How to make icecast as service and restart it?
提问by w3spi
I installed Icecast 2.4.3 on my server using direct downloadto get the latest version available.
我使用直接下载在我的服务器上安装了 Icecast 2.4.3以获得可用的最新版本。
In this way, I don't use the version distributed by my distribution (debian 8) and thus don't have the daemon activated by default.
通过这种方式，我不使用我的发行版 (debian 8) 分发的版本，因此默认情况下没有激活守护程序。
I found a script that I modified with my corresponding paths, but the execution is in error.
找到了一个脚本，用我对应的路径修改，但是执行出错。
The script icecast.sh:
脚本icecast.sh：

Q3: What should I do to restart Icecast automatically if the server restarts itself?
Q3: 如果服务器自行重启，我应该怎么做才能自动重启 Icecast？

The answer is to use the properpackage from either debian backportsor if you e.g. need TLS support the package from official Xiph.org repositories.
答案是使用来自debian backports的正确包，或者如果您需要 TLS 支持来自官方 Xiph.org 存储库的包。
This guarantees, that you will receive package updates without having to monitor releases yourself and figure out necessary changes.
这保证了您将收到包更新，而无需自己监控版本并找出必要的更改。
Also please note that the latest release for Linux/Unix at this time is 2.4.2, as 2.4.3 was a Windowsonly release. The code is identical if compiled for Linux/Unix.
另请注意，此时 Linux/Unix 的最新版本是2.4.2，因为 2.4.3 是仅适用于Windows 的版本。如果为 Linux/Unix 编译，代码是相同的。

- Install a package from you distro (
apt-get install icecast2,yum install icecast, whatever). Usually pakage manager also installs init scripts that will allow you start/stop Icecast. - Get your Icecast patht with
which icecastorwhereis icecast - Download Icecast, build it from source (like if you need to replace official Icecast with Icecast-kh branch or use your own compilation flags).
- Replace the original icecast binary from (2) with the one that you have build. It's always better to backup the original version, though.
/etc/inid/icecast restartorsystemctr restart icecastshould work now with your version of Icecast.- To make sure your Icecast will start after reboot run
systemctl enable icecast
- 从安装包发行版（
apt-get install icecast2，yum install icecast，等等）。通常，包管理器还会安装初始化脚本，允许您启动/停止 Icecast。 - 使用
which icecast或获取您的 Icecast 路径whereis icecast - 下载 Icecast，从源代码构建它（比如如果你需要用 Icecast-kh 分支替换官方 Icecast 或使用你自己的编译标志）。
- 将 (2) 中的原始 icecast 二进制文件替换为您已构建的二进制文件。不过，最好备份原始版本。
/etc/inid/icecast restart或者systemctr restart icecast现在应该与您的 Icecast 版本一起使用。- 确保您的 Icecast 在重启后启动
systemctl enable icecast
