标签： mysql tomcat docker web-applications

我试图使用Docker将使用Hibernate，XAMPP for Apache tomcat和mysql服务器的Windows应用程序移植到Linux上。

在我完成以下步骤后，我的web.app的第一个功能是登录/注册表单：在Windows上一切正常，但是容器有几十分钟的延迟..有时候有还有500个http错误!!

  1. docker run -d --name mysql-phpmyadmin -p 127.0.0.1:8686:80 -p 127.0.0.1:3306:3306 grzesiekb/mysql-phpmyadmin

  2. docker run -d -p 8484:8080 -p 8007:8009 --name tomcat8-linked --link mysql-phpmyadmin:mysqlphp tomcat:8.0-jre8然后在webapps /文件夹下部署我的warfile

  3. 在我的hibernate.cfg.xml中，您可以看到它here（我有问题以可查看的方式粘贴它）：）

  4. 在我的mysql容器my.cnf中有：

    5.   

    [客户]       port = 3306       socket = /var/run/mysqld/mysqld.sock 

    # Here is entries for some specific programs
# The following values assume you have at least 32M ram

# This was formally known as [safe_mysqld]. Both versions are currently parsed.

# * InnoDB
#
# InnoDB is enabled by default with a 10MB datafile in /var/lib/mysql/.
# Read the manual for more InnoDB related options. There are many!
#
# * Security Features
#
# Read the manual, too, if you want chroot!
# chroot = /var/lib/mysql/
#
# For generating SSL certificates I recommend the OpenSSL GUI "tinyca".

# ssl-ca=/etc/mysql/cacert.pem

# * IMPORTANT: Additional settings that can override those from this file!
#   The files must end with '.cnf', otherwise they'll be ignored.

    1. 默认情况下，这个mysql容器只允许来自localhost的连接：为了允许来自任何地方的连接，我已经完成了：

      在上授予所有权限。以及＆＃39; root＆＃39; @＆＃39;％＆＃39;通过＆＃39;密码识别＆＃39; WITH GRANT OPTION;  FLUSH PRIVILEGES;

      2. 然后我通过phpmyadmin

      导入了我的dql转储

      描述您收到的结果：

      巨大的延迟，与我不知道哪个问题有关，并且以随机的方式无法连接到mysql。没有日志。我的老师说这可能是与Docker网络相关的DNS问题。

      描述您期望的结果：

      立即连接到数据库，就像使用XAMPP的Windows

      一样

答案 0 :(得分：1)

您应该尽量使您的设置成为标准，以避免因非标准做法而导致的错误。
