Seata 1.5.1整合nacos
环境：centos7.6 docker20.0.5 nacos1.4.2 seata1.5.1 mysql5.7.34(seata1.5.1原生不支持MySQL8需要自己添加驱动，麻烦建议使用5.7，够用了)
seata在1.5版本后将配置文件改为了使用易读性更强的yaml文件（也可以继续使用以前的配置，如果你愿意开倒车的话）
我先默认已经安装好了nacos和MySQL为前提进行以下操作：
前置准备：先拉镜像启动并拷贝镜像内自带的配置文件
docker pull seata-server:1.5.1
启动seata-servcer实例，防火墙开放相应端口
docker run --name seata-server -p 8091:8091 -p 7091:7091 seataio/seata-server:1.5.1
使用自定义配置文件
自定义配置文件需要通过挂载文件的方式实现，将宿主机上的 application.yml 挂载到容器中相应的目录
首先将resources目录文件拷出的临时容器
docker cp seata-serve:/seata-server/resources /var/docker/seata/config/
此时你可以在本地看见容器内的resources目录已经完整拷贝进了宿主机目录
我们只需要改动application.yml里的配置，如何写？application.example.yml有完整的配置，直接复制过来，ip改宿主机的地址。
例如：
server:
port: 7091
spring:
application:
name: seata-server
logging:
config: classpath:logback-spring.xml
file:
path: ${user.home}/logs/seata
extend:
logstash-appender:
destination: 127.0.0.1:4560
kafka-appender:
bootstrap-servers: 127.0.0.1:9092
topic: logback_to_logstash
#这里我改了登录时默认的用户id和psw
console:

nacos:
server-addr: localhost:8848

username:
password:
##if use MSE Nacos with auth, mutex with username/password attribute
#access-key: ""
#secret-key: ""
data-id: seataServer.properties
registry:
# support: nacos, eureka, redis, zk, consul, etcd3, sofa

nacos:

password:
##if use MSE Nacos with auth, mutex with username/password attribute
#access-key: ""
#secret-key: ""
store:
# support: file 、 db 、 redis 这里选择MySQL作为存储方式，如果你需要MySQL8，那么你得自己添加驱动
mode: db
db:
datasource: druid
db-type: mysql
driver-class-name: com.mysql.jdbc.Driver

lock-table: lock_table
distributed-lock-table: distributed_lock
query-limit: 100
max-wait: 5000
# server:
# service-port: 8091 #If not configured, the default is '${server.port} + 1000'
security:
secretKey: SeataSecretKey0c382ef121d778043159209298fd40bf3850a017

urls: /,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-fe/public/**,/api/v1/auth/login
我们选择配置和注册中心都是nacos 直接将application.example.yml里关于nacos的配置复制，注意，如果你是运行在云服务器上，那么nacos和MySQL的ip应该是你的公网ip，而不是内网ip，我的云服务器用内网ip出现了无法注册的情况。
选择MySQL作为存储方式
首先给seata建表：
相较于1.4.X，1.5.X多了几张表。
官方sql链接：https://github.com/seata/seata/blob/develop/script/server/db/mysql.sql
建立seata库后，执行该sql：
-- -------------------------------- The script used when storeMode is 'db' --------------------------------
-- the table to store GlobalSession data
CREATE TABLE IF NOT EXISTS `global_table`
(
`xid` VARCHAR(128) NOT NULL,
`transaction_id` BIGINT,
`status` TINYINT NOT NULL,

`gmt_create` DATETIME,
`gmt_modified` DATETIME,
PRIMARY KEY (`xid`),

KEY `idx_transaction_id` (`transaction_id`)
) ENGINE = InnoDB
DEFAULT CHARSET = utf8mb4;
-- the table to store BranchSession data
CREATE TABLE IF NOT EXISTS `branch_table`

`branch_id` BIGINT NOT NULL,
`resource_id` VARCHAR(256),
`table_name` VARCHAR(32),
`pk` VARCHAR(36),
`status` TINYINT NOT NULL DEFAULT '0' COMMENT '0:locked ,1:rollbacking',
`gmt_create` DATETIME,

) ENGINE = InnoDB
DEFAULT CHARSET = utf8mb4;
CREATE TABLE IF NOT EXISTS `distributed_lock`
(
`lock_key` CHAR(20) NOT NULL,
`lock_value` VARCHAR(20) NOT NULL,
`expire` BIGINT,
primary key (`lock_key`)
) ENGINE = InnoDB
DEFAULT CHARSET = utf8mb4;
INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('AsyncCommitting', ' ', 0);
INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('RetryCommitting', ' ', 0);
INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('RetryRollbacking', ' ', 0);
INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('TxTimeoutCheck', ' ', 0);
还记得之前docker启动起来的seata么？他的使命已经完成，rm他，（当然你也可以把我们修改好的application.yml拷进容器再启动，如果你不怕麻烦的话），然后我们再映射好路径启动一个新的容器：
- 指定 application.yml
docker run --name seata-server
-p 8091:8091
-p 7091:7091
-v /var/docker/seata/config/resources:/seata-server/resources \
seataio/seata-server:1.5.1
进入ncaos查看是否已经注册，进入7091端口查看服务是否正常启动。
完事，yaml文件的方式易读性高了很多，docker-compose的部署方式差别不大，官网都有。
