Shell脚本判断Apache进程是否存在

linux  /  管理员 发布于 7年前   227

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。

复制代码 代码如下:
#!/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
