因为perl-fcgi进程意外中断，但是进程未退出变成了孤儿进程，所以就变成这样了

修改下脚本start_perl_cgi.sh

[[email protected] nginx]# ./start_perl_cgi.sh start

基于Nginx平台安装Nagios监控系统的相关文章

Cacti+Nagios监控系统（五）：Nagios监控windows（基于check_nt）

一.工作原理 Nagios服务器使用check_nt工具与客户端程序通讯,客户端程序NSCP使用命令来获取本地客户端的信息并返回给check_nt. check_nt只是NSCP其中一项服务,Nagios还可以通过check命令(如check_http检查WEB服务).check_nrpe.NSCA.WMI来监控windows客户端. 二.下载客户端程序 下载地址:  http://nsclient.org/nscp/downloads 64位系统下载:NSCP-0.4.1.105-x64.ms

Cacti+Nagios监控系统（二）：安装Cacti

一.设置mysql,创建Cacti数据库和账号 mysql -u root -p mysql> create database cactidb; mysql> GRANT ALL ON cactidb.* TO [email protected] IDENTIFIED BY '123456'; mysql> flush privileges; mysql> quit 二.安装rrdtool yum -y install rrdtool  rrdtool-devel  rrdtool

Cacti+Nagios监控系统（三）：安装Nagios

一.添加用户 groupadd nagcmd useradd -G nagcmd nagios passwd nagios 123456 usermod -a -G nagcmd apache 二.安装nagios cd /root/download wget http://jaist.dl.sourceforge.net/project/nagios/nagios-4.x/nagios-4.0.7/nagios-4.0.7.tar.gz 也可以从这里下载:http://www.nagios.o
