Mac下MySQL配置文件是my.cnf，不是my.ini

1、Mac中配置文件是my.cnf，不是my.ini，但MySQL安装后默认没有my.cnf文件，如果想配置该文件可以参考如下内容：

1）在终端输入cd /etc，进入/etc文件夹下，然后在/etc新建my.cnf文件，使用命令：sudo vim my.cnf

2、将如下配置内容写入到文件中

[client]
default-character-set=utf8
#password   = your_password
port        = 3306
socket      = /tmp/mysql.sock
[mysqld]
character-set-server=utf8
init_connect='SET NAMES utf8
port =3306
socket = /tmp/mysql.sock

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

init_connect='SET NAMES utf8'

# 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]

max_allowed_packet = 16M
[mysql]

# Remove the next comment character if you are not familiar with SQL

[myisamchk]
key_buffer_size = 20M
sort_buffer_size = 20M
read_buffer = 2M
write_buffer = 2M

3. 保存my.cnf文件命令：":wq!"

4. 修改my.cnf的文件权限：sudo chmod 664 /etc/my.cnf

5. 重新启动mysql后，配置文件就可以生成了
