PostgreSQL installation experience

2019 Unicorn Enterprises heavily recruiting engineers Python standard >>>

Today started to use their leisure time to learn PGSQL. Below I posted my initial installation experience.
1, encountered two errors:
  1), the configure: error: Library not found readline
  Solution:
  install libtermcap-devel-2.0.8-46.1.i386.rpm
  and readline-devel-5.1-1.1.i386.rpm
  installation process not to say.
  for inflate in -lz ... Checking NO
  2), the configure: error: Library zlib not found 
  the solution:
  install zlib-devel-1.2.3-3.i386.rpm
  then ./configurate;make;make install
  if to this further says that the installation was successful.
  Complete Installation the PostgreSQL.
 The PGSQL successful installation
2, a subsequent set
[the root @localhost pgSQL] # the make the dir / usr / local / pgSQL / Data
PostGRE ROOT does not seem to be operated. Only ordinary users.
[root @localhost pgsql]# adduser postgres
[root @localhost pgsql]# chown -R postgres /usr/local/pgsql/data/
初始化数据库：
[root @localhost pgsql]# su postgres
[postgres @localhost pgsql]$ ./bin/initdb -D /usr/local/pgsql/data/
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.
