问题描述

我正在尝试在我的本地机器上启动我的 Postgresql 开发实例。我正在使用 WSL Ubuntu 18.04.4 LTS 运行 Windows 10 Home(内部版本 18363.900)。我尝试了很多事情:

$ sudo systemctl start postgresql
System has not been booted with systemd as init system (PID 1). Can't operate.

(与重启相同)

$ sudo /etc/init.d/postgresql start
 * Starting PostgreSQL 10 database server                                                          * Error: /usr/lib/postgresql/10/bin/pg_ctl /usr/lib/postgresql/10/bin/pg_ctl start -D /var/lib/postgresql/10/main -l /var/log/postgresql/postgresql-10-main.log -s -o  -c config_file="/etc/postgresql/10/main/postgresql.conf"  exited with status 1:

2020-06-16 20:36:37.335 PDT [8106] LOG:  database system is shut down
pg_ctl: could not start server
Examine the log output.

(同样适用于 postgres)

$ sudo service postgresql start
 * Starting PostgreSQL 10 database server                                                          * Error: /usr/lib/postgresql/10/bin/pg_ctl /usr/lib/postgresql/10/bin/pg_ctl start -D /var/lib/postgresql/10/main -l /var/log/postgresql/postgresql-10-main.log -s -o  -c config_file="/etc/postgresql/10/main/postgresql.conf"  exited with status 1:
2020-06-16 20:37:19.907 PDT [8140] LOG:  could not bind IPv4 address "127.0.0.1": Permission denied
2020-06-16 20:37:19.907 PDT [8140] HINT:  Is another postmaster already running on port 5432? If not, wait a few seconds and retry.

以防万一

$ sudo service postgres start
postgres: unrecognized service

服务对我没有好处。

当然,停止按预期工作:

$ sudo service postgresql stop
 * Stopping PostgreSQL 10 database server                                                  [ OK ]

sudo service postgresql restart

与开始相同。

状态也给了我一个预期的结果:

$ sudo service postgresql status
10/main (port 5432): down

我的 /etc/hosts 读取

# This file is automatically generated by WSL based on the Windows hosts file:
# %WINDIR%\System32\drivers\etc\hosts. Modifications to this file will be overwritten.
127.0.0.1       localhost
127.0.1.1       DESKTOP-LKMEB17.localdomain     DESKTOP-LKMEB17

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

这使我相信对 /etc/hosts 的更改无济于事

我试图杀死 postmaster,但每次我试图杀死它时它的 pid 都会不断变化,这让我相信它在旋转

$ ps -ef | grep postmaster | awk '{print $2}'
8151
$ ps -ef | grep postmaster | awk '{print $2}'
8154

在黑暗中射击以杀死进程也不起作用,令人困惑

$ ps -ef | grep postmaster
me       298   116  0 15:35 tty3     00:00:00 grep postmaster
$ kill -9 300
-bash: kill: (300) - No such process
$ kill -9 298
-bash: kill: (298) - No such process
$ kill -9 299
-bash: kill: (299) - No such process
$ kill -9 301
-bash: kill: (301) - No such process
$ ps -ef | grep postmaster
me       300   116  0 15:36 tty3     00:00:00 grep postmaster

这很奇怪——我杀死了 pid 300

令人惊讶的是,localhost:5432 上似乎没有任何东西在听

$ curl localhost:5432
curl: (52) Empty reply from server

我不知道从这里去哪里。

解决方案


为什么不能使用 systemd 的答案很简单:WSL 从第 1 天到现在都不支持它。这是一个已知问题,您可以参考2018 年打开的这个问题和使用 Windows 的类似配置的这个问题和 WSL了解更多信息。

postgresql 的问题是另一个已知问题。它已在 WSL 2 中修复。为了解决 WSL 1 上的这个问题,这篇文章告诉您设置fsync=ondata_sync_retry=true. 解决问题的另一种方法是设置fsync=off. 有关 WSL 中 fsync 问题的更多信息,请参阅此问题。
