编译安装openresty - 码农教程

OpenResty 是一个基于 Nginx 与 Lua 的高性能 Web 平台，其内部集成了大量精良的 Lua 库、第三方模块以及大多数的依赖项。用于方便地搭建能够处理超高并发、扩展性极高的动态 Web 应用、Web 服务和动态网关。

OpenResty 通过汇聚各种设计精良的 Nginx 模块（主要由 OpenResty 团队自主开发），从而将 Nginx 有效地变成一个强大的通用 Web 应用平台。这样，Web 开发人员和系统工程师可以使用 Lua 脚本语言调动 Nginx 支持的各种 C 以及 Lua 模块，快速构造出足以胜任 10K 乃至 1000K 以上单机并发连接的高性能 Web 应用系统。

OpenResty 的目标是让你的Web服务直接跑在 Nginx 服务内部，充分利用 Nginx 的非阻塞 I/O 模型，不仅仅对 HTTP 客户端请求,甚至于对远程后端诸如 MySQL、PostgreSQL、Memcached 以及 Redis 等都进行一致的高性能响应。

服务器环境：
操作系统：Centos7.2
LNMP环境：军哥一键安装包

一、准备工作

因为我当前安装是在LNMP环境下安装的，所以需要将原有的nginx做一个备份操作，以确保openresty安装出错的时候能立马回退到nginx可用状态。

 [root@niaoyun /]# cd /usr/local/
 [root@niaoyun local]# mv nginx nginxold/

二、安装依赖包

Fedora 和 RedHat用户,推荐您使用yum安装以下的开发库,其他版本用户请参考官方文档.

[root@niaoyun /]# yum -y install readline-devel pcre-devel openssl-devel gcc postgresql-devel

三、编译安装openresty

3.1 下载openresty安装包

[root@niaoyun down]# wget https://openresty.org/download/openresty-1.11.2.1.tar.gz

3.2 解压openresty安装包

[root@niaoyun down]# tar -zxvf openresty-1.11.2.1.tar.gz

3.3 编译安装openresty

[root@niaoyun down]# cd openresty-1.11.2.1/
[root@niaoyun openresty-1.11.2.1]# ./configure --prefix=/usr/local --with-luajit --without-http_redis2_module --with-http_iconv_module --with-http_postgres_module --with-http_stub_status_module --with-http_ssl_module --with-http_stub_status_module
[root@niaoyun openresty-1.11.2.1]# gmake
[root@niaoyun openresty-1.11.2.1]# gmake install

四、测试openresty

4.1 curl测试http头信息，查看server类型。

[root@niaoyun openresty-1.11.2.1]# curl -I http://127.0.0.1
HTTP/1.1 200 OK
Server: openresty
Date: Sat, 29 Oct 2016 08:57:04 GMT
Content-Type: text/html
Content-Length: 2502
Last-Modified: Fri, 28 Oct 2016 18:51:49 GMT
Connection: keep-alive
Vary: Accept-Encoding
ETag: "58139e45-9c6"
Accept-Ranges: bytes

4.2 使用ab压测工具测试

[root@niaoyun openresty-1.11.2.1]# ab -c10 -n50000 http://127.0.0.1:80/
