Linux部署系统

Linux安装Java环境

mkdir /usr/java

2、将jdk-11.0.18_linux-x64_bin.tar.gz拷贝到java目录下

jdk11下载地址：https://www.oracle.com/java/technologies/downloads/#java11

3、解压jdk到当前目录

tar -zxvf jdk-11.0.18_linux-x64_bin.tar.gz

4、安装完毕为他建立一个链接以节省目录长度

ln -s /usr/java/jdk-11.0.18 /usr/jdk11

5、编辑配置文件，配置环境变量

vi /etc/profile

6、在文本的末尾添加如下内容：

export JAVA_HOME=/usr/jdk11
export CLASSPATH=$JAVA_HOME/lib/
export PATH=$PATH:$JAVA_HOME/bin

7、执行命令刷新：

source /etc/profile

8、查看是否安装成功

java -version

打包发布

1、在idea的maven中先clean，禁用test选项，后package打包，则可以在target目录中得到jar包文件；

2、将生成的jar包文件拷入/home/filename/中，app.sh脚本拷进filename中

3、sh app.sh start 运行app.sh文件则可以启动系统，watch.out为启动日志。

4、执行sh文件出错，将windows格式转换为unix格式。

yum install dos2unix
dos2unix app.sh

5、查看实时日志

tail -f watch.out

6、开放端口号并刷新

4、开放指定端口
firewall-cmd --zone=public --add-port=10090/tcp --permanent

5、重启防火墙
firewall-cmd --reload

app.sh脚本

#!/bin/sh

# 获得本地路径
CURR_FOLDER=`pwd`
