运行shell脚本时出错

Question

我编写了一个检查ntp服务的脚本。它更新它，然后启动服务。

在下面的脚本中，我做了三件事：

1. 检查服务是否配置正确，即它正在运行。然后，退出脚本。也就是什么都不做。
2. 如果服务配置正确，那么只需启动服务并退出脚本即可。
3. 如果服务未配置，则停止服务->配置服务-> start服务。

从以上场景来看，场景1和场景3都可以正常工作。但是，在测试场景2时，它会在下面抛出错误：

~# sh ntpConfigure.sh ntpConfigure.sh:第3行: ntp _CONF.bak=/etc/ntp.conk.备份:未找到ntpd未运行/etc/init.d/ntpd未运行服务器time.myCompany.com /etc/ntp.conf配置服务已配置，启动ntp服务启动ntpd ntpConfigure.sh:第77行:回声服务已成功启动:未找到

知道它为什么要抛出这个错误吗？我检查了所有东西，但我的代码看起来不错。功能可以很好地处理上述错误。有什么想法吗？

代码：

NTP_CONF="/etc/ntp.conf"
NTP_CONF.BAK="/etc/ntp.conf.backup"

        echo "$NTPQ_SERVICE is running"

        echo "$NTPQ_SERVICE is NOT running"

        exit 0

        $NTPQ_SERVICE start
        if [ $? -eq 0 ]
        then
                echo" Service is started successfully"
                exit 0
        else
                echo "Failed to start service"
                exit 1
        fi

        $NTPQ_SERVICE stop

        $CP $NTP_CONF $NTP_CONF.BAK
        echo "Updating $NTP_CONF file with the required configurations"
        echo "restrict 127.0.0.1" >  $NTP_CONF

        echo "driftfile /etc/ntp.drift" >>  $NTP_CONF
        echo "server time.myCompany.com" >> $NTP_CONF
        if [ $? -eq 0 ]
        then
                echo "$NTP_CONF is configued properly"
                echo "Starting ntp service"
                $NTPQ_SERVICE start
                 if [ $? -eq 0 ]
                 then
                        echo "ntp service configured and started successfully"
                        echo "Configuring ntp service to start at bootup"
                        $CHKCONFIG ntpd on
                        exit 0
                 else
                        echo "Failed to start ntp service"
                        exit 1
                 fi
        else
                echo "Failed to configure ntp service"
                exit 1
        fi
fi

您漏掉了一个命令：echo"应该是第77行的echo "。
