/local/nagios/libexec/check_nrpe -H 127.0.0.1
