本文详细介绍了如何在Kubernetes(k8s)集群上使用KubeSphere部署MySQL主从复制。首先，通过Docker实现MySQL主从复制，并强调了skip-name-resolve参数的重要性。接着，详细阐述了持久存储的准备、配置文件的创建、master和slave节点的部署，以及授权和验证过程。在配置文件中，特别提到了因MySQL 5.7默认开启SSL而需要设置skip-ssl的情况。

微服务部署前中间件部署

一、MySQL部署

1.1 使用Docker实现MySQL主从复制

docker run -p 3307:3306 --name mysql-master \
-v /mydata/mysql/master/log:/var/log/mysql \
-v /mydata/mysql/master/data:/var/lib/mysql \
-v /mydata/mysql/master/conf:/etc/mysql \
-e MySQL_ROOT_PASSWORD=root \
-d mysql:5.7

vim /mydata/mysql/master/conf/my.cnf

[client]
default-character-set=utf8

[mysql]
default-character-set=utf8

[mysqld]
init_connect='SET collation_connection = utf8_unicode_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
collation-server=utf8_unicode_ci
skip-character-set-client-handshake
skip-name-resolve

skip-name-resolve一定要加，不然连接mysql 会慢
binlog-do-db ：需要进行主从同步涉及到的业务数据库

server_id=1
log_bin=mysql-bin
read-only=0
binlog-do-db=mall_oms
binlog-do-db=mall_pms
binlog-do-db=mall_sms
binlog-do-db=mall_ums
binlog-do-db=mall_wms

replicate-ignore-db=mysql
replicate-ignore-db=sys
replicate-ignore-db=information_schema
replicate-ignore-db=performance_schema

docker run -p 3317:3306 --name mysql-slaver-01 \
-v /mydata/mysql/slaver/log:/var/log/mysql \
-v /mydata/mysql/slaver/data:/var/lib/mysql \
-v /mydata/mysql/slaver/conf:/etc/mysql \
-e MYSQL_ROOT_PASSWORD=root \
-d mysql:5.7

vim /mydata/mysql/slaver/conf/my.cnf

[client]
default-character-set=utf8

[mysql]
default-character-set=utf8

[mysqld]
init_connect='SET collation_connection = utf8_unicode_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
collation-server=utf8_unicode_ci
