我看過好多關於Linux下沒有my.cnf的部落格,都是什麼rmp安裝沒有my.cnf檔案啊,然後什麼兩個方法啊,我就無語了,大家要是知道就不會查資料了,你們敢不敢負責點?說詳細點?有的說從 /usr/share/MySQL
裡複製一個.cnf檔案到 /etc 下,有用嗎?配置檔案資料不給別人,複製個毛線?複製誰都會!
my.cnf 配置檔案:
- # For advice on how to change settings please see
- # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
- # *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
- # *** default location during install, and will be replaced if you
- # *** upgrade to a newer version of MySQL.
- [mysqld]
- #innodb
- # Remove leading
- # and set to the amount of RAM for the most important data
- # cache in MySQL. Start at 70% of total RAM for dedicated server, else10%.
- innodb_buffer_pool_size = 4000M
- innodb_additional_mem_pool_size=60M
- innodb_data_home_dir=
- innodb_date_file_path=ibdata1:20M:autoextend
- innodb_log_group_home_dir=/var/log/innodb_log
- innodb_log_files_in_group=2
- innodb_log_file_size=30M
- innodb_log_buffer_size=3M
- innodb_doublewrite=ON
- innodb_open_file=2000

- query_cache_size=10M
- sor_buffer_size=10M
- table_open_cache=2000
- # Remove leading
- # to turn on a very important data integrity option: logging
- # changes to the binary log between backups.
- #lob_bin
- log_bin=ON
- log_bin_basename=/var/lib/mysql/mysqld-bin
- #
- # Remove leading # to set options mainly useful for reporting servers.
- # The server defaults are faster for transactions and fast SELECTs.
- # Adjust sizes as needed, experiment to find the optimal values.
- join_buffer_size = 128M
- sort_buffer_size = 2M
- read_rnd_buffer_size = 2M
- datadir=/var/lib/mysql
- socket=/var/lib/mysql/mysql.sock
- character_set_server=utf8

如果上述檔案配置好後,執行mysql登入,丟擲xxxx.line 這樣的異常,就去/usr/share/mysql 下面複製一個.cnf檔案的頭部替換掉上述my.cnf的頭部程式碼,前提是要copy一個到/etc下,命名my.cnf,再把上面的copy,版本資訊和一些詳細檔案的
具體路徑配置,和引數配置看你自己的安裝情況
我替換的是/usr/share/mysql/my-default.cnf 標頭檔案的這幾句:
- # For advice on how to change settings please see
- # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
- # *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
- # *** default location during install, and will be replaced if you
- # *** upgrade to a newer version of MySQL.
- [mysqld]
然後[mysqlld]以下的全部是copy上面的,從上面配置檔案的第7行的#號開始,可以解決類似Fatal error in defaults handling. Program aborted 或者xxxx line xxxx 錯誤的問題,根據你伺服器的具體情況具體分析,我的是以我配置的為基準的
配置完之後,mysql可以正常登入,檢視和啟動日誌:
- mysql> show variables like 'log_%';
- +----------------------------------------+------------------------------------+
- | Variable_name | Value |
- +----------------------------------------+------------------------------------+
- | log_bin | OFF |
- | log_bin_basename | |
- | log_bin_index | |
- | log_bin_trust_function_creators | OFF |
- | log_bin_use_v1_row_events | OFF |
- | log_error | /var/lib/mysql/AY140615022008Z.err |
- | log_output | FILE |
- | log_queries_not_using_indexes | OFF |
- | log_slave_updates | OFF |
- | log_throttle_queries_not_using_indexes | 0 |
- | log_warnings | 1 |
- +----------------------------------------+------------------------------------+
- 11 rows in set (0.01 sec)
- mysql> show variables like 'log_bin';
- +---------------+-------+
- | Variable_name | Value |
- +---------------+-------+
- | log_bin | OFF |
- +---------------+-------+
- 1 row in set (0.00 sec)
- mysql> select version();
- +-----------+
- | version() |
- +-----------+
- | 5.6.10 |
- +-----------+
- 1 row in set (0.02 sec)
需要開啟的可以自己設定,希望可以幫到大家,少走歪路!
