當(dāng)建站之星出現(xiàn)數(shù)據(jù)庫連接失敗時,以下因素需要優(yōu)先排查:
針對CentOS 7系統(tǒng)防火墻,執(zhí)行以下命令序列:
systemctl status firewalld
firewall-cmd --permanent --add-port=3306/tcp
firewall-cmd --add-service=mysql --permanent
firewall-cmd --reload
方向 | 協(xié)議 | 端口 | 源地址 |
---|---|---|---|
入站 | TCP | 3306 | 應(yīng)用服務(wù)器IP |
完成防火墻設(shè)置后仍需驗證:
telnet 數(shù)據(jù)庫IP 3306
測試端口連通性解決建站之星數(shù)據(jù)庫連接問題需采用系統(tǒng)化方法,防火墻配置要確保端口開放與服務(wù)例外雙重驗證,同時配合網(wǎng)絡(luò)策略檢查、數(shù)據(jù)庫權(quán)限審計等多維度排查手段。建議運維人員保存常用端口檢測命令和云平臺安全組配置模板以提高排查效率。
