開始編譯安裝三把斧

$ ./configure --help
`configure' configures PostgreSQL 9.6.9 to adapt to many kinds of systems.

Usage: ./configure [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help display this help and exit       --help=short display options specific to this package       --help=recursive display the short help of all the included packages   -V, --version display version information and exit   -q, --quiet, --silent do not print `checking ...' messages       --cache-file=FILE cache test results in FILE [disabled]   -C, --config-cache alias for `--cache-file=config.cache'   -n, --no-create do not create output files       --srcdir=DIR find the sources in DIR [configure dir or `..'] 
Installation directories:
  --prefix=PREFIX install architecture-independent files in PREFIX                           [/usr/local/pgsql]
  --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX                           [PREFIX]

By default, `make install' will install all the files in
`/usr/local/pgsql/bin', `/usr/local/pgsql/lib' etc.  You can specify
an installation prefix other than `/usr/local/pgsql' using `--prefix',
for instance `--prefix=$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR user executables [EPREFIX/bin]   --sbindir=DIR system admin executables [EPREFIX/sbin]   --libexecdir=DIR program executables [EPREFIX/libexec]   --sysconfdir=DIR read-only single-machine data [PREFIX/etc]   --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]   --localstatedir=DIR modifiable single-machine data [PREFIX/var]   --libdir=DIR object code libraries [EPREFIX/lib]   --includedir=DIR C header files [PREFIX/include]   --oldincludedir=DIR C header files for non-gcc [/usr/include]   --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]   --datadir=DIR read-only architecture-independent data [DATAROOTDIR]   --infodir=DIR info documentation [DATAROOTDIR/info]   --localedir=DIR locale-dependent data [DATAROOTDIR/locale]   --mandir=DIR man documentation [DATAROOTDIR/man]   --docdir=DIR documentation root [DATAROOTDIR/doc/postgresql]   --htmldir=DIR html documentation [DOCDIR]   --dvidir=DIR dvi documentation [DOCDIR]   --pdfdir=DIR pdf documentation [DOCDIR]   --psdir=DIR ps documentation [DOCDIR] 
System types:
  --build=BUILD configure for building on BUILD [guessed]   --host=HOST cross-compile to build programs to run on HOST [BUILD] 
Optional Features:
  --disable-option-checking ignore unrecognized --enable/--with options   --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)   --enable-FEATURE[=ARG] include FEATURE [ARG=yes]   --disable-integer-datetimes                           disable 64-bit integer date/time support
  --enable-nls[=LANGUAGES]                           enable Native Language Support
  --disable-rpath do not embed shared library search path in                           executables
  --disable-spinlocks do not use spinlocks   --disable-atomics do not use atomic operations   --enable-debug build with debugging symbols (-g)   --enable-profiling build with profiling enabled   --enable-coverage build with coverage testing instrumentation   --enable-dtrace build with DTrace support   --enable-tap-tests enable TAP tests (requires Perl and IPC::Run)   --enable-depend turn on automatic dependency tracking   --enable-cassert enable assertion checks (for debugging)   --disable-thread-safety disable thread-safety in client libraries   --disable-largefile omit support for large files   --disable-float4-byval disable float4 passed by value   --disable-float8-byval disable float8 passed by value 
Optional Packages:
  --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]   --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)   --with-extra-version=STRING                           append STRING to version
  --with-template=NAME override operating system template   --with-includes=DIRS look for additional header files in DIRS   --with-libraries=DIRS look for additional libraries in DIRS   --with-libs=DIRS alternative spelling of --with-libraries   --with-pgport=PORTNUM set default port number [5432]   --with-blocksize=BLOCKSIZE                           set table block size in kB [8]
  --with-segsize=SEGSIZE set table segment size in GB [1]   --with-wal-blocksize=BLOCKSIZE                           set WAL block size in kB [8]
  --with-wal-segsize=SEGSIZE                           set WAL segment size in MB [16]
  --with-CC=CMD set compiler (deprecated)   --with-tcl build Tcl modules (PL/Tcl)   --with-tclconfig=DIR tclConfig.sh is in DIR   --with-perl build Perl modules (PL/Perl)   --with-python build Python modules (PL/Python)   --with-gssapi build with GSSAPI support   --with-krb-srvnam=NAME default service principal name in Kerberos (GSSAPI)                           [postgres]
  --with-pam build with PAM support   --with-bsd-auth build with BSD Authentication support   --with-ldap build with LDAP support   --with-bonjour build with Bonjour support   --with-openssl build with OpenSSL support   --with-selinux build with SELinux support   --with-systemd build with systemd support   --without-readline do not use GNU Readline nor BSD Libedit for editing   --with-libedit-preferred                           prefer BSD Libedit over GNU Readline
  --with-uuid=LIB build contrib/uuid-ossp using LIB (bsd,e2fs,ossp)   --with-ossp-uuid obsolete spelling of --with-uuid=ossp   --with-libxml build with XML support   --with-libxslt use XSLT support when building contrib/xml2   --with-system-tzdata=DIR                           use system time zone data in DIR
  --without-zlib do not use Zlib   --with-gnu-ld assume the C compiler uses GNU ld [default=no] 
Some influential environment variables:
  CC          C compiler command
  CFLAGS      C compiler flags
  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
              nonstandard directory <lib dir>
  LIBS        libraries to pass to the linker, e.g. -l<library>
  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
              you have headers in a nonstandard directory <include dir>
  CPP         C preprocessor
  LDFLAGS_EX  extra linker flags for linking executables only
  LDFLAGS_SL  extra linker flags for linking shared libraries only
  DOCBOOKSTYLE
              location of DocBook stylesheets

