我正在使用 Linux Mint 17。我使用 apt-get 安装了 postgres。我有 postgres 用户帐户,我不必创建它。然后我以 postgres 身份登录并按照以下步骤操作:
$ initdb -D /usr/local/pgsql/data
...
Success.
You can now start the database server of the Postgres-XC coordinator using:
postgres --coordinator -D /usr/local/pgsql/data
or
pg_ctl start -D /usr/local/pgsql/data -Z coordinator -l logfile
You can now start the database server of the Postgres-XC datanode using:
postgres --datanode -D /usr/local/pgsql/data
or
pg_ctl start -D /usr/local/pgsql/data -Z datanode -l logfile
然后我发出了这两个命令:
$ pg_ctl start -D /usr/local/pgsql/data -Z coordinator -l logfile
$ pg_ctl start -D /usr/local/pgsql/data -Z datanode -l logfile
我没有得到任何回应。
然后我尝试了 createdb 和 createuser 但我不能。她你可以看到一些信息,我希望它有帮助。
