[英]MySQL - ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
[英]ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) in OSX
我正在嘗試使用我在 XAMPP conf 文件中的用戶密碼登錄 mysql,但是我收到以下錯誤:
mysql -u mysql -p; 1 ✘ at 11:48:02 AM
Enter password:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
我在下面的conf文件/Applications/XAMPP/xamppfiles/etc/my.cnf
中輸入了1234
作為密碼:
# The following options will be passed to all MySQL clients
[client]
password =1234
port =3306
socket =/Applications/XAMPP/xamppfiles/var/mysql/mysql.sock
# Here follows entries for some specific programs
# The MySQL server
default-character-set=utf8mb4
[mysqld]
user=mysql
port=3306
socket =/Applications/XAMPP/xamppfiles/var/mysql/mysql.sock
key_buffer=16M
max_allowed_packet=1M
table_open_cache=64
sort_buffer_size=512K
net_buffer_length=8K
read_buffer_size=256K
read_rnd_buffer_size=512K
myisam_sort_buffer_size=8M
此外,這是運行 mysql 守護進程的信息:

這是我在 XAMPP 中看到的:
我有 OSX Catalina 10.15.7 (19H1713)。
在取消注釋密碼並將其設置為1234
后,我停止並在 XAMPP UI 中啟動了 mySQL,但仍然無法登錄。
我輸入如下,但仍然沒有進入 mysql shell: mysql -u mysql -h 127.0.0.1 -port 3306 -p 1234;
我看到類似的東西:
mysql: [Warning] Using a password on the command line interface can be insecure.

--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.)
不傳遞端口信息(因為 3306 是默認端口),我收到此錯誤,盡管1234
是我在 xampp 的 mysql conf 文件中設置的密碼):
mysql -u mysql -h 127.0.0.1 -p; 1 ✘ at 12:29:02 PM
Enter password:
ERROR 1045 (28000): Access denied for user 'mysql'@'localhost' (using password: YES)
mysql -u root -h 127.0.0.1 -p; 1 ✘ at 12:34:13 PM
Enter password:
當它要求輸入密碼時,按回車,你現在在 mysql shell 中。 您可以在此處查看現有用戶列表:
mysql> SELECT user FROM mysql.user;
+------+
| user |
+------+
| root |
| root |
| |
| pma |
| root |
+------+
現在,創建一個用戶並為其設置密碼,例如:
mysql> CREATE USER 'mona'@'localhost' IDENTIFIED BY '1234';
Query OK, 0 rows affected (0.01 sec)
mysql> SELECT user FROM mysql.user;
+------+
| user |
+------+
| root |
| root |
| |
| mona |
| pma |
| root |
+------+
6 rows in set (0.00 sec)
現在退出mysql shell,在提示符前輸入以下命令:
mysql -u mona -h 127.0.0.1 -p;
和密碼輸入1234
。
您現在進入用戶mona
的 mysql shell。
