u run initdb.
Success. You can now start the database server using:
pg_ctl -D /usr/local/pgsql-10.5/data -l logfile start
[postgres@web1 ~]$
***在此就已经部署成功了，现在要做的就是修改下配置文件，优化下***
17、前往文件安装所在地，修改pg_hba.conf配置文件
[postgres@web1 data]$ cp pg_hba.conf pg_hba.conf.`date +%F`
[postgres@web1 data]$ vim pg_hba.conf
