Spring Boot应用程序即服务 [英] Spring Boot application as a Service
问题描述
如何在Linux系统中很好地配置打包为可执行jar作为服务的Spring Boot应用程序?是推荐的方法，还是应该将此应用转换为war并将其安装到Tomcat中?
How to configure nicely Spring Boot application packaged as executable jar as a Service in the Linux system? Is this recommended approach, or should I convert this app to war and install it into Tomcat?
当前，我可以从 screen 会话运行Spring引导应用程序，这很好，但是需要在服务器重启后手动启动.
Currently, I can run Spring boot application from the screen session, which is nice but requires manual start after a server reboot.
如果我使用可执行文件 jar 的方法是正确的，我正在寻找的是一般建议/指导或示例 init.d 脚本.
What I'm looking for is general advice/direction or sample init.d the script, if my approach with executable jar is proper.
推荐答案
以下内容适用于springboot 1.3及更高版本:
The following works for springboot 1.3 and above:
作为init.d服务
可执行jar具有通常的启动，停止，重新启动和状态命令.还将在通常的/var/run目录中设置PID文件，并默认登录在通常的/var/log目录中.
The executable jar has the usual start, stop, restart, and status commands. It will also set up a PID file in the usual /var/run directory and logging in the usual /var/log directory by default.
您只需要像这样将jar符号链接到/etc/init.d中
You just need to symlink your jar into /etc/init.d like so
sudo link -s /var/myapp/myapp.jar /etc/init.d/myapp
OR
sudo ln -s ~/myproject/build/libs/myapp-1.0.jar /etc/init.d/myapp_servicename
之后就可以正常操作了
/etc/init.d/myapp start
然后，如果需要，可以在您希望应用在启动时启动/停止的任何运行级别中设置一个链接.
Then setup a link in whichever runlevel you want the app to start/stop in on boot if so desired.
作为系统服务
要运行安装在var/myapp中的Spring Boot应用程序，可以在/etc/systemd/system/myapp.service中添加以下脚本:
To run a Spring Boot application installed in var/myapp you can add the following script in /etc/systemd/system/myapp.service:
[Unit]
Description=myapp
After=syslog.target
[Service]
ExecStart=/var/myapp/myapp.jar
[Install]
WantedBy=multi-user.target
注意:如果您正在使用此方法，请不要忘记使jar文件本身可执行(使用chmod + x)，否则它将因错误权限被拒绝"而失败.
NB: in case you are using this method, do not forget to make the jar file itself executable (with chmod +x) otherwise it will fail with error "Permission denied".
