[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
└── 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 127.0.0.1:8888
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。
