Shell腳本實現(xiàn)監(jiān)控kingate并自動啟動

    自己在vps做的kingate服務(wù)端,估計最近占用流量太大了,老是被服務(wù)商把我vps重啟,但kingate這個東西是一旦被強制結(jié)束掉,是無法開機啟動的,因為要把kingate.pid這個文件刪除了才能啟動,好吧,對于我們這樣的懶人來說,當然不能自己去登錄服務(wù)器去手動刪除并啟動kingate,就寫了個簡單的shell腳本來替我完成這些。
    系統(tǒng):centos 5.x
    腳本內(nèi)容:
    cat kingate.sh
    代碼如下:
    #!/bin/bash
    kingate=`ps -C kingate --no-header|wc -l`
    file=`find /usr/local/kingate/var/kingate.pid |wc -l`
    if [ "$kingate" = "1" ];then
    echo "kingate is running...."
    else
    if [ "$file" = "1" ];then
    rm -f /usr/local/kingate/var/kingate.pid
    /etc/init.d/kingate start
    sleep 1
    kingate=`ps -C kingate --no-header|wc -l`
    if [ "$kingate" = "1" ];then
    echo "kingate is ok!"
    else
    /etc/init.d/kingate start
    fi
    fi
    fi
    用crontab每隔3分鐘執(zhí)行下kingate.sh這個腳本,當然如果你不嫌浪費資源的話,還可以自己搞個郵件報警.
