切换到mysql工作目录

1. 打开cmd 命令面板

WIN+R 调出命令面板, 输入“cmd”命令, 回车确认

2. 找到mysql的安装路径中的bin目录

假如mysql安装到D盘下
cd 切换到bin目录

D:\MySQL\bin>

3. 检查目录是否正确

输入 mysql --version 可以输出版本信息,则所在目录正确

D:\MySQL\bin>mysql --version
mysql  Ver 14.14 Distrib 5.7.23, for Win64 (x86_64)

链接数据库基本命令

mysql -D 数据库名 -P 端口号 -h 主机名或IP地址 -u 用户名 -p密码
  • -p密码: -p与密码中间不能有空格

链接本地数据库

本地数据库,可以使用默认配置 ,root为用户名
mysql -u root -p

D:\MySQL\bin>mysql -u root -p
Enter password: ****
Welcome to the MySQL monitor.  Commands end with ; or \g.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql>

链接远程数据库

假如 远程数据库端口号是3306(默认也是3306),IP地址是 127.0.0.1(默认本地地址也是127.0.0.1),用户名是root
mysql -P 3306 -h 127.0.0.1 -u root -p

D:\MySQL\bin>mysql -P 3306 -h 127.0.0.1 -u root -p
Enter password: ****
Welcome to the MySQL monitor.  Commands end with ; or \g.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

  -I, --help          Synonym for -?
  --auto-rehash       Enable automatic rehashing. One doesn't need to use
                      'rehash' to get table and field completion, but startup
                      and reconnecting may take a longer time. Disable with
                      --disable-auto-rehash.
                      (Defaults to on; use --skip-auto-rehash to disable.)
  -A, --no-auto-rehash
                      No automatic rehashing. One has to use 'rehash' to get
                      table and field completion. This gives a quicker start of
                      mysql and disables rehashing on reconnect.
  --auto-vertical-output
                      Automatically switch to vertical output mode if the

  --enable-cleartext-plugin
                      Enable/disable the clear text authentication plugin.
  -e, --execute=name  Execute command and quit. (Disables --force and history
                      file.)

  -G, --named-commands
                      Enable named commands. Named commands mean this program's
                      internal commands; see mysql> help . When enabled, the
                      named commands can be used from any line of the query,
                      otherwise only from the first line, before an enter.
                      Disable with --disable-named-commands. This option is
                      disabled by default.
  -i, --ignore-spaces Ignore space after function names.

                      The buffer size for TCP/IP and socket communication.

  --binary-mode       By default, ASCII '\0' is disallowed and '\r\n' is
                      translated to '\n'. This switch turns off both features,
                      and also turns off parsing of all clientcommands except
