postgresql学习-Part1-创新互联

1. 错误, 允许本地连接:
-bash-4.1$ psql mydb
psql: FATAL:  no pg_hba.conf entry for host "[local]", user "postgres", database "mydb", SSL off
在配置文件:pg_hba.conf增加如下内容
# IPv4 local connections:
#允许本地连接
local   all         all                               trust
#允许远程连接
host    all         all         0.0.0.0/0             md5
2. 推出psql命令行
 \q
 mydb-# \q
-bash-4.1$
3. 类似于oracle sqlplus
mydb=# select version();
                                                      version
-------------------------------------------------------------------------------------------------------------------
 PostgreSQL 8.4.20 on x86_64-redhat-linux-gnu, compiled by GCC gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-17), 64-bit
(1 row)
mydb=# select current_date;
    date
