关于每天凌晨自动重启脚本/usr/local/scripts/restart_r.sh，由于该脚本只有重启进程的功能，在使用过程中有很多局限性。为了能够实现Linux中类似网卡启动：server network {start|stop|restart|reload|status}功能，在/etc/init.d/中添加了receve 启动脚本，内容为：#!/bin/sh # Start or stop receve # chkconfig:345 89 17 # description: "receve.php" # Source function library if [ -f /etc/rc.d/init.d/functions ]; then . /etc/rc.d/init.d/functions elif [ -f /etc/init.d/functions ]; then . /etc/init.d/functions elif [ -f /etc/rc.d/functions ]; then . /etc/rc.d/functions fi #定义启动关闭时,会显示是否Ok,并有颜色提示. BOOTUP=color MOVE_TO_COL="echo -en \\033[60G" SETCOLOR_SUCCESS="echo -en \\033[1;32m" SETCOLOR_FAILURE="echo -en \\033[1;31m" SETCOLOR_WARNING="echo -en \\033[1;33m" SETCOLOR_NORMAL="echo -en \\033[0;39m" #ok 为绿色 function echo_success() { [ "$BOOTUP" = "color" ] && $MOVE_TO_COL echo -n "[" [ "$BOOTUP" = "color" ] && $SETCOLOR_SUCCESS echo -n $" OK " [ "$BOOTUP" = "color" ] && $SETCOLOR_NORMAL echo -n "]" echo -ne "\r" echo -e "\n" return 0 } #failed为暗红色 function echo_failure() { [ "$BOOTUP" = "color" ] && $MOVE_TO_COL echo -n "[" [ "$BOOTUP" = "color" ] && $SETCOLOR_FAILURE echo -n $"FAILED" [ "$BOOTUP" = "color" ] && $SETCOLOR_NORMAL echo -n "]" echo -ne "\r" echo -e "\n" return 1 } #判断进程的运行状态,并记录PID,我运行着两个进程,所以要记录多次. function isrun { numpro=`/bin/ps -ef | grep "receve.php" | grep -v 'grep'|uniq|wc -l` if [ $numpro -ge 1 ];then export numpro /bin/ps -ef | grep "receve.sh" | grep -v 'grep'|grep -v grep |awk '{print $2}' >/var/run/receve.pid /bin/ps -ef | grep "receve.php" | grep -v 'grep'|grep -v grep |awk '{print $2}' >>/var/run/receve.pid export run=1 else export run=0 fi } #需要运行的脚本 RETVAL=0 ShellBin="/usr/local/scripts/receve.sh" LockFile=/var/lock/subsys/receve # See how we were called. #启动 start() { isrun if [ $run -eq 0 ];then # Start receve.php. if [ ! -f $ShellBin ];then echo "FATAL: No such programme";exit 4; fi echo -n "Starting receve: " $ShellBin & RETVAL=$? if [ $RETVAL -eq 0 ] ;then touch $LockFile echo_success else echo_failure fi return $RETVAL else echo "receve always on!" fi } #关闭 stop() { isrun if [ $run -eq 1 ];then # Stop receve.php. echo -n $"Shutting down receve: " for i in `cat /var/run/receve.pid` do kill -9 $i done RETVAL=$? if [ $RETVAL -eq 0 ] ;then rm -f $LockFile echo_success else echo_failure fi return $RETVAL else echo "receve always off!" fi } # call the function we defined case "$1" in start) start ;; stop) stop ;; restart|reload) stop start RETVAL=$? ;; status) status receve RETVAL=$? ;; *) echo $"Usage: $0 {start|stop|restart|reload|status}" exit 2 esac exit $RETVAL 给脚本加执行权限:# /bin/chmod +x /etc/init.d/receve用chkconfig添加自动启动:# /sbin/chkconfig --add receve# /sbin/chkconfig receve on
