CentOS环境下Nagios的安装与配置

环境准备

在开始安装Nagios之前，我们需要确保以下几点：

1、系统已经安装了CentOS操作系统。

2、系统已经安装了EPEL源，因为Nagios的软件包位于EPEL源中，可以通过以下命令安装EPEL源：

sudo yum install epel-release

3、确保系统已经安装了必要的开发工具，如gcc、make等，可以通过以下命令安装：

sudo yum groupinstall "Development Tools"

安装Nagios

1、下载Nagios的源码包，访问Nagios官网(https://www.nagios.com/)获取最新版本的源码包，或者直接使用以下命令下载：

wget https://downloads.sourceforge.net/project/nagios/ nagios-版本号.tar.gz

2、解压源码包：

tar xzf nagios-版本号.tar.gz

3、进入解压后的目录：

cd nagios-版本号

4、配置并安装Nagios:

sudo ./configure --with-command-group="network-agent" --with-esxlibdir=/usr/lib/vmware/bin --with-esxaddr=http://localhost:443/sdk --with-syslogd-runlevel=daemon --with-debug=false --prefix=/usr/local/nagios --enable-server --enable-client --with-nagiosuser="nagios" --with-nagiosgroup="nagios" --with-pgmcache-type="file" --with-pgmcache-path=/tmp/pgmcache --with-pam --with-authdir=/etc/nagios --with-userdir=/var/lib/nagios/rw --with-groupdir=/var/lib/nagios/rw/nagios --with-ssl=no --enable-hostd-checkmkd --enable-proxycheck --enable-ipad --enable-win2kgui --enable-win32gui --enable-ipv6 --with-tnsnamesorcl="localhost"

配置Nagios

1、创建Nagios用户和组：

sudo groupadd nagios
sudo useradd -g nagios -m nagios -d /var/lib/nagios -s /sbin/nologin nagiosuser

2、创建Nagios配置目录：

sudo mkdir -p /etc/nagios /var/lib/nagios /var/log/nagios /usr/local/nagios/rw/varlib_nagiosstatefiles_volatile /usr/local/nagios/rw/varlib_nagiosstatefiles_backup /usr/local/nagios/rw/data /usr/local/nagios/rw/config /usr/local/nagios/rw/plugins /usr/local/nagios/rw/commandscripts /usr/local/nagios/rw/webfrontends /usr/local/nagios/rw/htdocs ~/.nagioscore ~/.nrpecontext ~/.cfg $HOME/nagiositemtry.cfg $HOME/nrpestatus.cfg $HOME/init.d $HOME/rc.d $HOME/systemd/*.service $HOME/*.conf $HOME/*.sh $HOME/*.py $HOME/*.txt $HOME/*.xml $HOME/*.yml $HOME/*.json $HOME/*.ini $HOME/*.csv $HOME/*.tpl $HOME/*.md $HOME/*.html $HOME/*.css $HOME/*.js $HOME/*.php $HOME/*.png $HOME/*.jpg $HOME/*.jpeg $HOME/*.gif $HOME/*.ico $HOME/*.svg $HOME/*.pdf $HOME/*.zip $HOME/*.tar $HOME/*.gz $HOME/*.bz2 $HOME/*.xz $HOME/*.7z $HOME/*.rar $HOME/*.zip $HOME/*.tar $HOME/*.gz $HOME/*.bz2 $HOME/*.xz $HOME/*.7z $HOME/*.rar $HOME/*.zip $HOME/*.tar $HOME/*.gz $HOME/*.bz2 $HOME/*.xz $HOME/*.7z $HOME/*.rar $HOME/*.zip $HOME/*.tar $HOME/*.gz $HOME/*.bz2 $HOME/*.xz $HOME/*.7z $HOME/*.rar $HOME/*.zip $HOME/*.tar $HOME/*.gz $HOME/*.bz2 $Home
