編譯安裝

編譯參數

$ ./configure \
--prefix=/usr/local/pgsql \
--datadir=/var/pg \
--enable-thread-safety \
--with-gssapi \
--with-krb5 \
--with-ldap \
--with-openssl \
--with-libxml \
--with-libxslt \
--without-readline > out

安裝

$ make > out
$ make install

ln -s /usr/local/pgsql/bin/pg_ctl /usr/local/bin

初始化數據庫

$ su postgres

$ /usr/local/pgsql/bin/initdb -E UNICODE -D /var/pg/data

啓動數據庫

$ pg_ctl start -D /var/pg/data/ -l /var/pg/log/serverlog

設置遠程鏈接

$ vim /var/pg/data/pg_hba.conf

修改以下：

# IPv4 local connections:
host    all             all             127.0.0.1/32            trust
host    all             all             0.0.0.0/0               trust

$ vim /var/pg/data/postgresql.conf

找到：

#listen_addresses = 'localhost'

修改以下：

listen_addresses = '*'

重啓

pg_ctl restart -D /var/pg/data/ -l /var/pg/log/serverlog
