Docker 安裝 MySQL

方法1、經過 Dockerfile構建

建立Dockerfilemysql

首先，建立目錄mysql,用於存放後面的相關東西。git

runoob@runoob:~$ mkdir -p ~/mysql/data ~/mysql/logs ~/mysql/conf

data目錄將映射爲mysql容器配置的數據文件存放路徑github

logs目錄將映射爲mysql容器的日誌目錄web

conf目錄裏的配置文件將映射爲mysql容器的配置文件redis

進入建立的mysql目錄，建立Dockerfilesql

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"]

經過Dockerfile建立一個鏡像，替換成你本身的名字docker

runoob@runoob:~/mysql$ docker build -t mysql .

建立完成後，咱們能夠在本地的鏡像列表裏查找到剛剛建立的鏡像api

runoob@runoob:~/mysql$ docker images |grep mysql

方法2、docker pull mysql

查找Docker Hub上的mysql鏡像

runoob@runoob:/mysql$ docker search mysql

這裏咱們拉取官方的鏡像,標籤爲5.6

runoob@runoob:~/mysql$ docker pull mysql:5.6

等待下載完成後，咱們就能夠在本地鏡像列表裏查到REPOSITORY爲mysql,標籤爲5.6的鏡像。

使用mysql鏡像

運行容器

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 -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。

查看容器啓動狀況

runoob@runoob:~/mysql$ docker ps

1 篇筆記

  1.    Brian

      153***2799@qq.com

    最新官方MySQL(5.7.19)的docker鏡像在建立時映射的配置文件目錄有所不一樣，在此記錄並分享給你們：

    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。若是想要自定義配置，建議向 /etc/mysql/conf.d 目錄中建立 .cnf 文件。新建的文件能夠任意起名，只要保證後綴名是 cnf 便可。新建的文件中的配置項能夠覆蓋 /etc/mysql/my.cnf 中的配置項。

    具體操做：

    首先須要建立將要映射到容器中的目錄以及.cnf文件，而後再建立容器

    # 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：

    • -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: 後臺運行容器，並返回容器ID
    • imageID: mysql鏡像ID

    查看容器運行狀況

    # docker ps
CONTAINER ID IMAGE          COMMAND          ... PORTS                    NAMES
4ec4f56455ea c73c7527c03a  "docker-entrypoint.sh" ... 0.0.0.0:3306->3306/tcp   mysql

 

Docker 安裝 Redis

方法1、經過 Dockerfile 構建

建立Dockerfile

首先，建立目錄redis,用於存放後面的相關東西。

runoob@runoob:~$ mkdir -p ~/redis ~/redis/data

data目錄將映射爲redis容器配置的/data目錄,做爲redis數據持久化的存儲目錄

進入建立的redis目錄，建立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 redis && useradd -r -g redis redis

RUN apt-get update && apt-get install -y --no-install-recommends \
                ca-certificates \
                wget \
        && rm -rf /var/lib/apt/lists/*

# grab gosu for easy step-down from root
ENV GOSU_VERSION 1.7
RUN set -x \
        && 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

ENV REDIS_VERSION 3.2.0
ENV REDIS_DOWNLOAD_URL http://download.redis.io/releases/redis-3.2.0.tar.gz
ENV REDIS_DOWNLOAD_SHA1 0c1820931094369c8cc19fc1be62f598bc5961ca

# for redis-sentinel see: http://redis.io/topics/sentinel
RUN buildDeps='gcc libc6-dev make' \
        && set -x \
        && apt-get update && apt-get install -y $buildDeps --no-install-recommends \
        && rm -rf /var/lib/apt/lists/* \
        && wget -O redis.tar.gz "$REDIS_DOWNLOAD_URL" \
        && echo "$REDIS_DOWNLOAD_SHA1 *redis.tar.gz" | sha1sum -c - \
        && mkdir -p /usr/src/redis \
        && tar -xzf redis.tar.gz -C /usr/src/redis --strip-components=1 \
        && rm redis.tar.gz \
        && make -C /usr/src/redis \
        && make -C /usr/src/redis install \
        && rm -r /usr/src/redis \
        && apt-get purge -y --auto-remove $buildDeps

RUN mkdir /data && chown redis:redis /data
VOLUME /data
WORKDIR /data

COPY docker-entrypoint.sh /usr/local/bin/
ENTRYPOINT ["docker-entrypoint.sh"]

EXPOSE 6379
CMD [ "redis-server" ]

經過Dockerfile建立一個鏡像，替換成你本身的名字

runoob@runoob:~/redis$ docker build  -t redis:3.2 .

建立完成後，咱們能夠在本地的鏡像列表裏查找到剛剛建立的鏡像
