nagios3.2 安装笔记

 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

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 

<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>

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
