1、创建目录

mkdir -p /Seata && cd /Seata

 

2、下载并解压

wget https://archive.apache.org/dist/incubator/seata/2.2.0/apache-seata-2.2.0-incubating-bin.tar.gz
tar -xzf apache-seata-2.2.0-incubating-bin.tar.gz
cd seata-server

 

3、MySQL创建seata用户

mysql -uroot -p

-- 1. 建库
CREATE DATABASE IF NOT EXISTS seata DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;

-- 2. 建用户并授权（Seata 专用账号，不要用 root）
CREATE USER IF NOT EXISTS 'seata'@'%' IDENTIFIED BY 'seata';
GRANT ALL PRIVILEGES ON seata.* TO 'seata'@'%';
FLUSH PRIVILEGES;

 

4、导入数据

cat > seata_server.sql <<'EOF'

5、配置application.yml

"seata.store.db..vgroup-table": vgroup_table

server:
  port: 7091

spring:
  application:
    name: seata-server

logging:
  config: classpath:logback-spring.xml
  file:
    path: ${log.home:${user.home}/logs/seata}
  extend:
    logstash-appender:
      destination: 127.0.0.1:4560
    kafka-appender:
      bootstrap-servers: 127.0.0.1:9092
      topic: logback_to_logstash

console:
  user:
    username: seata
    password: seata
seata:
  config:
    # support: nacos, consul, apollo, zk, etcd3
    type: file
  registry:
    # support: nacos, eureka, redis, zk, consul, etcd3, sofa
    type: nacos
    nacos:
      application: seata-server # 注册到 Nacos 的服务名（客户端按此名查找 TC）
      server-addr: 192.168.20.139:8848   # ★ Nacos连接地址
      group: SEATA_GROUP        # Nacos 中的分组名
      namespace: ""             # 命名空间 ID，留空 = public（注意：填 ID 不填名称）
      cluster: default          # 集群名，客户端配置必须与此一致
      username: nacos           # Nacos 控制台账号
      password: nacos           # Nacos 控制台密码
  store:
    # support: file 、 db 、 redis 、 raft
    mode: db
    db:
      datasource: druid

      url: jdbc:mysql://192.168.20.139:3306/seata?useSSL=true&serverTimezone=Asia/Shanghai
      user: seata                 # Step 4 创建的 Seata 专用账号

      global-table: global_table          # 对应的表名（和 DDL 一致，不用改）
      branch-table: branch_table
      lock-table: lock_table
      distributed-lock-table: distributed_lock
      query-limit: 100            # 单次查询最大行数

  security:

6、下载MySQL驱动。

mkdir -p /Seata/seata-server/lib/jdbc
wget -P /Seata/seata-server/lib/jdbc/ https://repo1.maven.org/maven2/com/mysql/mysql-connector-j/8.0.33/mysql-connector-j-8.0.33.jar

 

7、启动

cd /Seata/seata-server/bin
./seata-server.sh

 

8、浏览器验证

http://192.168.20.139:7091/

 

9、配 systemd 后台运行

# 先探测 JAVA_HOME（systemd 不读 profile，必须显式写入服务）
JAVA_HOME_PATH=$(dirname $(dirname $(readlink -f $(which java))))
echo "JAVA_HOME = $JAVA_HOME_PATH"

# 注意：下面 heredoc 用的是不带引号的 << EOF，bash 会在写文件那一刻把 $JAVA_HOME_PATH
# 替换成变量值——所以上面两行赋值必须在 cat 之前执行，顺序不能颠倒（否则写入空值）。
cat > /etc/systemd/system/seata.service << EOF
