[os] xx.serive文件编写 -- systemctl
一、 基本信息
1、 操作系统： Linux rocky 5.14.0-427.16.1.el9_4.x86_64 #1 SMP PREEMPT_DYNAMIC Wed May 8 17:48:14 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux
二、 c语言程序可运行文件（systest）
1、 源代码（systest.c）
1 [root@rocky:c]# cat systest.c
2 #include <stdio.h>
3 #include <stdlib.h>
4
5
6 void
7 msg
8 ()
9 {
10 printf("\n\t[lidawei]#\tsystemctl test\n\n");
11 }
12
13
14 int
15 main
16 ()
17 {
18 msg();
19
20 return 0;
21 }
2、 文件编译（systest.c）
[root@rocky:c]# gcc -o systest systest.c [root@rocky:c]# [root@rocky:c]# [root@rocky:c]# pwd /root/rocky93/lidawei/tmp/c [root@rocky:c]# [root@rocky:c]# [root@rocky:c]# ls asm_macro_bugs.c systest systest.c systest.service test test-as test.as test.c testcopy test.i test.s upper_lower upper_lower.c [root@rocky:c]# [root@rocky:c]#
三、 systest.service(position: /usr/lib/systemd/system)：
1、 文件的基本信息：
文件 文件位置
1） systest（elf） /root/rocky93/lidawei/tmp/c/systest
2） systest.service /usr/lib/systemd/system/systest.service
2、 systest.service 文件编写
[root@rocky:c]# cat systest.service # lidawei config -- date: 2024-05-22 # file_name = systest.service [Unit] Description=systemctl command test [Service] # running part: ExecStart ExecStart=/root/rocky93/lidawei/tmp/c/systest [Install] WantedBy=multi-user.target [root@rocky:c]# [root@rocky:c]#
3、 systest.service 文件放置： cp systest.service /usr/lib/systemd/system/systest.service
4、 systemctl enable systest.service 等效命令： ln -s /usr/lib/systemd/system/systest.service /etc/systemd/system/multi-user.target.wants/systest.service
5、 运行 systest.service : systemctl start systest.service
6、 查看 ‘5’ 的运行结果： systemctl status systest.service
[root@rocky:c]# systemctl start systest.service
[root@rocky:c]# systemctl status systest.service
○ systest.service - systemctl command test
Loaded: loaded (/usr/lib/systemd/system/systest.service; disabled; preset: disabled)
Active: inactive (dead)
May 22 23:02:59 rocky systemd[1]: Started systemctl command test.
May 22 23:02:59 rocky systest[2575]: [lidawei]# systemctl test
May 22 23:02:59 rocky systemd[1]: systest.service: Deactivated successfully.
[root@rocky:c]#
