openresty 安装

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。
安装

安装OpenResty

 安装依赖包
 $ yum install -y readline-devel pcre-devel openssl-devel gcc

 下载最新OpenResty源码包
 $ cd /usr/local/src/ $ wget https://openresty.org/download/openresty-1.15.8.2.tar.gz

 编译安装：
 $ tar zxvf openresty-1.15.8.2.tar.gz $ cd openresty-1.15.8.2/ $ ./configure --prefix=/usr/local/openresty --with-luajit --with-http_stub_status_module --with-pcre --with-pcre-jit $ gmake && gmake install
 补充： 关于gmake和make的区别

配置waf规则

下载waf规则lua文件：waf

$ cd /usr/local/src
$ git clone https://github.com/unixhot/waf.git
$ cp -a /usr/local/src/waf/waf /usr/local/openresty/nginx/conf

 配置OpenResty：vim /usr/local/openresty/nginx/conf/nginx.conf
 http {     include       mime.types;     default_type  application/octet-stream;     lua_shared_dict limit 50m;     lua_package_path "/usr/local/openresty/nginx/conf/waf/?.lua";     init_by_lua_file "/usr/local/openresty/nginx/conf/waf/init.lua";     access_by_lua_file "/usr/local/openresty/nginx/conf/waf/access.lua";

 配置拦截后返回信息：vim /usr/local/openresty/nginx/conf/waf/config.lua
 --if config_waf_output ,setting url config_waf_redirect_url = "https://www.baidu.com" -- 重定向返回的url config_output_html=[[ ... ]]

 启动OpenResty：
 $ /usr/local/openresty/nginx/sbin/nginx -t $ /usr/local/openresty/nginx/sbin/nginx

 启动报错：
 nginx: [error] lua_load_resty_core failed to load the resty.core module from https://github.com/openresty/lua-resty-core; ensure you are using an OpenResty release from https://openresty.org/en/download.html (rc: 2, reason: module 'resty.core' not found:     no field package.preload['resty.core']  no file '/usr/local/openresty/nginx/conf/waf/resty/core.lua'    no file '/usr/local/openresty/site/lualib/resty/core.so'    no file '/usr/local/openresty/lualib/resty/core.so'     no file './resty/core.so'   no file '/usr/local/lib/lua/5.1/resty/core.so'  no file '/usr/local/openresty/luajit/lib/lua/5.1/resty/core.so'     no file '/usr/local/lib/lua/5.1/loadall.so'     no file '/usr/local/openresty/site/lualib/resty.so'     no file '/usr/local/openresty/lualib/resty.so'  no file './resty.so'    no file '/usr/local/lib/lua/5.1/resty.so'   no file '/usr/local/openresty/luajit/lib/lua/5.1/resty.so'  no file '/usr/local/lib/lua/5.1/loadall.so')

 解决上述报错：错误原因是找不到lualib库和resty模块，默认到/usr/local/lib/ 去找lualib，然而在编译安装OpenResty时lualib库默认放到/usr/local/openresty/lualib
 $ ln -s /usr/local/openresty/lualib /usr/local/lib/lua $ ln -s /usr/local/openresty/lualib/resty /usr/local/openresty/nginx/conf/waf/resty

 启动成功：
 $ /usr/local/openresty/nginx/sbin/nginx $ netstat -lntp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name      tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      20273/nginx: master
