网友投稿 841 2022-05-29

提示

:本文的操作是在基础环境搭建完成的基础上进行的,基础环境搭建请参阅上一篇文章:

鲲鹏服务器快速部署docker+docker-compose环境:

https://bbs.huaweicloud.com/forum/thread-60765-1-1.html

或:

https://bbs.huaweicloud.com/blogs/176180

docker环境搭建完成,可以进行本文的操作。

系统环境:CentOS 7.6 64bit with ARM

构建Mysql 8.0.19镜像

构建准备

# clone 官方Dockerfile

git clone https://github.com/mysql/mysql-docker.git

# 进入8.0路径

cd mysql-docker/8.0

# 修改原版Dockerfile,mysql版本号修改为8.0.19,其他不动

# mysql版本号修改为8.0.19是我方项目需要,如果需要其版本,请参考执行

vim Dockerfile

FROM oraclelinux:7-slim

# 版本号改为8.0.19

ARG MYSQL_SERVER_PACKAGE=mysql-community-server-minimal-8.0.19

ARG MYSQL_SHELL_PACKAGE=mysql-shell-8.0.19

# Install server

RUN yum install -y https://repo.mysql.com/mysql-community-minimal-release-el7.rpm \

https://repo.mysql.com/mysql-community-release-el7.rpm \

&& yum-config-manager --enable mysql80-server-minimal \

&& yum install -y \

$MYSQL_SERVER_PACKAGE \

libpwquality \

&& yum clean all \

&& mkdir /docker-entrypoint-initdb.d

# Data Volume

VOLUME /var/lib/mysql

COPY docker-entrypoint.sh /entrypoint.sh

COPY healthcheck.sh /healthcheck.sh

ENTRYPOINT ["/entrypoint.sh"]

HEALTHCHECK CMD /healthcheck.sh

EXPOSE 3306 33060

CMD ["mysqld"]

修改完成,保存、退出。

构建镜像

# 构建镜像,注意末尾有个空格,还有个.

docker build -t cehc/mysql-arm:8.0.19 .

# 查看镜像

docker images

# cehc/mysql-arm:8.0.19镜像大小438M

发布镜像

docker login

# 输入在docker-hub注册的用户名密码登录

docker tag cehc/mysql-arm:8.0.19 cehc/mysql-arm:8.0.19

docker push cehc/mysql-arm:8.0.19

# 推送成功

说明

:cehc/mysql-arm:8.0.19镜像已经发布为公共镜像。

测试镜像

# 测试运行,不挂载数据目录和自定义配置

docker run --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=root -d cehc/mysql-arm:8.0.19

# 查看启动日志

docker logs -f -t --tail 100 mysql

# 启动成功后,可进入 mysql 容器

docker exec -it mysql /bin/bash

# 在容器内登录mysql

mysql -uroot -p

# 查看 lower_case_table_names 参数设置

mysql> show variables like 'lower%';

# 查看mysql当前时间,检查当前时区

mysql> select curtime();

# 退出mysql

mysql> exit;

# 退出容器

exit

# 停止容器

docker stop mysql

# 删除容器

docker rm mysql

实测通过

镜像编排

# 部署前,主机挂载数据盘到/data,准备数据目录

mkdir -p /data/mysql/conf

cd /data/mysql

mkdir data log run backup mysql-files tmp

chmod -R 777 /data/mysql

chmod -R 644 /data/mysql/conf

# 说明:容器挂载 /data/mysql:/data/mysql 为了方便进行备份/恢复操作

# 根据容器内置my.cnf,编制自定义配置

vim /data/mysql/conf/my.cnf

# 内容如下:

# For advice on how to change settings please see

# http://dev.mysql.com/doc/refman/8.0/en/server-configuration-defaults.html

# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.

#

# Remove leading # to turn on a very important data integrity option: logging

# changes to the binary log between backups.

构建自定义mysql镜像

在前面操作的基础上集成自定义配置,根据我方项目开发实际需求,构建自定义mysql镜像。
