不知为何，PVE 中的 爱快 时不时会宕机，找了一个脚本，每隔一分钟检测一次虚拟机是否有心跳，如果没有心跳，就强制重启虚拟机。记录在这里。

#!/usr/bin/env bash
function check_and_restart() {
    vm_id="${1}"
    vm_ip="${2}"
    # curl --connect-timeout 5 -sSL "${vm_ip}" > /dev/null
    ping -c 1 "${vm_ip}" > /dev/null
    if [[ $? != 0 ]]; then
        now=`timedatectl status | grep 'Local time' | awk -F"Local time: " '{ print $2 }'`
        echo "[${now}] [NO] id = ${vm_id}, ip = ${vm_ip}"
        /usr/sbin/qm stop "${vm_id}"
        /usr/sbin/qm start "${vm_id}"
    fi
}

function main() {
    vm_list=${1}
    for each in ${vm_list}; do
        vm_id=`echo "${each}" | awk -F: '{ print $1 }'`
        vm_ip=`echo "${each}" | awk -F: '{ print $2 }'`
        check_and_restart "${vm_id}" "${vm_ip}"
    done
}

# 需要检查的虚拟机列表，格式为 vm_id:vm_ip
vm_list="
100:10.0.0.1
101:10.0.0.2
"

# 打印时间
# timedatectl status | grep 'Local time' | awk -F"Local time: " '{ print $2 }'

main "${vm_list}"

将以上文件保存至 /root/check_and_restart/check_and_restart.sh

添加定时任务

crontab -e

每隔一分钟检测一次

*/1 * * * * bash /root/check_and_restart/check_and_restart.sh >> /root/check_and_restart/log.txt

重启crontab服务

/etc/init.d/cron restart
