在这个Dockerfile中运行

mysqld时(在我的

Linux机器上,

Linux 12.04)

Dockerfile：

FROM ubuntu:precise

RUN apt-get update

RUN apt-get install -y mysql-server

CMD ["/usr/sbin/mysqld"]

我在加载共享库时遇到mysqld：error：libz.so.1：无法打开共享对象文件：权限被拒绝

而通过boot2docker在我的Mac上运行mysqld启动就好了.

我尝试了不同的基础docker图像：

> phusion / baseimage：0.9.8

> phusion / baseimage：0.9.1

> ubuntu：最新

我在主机系统上运行了apt-get update和apt-get upgrade(包括更新Mysql),我已经重新启动了主机系统.

关于如何进行的任何想法？

回答leeduhem关于libz.so.1权限的评论：

$ls -l /lib/x86_64-Linux-gnu/libz.so.1

lrwxrwxrwx 1 root root 15 Nov 10 2011 /lib/x86_64-Linux-gnu/libz.so.1 -> libz.so.1.2.3.4

$ls -l /lib/x86_64-Linux-gnu/libz.so.1.2.3.4

-rw-r--r-- 1 root root 92720 Nov 10 2011 /lib/x86_64-Linux-gnu/libz.so.1.2.3.4

使用更改权限

$chmod +x /lib/x86_64-Linux-gnu/libz.so.1.2.3.4

我仍然得到错误.

运行strace -o /tmp/mysql.strace mysqld和cat /tmp/mysql.strace给出

查看跟踪似乎指示的目录/ lib和/ lib / x86_64-Linux-gnu是不允许的：

$ls -ld /lib

$ls -ld /lib/x86_64-Linux-gnu

drwxr-xr-x 3 root root 4096 Mar 17 13:39 /lib/x86_64-Linux-gnu

删除容器为我解决了这个问题.

更新：该解决方案的工作时间不长.

所以我一直在搜索,找到了something related with Apparmor.

如果您在主机上安装了mysql,Apparmor可能会限制对Docker容器上安装的mysql访问此共享库.以下修复了问题：

#Type this on your host terminal

sudo ln -s /etc/apparmor.d/usr.sbin.mysqld /etc/apparmor.d/disable/

sudo apparmor_parser -R /etc/apparmor.d/usr.sbin.mysqld
