docker封装mysql镜像
- 2020 年 3 月 17 日
- 笔记
一、概述
直接使用官方的镜像
docker pull mysql:5.7
但是mysqld.cnf并没有优化，还是默认的。
二、封装镜像
创建目录
# dockerfile目录 mkdir -p /opt/dockerfile/mysql # 持久化目录 mkdir -p /data/mysql/data
/opt/dockerfile/mysql 目录结构如下：
./ ├── dockerfile ├── mysqld.cnf └── run.sh
dockerfile
FROM mysql:5.7 ADD mysqld.cnf /etc/mysql/mysql.conf.d/mysqld.cnf
mysqld.cnf

run.sh
#!/bin/bash docker run -d --name mysqld_prod --restart=always -e MYSQL_ROOT_PASSWORD=123456 -p 3306:3306 -v /data/mysql/data:/var/lib/mysql mysqld_prod:5.7 --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
生成镜像
cd /opt/dockerfile/mysql docker build -t mysqld_prod:5.7 .
启动镜像
bash run.sh
三、测试连接
