seata集群部署单机版和集群版

一、 单机版

a) 安装jdk8

tar -zxvf jdk-8u261-linux-x64.tar.gz && \
echo "export JAVA_HOME&＃61;/home/csii/jdk1.8.0_261
export PATH&＃61;\$JAVA_HOME/bin:\$PATH
export CLASSPATH&＃61;.\$JAVA_HOME/lib/dt.jar:\$JAVA_HOME/lib/tools.jar" >> ~/.bash_profile && \
source ~/.bash_profile && \
java -version


b) 安装nacos&＃xff1a;

从seata官网 https://github.com/seata/seata/releases 下载安装包&＃xff0c;最新正式版&＃xff1a;seata-server-1.4.0.tar.gz&＃xff0c;直接解压

tar -zxf seata-server-1.4.0.tar.gz


c) 修改registry.conf文件&＃xff1a;

cd seata/conf


vi registry.conf

registry {# file 、nacos 、eureka、redis、zk、consul、etcd3、sofatype &＃61; "nacos" # 这里修改为nacosnacos {serverAddr &＃61; "192.168.0.201:8848" # 这里填你的nacos地址namespace &＃61; ""
cluster &＃61; "default"
username &＃61; "nacos"
password &＃61; "nacos"}
}config {# file、nacos 、apollo、zk、consul、etcd3type &＃61; "file"file {name &＃61; "file.conf"}
}


d) 启动

cd ../bin
nohup sh seata-server.sh -p 8091 -h 192.168.100.206 -m file &> seata.log &


-p 指定启动seata server的端口号。
-h 指定seata server所绑定的主机。
-m 事务日志、事务执行信息存储的方式&＃xff0c;目前支持file&＃xff08;文件方式&＃xff09;、db&＃xff08;数据库方式&＃xff0c;建表语句请查看config/db_store.sql、config/db_undo_log.sql&＃xff09;

tail -1000f seata.log


二、 集群版(三个节点同时操作)

a) 安装jdk8

tar -zxvf jdk-8u261-linux-x64.tar.gz && \
echo "export JAVA_HOME&＃61;/home/csii/jdk1.8.0_261
export PATH&＃61;\$JAVA_HOME/bin:\$PATH
export CLASSPATH&＃61;.\$JAVA_HOME/lib/dt.jar:\$JAVA_HOME/lib/tools.jar" >> ~/.bash_profile && \
source ~/.bash_profile && \
java -version


b) 安装seata

从seata官网 https://github.com/seata/seata/releases 下载安装包&＃xff0c;最新正式版&＃xff1a;seata-server-1.4.0.tar.gz&＃xff0c;直接解压

tar -zxf nacos-server-2.0.0-ALPHA.1.tar.gz


c) 配置file文件

进入conf目录

cd seata/conf


vim file.conf

## transaction log store, only used in seata-server
store {## store mode: file、db、redismode &＃61; "db" #选择db模式## file store propertyfile {## store location dirdir &＃61; "sessionStore"# branch session size , if exceeded first try compress lockkey, still exceeded throws exceptionsmaxBranchSessionSize &＃61; 16384# globe session size , if exceeded throws exceptionsmaxGlobalSessionSize &＃61; 512# file buffer size , if exceeded allocate new bufferfileWriteBufferCacheSize &＃61; 16384# when recover batch read sizesessionReloadReadSize &＃61; 100# async, syncflushDiskMode &＃61; async}## database store propertydb {## the implement of javax.sql.DataSource, such as DruidDataSource(druid)/BasicDataSource(dbcp)/HikariDataSource(hikari) etc.datasource &＃61; "druid"## mysql/oracle/postgresql/h2/oceanbase etc.dbType &＃61; "mysql"
driverClassName &＃61; "com.mysql.jdbc.Driver"
#填写mysql的jdbcurl &＃61; "jdbc:mysql://192.168.100.205:3306/seata"user &＃61; "seata"password &＃61; "seata"minConn &＃61; 5maxConn &＃61; 100globalTable &＃61; "global_table"branchTable &＃61; "branch_table"lockTable &＃61; "lock_table"queryLimit &＃61; 100maxWait &＃61; 5000}service {vgroupMapping.storage-service-group&＃61; "default"vgroupMapping.order-service-group&＃61; "default"vgroupMapping.business-service-group&＃61; "default"}
}


d) 配置MySQL数据库

创建seata数据库

create database seata;


创建mysql用户seata/seatapass

create user &＃39;seata&＃39;&＃64;&＃39;%&＃39; identified by &＃39;seatapass&＃39;;
grant all privileges on seata.* to &＃39;seata&＃39;&＃64;&＃39;%&＃39; identified by &＃39;seatapass&＃39;;


执行建表语句

e) 配置registry文件

vim application.properties

registry {# file 、nacos 、eureka、redis、zk、consul、etcd3、sofatype &＃61; "nacos"loadBalance &＃61; "RandomLoadBalance"loadBalanceVirtualNodes &＃61; 10nacos {application &＃61; "seata-server1" #每个节点命名不同1&＃xff0c;2&＃xff0c;3serverAddr &＃61; "192.168.100.201:8848,192.168.100.202:8848,192.168.100.203:8848" #nacos地址group &＃61; "SEATA_GROUP"namespace &＃61; ""cluster &＃61; "default"username &＃61; "nacos"password &＃61; "nacos" #nacos登陆账密}
}config {# file、nacos 、apollo、zk、consul、etcd3type &＃61; "file"file {name &＃61; "file.conf"}}


f) 启动seata

cd bin/
sh seata-server.sh -p 8091 -h 192.168.100.206 -m db -n 1 &> seata.log &


-h 为注册到注册中心的地址&＃xff0c;通常为seata自身IP
#另外两节点启动

sh seata-server.sh -p 8091 -h 192.168.100.207 -m db -n 2 &> seata.log &
sh seata-server.sh -p 8091 -h 192.168.100.208 -m db -n 3 &> seata.log &


g) 启动成功 登陆nacos控制台查看

http://192.168.100.203:8848/nacos


h) 开机自启

1节点
vi startseata.sh

sh /home/ywzt/seata-server.sh -p 8091 -h 192.168.100.206 -m file &> seata.log &


2节点
vi startseata.sh

sh /home/ywzt/seata-server.sh -p 8091 -h 192.168.100.206 -m file &> seata.log &


3节点
vi startseata.sh

sh /home/ywzt/seata-server.sh -p 8091 -h 192.168.100.206 -m file &> seata.log &


三个节点操作
&＃xff08;使用root用户操作&＃xff09;
vi /etc/rc.d/rc.local
在最后一行加上

su - ywzt -c "/home/ywzt/seata/startseata.sh"
chmod &＃43;x /etc/rc.d/rc.local
