编译安装 pgrouting

下载源码包

git clone https://github.com/pgRouting/pgrouting.git
或下载压缩包
https://github.com/pgRouting/pgrouting/releases

配置编译参数

export PATH=/usr/local/pgsql/bin:$PATH
export LD_LIBRARY_PATh=/usr/local/pgsql/lib:$LD_LIBRARY_PATh
tar xf pgrouting-3.6.0.tar.gz
cd pgrouting-3.6.0
mkdir build && cd build
cmake .. \-DCMAKE_BUILD_TYPE=Release \-DCMAKE_INSTALL_PREFIX=/usr/local/pgsql \-DPOSTGRESQL_EXECUTABLE=/usr/local/pgsql/bin/pg_config

编译安装

make -j$(nproc)
make install
ldconfig

初始化数据库

useradd -m postgres
chown -R postgres:postgres /usr/local/pgsql
su - postgres
cd /usr/local/pgsql
./bin/initdb -U postgres -E UTF8 -D ./data

建表并检查列是否使用了 lz4 压缩算法

drop table if exists test_lz4;
CREATE TABLE test_lz4 (txt text COMPRESSION lz4);
INSERT INTO test_lz4 SELECT repeat('abcd',10000);
\d+ test_lz4
select pg_column_compression(txt) from test_lz4;postgres=# select pg_column_compression(txt) from test_lz4;pg_column_compression 
-----------------------lz4
(1 row)drop table if exists test;
CREATE TABLE test (txt text);
INSERT INTO test SELECT repeat('abcd',10000);
\d+ test
select pg_column_compression(txt) from test;
postgres=# select pg_column_compression(txt) from test;pg_column_compression 
-----------------------lz4
(1 row)

检查 postgis 与 pgrouting 是否可以成功创建
