[mysqld]

# 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 = 600M #(Mysql数据缓存大小，根据自己内存大小跟需求调整)

# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin

# These are commonly set, remove the # and set as required.
 basedir = C:\Program Files\mysql57 #(Mysql目录路径)
 datadir = C:\Program Files\mysql57\data #(Mysql库路径，默认是跟根录下data文件夹，注意这个路径改了的话一定要把原data目录下的文件复制过去，不然会报1067错误)

 character-set-server=utf8 #(服务器默认字符，跟上面保持一致)
 port = 3306 #(Mysql使用端口，默认3306) 
 server_id = 11


# 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  (Join操作使用内存) 
# sort_buffer_size = 2M  (排序使用内存) 
# read_rnd_buffer_size = 2M (随机读取数据缓冲区使用内存)(以上三条根据自己的情况设置)
