nginx 增加 lua模組
Nginx中的stub_status模組主要用於檢視Nginx的一些狀態資訊.
本模組預設是不會編譯進Nginx的,如果你要使用該模組,則要在編譯安裝Nginx時指定:
./configure –with-http_stub_status_module 這個模組如果需要也可以加入
######################### 下面是 lua模組
unknown directive "access_by_lua"
unknown directive "set_unescape_uri"
之所以報錯是缺少nginx的三方外掛，下面介紹安裝nginx的第三方外掛，外掛很多直介紹三個
方式一：
下載 ngx_openresty，該整合包中有：Nginx，Lua或Luajit，ngx_lua，以及一些有用的Nginx第三方模組。
安裝步驟：
- ./configure --with-luajit
- make
- make install
安裝完成，個人建議第一種安裝方便簡單，另外這個版本還提供了很多的元件，安裝不會出現錯誤。
方式二：
Ngx_lua手動編譯進Nginx。
首先，我的 Nginx 安裝路徑為：/usr/local/nginx。
我將嘗試編譯的兩個模組：echo，lua。
所需要的模組如下：
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
安裝步驟：
1、Luajit2.0.2（推薦）
Java程式碼
- 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. 如果遇到 lua.c:67:31: fatal error: readline/readline.h: No such file or directory 說明缺少libreadline-dev依賴包 centos: yum install readline-devel debian: apt-get install libreadline-dev.
下面需要配置一下 luajit 或 lua 的環境變數(Nginx編譯時需要)：
- -- 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
我的測試環境裡，配置如下：
- export LUAJIT_LIB=/usr/local/luajit/lib
- export LUAJIT_INC=/usr/local/luajit/include/luajit-2.0
2、安裝 ngx_devel_kit (NDK) 模組
- 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。
3、安裝 lua-nginx-module 模組
Java程式碼
- 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。
4、重新編譯Nginx，需要注意編譯順序！
- ./configure --prefix=/usr/local/nginx \
- --with-ld-opt="-Wl,-rpath,$LUAJIT_LIB" \
- --add-module=/usr/local/ngx_devel_kit \
- --add-module=/usr/local/echo-nginx-module \
- --add-module=/usr/local/lua-nginx-module
- make -j2
- make install
註釋：重新編譯 Nginx 二進位制，Nginx 需要 quit 再啟動。而普通配置更新則 reload 即可：
kill -HUP `cat /path/nginx/logs/nginx.pid`
/usr/local/nginx/sbin/nginx -s reload
模組編譯成功！
重啟Nginx伺服器！
在編譯安裝 Nginx 的第三方模組時，碰到一個錯誤：
/usr/local/nginx/sbin/ngxin -s reload
/usr/local/nginx/sbin/nginx: error while loading shared libraries: libluajit-5.1.so.2: cannot open shared object file: No such file or directory
百事不得其解，後來Google之，發現瞭解決辦法。
在 Nginx 編譯時，需要指定 RPATH，加入下面選項即可：
./configure --with-ld-opt="-Wl,-rpath,$LUAJIT_LIB"
或者
export LD_LIBRARY_PATH=/usr/local/lib/:$LD_LIBRARY_PATH
5、測試Lua
在Nginx.conf 配置檔案中，加入以下程式碼：
location /echo {
default_type 'text/plain';
echo 'hello echo';
}
location /lua {
default_type 'text/plain';
content_by_lua 'ngx.say("hello, lua")';
}
重啟Nginx伺服器：
/usr/local/nginx/sbin/nginx -s reload
使用curl測試：
[[email protected]] curl http://localhost/echo
hello echo
[[email protected]] curl http://localhost/lua
hello lua
測試結果表明，兩個模組都安裝成功！
