我正在尝试设置一个运行多个wordpress网站的docker-compose应用程序，共享一个单个mysql容器。
以下是相应的version: '3.3'
services:
##################
# Gateway Server #

# NOTE: nginx is included for completenes, but (a priori) not
# relevant to the issue at hand.
nginx:

restart: always
depends_on:
- site0

volumes:

###################
# Wordpress Sites #

site0:
image: wordpress:latest
restart: always
depends_on:

env_file:
- ./wordpress/wordpress.env # contains `WORDPRESS_DB_HOST=mysql:3306`

mysql由于多个wordpress站点将共享/docker-entrypoint-initdb.d/容器，因此使用环境变量初始化users / tables / non-root-password已不再可行。因此，我在CREATE DATABASE site0;
CREATE USER 'site0'@'localhost' IDENTIFIED BY 'supersecretpassword';
GRANT ALL PRIVILEGES ON site0.* TO 'site0'@'localhost';
FLUSH PRIVILEGES;

docker-compose up运行mysql会从mysql_1 | 2018-03-12T11:09:28.787698Z 2 [Note] Access denied for user 'site0'@'172.18.0.3' (using password: YES)
生成以下输出：
site0由site0_1 | MySQL Connection Error: (1045) Access denied for user 'site0'@'172.18.0.3' (using password: YES)
site0_1 |
site0_1 | Warning: mysqli::__construct(): (HY000/1045): Access denied for user 'site0'@'172.18.0.3' (using password: YES) in Standard input code on line 22
容器回显：

在日志输出中，当调用mysql init脚本时，我们得到：
$ docker exec -ti wpsvc_mysql_1 bash
$ mysql -uroot -psupersecretpassword
mysql> SELECT EXISTS(SELECT * FROM mysql.user WHERE user = 'site0');
+-------------------------------------------------------+

1 row in set (0.00 sec)

我首先要检查是否实际在mysql容器中创建了表，用户和密码：
site0在./wordpress/site0/.env和./mysql/wpinit.sql中仔细检查{{1}}的数据库密码是否完全相同后，我来这里匆匆忙忙。
我做错了什么？
答案 0 :(得分：1)
我建议尝试'site0'@'%'，因为它不会从同一主机调用。
