ruby-on-rails - 停止 postgres 进程重新启动 - mac

Question

我正在尝试运行我的 Rails 项目，但它一直在下降，因为它依赖于运行的 postgres。当我尝试启动 postgres 时，它一直说它已经在运行(或端口已被占用)。我检查了事件监视器，有大约 6 个 postgres 进程在运行，当我尝试终止/强制退出进程时，它们再次出现...

不确定如何解决这个问题。

运行 postgres -D/usr/local/var/postgres 时的实际错误:

LOG: could not bind IPv6 socket: Address already in use HINT: Is another postmaster already running on port 5432? If not, wait a few seconds and retry. LOG: could not bind IPv4 socket: Address already in use HINT: Is another postmaster already running on port 5432? If not, wait a few seconds and retry. WARNING: could not create listen socket for "localhost" FATAL: could not create any TCP/IP sockets

当我尝试使用 pg_ctl -D/usr/local/var/postgres stop -s -m fast 停止 postgres 时，我收到此错误:

pg_ctl: PID file "/usr/local/var/postgres/postmaster.pid" does not exist Is server running?

Answer 1

我最终从头开始:

• 通过自制软件卸载 postgres (brew uninstall postgresql)
• 通过卸载程序卸载 postgres (/Library/Postgresql/version/uninstall)
• 通过文件系统删除postgres(删除文件夹:/Library/Postgresql/)

然后只需进行自制软件安装:

brew install postgresql

并手动启动 postgres。
