Linux下安装PHP的lua扩展库

一、安装Lua 5.3.4

下载

http://www.lua.org/ftp/lua-5.3.4.tar.gz

tar xvf lua-5.3.4.tar.gz

cd lua-5.3.4

重要：进入解压缩后的路径 cd .../lua-5.3.4/src 打开Makefile文件 在CFLAG一行 添加选项 -fPIC 像这样:

找到源文件的这行替换掉

CFLAGS= -O2 -Wall -DLUA_COMPAT_ALL $(SYSCFLAGS) -fPIC $(MYCFLAGS)

然后编译、安装

 make linux 
 sudo make install

执行完成后安装lua成功，可以查看lua 版本是否为刚安装的版本

tinywan@tinywan:~/lua-5.3.4$ lua -v
Lua 5.3.4  Copyright (C) 1994-2017 Lua.org, PUC-Rio

查看 /usr/local/include/ 路径下是否有 lua.h， 为该头文件创建一个软链

tinywan@tinywan:/usr/local/include$ ls 
lauxlib.h  libssh2.h  libssh2_publickey.h  libssh2_sftp.h  luaconf.h  lua.h  lua.hpp  lualib.h
tinywan@tinywan:/usr/local/include$ ln -s /usr/local/include/lua.h /usr/include/lua/lua.h
ln: 无法创建符号链接'/usr/include/lua/lua.h': 没有那个文件或目录
tinywan@tinywan:/usr/local/include$ ln -s /usr/local/include/lua.h /usr/include/lua/lua.h
ln: 无法创建符号链接'/usr/include/lua/lua.h': 没有那个文件或目录
tinywan@tinywan:/usr/local/include$ mkdir -P /usr/include/lua
mkdir：无效选项 -- P
Try 'mkdir --help' for more information.
tinywan@tinywan:/usr/local/include$ mkdir -R /usr/include/lua
mkdir：无效选项 -- R
Try 'mkdir --help' for more information.
tinywan@tinywan:/usr/local/include$ mkdir - /usr/include/lua
mkdir: 无法创建目录"-": 权限不够
mkdir: 无法创建目录"/usr/include/lua": 权限不够
tinywan@tinywan:/usr/local/include$ sudo mkdir - /usr/include/lua
tinywan@tinywan:/usr/local/include$ ln -s /usr/local/include/lua.h /usr/include/lua/lua.h
ln: 无法创建符号链接'/usr/include/lua/lua.h': 权限不够
tinywan@tinywan:/usr/local/include$ sudo ln -s /usr/local/include/lua.h /usr/include/lua/lua.h
tinywan@tinywan:/usr/local/include$ 

将 liblua.a 放到 /usr/lib 目录下，先查找liblua.a文件在哪个位置，一般是在/usr/local/lib/liblua.a

tinywan@tinywan:/usr/local/include$ whereis liblua.a
liblua: /usr/local/lib/liblua.a
tinywan@tinywan:/usr/local/include$ cp /usr/local/lib/liblua.a /usr/lib/liblua.a
cp: 无法创建普通文件'/usr/lib/liblua.a': 权限不够
tinywan@tinywan:/usr/local/include$ sudo cp /usr/local/lib/liblua.a /usr/lib/liblua.a
tinywan@tinywan:/usr/local/include$

如果不安装lua，在./configured的时候提示一下错误信息

configure: error: Please reinstall the lua distribution - lua.h should be in <lua-dir>/include/

二、安装phplua 扩展

wget http://pecl.php.net/get/lua-2.0.3.tgz

tar xvf lua-2.0.3.tgz

cd lua-2.0.3

phpize

./configure

编译、安装

tinywan@tinywan:~/lua-2.0.3$ make
/bin/bash /home/tinywan/lua-2.0.3/libtool --mode=compile cc ...

tinywan@tinywan:~/lua-2.0.3$ sudo make install
/bin/bash /home/tinywan/lua-2.0.3/libtool --mode=install cp ./lua.la /home/tinywan/lua-2.0.3/modules
libtool: install: cp ./.libs/lua.so /home/tinywan/lua-2.0.3/modules/lua.so
libtool: install: cp ./.libs/lua.lai /home/tinywan/lua-2.0.3/modules/lua.la
libtool: finish: PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin:/sbin" ldconfig -n /home/tinywan/lua-2.0.3/modules
----------------------------------------------------------------------
Libraries have been installed in:
   /home/tinywan/lua-2.0.3/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the 'LD_RUN_PATH' environment variable
     during linking
   - use the '-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to '/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
Installing shared extensions:     /usr/lib/php/20151012/

查看lua.so 文件

tinywan@tinywan:/usr/lib/php/20151012$ ls
build        ctype.so  exif.so      ftp.so      iconv.so  lua.so

修改PHP 配置文件

sudo vim /etc/php/7.0/cli/php.ini
#添加一下内容
extension=/usr/lib/php/20151012/lua.so

tinywan@tinywan:/usr/lib/php/20151012$ php -m | grep lua
lua

安装完毕

三、测试

文件test_lua.php

<?php
$lua = new Lua();
$lua->eval(<<<CODE
    function dummy(foo, bar)
        print(foo, ",", bar)
    end
CODE
);
$lua->call("dummy", array("Lua", "geiliable
"));
$lua->dummy("Lua", "geiliable"); // __call()
var_dump($lua->call(array("table", "concat"), array(array(1=>1, 2=>2, 3=>3), "-")));
?>

执行结果：

tinywan@tinywan:~/PHP7$ php test_lua.php 
Lua,geiliable
Lua,geiliablestring(11) "1.0-2.0-3.0"
