2014-10-14 shell脚本练习题

回复 收藏
上一个脚本其实并不难，只要把你做过的操作整理一遍，把该有的命令写到脚本里就可以了。为什么大家都不去动手？其实厉害的大牛和普通人的区别就在于此，大牛一开始也是小白，但是他们努力，有目标，会动手去写。不要找借口说不会，那我问你，lamp你搭建成功了吗？如果搭建成功了就可以写出那个脚本来！

今天的shell练习题：写一个脚本判断你的Linux服务器里是否开启web服务？（监听80端口）如果开启了，请判断出跑的是什么服务，是httpd呢还是nginx又或者是其他的什么？ （本来还想再加一个需求，我看还是算了，不然你们又不动手了。）

         echo "System  web app is not runing "

    5. if netstat -nlp|grep -v 'grep'|grep -q ':80'; then
    6.     web_pid=`netstat -nlp|grep ':80'|awk '{print $NF}'|awk -F/ '{print $1}'`
    7.     web_ser=`ps aux|grep -v 'grep'|grep $web_pid|awk '{print $11}'`
    8.     echo "web service is on,it's main progress is '$web_ser'"
    9. else
    10.     echo "web service is off."
    11. fi
    思路：netstat -nlp查看80端口是否开启，如开启，则web服务已启动，然后通过该pid查看(ps aux)到底是哪个进程在运行；如未开启，则web服务未启动。
