linux中安装seata，并且集成到nacos

1，下载seata1.4压缩包：

https://github.com/seata/seata/releases

上传带linux服务器，并且解压，我上传到/opt/seata-1.4下

 

2，创建nacos-seata文件夹，存储nacos的脚本和配置

3，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

创建seata数据库：在你的mysql创建个seata数据库，执行下sql语句

else
 echo " init nacos config fail. "
fi

然后给nacos-config.sh执行权限即可，在执行如下命令：

sh nacos-config.sh

 

修改 seata/conf 目录中的 file.conf

修改 seata/conf 目录中的 registry.conf，注册中心的配置，我们这边采用的nacos

 type 值改为 nacos

application 是注册到nacos的seata服务名称，默认即可

serverAddr 是 nacos 服务地址

group 是 seata 在 nacos上注册服务的分组

namespace 是 nacos 命名空间ID（如果使用默认的 public 命名空间，可以注掉这行）

username和password是nacos验证，没有开启就可以注掉

创建seata的启动sh脚本

touch seata-start.sh

脚本让内容如下：
nohup ./bin/seata-server.sh -p 8091 > ./logs/seata.log 2>&1 &  后台启动

给予seata-start.sh执行权限，

启动seata即可 

 我的一开始起不起来，是因为seata用nacos-config.sh同步nacos-config.txt是，数据库的密码总是同步步到nacos中，不得已手动在nacos上建了一个 store.db.password 

 点击编辑，进去把你的数据库密码放进去就行，在点击发布

 在重新启动seata即可

./seata-start.sh 

为了方便对seata的管理，有了启动脚本，怎么没有停止和重启脚本，自己搞一个

我这里先创建一个根据进程名kill进程的一个脚本，取名 = kill-process.sh；

#!/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

再创建一个seata的stop脚本，取名 = seata-sop.sh，里面就是调用  kill-process.sh

seata-sop.sh：

#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
