今晚遇到的奇葩事情也是多。刚才在Vultr的两台VPS之间正通过private network传输数据呢
突然后悬挂(大雾)就断了,然后就再也ping不通对方了。
ifup,ifconfig eth1 up都试了也没有用。就差报警了。
这时机智的我去Support发了一个ticket。
没想到不到两分钟客服就回了
Hello,
This is a known issue. We have implemented updates to our network
infrastructure and would like to refresh your existing instance(s) to
resolve the underlying issue. This will require us to restart your
instance so just let us know when we can do this for you.PLEASE NOTE: You may not perform this restart yourself; we must
perform this for you and the restart window should be less than five
minutes in length for any given instance.Jeff Benfer Systems Administrator
卧槽,基础设施历史遗留问题,要重启。还不能自己来。这么坑。
好吧看来只能重启了。进服务器收拾收拾东西,发了个
Ok,you can restart it now,I’ve stopped the important services.
又是不到两分钟,服务器重启好了0.0 卧槽速度好快。完全没有感觉,检查了一下确实是重启了。
这时发现,private network还是不能用啊,ifconfig了一下。没有eth1。 ifup eth1 报错
Device eth1 does not seem to be present, delaying initialization.
哎哟卧槽看这情况是给我换了个虚拟网卡啊。
赶紧cat /etc/udev/rules.d/70-persistent-net.rules一发压压惊
# PCI device 0x1af4:0x1000 (virtio-pci)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="不给看", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
# PCI device 0x1af4:0x1000 (virtio-pci)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="不给看", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x1af4:0x1000 (virtio-pci)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="不给看", ATTR{type}=="1", KERNEL=="eth*", NAME="eth2"
eth1和2都有是什么鬼,又发ticket问一下小哥,三分钟后小哥回复了
Hello,
eth2 should work for you. Please let us know if it does not.

那就把eth1的配置转移到eth2上试试吧。ifup eth2.顺利完成,互相ping了一下对面,终于通了。泪流满面
赶紧把必要的服务开启了一下,docker该开的也都开好了,MYSQL的主从同步检查了一下,还是连不上master啊
然而突然想到iptables的配置里写的3306端口只开放给eth1。赶紧去改了又show slave status\G一下。终于OK了。
然而说了这么多,除了分享网络配置和这RP不好遇到的奇葩问题以外,严重赞一下Vultr的ticket客服,凌晨两三点能在两分钟左右就回复我的ticket简直是业界良心,还能迅速解答我的问题。相比之下Digitalocean的10-20分钟略慢。国内的服务商就更不用说了。动辄一两天慢得要死不说,搞来搞去完全不专业。
最后的最后,放一下Vultr和Do的带Aff链接,虽然没人会用
