mysql 同一服务器同步_MySQL 同一台服务器同步数据

布满荆棘的人生 2023-10-05 18:44 13阅读 0赞

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

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:\\ProgramData\\MySQL\\MySQL Server 5.7

datadir=C:\\ProgramData\\MySQL\\MySQL Server 5.7\\data

sql\_mode=NO\_ENGINE\_SUBSTITUTION,STRICT\_TRANS\_TABLES

\[WinMySQLAdmin\]

C:\\Program Files\\MySQL\\MySQL Server 5.7\\bin\\mysqld.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

\# \*\*\* default location during install, and will be replaced if you

\# \*\*\* upgrade to a newer version of MySQL.

\# 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.

\# 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

\[mysqld\]

\#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:\\ProgramData\\MySQL1\\MySQL Server 5.7

datadir=C:\\ProgramData\\MySQL1\\MySQL Server 5.7\\data

sql\_mode=NO\_ENGINE\_SUBSTITUTION,STRICT\_TRANS\_TABLES

\[WinMySQLAdmin\]

C:\\Program Files\\MySQL1\\MySQL Server 5.7\\bin\\mysqld.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 Files\\MySQL\\MySQL Server 5.7\\bin

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
