本文主要是介绍Mysql数据库 | 基于Docker搭建Mysql-8.0以上版本主从实例实战，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
Mysql主从环境概述
Mysql集群主从环境搭建
本次采用Docker部署集群,并且首先主从实例配置。
1.Mysql-Cluster集群服务规划
2.Mysql-Cluster集群先决条件
创建 Mysql-Cluster集群主要配置目录如下：
2.1 Mysql-Master节点[3308]
创建 Mysql-Slave节点主要配置文件目录以及配置文件如下：
[1].mysql.cnf配置文件:

4.Mysql-Cluster集群Docker执行部署
4.1 Mysql-Master节点[3308]
Marklin:~ marklin$ docker run -itd -p 3308:3306 --restart always --privileged=true --name mysql-master --network-alias mysql-master --hostname mysql-master -v /docker/mysql-cluster/master/conf/my.cnf:/etc/mysql/my.cnf -v /docker/mysql-cluster/master/conf/conf.d/:/etc/mysql/conf/conf.d/ -v /docker/mysql-cluster/master/data:/var/lib/mysql -e "JAVA_OPTS=-server -Xms512m -Xmx512m -Xmn256m -Duser.home=/opt -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m -XX:+AlwaysPreTouch -XX:-UseBiasedLocking" -e TZ="Asia/Shanghai" -e MYSQL_ROOT_PASSWORD=PivotalCloud999@Love mysql:latest d99ac84d4e11dd3835b89ff410a488c8041c43ec67aa4bccb1679edf57b08539 Marklin:~ marklin$

Marklin:~ marklin$ docker run -itd -p 3309:3306 --restart always --privileged=true --name mysql-slave --network-alias mysql-slave --hostname mysql-slave -v /docker/mysql-cluster/slave/conf/my.cnf:/etc/mysql/my.cnf -v /docker/mysql-cluster/slave/conf/conf.d/:/etc/mysql/conf/conf.d/ -v /docker/mysql-cluster/slave/data:/var/lib/mysql -e "JAVA_OPTS=-server -Xms512m -Xmx512m -Xmn256m -Duser.home=/opt -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m -XX:+AlwaysPreTouch -XX:-UseBiasedLocking" -e TZ="Asia/Shanghai" -e MYSQL_ROOT_PASSWORD=PivotalCloud999@Love mysql:latest fe3eb3b02fc0cf9e187a8158b58bb5832d70a4462b583d4ba4cf4297ff7dd8d3 Marklin:~ marklin$
4.3 Mysql-Cluster集群部署以及测试结果：
Mysql-Cluster集群部署：
测试Navicat客户端连接数据如下：
5.Mysql-Cluster集群主从节点后续配置
5.1 Mysql-Cluster集群节点IP地址
1.mysql-master节点IPAddress： docker inspect --format=’{{.NetworkSettings.IPAddress}}’ mysql-master
Marklin:~ marklin$ docker inspect --format='{{.NetworkSettings.IPAddress}}' mysql-master
172.17.0.13
Marklin:~ marklin$
2.查看mysql-slave节点的IPAddress： docker inspect --format=’{{.NetworkSettings.IPAddress}}’ mysql-slave
Marklin:~ marklin$ docker inspect --format='{{.NetworkSettings.IPAddress}}' mysql-slave
172.17.0.14
Marklin:~ marklin$
5.2 Mysql-Cluster集群主从用户授权配置
进入Docker后台的两种方式：
1.通过终端输入docker ps查看容器进程，最后执行docker exec -it mysql容器名称/id bash
执行docker ps：
Marklin:~ marklin$ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES fe3eb3b02fc0 mysql:latest "docker-entrypoint.s…" 18 hours ago Up 2 hours 33060/tcp, 0.0.0.0:3309->3306/tcp mysql-slave d99ac84d4e11 mysql:latest "docker-entrypoint.s…" 18 hours ago Up 2 hours 33060/tcp, 0.0.0.0:3308->3306/tcp mysql-master 59030d0bff07 docker/dev-environments-default:stable-1 "sleep infinity" 19 hours ago Up 4 minutes mysql-cluster d0f4142d8781 dubbo-admin:latest "tini -- /usr/local/…" 13 days ago Up 2 hours 0.0.0.0:8082->8080/tcp dubbo-monitor c91f1bd81cf9 nacos-server:latest "bin/docker-startup.…" 13 days ago Up 2 hours 0.0.0.0:8848->8848/tcp nacos-server fefa57c84ee1 dubbo-admin:latest "tini -- /usr/local/…" 13 days ago Up 2 hours 0.0.0.0:8080->8080/tcp dubbo-server f3b3f54acfc3 zookeeper:latest "/docker-entrypoint.