卸载腾讯云轻量机型内置的监控程序 简单介绍腾讯云在服务器内置了多套安全监控程序，如果您不需要可以卸载掉。卸载云服务器监控组件 /usr/local/qcloud/stargate/admin/uninstall.sh /usr/local/qcloud/monitor/barad/admin/uninstall.sh卸载云镜/usr/local/qcloud/YunJing/uninst.sh卸载TAT自动化助手systemctl stop tat_agent systemctl disable tat_agent rm -f /etc/systemd/system/tat_agent.service【谨慎可选】卸载其他服务腾讯云除了上述服务外，在/usr/local/qcloud目录下还有其他的一些服务。谨慎可选rm -fr /usr/local/qcloud 检查 agent 进程是否还在ps -A | grep agent -
Linux服务器出入口网络带宽速率计算Shell脚本 概述用于计算服务器出入口带宽实际速率，方便统计服务器网络信息。脚本功能该脚本会根据当前服务器内存剩余空间判断生成约为1.5G临时文件，并提交至指定的url地址进行出口带宽占用。通过检查默认出入口网卡流量数值来判断出入口带宽网络速率。执行效果脚本内容#!/bin/bash # 服务器出入口网络带宽速率计算 # Author: admin@ym68.cc # Date: 2022-05-06 # Version: 0.0.3 # Description: 该脚本用于计算服务器外网出入口网络带宽速率 set +m # 检查是否有测速请求进程未完成 ps -o pid,command|awk '/Speed_Test_File[[:space:]]/ {print $1}'|xargs -i kill {} 2> /dev/null # 默认流量出口网卡 Default_Network_Device_Name=`route -n|awk '/^0.0.0.0/ {print $8}' |uniq` # 临时测速文件 Temp_Speed_File="/dev/shm/Speed_Test_File" if [ ! -f "${Temp_Speed_File}" ];then # 剩余内存计算 Free_Mem_Info=`awk -F":[[:space:]]" '/^MemFree:/ {print $2}' /proc/meminfo |awk '{printf "%.0F",$1/1024}'` if [ "${Free_Mem_Info}" -gt 2048 ];then Temp_Speed_Size='2000000' else Temp_Speed_Size='1563000' fi echo "开始生成 $((${Temp_Speed_Size}/1024))M 的临时文件：${Temp_Speed_File}" # 生成临时测速文件 dd if=/dev/zero of=${Temp_Speed_File} bs=1024 count=${Temp_Speed_Size} &> /dev/null fi Network_Device_Speed=`route -n|awk '/^0.0.0.0/{print $8}'|uniq |xargs -i ethtool {} 2>/dev/null|awk '/Speed/ {print $2}'` if [ "${Network_Device_Speed}" = '100Mb/s' ];then Network_Conf_Speed='2' elif [ "${Network_Device_Speed}" = '1000Mb/s' ];then Network_Conf_Speed='10' elif [ "${Network_Device_Speed}" = '10000Mb/s' ];then Network_Conf_Speed='20' elif [ "${Network_Device_Speed}" = '25000Mb/s' ];then Network_Conf_Speed='20' else Network_Device_Speed='100Mb/s(虚拟机)' Network_Conf_Speed='2' fi Down_Speed_Url_List=('https://www.baidu.com/speed' 'https://www.aliyun.com/speed' 'https://ecloud.10086.cn/speed' 'https://www.ctyun.cn/speed' 'https://cucc.wocloud.cn/speed' 'https://lol.qq.com/speed' 'https://daoju.qq.com/speed' 'https://pay.qq.com/speed' 'https://www.migu.cn/speed') for num in $(seq 1 "${Network_Conf_Speed}");do for Down_Speed_Url in ${Down_Speed_Url_List[@]};do (curl -s --interface "${Default_Network_Device_Name}" -F "data=@${Temp_Speed_File}" "${Down_Speed_Url}" &> /dev/null &) done & done & sleep 4 echo "当前默认网卡 ${Default_Network_Device_Name} 上行测速将开始，等待10s..." # 历史出口流量 Old_Network_Outlet_Flow_Sum=`awk '{print $1}' /sys/class/net/${Default_Network_Device_Name}/statistics/tx_bytes` sleep 10 # 最新新出口流量 New_Network_Outlet_Flow_Sum=`awk '{print $1}' /sys/class/net/${Default_Network_Device_Name}/statistics/tx_bytes` # 网卡出口流量字节速率 Network_Outlet_Flow_Sum=`echo |awk "{printf \"%f\", (${New_Network_Outlet_Flow_Sum}-${Old_Network_Outlet_Flow_Sum})/10}"` # 网卡出口流量比特速率 Network_Outlet_Flow_Sum_D=`echo |awk "{printf \"%f\",(${New_Network_Outlet_Flow_Sum}-${Old_Network_Outlet_Flow_Sum})*8/10}"` # 标准出口比特速率 Network_Outlet_Device_Flow_Sum_D=`echo|awk "{printf \"%f\",${Network_Outlet_Flow_Sum_D/.*}/1024/1024}"` # 标准出口字节速率 Network_Outlet_Device_Flow_Sum=`echo|awk "{printf \"%.2f\",${Network_Outlet_Flow_Sum/.*}/1024/1024}"` # 标准网络速率 Network_Outlet_Device_Flow_Type="Mbps" # 标准硬盘速率 Network_Outlet_Device_Flow_Type_D="MB" # 清理未完成进程 ps -o pid,command|awk '/Speed_Test_File[[:space:]]/ {print $1}'|xargs -i kill -9 {} 2> /dev/null if [ -z "${1}" ];then rm -f "${Temp_Speed_File}" fi # 下载速率 for num in $(seq 1 "${Network_Conf_Speed}");do (wget -q --no-check-certificate -O /dev/null -U 'Speed_Test_Query' 'https://www.ym68.cc/api/Analysis_Storage/Down.php?path=7a84YVaQOkWWEes1SJO%2BW%2Bvsvrbis7QAd3kJbCgRjHPPR1rExqyeP5zUz1jhIbnOBNaV%2FQ68BBRSNNTR%2BV9vTezkGPFzT%2ByYL4cDA%2BIuEZ%2B8NieBZ1ShGjmUS5llevf0K8kE0BeFQpv3fGYxK8%2FimGYmEM37H8sM5q3mJEPZugEn93SktYHHO8OGyJ%2FP4l9TLMGnLFzMd52nFX%2FZz2BNuRP45wJ6Pefkt5Oa4PPXbeXmo5DviLbkX%2B4I5cg0P%2Fnzgwoe69SS5QveDXVLtSNkfSNJ9BnVX2oN2DZ4hlr0XogNqbtZjFc' &> /dev/null &) (wget -q --no-check-certificate -O /dev/null -U 'Speed_Test_Query' 'https://www.ym68.cc/api/Analysis_Storage/Down.php?path=89ddFo%2ByNPB7JzVq%2BALyBaFd%2BaClbHBk8aoO%2Fcbt09YkE1M%2Bug8V2FZYAUVNeIuZQtLnMCMyz4dNsCTcCjCQy%2F8FcG%2Bxvoz2N2JYJ42zAJMCEm%2FnUEbgSgNaHSoKXrdhxv4zR85CEicwK5ADgOfIe6MBJF4EVZWRslbjJvgxGwfBh5dSQ41fv9h%2FXv8cYgFK9myNwWv0jq3Pic5od3dg384utImKSZc54zTsngZndPiJ25p12oLJPEOQbYceQFWYsT82xD2ofa9QRKA0NDlLSc1cORn%2Bw2NJmm6uhTjKv4%2BfwgftpUQ' &> /dev/null &) done & sleep 4 echo "当前默认网卡 ${Default_Network_Device_Name} 下行测速将开始，等待10s..."
