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
└── logs

2 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.conf
worker_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 127.0.0.1:8888
this 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。
