• Docker安装Seata

    部署环境：

    Seata版本1.4.0
    docker
    mysql 5.7
    注册中心：zookeeper

    说明：其他配置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

    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	

    • 1

    （2）将配置文件拷贝出来：

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

    • 1

    （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

    （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

    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

    （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
