注意:监控方法可以为端口、进程、URL模拟访问方式,或者三种方法综合。

说明:由于截止到目前仅讲了if语句,因此,就请大家用if语句来实现。

  [root@oldboy-B scripts]# cat apachemon  #!/bin/sh  #created by oldboy 20110523  . /etc/init.d/functions  HTTPPRONUM=`ps -ef|grep http|grep -v grep|wc -l`  #if [ $HTTPPRONUM -lt 1 ];then  if [[ $HTTPPRONUM -lt 1 ]];then  action "httpd is not running" /bin/false  action "httpd is not running" /bin/false >/tmp/httpd.log  httpdctl restart >/dev/null 2>&1  action "httpd is restart" /bin/true  mail -s "`uname -n`'s httpd restarted at `(date)`" 31333741@qq.com  exit 1  else  action "httpd is running" /bin/true  exit 0  fi
  [root@oldboy-B scripts]# apachemon  httpd is running [确定]  [root@oldboy-B scripts]# pkill httpd  [root@oldboy-B scripts]# ps -ef |grep http |grep -v grep  [root@oldboy-B scripts]# apachemon  httpd is not running [失败]  httpd is restart [确定]  [root@oldboy-B scripts]# ps -ef|grep http|grep -v grep  root 5845 1 1 15:59 ? 00:00:00 /usr/sbin/httpd -k restart  apache 5852 5845 0 15:59 ? 00:00:00 /usr/sbin/httpd -k restart  apache 5853 5845 0 15:59 ? 00:00:00 /usr/sbin/httpd -k restart  apache 5854 5845 0 15:59 ? 00:00:00 /usr/sbin/httpd -k restart  apache 5855 5845 0 15:59 ? 00:00:00 /usr/sbin/httpd -k restart  apache 5856 5845 0 15:59 ? 00:00:00 /usr/sbin/httpd -k restart  apache 5857 5845 0 15:59 ? 00:00:00 /usr/sbin/httpd -k restart  apache 5858 5845 0 15:59 ? 00:00:00 /usr/sbin/httpd -k restart  apache 5859 5845 0 15:59 ? 00:00:00 /usr/sbin/httpd -k restart

脚本 改进

  [root@oldboy-B /]# echo oldboytest >/var/www/html/index.htm  [root@oldboy-B /]# wget -quiet -spider http://10.0.0.161/index.htm  [root@oldboy-B /]# echo $?  0  [root@oldboy-B /]# ll index.htm  ls: index.htm: 没有那个文件或目录
  [root@oldboy-B scripts]# cat apachemon1  #!/bin/sh  #created by oldboy 20110523    . /etc/init.d/functions  #HTTPPRONUM=`ps -ef|grep http|grep -v grep|wc -l` #=====>这个是基于http方式进行判断  wget -quiet -spider http://10.0.0.161/index.htm #=====>这个是基于WGET URL方式进行判断  if [ $? -ne 0 ];then  action "httpd is not running" /bin/false >/tmp/httpd.log  httpdctl restart >/dev/null 2>&1  action "httpd is restart" /bin/true >>/tmp/httpd.log  mail -s "`uname -n`'s httpd restarted at `(date)`" mail@qq.com  exit 1  else  action "httpd is running" /bin/true  exit 0  fi

真正使用时,有些输出是不需要的就去掉

  [root@oldboy-B scripts]# cat apachemon1  #!/bin/sh  #created by oldboy 20110523  #  . /etc/init.d/functions  wget -quiet -spider http://10.0.0.161/index.htm #=====>这个是基于WGET URL方式进行判断  if [ $? -ne 0 ];then  action "httpd is not running" /bin/false >/tmp/httpd.log  httpdctl restart >/dev/null 2>&1  action "httpd is restart" /bin/true >>/tmp/httpd.log  mail -s "`uname -n`'s httpd restarted at `(date)`" 31333741@qq.com  exit 1  fi

多条件判断的写法

  [root@oldboy-B scripts]# cat apachemon1  #!/bin/sh  #created by oldboy 20110523  #  . /etc/init.d/functions  HTTPPORTNUM=`netstat -lnt|grep 80|grep -v grep|wc -l`  HTTPPRONUM=`ps -ef|grep http|grep -v grep|wc -l`  wget -quiet -spider http://10.0.0.161/index.htm && RETVAL=$?  if [ $RETVAL -ne 0 ] || [ $HTTPPORTNUM -ne 1 ] || [ $HTTPPRONUM -lt 1 ] ;then  #if [ "$RETVAL" != "0" -o "$HTTPPORTNUM" != "1" -o "$HTTPPRONUM" \< "1" ] ;then  action "httpd is not running" /bin/false  action "httpd is not running" /bin/false >/tmp/httpd.log  httpdctl restart >/dev/null 2>&1  action "httpd is restart" /bin/true  mail -s "`uname -n`'s httpd restarted at `(date)`" 31333741@qq.com  exit 1  else  action "httpd is running" /bin/true  exit 0  fi
