我有 postgres 服务器在我的机器上本地运行。更新并重新启动后,我似乎无法运行它。
$ psql
psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
$ pg_ctl start -D /Library/PostgreSQL/9.1/data/
pg_ctl: could not open PID file "/Library/PostgreSQL/9.1/data/postmaster.pid": Permission denied
$ sudo ls /Library/PostgreSQL/9.1/data/
PG_VERSION global pg_hba.conf pg_log pg_notify pg_stat_tmp pg_tblspc pg_xlog postmaster.opts
base pg_clog pg_ident.conf pg_multixact pg_serial pg_subtrans pg_twophase postgresql.conf postmaster.pid
显然服务器正在运行。
$ ps aux | grep postmaster
postgres 63 0.0 0.0 2480820 7320 ?? Ss 4:39PM 0:00.27 /Library/PostgreSQL/9.1/bin/postmaster -D/Library/PostgreSQL/9.1/data
xxxxx 636 0.0 0.0 2435116 524 s000 R+ 5:22PM 0:00.00 grep postmaster
我不是 data/ 的所有者,postgres 是:
$ ls -alth /Library/PostgreSQL/9.1/data/
ls: : Permission denied
$ sudo ls -alth /Library/PostgreSQL/9.1/data/
