Can't access Phpmyadmin in ubuntu error mysqli_real_connect(): (HY000/2002)

Question

我试图访问 phpmyadmin 但是这件事发生了

 MySQL said: Documentation

 Cannot connect: invalid settings.
 mysqli_real_connect(): (HY000/2002): No such file or directory
 Connection for controluser as defined in your configuration failed.
 mysqli_real_connect(): (HY000/2002): No such file or directory
 phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection. You should 
 check the host, username and password in your configuration and make sure that they correspond to 
 the information given by the administrator of the MySQL server.

apache 和 mysql 正在运行，我的网站出现这样的错误

Warning: session_start(): open(/opt/lampp/temp//sess_ku01nv1mbiroo8btvpbqjv47f7, O_RDWR) failed: Permission denied (13) in /opt/lampp/htdocs/sisfo/index.php on line 2

有谁知道如何解决这一问题？

Answer 1

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

似乎 phpmyadmin 尝试连接到 mysql 套接字（不存在？）。 您可以尝试将config.inc.php中的主机从localhost更改为127.0.0.1 。

Warning: session_start(): open(...) failed: Permission denied (13)

您可能对临时文件夹有错误的权限/所有权。 在 shell 中尝试以下命令：

chmod 777 /opt/lampp/temp
chown -R 33:33 /opt/lampp/temp
