spring cloud alibaba之seata1.4 安装记录（上）
- 第一步下载seata-1.4服务端 截止2021-1-12 seata最新版本为1.4
- 下载地址https://github.com/seata/seata/releases/tag/v1.4.0 （win下载zip linux下载tar.gz)
- https://github.com/seata/seata/releases/download/v1.4.0/seata-server-1.4.0.tar.gz 我linux的实际下载地址
- 安装服务端
- 解压缩 tar -zxvf seata-server-1.4.0.tar.gz
- 修改注册中心配置文件（我这里使用spring cloud alibaba的naocs注册中心）
- vim ./seata/conf/registry.conf
- 主要修改注册中心地址以及账号密码 主要修改两个地址
-
1 registry { 2 # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa 3 type = "nacos" #修改为nacos 4 loadBalance = "RandomLoadBalance" 5 loadBalanceVirtualNodes = 10 6 7 nacos { 8 application = "seata-server" 9 serverAddr = "nacos.baidu.cn:80"#修改nacos地址（这里写你自己的） 10 group = "SEATA_GROUP" 11 namespace = "" 12 cluster = "default" 13 username = "nacos" #nacos账号 14 password = "nacos" #nacos密码 15 } 58 config { 59 # file、nacos 、apollo、zk、consul、etcd3 60 type = "nacos" #修改为nacos 61 62 nacos { 63 serverAddr = "nacos.baidu.cn:80" #修改nacos地址（这里写你自己的） 64 namespace = "" 65 group = "SEATA_GROUP" 66 username = "nacos" #nacos账号 67 password = "nacos" #nacos密码 68 } 69 } -
接下来修改mysql配置（我这里使用数据库的形式保存seata的数据）
-
vim seata/conf/file.conf 需要修改的地方我用#号在后面注明了 （这里需要先创建一个数据库 保存seata的数据脚本我放后面）
-
1 ## transaction log store, only used in seata-server 2 store { 3 ## store mode: file、db、redis 4 mode = "db" #这里改成DB 5 6 ## file store property 7 file { 8 ## store location dir 9 dir = "sessionStore" 10 # branch session size , if exceeded first try compress lockkey, still exceeded throws exceptions 11 maxBranchSessionSize = 16384 12 # globe session size , if exceeded throws exceptions 13 maxGlobalSessionSize = 512 14 # file buffer size , if exceeded allocate new buffer 15 fileWriteBufferCacheSize = 16384 16 # when recover batch read size 17 sessionReloadReadSize = 100 18 # async, sync 19 flushDiskMode = async 20 } 21 22 ## database store property 23 db { 24 ## the implement of javax.sql.DataSource, such as DruidDataSource(druid)/BasicDataSource(dbcp)/HikariDataSource(hikari) etc. 25 datasource = "druid" 26 ## mysql/oracle/postgresql/h2/oceanbase etc. 27 dbType = "mysql" 28 driverClassName = "com.mysql.jdbc.Driver" #注意mysql5和8的驱动不一样我使用的是5 29 url = "jdbc:mysql://127.0.0.1:3307/seata?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf8&useSSL=tru" #写你的自己的mysql地址 这里需要先新建一个seata数据库 30 user = "mysql" #你的mysql用户名 31 password = "mysql" #你的mysql密码 32 minConn = 5 33 maxConn = 100 34 globalTable = "global_table" 35 branchTable = "branch_table" 36 lockTable = "lock_table" 37 queryLimit = 100 38 maxWait = 5000 39 }
-
-
先建立seata数据库我把脚本放下面 实际地址 https://github.com/seata/seata/blob/1.4.0/script/server/db/mysql.sql
并建立下面三张表（branch_table, global_table, lock_table），创建undo_log表放到业务库中
-- -------------------------------- 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,
`xid` VARCHAR(128) NOT NULL,
`transaction_id` BIGINT,
`resource_group_id` VARCHAR(32),
`resource_id` VARCHAR(256),
`branch_type` VARCHAR(8),
`status` TINYINT,
`client_id` VARCHAR(64),
`application_data` VARCHAR(2000),
`gmt_create` DATETIME(6),
`gmt_modified` DATETIME(6),
PRIMARY KEY (`branch_id`),
KEY `idx_xid` (`xid`)
) ENGINE = InnoDB
DEFAULT CHARSET = utf8;
-- the table to store lock data
CREATE TABLE IF NOT EXISTS `lock_table`
(
`row_key` VARCHAR(128) NOT NULL,
`xid` VARCHAR(96),
`transaction_id` BIGINT,
`branch_id` BIGINT NOT NULL,
`resource_id` VARCHAR(256),
`table_name` VARCHAR(32),
`pk` VARCHAR(36),
`gmt_create` DATETIME,
`gmt_modified` DATETIME,
PRIMARY KEY (`row_key`),
KEY `idx_branch_id` (`branch_id`)
) ENGINE = InnoDB
DEFAULT CHARSET = utf8;
接下来就是启动服务了 最后加一个 & 不然是当前脚本是以前台方式启动 就是窗口不能关闭 关闭了服务就完了
./bin/seata-server.sh &
这样就算启动成功了 默认 8091端口
去看看注册中心 有没有注册上seata的服务
好 服务端 正式安装完成 启动也OK了。
后续发现一个问题 nacos上找不到seata服务
io.seata.common.exception.FrameworkException: can not connect to services-server.
