linux后台启动springboot并指定日志文件名称

如果用nohup启动jar包的话，默认的日志文件就是nohup.out，那么如果启动多个jar包的话，看日志文件就麻烦了，因为他们都会写入到nohup.out文件中。

所以我们来指定一下不同jar包的日志文件名：

[ ~]$ mkdir log
[ ~]$ nohup java -jar dianyixia-0.0.1-SNAPSHOT.jar > log/dianyixia.log &
[1] 5861
[ ~]$ nohup: ignoring input and redirecting stderr to stdout

看一眼，日志确实写入到dianyixia.log文件中了：

[ ~]$ cat log/dianyixia.log

如法炮制，再来一个：

[ ~]$ nohup java -jar prize-0.0.1-SNAPSHOT.jar > log/prize.log &
[2] 6306
[ ~]$ nohup: ignoring input and redirecting stderr to stdout

看看

[ ~]$ tail -f log/prize.log
