關於 systemctl 的用法，大家自行百度

kbase-conference.service 的 demo 如下

[Unit]
Description=kbase-conference
After=network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
ExecStart=/home/ibotkbs/kbase-conference/startup.service.sh
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/home/ibotkbs/kbase-conference/shutdown.sh
PrivateTmp=true  
SuccessExitStatus=143    

[Install]  
WantedBy=multi-user.target
 

/home/ibotkbs/kbase-conference/startup.service.sh 檔案內容如下

#!/bin/sh
/home/ibotkbs/jdk1.8.0_151/bin/java -Xmn384M -Xmx1024M -Xms1024M -Xss256k -jar /home/ibotkbs/kbase-conference/kbase-conference-0.0.1-SNAPSHOT.jar -java.io.tmpdir=/home/ibotkbs/tmp --spring.config.location=/home/ibotkbs/kbase-conference/config/application.properties --spring.profiles.active=dev > /home/ibotkbs/kbase-conference/logs/stdout.log &
 

/home/ibotkbs/kbase-conference/shutdown.sh 檔案內容如下：

#!/bin/sh
kill -9 `ps -ef|grep java|grep -v grep|grep kbase-conference|awk '{print $2}'`

注意事項

1、spring boot 這裡主要遇到的問題是配置檔案的指定，主要加上下面這句，就可以讀到配置

--spring.config.location=/home/ibotkbs/kbase-conference/config/application.properties

2、startup.sh 中一定要用守護程序，否則 systemctl start 超過 90 秒會自動停掉，有一個超時的報錯

[[email protected] ~]# systemctl status kbase-conference.service
