在linux服务器上使用软连接进行启动jar包

一 使用软连接启动jar包

1.1 软连接

使用 ln -fs   xxx/resurce.jar     /xxx/destation.jar

软连接就是创建快捷方式。这里就是把xxx/resurce.jar这个原始的jar创建到 /xxx/这个目录下，jar包的名字为destation.jar ;也就是说 /xxx/destation.jar是xxx/resurce.jar的快捷方式。

1.2 操作案例

1.将windows上的jar包，上传到linux服务器的/root/export/servers目录下，如下图所示：

2.在/root/bigdata-software这个目录下，创建一个快捷方式

[root@192 ~]# ln -sf /root/export/servers/00-spt-test-1.0-SNAPSHOT.jar  /root/bigdata-software/spt-test.jar

3.进入到/root/bigdata-software这个目录下，启动jar包

[root@192 ~]# cd /root/bigdata-software/
[root@192 bigdata-software]# ls
apache-tomcat-8.5.6.tar.gz  influxdb-1.7.9.x86_64.rpm  jdk-8u171-linux-x64.tar.gz  spt-test.jar  zookeeper-3.4.8.tar.gz
[root@192 bigdata-software]# nohup java -jar spt-test.jar &
[1] 3270
