[ERROR] /usr/sbin/MySQLd: Table './daifans/wp_options' is marked as crashed and should be repaired
- 在网上查了文档，说是表损坏，所以 WordPress 的文章都显示不出来，需要修复，修复前需要备份
我备份时也出错了，说是损坏的那个表备份不了的意思，我就用排除废表备份其他的
# mysqldump -uroot -p dbname --ignore-table=dbname.tablename --ignore-table=dbname.tablename2 --ignore-table=dbname.tablename3 > dump.sql
然后添加 –auto-repair 参数自动修复
# mysqlcheck -u root -p daifans --auto-repair
