一.openresty介绍
1>.Nginx介绍
Nginx是一款高性能web服务器和反向代理服务器，在互联网项目中使用非常频繁，尤其其出色的性能以及轻量级进程占用，已经超过了apache的httpd服务器的使用量。内部可以配置零拷贝（sendfile）实现快速文件传输。Nginx可以做反向代理，负载均衡，HTTP服务器（包含动静分离）以及正向代理。
2>.Openresty介绍
openresty是将nginx现有一些重要插件做了集成，省去安装nginx之后还需要在安装插件的繁琐步骤，内置luajit插件，能解决接受post提交请求、json消息体解析等功能。
二.Windows环境安装openresty
1>.下载openresty安装包
下载地址：http://openresty.org/cn/download.html
2>.安装openresty
安装方式很简单，解压即可。
3>.修改Windows版本的nginx.conf的配置文件内容
worker_processes 1; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; log_format main escape=json $remote_addr#$http_client_time#$time_local#$status#$request_body; access_log logs/access.log main; sendfile on; keepalive_timeout 65; upstream servers{ server s101:80 weight=1; server s102:80 weight=1; } map $http_x_forwarded_for $clientRealIp { ~^(?P<firstAddr>[0-9.]+),?.*$ $firstAddr; } server { listen 80; server_name localhost; underscores_in_headers on; location / { error_page 405 =200 $1; lua_need_request_body on; content_by_lua 'local s = ngx.var.request_body'; proxy_pass http://servers; proxy_set_header Host $host; proxy_set_header remove_user_ip $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } } }
4>.启动openresty
三.Linux环境安装openresty
为了配置起来方便，我推荐大家使用root权限，因为使用普通用户做啥都不方便，各种需要提权操作（sudo）。如果实际生产环境中你没法拿到root权限的话，那就还是乖乖用普通用户执行吧，配置起来也都大同小异。
1>.在s101上使用root用户手动添加yum源并修改yum的配置文件
[yinzhengjie@s101 ~]$ su root Password: [root@s101 yinzhengjie]# [root@s101 yinzhengjie]# vi /etc/yum.repos.d/openresty.repo [root@s101 yinzhengjie]# cat /etc/yum.repos.d/openresty.repo [openresty] name=Official OpenResty Open Source Repository for CentOS baseurl=https://openresty.org/package/centos/$releasever/$basearch skip_if_unavailable=False gpgcheck=1 repo_gpgcheck=1 gpgkey=https://openresty.org/package/pubkey.gpg enabled=1 enabled_metadata=1 [root@s101 yinzhengjie]# [root@s101 yinzhengjie]# grep keepcache /etc/yum.conf keepcache=0 [root@s101 yinzhengjie]# sed -i 's/keepcache=0/keepcache=1/' /etc/yum.conf #会将下载的文件保存 [root@s101 yinzhengjie]# [root@s101 yinzhengjie]# grep keepcache /etc/yum.conf keepcache=1 [root@s101 yinzhengjie]#
2>.在s101上通过yum搜索openresty安装包
