docker 运行 seata-server 配置nacos
拉取镜像
docker pull seataio/seata-server
运行镜像
docker run --name seata-server -p 8091:8091 -d seataio/seata-server
获取配置文件
docker cp seata-server:/seata-server /opt/seata/
停止并删除服务
docker stop seata-server
docker rm seata-server
启动seata
docker run -d --restart always --name seata-server -p 8091:8091 -e SEATA_IP=192.168.56.102 -v /opt/seata/seata-server:/seata-server seataio/seata-server
SEATA_IP为宿主机的ip, 用于seata向nacos注册服务的ip
进入seata配置目录
cd /opt/seata/seata-server/resources
修改配置文件
修改registry.conf
registry {
# 修改type 改为nacos
type = "nacos"
# 修改nacos的配置
nacos {
application = "seata-server"
serverAddr = "192.168.56.102:8848"
group = "SEATA_GROUP"
namespace = "efc565c4-9bba-46b0-b2d5-9e2f9bd75c01"
cluster = "default"
username = "nacos"
password = "nacos"
}
...
config {
# 修改为nacos
type = "nacos"
# 修改nacos的配置
nacos {
serverAddr = "192.168.56.102:8848"
namespace = "efc565c4-9bba-46b0-b2d5-9e2f9bd75c01"
group = "SEATA_GROUP"
username = "nacos"
password = "nacos"
}
}
重新启动nacos
docker restart seata-server
注意:
这样运行会出现一个错误, 我们查看日志: docker logs seata-server, 但是我们在docker可以ping通宿主机
java.lang.RuntimeException: ErrCode:500, ErrMsg:failed to req API:/nacos/v1/ns/instance after all servers([192.168.56.102:8848]) tried: java.net.NoRouteToHostException: No route to host (Host unreachable)

错误解决方案: docker访问宿主机：No route to host (Host unreachable)
- 解决No route to host (Host unreachable)
测试可用
firewall-cmd --zone=public --add-port=8848/tcp --permanent
firewall-cmd --reload
这边的ip明显是不对的, 这个ip是docker容器ip, 我们已经做了宿主机和docker容器端口映射, 我们需要把宿主机的ip让seat-server去注册
我们需要在添加一个参数: -e SEATA_IP=192.168.56.102
(前面脚本已经修改,应不会出现此问题了)
docker run -d --restart always --name seata-server -p 8091:8091 -e SEATA_IP=192.168.56.102 -v /opt/seata/seata-server:/seata-server seataio/seata-server
删掉seata-server容器,重新运行脚本
配置mysql
- 新建库
seata
- 新建表
at模式, 这张表客户端用的, 不建表不影响启动。

- seata的版本?
2020年10月21日的最新版, 为1.3.0之后的一个版本
