查看原本安裝的 nginx 的編譯參數

$sudo nginx -V

下載 Nginx 原始碼(注意版本)

$ cd /opt/
$ wget http://nginx.org/download/nginx-1.14.2.tar.gz
$ tar -zxvf nginx-1.14.2.tar.gz

安裝 lua-nginx-module

安裝 LuaJIT

$ wget http://luajit.org/download/LuaJIT-2.0.5.tar.gz
$ tar -zxvf  LuaJIT-2.0.5.tar.gz
$ cd LuaJIT-2.0.5
$ make install PREFIX=/usr/local/LuaJIT

設置 PATH: /etc/profile 文件結尾加上以下內容：

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

安裝 nginx_devel_kit (下載解壓不需安裝)

$ cd /opt/
$ wget https://github.com/simplresty/ngx_devel_kit/archive/v0.3.0.tar.gz
$ tar zxvf v0.3.0.tar.gz

$ ls | grep ngx_devel_kit
ngx_devel_kit-0.3.0

編譯 Nginx

安裝 pcre 相依程式庫

$ yum install readline-devel pcre-devel openssl-devel 

注意：重新编译 Nginx 二进制，Nginx 需要停止重启。而普通配置更新则 reload 即可：(因本文是用動態模組方式安裝，只須重載即可，不需停止)

$ sudo systemctl stop nginx
或者
$ sudo nginx -s stop

添加以下編譯參數於第一步取得編譯參數結尾

--with-ld-opt=-Wl,-rpath,/usr/local/LuaJIT/lib --add-dynamic-module=/opt/ngx_devel_kit-0.3.0 --add-dynamic-module=/opt/lua-nginx-module-0.10.13

成為以下 ./configure 的參數，並進行編譯與安裝

$ cd /opt/nginx-1.12.2/
$ ./configure --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx --with-compat --with-file-aio --with-threads --with-http_addition_module --with-http_auth_request_module --with-http_dav_module --with-http_flv_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_mp4_module --with-http_random_index_module --with-http_realip_module --with-http_secure_link_module --with-http_slice_module --with-http_ssl_module --with-http_stub_status_module --with-http_sub_module --with-http_v2_module --with-mail --with-mail_ssl_module --with-stream --with-stream_realip_module --with-stream_ssl_module --with-stream_ssl_preread_module --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -fPIC' --with-ld-opt='-Wl,-z,relro -Wl,-z,now -pie' --with-ld-opt=-Wl,-rpath,/usr/local/LuaJIT/lib --add-dynamic-module=/opt/ngx_devel_kit-0.3.0 --add-dynamic-module=/opt/lua-nginx-module-0.10.13

$ make -j2
$ make install

编译成功后，会把模块安装在nginx/modules/目录。查看：

$ ls /etc/nginx/modules/
ndk_http_module.so  ngx_http_lua_module.so

接下来我们需要在nginx.conf配置中加入以下两行，实现动态调用模块：

load_module /etc/nginx/modules/ndk_http_module.so; 
load_module /etc/nginx/modules/ngx_http_lua_module.so;

載入模組區段:

worker_processes  1;

load_module xxx;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

events {
    worker_connections  1024;
}

http {

}

重載 Nginx

$ sudo nginx -s reload
