mysql无法重启，急急！！

Starting nginx...  done
Starting MySQL.. ERROR! The server quit without updating PID file (/usr/local/mysql/var/li476-187.pid).





key_buffer_size=16777216
read_buffer_size=262144
max_used_connections=0
max_threads=151
thread_count=0
connection_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 134092 K  bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
