OpenResty 安装 和 hello world，

OpenResty 安装 和 hello world，

（1）部署openresty

mkdir -p /usr/servers

cd /usr/servers/

yum install readline-devel pcre pcre-devel openssl openssl-devel gcc curl GeoIP-devel

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 bundle

wget https://github.com/FRiCKLE/ngx_cache_purge/archive/2.3.tar.gz

tar -xvf 2.3.tar.gz

cd 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

[

./configure --with-luajit --with-pcre --with-http_gzip_static_module --with-http_realip_module --with-http_geoip_module --with-http_ssl_module --with-http_stub_status_module

]

make && make install

cd /usr/servers/

ll

/usr/servers/luajit

/usr/servers/lualib

/usr/servers/nginx

/usr/servers/nginx/sbin/nginx -V

启动nginx: /usr/servers/nginx/sbin/nginx

（2）nginx+lua开发的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，创建一个lua.conf

server {

listen      80;

server_name  _;

}

在nginx.conf的http部分添加：

include lua.conf;

验证配置是否正确：

/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")';

}

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

重新nginx加载配置

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

访问http: http://192.168.31.187/lua

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

ngx.say("hello world");

修改lua.conf

location /lua {

default_type 'text/html';

content_by_lua_file conf/lua/test.lua;

}

查看异常日志

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

（3）工程化的nginx+lua项目结构

项目工程结构

hello

hello.conf

lua

hello.lua

lualib

*.lua

*.so

放在/usr/hello目录下

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

worker_processes  2;

error_log  logs/error.log;

events {

worker_connections  1024;

}

http {

include      mime.types;

default_type  text/html;

lua_package_path "/usr/hello/lualib/?.lua;;";

lua_package_cpath "/usr/hello/lualib/?.so;;";

include /usr/hello/hello.conf;

}

/usr/hello/hello.conf

server {

listen      80;

server_name  _;

location /lua {

default_type 'text/html';

lua_code_cache off;

content_by_lua_file /usr/hello/lua/hello.lua;

}

}

/usr/hello/lua/hello.lua

ngx.say("hello world");
