ให้ Shoutcast เปิดอัตโนมัติหลายสถานี
ผมทดลองเปิดสถานีวิทยุออนไลน์ ซึ่งมีหลายสถานี (port) และต้องการให้มันเปิดแบบอัตโนมัติในตอนเปิด server ก็ไปเจอวิธีการและ code ในเว็บนี้
ลองทำตามโค๊ดข้างล่าง
#!/bin/bash # # chkconfig: 345 91 35 # description: Starts and stops sc_serv.<br /> # You know, the mp3 streaming thang. # # Version 1.3 (nov 4 2001) # Now with more revisions! System now checks for pid file before cat # to display so that we receive no error messages. System also displays # pids as we are killing old processes. Profanity was removed from the<br /> # startup messages. Tests for a pid file before reporting success. Displays # the relay server name when we start the daemon up, so that we know # which servers are getting booted. Pushed the success marker over to the<br /> # right and added [] because I am just a slave to fashion. # # Version 1.2 (nov 3 2001) # Same exact shit, but runs as nobody for security reasons. Just # in case we are worried about buffer overflows or whatnot. # # Version 1.1 (nov 3 2001) # Starts stops and restarts jobs. Also checks for existing daemons # before calling a start, and exits without starting new ones. This # prevents you from being a dumbass and starting multiple listeners # on the same port. I would suggest using the restart command # in these cases. Also creates a shoutcast.pid file that can be used # to discover all of the (many) pids used by shoutcast when running. # # Version 1.0 (nov 3 2001)<br /> # Starts and stops successfully.<br /> # Kills old jobs on start command. Dirty, but<br /> # does the job well enough. Tested functional on # mandrake version 8.1 but should work on redhat<br /> # or any other distro that supports a standard<br /> # sysv startup script. # # Instructions for use. # 1: untargzip shoutcast into the directory of your choosing # 2: copy sc_serv into the /usr/sbin directory<br /> # 3: Create the directory /etc/shoutcast # 4: copy the shoutcast.conf file into your /etc/shoutcast dir. # 5: Edit the shoutcast.conf file to match your needs. # 6: Make as many more conf files as needed to support<br /> # multiple streams. Be sure to edit these files so that # you are not starting multiple shoutcast servers that # are either listening or broadcasting on the same port. # 7: Copy this file into the /etc/rc.d/init.d directory # 8: chmod this file +x (chmod ug+x /etc/rc.d/init.d/shoutcast) # 9: run chkconfig --add shoutcast from the /etc/rc.d/init.d dir. # 10:Run /etc/rc.d/init.d/shoutcast start<br /> # 11:Drink a beer, or light one up, and enjoy the tunes. # # Source networking configuration. . /etc/sysconfig/network # Check that networking is up. This line may cause an error on incompatible # distributions. Remove it if necessary. Also remove if the startup always # fails for no apparent reason. [[ ${NETWORKING} = "no" ]] && exit 0<br /> <br /> <br /> stop (){ <a class="hashtag" href="/tags/First">#First</a> we want to kill the original servers, so we don't get errors. echo "Killing old shoutcast servers." for oldpid in `ps -A | grep sc_serv | cut -c 0-6`; do kill -9 $oldpid if [[ $1 == "-v" ]] then echo $oldpid fi done rm -f /var/run/shoutcast.pid }<br /> <br /> <br /> start (){ <a class="hashtag" href="/tags/Now">#Now</a> we can start the servers up. if [[ $1 == "-v" ]]<br /> then echo "Starting up the new shoutcast servers.

ขั้นตอนการติดตั้ง
- สร้างไฟล์ /etc/init.d/shoutcast แล้วเปลี่ยน attr เป็น 755
- copy ไฟล์ sc_serv (ที่ดาวน์โหลดมา) ไปไว้ที่ /usr/bin
- สร้างโฟล์เดอร์ /etc/shoutcast แล้วนำไฟล์คอนฟิกมาใส่ไว้ในนี้ จะกี่ไฟล์ก็ได้ ตอนเปิดเครื่องมันจะ start ให้หมด
