cpulimit

因为贫穷, 所以买的特价 vps 各种限制

跑 hexo g, cpu 100% 都会被停机

所以只能靠 限制 cpu 来解决
本来想通过 cgroup 来限制，发现比较麻烦

后寻到 cpulimit

yum install epel-release cpulimit

cpulimit -h
Usage: cpulimit [OPTIONS...] TARGET
   OPTIONS
      -l, --limit=N          percentage of cpu allowed from 0 to 100 (required)//cpu限制的百分比
      -v, --verbose          show control statistics//显示版本号
      -z, --lazy             exit if there is no target process, or if it dies//如果限制的进程不存在了，则退出。
      -i, --include-children limit also the children processes//包括子进程。
      -h, --help             display this help and exit //帮助，显示参数
   TARGET must be exactly one of these:
      -p, --pid=N            pid of the process (implies -z) //进程的pid
      -e, --exe=FILE         name of the executable program file or path name //可执行程序
      COMMAND [ARGS]         run this command and limit it (implies -z)

nohub cpulimit -e hexo -l 50 -i > /tmp/cpulimit.log 2>&1 &
