Seata Server服務(wù)端搭建
一、官網(wǎng)地址
二显沈、Seata Server 下載
這里地址為
1.3.0版本
- Linux
wget https://github.com/seata/seata/releases/download/v1.3.0/seata-server-1.3.0.zip
三汇跨、修改配置文件
配置文件主要有：
registry.conffile.conf
registry.conf: Seata 服務(wù)注冊(cè)中心地址坝辫，配置中心地址
file.conf: 當(dāng)配置中心使用file時(shí)，此配置文件生效狸涌。配置store存儲(chǔ)配置這里我們使用
eureka做為注冊(cè)中心，Apollo做為配置中心
registry.conf
registry {
# file 、nacos 胀屿、eureka、redis包雀、zk宿崭、consul、etcd3馏艾、sofa
type = "eureka"
# 配置eureka地址
eureka {
serviceUrl = "http://10.0.17.92:9001/eureka"
application = "seata-server"
weight = "1"
}
...
file {
name = "file.conf"
}
}
config {
# file劳曹、nacos 、apollo琅摩、zk铁孵、consul、etcd3
#type = "file"
type = "apollo"
# 配置中心配置apollo地址和namespace
apollo {
appId = "seata-server"
apolloMeta = "http://10.0.17.92:9083"
namespace = "application"
}
file {
name = "file.conf"
}
}
file.conf
## transaction log store, only used in seata-server
store {
## store mode: file房资、db蜕劝、redis
mode = "db"
## file store property
file {
## store location dir
dir = "sessionStore"
# branch session size , if exceeded first try compress lockkey, still exceeded throws exceptions
maxBranchSessionSize = 16384
# globe session size , if exceeded throws exceptions
maxGlobalSessionSize = 512
# file buffer size , if exceeded allocate new buffer
fileWriteBufferCacheSize = 16384
# when recover batch read size
sessionReloadReadSize = 100
# async, sync
flushDiskMode = async
}
## database store property
db {
## the implement of javax.sql.DataSource, such as DruidDataSource(druid)/BasicDataSource(dbcp)/HikariDataSource(hikari) etc.
datasource = "druid"
## mysql/oracle/postgresql/h2/oceanbase etc.

driverClassName = "com.mysql.cj.jdbc.Driver"
url = "jdbc:mysql://10.0.17.122:3306/seata"
user = "root"
password = "Pdhn^456"
minConn = 5
maxConn = 30
globalTable = "global_table"
branchTable = "branch_table"
lockTable = "lock_table"
queryLimit = 100
maxWait = 5000
}
## redis store property
redis {
host = "127.0.0.1"
port = "6379"
password = ""
database = "0"
minConn = 1
maxConn = 10
queryLimit = 100
}
}
Apollo配置Server配置
主要修改：數(shù)據(jù)庫地址 用戶名 密碼等
- 注意：mysql 版本問題 1.3.0后，Seata使用mysql 8.0版本
- 使用 8.0版本后轰异，driverClassName = com.mysql.cj.jdbc.Driver 岖沛。否則會(huì)報(bào)錯(cuò)：

