开始
[[email protected] Desktop] groupadd nagcmd
[[email protected] Desktop] useradd —G nagcmd nagios
[[email protected] Desktop] passwd nagios
[[email protected] Desktop] usermod -a -G nagcmd apache
解压文件
[[email protected] Desktop] cd nagios-4.1.1
[[email protected] nagios-4.1.1] ./configure --sysconfdir=/etc/nagios --with-command-group=nagcmd --enable-event-broker
[[email protected] nagios-4.1.1] make all
[[email protected] nagios-4.1.1] make install #安装nagios
[[email protected] nagios-4.1.1] make install-init #安装nogios的
[[email protected] nagios-4.1.1] make install-commandmode #安装命令模式 的
[[email protected] nagios-4.1.1] make install-config #安装配置文件的
[[email protected] nagios-4.1.1]# make install-webconf #会在/etc/httpd/conf.d/下生成nagios.conf
创建一个登陆nagios web 程序的用户，这个用户账号在以后通过web 登陆nagios认证时所用 ,这里的创建路径要与 /etc/httpd/conf.d/nagios.conf里面的路径相同
[[email protected] share]# htpasswd -c /etc/nagios/htpasswd.users nagiosadmin
# 安装插件
解压文件
[[email protected] src]# cd nagios-plugins-1.4.16
[[email protected] src]# ./configure --with-nagious-user=nagios --with-nagios-group=nagios
[[email protected] src]# make
[[email protected] src]# make install
[[email protected] nagios-plugins-1.4.16]# service httpd restart
[[email protected] nagios-plugins-1.4.16]# service nagios restart
<!-- 注意： nagios里面有cgi脚本，而selinux 会阻止所以要关闭selinux-->

<!-- 带register 0 就是模板-->
客户端安装插件
<!--先安装openssl-devel包-->
1)创建用户
[[email protected] src]useradd nagios
[[email protected] src]passwd nagios
2)解压插件包并进入安装插件
[[email protected] src]tar -xvf nagios-plugins-1.4.15.tar.gz
[[email protected] src] cd nagios-plugins-1.4.15
[[email protected] nagios-plugins-1.4.15]./configure --enable-redhat-pthread-workaround
[[email protected] nagios-plugins-1.4.15] make
[[email protected] nagios-plugins-1.4.15]make install
3）解压NRPE包并进入安装NRPE
[[email protected] src]# tar -xvf nrpe-2.14.tar.gz
[[email protected] src]# cd nrpe-2.14
[[email protected] src]# ./configure --with-prefix=/usr/local/nagios --enable-command-args
[[email protected] nrpe-2.14]# make all
[[email protected] nrpe-2.14]# make install-plugin ##安装check_nrpe 这个插件
[[email protected] nrpe-2.14]# make install-daemon ##安装deamon
[[email protected] nrpe-2.14]# make install-xinetd ##安装超级进程
[[email protected] nrpe-2.14]# cp /usr/src/nrpe-2.14/init-script /etc/init.d/nrpe
[[email protected] nrpe-2.14]# chmod +x /etc/init.d/nrpe
[[email protected] nrpe-2.14]# make install-daemon-config ##安装配置文件
4）修改目录权限
[[email protected] nrpe-2.14]# chown nagios:nagios /usr/local/nagios/
[[email protected] nrpe-2.14]# chown -R nagios:nagios /usr/local/nagios/libexec/
5) 编辑nrpe配置文件
[[email protected] nrpe-2.14]# vim /usr/local/nagios/etc/nrpe.cfg
allowed_hosts=127.0.0.1,172.16.9.128
##以下两步是如果把NRPE服务交给超级进程要更改的
[[email protected] nrpe-2.14]# vim /etc/services
nrpe 5666/tcp
[[email protected] nrpe-2.14]# vim /etc/xinetd.d/nrpe
only_from = 127.0.0.1 172.16.9.128
服务器安装插件
1)解压进入
[[email protected] src]# tar -xvf nrpe-2.14.tar.gz
[[email protected] src]# cd nrpe-2.14
2)安装check_nrpe 插件
[[email protected] nrpe-2.14]# ./configure
[[email protected] nrpe-2.14]# make all
[[email protected] nrpe-2.14]# make install-plugin
3) 测试
[[email protected] nrpe-2.14]# /usr/local/nagios/libexec/check_nrpe -H 172.16.9.129
