Cobra_Fast's questions

我的托管服务提供商向我提供了以下信息：

子网：2a02:f99:0:64::/64
网关：2a02:f99:0:64::1

所以我做了（是eth3的，是正确的界面）

ip addr add 2a02:f99:0:64::2/64 dev eth3
ip -6 route add ::/0 via 2a02:f99:0:64::1 dev eth3

但

$ ip -6 neigh show
2a02:f99:0:64::1 dev eth3 FAILED
$ ping6 google.com
PING google.com(ams16s30-in-x0e.1e100.net) 56 data bytes
From 2a02:f99:0:64::2 icmp_seq=1 Destination unreachable: Address unreachable
...

我也试过

ip -6 route del ::/0 via 2a02:f99:0:64::1 dev eth3
ip -6 route add ::/0 via fe80::1 dev eth3

但这并没有改变任何东西，仍然无法进入或退出。

我哪里做错了？如何让 IPv6 运行？

2017-07-07 更新：

托管服务提供商坚称基础设施很好。

可以访问同一子网的另一台机器可以绑定地址并通过我认为的路由器广告 (RA) 建立 IPv6 连接，因为仅fe80::20a:8bff:fe98:3400作为网关工作而提供商指定的网关地址不工作。

然而，这篇文章所涉及的机器仍然无法找到任何邻居。启用 RA 似乎也没有任何效果。

在两台机器的交叉连接（在它们的辅助 NIC 上）运行 IPv6 可以立即工作，因此 IPv6 基本上应该对它们都可用（所有粘贴都来自有问题的机器）：

PING fe80::62eb:69ff:fed2:a122%eth2(fe80::62eb:69ff:fed2:a122) 56 data bytes

IP 配置如下所示：

邻居发现只找到接口的链路本地地址：

PING ff02::1%eth3(ff02::1) 56 data bytes

--- ff02::1%eth3 ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 1998ms

尝试 ping 网关也会导致：

2017-07-07 #2 更新：

提供商说两台机器都挂在同一个交换机上。这意味着这必须是一个配置问题。

2017-07-08 更新：

我已将内核从 3.4 升级到 3.16，并将 Intel igbNIC 驱动程序升级到他们网站上的最新软件包。然而，无济于事，观察到的行为根本没有改变。

我已经定义了以下配置文件

#include <tunables/global>

/usr/bin/convert.im6 {
  #include <abstractions/base>

  /usr/bin/convert.im6 mr,

  /** mrwlkix,
  set rlimit as <= 8G,
}

并通过aa-enforce /usr/bin/convert.
但是，这个二进制文件的新启动进程根本不会出现aa-status。

可能是因为它们是从 开始的nice -n +19 convert ...吗？
或者是因为另一个具有已定义配置文件的进程正在启动它们？

出了什么问题？如何让 AppArmor 强制执行这些流程？

好的，我已经将 5.1 版更新到 5.6 版，没有使用update-alternatives. 这在我们的生产/主服务器上工作得很好，但是我们的复制从服务器似乎有问题。

首先，在进程列表中mysqld_safe只是logger无限期地启动该工具，直到数百个实例正在运行并且我手动重新启动服务器。
其次，服务器一次只运行几秒钟而没有真正重新启动。每当我status在 MySQL shell 中运行时，它必须重新连接，并且状态打印会显示类似Uptime: 9 sec的内容，即使它已经运行了几个小时。

输出SHOW FULL PROCESSLIST：

系统日志看起来不错，除了它抱怨performance_schema数据库中的每个表，如下所示：

[ERROR] Native table 'performance_schema'.'session_account_connect_attrs' has the wrong structure

出了什么问题，我该如何解决？

我正在使用 Froxlor 运行 Apache2，因此每个客户都有自己的访问权限和错误登录/var/customers/logs。

现在，是否有可能在保留此功能的同时还具有全局访问权限和/var/log包含所有流量和错误的良好旧方法的错误日志？

我试过CustomLog在全球范围apache2.conf内定义 a 无济于事。

所以，我的问题是我无法让 IPv6 正常工作。例如，Ping6 只是connect: Network is unreachable在我尝试 ping 时告诉我ipv6.google.com。

ifconfig看起来像（有点审查）：

另一个奇怪的事情是，只有当我告诉ping6专门使用eth0接口时，ping 我自己的 IPv6 地址才有效，-I eth0否则会返回unknown host。

我读过的一件事是我需要以某种方式在路由表中指定我的路由器，但我什至不知道路由器的地址而且我也不知道如何找到它（因为我一点也不像网络专家和 IPv6 对我来说似乎比 IPv4 更令人困惑）。

任何想法或解决方案？

当我注意到我在我的 Debian6 服务器上 /etc/cron.weekly 中放置的备份脚本没有被执行时，我将这个小脚本放入其中，以查看每周的 cronjob 是否被执行：

#!/bin/bash
echo 'CRON RAN' > /var/log/cron-weekly-runcheck.log

保存为

-rwxr-xr-x 1 root root 64 Jul 15 02:14 /etc/cron.weekly/runcheck.sh

当我今天检查时，它应该创建的日志文件不存在。
crontab 如下所示（据我所知应该是默认的 debian6 crontab）：

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

# m h dom mon dow user  command
17 *    * * *   root    cd / && run-parts --report /etc/cron.hourly
25 6    * * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )
47 6    * * 1   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly )
52 6    1 * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly )

在任何日志文件中显示的每周 cronjob 的所有内容都是这一行：

Jul 16 06:47:01 wtwrp /USR/SBIN/CRON[29272]: (root) CMD (test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly ))

旁注：cron.daily自从 logrotate 起作用以来似乎起作用了。cron.hourly里面没有脚本。

关于可能出错的任何想法？
