Docker 安装 MySQL

Docker 安装 MySQL

---

方法一、docker pull mysql

查找 Docker Hub 上的 mysql 镜像：

docker search mysql

这里我们拉取官方的镜像，标签为 5.6：

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：

docker images | grep mysql

---

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。

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

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

docker build -t mysql .

使用 mysql 镜像

运行镜像，生成容器

使用 docker run 命令运行镜像，并设置容器中 mysql 数据库的 root 账号密码为 password：

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

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=password：初始化 root 用户的密码

 

访问容器

使用 docker exec 命令访问容器 5c576d19d6b1，并使用 root/password 账号密码访问 MySQL 数据库：

docker exec -it 5c576d19d6b1 /bin/bash
service mysql status
mysql -uroot -p
show databases;

创建 miracle 数据库，luna 数据表，测试 MySQL 的可用性：

create database miracle;
show databases;
use miracle;
create table luna ( name varchar(20), age int(3), sex varchar(5));
select * from luna;
