《Mysql入门mac终端下修改MySQL的编码格式--找不到my-default.cnf及my.cnf》要点： 1- 先配置环境变量path 1.1 打开终端,输入： cd ~ 会进入~文件夹, 1.2 然后输入：touch .bash_profile 回车执行后, 1.3 再输入：open -e .bash_profile 会在TextEdit中打开这个文件(如果以前没有配置过环境变量,那么这应该是一个空白文档). 如果有内容,请在结束符前输入,如果没有内容,请直接输入如下语句: export PATH=${PATH}:/usr/local/mysql/bin 然后,保存,退出TextEdit(一定是退出),关闭终端并退出. 此时应该可以直接用以下语句登入MySQL了 >mysql -uroot -p 1.4 关闭MySQL? !!!!(在系统偏好设置里面关闭MySQL) 2- 重点来了!!! 2.1 查看一下support-files文件夹(Finder下"前往文件夹";路径:/usr/local/mysql/support-files) 里面有没有my-default.cnf或my.cnf文件...如果有则直接打开添加 在[client] 在下面添加 default-character-set=utf8 默认字符集为utf8 在[mysqld] 添加 default-character-set=utf8 默认字符集为utf8 init_connect='SET NAMES utf8' (设定连接mysql数据库时使用utf8编码,以让mysql数据库为utf8运行) 修改好后,重新启动mysql查看当前数据编码格式. >show variables like '%char%'; +--------------------------+----------------------------+ | Variable_name | Value | +--------------------------+----------------------------+ | character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | utf8 | | character_set_filesystem | binary | | character_set_results | utf8 | | character_set_server | utf8 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | +--------------------------+----------------------------+ 若终端出现如上样式则OK了,否则继续往下看: 2.2 support-files文件夹里面没有my-default.cnf或my.cnf文件,那么就要在/etc下新建my.cnf $ cd /etc $ sudo vim my.cnf 2.3 进行完上步操作后会进入vim模式,此时复制(***文本)的内容粘贴进去,(不包含?? ***文本 ); 2.4 粘贴成功后注意看vim的第一行"#"有没有丢掉(本人就丢过~~哈哈~),都OK的话点esc退出编辑, :wq!???? --保存后强制退出.[附几个编辑命令:dd?? 删除光标所在行; dw?? 删除一个字(word); x?? 删除当前字符]. (***文本): # Example MySQL config file for medium systems. # # This is for a system with little memory (32M - 64M) where MySQL plays # an important part,or systems up to 128M where MySQL is used together with # other programs (such as a web server) # # MySQL programs look for option files in a set of # locations which depend on the deployment platform. # You can copy this option file to one of those # locations. For information about these locations,see: # http://dev.mysql.com/doc/mysql/en/option-files.html # # In this file,you can use all long options that a program supports. # If you want to know which options a program supports,run the program # with the "--help" option. # The following options will be passed to all MySQL clients [client] default-character-set=utf8 #password = your_password port = 3306 socket = /tmp/mysql.sock # Here follows entries for some specific programs # The MySQL server [mysqld] character-set-server=utf8 init_connect='SET NAMES utf8 port = 3306 socket = /tmp/mysql.sock skip-external-locking key_buffer_size = 16M max_allowed_packet = 1M table_open_cache = 64 sort_buffer_size = 512K net_buffer_length = 8K read_buffer_size = 256K read_rnd_buffer_size = 512K myisam_sort_buffer_size = 8M character-set-server=utf8 init_connect='SET NAMES utf8' # Don't listen on a TCP/IP port at all.

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 # Uncomment the following if you are using InnoDB tables #innodb_data_home_dir = /usr/local/mysql/data #innodb_data_file_path = ibdata1:10M:autoextend #innodb_log_group_home_dir = /usr/local/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 = 16M #innodb_additional_mem_pool_size = 2M # Set .._log_file_size to 25 % of buffer pool size #innodb_log_file_size = 5M #innodb_log_buffer_size = 8M #innodb_flush_log_at_trx_commit = 1 #innodb_lock_wait_timeout = 50 [mysqldump] quick max_allowed_packet = 16M [mysql] no-auto-rehash # Remove the next comment character if you are not familiar with SQL #safe-updates default-character-set=utf8 [myisamchk] key_buffer_size = 20M sort_buffer_size = 20M read_buffer = 2M write_buffer = 2M [mysqlhotcopy] interactive-timeout （编辑：李大同） 【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! |
