[![Hits](https://hits.spiritlhl.net/Oracle-server-keep-alive-script.svg?action=hit&title=Hits&title_bg=%23555555&count_bg=%2324dde1&edge_flat=false)](https://hits.spiritlhl.net) 4 | 5 | ## 甲骨文服务器保活脚本 6 | 7 | 适配系统：已在Ubuntu 20+，Debian 10+, Centos 7+, Oracle linux 8+，AlmaLinux 8.5+ 8 | 9 | 上述系统验证无问题，别的主流系统应该也没有问题 10 | 11 | 可选占用：CPU，内存，带宽 12 | 13 | 安装完毕后如果有问题请卸载脚本反馈问题(重复卸载也没问题) 14 | 15 | 所有资源(除了CPU)可选默认配置则动态占用，实时调整，避免服务器有别的任何资源已经超过限额了仍然再占用资源 16 | 17 | 为避免GitHub的CDN抽风加载不了新内容，所有新更新已使用[Gitlab仓库](https://gitlab.com/spiritysdx/Oracle-server-keep-alive-script) 18 | 19 | 由于speedtest-go的release依赖于GitHub，所以请检查 [www.githubstatus.com](https://www.githubstatus.com/) ,有问题时无法安装带宽占用 20 | 21 | 请留意脚本当前更新日期：2023.09.24.08.37 22 | 23 | **由于友人实测，资源占用感觉也是玄学，一个号四个服务器全部停机，但号还在，也有人一直不占用，但就是没停机的问题，所以该项目将长期保持现有状态，非必要不再更新** 24 | 25 | **也有说要在上面解析一个网址做一个网站挂着的，感觉也是玄学，自己测试吧** 26 | 27 | ### 说明 28 | 29 | 选项1安装，选项2卸载，选项3更新安装引导脚本，选项4退出脚本 30 | 31 | 安装过程中无脑回车则全部可选的占用都占用，不需要什么占用输入```n```再回车 32 | 33 | 如果选择带宽占用，会询问使用speedtest-go占用还是使用wget占用，按照提示进行选择即可 34 | 35 | 有询问是否需要带宽占用的参数自定义，这时候默认选项就是```n```，回车就使用默认配置，输入```y```再回车则需要按照提示自定义参数 36 | 37 | ``` 38 | curl -L https://gitlab.com/spiritysdx/Oracle-server-keep-alive-script/-/raw/main/oalive.sh -o oalive.sh && chmod +x oalive.sh && bash oalive.sh 39 | ``` 40 | 41 | 或 42 | 43 | ``` 44 | bash oalive.sh 45 | ``` 46 | 47 | 或 48 | 49 | ``` 50 | bash <(wget -qO- --no-check-certificate https://gitlab.com/spiritysdx/Oracle-server-keep-alive-script/-/raw/main/oalive.sh) 51 | ``` 52 | 53 | ### 特点 54 | 55 | - 提供两种CPU占用模式：DD模拟占用和科学计算模式，用户可以自由选择，占用范围设置在15%至25%之间，更推荐DD模拟占用。 56 | - DD模拟占用在守护进程中设置了CPU占用的最高限制。 57 | - 默认情况下，CPU占用设置为25%最高值，计算方法是核数乘以20%，如果计算结果低于25%，则设置为25%；如果计算结果高于25%，则按照计算结果的比例进行设置。 58 | - 内存占用设置为占用总内存的25%，占用时间为300秒，休息时间为300秒。 59 | - 每300秒检测一次内存占用情况，并根据需要动态调整占用大小。如果内存占用已经大于25%，则不增加占用。 60 | - 在占用过程中，使用守护进程和开机自启服务，以确保占用任务持续且有效。 61 | - 默认选项的带宽占用每45分钟下载一次大小在1G至10G之间的文件，只进行下载而不保存。在下载过程中会占用硬盘空间，但在下载完成后会自动释放。 62 | - 默认选项的带宽占用动态调整实际下载的带宽/速率，限制每次下载的最长时长为6分钟。在每次下载之前，会测试最大可用带宽，并根据实时结果将下载速率设置为30%的带宽。 63 | - 带宽占用测试使用了speedtest-cli和speedtest-go两种工具，以防其中之一不可用时使用第二种工具，用户可以自定义设置带宽占用，此时详见设置提示。 64 | - 提供一键卸载所有占用服务的选项，卸载将删除所有脚本、服务、任务、守护进程和开机自启设置。 65 | - 提供一键检查更新的功能，更新范围仅限于脚本更新。**请在更新后重新设置占用服务** 66 | - 对所有进程执行增加唯一性检测，避免重复运行，使用PID文件进行判断。 67 | 68 | 如若不希望一键的，希望自定义设置时间的，请查看[README_CRON.md](https://gitlab.com/spiritysdx/Oracle-server-keep-alive-script/-/blob/main/%20README_CRON.md)自行设置定时任务 69 | 70 | ###

-------------------------------------------------------------------------------- /README_CRON.md: -------------------------------------------------------------------------------- 1 | ### 自定义定时任务的命令 2 | 3 | 4 | 由于部分人需要自定义定时任务，我又懒得写定时套装，以下是和本脚本同类型占用的简短命令，怎么定时就自己搞吧，都是shell命令可以写到定时里 5 | 6 | 至于怎么定时，要么你在crontab中设置，要么在nezha监控面板设置，要么在宝塔定时任务中设置，怎么搞自己谷歌百度去吧 7 | 8 | 9 | #### CPU 10 | 11 | 下载脚本 12 | ``` 13 | curl -L https://gitlab.com/spiritysdx/Oracle-server-keep-alive-script/-/raw/main/cpu-limit.sh -o cpu-limit.sh && chmod +x cpu-limit.sh 14 | mv cpu-limit.sh /usr/local/bin/cpu-limit.sh 15 | ``` 16 | 17 | CPU占用 18 | ``` 19 | bash /usr/local/bin/cpu-limit.sh 20 | ``` 21 | 22 | CPU释放 23 | ``` 24 | kill $(ps -efA | grep cpu-limit.sh | awk '{print $2}') && kill -9 $(cat /tmp/cpu-limit.pid) && rm -rf /tmp/cpu-limit.pid 25 | ``` 26 | 27 | #### 内存 28 | 29 | 内存占用 30 | 31 | 内存以MB计算的大小，修改xxxxx为对应数目 32 | 33 | ``` 34 | mkdir /tmp/memory && mount -t tmpfs -o size=xxxxxM tmpfs /tmp/memory && dd if=/dev/zero of=/tmp/memory/block 35 | ``` 36 | 37 | 内存释放 38 | ``` 39 | rm /tmp/memory/block && umount /tmp/memory && rmdir /tmp/memory 40 | ``` 41 | 42 | 内存占用实际只有ARM有要求(如果我没理解错的话) 43 | 44 | #### 网络占用，跑完自动释放 45 | 46 | 下载脚本 47 | ``` 48 | curl -L https://gitlab.com/spiritysdx/Oracle-server-keep-alive-script/-/raw/main/bandwidth_occupier.sh -o bandwidth_occupier.sh && chmod +x bandwidth_occupier.sh 49 | mv bandwidth_occupier.sh /usr/local/bin/bandwidth_occupier.sh 50 | ``` 51 | 52 | 对应需要安装的```speedtest-cli```或```speedtest-go```自行安装 53 | 54 | 安装```speedtest-go```的记得执行```mv speedtest-go /usr/local/bin/ ``` 55 | 56 | 运行脚本(也就是你需要定时的命令) 57 | ``` 58 | bash /usr/local/bin/bandwidth_occupier.sh 59 | ``` 60 |
