我发现docker有官方的MySQL镜像here .不幸的是，我无法使用主机卷启动容器。我试过以下脚本。

DB_ROOT_PASS="myPassword"
DB_NAME="myDatabase"
DATA_DIR="$HOME/mysql_data"

mkdir -p $DATA_DIR
mkdir -p $DATA_DIR/conf.d

cd $DATA_DIR
wget -O my.cnf http://pastebin.com/raw.php?i=aV4pXRQD

sudo docker run \
-e MYSQL_ROOT_PASSWORD=$DB_ROOT_PASS \
-e MYSQL_DATABASE=$DB_NAME \
-p 3306:3306 \
-v $DATA_DIR:/etc/mysql \
mysql

结果如下:

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

  /usr/bin/mysqladmin -u root password 'new-password'
  /usr/bin/mysqladmin -u root -h 2efc65e86051 password 'new-password'

Alternatively you can run:

  /usr/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:

  cd /usr ; /usr/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl

  cd mysql-test ; perl mysql-test-run.pl

WARNING: Found existing config file /usr/my.cnf on the system.
Because this file might be in use, it was not replaced,
but was used in bootstrap (unless you used --defaults-file)
and when you later start the server.
The new default config file was created as /usr/my-new.cnf,
please compare it with your file and take the changes you need.

WARNING: Default config file /etc/mysql/my.cnf exists on the system
This file will be read by default by the MySQL server
If you do not want to use this, either remove it, or use the
--defaults-file argument to mysqld_safe when starting the server

我也尝试过不创建 conf.d 目录或 my.cnf 文件，这也会导致其他错误。

为什么需要卷？

主机卷提供“近金属”磁盘性能以及数据持久性，这对于 MySQL 数据库很重要。因此，不需要从容器备份数据，或者使用“数据容器”模式。

问题:

如何更新脚本以使用主机卷启动 Docker MySQL 容器，从而使 My​​SQL 服务正确启动？也许传递初始化脚本或向卷添加更多数据？

上下文

• Ubuntu 14.04 64 位服务器
• Docker 版本 1.5.0，构建 a8a31ef

最佳答案

有几个问题，主要是正在下载的原始配置文件有一个 bind-address 设置，导致无法从外部连接到 mysql 服务主持人。我已经更新了设置(将其注释掉)并使服务正常运行，但是 service mysql status 仍然显示 MySQL Community Server 5.6.23 is not running. 即使这是。我 99% 确定这是因为“容器化”效应。

另外，数据也没有保存在/etc/mysql，所以为了持久化和更高的性能，我们需要再增加一个volume。最终的工作脚本如下:

DB_ROOT_PASS="myPassword"
DB_NAME="myDatabase"
CONFIG_DIR="$HOME/mysql_config"
DATA_DIR="$HOME/mysql_data"

mkdir -p $DATA_DIR
mkdir -p $CONFIG_DIR
mkdir -p $CONFIG_DIR/conf.d

cd $CONFIG_DIR
sudo wget -O my.cnf http://pastebin.com/raw.php?i=aV4pXRQD

sudo docker run \
-e MYSQL_ROOT_PASSWORD=$DB_ROOT_PASS \
-e MYSQL_DATABASE=$DB_NAME \
-p 3306:3306 \
-v $CONFIG_DIR:/etc/mysql \
-v $DATA_DIR:/var/lib/mysql \
-d \
mysql
