　　8月3日，我写了“Linux服务器监控系统 ServMon V1.0”，今天，ServMon V1.1 版本亮相。

　　ServMon的原理是用shell脚本定时抓取被监控Linux服务器上的信息，再用curl POST到监控机的PHP接口程序上，由PHP接口程序对信息进行分析，如果存在异常，则发送报警邮件给管理员。报警邮件演示页面请见：http://blog.zyan.cc/read.php/276.htm

　　

　　ServMon V1.1 在 1.0 的基础上，增加了对Linux系统负载的监控，并编写了客户端自动安装包：

　　1、被监控端服务器（Linux）
　　(1)、下载并安装ServMon Client

引用

wget http://blog.zyan.cc/soft/linux/servmon/servmon-1.1.linux.tar.gz
tar zxvf servmon-1.1.linux.tar.gz
cd servmon-1.1
./install -i http://yourdomain/servmon/interface.php password

　　注：此处的password为interface.php程序中设置的数据传输验证密码。

　　客户端安装包源码：
　　│
　　├─install
　　├─[src]
　　│　 ├─[bin]
　　│　 │　　├─diskstat_send
　　│　 │　　├─loadstat_send
　　│　 │　　└─swapstat_send
　　│　 ├─[cron]
　　│　 │　　└─servmon
　　│　 └─[data]

　　屏幕演示：
　　

　　2、监控端服务器配置（Linux）
　　(1)、启动sendmail
　　/usr/sbin/sendmail -bd -q30m
　　-b：指定Sendmail在后台运行，并且监听端口25的请求。
　　-d：指定Sendmail以Daemon方式运行（守护进程）。
　　-q：当Sendmail无法将邮件成功地发送到目的地时，它会将邮件保存在队列里。该参数指定邮件在队列里保存的时间。其中的30m表示保留30分钟。

　　(2)、修改php.ini的[mail function]部分为以下内容，然后重启Apache，使PHP能够使用mail()函数发送电子邮件

引用

[mail function]
; For Win32 only.
;SMTP = localhost
;smtp_port = 25

; For Win32 only.
;sendmail_from = me@example.com

; For Unix only. You may supply arguments as well (default: "sendmail -t -i").
sendmail_path = /usr/sbin/sendmail -t -i

　　(4)、在MySQL上创建一个数据库servmon，然后在该数据库中执行以下SQL语句创建表：

引用

CREATE TABLE `tb_diskstat` (
`ip` varchar(128) NOT NULL default '',
`date` int(10) NOT NULL default '0',
UNIQUE KEY `ip` (`ip`)
) TYPE=MyISAM;

　　备注：这张表是PHP接口程序用来记录发送磁盘分区报警邮件的时间，避免在一段时间内重复发送大量报警邮件的。

　　(3)、PHP接口程序
　　http://yourdomain/servmon/interface.php
