2.5. Installing Pgpool-II

After extracting the source tarball, follow the steps below to build the source code and install Pgpool-II.

Since Pgpool-II 4.5, files such as configure generated by autoconf/autoreconf have been removed from the repository, so first run autoreconf -fi to generate configure.

dnf install libtool

cd pgpool-II-4.5.2
autoreconf -fi
   

Next, execute the configure script.

./configure
   

You can customize the build and installation process by supplying one or more of the following command line options to configure:

--prefix=path

Specifies the top directory where Pgpool-II binaries and related files like docs will be installed in. Default value is /usr/local.

--with-pgsql=path

Specifies the top directory where PostgreSQL's client libraries are installed. Default value is the path provided by pg_config command.

--with-openssl

Pgpool-II binaries will be built with OpenSSL support. If you plan to encrypt passwords using AES256 encryption, you need this option too. See Section 6.4 for more details. OpenSSL support is disabled by default.

--enable-sequence-lock

Use insert_lock compatible with Pgpool-II 3.0 series (until 3.0.4). Pgpool-II locks against a row in the sequence table. PostgreSQL 8.2 or later which was released after June 2011 cannot use this lock method.

--enable-table-lock

Use insert_lock compatible with Pgpool-II 2.2 and 2.3 series. Pgpool-II locks against the insert target table. This lock method is deprecated because it causes a lock conflict with VACUUM.

--with-memcached=path

Pgpool-II binaries will use memcached for in memory query cache. You have to install libmemcached.

--with-pam

Pgpool-II binaries will be built with PAM authentication support. PAM authentication support is disabled by default.

Compile the source file.

make
   

Install Pgpool-II.

make install
   

This will install Pgpool-II. (If you use Solaris or FreeBSD, replace make with gmake)
