（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");
