Brothers, My mysql server can't start after I edited the my.cnf. It can only use the default setting to start up........why? It said "timeout when starting mysql..." my my.cnf : [mysqld] skip-locking skip-innodb query_cache_limit=1M query_cache_size=32M query_cache_type=1 max_connections=500 interactive_timeout=100 wait_timeout=100 connect_timeout=10 thread_cache_size=128 key_buffer=16M join_buffer=1M max_allowed_packet=16M table_cache=1024 record_buffer=1M sort_buffer_size=2M read_buffer_size=2M max_connect_errors=10 # Try number of CPU's*2 for thread_concurrency thread_concurrency=2 myisam_sort_buffer_size=64M log-bin server-id=1 [safe_mysqld] err-log=/var/log/mysqld.log open_files_limit=8192 [mysqldump] quick max_allowed_packet=16M [mysql] no-auto-rehash #safe-updates [isamchk] key_buffer=64M sort_buffer=64M read_buffer=16M write_buffer=16M [myisamchk] key_buffer=64M sort_buffer=64M read_buffer=16M write_buffer=16M [mysqlhotcopy] interactive-timeout
