Kadang, untuk mengimpor database yang cukup besar ke localhost tidak jarang MySQL mengeluarkan error “MySQL has gone away”. Hal ini diakibatkan dari konfigurasi yang tidak optimal. Namun, sebelum melakukan perubahan di my.conf nya backup terlebih dahulu.
Buka file my.cnf dengan notepad++ / editor lainya
d:\xampp\mysql\bin\my.ini
kemudian kopi paste kode ini.
pastikan service mysql nya dalam keadaan mati.

However, in case you choose this method, then # start replication for the first time (even unsuccessfully, for example # if you mistyped the password in master-password and the slave fails to # connect), the slave will create a master.info file, and any later # change in this file to the variables' values below will be ignored and # overridden by the content of the master.info file, unless you shutdown # the slave server, delete master.info and restart the slaver server. # For that reason, you may want to leave the lines below untouched # (commented) and instead use CHANGE MASTER TO (see above) # # required unique id between 2 and 2^32 - 1 # (and different from the master) # defaults to 2 if master-host is set # but will not function as a slave if omitted #server-id = 2 # # The replication master for this slave - required #master-host = <hostname> # # The username the slave will use for authentication when connecting # to the master - required #master-user = <username> # # The password the slave will authenticate with when connecting to # the master - required #master-password = <password> # # The port the master is listening on. # optional - defaults to 3306 #master-port = <port> # # binary logging - not required for slaves, but recommended #log-bin=mysql-bin # Point the following paths to different dedicated disks #tmpdir = "D:/xampp/tmp" #log-update = /path-to-dedicated-directory/hostname # Uncomment the following if you are using BDB tables #bdb_cache_size = 4M #bdb_max_lock = 10000 back_log = 20 interactive_timeout = 7200 wait_timeout = 7200 net_read_timeout = 120 net_write_timeout = 300 sort_buffer_size = 2M read_buffer_size = 2M read_rnd_buffer_size = 8M join_buffer_size = 4M tmp_table_size = 128M max_heap_table_size = 128M query_cache_type = 1 query_cache_size = 128M query_cache_limit = 4M max_connections = 150 thread_cache_size= 32 open_files_limit = 65535 table_definition_cache = 4000 table_open_cache = 4000 # Comment the following if you are using InnoDB tables #skip-innodb innodb_data_home_dir = "D:/xampp/mysql/data" innodb_data_file_path = ibdata1:10M:autoextend innodb_log_group_home_dir = "D:/xampp/mysql/data" #innodb_log_arch_dir = "D:/xampp/mysql/data" ## You can set .._buffer_pool_size up to 50 - 80 % ## of RAM but beware of setting memory usage too high innodb_buffer_pool_size = 300M innodb_additional_mem_pool_size = 2M ## Set .._log_file_size to 25 % of buffer pool size innodb_log_file_size = 300M innodb_log_buffer_size = 32M innodb_flush_log_at_trx_commit = 2 innodb_lock_wait_timeout = 50 ## UTF 8 Settings #init-connect=\'SET NAMES utf8\' #collation_server=utf8_unicode_ci #character_set_server=utf8 #skip-character-set-client-handshake #character_sets-dir="D:/xampp/mysql/share/charsets" [mysqldump] quick max_allowed_packet = 128M innodb_force_recovery = 1 [mysql] no-auto-rehash # Remove the next comment character if you are not familiar with SQL #safe-updates [isamchk] key_buffer = 20M sort_buffer_size = 20M read_buffer = 2M write_buffer = 2M [myisamchk] key_buffer = 20M sort_buffer_size = 20M read_buffer = 2M write_buffer = 2M [mysqlhotcopy] interactive-timeout
