shell脚本判断Apache进程是否存在

分类:shell编程 阅读:32657 次

写一个脚本检查Apache进程是否存在,若不存在则显示不存在,若存在则显示进程个数,当不等于10个时用红色字体通知管理员,并询问管理员是否启动Apache服务。

#!/bin/bash
#echo "$(service httpd status)"
PIDNUM=$(pgrep httpd | wc -l)
if [[ $PIDNUM -eq 0 ]];then
echo "Apache is stopped."
read -p "Do you want to start Apache?(y/n)" START
if [[ $START == y ]];then
echo "$(service httpd start)"
else
echo "You refused to start Apache."
fi
else
echo "Apache is running. Proccess number is $PIDNUM."
if [[ $PIDNUM != 10 ]];then
echo -e "\033[31mPID didn't equal 10\033[0m"
fi

fi
