当你要监视一台Linux机器时,你会有很多的选择。虽然现在有很多产品质量监控方案(比如 Nagios、 Zabbix、 Zenoss),它们拥有华丽的UI,可扩展监控,易于理解的报告等等,这些方案对于大多数终端用户都太过于强大了。如果你只需检查Linux服务器或桌面的基本状态(比如,CPU负载、内存使用、活跃进程),就请考虑一下[linux-dash][1]。

linux-dash是一款面向Linux机器的基于web的轻量级监控面板,可以实时显示不同的系统属性,比如CPU负载、内存使用、磁盘使用、网络速度、网络连接、上下行带宽、登录用户、运行中的进程等等。linux-dash没有后端数据库库来存储长期统计。在任何已有的web服务器(如Apache、Nginx)上运行linux-dash,你就可以用了。这是一个快速又简单的方法来对个人项目进行远程监控。

在这篇教程中,我会描述**如何在Linux的Nginx web服务器上设置linux-dash**。这里用Nginx,而不是Apache,是因为它更轻量。

### 在Debian、Ubuntu或者Linux Mint上设置linux-dash ###
|
2014-04-16 17:38:22 +08:00
|
|
|
|
|
2014-04-18 14:34:45 +08:00
|
|
|
|
首先,安装带php-fpm的Nginx web服务器。
|
2014-04-16 17:38:22 +08:00
|
|
|
|
|
|
|
|
|
$ sudo apt-get install git nginx php5-json php5-fpm php5-curl
|
|
|
|
|
|
2014-04-18 14:34:45 +08:00
|
|
|
|
为linux-dash创建如下Nginx配置文件/etc/nginx/conf.d/linuxdash.conf。 本例中,我们使用8080端口。
|
2014-04-16 17:38:22 +08:00
|
|
|
|
|
|
|
|
|
$ sudo vi /etc/nginx/conf.d/linuxdash.conf
|
|
|
|
|

|
|
|
|
|
2014-04-18 14:34:45 +08:00

|
|
|
|
|
2014-04-18 14:34:45 +08:00
|
|
|
|
安装Nginx与php-fpm组件。
|
2014-04-16 17:38:22 +08:00
|
|
|
|
|
|
|
|
|
$ sudo yum install git nginx php-common php-fpm

|
|
为linux-dash程序配置Nginx,如下创建/etc/nginx/conf.d/linuxdash.conf
|
2014-04-16 17:38:22 +08:00
|
|
|
|
|
|
|

|
}
|
|
|
|
|
|
2014-05-15 19:38:22 +08:00
|
|
|
|
接下来,编辑`/etc/php-fpm.d/www.conf`来配置php-fpm。在这个文件中,确保按如下编辑"user", "group" 和 "listen"字段。你可以不改变剩下的配置。
|
2014-04-16 17:38:22 +08:00
|
|
|
|
|
|
|
|
|
$ sudo vi /etc/php-fpm.d/www.conf
|
|
|
|
|
|
2014-05-15 19:38:22 +08:00
|
|
|
|
listen = /var/run/php-fpm.sock
|
|
|
|
|
user = nginx
|
|
|
|
|
group = nginx
|
|
|
|
|
|
2014-04-16 17:38:22 +08:00
|
|
|
|
|
2014-04-18 14:34:45 +08:00
|
|
|
|
在/var/wwwx下载并安装linux-dash。
|
2014-04-16 17:38:22 +08:00
|
|
|
|
|
|
|
|
|
$ git clone https://github.com/afaqurk/linux-dash.git
|
|
|
|
|
$ sudo cp -r linux-dash/ /var/www/
|
|
|
|
|
$ sudo chown -R nginx:nginx /var/www
|
|
|
|
|
|
2014-04-18 14:34:45 +08:00
|
|
|
|
最后,重启Nginx和php-fpm,并设置开机自启。
|
2014-04-16 17:38:22 +08:00
|
|
|
|
|
|
|
|
|
$ sudo service php-fpm restart
|
|
|
|
|
$ sudo service nginx restart
|
|
|
|
|
$ sudo chkconfig nginx on
|
|
|
|
|
$ sudo chkconfig php-fpm on
|
|
|
|
|
|
2014-04-18 14:34:45 +08:00
|
|
|
|
在本例中,我们已经配置linux-dash使用TCP端口8080。所以确保防火墙没有阻止TCP 8080端口。

下面是linux-dash的截图。web面板包含了几个小部件,每个都会显示特性的系统参数。你可以通过重安排并且/或者关闭一些小部件来自定义web面板的外观。[这里][3]是一个linux-dash创建者的演示站点。
