安装后，服务已启动，查看装到了哪儿：
[root@com4 network-scripts]# ps -ef | grep postgres postgres 1708 1 0 04:22 ? 00:00:00 /opt/Postgresql/9.1/bin/postgres -D /opt/Postgresql/9.1/data postgres 1709 1708 0 04:22 ? 00:00:00 postgres: logger process postgres 1711 1708 0 04:22 ? 00:00:00 postgres: writer process postgres 1712 1708 0 04:22 ? 00:00:00 postgres: wal writer process postgres 1713 1708 0 04:22 ? 00:00:00 postgres: autovacuum launcher process postgres 1714 1708 0 04:22 ? 00:00:00 postgres: stats collector process root 3400 2547 0 04:31 pts/0 00:00:00 grep postgres
找到psql文件，登录，若嫌麻烦可将安装目录加入Path:
[root@com4 network-scripts]# psql bash: psql: command not found [root@com4 network-scripts]# su postgres bash-4.1$ psql bash: psql: command not found bash-4.1$ /opt/Postgresql/9.1/bin/psql Password: psql.bin (9.1.1) Type "help" for help. postgres=# \d No relations found. postgres=# \t Showing only tuples. postgres=# \l postgres | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | template0 | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/postgres + | | | | | postgres=CTc/postgres template1 | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/postgres + | | | | | postgres=CTc/postgres postgres=# \c postgres You are Now connected to database "postgres" as user "postgres". postgres=# \d No relations found.
允许远程连接：
修改pg_hba.conf 文件，在 “host all all 127.0.0.1/32 md5”下面添加一行：
host all all 192.168.1.106/24 md5
修改postgresql.conf 文件，在#standard_conforming_strings = on 下添加一行：
standard_conforming_strings = off
有的版本还需要检查postgresql.conf文件中监听地址是否能监听客户端：
listen_addresses = '*' # what IP address(es) to listen on;
重启：
[root@com4 Desktop]# /etc/init.d/postgresql-9.1 status pg_ctl: server is running (PID: 1708) /opt/Postgresql/9.1/bin/postgres "-D" "/opt/Postgresql/9.1/data" [root@com4 data]# /etc/init.d/postgresql-9.1 restart
关闭开机自动启动：
[yuming@com4 Desktop]$ runlevel N 5 [root@com4 Desktop]# chkconfig --level 5 postgresql-9.1 off
关闭防火墙，进行远程连接：
[root@indigo apache]# psql -h 192.168.1.109 -p 5432 -U postgres -W pg -d postgres psql: warning: extra command-line argument "pg" ignored Password for user postgres: psql (9.2.4,server 9.1.1) WARNING: psql version 9.2,server version 9.1.
