    怎么才能进入postgresql数据库

    silencementsilencement2020-03-12 16:53:29原创3564

    启动数据库服务器(posgres用户):

    1

    2

    [postgres@localhost bin]$ postgres -D /opt/postgresql/data/ > /opt/postgresql/log/pg_server.log 2>&1 &

    [1] 4508

    当然如果设置了环境变量

    1

    2

    PGDATA=/opt/postgresql/data

    export PGDATA

    后,可使用pg_ctl工具进行启动:

    1

    2

    3

    4

    5

    [postgres@localhost log]$ pg_ctl start -l /opt/postgresql/log/pg_server.log

    pg_ctl: another server might be running; trying to start server anyway

    pg_ctl: could not start server

    Examine the log output.

    [postgres@localhost log]$

    当然,最简的启动方式是:

    1

    2

    3

    4

    5

    [postgres@localhost ~]$ pg_ctl start

    server starting

    [postgres@localhost ~]$ LOG:  database system was shut down at 2011-07-09 13:58:00 CST

    LOG:  autovacuum launcher started

    LOG:  database system is ready to accept connections

    如果要在操作系统启动时就启动PG,可以在/etc/rc.d/rc.local 文件中加以下语句:

    1

    /opt/postgresql/bin/pg_ctl start -l /opt/postgresql/log/pg_server.log -D /opt/postgresql/data
