Docker安装mysql

方法一、通过 Dockerfile构建

创建Dockerfile

首先，创建目录mysql,用于存放后面的相关东西。

runoob@runoob:~$ mkdir -p ~/mysql/data ~/mysql/logs ~/mysql/conf

data目录将映射为mysql容器配置的数据文件存放路径

logs目录将映射为mysql容器的日志目录

conf目录里的配置文件将映射为mysql容器的配置文件

进入创建的mysql目录，创建Dockerfile

FROM debian:jessie

 

# 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

 

# add gosu for easy step-down from root

ENV GOSU_VERSION 1.7

RUN set -x

    && apt-get update && apt-get install -y --no-install-recommends ca-certificates wget && rm -rf /var/lib/apt/lists/*

    && wget -O /usr/local/bin/gosu "https://github.com/tianon/gosu/releases/download/$GOSU_VERSION/gosu-$(dpkg --print-architecture)"

    && wget -O /usr/local/bin/gosu.asc "https://github.com/tianon/gosu/releases/download/$GOSU_VERSION/gosu-$(dpkg --print-architecture).asc"

    && export GNUPGHOME="$(mktemp -d)"

    && gpg --keyserver ha.pool.sks-keyservers.net --recv-keys B42F6819007F00F88E364FD4036A9C25BF357DD4

    && gpg --batch --verify /usr/local/bin/gosu.asc /usr/local/bin/gosu

    && rm -r "$GNUPGHOME" /usr/local/bin/gosu.asc

    && chmod +x /usr/local/bin/gosu

    && gosu nobody true

    && apt-get purge -y --auto-remove ca-certificates wget

 

RUN mkdir /docker-entrypoint-initdb.d

 

# 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 pwgen --no-install-recommends && rm -rf /var/lib/apt/lists/*

 

# gpg: key 5072E1F5: public key "MySQL Release Engineering <mysql-build@oss.oracle.com>" imported

RUN apt-key adv --keyserver ha.pool.sks-keyservers.net --recv-keys A4A9406876FCBD3C456770C88C718D3B5072E1F5

 

ENV MYSQL_MAJOR 5.6

ENV MYSQL_VERSION 5.6.31-1debian8

 

RUN echo "deb http://repo.mysql.com/apt/debian/ jessie 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 {

        echo mysql-community-server mysql-community-server/data-dir select '';

        echo mysql-community-server mysql-community-server/root-pass password '';

        echo mysql-community-server mysql-community-server/re-root-pass password '';

        echo mysql-community-server mysql-community-server/remove-test-db select false;

    } | debconf-set-selections

    && apt-get update && apt-get install -y mysql-server="${MYSQL_VERSION}" && rm -rf /var/lib/apt/lists/*

    && rm -rf /var/lib/mysql && mkdir -p /var/lib/mysql /var/run/mysqld

    && chown -R mysql:mysql /var/lib/mysql /var/run/mysqld

# ensure that /var/run/mysqld (used for socket and lock files) is writable regardless of the UID our mysqld instance ends up having at runtime

    && chmod 777 /var/run/mysqld

 

# comment out a few problematic configuration values

# don't reverse lookup hostnames, they are usually another container

RUN sed -Ei 's/^(bind-address|log)/#&/' /etc/mysql/my.cnf

    && echo 'skip-host-cache skip-name-resolve' | awk '{ print } $1 == "[mysqld]" && c == 0 { c = 1; system("cat") }' /etc/mysql/my.cnf > /tmp/my.cnf

    && mv /tmp/my.cnf /etc/mysql/my.cnf

 

VOLUME /var/lib/mysql

 

COPY docker-entrypoint.sh /usr/local/bin/

RUN ln -s usr/local/bin/docker-entrypoint.sh /entrypoint.sh # backwards compat

ENTRYPOINT ["docker-entrypoint.sh"]

 

EXPOSE 3306

CMD ["mysqld"]

通过Dockerfile创建一个镜像，替换成你自己的名字

runoob@runoob:~/mysql$ docker build -t mysql .

