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:
#在此頁面,找到mysql.default_socket、mysqli.default_socket 、pdo_mysql.default_socket資訊:
#SQL
##
#SQL
#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: Welcome to the MySQL monitor. Commands end with ; or \g.

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### ######5.重啟nginx或apache ###### ######5.重啟nginx或apache ######更多PHP相關知識,請造訪###PHP中文網###! ###
