nginx 增長 lua模塊

Nginx中的stub_status模塊主要用於查看Nginx的一些狀態信息. html

本模塊默認是不會編譯進Nginx的,若是你要使用該模塊,則要在編譯安裝Nginx時指定:linux

./configure –with-http_stub_status_module 這個模塊若是須要也能夠加入nginx

######################### 下面是 lua模塊git

unknown directive "access_by_lua"

unknown directive "set_unescape_uri"github

之因此報錯是缺乏nginx的三方插件，下面介紹安裝nginx的第三方插件，插件不少直介紹三個web

方式一：算法

下載 ngx_openresty，該集成包中有：Nginx，Lua或Luajit，ngx_lua，以及一些有用的Nginx第三方模塊。centos

安裝步驟：緩存

./configure --with-luajit
make
make install

安裝完成，我的建議第一種安裝方便簡單，另外這個版本還提供了不少的組件，安裝不會出現錯誤。服務器

方式二：

Ngx_lua手動編譯進Nginx。
首先，個人 Nginx 安裝路徑爲：/usr/local/nginx。

我將嘗試編譯的兩個模塊：echo，lua。
所須要的模塊以下：
    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

安裝步驟：

一、Luajit2.0.2（推薦）

Java代碼

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

安裝lua

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

若是遇到

lua.c:67:31: fatal error: readline/readline.h: No such file or directory
說明缺乏libreadline-dev依賴包

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

下面須要配置一下 luajit 或 lua 的環境變量(Nginx編譯時須要)：

Java代碼

-- 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

個人測試環境裏，配置以下：

Java代碼

export LUAJIT_LIB=/usr/local/luajit/lib
export LUAJIT_INC=/usr/local/luajit/include/luajit-2.0

二、安裝 ngx_devel_kit (NDK) 模塊

Java代碼

cd /usr/local
git clone https://github.com/simpl/ngx_devel_kit.git

下載完成後，將在 /usr/local/ 目錄下生成子目錄 ngx_devel_kit。

三、安裝 lua-nginx-module 模塊

Java代碼

cd /usr/local
git clone https://github.com/chaoslawful/lua-nginx-module.git

下載完成後，將在 /usr/local/ 目錄下生成子目錄 lua-nginx-module。

四、從新編譯Nginx，須要注意編譯順序！

Java代碼

./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

註釋：從新編譯 Nginx 二進制，Nginx 須要 quit 再啓動。而普通配置更新則 reload 便可：

    kill -HUP `cat /path/nginx/logs/nginx.pid`
    /usr/local/nginx/sbin/nginx -s reload

模塊編譯成功！

重啓Nginx服務器！

在編譯安裝 Nginx 的第三方模塊時，碰到一個錯誤：
    /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，後來Google之，發現瞭解決辦法。

在 Nginx 編譯時，須要指定 RPATH，加入下面選項便可：
    ./configure --with-ld-opt="-Wl,-rpath,$LUAJIT_LIB"
    或者
    export LD_LIBRARY_PATH=/usr/local/lib/:$LD_LIBRARY_PATH
五、測試Lua
在Nginx.conf 配置文件中，加入如下代碼：

    location /echo {
        default_type 'text/plain';
        echo 'hello echo';
    }
    location /lua {
        default_type 'text/plain';
        content_by_lua 'ngx.say("hello, lua")';
    }

重啓Nginx服務器：
    /usr/local/nginx/sbin/nginx -s reload
使用curl測試：
    [root@localhost] curl http://localhost/echo
    hello echo
    [root@localhost] curl http://localhost/lua
    hello lua

測試結果代表，兩個模塊都安裝成功！
