6 进入mysql 容器，使用root用户和密码登录mysql数据库，查看是否有wordpress数据库？
[root@localhost ~]# docker exec -it 5c /bin/bash
root@5c0368eaca68:/# mysql -uroot -p000000
mysql: [Warning] Using a password on the command line interface can be insecure.

mysql>
有wordpress数据库
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| sys |
| wordpress |
+--------------------+
5 rows in set (0.01 sec)
没有表
mysql> use wordpress;
Database changed
mysql> show tables;
Empty set (0.00 sec)
7 在外网（物理机）的浏览器 使用http:// 容器宿主机的ip：HostPort 访问wordpress站点。如下图所示：
再次进入mysql 容器，使用root用户和密码登录mysql数据库，进入wordpress数据库，再查看是否有表？
有表了
mysql> show tables;
+-----------------------+
| Tables_in_wordpress |
+-----------------------+
| wp_commentmeta |
| wp_comments |
| wp_links |
| wp_options |
| wp_postmeta |
| wp_posts |
| wp_term_relationships |
| wp_term_taxonomy |
| wp_termmeta |
| wp_terms |
| wp_usermeta |
| wp_users |
+-----------------------+
12 rows in set (0.00 sec)
最后值得注意的是：wordpress启动后一定要先查看日志看是否启动正常，如果有apache服务启动有问题可能跟docker
版本、iptables服务有关，mysql至少要用5.6版本以上不要用太新的版本没那么稳定，这里我用的是拉的是mysql5.7。
如果遇到问题可以在评论区大家一起讨论一起学习
