1、root下，vi /etc/sudoers :

[root@guanz etc]# vi /etc/sudoers
[root@guanz etc]# 

# 添加如下內(nèi)容:
guanz    ALL=(ALL)       ALL

示例:
##
## Allow root to run any commands anywhere
root    ALL=(ALL)       ALL
guanz    ALL=(ALL)       ALL
## Allows members of the 'sys' group to run networking, software,

2、切換至普通用戶guanz,并測試命令:

2.1 方式一：【echo 'passwd' | sudo -S java -jar ****】

[root@guanz etc]# su guanz
[guanz@guanz etc]$ 

# 進(jìn)入jar包所在目錄下：
[guanz@guanz dell]$ cd app/
[guanz@guanz app]$ ll
total 599948
-rw-rw-r--. 1 guanz guanz     59162 Jul  1 11:09 log-210701-01.txt
-rwxrwxr-x. 1 guanz guanz 307142072 Jul  1 14:36 test-1.0.jar

# 查看當(dāng)前在運行的窗口程序
[guanz@guanz app]$ screen -ls
No Sockets found in /var/run/screen/S-guanz.

# 創(chuàng)建窗口腺律，并進(jìn)入，直接執(zhí)行java -jar啟動宜肉，會提示你輸入密碼：
[guanz@guanz app]$ screen -S jar
[guanz@guanz app]$ sudo java -jar test-1.0.jar > log-01.txt
[sudo] password for guanz: 

# 通過【echo 'passwd' | sudo -S java -jar ****】再次執(zhí)行匀钧，會直接啟動，無需再輸入密碼谬返。
[guanz@guanz app]$ echo '123456' | sudo -S java -jar test-1.0.jar > log-01.txt
[sudo] password for guanz: 


# 查看當(dāng)前在運行的窗口
[guanz@guanz app]$ screen -ls
There is a screen on:
    17362.jar   (Detached)
1 Socket in /var/run/screen/S-guanz.
[guanz@guanz app]$ 


# 查看日志文件之斯，發(fā)現(xiàn)文件已啟動：
2021-07-01 15:01:02.531  INFO 17548 --- [           main] o.s.b.w.embedded.tomcat.TomcatWebServer  : Tomcat started on port(s): 8890 (http) with context path ''
2021-07-01 15:01:02.534  INFO 17548 --- [           main] com.example.demo.DemoApplication         : Started DemoApplication in 29.065 seconds (JVM running for 30.46)

至此，此命令有效遣铝。

2.2 方式二：【EOF】文本塊方式

sudo -S java -jar test-1.0.jar > log-01.txt << EOF 
> passwd
> EOF

# 通過【EOF】文本塊的方式佑刷，再次執(zhí)行，會直接啟動酿炸，無需再輸入密碼瘫絮。
[guanz@guanz app]$ sudo -S java -jar test-1.0.jar > log-01.txt << EOF
> 123456
> EOF



# 查看日志文件，發(fā)現(xiàn)文件已啟動：
2021-07-01 15:04:39.160  INFO 17848 --- [           main] o.s.b.w.embedded.tomcat.TomcatWebServer  : Tomcat started on port(s): 8890 (http) with context path ''
2021-07-01 15:04:39.162  INFO 17848 --- [           main] com.example.demo.DemoApplication         : Started DemoApplication in 29.111 seconds (JVM running for 30.618)


至此填硕，此命令有效麦萤。

3、自啟動.sh腳本文件:

#!/bin/bash
#cd ~/app
#sudo java -jar test-1.0.jar > log.txt

screen_name=$"jar"
screen -dmS $screen_name
cmd1=$"cd /home/app";
screen -x -S $screen_name -p 0 -X stuff "$cmd1"
screen -x -S $screen_name -p 0 -X stuff $'\n'
cmd3=$"echo '123456' | sudo -S java -jar test-1.0.jar > log-01.txt";
screen -x -S $screen_name -p 0 -X stuff "$cmd3"
screen -x -S $screen_name -p 0 -X stuff $'\n'
cmd4=$"screen -d jar";
screen -x -S $screen_name -p 0 -X stuff "$cmd4"
screen -x -S $screen_name -p 0 -X stuff $'\n'

日志文件按照當(dāng)天日期存儲：

#!/bin/bash
#cd ~/app
#sudo java -jar test-1.0.jar > log.txt
currentdate=$(date +%Y%m%d)
logdatefile="log-"$currentdate".txt"

screen_name=$"jar"
screen -dmS $screen_name
cmd1=$"cd /home/app";
screen -x -S $screen_name -p 0 -X stuff "$cmd1"
screen -x -S $screen_name -p 0 -X stuff $'\n'
cmd3=$"echo '123456' | sudo -S java -jar test-1.0.jar >  $logdatefile";
screen -x -S $screen_name -p 0 -X stuff "$cmd3"
screen -x -S $screen_name -p 0 -X stuff $'\n'
cmd4=$"screen -d jar";
screen -x -S $screen_name -p 0 -X stuff "$cmd4"
screen -x -S $screen_name -p 0 -X stuff $'\n'

再見扁眯。
