OpenResty--------企业级入门实践篇

前景

前篇介绍了OpenResty核心概念，优势与架构等信息，进行本篇之前建议至少观看一遍。OpenResty--------企业级理论实践篇
本篇将进行OpenResty的安装与编写第一个应用过程。
注：本篇采用CentOS 7(7.4)系统

进入安装包目录

[root@localhost ~]# cd openresty-1.13.6.2

生成编译与安装文件

• --prefix=/usr/local/openresty-1.13.6.2 指定安装目录为/usr/local/openresty-1.13.6.2, 默认为/opt/openresty
• --with-luajit 开启luajit组件
• --without-http_redis2_module 禁用 http_redis2_module组件
• --with-http_iconv_module 开启 http_iconv_module组件

[root@localhost openresty-1.13.6.2]# ./configure \  --prefix=/usr/local/openresty-1.13.6.2 \  --with-luajit \ --without-http_redis2_module \ --with-http_iconv_module

编译

[root@localhost openresty-1.13.6.2]# gmake

安装

[root@localhost openresty-1.13.6.2]# gmake install

创建软链接

[root@localhost openresty-1.13.6.2]# ln -s /usr/local/openresty-1.13.6.2 /usr/local/openresty

服务启动测试

自带默认配置文件，默认服务监听80端口

使用默认的配置文件启动

[root@localhost openresty-1.13.6.2]# /usr/local/openresty/bin/openresty -p /usr/local/openresty/nginx/

通过浏览器访问测试[测试虚拟机IP为：192.168.0.254]

访问成功，OpenResty已经成功返回页面。

编写程序

切换至用户家目录

[root@localhost openresty-1.13.6.2]# cd ~

创建工作目录

[root@localhost ~]# mkdir -vp  openresty-test01/{logs,conf}mkdir: created directory 'openresty-test01'mkdir: created directory 'openresty-test01/logs'mkdir: created directory 'openresty-test01/conf'[root@localhost ~]# tree openresty-test01/openresty-test01/├── conf└── logs2 directories, 0 files

编写配置文件

注意：　如果你安装的是 openresty 1.9.3.1 及以下版本，请使用 content_by_lua 命令代替示例中的 content_by_lua_block。可使用 nginx/openresty -V 命令查看版本号。

[root@localhost ~]# cat openresty-test01/conf/nginx.confworker_processes 1; # 设置worker数量error_log logs/error.log; # 指定错误日志文件路径events {    worker_connections 1024; # 单个worker进程最大允许同时建立外部连接的数量}http {    server {        listen 8888; # 设置监听端口, 注意系统其它服务是否已占用该端口        location / {            # lua 代码块            content_by_lua_block {                ngx.say("this is lisea no.1 openresty app")            }        }    }}

运行

[root@localhost ~]# /usr/local/openresty/bin/openresty -p openresty-test01

无报错就表示运行成功

通过命令测试

[root@localhost ~]# curl 127.0.0.1:8888this is lisea no.1 openresty app

访问成功，OpenResty已经成功返回内容。

通过浏览器测试[测试虚拟机IP为：192.168.0.254, 端口为配置文件中监听设置的：8888]

访问成功，OpenResty已经成功返回内容。
