MySQL8 Docker容器化部署之C86架构（海光CPU）

一、简介

本文介绍如何在海光 C86 架构的服务器上安装并配置MySQL 8 。

二、引言

适用于国产化CPU硬件服务器：如海光 C86-5280等
以及适用于不支持x86-64-v2指令集的CPU：Fatal glibc error: CPU does not support x86-64-v2
替换为不要求 x86-64-v2 的 MySQL 镜像，如：Debian 系列、mysql:8.0.36

详解

1、创建目录

bash 复制代码

>> mkdir -p /opt/software/mysql8/{conf,init} /data/mysql8/{backup,data}

2、编辑docker-compose.yml

bash 复制代码

>> cd /opt/software/mysql8/
>> vim docker-compose.yml  # 内容如下，复制粘贴即可

yml 复制代码

---
# 定义密钥
secrets:
  passwd_root:
    file: ./secrets/passwd_root.txt

# 服务
services:
  mysql8:
    container_name: mysql-common
    image: mysql:8.0.44-debian
    user: "999:999"
    restart: unless-stopped
    privileged: true  # 授予容器最高系统权限；获得对宿主机的完全访问控制权
    ports:
      - 30096:3306  # 宿主机指定网卡映射
    volumes:
      - /data/mysql8/data:/var/lib/mysql
      - ./conf/my.cnf:/etc/mysql/my.cnf:ro
      - ./logs:/var/log/mysql
      - ./init:/docker-entrypoint-initdb.d 
      - /etc/localtime:/etc/localtime:ro

    secrets:  # 挂载secrets; 默认挂载至容器内的 /run/secrets/ 路径
      - passwd_root

    environment:
      TZ: Asia/Shanghai
      MYSQL_ROOT_PASSWORD_FILE: "/run/secrets/passwd_root"

    healthcheck:
      test: ["CMD-SHELL", "MYSQL_PWD=\"$$(cat /run/secrets/passwd_root)\" mysql -h 127.0.0.1 -uroot --protocol=TCP -e 'SELECT 1' >/dev/null 2>&1 || exit 1"]
      interval: 10s
      timeout: 5s
      retries: 5
      start_period: 60s
...

3、编辑my.cnf

bash 复制代码

>> vim ./conf/my.cnf

c 复制代码

4、创建初始化脚本

bash 复制代码

# 编辑密码文件
>> echo "super@ADMIN_2026" > ./secrets/passwd_root.txt

>> vim ./init/init.sql  # 可根据需要自定义

sql 复制代码

create user 'common'@'%' identified with mysql_native_password by "jiazhi@admin_123";
grant all privileges on *.* to 'common'@'%'  WITH GRANT OPTION;
flush privileges;

5、启动MySQL

bash 复制代码

# 授权
>> chown -R 999:999 /data/mysql8/ /opt/software/mysql8/
>> chmod -R 755 /data/mysql8/ /opt/software/mysql8/

# 启动MySQL
>> docker-compose up -d

# 若后续修改了配置文件后，则重启即可，不会影响现有数据
>> docker-compose restart
