1.數據庫權限問題:開放權限
grant [權限] on [數據庫名].[表名] to ['用戶名']@['web服務器的ip地址'] identified by ['密碼'];
- grant all on *.* to 'root'@'%' identified by 'root';
或者指定IP地址
- grant all on *.* to 'root'@'192.168.1.103' identified by 'root';
2.Linux防火牆
臨時關閉 :當Linux服務器重啓時防火牆重新啓動
- service iptables stop 關閉防火牆
- service iptables start 啓動防火牆
- systemctl status firewalld --查看防火牆狀態
- systemctl start firewalld --開啓防火牆
- systemctl stop firewalld --關閉防火牆
永久關閉:
- chkconfig iptables off 關閉
- chkconfig iptables on 開啓
3.本身主機防火牆問題
