This is a working sample of bash script which check the apache status, restart it automatically if down, and alert by telegram bot within unicode emoji.
这是一个 bash 脚本的工作示例，它检查 apache 状态，如果关闭则自动重新启动，并通过 unicode 表情符号中的电报机器人发出警报。
#!/bin/bash
telegram=(xxxxx, yyyyyy)
if ! pidof apache2 > /dev/null
then
# web server down, restart the server
echo "Server down"
/etc/init.d/apache2 restart > /dev/null
sleep 10
#checking if apache restarted or not
if pidof apache2 > /dev/null
then
for i in "${telegram[@]}"
do
curl -s -X POST https://api.telegram.org/botxxxxxx:yyyyyyyyyyyyyyyyyyyyyyyyyy/sendMessage -d chat_id="$i" -d text="`echo -e '\U0001F525'` Apache stoped on Molib Stage. Automatically restarted succesfully."
done
else
for i in "${telegram[@]}"
do
curl -s -X POST https://api.telegram.org/botxxxxxx:yyyyyyyyyyyyyyyyyyyyyyyyyy/sendMessage -d chat_id="$i" -d text="`echo -e '\U0001F525'` Apache stoped on Molib Stage. Automatically restart failed. Please check manually."
done
fi
fi

Instead of httpd try to grep "apache2". To be sure try to check services with the next command and decide the registered name of the apache webserver: service --status-all
而不是 httpd 尝试 grep “ apache2”。确保尝试使用下一个命令检查服务并确定 apache 网络服务器的注册名称： service --status-all

This work perfect in an old Debian. Remember to run with bash and not with sh.
这项工作在旧的 Debian 中非常完美。请记住使用 bash 而不是 sh 运行。
In Centos replace with httpd.
在 Centos 中替换为 httpd。
#!/bin/bash
if [ $(/etc/init.d/apache2 status | grep -v grep | grep 'Apache2 is running' | wc -l) > 0 ]
then
echo "Process is running."
else
echo "Process is not running."
fi
