 *NOTE*: APISIX currently only supports the v2 protocol storage to etcd, but the latest version of etcd (starting with 3.4) has turned off the v2 protocol by default. You need to add `--enable-v2=true` to the startup parameter to enable the v2 protocol. The development of the v3 protocol supporting etcd has begun and will soon be available.

+
+```shell
+sudo sh -c "$(curl -fsSL https://raw.githubusercontent.com/iresty/apisix/master/utils/install-apisix.sh)"

+> Manual inspection
+
+It's a good idea to inspect the installation script from projects you don't know yet. You can do that by downloading the installation script first, looking through it so everything looks normal, then running it:
+
 ```shell
-luarocks install --lua-dir=/usr/local/openresty/luajit apisix
+curl -Lo install.sh https://raw.githubusercontent.com/iresty/apisix/master/utils/install-apisix.sh
+sudo sh install.sh
 ```
 
-If you got some error like `unknow flag --lua-dir`, this is because `luarocks` version is too low.
-We need to remove option `lua-dir` and run again: `luarocks install apisix`.

 If all goes well, you will see the message like this:
