1、创建目录

mkdir -p /Seata && cd /Seata

 

2、下载并解压

wget https://downloads.apache.org/incubator/seata/2.6.0/apache-seata-2.6.0-incubating-bin.tar.gz
tar -xzf apache-seata-2.6.0-incubating-bin.tar.gz
cd apache-seata-2.6.0-incubating-bin/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'

6、下载驱动。

cd /Seata/apache-seata-2.6.0-incubating-bin/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

# 1. 备份并移除老客户端（不能只改名留在 lib 里？其实改后缀为 .bak 即可，PropertiesLauncher 只认 .jar）  
mv nacos-client-1.4.6.jar nacos-client-1.4.6.jar.bak  
  
# 2. 下载 2.0.4（官方 PR #8097 指定的版本，走 gRPC 9848 端口，无需 v1 API）  
wget https://repo1.maven.org/maven2/com/alibaba/nacos/nacos-client/2.0.4/nacos-client-2.0.4.jar  
  
# 3. ★ nacos-client 2.x 多出两个依赖（reflections、javassist），Seata 发行包里没有，必须补上  
#    缺 reflections 会报 NoClassDefFoundError: org/reflections/Reflections  
#    缺 javassist   会报 NoClassDefFoundError: javassist/bytecode/ClassFile  
wget https://repo1.maven.org/maven2/org/reflections/reflections/0.9.11/reflections-0.9.11.jar  
wget https://repo1.maven.org/maven2/org/javassist/javassist/3.29.2-GA/javassist-3.29.2-GA.jar  
  
# 4. 确认（nacos-client 2.0.4 约 14MB，reflections 约 130KB，javassist 约 500KB），然后重启 seata-server  
ls -lh nacos-client* reflections* javassist*

 

7、启动seata-server

cd /Seata/apache-seata-2.6.0-incubating-bin/seata-server/bin
./seata-server.sh

#当前情况如果要停服务
kill $(pgrep -f seata-server.jar) 2>/dev/null;

 

8、配置seata-namingserver的application.yml

cd /Seata/apache-seata-2.6.0-incubating-bin/seata-namingserver/conf
vim application.yml

9、启动seata-namingserver

cd /Seata/apache-seata-2.6.0-incubating-bin/seata-namingserver/bin
./seata-namingserver.sh

#当前情况如果要停服务
kill $(pgrep -f seata-namingserver.jar) 2>/dev/null;

 

10、浏览器验证

11、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"
