Seata部署文档

准本文件；
准备nacos、seata-server-1.4.2.tar

一、下载seata

1、下载seata
http://seata.io/zh-cn/blog/download.html
选择binary类型的点击下载即可

2、nacos命名空间seata

二、上传至服务器

上传seata到linux服务器的 usr/local目录下

三、解压

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

四、添加log文件

添加log文件
在根目录创建logs文件夹，里面创建一个seata_gc.log的文件，结构如下图（xshell右键新建文件，再重命名即可创建）

五、初始化数据库

5.1初始化数据库

·数据库名为seata；
·branch_table表
CREATE TABLE branch_table (
branch_id bigint(20) NOT NULL,
xid varchar(128) NOT NULL,
transaction_id bigint(20) DEFAULT NULL,
resource_group_id varchar(32) DEFAULT NULL,
resource_id varchar(256) DEFAULT NULL,
branch_type varchar(8) DEFAULT NULL,
status tinyint(4) DEFAULT NULL,
client_id varchar(64) DEFAULT NULL,
application_data varchar(2000) DEFAULT NULL,
gmt_create datetime(6) DEFAULT NULL,
gmt_modified datetime(6) DEFAULT NULL,PRIMARY KEY (branch_id),KEY idx_xid (xid)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

·global_table表
CREATE TABLE global_table (
xid varchar(128) NOT NULL,
transaction_id bigint(20) DEFAULT NULL,
status tinyint(4) NOT NULL,
application_id varchar(32) DEFAULT NULL,
transaction_service_group varchar(32) DEFAULT NULL,
transaction_name varchar(128) DEFAULT NULL,
timeout int(11) DEFAULT NULL,
begin_time bigint(20) DEFAULT NULL,
application_data varchar(2000) DEFAULT NULL,
gmt_create datetime DEFAULT NULL,
gmt_modified datetime DEFAULT NULL,PRIMARY KEY (xid),KEY idx_gmt_modified_status (gmt_modified,status),KEY idx_transaction_id (transaction_id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

·lock_table表
CREATE TABLE lock_table (
row_key varchar(128) NOT NULL,
xid varchar(96) DEFAULT NULL,
transaction_id bigint(20) DEFAULT NULL,
branch_id bigint(20) NOT NULL,
resource_id varchar(256) DEFAULT NULL,
table_name varchar(32) DEFAULT NULL,
pk varchar(36) DEFAULT NULL,
gmt_create datetime DEFAULT NULL,
gmt_modified datetime DEFAULT NULL,PRIMARY KEY (row_key),KEY idx_branch_id (branch_id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

5.2业务库表

·seata需要在每个业务库添加一张undo_log表
·undo_log
CREATE TABLE undo_log (
branch_id bigint(20) NOT NULL COMMENT ‘branch transaction id’,
xid varchar(100) NOT NULL COMMENT ‘global transaction id’,
context varchar(128) NOT NULL COMMENT ‘undo_log context,such as serialization’,
rollback_info longblob NOT NULL COMMENT ‘rollback info’,
log_status int(11) NOT NULL COMMENT ‘0:normal status,1:defense status’,
log_created datetime(6) NOT NULL COMMENT ‘create datetime’,
log_modified datetime(6) NOT NULL COMMENT ‘modify datetime’,UNIQUE KEY ux_undo_log (xid,branch_id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT=‘AT transaction mode undo table’;

六、修改配置文件file.conf/registry.conf文件

6.1修改file.conf文件

只需要修改模式为db和数据库链接信息即可，如下图：

修改内容:
store.mode = db;
store.db.url = jdbc:mysql://ip:port/seata;
store.db.user = 账号
store.db.password = 密码

6.2修改registry.conf文件

只需要修改注册类型和配置类型均为nacos和nacos的相关信息即可

修改内容:
·registry.type = nacos
·registry.nacos.application = seata-server, 默认服务端的名称
·registry.nacos.serverAddr = nacos服务器的8848端口地址
·registry.nacos.group = SEATA_GROUP, 默认seata的组
·registry.nacos.namespace = seata, 默认seata的配置在nacos的命名空间
·registry.nacos.cluster = default, 采取默认集群即可
·registry.nacos.username = nacos的用户名
·registry.nacos.password = naocs的密码
·config.type = nacos
·config.nacos.namespace = seata, 默认seata的配置在nacos的命名空间
·config.nacos.group = SEATA_GROUP, 默认seata的组
·config.nacos.username = nacos的用户名
·config.nacos.password = naocs的密码