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

在一次postgresql 大會上，平安科技的汪洋大神分享了他們在實際中添加的一個必要的參數，你們參考下。

--with-segsize
單個文件大小，建議10G以上，避免文件數太多
--with-wal-segsize
單個WAL文件大小，默認時 16MB
--with-libedit-preferred
--with-python
--with-uuid

就是 configure 時，添加以下參數：

--with-libedit-preferred --with-python --with-uuid=ossp --with-segsize=10 --with-blocksize=16 --with-wal-segsize=64 --with-wal-blocksize=16

下面是本地的操做

# cd /tmp/pgsoftware/postgresql-9.6.3

# ./configure --prefix=/usr/pgsql-9.6 --with-perl --with-tcl --with-python --with-openssl --with-pam --without-ldap --with-libxml --with-libxslt --enable-thread-safety --enable-dtrace --enable-debug --with-libedit-preferred --with-uuid=ossp --with-segsize=10 --with-blocksize=16 --with-wal-segsize=64 --with-wal-blocksize=16 

# make world
# make install-world

# su - postgres
$ cd /usr/pgsql-9.6
$ ls -l
total 16
drwxrwxr-x 2 root root 4096 May 22 17:59 bin
drwxrwxr-x 6 root root 4096 May 22 17:59 include
drwxrwxr-x 4 root root 4096 May 22 17:59 lib
drwxrwxr-x 6 root root 4096 May 22 17:59 share

一旦軟件構建完成並安裝好，你能夠經過pg_config命令得到一份PostgreSQL系統的配置：

$ pg_config --bindir 
$ pg_config --includedir
$ pg_config --libdir
$ pg_config --configure
$ pg_config --version

運行 initdb 工具，建立數據庫

$ /usr/pgsql-9.6/bin/initdb -D /var/lib/pgsql/9.6/data


~~~~~~腳本最後輸出以下
WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.


Success. You can now start the database server using:


    /usr/pgsql-9.6/bin/pg_ctl -D /var/lib/pgsql/9.6/data -l logfile start


啓動 postgresql 服務
/usr/pgsql-9.6/bin/pg_ctl -D /var/lib/pgsql/9.6/data  start

嘗試下是否工做
/usr/pgsql-9.6/bin/createdb test
/usr/pgsql-9.6/bin/psql test
