Mac mysql 忘记 root 密码，phpmyadmin 登录 No such file or directory 错误处理

20190629 mac 上安装过 mysql 和 phpmyadmin之后，很久没有使用（本机硬盘空间有限），今天想用的时候，死活输入不对密码了！

以前处理过的 mysql 忘记密码处理，都是在 linux 上的

思路和处理方式是一样的，但是具体操作起来，mac 上还是不一样！

1、参考

https://blog.csdn.net/liu_yanzhao/article/details/79427005

开始没有明白参考博客中 “ 回车后登录管理员权限 sudo su ” ，实际照着操作一下就明白了！开始总以为和过去的 sudo + 命令方式一样的！以下就是我的错误过程

$ sudo ./mysqld_safe --skip-grant-tables &

[1] 2070
dhbm-on-mac20180816:bin dhbm$ sudo ./mysqld_safe --skip-grant-tables &./mysql
[2] 2105
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

[1]+  Stopped                 sudo ./mysqld_safe --skip-grant-tables## 2、

$ sudo ./mysql

Password:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

[4]+  Stopped                 sudo ./mysqld_safe --skip-grant-tables

2、我的过程记录

请原谅！其实我都是照抄的！

查找我的 mysql 在哪里$ which mysql/usr/local/mysql/bin/mysql
进入 su$ sudo sush-3.2#
这是重点！后续实际上和 linux 上一样了后续命令都是在这个 # 方式下

禁止mysql验证功能sh-3.2# ./mysqld_safe --skip-grant-tables &返回结果如下：

 [1] 2141
 sh-3.2# 2019-06-29T08:05:37.6NZ mysqld_safe Logging to '/usr/local/mysql-5.7.21-macos10.13-x86_64/data/dhbm-on-mac20180816.local.err'.
 2019-06-29T08:05:38.6NZ mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql-5.7.21-macos10.13-x86_64/data

sh-3.2# ./mysql返回结果如下：

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

这就进入到 mysql> 命令方式了！

5.mysql> FLUSH PRIVILEGES;返回结果如下：

Query OK, 0 rows affected (0.00 sec)

6.mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('123456');返回结果如下：

Query OK, 0 rows affected, 1 warning (0.00 sec)

整个过程如下所示：

3、测试一下

再打开一个 Terminal$ mysql -u root -p返回结果如下：

	Enter password:

打开浏览器http://localhost/phpMyAdmin-4.8.0.1-all-languages/index.php输入 root /123456 之后还是错误啊！

mysqli_real_connect(): (HY000/2002): No such file or directory

4、 mysqli_real_connect(): (HY000/2002): No such file or directory 错误处理

正好我使用了 PHPStorm 打开了这个 phpmyadmin，目录结构一目了然如下图所示，直接复制一份 config.sample.php 到 config.inc.php命令行方式这里就不再列举了！不是重点！No such file or directory 指的是没有 config.inc.php 这个文件！修改以下 2 处//$cfg['Servers'][$i]['host'] = 'localhost';//by wzh 20190629$cfg['Servers'][$i]['host'] = '127.0.0.1';

//$cfg['Servers'][$i]['password'] = '';// by wz h20190629 123456$cfg['Servers'][$i]['password'] = '123456';

再次测试http://127.0.0.1/phpMyAdmin-4.8.0.1-all-languages/index.php
