Nagios是一款功能强大的网络监视工具，它可以有效的监控windows、linux、unix主机状态以及路由器交换机的网络设置，打印机工作状态等，并将状态出现异常的服务及时以邮件、msn短信等形式第一时间通告管理员。由于它是一款遵循GPLv2的开源网络监控软件，以其出色的性能低廉的使用成本，深受广大用户的好评。

cd nagios-plugins-1.4.15 ./configure --with-nagios-user=nagios --with-nagios-group=nagios --with-mysql #添加mysql依赖 make && make install #编译并安装 Ps：作者在安装nagios-cn-3.2.3.tar过程中，在此处编译完成发现mysql关联库文件本跳过。经分析原因是由于在编译nagios时修改了nagios的默认安装路径（非/usr/local/nagios）。 解决办法： |
|
cp /usr/lib/mysql/mysql_config /usr/lib/pkgconfig/
#将mysql的配置文件放在这个目录下使之能够在编译过程中读到相关配置选项 再进行编译安装nagios-plugins |
|
chkconfig --add nagios
chkconfig nagios on #添加nagios到开机启动项 vim /etc/profile PATH=$PATH:/usr/local/nagios/bin #向profile加入这一行，指明nagios命令的path . /etc/profile nagios -v /usr/local/nagios/etc/nagios.cfg #检查配置文件的语法 service nagios start #如语法监测为报错则尝试开启服务 |
|
方法一、直接关闭selinux
getenforce #查看selinux的运行状态 setenforce 0 #如果是enforce（开启）状态，则关闭 Ps：如果您想在今后的使用中完全关闭selinux，可以通过编辑/etc/sysconfig/selinux文件，将其中的selinux后面的值“force”修改为“disable”即可。 方法二、修改相关文件的type chcon -R -t httpd_sys_content_t /usr/local/nagios/sbin chcon -R -t httpd_sys_content_t /usr/local/nagios/share #进行这些操作就可以在selinux开启的状态下正常访问nagios |
