錯誤：嘗試重新啓動mysql時

Question

我正在嘗試重新啓動mysql服務，但以下錯誤日誌令我感到不安。 幫我出離情... 這裏是配置文件.. 的my.cnf：

[mysqld] 
bind-address = 0.0.0.0 
#server-id = 2 
#master-host=192.168.10.110 
#master-connect-retry=60 
#master-user=slave 
#master-password=slave 
#replicate-do-db=repltest 
max_connections=500 
datadir=/var/lib/mysql 
socket=/var/lib/mysql/mysql.sock 
user=mysql 

symbolic-links=0 

在這裏，我附加日誌文件的詳細信息... 日誌文件：

Answer 1

嘗試更新/升級MySQL。 或重置mysql.user表，它已損壞。 因爲日誌說：

Fatal error: mysql.user table is damaged. Please run mysql_upgrade.
