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,
`status` TINYINT NOT NULL,
`application_id` VARCHAR(32),
`transaction_service_group` VARCHAR(32),
`transaction_name` VARCHAR(128),
`timeout` INT,
`begin_time` BIGINT,
`application_data` VARCHAR(2000),
`gmt_create` DATETIME,
`gmt_modified` DATETIME,
PRIMARY KEY (`xid`),
KEY `idx_gmt_modified_status` (`gmt_modified`, `status`),
KEY `idx_transaction_id` (`transaction_id`)
) ENGINE = InnoDB
DEFAULT CHARSET = utf8;
-- the table to store BranchSession data
CREATE TABLE IF NOT EXISTS `branch_table`
(
`branch_id` BIGINT NOT NULL,

) ENGINE = InnoDB
DEFAULT CHARSET = utf8;
-- the table to store lock data
CREATE TABLE IF NOT EXISTS `lock_table`
(

`transaction_id` BIGINT,
`branch_id` BIGINT NOT NULL,
`resource_id` VARCHAR(256),

`pk` VARCHAR(36),
`gmt_create` DATETIME,
`gmt_modified` DATETIME,
PRIMARY KEY (`row_key`),
KEY `idx_branch_id` (`branch_id`)
) ENGINE = InnoDB
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：

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
