Question

我的目标是拥有一个运行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.

以下是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:

RUN echo "deb http://repo.mysql.com/apt/debian/ wheezy mysql-${MYSQL_MAJOR}" > /etc/apt/sources.list.d/mysql.list

# the "/var/lib/mysql" stuff here is because the mysql-server postinst doesn't have an explicit way to disable the mysql_install_db codepath besides having a database already "configured" (ie, stuff in /var/lib/mysql/mysql)
# also, we set debconf keys to make APT a little quieter

RUN apt-get update && apt-get install -y procps

# comment out a few problematic configuration values

RUN mysql_install_db --user=mysql --basedir=/usr/ --ldata=/var/lib/mysql/

RUN service mysql start

运行容器后，如何更改Dockerfile以运行MySQL服务？

Answer 1

另一种解决方案是使用MySQL泊坞窗映像： https://hub.docker.com/_/mysql/

您所要做的就是：

docker run --name some-mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:tag

其中：

some-mysql是您要分配给容器的名称
my-secret-pw是为MySQL root用户设置的密码
tag是指定MySQL版本的标签

Answer 2

我尝试了你的设置

请参阅https://github.com/BITPlan/docker-stackoverflowanswers/tree/master/33299303

首先我得到了

RIVO RHYTHM RX40
['Weight ', 'Tag line', 'Model', 'Type', 'Processor', 'Network', 'Connectivity', 'Memory', 'RAM', 'Sim Type', 'Display Type', 'Screen Size', 'Screen Resolution', 'OS', 'Camera', 'Features', 'SIM Modules', 'Battery', 'Warranty', 'Brand', 'Refund Policy']
['0.3430', 'Take Control', 'Rhythm RX40', 'Smart Phone', 'Dual Core', 'N/A', 'N/A', '4GB', '512 mb', 'N/A', 'IPS Display', '4. inches ', 'IPS High Resolution', 'KitKat ', '5 MP', 'IPS Capacitive Touch Screen Display', 'Dual SIM', '1750 mAh', '12', 'Rivo', 'N/A']

与您的问题无关，但需要修复。所以我评论了你的大部分Dockerfile并添加了：

E: Version '5.6.24*' for 'mysql-server' was not found

给出了： E：无法找到包mysql-server-5.5

这是特定于发行版的，因此我将FROM行更改为

RUN apt-get install mysql-server-5.5

我更熟悉

然后我修改了Dockerfile以更改

FROM ubuntu:14.04

到

RUN service mysql start

如michaelbahr的评论中所述，并与

核实

CMD service mysql start

和

./run

示：

root@96ff34b4e0c0:/# service --status-all 2>&1 | grep mysql

你有 - mysql运行。您可能需要相应地修复Dockerfile。
