nginx安装lua模块实现高并发

nginx安装lua扩展模块

1.下载安装LuaJIT-2.0.4.tar.gz

    wget -c http://luajit.org/download/LuaJIT-2.0.4.tar.gz

    tar xzvf LuaJIT-2.0.4.tar.gz

    cd LuaJIT-2.0.4

   make install PREFIX=/usr/local/luajit

    #注意环境变量!

    export LUAJIT_LIB=/usr/local/luajit/lib

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

2.下载解压ngx_devel_kit

    wget https://github.com/simpl/ngx_devel_kit/archive/v0.3.0.tar.gz

    tar -xzvf v0.3.0.tar.gz

3.下载解压lua-nginx-module

    wget https://github.com/openresty/lua-nginx-module/archive/v0.10.8.tar.gz

    tar -xzvf v0.10.8.tar.gz

4.下载安装nginx-1.10.3.tar.gz

     wget http://nginx.org/download/nginx-1.10.3.tar.gz

     tar -xzvf nginx-1.10.3.tar.gz

    cd nginx-1.10.3

   ./configure --add-module=/opt/soft/ngx_devel_kit-0.3.0 --add-module=/opt/soft/lua-nginx-module-0.10.8

   #注意ngx_devel_kit和lua-nginx-module以实际解压路径为准

   make -j2

   make install

注：报错gcc需要安装，可以执行

yum install -y gcc g++ gcc-c++

依赖报错，可以执行

yum -y install zlib zlib-devel openssl openssl--devel pcre pcre-devel

5.验证

    #将nginx做成命令

    ln -s /usr/local/nginx/sbin/nginx /usr/bin/nginx

   cd /usr/local/nginx/conf/

   vi nginx.conf

     #lua指令方式

    #在server 中添加一个localtion

    location /hello {

            default_type 'text/plain';

            content_by_lua 'ngx.say("hello, lua")';

        }

    #lua文件方式

   #在server 中添加一个localtion

    location /lua {

       default_type 'text/html';

       content_by_lua_file conf/lua/test.lua; #相对于nginx安装目录

    }

   #test.lua文件内容

     ngx.say("hello world");

   #启动nginx（已经做了软连接了，可以在任何目录启动）

  nginx

  注：

      报错nginx: error while loading shared libraries: libluajit-5.1.so.2: cannot open shared object file: No such file or directory 可以执行

       ln -s /usr/local/luajit/lib/libluajit-5.1.so.2 /lib64/libluajit-5.1.so.2

       具体source的路径已实际安装路径为准

window平台开发代码部署到Linux服务器

   由于两个平台的不同导致脚本文件的编码类型不一致  部署后会出现一些诡异的问题
