在macosx下如果指定本地目錄替換/var/lib/mysql，運(yùn)行時(shí)會(huì)出現(xiàn)文件權(quán)限的錯(cuò)誤，導(dǎo)致mysqld無法正常運(yùn)行

創(chuàng)建在scripts目錄下mysqld啟動(dòng)腳本

#!/bin/bash
# From https://github.com/docker-library/mysql/issues/99
set -e # fail on any error

echo "* Working around permission errors in Docker on Mac locally by making sure that "mysql" uses the same uid and gid as the host volume"
TARGET_UID=$(stat -c "%u" /var/lib/mysql)
echo "-- Setting mysql user to use uid "$TARGET_UID
usermod -o -u $TARGET_UID mysql || true
TARGET_GID=$(stat -c "%g" /var/lib/mysql)
echo "-- Setting mysql group to use gid "$TARGET_GID
groupmod -o -g $TARGET_GID mysql || true
echo
echo "* Starting MySQL"
chown -R mysql:root /var/run/mysqld/
/entrypoint.sh mysqld --user=mysql --console

創(chuàng)建docker-compose.py，指定run-mysqld.sh腳本為容器入口

test-mysql:
    image: mysql 
    ports:
        - "3306:3306"
    volumes:   
        - /localhost/mysql/data:/var/lib/mysql 
        - ./scripts/run-mysqld.sh:/run-mysqld.sh
    environment:
        - MYSQL_DATABASE=play
        - MYSQL_USER=play
        - MYSQL_PASSWORD=play
        - MYSQL_ROOT_PASSWORD=123456
    entrypoint: /run-mysqld.sh

運(yùn)行docker-compose up命令，啟動(dòng)容器
