這里我們拉取官方的鏡像,標簽為5.6
runoob@runoob:~/mysql$ docker pull mysql:5.6
等待下載完成后,我們就可以在本地鏡像列表里查到REPOSITORY為mysql,標簽為5.6的鏡像。

創建Dockerfile
首先,創建目錄mysql,用于存放后面的相關東西。
runoob@runoob:~$ mkdir -p ~/mysql/data ~/mysql/logs ~/mysql/conf
data目錄將映射為mysql容器配置的數據文件存放路徑
logs目錄將映射為mysql容器的日志目錄
conf目錄里的配置文件將映射為mysql容器的配置文件
進入創建的mysql目錄,創建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 } $1 == "[mysqld]" && c == 0 { c = 1; system("cat") }' /etc/mysql/my.cnf > /tmp/my.cnf \ && mv /tmp/my.cnf /etc/mysql/my.cnf VOLUME /var/lib/mysql COPY docker-entrypoint.sh /usr/local/bin/ RUN ln -s usr/local/bin/docker-entrypoint.sh /entrypoint.sh # backwards compat ENTRYPOINT ["docker-entrypoint.sh"] EXPOSE 3306 CMD ["mysqld"]
通過Dockerfile創建一個鏡像,替換成你自己的名字
runoob@runoob:~/mysql$ docker build -t mysql .
創建完成后,我們可以在本地的鏡像列表里查找到剛剛創建的鏡像
runoob@runoob:~/mysql$ docker images |grep mysql mysql 5.6 2c0964ec182a 3 weeks ago 329 MB
runoob@runoob:~/mysql$ docker run -p 3306:3306 --name mymysql -v $PWD/conf:/etc/mysql/conf.d -v $PWD/logs:/logs -v $PWD/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.6 21cb89213c93d805c5bacf1028a0da7b5c5852761ba81327e6b99bb3ea89930e runoob@runoob:~/mysql$
命令說明:
-p 3306:3306:將容器的 3306 端口映射到主機的 3306 端口。
-v $PWD/conf:/etc/mysql/conf.d:將主機當前目錄下的 conf/my.cnf 掛載到容器的 /etc/mysql/my.cnf。
-v $PWD/logs:/logs:將主機當前目錄下的 logs 目錄掛載到容器的 /logs。
-v $PWD/data:/var/lib/mysql :將主機當前目錄下的data目錄掛載到容器的 /var/lib/mysql 。
-e MYSQL_ROOT_PASSWORD=123456:初始化 root 用戶的密碼。
runoob@runoob:~/mysql$ docker ps CONTAINER ID IMAGE COMMAND ... PORTS NAMES 21cb89213c93 mysql:5.6 "docker-entrypoint.sh" ... 0.0.0.0:3306->3306/tcp mymysql

最新官方MySQL(5.7.19)的docker鏡像在創建時映射的配置文件目錄有所不同,在此記錄并分享給大家:
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.
大概意思是說:
MySQL(5.7.19)的默認配置文件是 /etc/mysql/my.cnf 文件。如果想要自定義配置,建議向 /etc/mysql/conf.d 目錄中創建 .cnf 文件。新建的文件可以任意起名,只要保證后綴名是 cnf 即可。新建的文件中的配置項可以覆蓋 /etc/mysql/my.cnf 中的配置項。
具體操作:
首先需要創建將要映射到容器中的目錄以及.cnf文件,然后再創建容器
# 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
命令說明:
查看容器運行情況
# docker ps CONTAINER ID IMAGE COMMAND ... PORTS NAMES 4ec4f56455ea c73c7527c03a "docker-entrypoint.sh" ... 0.0.0.0:3306->3306/tcp mysql

-p 3306:3306:將容器的3306端口映射到主機的3306端口
-v /opt/docker_v/mysql/conf:/etc/mysql/conf.d:將主機/opt/docker_v/mysql/conf目錄掛載到容器的/etc/mysql/conf.d
-e MYSQL_ROOT_PASSWORD=123456:初始化root用戶的密碼
-d: 后臺運行容器,并返回容器ID
