如何循环执行output_a=$(/usr/bin/redis-cli -a 123456 ping 2>&1 | awk '{print $(NF-1), $NF}') >>$LOGFILE 2>&1 echo $output_a if [ "$output_a" = "pone" ]; then $REDISCLI SLAVEOF NO ONE >>$LOGFILE 2>&1 echo "pone" else pkill keepalived >>$LOGFILE echo "kill keep" /data/keepaliveds/keepalived -f /data/keepaliveds/keepalived.conf echo "sueesss" fi

可以使用while循环来实现对该脚本的循环执行。具体代码如下：

#!/bin/bash

LOGFILE=/var/log/redis-monitor.log
REDISCLI=/usr/bin/redis-cli
PASSWORD=123456

while true
do
    output_a=$($REDISCLI -a $PASSWORD ping 2>&1 | awk '{print $(NF-1), $NF}')
    echo $output_a >> $LOGFILE 2>&1

    if [ "$output_a" = "pone" ]; then
        $REDISCLI -a $PASSWORD SLAVEOF NO ONE >> $LOGFILE 2>&1
        echo "pone" >> $LOGFILE
    else
        pkill keepalived >> $LOGFILE
        echo "kill keep" >> $LOGFILE
        /data/keepaliveds/keepalived -f /data/keepaliveds/keepalived.conf >> $LOGFILE
        echo "sueesss" >> $LOGFILE
    fi

    sleep 10
done

上面的代码将脚本放在了一个无限循环的while循环中，每次执行完毕后，会sleep 10秒钟，然后再次执行该脚本。这样就可以实现对该脚本的循环执行了。当然，你可以根据自己的需求，设置不同的循环时间。
