WordPress docker 容器不以 mysql:latest image 开头

Question

我已经用 mariadb 容器设置了 wordpress，没有任何问题。

现在我正在尝试用 mysql 测试 wordpress。

使用的命令：

$ docker run --name mysql01 -e MYSQL_ROOT_PASSWORD=Password1234 -d mysql
$ docker run --name wordpress01 --link mysql01 -p 8080:80 -e WORDPRESS_DB_HOST=mysql01:3306 -e WORDPRESS_DB_USER=root -e WORDPRESS_DB_PASSWORD=Password1234 -e WORDPRESS_DB_NAME=wordpress -e WORDPRESS_TABLE_PREFIX=wp_ -d wordpress

容器状态：

$ docker ps 
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                 NAMES
e71299679e73        mysql               "docker-entrypoint..."   2 minutes ago       Up 2 minutes        3306/tcp, 33060/tcp   mysql01

$ docker ps -a 
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                     PORTS                 NAMES

e71299679e73        mysql               "docker-entrypoint..."   7 minutes ago       Up 7 minutes               3306/tcp, 33060/tcp   mysql01

错误日志：

$ docker logs wordpress01

正如here 所述，默认情况下，WordPress 无法与 MySQL v8 一起使用。此外，wordpress docker image readme 中的示例使用 MySQL v5.7。将 mysql 版本更改为 5.7 应该可以完成这项工作。

docker run --name mysql01 -e MYSQL_ROOT_PASSWORD=Password1234 -d mysql:5.7

如果您需要使用mysql:latest docker 映像，使用--default-authentication-plugin=mysql_native_password 参数启动mysql 也应该像here 中提到的那样工作。

docker run --name mysql01 -e MYSQL_ROOT_PASSWORD=Password1234 -d mysql --default-authentication-plugin=mysql_native_password
