linux通过nginx部署jar包

1、打开防火墙端口

打开该jar包运行时所使用的端口，注意改端口不可以和已经部署的项目冲突，不然启动不成功（端口占用）

防火墙操作：
	// 开启53端口
	firewall-cmd --add-port=53/tcp --permanent --zone=public
	// 重载配置
	firewall-cmd --reload
	// 查看端口
	firewall-cmd --list-port
	#查看防火墙状态
 	systemctl status firewalld
 	# 开启
 	sudo service firewalld start
 	# 重启
 	sudo service firewalld restart
	# 关闭
 	sudo service firewalld stop

2、打包jar包并放置至指定路径

3、复制indolent.properties和build.sh文件

indolent.properties：

#虚拟机参数，注释掉默认为-Xms1024m -Xmx2048m
VMparam=-Xms256m -Xmx256m 
#nacos配置，如果没有nacos则注释掉
envparam=--spring.cloud.nacos.config.server-addr=xxx.xxx.x.xxx:8848 --spring.cloud.nacos.config.namespace=xxxxxxxxxxxxxxx --godata.debug=true --spring.config.location=classpath:/bootstrap.properties

build.sh：

#! /bin/sh

		exit
    fi

else	#首次生成，直接初始化并创建
	init
fi

4、运行build.sh

命令为：sh build.sh

执行命令后文文件夹会多出一个文件夹autoScript

启动命令：sh autoScript/startup.sh

重启命令：sh autoScript/restart.sh

停止命令：sh autoScript/shutdown.sh

显示日志：sh autoScript/showlog.sh

本分jar包：sh autoScript/backup.sh

5、nginx接口转发

配置/xxx/nginx/conf 中的nginx.conf，参考如下：

location /api/fwq/ {

client_max_body_size 100m;

proxy_pass http://192.168.2.179:19021/api/fwq/;

proxy_cookie_path /api/fwq/ /api/fwq/;

proxy_set_header Host $host:$server_port;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header REMOTE-HOST $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}
