linux seata 环境部署(nacos)

首先下载seata对应版本的安装包

 地址:Seata - Browse Files at SourceForge.net    

或者/ Releases · seata/seata · GitHub

tar -zxvf seata-server-1.4.2.tar.gz 

修改registry.conf

registry {

 然后分别都授予  linux 775权限  授权命令chomd 755 XXXXX

权限说明  数字 4:读、2:写 、 1 执行

 4 + 2 + 1 = 7 (可读写运行)

755权限分为   linux seata 环境部署(nacos)_第2张图片

                      可以看出   所有者权限为7 可读写运行

                                        用户组权限为5  4+1  可读取执行

                                       公共        5       可读取执行

chomd 755 nacos-config.py

chomd 755 nacos-config.sh
然后执行 ./nacos-config.sh

 打开nacos可以看到 导入了很多seata相关的配置

 新建seata数据库然后执行以下sql

 然后新建startup.shlinux seata 环境部署(nacos)_第4张图片

 从nacos那边看已经可以正常使用了

 那试试

在我自己的工程里面可以正常使用seata了 说明已经可以完美使用了

当然你需要在自己对应的工程里面新建undo_log
