php不連接資料庫?

PHP連線不上MySQL解決方案總結

1. 取得目前mysql.default_socket、mysqli.default_socket、pdo_mysql.default_socket 設定資訊

#建立一個PHP 檔案, 顯示phpinfo():

用瀏覽器開啟:

#2. 取得MySQL socket 路徑

 

 #SQL

#2. 取得MySQL socket 路徑

透過主機進入控制台進入MySQL , 輸入指令: STATUS, 尋找UNIX socket 值

#mysql -u root -p
Enter password:

3. 這時候, 你比較mysql.default_socket、mysqli.default_socket、pdo_mysql.default_socket 和透過MyIX sockSQL 發現不一樣,這就是mysql_connect(); 警告的原因: PHP 配置mysql 有問題.

 4. 重新配置PHP, 打開php.ini修改mysql.default_socket、mysqli.default_socket、pdo_my修改.default_socketsql.default_socketsql.default_socketsql.default_socketsql.default_socketsql.default_socketsql.default_socketsql.default_socketsql.的值為: /tmp/mysql.sock 

pdo_mysql.default_socket=/tmp/mysql.sock  
mysql.default_socket=/tmp/mysql.sock  
mysqli.default_socket=/tmp/mysql.sock
###或修改my.cnf的socket:###
[client]  
socket=/tmp/mysql.sock  
  
[mysqld]  
socket=/tmp/mysql.sock
