windows版本docker安装nacos集群，使用mysql进行持久化并用nginx进行代理，整合seata进行分布式事务处理
网络准备
创建docker子网，用于网络配置
docker network create --subnet 172.18.0.0/24 nacos网络设置
| 容器名称 | ip | 本机port | 容器port |
|---|---|---|---|
| mysql | 172.18.0.2 | 3307 | 3306 |
| my-nacos1 | 172.18.0.3 | 8846 | 8848 |
| my-nacos2 | 172.18.0.4 | 8847 | 8848 |
| my-nacos3 | 172.18.0.5 | 8848 | 8848 |
| nginx | 172.18.0.6 | 1111 | 80 |
创建mysql
启动命令
docker run -di \
--name=mysql \
-p 3307:3306 \
-v E:/docker-mysql/data/mysql/conf:/etc/mysql/conf.d \
-v E:/docker-mysql/data/mysql/data:/var/lib/mysql \
-v E:/docker-mysql/data/mysql/log:/var/log/mysql \
-v E:/docker-mysql/data/mysql-files:/var/lib/mysql-files \
-e MYSQL_ROOT_PASSWORD=abc123 \
--net nacos \
--ip 172.18.0.2 \
mysql:8.0.26参数说明：
-
--name指定容器名称
-
-p将本机端口映射到容器端口，这里将本机3307映射到容器3306端口
-
-v进行挂在
-
-e指定环境变量MYSQL_ROOT_PASSWORD为abc123
-
--net指定网络
-
--ip指定容器启动的ip
-
mysql:8.0.26运行的image
navicat连接问题
成功启动后mysql，使用navicat连接，出现2059 - authentication plugin ‘caching_sha2_password‘问题
解决方案
MySQL新版本（8以上版本）的用户登录账户加密方式是【caching_sha2_password】，Navicat不支持这种用户登录账户加密方式。
#进入mysql容器中
docker exec -it mysql bash
#登陆mysql
mysql -u root -p abc123
#修改root用户加密方式
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'abc123';
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'abc123';重新连接解决问题
创建nacos数据库
CREATE DATABASE nacos根据使用的nacos版本，从官网找到对应版本的sql，这里使用1.4.1版
Release 1.4.1 (Jan 15, 2021) · alibaba/nacos (github.com)
下载windows版本并解压，从nacos/conf/中找到nacos-mysql.sql文件，在nacos数据库中运行
至此，mysql的准备工作完成！
部署nacos集群
创建三个nacos容器作为集群
#配置nacos集群
#机器1
docker run -d \
-e PREFER_HOST_MODE=hostname \
-e MODE=cluster \
-e NACOS_APPLICATION_PORT=8846 \
-e NACOS_SERVERS="172.18.0.3:8846 172.18.0.4:8847 172.18.0.5:8848" \
-e SPRING_DATASOURCE_PLATFORM=mysql \
-e MYSQL_SERVICE_HOST=172.18.0.2 \
-e MYSQL_SERVICE_PORT=3306 \
-e MYSQL_SERVICE_USER=root \
-e MYSQL_SERVICE_PASSWORD=abc123 \
-e MYSQL_SERVICE_DB_NAME=nacos \
-e NACOS_SERVER_IP=172.18.0.3 \
--net nacos \
--ip 172.18.0.3 \
--name my-nacos1 \
-p 8846:8846 \
nacos/nacos-server:1.4.1
#机器2
docker run -d \
-e PREFER_HOST_MODE=hostname \
-e MODE=cluster \
-e NACOS_APPLICATION_PORT=8847 \
-e NACOS_SERVERS="172.18.0.3:8846 172.18.0.4:8847 172.18.0.5:8848" \
-e SPRING_DATASOURCE_PLATFORM=mysql \
-e MYSQL_SERVICE_HOST=172.18.0.2 \
-e MYSQL_SERVICE_PORT=3306 \
-e MYSQL_SERVICE_USER=root \
-e MYSQL_SERVICE_PASSWORD=abc123 \
-e MYSQL_SERVICE_DB_NAME=nacos \
-e NACOS_SERVER_IP=172.18.0.4 \
--net nacos \
--ip 172.18.0.4 \
--name my-nacos2 \
-p 8847:8847 \
nacos/nacos-server:1.4.1
#机器3
docker run -d \
-e PREFER_HOST_MODE=hostname \
-e MODE=cluster \
-e NACOS_APPLICATION_PORT=8848 \
-e NACOS_SERVERS="172.18.0.3:8846 172.18.0.4:8847 172.18.0.5:8848" \
-e SPRING_DATASOURCE_PLATFORM=mysql \
-e MYSQL_SERVICE_HOST=172.18.0.2 \
-e MYSQL_SERVICE_PORT=3306 \
-e MYSQL_SERVICE_USER=root \
-e MYSQL_SERVICE_PASSWORD=abc123 \