创建完成后，我们可以在本地的镜像列表里查找到刚刚创建的镜像

runoob@runoob:~/mysql$ docker images |grep mysql

mysql               5.6                 2c0964ec182a        3 weeks ago         329 MB

方法二、docker pull mysql

查找Docker Hub上的mysql镜像

runoob@runoob:/mysql$ docker search mysql

...

这里我们拉取官方的镜像,标签为5.6

runoob@runoob:~/mysql$ docker pull mysql:5.6

等待下载完成后，我们就可以在本地镜像列表里查到REPOSITORY为mysql,标签为5.6的镜像。

使用mysql镜像

运行容器

runoob@runoob:~/mysql$ docker run -p 3306:3306 --name mymysql -v $PWD/conf:/etc/mysql/conf.d -v $PWD/logs:/logs -v $PWD/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.6

21cb89213c93d805c5bacf1028a0da7b5c5852761ba81327e6b99bb3ea89930e

runoob@runoob:~/mysql$

命令说明：

  • -p 3306:3306：将容器的 3306 端口映射到主机的 3306 端口。
  • -v -v $PWD/conf:/etc/mysql/conf.d：将主机当前目录下的 conf/my.cnf 挂载到容器的 /etc/mysql/my.cnf。
  • -v $PWD/logs:/logs：将主机当前目录下的 logs 目录挂载到容器的 /logs。
  • -v $PWD/data:/var/lib/mysql ：将主机当前目录下的data目录挂载到容器的 /var/lib/mysql 。
  • -e MYSQL_ROOT_PASSWORD=123456：初始化 root 用户的密码。

查看容器启动情况

runoob@runoob:~/mysql$ docker ps

CONTAINER ID    IMAGE         COMMAND                  ...  PORTS                    NAMES

1 篇笔记

最新官方MySQL(5.7.19)的docker镜像在创建时映射的配置文件目录有所不同，在此记录并分享给大家：

官方原文：

The MySQL startup configuration is specified in the file /etc/mysql/my.cnf, and that file in turn includes any files found in the /etc/mysql/conf.d directory that end with .cnf. Settings in files in this directory will augment and/or override settings in /etc/mysql/my.cnf. If you want to use a customized MySQL configuration, you can create your alternative configuration file in a directory on the host machine and then mount that directory location as /etc/mysql/conf.d inside the mysql container.

大概意思是说：

MySQL(5.7.19)的默认配置文件是 /etc/mysql/my.cnf 文件。如果想要自定义配置，建议向 /etc/mysql/conf.d 目录中创建 .cnf 文件。新建的文件可以任意起名，只要保证后缀名是 cnf 即可。新建的文件中的配置项可以覆盖 /etc/mysql/my.cnf 中的配置项。

具体操作：

首先需要创建将要映射到容器中的目录以及.cnf文件，然后再创建容器

# pwd

/opt

# mkdir -p docker_v/mysql/conf

# cd docker_v/mysql/conf

# touch my.cnf

# docker run -p 3306:3306 --name mysql -v /opt/docker_v/mysql/conf:/etc/mysql/conf.d -e MYSQL_ROOT_PASSWORD=123456 -d imageID

4ec4f56455ea2d6d7251a05b7f308e314051fdad2c26bf3d0f27a9b0c0a71414

命令说明：

  • -p 3306:3306：将容器的3306端口映射到主机的3306端口
  • -v /opt/docker_v/mysql/conf:/etc/mysql/conf.d：将主机/opt/docker_v/mysql/conf目录挂载到容器的/etc/mysql/conf.d
  • -e MYSQL_ROOT_PASSWORD=123456：初始化root用户的密码
  • -d: 后台运行容器，并返回容器ID
  • imageID: mysql镜像ID

查看容器运行情况

# docker ps

CONTAINER ID IMAGE          COMMAND          ... PORTS                    NAMES

4ec4f56455ea c73c7527c03a  "docker-entrypoint.sh" ... 0.0.0.0:3306->3306/tcp   mysql
