Then, launch the nodes and connect to the coordinator: gtm -D #{var}/postgres-xc/gtm -l #{var}/postgres-xc/gtm/server.log & postgres -i -X -D #{var}/postgres-xc/datanode1 -r #{var}/postgres-xc/datanode1/server.log & postgres -i -X -D #{var}/postgres-xc/datanode2 -r #{var}/postgres-xc/datanode2/server.log & postgres -i -C -D #{var}/postgres-xc/coord -r #{var}/postgres-xc/coord/server.log & psql postgres create node datanode1 with (type='datanode', port=15432); create node datanode2 with (type='datanode', port=15433); select * from pgxc_node; select pgxc_pool_reload(); To shutdown everything, kill the processes in reverse order: kill -SIGTERM `head -1 #{var}/postgres-xc/coord/postmaster.pid` kill -SIGTERM `head -1 #{var}/postgres-xc/datanode1/postmaster.pid` kill -SIGTERM `head -1 #{var}/postgres-xc/datanode2/postmaster.pid` kill -SIGTERM `head -1 #{var}/postgres-xc/gtm/gtm.pid` If you get the following error: FATAL: could not create shared memory segment: Cannot allocate memory then you need to tweak your system's shared memory parameters: https://www.postgresql.org/docs/current/static/kernel-resources.html#SYSVIPC EOS end plist_options :startup => true # Override Formula#plist_name def plist_name(extra = nil) extra ? super()+"-"+extra : super()+"-gtm" end # Override Formula#plist_path def plist_path(extra = nil) extra ? super().dirname+(plist_name(extra)+".plist") : super() end def gtm_startup_plist(name); <<-EOPLIST.undent KeepAlive Label #{plist_name(name)} ProgramArguments #{opt_bin}/gtm -D #{var}/postgres-xc/#{name} -l #{var}/postgres-xc/#{name}/server.log RunAtLoad WorkingDirectory #{HOMEBREW_PREFIX} StandardErrorPath #{var}/postgres-xc/#{name}/server.log EOPLIST end def gtm_proxy_startup_plist(name); <<-EOPLIST.undent KeepAlive Label #{plist_name(name)} ProgramArguments #{opt_bin}/gtm_proxy -D #{var}/postgres-xc/#{name} -n 2 -s localhost -t 6666 -l #{var}/postgres-xc/#{name}/server.log RunAtLoad WorkingDirectory #{HOMEBREW_PREFIX} StandardErrorPath #{var}/postgres-xc/#{name}/server.log EOPLIST end def coordinator_startup_plist(name); <<-EOPLIST.undent KeepAlive Label #{plist_name(name)} ProgramArguments #{opt_bin}/postgres -i -C -D #{var}/postgres-xc/#{name} -r #{var}/postgres-xc/#{name}/server.log RunAtLoad WorkingDirectory #{HOMEBREW_PREFIX} StandardErrorPath #{var}/postgres-xc/#{name}/server.log EOPLIST end def datanode_startup_plist(name); <<-EOPLIST.undent KeepAlive Label #{plist_name(name)} ProgramArguments #{opt_bin}/postgres -i -X -D #{var}/postgres-xc/#{name} -r #{var}/postgres-xc/#{name}/server.log RunAtLoad WorkingDirectory #{HOMEBREW_PREFIX} StandardErrorPath #{var}/postgres-xc/#{name}/server.log EOPLIST end test do system "#{bin}/initdb", "--nodename=brew", testpath/"test" assert File.exist?("test") end end __END__ --- a/src/pl/plpython/Makefile 2011-09-23 08:03:52.000000000 +1000 +++ b/src/pl/plpython/Makefile 2011-10-26 21:43:40.000000000 +1100 @@ -24,8 +24,6 @@ # Darwin (OS X) has its own ideas about how to do this. ifeq ($(PORTNAME), darwin) shared_libpython = yes -override python_libspec = -framework Python -override python_additional_libs = endif # If we don't have a shared library and the platform doesn't allow it
