nagios、nrpe 在centsos 和ubuntu 环境下的编译安装

nagios 的编译安装

yum install httpd php  gcc glibc glibc-common gd gd-devel  openssl openssl-devel  -y

ubuntu 安装openssl-devel 是

apt-get 无法安装 openssl-devel请执行：  sudo apt-get install openssl apache2 php gcc glibc glibc-common gb gd-devel

sudo apt-get install libssl-dev

/usr/sbin/useradd -M  -s /sbin/nologin  nagios

mkdir -p /opt/nagios_install_packages

cd /opt/nagios_install_packages

wget http://softlayer-dal.dl.sourceforge.net/project/nagios/nagios-4.x/nagios-4.0.1/nagios-4.0.1.tar.gz

wget https://www.nagios-plugins.org/download/nagios-plugins-1.5.tar.gz

# nagios

tar -xf nagios-4.0.1.tar.gz

cd nagios-4.0.1

./configure --prefix=/usr/local/nagios

make all

make install

make install-init

make install-config

make install-commandmode

make install-webconf

htpasswd -c -m  /usr/local/nagios/etc/htpasswd nagios

service httpd restart

cd /opt

# plugins

tar -xf nagios-plugins-1.5.tar.gz

cd nagios-plugins-1.5

./configure --prefix=/usr/local/nagios/

make

make install

chkconfig --add nagios

chkconfig nagios on

service nagios start

-------------------------------------------------------------------

nrpe 的编译安装

#nrpe 的下载http://sourceforge.net/projects/nagios/files/nrpe-2.x/

wget  http://sourceforge.net/projects/nagios/files/nrpe-2.x/nrpe-2.15/nrpe-2.15.tar.gz/download?use_mirror=hivelocity&r=&use_mirror=hivelocity

nrpe 在被监控服务端的安装

服务器监控：nrpe监控客户端安装

注：安装过程需要有root用户权限，关闭主机防火墙（或者开放5666端口）。

所需软件包：nagios-plugins-1.5.tar.gz

　　nrpe-2.15.tar.gz

安装环境说明：

　　nagios监控端IP：192.168.0.10

　　nrpe监控客户端IP：192.168.0.20

1、添加nagios用户

useradd nagios -s /sbin/nologin -M

注意：在ubuntu 中这样添加用户 useradd nagios -M -s /usr/sbin/nologin

2、安装过程

安装nrpe

tar zxvf nrpe-2.15.tar.gz

cd nrpe-2.15

./configure --prefix=/usr/local/nrpe --enable-command-args

#make all

#make install-plugin

#make install-daemon

#make install-daemon-config

***以上安装完成后会在/usr/local/nrpe目录下产生bin、etc、libexec三个目录***

注意在ubuntu 下：

./configure --prefix=/usr/local/nrpe --enable-command-args  --with-ssl=/usr/bin/openssl --with-ssl-lib=/usr/lib/x86_64-linux-gnu

安装nagios插件

tar zxvf nagios-plugins-1.5.tar.gz

cd nagios-plugins-1.5

./configure --prefix=/usr/local/nrpe

make && make install

***以上安装完成后会在/usr/local/nrpe目录下产生libexec、share两个目录***

3、修改nrpe.cfg配置文件

allowed_hosts=127.0.0.1, 192.168.0.10

dont_blame_nrpe=1

定义命令，如：

command[check_tcp]=/usr/local/nrpe/libexec/check_tcp -p $ARG1$ -w $ARG2$ -c $ARG3$

4、修改目录/文件权限

chown -R nagios.nagios /usr/local/nrpe

5、启动nrpe守护进程

/usr/local/nrpe/bin/nrpe -c /usr/local/nrpe/etc/nrpe.cfg -d

6、nagios监控端测试nrpe是否安装成功

/usr/local/nagios/libexec/check_nrpe -H 192.168.0.20

如果返回“NRPE v2.15”即为已安装成功并启动

-------------------------------------------------------------------------

nrpe 在nagios 服务器器端的安装

tar zxvf nrpe-2.5.tar.gz

cd nrpe-2.5

./configure

make && make install-plugin

/usr/local/nagios/libexec/check_nrpe -H 被监控主机的IP

NRPE V.2.5
