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

一、配置基础环境

[root@nginx_lua ~]# yum install -y gcc gcc-c++ make pcre-devel zlib-devel openssl-devel

二、下载 luajit和ngx_devel_kit以及lua-nginx-module解压

[root@nginx_lua ~]# mkdir -p /soft/src 
[root@nginx_lua ~]# cd /soft/src/
wget https://luajit.org/download/LuaJIT-2.0.4.tar.gz
wget https://github.com/simpl/ngx_devel_kit/archive/v0.2.19.tar.gz
wget https://github.com/openresty/lua-nginx-module/archive/v0.10.13.tar.gz

三、 解压ngx_devel_kit以及lua-nginx-module

[root@nginx_lua src]# tar xf v0.2.19.tar.gz
[root@nginx_lua src]# tar xf v0.10.13.tar.gz

四、 编译安装LuaJIT，即Lua及时编译器

[root@nginx_lua src]# tar xf LuaJIT-2.0.4.tar.gz
[root@nginx_lua src]# cd LuaJIT-2.0.4/
[root@nginx_lua LuaJIT-2.0.4]# make && make install

五、编译安装Nginx

[root@nginx_lua src]# wget http://nginx.org/download/nginx-1.14.2.tar.gz
[root@nginx_lua src]# tar xf nginx-1.14.2.tar.gz
[root@nginx_lua src]# cd nginx-1.14.2
[root@nginx_lua nginx-1.14.2]# ./configure --prefix=/soft/nginx --with-http_ssl_module --with-http_stub_status_module --with-http_dav_module --with-file-aio --with-http_dav_module --add-module=../ngx_devel_kit-0.2.19/ --add-module=../lua-nginx-module-0.10.13/
[root@nginx_lua nginx-1.14.2]# make && make install
[root@nginx_lua nginx-1.14.2]# ln -s /soft/nginx/sbin/nginx /usr/bin/nginx
[root@nginx_lua conf]# vim nginx.conf  #简单配置写nginx测试Nginx是否已经支持Lua(lua指令方式)
...
server {
 location /test_lua {
                default_type text/html;
                content_by_lua_block {
                        ngx.say("Hello Lua!") 
                }
        }
...
}

#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");

//建立软连接，如果不建立软链接，则会出现share object错误
[root@nginx_lua conf]# nginx -t
/soft/nginx/sbin/nginx: error while loading shared libraries: libluajit-5.1.so.2: cannot open shared object file: No such file or directory
[root@nginx_lua conf]# 

[root@nginx_lua lib64]# ln -s /usr/local/lib/libluajit-5.1.so.2 /lib64/libluajit-5.1.so.2
[root@nginx_lua lib64]# ll libluajit-5.1.so.2
lrwxrwxrwx 1 root root 33 Dec 21 20:52 libluajit-5.1.so.2 -> /usr/local/lib/libluajit-5.1.so.2
[root@nginx_lua lib64]#

#//加载lua库，加入到ld.so.conf文件（暂时不执行这一步）
#[root@nginx_lua nginx-1.14.2]# echo "/usr/local/LuaJIT/lib" >> /etc/ld.so.conf

[root@nginx_lua conf]# nginx -t
nginx: the configuration file /soft/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /soft/nginx/conf/nginx.conf test is successful
[root@nginx_lua conf]# nginx -s reload

六、测试
