服务器无故重启可能与 acpi有关系

2012年6月20日 eric 发表评论 阅读评论

一影院反应linux服务器总有时候自己重启,发生故障有2-3天了。接到反应之后 登录到服务器 开始排查 主板温度 CPU 温度 内存利用 等等都很正常。开始检查日志。

检查 last

server $> last

正常重启的 会有 down 字样,无故重启的没有。

然后检查 message 日志,发现问题
serve $> vim /var/log/message

发现 问题,acpi 与内核可能有不兼容的问题· 我是 服务器 ,不是笔记本,所以我可以直接在启动的时候 off 干掉。

注意这里 可不能加 acpi=off 因为我们服务器都是多核多线程的CPU,所以我们要加入 acpi=ht
详情:http://wiki.ubuntu.org.cn/UbuntuHelp:BootOptions/zh#.E5.8F.82.E6.95.B0:_acpi.3Dht

修改 grub.conf

保存退出,问题解决了,目前影院反映服务器正常了。日志里的错误也消失了。
