我使用 Vagrant 安装了一台新的 VirtualBox 机器,并在该 VM 内安装了 Mysql Server。如何连接到虚拟机外部的服务器?我已经转发了 Vagrantfile 的端口 3306 ,但是当我尝试连接到 mysql 服务器时,它重新发布并显示错误: '读取初始通信数据包'
ERROR 2013 (HY000): Lost connection to MySQL server at 'reading initial communication packet', system error: 0
确保 MySQL 绑定到 0.0.0.0 而不是 127.0.0.1,否则将无法从机器外部访问它
您可以通过编辑
/etc/mysql/my.conf
文件并查找 bind-address
项目来确保这一点 - 您希望它看起来像 bind-address = 0.0.0.0
。然后保存并重新启动MySQL:
sudo service mysql restart
如果您在生产服务器上执行此操作,您需要了解安全隐患,此处讨论:https://serverfault.com/questions/257513/how-bad-is-setting-mysqls-bind-address -到-0-0-0-0
使用
ssh [email protected] -p 2222
(密码 vagrant)登录您的盒子
然后:
sudo nano /etc/mysql/my.cnf
并用#注释掉以下行
#skip-external-locking
#bind-address
保存并退出
然后:
sudo service mysql restart
然后您可以通过 SSH 连接到您的 MySQL 服务器。
我最近遇到了这个问题。我使用 PuPHPet 生成配置。
要通过 SSH 连接到 MySQL,“vagrant”密码对我不起作用,而是必须通过 SSH 密钥文件进行身份验证。
连接 MySQL Workbench
连接方法
基于 SSH 的标准 TCP/IP
SSH
Hostname: 127.0.0.1:2222 (forwarded SSH port)
Username: vagrant
Password: (do not use)
SSH Key File: C:\vagrantpath\puphpet\files\dot\ssh\insecure_private_key
(Locate your insercure_private_key)
MySQL
Server Port: 3306
username: (root, or username)
password: (password)
测试连接。
对于任何尝试使用 mysql workbench 或续集专业版执行此操作的人,这些是输入:
Mysql Host: 192.168.56.101 (or ip that you choose for it)
username: root (or mysql username u created)
password: **** (your mysql password)
database: optional
port: optional (unless you chose another port, defaults to 3306)
ssh host: 192.168.56.101 (or ip that you choose for this vm, like above)
ssh user: vagrant (vagrants default username)
ssh password: vagrant (vagrants default password)
ssh port: optional (unless you chose another)
好吧,由于给定的回复都没有帮助我,我不得不查看更多内容,并在this文章中找到了解决方案。
简而言之,答案如下:
使用 MySQL Workbench 连接到 MySQL
Connection Method: Standard TCP/IP over SSH
SSH Hostname: <Local VM IP Address (set in PuPHPet)>
SSH Username: vagrant (the default username)
SSH Password: vagrant (the default password)
MySQL Hostname: 127.0.0.1
MySQL Server Port: 3306
Username: root
Password: <MySQL Root Password (set in PuPHPet)>
使用给定的方法,我能够使用 MySQL Workbench 以及 Valentina Studio 从主机 Ubuntu 机器连接到 vagrant 中的 mysql 数据库。
以下是登录框后对我有用的步骤:
找到MySQL配置文件:
$ mysql --help | grep -A 1 "Default options"
Default options are read from the following files in the given order: /etc/my.cnf /etc/mysql/my.cnf ~/.my.cnf
在 Ubuntu 16 上,路径通常为
/etc/mysql/mysql.conf.d/mysqld.cnf
更改绑定地址的配置文件:
如果存在,请按如下方式更改值。如果不存在,请将其添加到 [mysqld] 部分的任意位置。
bind-address = 0.0.0.0
保存对配置文件的更改并重新启动 MySQL 服务。
service mysql restart
创建/授予数据库用户访问权限:
以root用户连接MySQL数据库,执行以下SQL命令:
mysql> CREATE USER 'username'@'%' IDENTIFIED BY 'password';
mysql> GRANT ALL PRIVILEGES ON mydb.* TO 'username'@'%';
这对我有用:在 Vagrant 中连接到 MySQL
username: vagrant password: vagrant
sudo apt-get update sudo apt-get install build-essential zlib1g-dev
git-core sqlite3 libsqlite3-dev sudo aptitude install mysql-server
mysql-client
sudo nano /etc/mysql/my.cnf change: bind-address = 0.0.0.0
mysql -u root -p
use mysql GRANT ALL ON *.* to root@'33.33.33.1' IDENTIFIED BY
'jarvis'; FLUSH PRIVILEGES; exit
sudo /etc/init.d/mysql restart
