mysql 也装不上的 vps 还是第一次遇见
各位 V 友有碰到类似的问题吗？如何解决的？

之前怀疑是依赖的包太老了，顺手也看了下内核模块，加强了怀疑。
以前是做虚拟化的（ KVM/XEN ），还第一次听说 OVZ ，孤陋寡闻了吗。。
详细日志如下：

SO/SU 都没解决以上的问题。

搞定。
apt-get install perl-base=5.18.2-2ubuntu1
把 perl-base 重新安装了之后就好了，是因为中间几个包写死了 perlapi 的版本依赖，太坑爹了

主要是参考了一篇 SU 的问题，使用 apt-cache show <pkg> 看了几个包的 provide/require 确定了问题。
SU 问题： http://superuser.com/questions/797329/apt-get-wants-to-autoremove-core-packages

最后，心得，作为一个以前把项目代码编译二进制封 SO 打 RPM 制 ISO 都一天内搞定的具有强大受虐能力的码农，我表示这种问题也太 TM 坑爹了，不是一个很熟悉这套系统的人就会浪费数以小时计的时间在这种细枝末节的问题上。

anyway ，其实也只是为了一个香港的便宜 VPS ，自作孽。。

OVZ 的机器肯定是这样的啊

ovz 的只能到这个版本

想自己升内核版本还是上全虚拟化吧
不过 mysql 装不上是第一次听说，包管理器直接安也不行？

Ovz 内核没见过 3 开头的

wbsdty331

2016-01-30 20:35:23 +08:00

因为 OpenVZ 官方就只提供了 2.6.32 的，没有更高的

DesignerSkyline

2016-01-30 20:45:48 +08:00

对的， OVZ 的内核基本都停留在 2.6 ，版瓦工也这样，还是挺正常的

2016-01-30 21:00:59 +08:00

你要说 docker 不能用我还可以理解， MySQL 装不上和 2.6 内核有什么关系

vboar

2016-01-30 21:42:20 +08:00

是不是 dependency 的问题？我之前也装不了，然后 apt-get install bsdutils 就 ok 了

之前我用的是搬瓦工的 64m 内存的 vps ， mysql 死活安装不了，后来网上找了半天发现有人说 openvz 的 vps 内存要 512M 才可以正常安装 mysql ，今天升级了一下 vps ，内存变成了 512 之后成功安装，只能说搬瓦工下面小内存低端 vps 无法安装 mysql ，至于到底多少 M 内存才能安装我就不知道了。

@acrisliu
@wbsdty331 https://openvz.org/Download/kernel 其实已经到 3.10 了，不过还在 Testing 。

@vboar 是 dependency 的问题，但这个命令没有解决

ovear

2016-01-31 00:37:37 +08:00

debian 系出事三部曲 lz 试过没
apt-get clean
apt-get update
apt-get -f install

另外确定下 release 版和 apt 源

alexapollo

2016-01-31 00:41:22 +08:00

@ovear 非常怀疑是 apt 源的问题， release 是 14.04 ，不知道具体版本名在哪看
apt 源是：

deb http://archive.ubuntu.com/ubuntu trusty main restricted universe
deb http://archive.ubuntu.com/ubuntu trusty-updates main restricted universe
deb http://security.ubuntu.com/ubuntu trusty-security main restricted universe multiverse
deb http://archive.canonical.com/ubuntu trusty partner

看起来不是 OVZ 专有的源，有点怀疑是这个的问题

alexapollo

2016-01-31 00:41:46 +08:00

@ovear 三部曲有的，确定是最新的了。

xseven007

2016-01-31 00:42:21 +08:00

13 楼正解。顺便再不行就 rm -rf /var/cache/apt
应该就正常了。

alexapollo

2016-01-31 00:50:48 +08:00

@xseven007 rm 了，也重新更新了，-f 也有带，但仍然是依赖的问题。一个完整的尝试是这样的：

alexapollo

2016-01-31 00:51:14 +08:00

@xseven007 最后显示 E: Package 'perlapi-5.18.1' has no installation candidate 这个应该是解谜关键。。

2016-01-31 00:52:19 +08:00

@alexapollo 还是一个错么 0 0
lsb_release -a 可以看版本信息
Distributor ID: Ubuntu
Description: Ubuntu 14.04.3 LTS
Release: 14.04
Codename: trusty

codename 就是版本号

源的 deb http://archive.ubuntu.com/ubuntu trusty
第三个参数就是版本号， lz 不是 15 。 04 的嘛？

另外 lz 顺手查查 cache 吧
apt-cache madison perl-base
返回结果看看是哪里的

ovear

2016-01-31 00:54:20 +08:00

)顺便 libdbi-perl 和 mysql-server 也查查我觉得是源被污染了

@edsgerlin 不知道要 testing 到什么时候。。。

alexapollo

2016-01-31 01:02:27 +08:00

@ovear 搞定。
apt-get install perl-base=5.18.2-2ubuntu1
把 perl-base 重新安装了之后就好了，是因为中间几个包写死了 perlapi 的版本依赖，太坑爹了

2016-01-31 01:05:59 +08:00

@alexapollo 搞定就好-0-
我一般都不怎么带版本的 hhh
