我写了一个脚本来检查 ntp 服务。它更新它，然后启动服务。

我在下面的脚本中做了三件事：

  1. 检查服务是否配置正确并且它正在运行。然后，只需退出脚本。即什么也不做。
  2. 如果服务配置正确，则只需启动服务并退出脚本。
  3. 如果服务没有配置，则停止服务->配置服务->启动服务。

从上述场景中，场景 1 和场景 3 工作正常。但是在测试场景 2 时，它会引发以下错误：

~ # sh ntpConfigure.sh ntpConfigure.sh: line 3: NTP_CONF.BAK=/etc/ntp.conf.backup: not found ntpd is not running /etc/init.d/ntpd is NOT running server time.myCompany.com / etc/ntp.conf 已配置服务已配置，正在启动 ntp 服务正在启动 ntpd ntpConfigure.sh：第 77 行：echo 服务已成功启动：未找到

知道为什么会抛出此错误吗？我检查了所有内容，但我的代码看起来不错。功能适用于上述错误。有任何想法吗？

代码：

#VERIFY_NTPQ="/bin/ntpq -p"
NTP_CONF="/etc/ntp.conf"
NTP_CONF.BAK="/etc/ntp.conf.backup"
NTPQ_SERVICE="/etc/init.d/ntpd"
TOUCH="/bin/touch"
GREP="/bin/grep"
CP="/bin/cp"
CHKCONFIG="/bin/chkconfig"

if [ $? -eq 0 ]
then
        isSERVICE_RUNNING=true
        echo "$NTPQ_SERVICE is running"
else
        isSERVICE_RUNNING=false
        echo "$NTPQ_SERVICE is NOT running"
fi

$TOUCH $NTP_CONF

if [ $? -eq 0 ]
then
        isSERVICE__CONFIGURED=true
        echo "$NTP_CONF is configured"
else
        isSERVICE__CONFIGURED=false
        echo "$NTP_CONF is NOT configured"
fi

if $isSERVICE_RUNNING && $isSERVICE__CONFIGURED
then
        echo "ntp service is already configured, nothing to do"
        exit 0
elif $isSERVICE__CONFIGURED
then
        echo "Service is configured already, starting ntp service"
        $NTPQ_SERVICE start
        if [ $? -eq 0 ]
        then
                echo" Service is started successfully"
                exit 0
        else
                echo "Failed to start service"
                exit 1
        fi
else
        echo "$NTP_CONF not configured, Configuring $NTP_CONF"
        echo "Stopping ntp service "
        $NTPQ_SERVICE stop
        echo "Taking backup of $NTP_CONF file to $NTP_CONF.BAK"
        $CP $NTP_CONF $NTP_CONF.BAK
        echo "Updating $NTP_CONF file with the required configurations"
        echo "restrict 127.0.0.1" >  $NTP_CONF
        echo "restrict default kod nomodify notrap" >>  $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

你拼错了一个命令： echo"应该echo "在第 77 行。
