安装

安装说明取决于您试图安装 Supervisor 的系统是否具有互联网访问权限。

安装到有互联网接入的系统

使用 Pip 网络安装

可以使用 pip install 来安装 Supervisor：

pip install supervisor

Depending on the permissions of your system’s Python, you might need to be the root user to install Supervisor successfully using pip.

You can also install supervisor in a virtualenv via pip.

Internet-Installing Without Pip

If your system does not have pip installed, you will need to download the Supervisor distribution and install it by hand. Current and previous Supervisor releases may be downloaded from PyPi. After unpacking the software archive, run python setup.py install. This requires internet access. It will download and install all distributions depended upon by Supervisor and finally install Supervisor itself.

备注

Depending on the permissions of your system’s Python, you might need to be the root user to successfully invoke python setup.py install.

Installing To A System Without Internet Access

If the system that you want to install Supervisor to does not have Internet access, you’ll need to perform installation slightly differently. Since both pip and python setup.py install depend on internet access to perform downloads of dependent software, neither will work on machines without internet access until dependencies are installed. To install to a machine which is not internet-connected, obtain the following dependencies on a machine which is internet-connected:

Copy these files to removable media and put them on the target machine. Install each onto the target machine as per its instructions. This typically just means unpacking each file and invoking python setup.py install in the unpacked directory. Finally, run supervisor’s python setup.py install.

备注

Depending on the permissions of your system’s Python, you might need to be the root user to invoke python setup.py install successfully for each package.

Installing a Distribution Package

Some Linux distributions offer a version of Supervisor that is installable through the system package manager. These packages are made by third parties, not the Supervisor developers, and often include distribution-specific changes to Supervisor.

Use the package management tools of your distribution to check availability; e.g. on Ubuntu you can run apt-cache show supervisor, and on CentOS you can run yum info supervisor.

A feature of distribution packages of Supervisor is that they will usually include integration into the service management infrastructure of the distribution, e.g. allowing supervisord to automatically start when the system boots.

备注

Distribution packages of Supervisor can lag considerably behind the official Supervisor packages released to PyPI. For example, Ubuntu 12.04 (released April 2012) offered a package based on Supervisor 3.0a8 (released January 2010). Lag is often caused by the software release policy set by a given distribution.

备注

Users reported that the distribution package of Supervisor for Ubuntu 16.04 had different behavior than previous versions. On Ubuntu 10.04, 12.04, and 14.04, installing the package will configure the system to start supervisord when the system boots. On Ubuntu 16.04, this was not done by the initial release of the package. The package was fixed later. See Ubuntu Bug #1594740 for more information.

创建配置文件

一旦 Supervisor 安装完成，运行 echo_supervisord_conf。这将打印一个 “sample” Supervisor 配置文件到您的终端标准输出。

一旦你看到文件回显到你的终端，重新调用命令 echo_supervisord_conf > /etc/supervisord.conf。如果你没有根用户权限，这是行不通的。

如果你没有根目录权限，或者你不想把 supervisord.conf 文件放在 /etc/supervisord.conf 目录下，你可以把它放在当前目录下（echo_supervisord_conf > supervisord.conf）然后用 -c 标志启动 supervisord，以指定配置文件的位置。

“例如：supervisord -c supervisord.conf。在这种情况下，使用 -c 标志实际上是多余的，因为 supervisord 会在查找文件的其他位置之前，先在当前目录中查找 supervisord.conf，但它是可以工作的。有关 -c 标志的更多信息，请参见 运行 Supervisor。

一旦您的文件系统上有了配置文件，您就可以开始根据自己的喜好修改它。
