一.安装依赖包

[root@Nagios ~]# yum install -y httpd php[root@Nagios ~]# yum install -y gcc glibc glibc-common[root@Nagios ~]# yum install -y gd gd-devel[root@Nagios ~]# yum install -y perl ntp unzip[root@Nagios ~]# yum install -y openssl-devel[root@Nagios ~]# /etc/init.d/ntpd start[root@Nagios ~]# chkconfig ntpd on[root@Nagios ~]# /usr/sbin/useradd -m nagios[root@Nagios ~]# passwd nagios[root@Nagios ~]# /usr/sbin/groupadd nagcmd[root@Nagios ~]# /usr/sbin/usermod -a -G nagcmd nagios[root@Nagios ~]# /usr/sbin/usermod -a -G nagcmd apache[root@Nagios ~]# id nagiosuid=500(nagios) gid=500(nagios) groups=500(nagios),501(nagcmd)[root@Nagios ~]# id apacheuid=48(apache) gid=48(apache) groups=48(apache),501(nagcmd)

二.nagios的安装

[root@Nagios ~]# cd /usr/local/src[root@Nagios src]# wget http://nagios-plugins.org/download/nagios-plugins-2.1.1.tar.gz[root@Nagios src]# wget https://assets.nagios.com/downloads/nagioscore/releases/nagios-4.1.1.tar.gz[root@Nagios src]# tar zxvf nagios-4.1.1.tar.gz[root@Nagios src]# cd nagios-4.1.1[root@Nagios nagios-4.1.1]# ./configure --prefix=/usr/local/nagios --with-comand-group=nagcmd[root@Nagios nagios-4.1.1]# make all[root@Nagios nagios-4.1.1]# make install[root@Nagios nagios-4.1.1]# make install-init[root@Nagios nagios-4.1.1]# make install-config[root@Nagios nagios-4.1.1]# make install-commandmode[root@Nagios nagios-4.1.1]# make install-webconf

三.nagios plugins的安装

[root@Nagios src]# tar xzf nagios-plugins-2.1.1.tar.gz [root@Nagios src]# cd nagios-plugins-2.1.1[root@Nagios nagios-plugins-2.1.1]# ./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group=nagios[root@Nagios nagios-plugins-2.1.1]# make && make install

四.nrpe插件安装

[root@Nagios src]# wget http://nchc.dl.sourceforge.net/project/nagios/nrpe-2.x/nrpe-2.15/nrpe-2.15.tar.gz[root@Nagios src]# tar zxf nrpe-2.15.tar.gz [root@Nagios src]# cd nrpe-2.15[root@Nagios nrpe-2.15]# ./configure --prefix=/usr/local/nagios[root@Nagios nrpe-2.15]# make all[root@Nagios nrpe-2.15]# make install-plugin[root@Nagios nrpe-2.15]# make install-daemon[root@Nagios nrpe-2.15]# make install-daemon-config# 测试启动# /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d# 自带了启动脚本[root@Nagios nrpe-2.15]# cp -rf init-script.in /etc/init.d/nrpe[root@Nagios nrpe-2.15]# chmod a+x /etc/init.d/nrpe [root@Nagios ~]# /etc/init.d/nrpe start

注:其实nagios获取信息都是靠/usr/local/nagios/libexec/check_nrpe 这个脚本主动获取nrpe服务端信息

五.配置并启动服务

[root@Nagios ~]# vi /usr/local/nagios/etc/objects/contacts.cfgdefine contact{    contact_name          nagiosadmin           use               generic-contact         alias              Nagios Admin          email              ca0gu0@126.com     }[root@Nagios ~]# vi /usr/local/nagios/etc/objects/commands.cfg    define command{    command_name  check_nrpe    command_line  $USER1$/check_nrpe -H "$HOSTADDRESS$" -c "$ARG1$"}    [root@Nagios ~]# htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin# 检查配置文件是否正确[root@Nagios ~]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg[root@Nagios ~]# chkconfig nagios on[root@Nagios ~]# service nagios start[root@Nagios ~]# chkconfig nrpe on[root@Nagios ~]# /etc/init.d/nrpe start[root@Nagios ~]# chkconfig httpd on[root@Nagios ~]# service httpd start[root@Nagios ~]# touch /var/www/html/index.html
