下载mysql_fdw项目文件:https://pgxn.org/dist/mysql_fdw/
注：我使用的是ubuntu18.04，可以直接在仓库查看是否有二级制安装文件，当然是有的啦，这是很方便的一个方法
$ sudo apt search fdw

postgresql-10-mysql-fdw/bionic 2.3.0-2 amd64
Postgres 10 Foreign Data Wrapper for MySQL
所以直接安装完事
$ sudo apt install postgresql-10-mysql-fdw
1.好了还是进入正题，首先进入项目目录
$ cd mysql_fdw/
2.源码目录下直接提供的Makefile文件，按理说直接make就可以进行编译，哈哈哈哈，不会那么简单的，编译依赖会让你对它烦的抓脚，所以看看READ.md吧.
其中说的很清楚:一 需要postgresql相关的依赖由pg_config提供； 二 需要mysql相关的依赖由mysql_config提供
This PostgreSQL extension implements a Foreign Data Wrapper (FDW) for [MySQL][1]. Please note that this version of mysql_fdw works with PostgreSQL and EDB Postgres Advanced Server 9.5, 9.6, 10, 11, 12, and 13. 1. Installation --------------- To compile the [MySQL][1] foreign data wrapper, MySQL‘s C client library is needed. This library can be downloaded from the official [MySQL website][1]. 1. To build on POSIX-compliant systems you need to ensure the `pg_config` executable is in your path when you run `make`. This executable is typically in your PostgreSQL installation‘s `bin` directory. For example: ``` $ export PATH=/usr/local/pgsql/bin/:$PATH ``` 2. The `mysql_config` must also be in the path, it resides in the MySQL `bin` directory. ``` $ export PATH=/usr/local/mysql/bin/:$PATH ``` 3. Compile the code using make. ``` $ make USE_PGXS=1 ``` 4. Finally install the foreign data wrapper. ``` $ make USE_PGXS=1 install ``` Not that we have tested the `mysql_fdw` extension only on MacOS and Ubuntu systems, but other \*NIX‘s should also work.
3.接下来开始编译
make USE_PGXS=1
会出现下面的报错
make: mysql_config: Command not found Makefile:58: ../../src/Makefile.global: No such file or directory Makefile:59: /contrib/contrib-global.mk: No such file or directory
解决:make: mysql_config: Command not found ,安装 libmysqlclient-dev
sudo apt install libmysqlclient-dev
解决
Makefile:58: ../../src/Makefile.global: No such file or directory
Makefile:59: /contrib/contrib-global.mk: No such file or directory 安装 postgresql-server-dev-all,postgresql-common
sudo apt-get install postgresql-server-dev-all sudo apt-get install postgresql-common
4.然后便可以愉快的编译了
make USE_PGXS=1
5.安装
make USE_PGXS=1 install
