这篇文章主要介绍了MySQL 5.5如何设置配置文件，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。 在MySQL数据库中，可以没有配置文件，在这种情况下，MySQL会安装编译时的默认参数设置启动实例 用以下命令查看，当MYSQL数据库实例启动时，它会在哪些位置查找配置文件 [root@localhost test]# mysql --help | grep my.cnf order of preference, my.cnf, $MYSQL_TCP_PORT, /etc/my.cnf /etc/mysql/my.cnf /usr/etc/my.cnf ~/.my.cnf MySQL里面有启动参数、系统参数，启动参数通过show variables无法查询到，可以在mysqld的选项中查到 例如关于二进制日志有Startup Options Used with Binary Logging、System Variables Used with Binary Logging两种参数 [root@localhost log]# mysqld --verbose --help > 02.txt [root@localhost log]# vim 02.txt .. --binlog-do-db=name Tells the master it should log updates for the specified database, and exclude all others not explicitly mentioned. .. [root@localhost log]# vim /etc/my.cnf .. # log server-id = 10000 log-bin = /log/binlog/mysql-bin binlog_format = MIXED binlog-do-db = test [root@localhost data]# vim /etc/my.cnf [client] port = 3306 socket=/mysql_data/70005/mysql.sock # Mysql server [mysqld] port = 3306 user = mysql socket=/mysql_data/70005/mysql.sock pid-file = /mysql_data/70005/mysqld.pid basedir = /software datadir = /data #tmpdir = open_files_limit = 10240 max_connections = 500 max_connect_errors = 100000 sql_mode = NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES wait_timeout = 100 # Cache table_open_cache = 400 thread_cache_size = 300 # Buffer max_allowed_packet = 256M max_heap_table_size = 256M net_buffer_length = 8K sort_buffer_size = 4M join_buffer_size = 2M read_buffer_size = 2M read_rnd_buffer_size = 16M #query_cache_size = 32M # Log server-id = 1 log-bin = /log/binlog/mysql-bin sync_binlog = 2 binlog_cache_size = 32M max_binlog_cache_size = 512M max_binlog_size = 512M binlog_format = MIXED #binlog_cache_use = 100 #binlog_cache_disk_use = 50 log_output = FILE log_error = /log/err.log slow_query_log = 1 slow_query_log_file = /log/slow_query.log long_query_time = 10 log-short-format = 0 log_slow_admin_statements = 0 log_queries_not_using_indexes = 0 #log_throttle_queries_not_using_indexes = 0 log_slow_slave_statements = 0 general_log = 0 general_log_file = /log/general_query.log # InnoDB innodb_data_file_path = ibdata1:12M:autoextend:max:100G #innodb_data_file_path = /ibdata/ibdata1:12M:autoextend:max:100G innodb_data_home_dir = /ibdata innodb_file_per_table = 1 innodb_log_group_home_dir = /log/innodb #innodb_log_file_size = 256M #innodb_log_files_in_group = 3 innodb_log_buffer_size = 8M innodb_buffer_pool_size = 100M # InnoDB undo __ Mysql 5.6 or higher #innodb_undo_directory = /log/undo #innodb_undo_tablespaces = 2 #innodb_undo_logs = 200 innodb_fast_shutdown = 1 innodb_flush_log_at_trx_commit = 1 innodb_buffer_pool_instances = 5 # MyISAM #skip-external-locking #key_buffer_size = 128M #myisam_sort_buffer_size = 64M # Character set #character_set_server = gbk #collation_server = gbk_bin # Federated storage engine federated # Transaction init_connect='SET autocommit=0' [mysql] no-auto-rehash default-character-set = gbk [mysqldump] quick max_allowed_packet = 16M [myisamchk] #key_buffer_size = 256M #sort_buffer_size = 256M #read_buffer = 2M #write_buffer = 2M [mysqlhotcopy] #interactive-timeout 感谢你能够认真阅读完这篇文章，希望小编分享的“MySQL 5.5如何设置配置文件”这篇文章对大家有帮助。 （编辑：92站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
