解决方案

创建在scripts目录下mysqld启动脚本

#!/bin/bash#Fromhttps://github.com/docker-library/mysql/issues/99set-e#failonanyerrorecho'*WorkingaroundpermissionerrorsinDockeronMaclocallybymakingsurethat"mysql"usesthesameuidandgidasthehostvolume'TARGET_UID=$(stat-c"%u"/var/lib/mysql)echo'--Settingmysqlusertouseuid'$TARGET_UIDusermod-o-u$TARGET_UIDmysql||trueTARGET_GID=$(stat-c"%g"/var/lib/mysql)echo'--Settingmysqlgrouptousegid'$TARGET_GIDgroupmod-o-g$TARGET_GIDmysql||trueechoecho'*StartingMySQL'chown-Rmysql:root/var/run/mysqld//entrypoint.shmysqld--user=mysql--console

创建docker-compose.py，指定run-mysqld.sh脚本为容器入口

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

运行docker-compose up命令，启动容器
