[root@centos8 yum.repos.d]# yum install postgresql-server
Package postgresql-server-10.15-1.module_el8.3.0+619+dbc95fbc.x86_64 is already installed.
[root@centos8 yum.repos.d]# dnf install postgresql-server
Package postgresql-server-10.15-1.module_el8.3.0+619+dbc95fbc.x86_64 is already installed.
[root@centos8 yum.repos.d]# systemctl restart postgresql.service

查看postgresql 版本

[postgres@centos8 ~]$ psql --version
psql: /lib/libpq.so.5: no version information available (required by psql)

1，修改文件 /var/lib/pgsql/data/pg_hba.conf

[root@centos8 data]# vim /var/lib/pgsql/data/pg_hba.conf

host    all       all         192.168.1.1/32      md5 --/32代表只允许192.168.1.1访问
host    all       all         192.168.1.0/24     md5 --/24代表192.168.1.1~192.168.1.255都允许访问
host    all       all         192.168.0.0/16      md5 --/16代表192.168.1.1~192.168.255.255都允许访问
host    all       all         192.0.0.0/8          md5 --/8代表192.1.1.1~192.255.255.255都允许访问
host    all       all         0.0.0.0/0          md5 --/0代表所有ip地址都允许访问
找到“# IPv4 local connections:“后，新加一行内容如下：
host    all       all         0.0.0.0/0          trust
2，修改文件 /var/lib/pgsql/data/postgresql.conf
修改内容 listen_addresses = '*'
3，重启postgres服务
[root@centos8 data]# systemctl restart postgresql.service
[root@centos8 data]# systemctl status postgresql.service
4，防火墙打开端口，以CentOS8为例
[root@centos8 data]# sudo firewall-cmd --permanent --zone=public --add-port=5432/tcp
[root@centos8 data]# sudo firewall-cmd --reload

[root@centos8 pgsql]# vim /var/lib/pgsql/initdb_postgresql.log 

[root@centos8 pgsql]# vim initdb_postgresql.log

The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

The database cluster will be initialized with locale "en_US.UTF-8".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".

Data page checksums are disabled.

fixing permissions on existing directory /var/lib/pgsql/data ... ok

Success. You can now start the database server using:
