英文:
Spring Boot app fails to start up using SSH
问题
我有一个在staging和prod服务器上正常运行的Spring应用程序。现在是时候自动化部署了。
我在我的staging服务器上有一个restart.sh脚本。如果我作为用户通过SSH登录服务器并运行它，一切正常。
运行命令：nohup ./restart.sh
# restart.sh
kill $(ps -aux | grep plenti-app | grep java | awk '{print $2}')
java -jar -Dspring.profiles.active=staging plenti-app
然而，当我尝试通过SSH运行命令时，它失败并显示数据库密码验证失败。
ssh user@$STAGING_IP "./restart.sh"
org.postgresql.util.PSQLException: FATAL: password authentication failed for user "gszbybjk"
at org.postgresql.core.v3.ConnectionFactoryImpl.doAuthentication(ConnectionFactoryImpl.java:520) ~[postgresql-42.2.9.jar!/:42.2.9]
我最初怀疑这可能与环境变量有关，因为我是通过环境变量存储数据库凭据的，但是对ssh user@ip echo $DB_PASSWORD的调用返回了预期的值。
英文:
I have a spring app that is happily running on a staging and a prod server. It's time to automate deployments.
I have a restart.sh script on my staging server. if I ssh into the server and run it as a user everything works as expected.
command to run: nohup ./restart.sh
# restart.sh
kill $(ps -aux | grep plenti-app | grep java | awk '{print $2}')
java -jar -Dspring.profiles.active=staging plenti-app
However, when I attempt to run the command through ssh, it fails saying that password authentication for my database fails.
ssh user@$STAGING_IP "./restart.sh"
org.postgresql.util.PSQLException: FATAL: password authentication failed for user "gszbybjk"
at org.postgresql.core.v3.ConnectionFactoryImpl.doAuthentication(ConnectionFactoryImpl.java:520) ~[postgresql-42.2.9.jar!/:42.2.9]
I first suspected that this might have to do with environment variables since that's how I'm storing the database credentials, but ssh calls to ssh user@ip echo $DB_PASSWORD result in the expected value.

结果证明，我走错了方向。有一个完整的子系统专门用于启动服务应用，称为 systemd。

Turns out, I was going about this the wrong way. There's a whole subsystem dedicated to launching service applications called systemd
