服务器服务监测脚本（更新）

上一回发布了服务器监控脚本，这是该脚本的新版。此次更新内容包括：

1、添加了PATH处理，防止crontab执行脚本失败
2、精简了部分变量
3、添加了NRPE进程的监控

有参考上一版本脚本的朋友如有需要，可参照更新一下。

脚本内容如下：

#!/bin/bash
#    service --> name to test
#    apache --> apache|apache2|http|httpd
#    nginx --> nginx
#    mysql --> mysql|mysqld
#    php-cgi --> php-cgi
#    vsftpd --> vsftp|vsftpd
#    pure-ftpd --> pure-ftp|pure-ftpd
#    apache-tomcat --> java
#    nrpe --> nrpe
# Set the service name you want to test and its max number of processes first.
# Don't forget to check the bin path for each service.
