Question

我有一个带有mysql的Docker容器。这是我的Dockerfile

FROM ubuntu:latest
USER root
RUN apt-get update
#RUN apt-get -y install default-jre
RUN apt-get install -y python-pip python-dev build-essential
RUN apt-get install -y libmysqlclient-dev
RUN apt-get install -y python-mysqldb
RUN apt-get update && \
    apt-get upgrade -y && \
    apt-get install -y git
ENV JAVA_HOME /usr/lib/jvm/java-8-openjdk-amd64

# install packages
RUN \
  apt-get update && apt-get install -y \
  ssh \
  rsync \
  vim \
  openjdk-8-jdk

# create ssh keys
RUN \
  ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa && \
  cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys && \
  chmod 0600 ~/.ssh/authorized_keys

#RUN apt-get install -y mysql-server
RUN DEBIAN_FRONTEND=noninteractive apt install -y mysql-client
RUN DEBIAN_FRONTEND=noninteractive apt install -y mysql-server
RUN mkdir /run/mysqld
RUN chown -R mysql:mysql /var/lib/mysql /var/log/mysql /run/mysqld && \
     service mysql start

我能够构建映像而没有任何问题，但是当我执行到容器中并尝试运行mysql时，我得到了错误

docker exec -it myContainer bash
root@fe34sgjd989fh:/root#mysql -uroot -ppassword
mysql: [Warning] Using a password on the command line interface can be insecure.
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

然后我尝试了

root@fe34sgjd989fh:/root#service mysql start
* Starting MySQL database server mysqld                                                                                                                                              [fail]

当我看到/var/log/mysql/error.log时

2019-04-03T22:09:12.829745Z 0 [Note] Server socket created on IP: '127.0.0.1'.
2019-04-03T22:09:12.838374Z 0 [ERROR] Fatal error: Can't open and lock privilege tables: Table storage engine for 'db' doesn't have this option

2019-04-03T22:09:12.838597Z 0 [ERROR] Aborting

是什么意思？这是我的mysql.cnf文件

#
# The MySQL database server configuration file.
#
# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
#
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

# This will be passed to all mysql clients
# It has been reported that passwords should be enclosed with ticks/quotes
# escpecially if they contain "#" chars...
# Remember to edit /etc/mysql/debian.cnf when changing the socket location.

# Here is entries for some specific programs
# The following values assume you have at least 32M ram

我在做什么错？我想用mysql运行为Docker容器加注标

Answer 1

码头工人文件无法在构建阶段运行service mysql start，因为ubuntu的码头工人镜像没有service与之对话的系统管理器。

基于扩展讨论，建议您使用上游mysql容器并将功能扩展到不同的容器中，并使用docker-compose收集它们以一起开始。
