環(huán)境安裝

首先創(chuàng)建一個安裝目錄

mkdir -p /usr/servers  
cd /usr/servers/

接下來安裝下面的命令一步一步來

yum install -y readline-devel pcre-devel openssl-devel gcc

wget http://openresty.org/download/ngx_openresty-1.7.7.2.tar.gz  

tar -xzvf ngx_openresty-1.7.7.2.tar.gz  

cd /usr/servers/ngx_openresty-1.7.7.2/
cd bundle/LuaJIT-2.1-20150120/  

make clean && make && make install  
ln -sf luajit-2.1.0-alpha /usr/local/bin/luajit

cd /usr/servers/ngx_openresty-1.7.7.2/bundle
wget https://github.com/FRiCKLE/ngx_cache_purge/archive/2.3.tar.gz  
tar -xvf 2.3.tar.gz  

cd /usr/servers/ngx_openresty-1.7.7.2/bundle  
wget https://github.com/yaoweibin/nginx_upstream_check_module/archive/v0.3.0.tar.gz  
tar -xvf v0.3.0.tar.gz  

cd /usr/servers/ngx_openresty-1.7.7.2  
./configure --prefix=/usr/servers --with-http_realip_module  --with-pcre  --with-luajit --add-module=./bundle/ngx_cache_purge-2.3/ --add-module=./bundle/nginx_upstream_check_module-0.3.0/ -j2  
make && make install 

cd /usr/servers/  

到此可以看到這么多的目錄

/usr/servers/luajit
/usr/servers/lualib
/usr/servers/nginx
/usr/servers/nginx/sbin/nginx -V 

啟動nginx:

/usr/servers/nginx/sbin/nginx

nginx+lua開發(fā)的hello world

vi /usr/servers/nginx/conf/nginx.conf

在http部分添加：

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

/usr/servers/nginx/conf下，創(chuàng)建一個lua.conf

server {  
    listen       80;  
    server_name  _;  
}  

在nginx.conf的http部分添加：

include lua.conf;

驗證配置是否正確：

/usr/servers/nginx/sbin/nginx -t

在lua.conf的server部分添加：

location /lua {  
    default_type 'text/html';  
    content_by_lua 'ngx.say("hello world")';  
} 

檢測語法是否正確

/usr/servers/nginx/sbin/nginx -t  

重新nginx加載配置

/usr/servers/nginx/sbin/nginx -s reload  

訪問http: http://192.168.219.133/lua

image.png

vi /usr/servers/nginx/conf/lua/test.lua

在test.lua下編寫

ngx.say("hello world"); 

修改lua.conf

location /lua {  
    default_type 'text/html';  
    content_by_lua_file conf/lua/test.lua; 
}

查看異常日志

tail -f /usr/servers/nginx/logs/error.log
