安装nginx_lua_module以及echo-nginx-module收集日志

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

安装完成，个人建议第一种安装方便简单，另外这个版本还提供了很多的组件，安装不会出现错误。

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）

Java代码

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)：

Java代码

-- 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：

Java代码

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

Java代码

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

Java代码

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！

Java代码

./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！
