1. 使用systemd优雅启停应用

  1. 添加依赖

    pom.xm的build.plugins节点
    <plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <configuration>
        <executable>true</executable>
    </configuration>
</plugin>

  2. 添加服务

    /etc/systemd/system/myapp.service
    [Unit]
Description=myapp
After=syslog.target

[Service]
User=root
ExecStart=/var/myapp/myapp.jar
SuccessExitStatus=143

[Install]
WantedBy=multi-user.target

  3. 配置 在jar包同目录下增加同名配置文件

    myapp.conf
    JAVA_OPTS="-server -Xms100m -Xmx300m -Xmn128m -Xss256k"

  4. 启停

    systemctl enable myapp # 开机自启动
systemctl status|start|stop|restart myapp
journalctl -u myapp # 看日志，shift+g跳转到最后一行
