nginx 添加lua

• 默认情况下Nginx不支持Lua模块，需要安装LuaJIT解释器，并且重新编译Nginx，或者可使用国人开发的openrestry

• 需要的模块：LuaJIT,Ngx_devel和lua-nginx-module
• Luajit官网：https://luajit.org

1. 环境准备

   yum install -y gcc gcc-c++ make pcre-devel zlib-devel openssl-devel环境准备

2. 安装LuaJIT


   wget https://luajit.org/download/LuaJIT-2.0.5.tar.gz

3. 下载、解压lua模块

   wget https://github.com/simpl/ngx_devel_kit/archive/v0.3.0.tar.gz
   wget https://github.com/openresty/lua-nginx-module/archive/v0.10.21rc2.tar.gz

4. 保留原始模块，用大写V查看已经安装的模块

   nginx -V

   nginx version: nginx/1.23.1
   built by gcc 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC) 
   built with OpenSSL 1.0.2k-fips  26 Jan 2017
   TLS SNI support enabled
   configure arguments: --with-http_stub_status_module --with-http_ssl_module

5. 路径切换到nginx安装包，这里是安装包路径不是安装路径，重新加载配置

   ./configure --prefix=/安装路径/nginx --with-http_ssl_module --with-http_flv_module --with-http_stub_status_module --with-http_gzip_static_module --with-http_realip_module --with-pcre --add-module=/模块解压位置/lua-nginx-module-0.10.21rc2 --add-module=/模块解压位置/ngx_devel_kit-0.3.0

    

6. 执行make，千万不要  install

7. 我的错误，这个错误是配置文件错误，手动修改文件
   

   error: ‘ngx_http_headers_in_t’ has no member named ‘cookies’

   根据路径指引，找到 cookies修改
   cookies   →   cookie

8. 重复  步骤 6

9. 备份

   cp /安装目录/sbin/nginx  nginx.xxx.bak

10. 配置覆盖

    cp  /安装包目录/objs/nginx  /安装目录/sbin/nginx

11. 试试

    nginx -V

12. 重启

    nginx -s reload

13. 可能出现的其他错误

    [root@localhost /]# nginx 
    nginx: [alert] detected a LuaJIT version which is not OpenResty's; many optimizations will be disabled and performance will be compromised (see https://github.com/openresty/luajit2 for OpenResty's LuaJIT or, even better, consider using the OpenResty releases from https://openresty.org/en/download.html)
    nginx: [alert] failed to load the 'resty.core' module (https://github.com/openresty/lua-resty-core); ensure you are using an OpenResty release from https://openresty.org/en/download.html (reason: module 'resty.core' not found:
        no field package.preload['resty.core']
        no file './resty/core.lua'
        no file '/usr/local/share/luajit-2.0.5/resty/core.lua'
        no file '/usr/local/share/lua/5.1/resty/core.lua'
        no file '/usr/local/share/lua/5.1/resty/core/init.lua'

        no file '/usr/local/lib/lua/5.1/loadall.so') in /usr/local/nginx/conf/nginx.conf:31

     

    原因是缺少 openresty 或者版本过低

    安装或升级最新版本：https://openresty.org/en/download.html

    cd /usr/local/lib
    rm -rf ./resty
    ln -s /usr/local/openresty/lualib/resty /usr/local/lib
    nginx  或者/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
