使用docker运行seata-server:1.0.0
本文档使用docker容器运行seata-server:1.0.0版本，并以nacos作为注册中心与配置中心，使用mysql作为seata数据库
1.1 docker 拉取seata-server:1.0.0镜像
1 docker pull seataio/seata-server:1.0.0
1.2 查看镜像是否拉取成功
1 docker image ls
1.3 docker启动seata-server
1 docker run --name seata-server -p 8091:8091 -e SEATA_IP=192.168.0.177 -e SEATA_PORT=8091 -d seataio/seata-server:1.0.0
1.4 将nacos-config导入到nacos配置中心，需要注意的是seata-server:1.0.0的容器中并没有关于nacos的配置文件，所以这里在github中将对应的配置下载下来供大家使用。
nacos-config.sh：将以下内容保存至sh文件，使用该sh文件将txt中的配置推向nacos配置中心
1 #!/usr/bin/env bash 2 if [ $# != 1 ]; then 3 echo "./nacos-config.sh nacosIp" 4 exit -1 5 fi 6 nacosIp=$1 7 echo "set nacosIp=$nacosIp" 8 error=0 9 for line in $(cat nacos-config.txt) 10 do 11 key=${line%%=*} 12 value=${line#*=} 13 echo "\r\n set "${key}" = "${value} 14 result=`curl -X POST "http://$nacosIp:8848/nacos/v1/cs/configs?dataId=$key&group=SEATA_GROUP&content=$value"` 15 if [ "$result"x == "true"x ]; then 16 echo "\033[42;37m $result \033[0m" 17 else 18 echo "\033[41;37 $result \033[0m" 19 let error++ 20 fi 21 done 22 if [ $error -eq 0 ]; then 23 echo "\r\n\033[42;37m init nacos config finished, please start seata-server. \033[0m" 24 else 25 echo "\r\n\033[41;33m init nacos config fail. \033[0m" 26 fi
nacos-config.txt：seata的配置，这里已经将对应的数据库配置修改掉了，如果配置有变的话只需要修改对应的配置项就可以，配置项默认被推到public命名空间，后续只需要将这些配置克隆到自己的命名空间就可以了

将这两个文件拿到服务器中，然后执行下面的命令，就可以将配置推到nacos
1 sh nacos-config.sh 192.168.0.1772 ### 192.168.0.177 为nacos的服务器地址
1.5 进入seata-server容器
1 docker exec -ti seata-server sh
1.6 修改seata的配置
1 vi resources/registry.conf
将文件改为如下内容
1 registry { 2 type = "nacos" 3 nacos { 4 serverAddr = "192.168.0.177:8848" 5 namespace = "e02de5de-d737-45d5-af22-ae87d0137308" 6 cluster = "default" 7 } 8 } 9 config { 10 type = "nacos" 11 nacos { 12 serverAddr = "192.168.0.177:8848" 13 namespace = "e02de5de-d737-45d5-af22-ae87d0137308" 14 group = "SEATA_GROUP" 15 } 16 }
1.7 重启seata-server容器
1 docker restart seata-server
1.8 在seata配置的数据库中数据库执行以下SQL语句，创建seata所需要的表
1 -- the table to store GlobalSession data 2 drop table if exists `global_table`; 3 create table `global_table` ( 4 `xid` varchar(128) not null, 5 `transaction_id` bigint, 6 `status` tinyint not null, 7 `application_id` varchar(32), 8 `transaction_service_group` varchar(32), 9 `transaction_name` varchar(64), 10 `timeout` int, 11 `begin_time` bigint, 12 `application_data` varchar(2000), 13 `gmt_create` datetime, 14 `gmt_modified` datetime, 15 primary key (`xid`), 16 key `idx_gmt_modified_status` (`gmt_modified`, `status`), 17 key `idx_transaction_id` (`transaction_id`) 18 ); 19 20 -- the table to store BranchSession data 21 drop table if exists `branch_table`; 22 create table `branch_table` ( 23 `branch_id` bigint not null, 24 `xid` varchar(128) not null, 25 `transaction_id` bigint , 26 `resource_group_id` varchar(32), 27 `resource_id` varchar(256) , 28 `lock_key` varchar(128) , 29 `branch_type` varchar(8) , 30 `status` tinyint, 31 `client_id` varchar(64), 32 `application_data` varchar(2000), 33 `gmt_create` datetime, 34 `gmt_modified` datetime, 35 primary key (`branch_id`), 36 key `idx_xid` (`xid`) 37 ); 38 39 -- the table to store lock data 40 drop table if exists `lock_table`; 41 create table `lock_table` ( 42 `row_key` varchar(128) not null, 43 `xid` varchar(96), 44 `transaction_id` long , 45 `branch_id` long, 46 `resource_id` varchar(256) , 47 `table_name` varchar(32) , 48 `pk` varchar(32) , 49 `gmt_create` datetime , 50 `gmt_modified` datetime, 51 primary key(`row_key`) 52 );
