postgresql數據庫設置遠程登陸賬戶和密碼
1.本地登陸postgresql,建庫授權，設置密碼
服務器本地登陸postgresql數據庫（默認是不需要密碼的）
[email protected] ~]$ psql
psql.bin (9.5.9)
Type "help" for help.
創建角色，並且給角色設置密碼:
postgres=# create user testwjw with password ‘[email protected]&^%996‘;
CREATE ROLE
修改數據庫用戶和密碼：
postgres=# alter user testwjw with password ‘558996‘;
ALTER ROLE
指定字符集創建數據庫testdb1，並且授權給testwjw
postgres=# create database testdb1 with encoding=‘utf8‘ owner=testwjw;
CREATE DATABASE
授權：
postgres=# grant all privileges on database testdb1 to testwjw;
GRANT
2.修改postgresql.conf文件中的端口和監聽主機:
postsql默認安裝後是監聽本機127.0.0.1 默認端口是5432,是不能夠遠程登陸的，所以要修改監聽主機地址，同時修改默認的端口為:36985
postgresql數據庫的配置文件是:postgresql.conf,所在位置是：postgresql初始化時所指定的data數據目錄下：
[[email protected] ~]$ ll /data/postgresql/data/postgresql.conf
-rw------- 1 postgres postgres 21305 Oct 3 11:18 /data/postgresql/data/postgresql.conf
[[email protected] ~]$ egrep "listen_addresses|5432"/data/postgresql/data/postgresql.conf
listen_addresses = ‘localhost‘# what IP address(es) to listen on;
port = 5432# (change requires restart)
修改監聽主機為*，端口為:36985
[[email protected] ~]$ egrep "listen_addresses|36985" /data/postgresql/data/postgresql.conf
listen_addresses = ‘*‘# what IP address(es) to listen on;
port = 36985# (change requires restart)
修改配置文件pg_hba.conf ，允許遠程ip訪問本地數據庫，以及設置服務器本地登陸postgresql數據庫要求輸入密碼才可以登陸
[[email protected] ~]$ egrep "60.223.153.25|127.0.0.1" /data/postgresql/data/pg_hba.conf
host all all 60.223.153.25/32 trust
host all all 127.0.0.1/32 password
#host replication postgres 127.0.0.1/32 trust
3.重啟postgresql服務生效：
[[email protected] ~]$ pg_ctl -D /data/postgresql/data -l /data/postgresql/log/postgres.log restart
waiting for server to shut down....LOG: received fast shutdown request
LOG: aborting any active transactions
LOG: autovacuum launcher shutting down
LOG: shutting down
LOG: database system is shut down
done
server stopped
server starting
[[email protected] ~]$ netstat -lntup|grep postgres
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
tcp 0 0 0.0.0.0:36985 0.0.0.0:* LISTEN 6472/postgres
4.登陸數據庫:
[[email protected] ~]$ psql
psql.bin: 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"?
[[email protected] ~]$ psql -Utestwjw -dpostgres -p36985 -h 127.0.0.1
Password for user testwjw:
psql.bin: fe_sendauth: no password supplied
[[email protected] ~]$ psql -Utestwjw -dpostgres -p36985 -h 127.0.0.1
Password for user testwjw:
psql.bin (9.5.9)
Type "help" for help.
postgres=> \q
[[email protected] ~]$ psql -Utestwjw -dtestdb1 -p36985 -h 127.0.0.1
Password for user testwjw:
psql.bin (9.5.9)
Type "help" for help.
testdb1=> select * from t;
id | nan | note
----+-----+-------
1 | t | TRUE
2 | f | FALSE
3 | t | tRue
4 | f | fAlse
11 | | null
11 | | NULL
7 | t | ‘t‘
8 | f | ‘f‘
9 | t | ‘yes‘
10 | f | ‘0‘
(10 rows)
testdb1=>
[[email protected] ~]$ psql -Utestwjw -dtestdb1 -p36985
psql.bin (9.5.9)
Type "help" for help.
testdb1=> \q
[[email protected] ~]$ psql -Utestwjw -dtestdb2 -p36985
psql.bin (9.5.9)
Type "help" for help.
testdb2=> \q
