# Build Apache APISIX
## 1. Install dependencies
The runtime environment for Apache APISIX requires Nginx and etcd.
So before installation, please follow the different operating systems [install Dependencies](install-dependencies.md).
## 2. Install Apache APISIX
You can install Apache APISIX in a variety of ways, including source code packages, Docker, and Luarocks.
### Installation via source release
You need to download the Apache source release first:
```shell
wget http://www.apache.org/dist/incubator/apisix/1.1/apache-apisix-1.1-incubating-src.tar.gz
tar zxvf apache-apisix-1.1-incubating-src.tar.gz
```
Install the Lua libraries that the runtime depends on:
```shell
cd apache-apisix-1.1-incubating
make deps
```
### Installation via RPM package (CentOS 7)
```shell
sudo yum install -y https://github.com/apache/incubator-apisix/releases/download/1.1/apisix-1.1-0.el7.noarch.rpm
```
### Installation via Luarocks (macOS not supported)
Execute the following command in the terminal to complete the installation of APISIX (only recommended for developers):
> Install the code for the master branch via a script
```shell
sudo sh -c "$(curl -fsSL https://raw.githubusercontent.com/apache/incubator-apisix/master/utils/install-apisix.sh)"
```
> Install the specified version via Luarocks:
```shell
# Install version 1.1
sudo luarocks install --lua-dir=/path/openresty/luajit apisix 1.1
# old luarocks not support the `lua-dir` parameter, you can remove this option
sudo luarocks install apisix 1.1
```
## 3. Manage (start/stop) APISIX Server
We can start the APISIX server by command `make run` in APISIX home folder,
or we can stop APISIX server by command `make stop`.
```shell
# init nginx config file and etcd
$ make init
# start APISIX server
$ make run
# stop APISIX server
$ make stop
# more actions find by `help`
$ make help
Makefile rules:
help: Show Makefile rules.
deps: Installation dependencies
utils: Installation tools
lint: Lint Lua source code
init: Initialize the runtime environment
run: Start the apisix server
stop: Stop the apisix server
verify: Verify the configuration of apisix server
clean: Remove generated files
reload: Reload the apisix server
install: Install the apisix
test: Run the test case
license-check: Check lua souce code for Apache License
```
## 4. Test
1. Install perl's package manager `cpanminus` first
2. Then install `test-gninx` via `cpanm`:`sudo cpanm --notest Test::Nginx IPC::Run > build.log 2>&1 || (cat build.log && exit 1)`
3. Clone source code`git clone https://github.com/openresty/test-nginx.git`;
4. Load the `test-nginx` library with perl's `prove` command and run the test cases in the `/t` directory:
* Set PERL5LIB for perl module: `export PERL5LIB=.:$PERL5LIB`
* Run the test cases: `make test`
* To set the path of nginx to run the test cases: `TEST_NGINX_BINARY=/usr/local/bin/openresty prove -Itest-nginx/lib -r t`
### Troubleshoot
If you run in to an issue `Error unknown directive "lua_package_path" in /API_ASPIX/incubator-apisix/t/servroot/conf/nginx.conf`
make sure to set openresty as default nginx. And export the path as below.
* export PATH=/usr/local/openresty/nginx/sbin:$PATH
## 5. Update Admin API token to protect Apache APISIX
Changes the `apisix.admin_key` in the file `conf/config.yaml` and restart the service.
Here is an example:
```yaml
apisix:
# ... ...
admin_key
-
name: "admin"
key: abcdefghabcdefgh
role: admin
```
When calling the Admin API, `key` can be used as a token.
```shell
$ curl http://127.0.0.1:9080/apisix/admin/routes?api_key=abcdefghabcdefgh -i
HTTP/1.1 200 OK
Date: Fri, 28 Feb 2020 07:48:04 GMT
Content-Type: text/plain
... ...
{"node":{...},"action":"get"}
$ curl http://127.0.0.1:9080/apisix/admin/routes?api_key=abcdefghabcdefgh-invalid -i
HTTP/1.1 401 Unauthorized
Date: Fri, 28 Feb 2020 08:17:58 GMT
Content-Type: text/html

{"node":{...},"action":"get"}
```
