其实有点类似WampServer一站式安装包

wget http://openresty.org/download/ngx_openresty-1.7.10.1.tar.gztar -zxvf ngx_openresty-1.7.10.1.tar.gzcd ngx_openresty-1.7.10.1./configuremake && make install

configure之前需要安装的相关组件

yum -y install pcre-develyum -y install gcc zlib zlib-devel openssl openssl-devel

安装目录默认会在

cd /usr/local/openresty/

测试lua环境是否正常

luaprint("hello")

测试nginx+lua

cd /usr/local/openresty/nginx/conf

在nginx.conf里添加测试内容

location /hello { default_type 'text/plain'; content_by_lua 'ngx.say("ok")'; }

location /say {
default_type text/html;
content_by_lua '
ngx.say("hello, world")
ngx.say(tostring(ngx.var.remote_addr)," ")
ngx.say(tostring(ngx.var.arg_name)," ")
';
}

启动nginx

sbin/nginx

测试：

[root@k2 nginx]# curl 'http://localhost/hello'ok

浏览器访问：

测试3:

location ~ /lua_request/(\d+)/(\d+) { #设置nginx变量 ; set $b $host; default_type "text/html"; #nginx内容处理 content_by_lua_file /test/test_request.lua; #内容体处理完成后调用 echo_after_body "ngx.var.b $b"; }

test_request.lua

脚本测试

wget --post-data 'a=1&b=2' 'http://127.0.0.1/lua_request/1/2?a=3&b=4' -O -
