• Many common first-party modules (Check auto-generated config.yaml for details)
• Dynamic Record Resizing for TLS
• brotli
• headers-more
• geoip2
• fancyindex
• OpenSSL from source

Installation

pip install -U nginx_install

or

git clone https://github.com/VermiIIi0n/nginx_install.git
cd nginx_install
pip install -U poetry
poetry install

Quick Start

Create a config.yaml, use any action as the first argument, it won't actually run if config.yaml is not found.

nginx_install uninstall --dry ## creates a config.yaml file and quits

Edit your config.yaml and run the following command to install Nginx:

nginx_install install

To uninstall Nginx, use the following command:

nginx_install uninstall

Usage

Installed by pip

nginx_install { prepare | build | install | uninstall | clean } [build_dir]

When you first run the script, you will be asked to create a config.yaml under the current directory. You may not want to run as root when creating the config.yaml file. You can also specify the file using the -c/--config option.

The first positional argument is the action to be performed.

The second positional argument is optional and is used to specify the build directory. If not specified, the default build directory is used.

When running the script for real business, you might want to run as root, because the script needs to install packages and create directories.

To just build the Nginx binary, use the following command:

nginx_install build

To just install without building, use the following command:

nginx_install install --no-build

To build and install Nginx, use the following command:

nginx_install install

build and plain install both delete the previous build directory and create a new one.

Currently only partial support for cross-compiling. If your target system is the same as the build system, you can copy the build directory to the target system and run install --no-build there.

Change -march in config.yaml if your are installing on systems with different CPU

By default, core installer will use -march=native flag, this may cause problems on other systems.

Check your -march by running gcc -march=native -Q --help=target | grep march on your target system and change -march in config.yaml accordingly.

Installed by git clone

If you cloned the repository, use the following command to run the script:

poetry run `which python` nginx_install <...>

Dry Run

Use --dry to run the script in dry-run mode. In this mode, the script will not change anything outside of build_dir but will print the commands to be executed.

nginx_install --dry build

no root should be required if you have access to the build directory.

Configuration

The config.yaml file is used to specify the version of Nginx to be installed, the modules to be included, and the build options.

Use -c/--config to specify the path of the config.yaml file. By default, it is config.yaml under the current directory.

If not specified, the script will search for the ./config.yaml file, and if not found, it will ask you to create one.

If -q/--quiet is specified, the script will not ask you to create one and will exit with an error if not found.

Useful options in config.yaml:

• version: The version of Nginx to be installed. Can be stable, mainline, latest, or a simple spec version (e.g. 1.21.3, ^1.24.0, <=1.26.0).
• pymodule_paths: A list of paths to Python modules. Convenient for adding custom Installer classes.

Customization

You can easily add your own modules to modify the installation of Nginx (e.g. add custom modules, change build options, etc.).

All Installer classes are descendants of the BaseInstaller class.

Every Installer class has 5 async methods corresponding to the 5 stages of the installation process:

• prepare
• build
• install
• uninstall
• clean

They all accept a special context parameter, which contains useful information about the installation process. You must override these methods in inherited classes.

During installation running, installers go through prepare, build, install and clean stages. During uninstallation running, installers go through uninstall and clean stages.

A special Installer called core represents the core binary installer of Nginx. In every stage, the core installer methods are called first, and then the methods of other installers are called. The order of the other installers is random. This is done to reduce build time.

You can access core through the context parameter. Parameters like Nginx configure options are stored in core and can be modified.

Context

The context parameter is a dictionary containing the following attributes:

• build_dir: The build directory.
• cfg: The Config object from the config.yaml file.
• core: The NginxInstaller object.
• verbose: A boolean value indicating whether to print verbose information.
• dry_run: A boolean value indicating whether to run the script in dry-run mode. You should respect this value in your custom installers. Don't actually change anything if dry_run is True.
• client: A httpx.AsyncClient object. You can use it to download files from the internet.
• logger: You can use it to log information.
• progress: A rich.progress.Progress object. You can use it to show a progress bar.
• run_cmd: An async function to run shell commands. You should use it to run shell commands in your custom installers. When dry_run is True, it will only print the command to be executed.
• download: An async function to download files from the internet. You should use it to download files in your custom installers. It automatically shows a progress bar when downloading files.
