创建MySQL安装目录

mkdir -p /opt/mysql/{
    
    data,conf,logs}

创建my.cnf

tee /opt/mysql/conf/my.cnf <<EOF

max_connections=1000
# innodb的dml操作的行级锁的等待时间
innodb_lock_wait_timeout=500
# 设置mysql服务端默认字符集

安装部署

docker-compose -f /opt/mysql/mysql5.7.31-docker-compose.yaml pull
docker-compose -f /opt/mysql/mysql5.7.31-docker-compose.yaml up -d

创建数据库、创建用户、用户授权数据库所有权限
