Nginx插件之openresty反向代理和日志滚动配置案例

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 ;
events {
worker_connections ;
}
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 ;
upstream servers{
server s101: weight=;
server s102: weight=;
}
map $http_x_forwarded_for $clientRealIp {
~^(?P<firstAddr>[-\.]+),?.*$ $firstAddr;
}
server {
listen ;
server_name localhost;
underscores_in_headers on;
location / {
error_page = $;
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 $proxy_add_x_forwarded_for;
}
error_page /50x.html;
location = /50x.html {
root html;
}
}
}
4>.启动openresty
三.Linux环境安装openresty
为了配置起来方便，我推荐大家使用root权限，因为使用普通用户做啥都不方便，各种需要提权操作（sudo）。如果实际生产环境中你没法拿到root权限的话，那就还是乖乖用普通用户执行吧，配置起来也都大同小异。
1>.在s101上使用root用户手动添加yum源并修改yum的配置文件
[yinzhengjie@s101 ~]$ 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=
repo_gpgcheck=
gpgkey=https://openresty.org/package/pubkey.gpg
enabled=
enabled_metadata=
[root@s101 yinzhengjie]#
[root@s101 yinzhengjie]# grep keepcache /etc/yum.conf
keepcache=
[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=
[root@s101 yinzhengjie]#
2>.在s101上通过yum搜索openresty安装包
[root@s101 yinzhengjie]# yum -y search cache openresty
