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。

方法二、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。

1
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.asc "https://github.com/tianon/gosu/releases/download/$GOSU_VERSION/gosu-$(dpkg --print-architecture).asc" \

ENV MYSQL_MAJOR 5.6
ENV MYSQL_VERSION 5.6.31-1debian8

RUN echo “deb http://repo.mysql.com/apt/deb… 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\nskip-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”]

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 $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。
