修改服务配置文件postgresql.conf中的监听参数

默认配置文件在PGDATA目录下(除了你是通过服务进程中的参数config_file来指定的)

[[email protected] data]$ vi postgresql.conf
......
listen_addresses = ‘*‘                  # what IP address(es) to listen on;
......

修改pg_hba.conf文件,添加一行host认证

默认配置文件在PGDATA目录中,可以通过服务配置文件 postgresql.conf中hba_file参数来修改到其他位置

[[email protected] data]$ vi pg_hba.conf
......
host    all             all             192.168.10.0/24         md5
......

192.168.10.0/24是我的客户机所在网段

重启生效一下

[[email protected] data]$ pg_ctl restart -l /var/lib/pgsql/pgsql.log
