linux怎樣添加開機(jī)啟動(dòng)腳本？

#?1.編輯rc.local文件 [root@localhost?~]#?vi?/etc/rc.local ? #?2.修改rc.local文件，在?exit?0?前面加入以下命令。保存并退出。 /etc/init.d/mysqld?start?????????????????????#?mysql開機(jī)啟動(dòng) /etc/init.d/nginx?start?????????????????????#?nginx開機(jī)啟動(dòng) supervisord?-c?/etc/supervisor/supervisord.conf?????????#?supervisord開機(jī)啟動(dòng) /bin/bash?/server/scripts/test.sh?>/dev/null?2>/dev/null ? #?3.最后修改rc.local文件的執(zhí)行權(quán)限 [root@localhost?~]#?chmod?+x?/etc/rc.local [root@localhost?~]#?chmod?755?/etc/rc.local

#?1.將(腳本)啟動(dòng)文件移動(dòng)到?/etc/init.d/或者/etc/rc.d/init.d/目錄下。（前者是后者的軟連接） mv?/www/wwwroot/test.sh?/etc/rc.d/init.d ? #?2.啟動(dòng)文件前面務(wù)必添加如下三行代碼，否側(cè)會(huì)提示chkconfig不支持。 #!/bin/sh?????????????告訴系統(tǒng)使用的shell,所以的shell腳本都是這樣 #chkconfig:?35?20?80????????分別代表運(yùn)行級(jí)別，啟動(dòng)優(yōu)先權(quán)，關(guān)閉優(yōu)先權(quán)，此行代碼必須 #description:?http?server?????自己隨便發(fā)揮！！！，此行代碼必須 /bin/echo?$(/bin/date?+%F_%T)?>>?/tmp/test.log ? #?3.增加腳本的可執(zhí)行權(quán)限 chmod?+x?/etc/rc.d/init.d/test.sh ? #?4.添加腳本到開機(jī)自動(dòng)啟動(dòng)項(xiàng)目中。添加到chkconfig，開機(jī)自啟動(dòng)。 [root@localhost?~]#?cd?/etc/rc.d/init.d [root@localhost?~]#?chkconfig?--add?test.sh [root@localhost?~]#?chkconfig?test.sh?on ? #?5.關(guān)閉開機(jī)啟動(dòng) [root@localhost?~]#?chkconfig?test.sh?off ? #?6.從chkconfig管理中刪除test.sh [root@localhost?~]#?chkconfig?--del?test.sh ? #?7.查看chkconfig管理 [root@localhost?~]#?chkconfig?--list?test.sh