-e MYSQL_SERVICE_DB_NAME=nacos \
-e NACOS_SERVER_IP=172.18.0.5 \
--net nacos \
--ip 172.18.0.5 \
--name my-nacos3 \
-p 8848:8848 \
nacos/nacos-server:1.4.1参数说明
-
MODE指定nacos运行模式，standalone表示单机，cluster表示以集群方式启动
-
NACOS_APPLICATION_PORT指定nacos在本机运行的端口
-
NACOS_SERVERS指定集群中有哪些机器
-
SPRING_DATASOURCE_PLATFORM指定数据源
-
MYSQL_SERVICE_HOST指定mysql的hostname
-
MYSQL_SERVICE_PORT指定mysql的端口号
-
MYSQL_SERVICE_USER指定mysql的用户名
-
MYSQL_SERVICE_PASSWORD指定mysql登陆密码
-
MYSQL_SERVICE_DB_NAME指定nacos连接的数据库
-
NACOS_SERVER_IP指定nacos的ip
-
--net指定网络
-
--ip指定ip
-
-p端口映射
启动后，查看每台机器的日志
docker logs -f my-nacos1可以看到nacos启动成功，并使用外部存储
使用本地8847访问成功，同理8846，8848端口都可以成功访问
查看集群管理，三台机器都成功启动
至此，nacos集群搭建完成
nginx代理
修改配置文件
先简单创建nginx
docker run --name mynginx -d nginx复制对应的文件到本地，修改后再拷贝至容器内
# 复制mynginx容器中的静态文件
docker cp mynginx:/usr/share/nginx/html E:/nginx/html
# 复制mynginx容器中的配置文件
docker cp mynginx:/etc/nginx/nginx.conf E:/nginx/conf/nginx.conf
# 复制mynginx容器中的默认配置文件
docker cp mynginx:/etc/nginx/conf.d/default.conf E:/nginx/conf.d/default.conf
修改配置文件
修改/e/nginx/conf.d/default.conf
upstream nacosserver {
server 172.18.0.3:8846;
server 172.18.0.4:8847;
server 172.18.0.5:8848;
}
server {
listen 80;
listen [::]:80;
server_name localhost;
#access_log /var/log/nginx/host.access.log main;
location / {
#root /usr/share/nginx/html;
#index index.html index.htm;
proxy_pass http://nacosserver;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ {
# root html;
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}关闭并删除刚刚创建的mynginx
重新创建nginx
创建nginx进行代理
docker run -it -d \
--name nginx \
--restart=on-failure:5 \
-p 1111:80 \
-v E:/nginx/html:/usr/share/nginx/html \
-v E:/nginx/conf/nginx.conf:/etc/nginx/nginx.conf \
-v E:/nginx/conf.d/default.conf:/etc/nginx/conf.d/default.conf \
-v E:/nginx/log:/var/log/nginx \
--net nacos \
--ip 172.18.0.6 \
--privileged nginx:1.21.1 效果演示
使用本地的1111端口可以对nacos进行访问。
将服务部署到nacos中
我是跟着尚硅谷的springcloud课程做的，这里贴一下yaml配置
server:
port: 9002
spring:
application:
name: nacos-payment-provider
cloud:
nacos:
discovery:
server-addr: localhost:1111
# server-addr: localhost:8848 #配置Nacos地址
management:
endpoints:
web:
exposure:
include: '*'项目成功启动无报错
查看网页，服务成功注册
至此，docker下搭建nacos集群使用mysql进行持久化，使用nginx进行代理全部完成
seata部署

需要在mysql中创建seata数据库，同时在源码中找到sql文件进行运行，这里是1.4.2版本的sql文件

运行服务，将seata整合进业务中

username: root
password: abc123
feign:
hystrix:
enabled: false
logging:
level:
io:
seata: info
mybatis:
mapperLocations: classpath:mapper/*.xml最后，每个业务的resouce文件下放上前面写好的registry.conf
seata的使用需要在业务的服务实现类上加上注解@GlobalTransactional，当出现异常时就能实现所有数据库的回滚
最后启动每个业务没有报错，在nacos集群上就能看到每个都注册成功了
正常的功能调用
事务回滚，AccountServiceImpl加上超时，进行测试，首先调用失败
再查看seata_order数据库，没有状态为0的订单记录，事务回滚，测试成功
至此，windows+docker+mysql+nacos+nginx+seata全部成功！！！
后话
为什么要使用docker呢，本地的内存只有16g全部使用虚拟机的话，nacos集群、nginx、sentinel这些肯定没有办法全部开启，所以使用docker能很好地解决这些问题。同时，以后工作的话也是需要使用docker的，因此这里选择全部使用docker进行部署，熟悉这一套流程，提升了能力。
