seata部署文档

上传压缩包

上传压缩包 seata-server-1.4.0.tar.gz 到linux服务器 opt 下

解压

解压 seata-server-1.4.0.tar.gz

tar -zxvf seata-server-1.4.0.tar.gz

解压后的目录是 seata

seata的配置文件修改

修改 opt/seata/conf 下的 file.conf 和 registry.conf

file.conf

## transaction log store, only used in seata-server
store {
  ## store mode: file、db、redis
  mode = "db"


  ## 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.
    dbType = "mysql"
    driverClassName = "com.mysql.jdbc.Driver"
    url = "jdbc:mysql://10.100.232.173:3306/seata"
    user = "root"
    password = "123456"
    minConn = 5
    maxConn = 100
    globalTable = "global_table"
    branchTable = "branch_table"
    lockTable = "lock_table"
    queryLimit = 100
    maxWait = 5000
  }


 


}

registry.conf

registry {
  # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
  type = "nacos"
  loadBalance = "RandomLoadBalance"
  loadBalanceVirtualNodes = 10


  nacos {
    application = "seata-server"
    serverAddr = "10.100.232.172:8848"
    group = "SEATA_GROUP"
    namespace = ""
    cluster = "default"
    username = "nacos"
    password = "nacos"
  }
  
}

创建seata的数据库

在mysql上创建一个 mscm-seata-test 的数据库（你可以根据自己的喜好取名字），执行如下脚本，把表同步进去

-- -------------------------------- The script used when storeMode is 'db' --------------------------------
-- the table to store GlobalSession data
CREATE TABLE IF NOT EXISTS `global_table`
(
    `xid`                       VARCHAR(128) NOT NULL,
    `transaction_id`            BIGINT,

    PRIMARY KEY (`row_key`),
    KEY `idx_branch_id` (`branch_id`)

  DEFAULT CHARSET = utf8;

seata配置信息数据上传到nacos

创建nacos-seata文件夹，存储nacos的脚本和配置

创建 nacos-config.sh，和 nacos-config.txt

我的在一个目录下的，一会儿改下nacos-config.sh的扫描nacos-config.txt路径就行

nacos-config.txt内容

#我的只是mysql的DB模式，就需要这些，你若是用其他的，可以保留其他配置
service.vgroupMapping.my_test_tx_group=default  
service.default.grouplist=127.0.0.1:8091
service.enableDegrade=false
service.disableGlobalTransaction=false
store.mode=db
store.db.datasource=druid
store.db.dbType=mysql
store.db.driverClassName=com.mysql.jdbc.Driver
store.db.url=jdbc:mysql://10.100.232.173:3306/seata?useUnicode=true 
store.db.user=root
store.db.password=123456
store.db.minConn=5
store.db.maxConn=30
store.db.globalTable=global_table
store.db.branchTable=branch_table
store.db.queryLimit=100
store.db.lockTable=lock_table
store.db.maxWait=5000

nacos-config.sh内容：

if [[ -z ${host} ]]; then
    host=localhost

    port=8848

    password=""

nacosAddr=$host:$port
contentType="content-type:application/json;charset=UTF-8"
 
echo "set nacosAddr=$nacosAddr"
echo "set group=$group"
 
failCount=0
tempLog=$(mktemp -u)
function addConfig() {
  curl -X POST -H "${contentType}" "http://$nacosAddr/nacos/v1/cs/configs?dataId=$1&group=$group&content=$2&tenant=$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++ ))
  fi
}
 
count=0
# 刚刚$(dirname "$PWD")/nacos-seata/nacos-config.txt所在的路径，你的不一样，可以自己修改
for line in $(cat $(dirname "$PWD")/nacos-seata/nacos-config.txt | sed s/[[:space:]]//g); do
  (( count++ ))
 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

然后给nacos-config.sh执行权限即可，再执行如下命令：

sh nacos-config.sh

看下nacos

管理脚本

切换到/opt/seata的目录下，创建 seata-start.sh 和 seata-stop.sh 和 kill-process.sh

seata-start.sh 内容

nohup ./bin/seata-server.sh -p 8091 > ./logs/seata.log 2>&1 &

kill-process.sh 内容

#!/bin/sh
#根据进程名杀死进程
if [ $# -lt 1 ]
then
  echo "缺少参数：procedure_name"
  exit 1
fi
 
PROCESS=`ps -ef|grep $1|grep -v grep|grep -v PPID|awk '{ print $2}'`
for i in $PROCESS
do
  echo "Kill the $1 process [ $i ]"
  kill -9 $i
done

kill-process.sh 内容

./kill-process.sh seata

seata-stop.sh 内容

#杀死进程名字 = seata 的进程
./kill-process.sh seata

再创建一个seata-restart.sh的脚本，处理seata的重启，里面就是调用 seata-stop.sh，再调用 seata-start.sh而已；

seata-restart.sh：

#执行停止脚本
./seata-stop.sh
echo "seata正在启动......"
#执行启动脚本
./seata-start.sh
# $?代表上个命令执行状态，如果 = 0，则说明执行成功
if [ $? -eq 0 ];then
    sleep 5s
    echo "seata启动成功......"
else 
    echo "seata启动失败......"
fi

分别给这几个sh脚本执行权限，就可以直接执行对应脚本，来启动，停止，重启seata了

seata开机自启

上面的脚本是手动执行，开机不能自启，每次宕机，都要手动重启seata，太麻烦

给seata设置开机自启

1）cd etc/init.d 进入目录

2）创建文件seata

#!/bin/bash
#
#chkconfig: 345 63 37
#description: seata
#processname: seata




export JAVA_HOME=/opt/jdk8/jdk1.8.0_333
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PWD/bin:$JAVA_HOME/bin:$PATH


SEATA_HOME=/opt/seata


case $1 in
  start)
    nohup sh $SEATA_HOME/bin/seata-server.sh -p 8091 -h 10.100.232.171 > seata.out 2>&1 &
        echo $! > $SEATA_HOME/bin/seata.pid
    echo "seata is started"
    ;;
  stop)
    pid=`ps -ef|grep seata |grep -v grep|grep -v PPID|awk '{ print $2}'`
    kill -9 $pid
    echo "seata is stopped"
    ;;


  *)
    echo "start|stop|restart"
    ;;
esac
exit 0

3）给脚本添加权限chmod 755 seata

4）添加服务到开机项 chkconfig --add seata

5）设置为开机启动 chkconfig seata on

6）测试 service seata start