七、创建context.txt文件

context.txt文件内容
在/seata根目录下创建context.txt文件，内容如下：

·store.db.url=jdbc:mysql://IP:PORT/seata?useUnicode=true&rewriteBatchedStatements=true
·store.db.user=root
·store.db.password=123456

八、添加nacos-config.sh文件

在seata/conf目录下添加nacos-config.sh文件，内容如下：

#!/bin/sh

while getopts ":h:p:g:t:u:w:" opt
do
  case $opt in
  h)
    host=$OPTARG
    ;;
  p)
    port=$OPTARG
    ;;
  g)
    group=$OPTARG
    ;;
  t)
    tenant=$OPTARG
    ;;
  u)
    username=$OPTARG
    ;;
  w)
    password=$OPTARG
    ;;
  ?)
    echo " USAGE OPTION: $0 [-h host] [-p port] [-g group] [-t tenant] [-u username] [-w password] "
    exit 1
    ;;
  esac
done

if [ -z ${host} ]; then
    host=localhost
fi
if [ -z ${port} ]; then
    port=8848
fi
if [ -z ${group} ]; then
    group="SEATA_GROUP"
fi
if [ -z ${tenant} ]; then
    tenant=""
fi
if [ -z ${username} ]; then
    username=""
fi
if [ -z ${password} ]; then
    password=""
fi

nacosAddr=$host:$port
contentType="content-type:application/json;charset=UTF-8"

echo "set nacosAddr=$nacosAddr"
echo "set group=$group"

urlencode() {
  length="${#1}"
  i=0
  while [ $length -gt $i ]; do
    char="${1:$i:1}"
    case $char in
    [a-zA-Z0-9.~_-]) printf $char ;;
    *) printf '%%%02X' "'$char" ;;
    esac
    i=`expr $i + 1`
  done
}

failCount=0
tempLog=$(mktemp -u)
function addConfig() {
  dataId=`urlencode $1`
  content=`urlencode $2`
  curl -X POST -H "${contentType}" "http://$nacosAddr/nacos/v1/cs/configs?dataId=$dataId&group=$group&content=$content&tenant=$tenant&username=$username&password=$password" >"${tempLog}" 2>/dev/null
  if [ -z $(cat "${tempLog}") ]; then
    echo " Please check the cluster status. "
    exit 1
  fi
  if [ "$(cat "${tempLog}")" == "true" ]; then
    echo "Set $1=$2 successfully "
  else
    echo "Set $1=$2 failure "
    failCount=`expr $failCount + 1`
  fi
}

count=0
for line in $(cat $(dirname "$PWD")/context.txt | sed s/[[:space:]]//g); do
    count=`expr $count + 1`
    key=${line%%=*}
    value=${line#*=}
    addConfig "${key}" "${value}"
done

echo "========================================================================="
echo " Complete initialization parameters,  total-count:$count ,  failure-count:$failCount "
echo "========================================================================="

if [ ${failCount} -eq 0 ]; then
    echo " Init nacos config finished, please start seata-server. "
else
    echo " init nacos config fail. "
fi

注意事项：context.txt 为第七步新建的文件名

九、将contxt.txt文件内容上传至nacos

在conf文件下执行命令上传配置文件到nacos
sh nacos-config.sh -h 10.0.14.121 -p 8848 -g SEATA_GROUP -t seata -u nacos -w nacos
set nacosAddr=10.0.14.121:8848

（上面这个图错了 是 3f·····d8是我原来创建seata空间生成的随机id，后面才发现需要空间命名为seata 所以是
sh nacos-config.sh -h 10.0.14.121 -p 8848 -g SEATA_GROUP -t seata -u nacos -w nacos
set nacosAddr=10.0.14.121:8848）
注意：nacos-config.sh配置文件中 文件地址要写对

对应的是：

十、上传成功。

十一、启动seata
bin目录下：

$nohup ./seata-server.sh >log.out 2>1 &

总结

seata部署到nacos上
