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\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"]

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/my.cnf:/etc/mysql/my.cnf -v $PWD/logs:/logs -v $PWD/data:/mysql_data -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 $PWD/conf/my.cnf:/etc/mysql/my.cnf：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:/mysql_data：将主机当前目录下的data目录挂载到容器的/mysql_data
• -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
