Docker 部署 MySQL 8

1. 拉取镜像

直接去 dockerhub 就行，找自己想要的镜像版本：https://hub.docker.com/_/mysql

拉取镜像：docker pull mysql:8

我这里打算直接用 8 ，则使用上面的命令，如果选择别的tag，直接替换即可。

2. 启动容器并挂载目录

docker run --restart always \
    --name mysql8 \
    -p 3307:3306 \
    -p 33070:33060 \
    -v /usr/soft/mysql-3307/mysql-files:/var/lib/mysql-files \
    -v /usr/soft/mysql-3307/data:/var/lib/mysql \
    -v /usr/soft/mysql-3307/conf.d:/etc/mysql/conf.d  \
    -v /usr/soft/mysql-3307/etc.mysql:/etc/mysql  \
    -e MYSQL_ROOT_PASSWORD=	abc23456\
    -d mysql:8 \
    --character-set-server=utf8mb4 \
    --collation-server=utf8mb4_general_ci \
    --default_authentication_plugin=mysql_native_password

这里-e MYSQL_ROOT_PASSWORD直接指定root密码：abc23456

异常

1. 未挂载目录 /var/lib/mysql-files

报错信息：

Failed to access directory for --secure-file-priv. Please make sure that directory exists and is accessible by MySQL Server. Supplied value : /var/lib/mysql-files

在启动容器时，添加挂载目录：-v /usr/soft/mysql-3307/mysql-files:/var/lib/mysql-files

2. Navicat 连接报错：2059-Authentication plugin caching_sha2_password cannot be load…

给容器配置参数：--default_authentication_plugin=mysql_native_password

在启动容器的命令最后，添加该参数。

改成这样之后，虽然可以正常启动了，但是看下日志，有个提醒：

可以看到 提示不建议使用，这里可以改为：

--character-set-server=utf8mb4 \
--collation-server=utf8mb4_general_ci \
