我有一个在使用 PostgreSQL 的 Ubuntu 服务器上运行的应用程序。
我可以从项目目录运行应用程序的可执行文件(作为非 root 用户)。
我已经为此应用程序创建了一个服务 ( /etc/systemd/system/cineapi.service
),以便它在重新启动时自动启动。该文件的内容是:
[Unit]
Description=cineapi
[Service]
Type=simple
Restart=on-failure
RestartSec=5s
WorkingDirectory=/home/saurabh/projects/cineapi
ExecStart=/home/saurabh/projects/cineapi/cineapi.o
[Install]
WantedBy=multi-user.target
当重新加载系统守护程序并启动服务时,如下所示:
sudo systemctl daemon-reload
sudo service cineapi start
我收到错误:
pq: password authentication failed for user "root"
我不明白为什么会发生这种情况。我没有在应用程序的任何地方使用“root”用户。它的.env
文件看起来像
postgres://goapi:somepassword@MY_IPV4_ADDR:DB_PORT/cineapi
并在启动时获取。我还进行了以下更改:
/etc/postgresql/16/main/postgresql.conf
password_encryption = scram-sha-256
/etc/postgresql/16/main/pg_hba.conf
host cineapi goapi MY_IPV4_ADDR scram-sha-256

执行二进制文件时 Postgres 记录:
