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

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

之前处理过的 mysql 忘记密码处理，都是在 linux 上的

思路和处理方式是同样的，可是具体操做起来，mac 上仍是不同！

一、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 登陆管理员权限 sudo su ” ，实际照着操做一下就明白了！ 开始总觉得和过去的 sudo + 命令 方式同样的！ 如下就是个人错误过程

$ 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## 二、

$ 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

二、个人过程记录

请原谅！其实我都是照抄的！

1. 查找个人 mysql 在哪里 $ which mysql /usr/local/mysql/bin/mysql

2. 进入 su $ sudo su sh-3.2#

   这是重点！后续实际上和 linux 上同样了 后续命令都是在这个 # 方式下

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

   [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

4. sh-3.2# ./mysql 返回结果以下：

   Welcome to the MySQL monitor.  Commands end with ; or \g.
    Your MySQL connection id is 6

    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; 返回结果以下：

Query OK, 0 rows affected (0.00 sec)

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

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

整个过程以下所示：

三、测试一下

再打开一个 Terminal $ mysql -u root -p 返回结果以下：

Enter password: 
	Welcome to the MySQL monitor.  Commands end with ; or \g.
	Your MySQL connection id is 486
	Server version: 5.7.21 MySQL Community Server (GPL)

	mysql

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

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

四、 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 以下图所示，直接复制一份 config.sample.php 到 config.inc.php 命令行方式这里就再也不列举了！不是重点！ No such file or directory 指的是没有 config.inc.php 这个文件！ 修改如下 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
