服务器保活脚本/状态监控脚本,自动占用CPU内存/获取状态上报

适用于debian/ubuntu

功能:

自动占用CPU和内存(不会爆机)

自动ping测试

自动上报日志(流量消耗太少,达不到保活要求)

脚本会自动下载所需要的软件包

其中几个参数需要设置

用来测试ping的地址列表,一个txt文件,文件内每行一个网址

URL_LIST_URL="https://地址/urls.txt"

状态上报URL,POST方式上传一个JSON,不需要上报就随便填个地址即可

UPLOAD_URL="https://地址/Upload"

运行持续时间,默认120小时

MAX_RUNTIME=$((120 * 3600))

将整段脚本保存为一个.sh文件后上传到服务器,授予执行权限后执行一次即可.

最终生成的服务名称为: server-stability-test

文件在/etc/systemd/system/server-stability-text.service
