Nginx与Lua的开发

1. Lua基础语法

安装lua

hello world

也可以编写lua脚本

运行脚本

lua注释

变量

局部变量的话前面加个local

循环

if语句

2. Nginx与Lua开发环境

Nginx编译安装Lua模块

一、安装LUA环境及相关库

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

1、LuaJIT

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

2、ngx_devel_kit和lua-nginx-module

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、安装

3、重新编译编译Nginx
cd /opt/download
wget http://nginx.org/download/nginx-1.12.1.tar.gz
执行解压，后按照如下方式编译：

./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

4、加载lua库，加入到ld.so.conf文件
echo "/usr/local/LuaJIT/lib" >> /etc/ld.so.conf
然后执行如下命令：
ldconfig
