在LNMP安裝包後，重編譯nginx，並添加ngx_lua模塊
1」Download
wget http://luajit.org/download/LuaJIT-2.0.2.tar.gz
wget https://github.com/simpl/ngx_devel_kit/archive/v0.2.19.tar.gz
wget https://github.com/chaoslawful/lua-nginx-module/archive/v0.9.1.tar.gz
nginx最新穩定版是1.4.3,get下來
wget http://nginx.org/download/nginx-1.4.3.tar.gz
2」安裝LuaJIT
tar -zxvf LuaJIT-2.0.2.tar.gz
cd LuaJIT-2.0.2
make
make install
export LUAJIT_LIB=/usr/local/lib
export LUAJIT_INC=/usr/local/include/luajit-2.0
3」copy模塊
解壓下載下來的ngx_devel_kit以及lua-nginx-module到/usr/local/src目錄下，即
/usr/local/src/lua-nginx-module-0.9.1/
/usr/local/src/ngx_devel_kit-0.2.19/
3」重新編譯Nginx
解壓nginx包，configure一下（參考LNMP安裝包，未加其他修改）
./configure --user=www --group=www --prefix=/usr/local/nginx --with-ld-opt="-Wl,-rpath,$LUAJIT_LIB" --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-ipv6 \
--add-module=/usr/local/src/lua-nginx-module-0.9.1/ \
--add-module=/usr/local/src/ngx_devel_kit-0.2.19/
OK後make，別make install，否則就覆蓋安裝
4」備份替換
make完後在objs目錄下多了個nginx，即新版本的程序
備份舊的nginx程序
cp /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak
新nginx程序覆蓋舊的
cp objs/nginx /usr/local/nginx/sbin/nginx
測試新的nginx程序是否正確
/usr/local/nginx/sbin/nginx -t
nginx: theconfiguration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx:configuration file /usr/local/nginx/conf/nginx.conf test issuccessful
平滑重啟nginx
/usr/local/nginx/sbin/nginx -s reload
查看ngixn版本及其編譯參數
/usr/local/nginx/sbin/nginx -V
「問題解決」
1.如遇到找不到庫文件
echo “/usr/local/lib” > /etc/ld.so.conf.d/usr_local_lib.conf
ldconfig
即可
2./usr/local/nginx/sbin/nginx: error while loading shared libraries: libluajit-5.1.so.2: cannot open shared object file: No such file or directory
在 Nginx 編譯時，需要指定 RPATH，記得加入下面選項：
./configure --with-ld-opt="-Wl,-rpath,$LUAJIT_LIB"
或者export LD_LIBRARY_PATH=/usr/local/lib/:$LD_LIBRARY_PATH
