我的目标是拥有一个具有运行MySQL服务的docker容器.所以每当我启动容器时,数据库都处于初始状态并且MySQL正在运行.
几乎一切都很好但是当我启动容器时MySQL服务没有运行.每次在控制台中我都必须像这样启动它：service mysql start.
以下是我构建和运行容器的步骤：
$docker build -t executer:mysql .
Sending build context to Docker daemon 15.87 kB
Sending build context to Docker daemon
Step 0 : FROM debian:wheezy
#
# ... Many steps without error
#
Step 17 : RUN mysql_install_db --user=mysql --basedir=/usr/ --ldata=/var/lib/mysql/
---> Using cache
---> 1c71bf4524f0
Step 18 : RUN service mysql start
---> Running in b4643765b79b
......
MySQL Community Server 5.6.24 is started.

$docker run --rm -it executer:mysql /bin/bash

这是Dockerfile的内容：
FROM debian:wheezy
# add our user and group first to make sure their IDs get assigned consistently,regardless of whatever dependencies get added
RUN groupadd -r mysql && useradd -r -g mysql mysql
# FATAL ERROR: please install the following Perl modules before executing /usr/local/mysql/scripts/mysql_install_db:
# File::Basename
# File::Copy
# Sys::Hostname
# Data::Dumper
RUN apt-get update && apt-get install -y perl --no-install-recommends && rm -rf /var/lib/apt/lists/*
# gpg: key 5072E1F5: public key "MySQL Release Engineering
运行我的容器后,如何更改我的Dockerfile以运行MySQL服务？
最佳答案
我试过你的设置
见https://github.com/BITPlan/docker-stackoverflowanswers/tree/master/33299303
我先得到了
E: Version '5.6.24*' for 'mysql-server' was not found
这与你的问题无关,但需要修复.
所以我注释掉你的大部分Dockerfile并添加：
RUN apt-get install mysql-server-5.5
这给了：
E：无法找到包mysql-server-5.5
这是特定于发行版的,所以我将FROM行更改为
FROM ubuntu:14.04
我更熟悉
然后我修改了Dockerfile来改变
RUN service mysql start
至
CMD service mysql start
正如michaelbahr的评论中所提到的那样
./run
和
root@96ff34b4e0c0:/# service --status-all 2>&1 | grep mysql
结果显示：
[ ? ] mysql
你在那里 – mysql运行.
您可能希望相应地修复Dockerfile. （编辑：商洛站长网）
