声明：我配置出来的slave_io_running和slave_sql_running都是yes。但是数据并没有同步！
希望有遇到相同问题的朋友，能够告诉我一下解决方案？
首先，如何在同一个服务器安装两个MySQL
https://blog.csdn.net/hanjun0612/article/details/81236694
接着我们配置两个mysql同步数据
一 先看mysql1的my.ini
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/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]
# 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 = .....
# datadir = .....
# port = .....
# 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 = 2M
# read_rnd_buffer_size = 2M
# 以下内容手动添加
[client]
port=3307
default-character-set=utf8
[mysqld]
#skip-grant-tables
#从库配置
server_id=1
#需要同步的表，不写则默认整个库同步
binlog-do-db=testdb
slave_parallel_type='logical_clock'
slave_parallel_workers=4
log_bin=mysql-bin
log_bin-index=mysql-bin.index
#端口
port=3306
character_set_server=utf8
#我的data和bin目录分成了连个，所以路径有些不一样，大家按照自己的来就行
#解压目录
basedir=C:ProgramDataMySQLMySQL Server 5.7
#解压目录下data目录
datadir=C:ProgramDataMySQLMySQL Server 5.7data
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
[WinMySQLAdmin]
C:Program FilesMySQLMySQL Server 5.7inmysqld.exe二 在看mysql2的my.ini
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the

# 以下内容手动添加
[client]
port=3307

[mysqld]
#从库配置
server_id=2
#这个是你需要覆盖的库
replicate-do-db=kps_common
relay-log-index=slave-relay-bin.index
relay-log=slave-relay-bin
#端口
port=3307
character_set_server=utf8
#我的data和bin目录分成了连个，所以路径有些不一样，大家按照自己的来就行
#解压目录
basedir=C:ProgramDataMySQL1MySQL Server 5.7
#解压目录下data目录
datadir=C:ProgramDataMySQL1MySQL Server 5.7data
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
[WinMySQLAdmin]
C:Program FilesMySQL1MySQL Server 5.7inmysqld.exe三 命令配置mysql1
接着，先配置mysql1
打开cmd，然后转到mysql1的bin目录
1 cd
2 cd C:Program FilesMySQLMySQL Server 5.7in
3 输入 mysql -uroot -p
4 输入密码 登录成功
5 show master status;
第5步，完成后，出现下图：（图片是拷贝的，主要记住File和Position）
最后使用语句
PS：这里必须要填192.168.1.88的ip，而不是127.0.0.1。不然之后会Slave_IO_Running:Connecting
这个问题困扰了我2天，后来偶然的使用ip来赋值用户权限，才正确！
create user slave;
grant replication slave on *.* to 'slave'@'192.168.1.88'identified by '123';
flush privileges;四 命令配置mysql2
同上面一样，先打开cmd，然后转到mysql2的bin目录
然后登陆。
接着运行
CHANGE MASTER TO
master_host = '192.168.1.88',
master_user = 'slave',
master_password = '123',
master_log_file = 'bin_log.000002',
master_log_pos = 631; 然后运行
start slave;
show slave status G;出现这个就正确了
