昨天一位 VPS 客戶說他的 WordPress 博客沒了，網(wǎng)站可以打開，但是文章都沒了，懷疑被黑。我們登陸客戶 VPS 后沒發(fā)現(xiàn)被黑跡象，然后進(jìn)入 MySQL 數(shù)據(jù)庫發(fā)現(xiàn) Table ‘./wordpress/wp_posts’ is marked as crashed and should be repaired 錯誤，因為 wp_posts 表被損壞了，所以 WordPress 的文章都顯示不出來：
# mysql -u root -p
Enter password:
mysql> use wordpress;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
mysql> select * from wp_posts;
ERROR 145 (HY000): Table './wordpress/wp_posts' is marked as crashed and should be repaired
mysql> Bye
修復(fù) MySQL 數(shù)據(jù)庫數(shù)據(jù)表問題可以由 mysqlcheck 來解決，先用 mysqlcheck 查看一下：
# mysqlcheck -u root -p wordpress
Enter password:
然后添加 –auto-repair 參數(shù)自動修復(fù)，最好修復(fù)前備份一下數(shù)據(jù)庫：
# mysqldump -u root -p wordpress > wordpress.sql
Enter password:
# mysqlcheck -u root -p wordpress --auto-repair