at io.seata.core.rpc.netty.NettyClientBootstrap.getNewChannel(NettyClientBootstrap.java:182) ~[seata-all-1.4.0.jar:1.4.0]
at io.seata.core.rpc.netty.NettyPoolableFactory.makeObject(NettyPoolableFactory.java:58) ~[seata-all-1.4.0.jar:1.4.0]
at io.seata.core.rpc.netty.NettyPoolableFactory.makeObject(NettyPoolableFactory.java:34) ~[seata-all-1.4.0.jar:1.4.0]
上面是官方给出的解决方案 我按提示
求看了下nacos注册的seata服务器地址 注册到127.0.0.1:8091 下面去了
我按文档上的说明
seata/bin/seata-server.sh -p 8091 -h 192.168.50.235 &
-p是指定端口 -h 是指定IP 现在好像还不支持域名 启动后就OK了，如果你是在一台机器上测试 应该不用改这个
——————————————————————————————————————————————————————————————————————————————
接下来将配置项注册到naocs上面(这个步骤的意思是把一些seta需要用到的配置项已脚本的形式添加到nacos配置中心 不然一个一个添加 那不的累死了)
nacos是配置+服务发现以及管理中心（这里不展开 nacos只是有空在写）
查看脚本
https://github.com/seata/seata/blob/1.4.0/script/config-center/nacos/nacos-config.sh
这个脚本是添加配置的脚本

fi把上面的脚本保存为nacos-config.sh脚本 可以使用vim nacos-config.sh复制上面的脚本进去
chmod +x nacos-config.sh 添加可执行权限
./nacos-config.sh -h nacos.baidu.cn -p 80 -g SEATA_GROUP -u nacos -w nacos
参数解释
-h nacos注册中心地址
-p nacos注册中心端口
-g nacos中注册的分组（命名空间 分组 dataid 去了解nacos知识点 这里写SEATA_GROUP就行）
-u nacos注册中心账号
-w nacos注册中心密码
这里报错了 config.txt: No such file or directory 这个config.txt是真正的配置项（nacos-config.sh 是执行添加配置的脚本 真正的配置项目在这个config.txt文件里面）
[yangjie@localhost seata]$ ./nacos-config.sh -h nacos..cn -p 80 -g SEATA_GROUP -u nacos -w nacos
set nacosAddr=nacos.baidu.cn:80
set group=SEATA_GROUP

Init nacos config finished, please start seata-server. 看起来像是让我先注册 在启动seata-server 我们已经启动了 暂时不管 （后续有问题在说）
这里配置也配置也添加到nacos配置中心了
————————————————————————————————————————
后记 后续发现需要修改config.txt的一些配置 这里面的配置项意义后续在研究这里暂时只修改这两个地方
修改完需要重新执行 ./nacos-config.sh -h nacos.baidu.cn -p 80 -g SEATA_GROUP -u nacos -w nacos 脚本配置到nacos的配置中心
修改service.vgroupMapping和数据库地址
service.vgroupMapping.my_test_tx_group=default 中的my_test_tx_group 需要改成项目中yml中的配置
——————————————————————————————————————————————————————————
接下来就是客户端使用的配置了
好像有点多啊 12点了 明天搭建 客户端使用的时候在写吧，在下一篇写。有点杂乱 就是一个安装笔记，大家将就着看。希望能帮助到其他人。
