Linux 下没有 my.cnf 文件的解决方式，完全是我自己整的，好多教程都是瞎扯的
我看过好多关于Linux下没有my.cnf的博客，都是什么rmp安装没有my.cnf文件啊，然后什么两个方法啊，我就无语了，大家要是知道就不会查资料了，你们敢不敢负责点？说详细点？有的说从 /usr/share/mysql 里复制一个.cnf文件到 /etc 下，有用吗？配置文件资料不给别人，复制个毛线？复制谁都会！
my.cnf 配置文件：
# 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, else 10%. 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 innodb_file_per_table=ON innodb_max_dirty_page_pct=50 back_log=80 interactive_timeout=3600 key_buffer_size=10M max_allow_packet=40440 max_connections=1000 max_tmp_tables=60 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 #init_connect='SET NAMES utf8' # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 # Recommended in standard MySQL setup sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES #general_log general_log=ON general_log_file=/var/lib/mysql/localhost.log #slow_query_log slow_query_log=ON slow_query_log_file=/var/lib/mysql/localhost-slow.log slow_launch_time=2 [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid
如果上述文件配置好后，执行mysql登录，抛出xxxx.line 这样的异常，就去/usr/share/mysql 下面复制一个.cnf文件的头部替换掉上述my.cnf的头部代码，前提是要copy一个到/etc下，命名my.cnf，再把上面的copy，版本信息和一些详细文件的
具体路径配置，和参数配置看你自己的安装情况
我替换的是/usr/share/mysql/my-default.cnf 头文件的这几句：
# 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]
然后[mysqlld]以下的全部是copy上面的，从上面配置文件的第7行的#号开始，可以解决类似Fatal error in defaults handling. Program aborted 或者xxxx line xxxx 错误的问题，根据你服务器的具体情况具体分析，我的是以我配置的为基准的
配置完之后，mysql可以正常登录，查看和启动日志：
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)
需要开启的可以自己设置，希望可以帮到大家，少走歪路！
