基于OpenResty部署应用层nginx以及nginx+lua开发hello world

部署第一个nginx，作为应用层nginx[192.168.31.231]

查看安装的Nginx版本

1	[root@matrix-cache01 servers]# nginx/sbin/nginx -V

nginx+lua开发的hello world

1	[root@matrix-cache01 ~]# vi /usr/servers/nginx/conf/nginx.conf

在http部分添加

1 2	lua_package_path "/usr/servers/lualib/?.lua;;"; lua_package_cpath "/usr/servers/lualib/?.so;;";

/usr/servers/nginx/conf下，创建一个lua.conf

1 2	[root@matrix-cache01 ~]# cd /usr/servers/nginx/conf [root@matrix-cache01 conf]# vi lua.conf

server {
    listen       80;
    server_name  _;
}

在nginx.conf的http部分添加：

[root@matrix-cache01 ~]# vi /usr/servers/nginx/conf/nginx.conf
http{
    include lua.conf;
}

验证配置是否正确

1	[root@matrix-cache01 ~]# /usr/servers/nginx/sbin/nginx -t

在lua.conf的server部分添加

[root@matrix-cache01 ~]# vi /usr/servers/nginx/conf/lua.conf
location /lua {
    default_type 'text/html';
    content_by_lua 'ngx.say("hello world")';
}

验证配置是否正确

1	[root@matrix-cache01 ~]# /usr/servers/nginx/sbin/nginx -t

重新nginx加载配置

[root@matrix-cache01 ~]# /usr/servers/nginx/sbin/nginx -s reload
```  

### 访问http://192.168.31.231/lua

![](http://ww1.sinaimg.cn/large/dc05ba18gy1fhaynr45bkj20yw086jt2.jpg)

### 修改hello.lua

```bash
[root@matrix-cache01 ~]# vi /usr/servers/nginx/conf/lua/hello.lua
ngx.say("hello world! this is matrix-cache01!")

修改lua.conf

[root@matrix-cache01 ~]# vi /usr/servers/nginx/conf/lua.conf
location /lua {  
    default_type 'text/html';  
    content_by_lua_file conf/lua/hello.lua;
}

访问http://192.168.31.231/lua

查看异常日志
