一、部署实例

1.下载2个软件

http://ftp.kaist.ac.kr/mysql/Downloads/MySQL-5.7/mysql-5.7.35-winx64.ziphttp://ftp.kaist.ac.kr/mysql/Downloads/MySQL-8.0/mysql-8.0.26-winx64.zip

2.解压一下

3.初始化

• 记录下密码

C:\Users\Administrator>D:\test\mysql-5.7.35-winx64\bin\mysqld --initialize --console2022-01-20T03:37:59.769162Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).2022-01-20T03:38:03.808644Z 0 [Warning] InnoDB: New log files created, LSN=457902022-01-20T03:38:03.901775Z 0 [Warning] InnoDB: Creating foreign key constraint system tables.2022-01-20T03:38:04.079914Z 0 [Warning] No existing UUID has been found, so we assume that this is the first time that this server has been started. Generating a new UUID: 5fd0428e-79a2-11ec-b336-00155d9ebf27.2022-01-20T03:38:04.092275Z 0 [Warning] Gtid table is not ready to be used. Table 'mysql.gtid_executed' cannot be opened.2022-01-20T03:38:05.824394Z 0 [Warning] A deprecated TLS version TLSv1 is enabled. Please use TLSv1.2 or higher.2022-01-20T03:38:05.824844Z 0 [Warning] A deprecated TLS version TLSv1.1 is enabled. Please use TLSv1.2 or higher.2022-01-20T03:38:05.826505Z 0 [Warning] CA certificate ca.pem is self signed.2022-01-20T03:38:07.018691Z 1 [Note] A temporary password is generated for root@localhost: pE.Yu96:XQEp

• 初始化数据如下图，默认是在安装程序的data目录下面
• 把初始化的数据拷贝到自定义的数据目录。
• 添加下my.ini配置

[mysqld]port=3306character_set_server=utf8basedir=D:/test/mysql-5.7.35-winx64datadir=D:/test/data3306server-id=1sql_mode=NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTIONlower_case_table_names=1innodb_file_per_table = 1log_timestamps=SYSTEMlog-error = error.logslow_query_log = 1slow_query_log_file = slow.loglong_query_time = 5log-bin = binlogbinlog_format = rowexpire_logs_days = 15log_bin_trust_function_creators = 1[client]   default-character-set=utf8

4.安装服务

C:\Users\Administrator>D:\test\mysql-5.7.35-winx64\bin\mysqld --install mysql3306 --defaults-file=D:\test\data3306\my.iniService successfully installed.

5.开启

C:\Users\Administrator>net start mysql3306mysql3306 服务正在启动 .mysql3306 服务已经启动成功。

-----------------以上安装了一个3306，依葫芦画瓢再安装一个3307---------------------

D:\test\mysql-5.7.35-winx64\bin\mysqld --initialize --console2022-01-20T05:38:55.054718Z 1 [Note] A temporary password is generated for root@localhost: E)+H2UUpeJRfD:\test\mysql-5.7.35-winx64\bin\mysqld --install mysql3307 --defaults-file=D:\test\data3307\my.inimysql3307 服务正在启动 .mysql3307 服务已经启动成功。

• 查看服务信息

6.修改密码

C:\Users\Administrator>cd /d d:\test\mysql-5.7.35-winx64\bind:\test\mysql-5.7.35-winx64\bin>mysql -uroot -ppE.Yu96:XQEpmysql: [Warning] Using a password on the command line interface can be insecure.Welcome to the MySQL monitor.  Commands end with ; or \g.Your MySQL connection id is 2Server version: 5.7.35-logCopyright (c) 2000, 2021, Oracle and/or its affiliates.Oracle is a registered trademark of Oracle Corporation and/or itsaffiliates. Other names may be trademarks of their respectiveowners.Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'GreatSQL';Query OK, 0 rows affected (0.01 sec)mysql> flush privileges;Query OK, 0 rows affected (0.01 sec)# 然后重新登陆一下d:\test\mysql-5.7.35-winx64\bin>mysql -uroot -p"GreatSQL" -P3307

二、建立主从

1.主节点建表等

mysql> create table t1(id int(1) not null auto_increment , name varchar(64),primary key(id));Query OK, 0 rows affected (0.06 sec)mysql> insert into t1 values(1,'GreatSQL');Query OK, 1 row affected (0.01 sec)

2.迁移数据

d:\test\mysql-5.7.35-winx64\bin>mysqldump.exe -uroot -pGreatSQL -P3306 --single-transaction --master_data=2 --set-gtid-purged=OFF --databases test > d:\test.sqlmysqldump: [Warning] Using a password on the command line interface can be insecure.d:\test\mysql-5.7.35-winx64\bin>mysql -uroot -pGreatSQL -P3307 < d:\test.sqlmysql: [Warning] Using a password on the command line interface can be insecure.

