Ubuntu 9.10下PostgreSQL 8.4忘記密碼的解決方法

Ubuntu 9.10下PostgreSQL 8.4忘記密碼的解決方法:

1.

編輯pg_hba.conf中的

83 # IPv4 local connections:
84 host    all         all         127.0.0.1/32          trust
-
 

mickey@pentest:/etc/postgresql/8.4/main$ sudo vim pg_hba.conf
mickey@pentest:/etc/postgresql/8.4/main$ sudo /etc/init.d/postgresql-8.4 restart
* Restarting PostgreSQL 8.4 database server                                              [ OK ]

2.

mickey@pentest:~$ psql -h 127.0.0.1 -U postgres
psql (8.4.2)
SSL connection (cipher: DHE-RSA-AES256-SHA, bits: 256)
Type “help” for help.
postgres=# ALTER USER postgres WITH PASSWORD ‘mickey’;
ALTER ROLE
postgres=# \q

3.

將pg_hba.conf中的該回

83 # IPv4 local connections:
84 host    all         all         127.0.0.1/32          md5

mickey@pentest:/etc/postgresql/8.4/main$ sudo vim pg_hba.conf
mickey@pentest:/etc/postgresql/8.4/main$ sudo /etc/init.d/postgresql-8.4 restart
* Restarting PostgreSQL 8.4 database server                                              [ OK ]
