网站环境进程守护

这个是我2022年年底回家过年，而那段时间服务器偶尔会被攻击，偶尔会宕机，家里又处于偏远地区，没有网络，也重启不了环境，如果期间宕机，那么可能是10多天的宕机，虽然没啥损失，但是一会影响SEO，二会影响需要到我网站查阅代码的用户，所以就想着让服务器能有自己重启环境的能力。

所以，我添加了几个进程守护脚本，放到宝塔计划任务，保证环境不死，不是宝塔的也可以进行参照修改，代码如下，执行频率为一分钟：

1、数据库进程守护

#!/bin/bash
status=`service mysqld status | grep running | wc -l`  
port=`netstat -lnt | grep 3306 | wc -l`  
pid=`ps -ef | grep mysql | grep -v grep | wc -l`
if [ $status -ne 1 ] && $port -ne 1 ] && [ $pid -ne 2 ];then
    /etc/init.d/mysqld restart
else
    echo "mysql running!!!"
fi
#!/bin/bash
status=`service mysqld status | grep running | wc -l`  
port=`netstat -lnt | grep 3306 | wc -l`  
pid=`ps -ef | grep mysql | grep -v grep | wc -l`
if [ $status -ne 1 ] && $port -ne 1 ] && [ $pid -ne 2 ];then
    /etc/init.d/mysqld restart
else
    echo "mysql running!!!"
fi
#!/bin/bash
status=`service mysqld status | grep running | wc -l`  
port=`netstat -lnt | grep 3306 | wc -l`  
pid=`ps -ef | grep mysql | grep -v grep | wc -l`
if [ $status -ne 1 ] && $port -ne 1 ] && [ $pid -ne 2 ];then
    /etc/init.d/mysqld restart
else
    echo "mysql running!!!"
fi

2、nginx进程守护

#!/bin/bash
pid=`ps -ef | grep nginx | grep root | grep /www/server/nginx/sbin/nginx | grep /www/server/nginx/conf/nginx.conf | wc -l`
status=`service nginx status | grep running | wc -l`
if [ $pid -ne 1 ] && [ $status -ne 1 ];then
    /etc/init.d/nginx restart
else
    echo "nginx running!!!"
fi
#!/bin/bash
pid=`ps -ef | grep nginx | grep root | grep /www/server/nginx/sbin/nginx | grep /www/server/nginx/conf/nginx.conf | wc -l`
status=`service nginx status | grep running | wc -l`
if [ $pid -ne 1 ] && [ $status -ne 1 ];then
    /etc/init.d/nginx restart
else
    echo "nginx running!!!"
fi
#!/bin/bash
pid=`ps -ef | grep nginx | grep root | grep /www/server/nginx/sbin/nginx | grep /www/server/nginx/conf/nginx.conf | wc -l`
status=`service nginx status | grep running | wc -l`
if [ $pid -ne 1 ] && [ $status -ne 1 ];then
    /etc/init.d/nginx restart
else
    echo "nginx running!!!"
fi

3、PHP进程守护

以下为PHP5.6，如果添加其他的，请修改56，比如8.0将56修改为80。

#!/bin/bash
pid=`ps -ef | grep php-fpm | grep root | grep process | grep master | grep 56 | wc -l`
status=`service php-fpm-56 status | grep running | wc -l`
if [ $pid -ne 1 ] && [ $status -ne 1 ];then
    /etc/init.d/php-fpm-56 restart
else
    echo "php56 running!!!"
fi
#!/bin/bash
pid=`ps -ef | grep php-fpm | grep root | grep process | grep master | grep 56 | wc -l`
status=`service php-fpm-56 status | grep running | wc -l`
if [ $pid -ne 1 ] && [ $status -ne 1 ];then
    /etc/init.d/php-fpm-56 restart
else
    echo "php56 running!!!"
fi
#!/bin/bash
pid=`ps -ef | grep php-fpm | grep root | grep process | grep master | grep 56 | wc -l`
status=`service php-fpm-56 status | grep running | wc -l`
if [ $pid -ne 1 ] && [ $status -ne 1 ];then
    /etc/init.d/php-fpm-56 restart
else
    echo "php56 running!!!"
fi

4、memcached进程守护

#!/bin/bash
pid=`ps -ef | grep memcached | wc -l`
if [ $pid -ne 2 ];then
    /etc/init.d/memcached restart
else
    echo "memcached running!!!"
fi
#!/bin/bash
pid=`ps -ef | grep memcached | wc -l`
if [ $pid -ne 2 ];then
    /etc/init.d/memcached restart
else
    echo "memcached running!!!"
fi
#!/bin/bash
pid=`ps -ef | grep memcached | wc -l`
if [ $pid -ne 2 ];then
    /etc/init.d/memcached restart
else
    echo "memcached running!!!"
fi

5、凌晨环境重启

根据自己需要添加。

#!/bin/bash
/etc/init.d/memcached restart >> /dev/null
/etc/init.d/php-fpm-81 restart >> /dev/null
/etc/init.d/php-fpm-80 restart >> /dev/null
/etc/init.d/php-fpm-74 restart >> /dev/null
/etc/init.d/php-fpm-73 restart >> /dev/null
/etc/init.d/php-fpm-72 restart >> /dev/null
/etc/init.d/php-fpm-70 restart >> /dev/null
/etc/init.d/php-fpm-56 restart >> /dev/null
/etc/init.d/nginx restart >> /dev/null
/etc/init.d/mysqld restart >> /dev/null
echo 已执行环境重启！
#!/bin/bash
/etc/init.d/memcached restart >> /dev/null
/etc/init.d/php-fpm-81 restart >> /dev/null
/etc/init.d/php-fpm-80 restart >> /dev/null
/etc/init.d/php-fpm-74 restart >> /dev/null
/etc/init.d/php-fpm-73 restart >> /dev/null
/etc/init.d/php-fpm-72 restart >> /dev/null
/etc/init.d/php-fpm-70 restart >> /dev/null
/etc/init.d/php-fpm-56 restart >> /dev/null
/etc/init.d/nginx restart >> /dev/null
/etc/init.d/mysqld restart >> /dev/null
echo 已执行环境重启！
#!/bin/bash
/etc/init.d/memcached restart >> /dev/null
/etc/init.d/php-fpm-81 restart >> /dev/null
/etc/init.d/php-fpm-80 restart >> /dev/null
/etc/init.d/php-fpm-74 restart >> /dev/null
/etc/init.d/php-fpm-73 restart >> /dev/null
/etc/init.d/php-fpm-72 restart >> /dev/null
/etc/init.d/php-fpm-70 restart >> /dev/null
/etc/init.d/php-fpm-56 restart >> /dev/null
/etc/init.d/nginx restart >> /dev/null
/etc/init.d/mysqld restart >> /dev/null
echo 已执行环境重启！

其实还有环境不全，因为我没用，所以就没写，你也可以按照我的脚本写一个，比如Redis。
