安装步骤:
1、Luajit2.0(推荐)或者 Lua5.1(Lua5.2暂不支持)
- wget http://luajit.org/download/LuaJIT-2.0.0-beta9.tar.gz
- tar zxvf LuaJIT-2.0.0-beta9.tar.gz
- cd LuaJIT-2.0.0-beta9
- make
- sudo make install PREFIX=/usr/local/luajit
Note: to avoid overwriting a previous version,
the beta test releases only install the LuaJIT executable under the versioned name (i.e. luajit-2.0.0-beta10).
You probably want to create a symlink for convenience, with a command like this:
sudo ln -sf luajit-2.0.0-beta9 /usr/local/bin/luajit (加上这句命令)
下面需要配置一下 luajit 或 lua 的环境变量(Nginx编译时需要):
- -- luajit --
- # tell nginx's build system where to find LuaJIT:
- export LUAJIT_LIB=/path/to/luajit/lib
- export LUAJIT_INC=/path/to/luajit/include/luajit-2.0
-
- -- lua --
- # or tell where to find Lua if using Lua instead:
- export LUA_LIB=/path/to/lua/lib
- export LUA_INC=/path/to/lua/include
我的测试环境里,配置如下:
- export LUAJIT_LIB=/usr/local/luajit/lib
- export LUAJIT_INC=/usr/local/luajit/include/luajit-2.0
2、安装 ngx_devel_kit (NDK) 模块
- cd /usr/local
- git clone https://github.com/simpl/ngx_devel_kit.git
下载完成后,将在 /usr/local/ 目录下生成子目录 ngx_devel_kit。
3、安装 lua-nginx-module 模块
- cd /usr/local
- git clone https://github.com/chaoslawful/lua-nginx-module.git
下载完成后,将在 /usr/local/ 目录下生成子目录 lua-nginx-module。
4、重新编译Nginx,需要注意编译顺序!
- ./configure --prefix=/usr/local/nginx \
- --with-ld-opt="-Wl,-rpath,$LUAJIT_LIB" \
- --add-module=/usr/local/ngx_devel_kit \
- --add-module=/usr/local/echo-nginx-module \
- --add-module=/usr/local/lua-nginx-module
- make -j2
- make install
注释:
重新编译
Nginx
二进制,
Nginx
需要
quit
再启动。而普通配置更新则
reload
即可:
- kill -HUP `cat /path/nginx/logs/nginx.pid`
- /usr/local/nginx/sbin/nginx -s reload
模块编译成功!
重启Nginx服务器!
我在编译安装 Nginx 的第三方模块时,碰到一个错误:
- /usr/local/nginx/sbin/ngxin -s reload
- /usr/local/nginx/sbin/nginx: error while loading shared libraries: libluajit-5.1.so.2: cannot open shared object file: No such file or directory
百事不得其解,后来Google之,发现了解决办法。
在 Nginx 编译时,需要指定 RPATH,加入下面选项即可:
- ./configure --with-ld-opt="-Wl,-rpath,$LUAJIT_LIB"
-
- 或者
-
- export LD_LIBRARY_PATH=/usr/local/lib/:$LD_LIBRARY_PATH
5、测试Lua
在Nginx.conf 配置文件中,加入以下代码:
- location /echo {
- default_type 'text/plain';
- echo 'hello echo';
- }
-
- location /lua {
- default_type 'text/plain';
- content_by_lua 'ngx.say("hello, lua")';
- }
重启Nginx服务器:
- /usr/local/nginx/sbin/nginx -s reload
使用curl测试:
- [root@localhost] curl http://localhost/echo
- hello echo
- [root@localhost] curl http://localhost/lua
- hello lua
测试结果表明,两个模块都安装成功!
如果是要在 nginx.conf 文件中引用第三方的库,则需要在 http 段中添加下面的代码
lua_package_path '/usr/local/share/lua/5.1/?.lua;/home/resty/?.lua;';
lua_package_cpath '/usr/local/lib/lua/5.1/?.so;';
