mkdir /var/lib/mysql/ Vi /etc/my.cnf

把前面的部分修改为:

[client] #password       = your_password port            = 3306 socket          = /var/lib/mysql/mysql.sock default-character-set=utf8 # Here follows entries for some specific programs   # The MySQL server [mysqld] character-set-server=utf8 language=/usr/share/mysql/english/ port            = 3306 socket          = /var/lib/mysql/mysql.sock skip-name-resolve #skip-locking   key_buffer = 100M max_allowed_packet = 1M table_cache = 1200 sort_buffer_size = 16M net_buffer_length = 64K read_buffer_size = 200M read_rnd_buffer_size = 100M myisam_sort_buffer_size = 100M query_cache_size= 200M query_cache_limit= 64M thread_cache_size=60   key_buffer_size= 200M table_open_cache=1000 table_cache=1200 thread_cache_size=60 query_cache_size= 200M query_cache_limit= 200M table_definition_cache=1200 myisam_data_pointer_size=7 delayed_queue_size=2000 preload_buffer_size=65536 delayed_queue_size=20 preload_buffer_size=1024   #innodb_read_ahead_threshold=2   innodb_buffer_pool_size= 200M ; innodb_additional_mem_pool= 16M ; thread_concurrency = 2
