本文档详细介绍了如何在Docker环境下部署Seata1.4.0，包括启动Zookeeper，创建Seata所需数据库表，下载Seata镜像，配置并启动Seata服务器，以及使用Zookeeper初始化Seata配置。涉及到的组件包括Zookeeper、MySQL、Seata和Docker。

部署环境：

Seata版本1.4.0
docker
mysql 5.7
注册中心：zookeeper

说明：其他注册中心的配置步骤一样，只是配置文件内容个别改变

参考：

官方部署手册
https://linewell.yuque.com/oill7w/newbie/bkgkq0
https://seata.io/zh-cn/docs/ops/deploy-by-docker-142.html

标题部署步骤：

1、先启动zookeeper

docker run -d -p 2181:2181 \
-v /home/docker/zookeeper/data:/data \
-v /home/docker/zookeeper/logs:/logs \
-v /home/docker/zookeeper/datalog:/datalog \
--name zookeeper \
--restart=always \
zookeeper:latest

2、Seata镜像下载

docker pull seataio/seata-server:1.4.0

3、数据库新建seata相关表

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

SET FOREIGN_KEY_CHECKS = 1;

4、运行seata

（1）不配置启动seata

docker run -d --name seata-server -p 8091:8091 seataio/seata-server:1.4.0

（2）将配置文件拷贝出来：

docker cp seata-server:/seata-server/resources /home/docker/seata/config/

（3）编辑配置文件file.conf和registry.conf

	# 切换到外部文件夹下
	cd /home/docker/seata/config/resources
	
	# 配置 file.conf,存储方式为db,并配置数据库，注意 driverClassName在mysql8.x是com.mysql.cj.jdbc.Driver
	vi file.conf
	
	# 保存退出	
	:wq

在这里插入图片描述

# 配置registry.conf,配置注册类型为zk,并配置zk注册中心地址
 vi registry.conf

# 保存退出
:wq

在这里插入图片描述

![在这里插入图片描述](https://img-blog.csdnimg.cn/90c18b5f587f4012a5ee6de93d3816de.png

（4）挂载配置文件重新启动seata

# 停止容器
docker stop seata-server

# 删除容器
docker rm seata-server

# 重新启动容器，这次是为了挂载外面的配置文件
docker run -d \
--name seata-server \
-p 8091:8091 \
-e SEATA_IP=192.168.8.49 \
-v /home/docker/seata/config/resources:/seata-server/resources \
seataio/seata-server:1.4.0

5、zookeeper 初始化seata

(1）配置脚本

官网下载对应版本的包，里面有各中注册中心的初始化seata脚本

https://github.com/seata/seata/releases/tag/v1.4.0

在这里插入图片描述

或者自己新建，步骤如下

# 切换到zk的/data目录下
cd /home/docker/zookeeper/data

# 配置文件config.txt
vi config.txt

# 新建zk文件夹
mkdir zk
cd zk/
# 配置脚本 vi zk-config.sh，内容如下
vi zk-config.sh

config.txt内容如下：

}

check_node "${zkAddr}" "${zkHome}"

if [[ $(cat "${tempLog}") =~ "No such file or directory" ]]; then
	echo " ZK home is error, please enter correct zk home! "
	exit 1
elif [[ $(cat "${tempLog}") =~ "Exception" ]]; then
	echo " Exception error, please check zk cluster status or if the zk address is entered correctly! "
	exit 1

	create_node "${zkAddr}" "${zkHome}"
else
	read -p "${root} node already exists, now delete ${root} node in zk, y/n: " result
	if [[ ${result} == "y" ]]; then
		echo "Delete ${root} node..."
		delete_node "${zkAddr}" "${zkHome}"
		create_node "${zkAddr}" "${zkHome}"
	else
		exit 0
	fi
fi

for line in $(cat $(dirname "$PWD")/config.txt | sed s/[[:space:]]//g); do
	key=${line%%=*}
	value=${line#*=}
	echo "Set" "${key}" "=" "${value}"
	create_subNode "${zkAddr}" "${zkHome}" "${key}" "${value}"
done

（2）配置config.txt，如下图

group的配置在springboot项目中要配置，名称需要和图中 demo_tx_group保持一致
注意 driverClassName在mysql8.x是com.mysql.cj.jdbc.Driver
在这里插入图片描述

（3）在zk容器内部执行脚本

# 进入zookeeper容器
docker exec -it zookeeper bash 

# 切换到/data/zk目录下
cd /data/zk

# 修改脚本为可执行文件
chmod +x zk-config.sh
# 执行脚本
./zk-config.sh -h 192.168.206.185 -p 2181 -z /apache-zookeeper-3.7.0-bin
