How to use nginx+lua+redis

1. For installation, it is recommended to download openresty. The package is relatively complete and the installation is simple and convenient;

Download address http://openresty.org/download/ngx_openresty-1.7.10.1.tar.gz

tar xzvf ngx_openresty-1.7.10.1.tar.gz
cd ngx_openresty-1.7.10.1
./configure --with-luajit

3. Modify nginx config - /usr/local/openresty/nginx/conf/nginx.conf

# Add the following to the http section to introduce redis support:

lua_package_path "/home/ngx_openresty-1.7.10.1/bundle/lua-resty-redis-0.20/lib/resty/?.lua;;";

#Close The lua script cache makes it possible to load the script every time and modify the script without restarting nginx

lua_code_cache off;

4. How to use nginx lua script

Execute the script in the config file

#lua script excute in this config
Location /lua{
            set $test "hello world.";           content_by_lua '
            ngx.header.content_type = "text/plain";
                                                                                                                                                                   '; lua script file call

location /extlua{
content_by_lua_file /home/lua_script/redis_test.lua;
}
