LUA是近几年被大家所熟习的一门轻量级语言，它的语言简练，解决效率很高。

Nginx又是一个这些年很火的web代理商和中间件服务。

Nginx+LUA被用在很多的应用场景中，就向牛郎遇到织女。

如：

1、Nginx+LUA实现7层防空规则。

2、实现代码的灰度发布

3、实现简单的json接口和数据库交互

等等

那么“幕客”今天先给大家详情少量基础的内容，就是Nginx＋LUA的安装

一、安装LUA环境及相关库

官方网站:https://github.com/openresty/lua-nginx-module

1、LuaJIT

下载LUA库

wget http://luajit.org/download/LuaJIT-2.0.2.tar.gz

make install PREFIX=/usr/local/LuaJIT

export LUAJIT_LIB=/usr/local/LuaJIT/lib

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

3、ngx_devel_kit和lua-nginx-module

下载支持LUA的nginx 板块

cd /opt/download

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

wget https://github.com/openresty/lua-nginx-module/archive/v0.10.9rc7.tar.gz

分别解压

4、编译安装

重点是在原来编译参数的基础上，加入如下：

–add-module=/opt/download/ngx_devel_kit-0.3.0 –add-module=/opt/download/lua-nginx-module-0.10.9rc7

编译如下：

./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' –add-module=/opt/download/ngx_devel_kit-0.3.0 –add-module=/opt/download/lua-nginx-module-0.10.9rc7

make -j 4 && make install

二、测试

1、通过nginx -V命令测试能否编译

如下：

# nginx -V
nginx version: nginx/1.12.2
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-18) (GCC)
built with OpenSSL 1.0.1e-fips 11 Feb 2013
TLS SNI support enabled
configure arguments: --user=nginx --group=nginx --with-http_ssl_module --with-http_sub_module --with-http_stub_status_module --with-http_gzip_static_module --with-pcre --with-stream --with-stream_ssl_module --with-http_gunzip_module --with-stream_realip_module --with-http_realip_module --add-module=/root/ngx_devel_kit-0.3.0 --add-module=/root/lua-nginx-module-0.10.9rc7

2、配置测试

配置nginx.conf下server一级下的 lua

server {

location /echo_imoocc {

default_type 'text/html';

content_by_lua 'ngx.say(“Hello,imoocc”)';

}

}

打开浏览器，访问地址：

出现如上页面，说明编译成功了！
