nginx 增加 lua模块

Nginx中的stub_status模块主要用于查看Nginx的一些状态信息. 

本模块默认是不会编译进Nginx的,如果你要使用该模块,则要在编译安装Nginx时指定:

./configure –with-http_stub_status_module   这个模块如果需要也可以加入

#########################  下面是 lua模块

unknown directive "access_by_lua" 

unknown directive "set_unescape_uri"

之所以报错是缺少nginx的三方插件，下面介绍安装nginx的第三方插件，插件很多直介绍三个

方式一：

下载 ngx_openresty，该集成包中有：Nginx，Lua或Luajit，ngx_lua，以及一些有用的Nginx第三方模块。

安装步骤：

./configure --with-luajit
make
make install

方式二：

Ngx_lua手动编译进Nginx。
首先，我的 Nginx 安装路径为：/usr/local/nginx。

我将尝试编译的两个模块：echo，lua。
所需要的模块如下：
    liujit             http://luajit.org  
    lua                http://www.lua.org  
    ngx_devel_kit      https://github.com/simpl/ngx_devel_kit  
    echo-nginx-module  https://github.com/agentzh/echo-nginx-module  
    lua-nginx-module   https://github.com/chaoslawful/lua-nginx-module  

安装步骤：

1、Luajit2.0.2（推荐）

wget http://luajit.org/download/LuaJIT-2.0.2.tar.gz
tar zxvf LuaJIT-2.0.2.tar.gz
cd LuaJIT-2.0.2
make
sudo make install

安装lua

tar-zxvf lua-5.2.0.tar.gz
cd lua-5.2.0
make linux
make install
完成安装.

如果遇到

lua.c:67:31: fatal error: readline/readline.h: No such file or directory
说明缺少libreadline-dev依赖包

centos: yum install readline-devel
debian: apt-get install libreadline-dev.

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-2.0.2
-- 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！

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！
