无法在 ubuntu 上安装 postgresql 10

Question

我正在执行此命令以在我的 ubuntu 14.04 中安装 postgesql

sudo apt-get install postgresql postgresql-contrib

我在安装过程中遇到错误：

Failed to issue method call: Unit postgresql@10-main.service failed to load: No such file or directory. See system logs and 'systemctl status postgresql@10-main.service' for details

这是完整的日志：

This user must also own the server process.

The database cluster will be initialized with locale "en_IN".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".

Success. You can now start the database server using:

    /usr/lib/postgresql/10/bin/pg_ctl -D /var/lib/postgresql/10/main -l logfile start

这是输出 systemctl status postgresql@10-main.service

Answer 1

postgresql-fails-to-reinstall-after-upgrading-ubuntu-12-04-to-14-04 中接受的答案对我有用。

为了便于参考，我粘贴了以下链接中的说明：

检查/etc/init.d/postgresql它使用的文件/usr/share/postgresql-common/init.d-functions。执行此文件/usr/bin/pg_ctlcluster以启动和停止 postgresql 服务器。

if [ "$1" = "stop" ] || [ "$1" = "restart" ]; then
    ERRMSG=$(pg_ctlcluster --force "$2" "$name" $1 2>&1)
else
    ERRMSG=$(pg_ctlcluster "$2" "$name" $1 2>&1)
fi

/usr/bin/pg_ctlclusterfile 接受--skip-systemctl-redirect在没有 systemctl 的情况下启动或停止 postgresql 的选项。所以，你需要添加--skip-systemctl-redirect中/usr/share/postgresql-common/init.d-functions的do_ctl_all()功能。所以它看起来像这样。

if [ "$1" = "stop" ] || [ "$1" = "restart" ]; then
    ERRMSG=$(pg_ctlcluster --skip-systemctl-redirect --force "$2" "$name" $1 2>&1)
else
    ERRMSG=$(pg_ctlcluster --skip-systemctl-redirect "$2" "$name" $1 2>&1)
fi

或者您可以$skip_systemctl_redirect = 1;在$skip_systemctl_redirect签入之前添加/usr/bin/pg_ctlcluster。
