                        Docker 安装 MySQL
方法一、docker pull mysql
查找Docker Hub上的mysql镜像
[Bash shell] 纯文本查看 复制代码
runoob@runoob:/mysql$ docker search mysql

...
这里我们拉取官方的镜像,标签为5.6
[Bash shell] 纯文本查看 复制代码
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。
[Bash shell] 纯文本查看 复制代码
runoob@runoob:~/mysql$ docker images |grep mysql
mysql               5.6                 2c0964ec182a        3 weeks ago         329 MB
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。
[Bash shell] 纯文本查看 复制代码
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
[Bash shell] 纯文本查看 复制代码
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\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
[Bash shell] 纯文本查看 复制代码
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
[Bash shell] 纯文本查看 复制代码
runoob@runoob:~/mysql$ docker images |grep mysql
mysql               5.6                 2c0964ec182a        3 weeks ago         329 MB

使用mysql镜像运行容器
[Bash shell] 纯文本查看 复制代码
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 $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
[Bash shell] 纯文本查看 复制代码
runoob@runoob:~/mysql$ docker ps 
CONTAINER ID    IMAGE         COMMAND                  ...  PORTS                    NAMES
21cb89213c93    mysql:5.6    "docker-entrypoint.sh"    ...  0.0.0.0:3306->3306/tcp   mymysql