…" 13 days ago Up 2 hours 0.0.0.0:2181->2181/tcp, 0.0.0.0:2888->2888/tcp, 0.0.0.0:3888->3888/tcp, 8080/tcp zookeeper-server 1f323ef0299f mysql:5.7.36 "docker-entrypoint.s…" 5 weeks ago Up 2 hours 33060/tcp, 0.0.0.0:3307->3306/tcp mysql5.7-server a53b9713927f rabbitmq:latest "docker-entrypoint.s…" 5 weeks ago Up 2 hours 0.0.0.0:5671-5672->5671-5672/tcp, 4369/tcp, 15691-15692/tcp, 25672/tcp, 0.0.0.0:15672->15672/tcp rabbitmq-server bd7637c345b6 mysql:8.0.21 "docker-entrypoint.s…" 5 weeks ago Up 2 hours 0.0.0.0:3306->3306/tcp, 33060/tcp mysql-server 87aa352ecead redis:latest "docker-entrypoint.s…" 5 weeks ago Up 2 hours 0.0.0.0:6379->6379/tcp redis-server 6af30979d57c minio:latest "/usr/bin/docker-ent…" 5 weeks ago Up 2 hours 0.0.0.0:8081->8081/tcp, 0.0.0.0:9000->9000/tcp minio-server 51ffd8d090ba portainer-ce:latest "/portainer" 5 weeks ago Up 2 hours 8000/tcp, 9443/tcp, 0.0.0.0:9999->9000/tcp portainer-server Marklin:~ marklin$
进入mysql容器: docker exec -it d99ac84d4e11 bash
Marklin:~ marklin$ docker exec -it d99ac84d4e11 bash root@mysql-master:/#
2.通过Docker可视化后台进入：
点击Consle：
点击Conect：
进入到mysql容器：
登录mysql客户端：mysql -u root -p
root@mysql-master:/# mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 9 Server version: 8.0.27 MySQL Community Server - GPL Copyright (c) 2000, 2021, Oracle and/or its affiliates. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql>
如图所示：
创建用户并授权：
mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password by 'PivotalCloud999@Love'; Query OK, 0 rows affected (0.10 sec) mysql> ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'PivotalCloud999@Love'; Query OK, 0 rows affected (0.01 sec) mysql> CREATE USER 'slave'@'%' IDENTIFIED WITH mysql_native_password BY 'PivotalCloud999@Love'; Query OK, 0 rows affected (0.06 sec) mysql> GRANT REPLICATION SLAVE ON *.* TO 'slave'@'%'; Query OK, 0 rows affected (0.01 sec) mysql> flush privileges; Query OK, 0 rows affected (0.01 sec) mysql>
如图所示：
查看master状态：show master status; ，记录二进制文件名和位置
mysql> show variables like '%server%'; +---------------------------------+--------------------------------------+ | Variable_name | Value | +---------------------------------+--------------------------------------+ | character_set_server | utf8mb4 | | collation_server | utf8mb4_0900_ai_ci | | immediate_server_version | 999999 | | innodb_dedicated_server | OFF | | innodb_ft_server_stopword_table | | | original_server_version | 999999 | | server_id | 1 | | server_id_bits | 32 | | server_uuid | 9a675ceb-64d5-11ec-b628-0242ac11000d | +---------------------------------+--------------------------------------+ 9 rows in set (0.00 sec) mysql> show master status; +---------------+----------+--------------+------------------+-------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set | +---------------+----------+--------------+------------------+-------------------+ | binlog.000003 | 1400 | | | | +---------------+----------+--------------+------------------+-------------------+ 1 row in set (0.00 sec) mysql>
