MySQL 5.5 trên Ubuntu 10.10 được sử dụng để hoạt động tốt cho đến ngày hôm qua nhưng hôm nay bất cứ khi nào tôi bắt đầu sử dụng MySQL mysqld_safe
với tư cách là người dùng root, nó sẽ hiển thị
Starting mysqld daemon with databases from /var/lib/mysql
và sau đó cho thấy pid ended
Gần đây tôi không chạy bất kỳ bản cập nhật nào nhưng tôi đã sử dụng quản trị viên MySQL để kết nối với cơ sở dữ liệu từ xa nhưng quản trị viên MySQL đã được cài đặt một tháng trước.
Sau đó tôi đã kiểm tra tệp lỗi error.log và tìm thấy điều này:
120210 02:33:23 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql

đi như thế này
