mysql 修改端口
1. 停止mysql服务
2. 打开文件夹下my.ini文件。（E:mysql-5.7-3307）
修改文件中的port值，注意两个地方：
[client]
default-character-set = utf8mb4
port = 3307
[mysqld]
basedir = E:mysql-5.7-3307
datadir = E:mysql-5.7-3307data
port = 3307
# 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.
[client]
default-character-set = utf8mb4
port = 3307
[mysql]
default-character-set = utf8mb4
[mysqld]
character-set-client-handshake = FALSE
character-set-server = utf8mb4
collation-server = utf8mb4_bin
init_connect='SET NAMES utf8mb4'
# 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 = 128M
# 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 = E:mysql-5.7-3307
datadir = E:mysql-5.7-3307data
port = 3307
# master服务唯一标识
server_id = 2
# 二进制同步数据文件
log-bin = E:mysql-5.7-3307mysql-bin
binlog-do-db = db1
# binlog-do-db和binlog-ignore-db只需指定一个
# binlog-ignore-db=mysql
# server_id = .....
# 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 = 16M
read_rnd_buffer_size = 16M
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
3. 启动服务。（如修改失败，可重新绑定 my.ini文件后，重启服务）
