seata执行闪退_seata-server安装、运行

seata-server为seata中的事务协调器。

只能在jdk8环境

seata的wiki

一、下载并安装

wget -P /opt/downloads https://github.com/seata/seata/releases/download/v0.9.0/seata-server-0.9.0.tar.gz

mkdir /opt/seata-servertar zxvf /opt/downloads/seata-server-0.9.0.tar.gz -C /opt/seata-server

mv /opt/seata-server/seata/* /opt/seata-server

rm -r /opt/seata-server/seata/

二、导入配置

本文使用nacos作为配置中心和服务发现，file、apollo、redis、zk、consul等也可以举一反三。

我们这里用默认的导入先让seata-server跑起来，过后对着file.conf和java程序启动后的报错调整，重新导入即可。

vim /opt/seata-server/conf/nacos-config.txt

以下是我根据自己的环境修改后的配置值

建立集群数据库

注意版本对应分支，官方链接指向了develop分支sql不同是会报错的

--the table to store GlobalSession data

drop table if exists`global_table`;create table`global_table` (

`xid`varchar(128) not null,

`transaction_id`bigint,

`status`tinyint not null,

`application_id`varchar(32),

`transaction_service_group`varchar(32),

`transaction_name`varchar(128),

`begin_time`bigint,

`application_data`varchar(2000),

`gmt_modified`datetime,primary key(`xid`),key`idx_gmt_modified_status` (`gmt_modified`, `status`),key`idx_transaction_id` (`transaction_id`)

);--the table to store BranchSession data

drop table if exists`branch_table`;create table`branch_table` (

drop table if exists`lock_table`;create table`lock_table` (

`xid`varchar(96),

`transaction_id`long,

`branch_id`long,

`resource_id`varchar(256) ,

`table_name`varchar(32) ,

`pk`varchar(36) ,

`gmt_create`datetime,

`gmt_modified`datetime,primary key(`row_key`)

);

store.db.datasource的选择 ## the implement of javax.sql.DataSource, such as DruidDataSource(druid)/BasicDataSource(dbcp) etc.

store.db.driver-class-name = "com.mysql.jdbc.Driver"   store.db.driver-class-name = "com.mysql.cj.jdbc.Driver"

选择druid和com.mysql.jdbc.Driver(目前seata驱动为5.1.30)

导入配置到nacos。

格式为sh nacos-config.sh $Nacos-Server-IP

因为nacos-config.sh脚本中已经把8848端口写死，如果你的nacos-server不是8848端口，请修改nacos-config.sh。

cd /opt/seata-server/conf/

bash /opt/seata-server/conf/nacos-config.sh nacosserver

nacosserver是nacos的ip

脚本执行最后输出 "init nacos config finished, please start seata-server." 说明推送配置成功。若想进一步确认可登陆Nacos控制台->配置列表->筛选查询Group为SEATA_GROUP的配置项。

将/opt/seata-server/conf/nacos-config.txt 脚本修改后重新导入即可。

三、启动seata-server(事务协调器)

修改日志目录(非必须)

vim /opt/seata-server/conf/logback.xml

改为

sudo mkdir -p /var/log/seata-server;sudo chmod -R 777 /var/log/seata-server

配置修改

vim /opt/seata-server/conf/registry.conf 并复制到java代码的properties目录下

registry {

# file 、nacos 、eureka、redis、zk、consul、etcd3、sofa

type ="nacos"nacos {

serverAddr ="nacosserver"namespace ="public"cluster ="default"}

eureka {

serviceUrl ="http://localhost:8761/eureka"application ="default"weight ="1"}

redis {

serverAddr ="localhost:6379"db ="0"}

zk {

cluster ="default"serverAddr ="127.0.0.1:2181"session.timeout =6000connect.timeout =2000}

consul {

cluster ="default"serverAddr ="127.0.0.1:8500"}

etcd3 {

cluster ="default"serverAddr ="http://localhost:2379"}

sofa {

serverAddr ="127.0.0.1:9603"application ="default"region ="DEFAULT_ZONE"datacenter ="DefaultDataCenter"cluster ="default"group ="SEATA_GROUP"addressWaitTime ="3000"}

file {

name ="file.conf"}

}

config {

# file、nacos 、apollo、zk、consul、etcd3

type ="nacos"nacos {

serverAddr ="nacosserver"namespace =""}

consul {

serverAddr ="127.0.0.1:8500"}

apollo {

app.id ="seata-server"apollo.meta ="http://192.168.1.204:8801"}

zk {

serverAddr ="127.0.0.1:2181"session.timeout =6000connect.timeout =2000}

etcd3 {

serverAddr ="http://localhost:2379"}

file {

name ="file.conf"}

}

注：serverAddr不要填端口号   public为小写

有处BUG：config.nacos.namespace="public"的值要去掉public写成""

启动格式sh seata-server.sh $LISTEN_PORT $PATH_FOR_PERSISTENT_DATA $IP(此参数可选)

$IP参数 用于多IP环境下指定 Seata-Server 注册服务的IP    虽然是可选，但还是要填，之前我偷懒没填，一大堆虚拟ip各种乱定位。

命令启动

sh /opt/seata-server/bin/seata-server.sh -p 8091 -h 192.168.0.101 -m db -n 1

守护进程启动

vim /opt/seata-server/startup.sh

填入

#!/bin/bash

sh /opt/seata-server/bin/seata-server.sh -p 8091 -h 192.168.0.101 -m db -n 1

vim /lib/systemd/system/seata-server.service

文件中填入

[Unit]

Description=seata-serverAfter=syslog.target network.target remote-fs.target nss-lookup.target

[Service]Type=simpleExecStart=/opt/seata-server/startup.shRestart=alwaysPrivateTmp=true[Install]WantedBy=multi-user.target

赋予权限

chmod 777 /opt/seata-server/startup.sh

chmod 777 /lib/systemd/system/seata-server.service

启用服务

systemctl enable seata-server.service

systemctl daemon-reload

运行

systemctl start seata-server.service

查看状态

systemctl status seata-server.service

查看进程

ps -ef|grep seata-server

运行成功后可在Nacos控制台的 服务列表 看到 服务名serverAddr的条目

查看日志

sudo journalctl -u seata-server

sudo journalctl -u seata-server --since="2019-11-11 11:11:11"

sudo journalctl -u seata-server --since "30 min ago"

sudo journalctl -u seata-server --since yesterday

sudo journalctl -u seata-server --since "2019-11-10" --until "2018-11-11 11:11"

sudo journalctl -u seata-server --since 04:00 --until "2 hour ago"

四、创建数据表

(创建mysql数据库略)

UNDO_LOG table is required by SEATA AT mode.

--for AT mode you must to init this sql for you business databese. the seata server not need it.

drop table`undo_log`;CREATE TABLE`undo_log` (

`id`bigint(20) NOT NULL AUTO_INCREMENT COMMENT 'increment id',

`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` longblobNOT NULL COMMENT 'rollback info',

`log_status`int(11) NOT NULL COMMENT '0:normal status,1:defense status',

`log_created`datetime NOT NULL COMMENT 'create datetime',

`log_modified`datetime NOT NULL COMMENT 'modify datetime',

`ext`varchar(100) DEFAULT NULL COMMENT 'reserved field',PRIMARY KEY(`id`),UNIQUE KEY`ux_undo_log` (`xid`,`branch_id`)

) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 COMMENT='AT transaction mode undo table';

每个业务数据库都要建一个undo_log表
