rsync啟動腳本編寫
需求：寫一個rsync服務啟動腳本
思路：
1、首先對腳本參數個數進行判斷如果傳參個數不等於1，則echo "Usage: $0 {start|restart|stop}"
2、定義函數service，通過case進行對腳本傳參值的流程控制判斷
3、啟動服務采用命令rsync --daemon
4、停止服務采用kill -9 進程和刪除rsync的PID文件
[[email protected] test]# cat /etc/init.d/rsyncd
#!/bin/bash
#rsyncd啟動腳本
#
. /etc/init.d/functions
PID=`ps -ef|grep "rsync --daemon" |egrep -v grep |awk ‘{print $2}‘`
pidfile=/var/run/rsyncd.pid
if [ $# -ne 1 ];then
echo "Usage: $0 {start|restart|stop}"
exit 5
fi
result=$1
service() {
case $result in
start)
[ -n "$PID" ] && {
action "rsyncd up..." /bin/false
exit 9
}
rsync --daemon &>/dev/null
[ $? -eq 0 ] && action "rsyncd up..." /bin/true || action "rsyncd" /bin/false

[ -z "$PID" ] && {
action "rsyncd down..." /bin/false
exit 7
}
[ -n "$PID" ] && kill -9 $PID || action "rsyncd..." /bin/false