3.主节点赋权

CREATE USER `sync`@`127.0.0.1` IDENTIFIED BY 'sync';GRANT Replication Slave ON *.* TO `sync`@`127.0.0.1`;flush privileges;

4.看下dump文件的pos值

d:\test\mysql-5.7.35-winx64\bin>more d:\test.sql-- MySQL dump 10.13  Distrib 5.7.35, for Win64 (x86_64)......-- Current Database: `test`-- CHANGE MASTER TO MASTER_LOG_FILE='binlog.000002', MASTER_LOG_POS=1350;

5.从节点建立同步

change master to master_host="127.0.0.1",master_port=3306,MASTER_USER='sync',MASTER_PASSWORD='sync',MASTER_LOG_FILE='binlog.000002', MASTER_LOG_POS=1350;start slave; 

6.完成同步

mysql> show slave status\G;*************************** 1. row ***************************               Slave_IO_State: Waiting for master to send event                  Master_Host: 127.0.0.1                  Master_User: sync                  Master_Port: 3306                Connect_Retry: 60              Master_Log_File: binlog.000002          Read_Master_Log_Pos: 1959               Relay_Log_File: YOS-DAAJTV9J5RF-relay-bin.000003                Relay_Log_Pos: 926        Relay_Master_Log_File: binlog.000002             Slave_IO_Running: Yes            Slave_SQL_Running: Yes              Replicate_Do_DB:          Replicate_Ignore_DB:           Replicate_Do_Table:       Replicate_Ignore_Table:      Replicate_Wild_Do_Table:  Replicate_Wild_Ignore_Table:                   Last_Errno: 0                   Last_Error:                 Skip_Counter: 0          Exec_Master_Log_Pos: 1959              Relay_Log_Space: 1143              Until_Condition: None               Until_Log_File:                Until_Log_Pos: 0           Master_SSL_Allowed: No           Master_SSL_CA_File:           Master_SSL_CA_Path:              Master_SSL_Cert:            Master_SSL_Cipher:               Master_SSL_Key:        Seconds_Behind_Master: 0Master_SSL_Verify_Server_Cert: No                Last_IO_Errno: 0                Last_IO_Error:               Last_SQL_Errno: 0               Last_SQL_Error:  Replicate_Ignore_Server_Ids:             Master_Server_Id: 1                  Master_UUID: 5fd0428e-79a2-11ec-b336-00155d9ebf27             Master_Info_File: D:\test\data3307\master.info                    SQL_Delay: 0          SQL_Remaining_Delay: NULL      Slave_SQL_Running_State: Slave has read all relay log; waiting for more updates           Master_Retry_Count: 86400                  Master_Bind:      Last_IO_Error_Timestamp:     Last_SQL_Error_Timestamp:               Master_SSL_Crl:           Master_SSL_Crlpath:           Retrieved_Gtid_Set:            Executed_Gtid_Set:                Auto_Position: 0         Replicate_Rewrite_DB:                 Channel_Name:           Master_TLS_Version:1 row in set (0.00 sec)ERROR:No query specified

三、升级8.0

1.部署mysql8

d:\test\mysql-5.7.35-winx64\bin>D:\test\mysql-8.0.26-winx64\bin\mysqld --installmysql8_3307 --defaults-file=D:\test\data3306\my.iniService successfully installed.

2.停掉原来的

d:\test\mysql-5.7.35-winx64\bin>net stop mysql3307mysql3307 服务正在停止.mysql3307 服务已成功停止。

3.修改下配置

[mysqld]port=3307character_set_server=utf8basedir=D:/test/mysql-8.0.26-winx64  #路径改了datadir=D:/test/data3307   server-id=2sql_mode=NO_ENGINE_SUBSTITUTION #sql_mode 改了lower_case_table_names=1innodb_file_per_table = 1log_timestamps=SYSTEMlog-error = error.logslow_query_log = 1slow_query_log_file = slow.loglong_query_time = 5log-bin = binlogbinlog_format = rowexpire_logs_days = 15log_bin_trust_function_creators = 1[client]   default-character-set=utf8

4.开启服务，会自动升级

net start mysql8_3307

5.查看日志升级成功了

2022-01-20T17:33:33.598491+08:00 2 [System] [MY-011003] [Server] Finished populating Data Dictionary tables with data.2022-01-20T17:33:37.652733+08:00 5 [System] [MY-013381] [Server] Server upgrade from '50700' to '80026' started.2022-01-20T17:33:53.602051+08:00 5 [System] [MY-013381] [Server] Server upgrade from '50700' to '80026' completed.