四、Seata-Server啟動(dòng)
- 先保證配置
eurekaapollo配置搭独，啟動(dòng)注冊(cè)中心和配置中心
-
Apollo配置
[圖片上傳失敗...(image-646e30-1623312838097)]
- 進(jìn)入到：
seata/bin目錄
nohup sh seata-server.sh -h 10.0.17.92 -p 8091 &
Eureka
[圖片上傳失敗...(image-c5fe2a-1623312838097)]
五婴削、Docker啟動(dòng) Seata server
1. 拉取 seata-server鏡像
docker pull docker.io/seataio/seata-server:1.3.0
2. 修改配置文件registry.conf
- 配置 Apollo
registry {
# file 、nacos 牙肝、eureka唉俗、redis嗤朴、zk、consul虫溜、etcd3雹姊、sofa
type = "eureka"
loadBalance = "RandomLoadBalance"
loadBalanceVirtualNodes = 10
eureka {
serviceUrl = "http://10.0.17.92:9001/eureka"
application = "seata-server"
weight = "1"
}
file {
name = "file.conf"
}
}
config {
# file、nacos 衡楞、apollo吱雏、zk、consul瘾境、etcd3
type = "apollo"
apollo {
appId = "seata-server"
apolloMeta = "http://10.0.17.92:9083"
namespace = "application"
}
file {
name = "file.conf"
}
}
3. 啟動(dòng)腳本
start.sh
SEATA_PORT : 自定義端口
SERVER_NODE: 集群環(huán)境下歧杏，指定節(jié)點(diǎn)
seata日志目錄：/root/logs/seata ，可掛載到服務(wù)器本地目錄
#!/bin/bash
docker stop seata-server;
docker container rm seata-server;
docker run --name seata-server -it -d -p 8091:8091 \
-e SEATA_CONFIG_NAME=file:/root/seata/config/registry \
-e SEATA_IP=10.0.17.92 \
-e SEATA_PORT=8091 \
-e SERVER_NODE=1 \
-v /opt/logs/seata:/root/logs/seata \
-v /opt/seata/config:/root/seata/config \
- v /opt/seata/config/libs/mysql-connector-java-8.0.21.jar:/root/seata/config/libs/mysql-connector-java-8.0.21.jar \
--net=bridge --restart=always docker.io/seataio/seata-server:1.3.0
六寄雀、 Docker Compose 啟動(dòng) Seata server
注意數(shù)據(jù)庫版本問題得滤，1.3.0版本后 mysql驅(qū)動(dòng)為 8.0版本
- 在config目錄中，配置`mysql-connector-java-8.0.21.jar`驅(qū)動(dòng)
Apollo數(shù)據(jù)庫驅(qū)動(dòng)cj盒犹，連接地址加characterEncoding=utf-8&serverTimezone=UTCstore.db.driverClassName = com.mysql.cj.jdbc.Driver store.db.url = jdbc:mysql://10.0.17.122:3306/seata?useUnicode=true&characterEncoding=utf-8&serverTimezone=UTC
- 啟動(dòng)容器
docker-compose up -d
1. docker-compose.yml配置文件
version: "3"
services:
seata-server:
image: seataio/seata-server:1.3.0
container_name: seata-server
hostname: seata-server
ports:
- "8091:8091"
volumes:
- "/opt/seata/config:/root/seata/config"
- "/opt/seata/config/libs/mysql-connector-java-8.0.21.jar:/root/seata/config/libs/mysql-connector-java-8.0.21.jar"
environment:
- SEATA_CONFIG_NAME=file:/root/seata/config/registry
- SEATA_IP=10.0.17.92
- SEATA_PORT=8091
- STORE_MODE=db
restart: always
deploy:
resources:
limits:
cpus: '0.3'
memory: 300M
2. registry.conf
registry {
# file 懂更、nacos 、eureka急膀、redis沮协、zk、consul卓嫂、etcd3慷暂、sofa
type = "eureka"
loadBalance = "RandomLoadBalance"
loadBalanceVirtualNodes = 10
eureka {
serviceUrl = "http://10.0.17.92:9001/eureka"
application = "seata-server"
weight = "1"
}
file {
name = "file.conf"
}
}
config {
# file、nacos 晨雳、apollo行瑞、zk、consul餐禁、etcd3
type = "apollo"
apollo {
appId = "seata-server"
apolloMeta = "http://10.0.17.92:9083"
namespace = "application"
}
file {
name = "file:/root/seata/config/file.conf"
}
}
3. 異常 database
com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create connection to database server
15:09:54.010 ERROR --- [ionPool-Create-1072506992] com.alibaba.druid.pool.DruidDataSource : create connection SQLException, url: jdbc:mysql://10.0.17.122:3306/seata?useUnicode=true, errorCode 0, state 08001

4. 進(jìn)入seata server 容器
[root@lipei92 seata]# docker ps|grep seata
55af30b183b7 seataio/seata-server:1.4.1 "java -Djava.secur..." 4 minutes ago Up 8 seconds 0.0.0.0:8091->8091/tcp seata-server
[root@lipei92 seata]# docker exec -it 55af30b183b7 sh
/seata-server # pwd
/seata-server
九血久、參考文檔
-
Docker-compose主要參考
使用docker安裝seata-server，mysql8引擎帮非，nacos作為注冊(cè)和配置中心
-
Docker主要參考文檔
docker快速部署一個(gè)seata-server+向nacos推送配置
-
Seata Server數(shù)據(jù)版本升級(jí) 8.0后報(bào)異常
