背景

希望在 windows10 的 WSL 中安装 mysql。

推荐使用root用户，或者在每条命令前面加上sudo

安装

1.1-寻找 mysql

搜索MySQL：

  [bash]
1
2
sudo apt update
sudo apt search mysql-server

如下：

mysql-server/jammy-updates,jammy-security 8.0.35-0ubuntu0.22.04.1 all
  MySQL database server (metapackage depending on the latest version)

1.2-指定版本

  [bash]
1
sudo apt install mysql-server

1.3-安装完成后登录

  [plaintext]
1
mysql -uroot -p

5.7 默认密码应该是空，但是 8.0 需要密码，通过下面方式查看

  [bash]
1
sudo cat /etc/mysql/debian.cnf

dh@d:~$ sudo cat /etc/mysql/debian.cnf
# Automatically generated for Debian scripts. DO NOT TOUCH!
[client]
host     = localhost
user     = debian-sys-maint
password = 4qqwwJNFI7mzyIsZ
socket   = /var/run/mysqld/mysqld.sock
[mysql_upgrade]
host     = localhost
user     = debian-sys-maint
password = 4qqwwJNFI7mzyIsZ
socket   = /var/run/mysqld/mysqld.sock

我们通过这个账户密码登录：debian-sys-maint/4qqwwJNFI7mzyIsZ

  [bash]
1
mysql -udebian-sys-maint -p

修改配置

配置文件修改

首先需要改变MySQL的配置,执行

  [bash]
1
sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf

将找到 bind-address = 127.0.0.1 并注释掉 → # bind-address = 127.0.0.1 （如下图）

把下面 2 行都注释掉：

  [ini]
1
2
3
4
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
#bind-address           = 127.0.0.1
#mysqlx-bind-address    = 127.0.0.1

同时把端口从 3306 改为 13306

#

#
user            = mysql
# pid-file      = /var/run/mysqld/mysqld.pid
# socket        = /var/run/mysqld/mysqld.sock
port            = 13306
# datadir       = /var/lib/mysql


# If MySQL is running as a replication slave, this should be
# changed. Ref https://dev.mysql.com/doc/refman/8.0/en/server-system-variables.html#sysvar_tmpdir
# tmpdir                = /tmp
#
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
#bind-address           = 127.0.0.1
#mysqlx-bind-address    = 127.0.0.1
#
# * Fine Tuning
#
key_buffer_size         = 16M
# max_allowed_packet    = 64M
# thread_stack          = 256K

如果你想 Binlog

[mysqld] 下面添加如下内容：s

  [ini]

# Enable binary replication log and set the prefix, expiration, and log format.
# The prefix is arbitrary, expiration can be short for integration tests but would
# be longer on a production system. Row-level info is required for ingest to work.
# Server ID is required, but this will vary on production systems
server-id         = 223344
log_bin           = mysql-bin
expire_logs_days  = 10
binlog_format     = row
binlog_row_image  = FULL

# enable gtid mode
gtid_mode = on
enforce_gtid_consistency = on

启动后确认 mysql 结果如下则说明成功：

创建 newroot 账户

在 MySQL 中，要创建一个新的用户（例如 root），设置密码并初始化所有权限，您可以使用以下步骤：

  1. 登录到 MySQL：

      [bash]
    1
     mysql -u root -p

    输入您当前的 root 用户密码。

  2. 创建新用户：

    在 MySQL 提示符下，运行以下 SQL 命令以创建新用户（假设您要创建一个名为 newroot 的用户）：

      [sql]
    1
     CREATE USER 'newroot'@'localhost' IDENTIFIED BY '123456';

    这将创建一个名为 newroot 的用户，限定其只能从本地主机登录，并设置密码为 ‘123456’。

  3. 授予权限：

    为了给新用户赋予所有权限，可以使用以下 SQL 命令：

      [sql]
    1
     GRANT ALL PRIVILEGES ON *.* TO 'newroot'@'localhost' WITH GRANT OPTION;

    这将为用户 newroot 赋予所有数据库和表的权限，并允许他授予权限给其他用户。

  4. 刷新权限：

    在修改权限后，需要刷新 MySQL 的权限缓存：

      [sql]
    1
     FLUSH PRIVILEGES;

    这会使新的权限立即生效。

  5. 退出 MySQL：

      [sql]
    1
     exit;

    退出 MySQL 提示符。

现在，您已经创建了一个名为 newroot 的用户，密码为 ‘123456’，并且该用户拥有所有数据库和表的权限。

  1. 登录验证：
  [plaintext]
1
mysql -unewroot -p

可以正常登录即可。

创建一个支持远程访问的用户

newroot/123456 登录上去：

  [plaintext]
1
mysql -unewroot -p

执行：

  [sql]
1
2
3
CREATE USER 'admin'@'%' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'admin'@'%' WITH GRANT OPTION;
flush privileges;

新增远程访问用户和用户密码 admin/123456

测试：

  [plaintext]
1
msql -uadmin -p

登录验证。

    update_time timestamp default CURRENT_TIMESTAMP not null on update CURRENT_TIMESTAMP comment '更新时间'

查看 WSL 对应的 ip

WSL 中使用 ifconfig，查看对应的 ip 为 172.24.20.97

                .password("123456")
                .url("jdbc:mysql://172.24.20.97:13306/migrate?useSSL=false&serverTimezone=Asia/Shanghai")
                .init()
                .execute();

System.out.println(JSON.toJSON(list));

是可以测试成功的。
